11、在一張打方格的紙上投一枚直徑為1的硬幣，方格的邊長(zhǎng)(方格邊長(zhǎng)設(shè)為a)要多少才能使得硬幣與方格線(xiàn)不相交的概率小于1% ()
A、a＞910 B、a＞109
C、1＜a＜109 D、0＜a＜910
C解析：硬幣與方格線(xiàn)不相交，則a＞1時(shí)，才可能發(fā)生，在每一個(gè)方格內(nèi)，當(dāng)硬幣的圓心落在邊長(zhǎng)為a－1，中心與方格的中心重合的小正方形內(nèi)時(shí)，硬幣與方格線(xiàn)不相交，故硬幣與方格線(xiàn)不相交的概率P＝(a－1)2a2.，由(a－1)2a2＜1%，得1＜a＜109.
12、集合A＝{(x，y)|x－y－10，x＋y－10，xN}，集合B＝{(x，y)|y－x＋5，xN}，先后擲兩顆骰子，設(shè)擲第一顆骰子得點(diǎn)數(shù)記作a，擲第二顆骰子得數(shù)記作b，則(a，b)B的概率等于 ()
A.14 B.29

答案：12
15、把一顆骰子投擲兩次，第一次出現(xiàn)的點(diǎn)數(shù)記為m，第二次出現(xiàn)的點(diǎn)數(shù)記為n，方程組mx＋ny＝3，2x＋3y＝2，只有一組解的概率是__________。
1718 解析：由題意，當(dāng)m2n3，即3m2n時(shí)，方程組只有一解、基本事件總數(shù)為36，滿(mǎn)足3m＝2n的基本事件有(2,3)，(4,6)共兩個(gè)，故滿(mǎn)足3m2n的基本事件數(shù)為34個(gè)，故所求概率為P＝3436＝1718.
16、在圓(x－2)2＋(y－2)2＝8內(nèi)有一平面區(qū)域E：x－40，y0，mx－y0)，點(diǎn)P是圓內(nèi)的任意一點(diǎn)，而且出現(xiàn)任何一個(gè)點(diǎn)是等可能的、若使點(diǎn)P落在平面區(qū)域E內(nèi)的概率最大，則m＝__________.
解析：如圖所示，當(dāng)m＝0時(shí)，平面區(qū)域E的面積最大，則點(diǎn)P落在平面區(qū)域E內(nèi)的概率最大。
三、解答題：本大題共6小題，共70分。
17、(10分)某公司在過(guò)去幾年內(nèi)使用某種型號(hào)的燈管1 000支，該公司對(duì)這些燈管的使用壽 命(單位：小時(shí))進(jìn)行了統(tǒng)計(jì)，統(tǒng)計(jì)結(jié)果如下表所示
分組 [500，900) [900，1 100) [1 1001 300) [1 300，1 500) [1 500，1 700) [1 700，1 900) [1 900，＋)
頻數(shù) 48 121 208 223 193 165 42
頻率[]
(1)將各組的頻率填入表中；
(2)根據(jù)上述統(tǒng)計(jì)結(jié)果，計(jì)算燈管使用壽命不足1 500小時(shí)的頻率；
(3)該公司某辦公室新安裝了這種型號(hào)的燈管15支，若將上述頻率作為概率，估計(jì)經(jīng)過(guò)1 500小時(shí)約需換幾支燈管、
解析：
分組 [500，900) [900，1 100) [1 1001 300) [1 300，1 500) [1 500，1 700) [1 700，1 900) [1 900，＋)
頻數(shù) 48 121 208 223 193 165 42
頻率 0.048 0.121 0.208 0.223 0.193 0.165 0.042
(2)由(1)可得0.048＋0.121＋0.208＋0.223＝0.6，
所以，燈管使用壽命不足1 500小時(shí)的頻率是0.6.
(3)由(2)只，燈管使用壽命不足1 500小時(shí)的概率為0.6.
150.6＝9，故經(jīng)過(guò)1 500小時(shí)約需換9支燈管、
18、(12分)袋中有大小、形狀相同的紅、黑球各一個(gè)，現(xiàn)有放回地隨機(jī)摸取3次，每次摸取一個(gè)球。
(1)一共有多少種不同的結(jié)果？請(qǐng)列出所有可能的結(jié)果；
(2)若摸到紅球時(shí)得2分，摸到黑球時(shí)得1分，求3次摸球所得總分為5的概率。
解析：(1)一共有8種不同的結(jié)果，列舉如下：
(紅，紅，紅)、(紅，紅，黑)、(紅，黑，紅)、(紅，黑，黑)、
(黑、紅，紅)、(黑，紅，黑)、(黑，黑，紅)、(黑、黑、黑)、
(2)記“3次摸球所得總分為5”為事件A，
事件A包含的基本事件為：
(紅，紅，黑)、(紅，黑，紅)、(黑，紅，紅)
事件A包含的基本事件數(shù)為3.
由(1)可知，基本事件總數(shù)為8，
所以事件A的概率為P(A)＝38.
19、(12分)將一顆質(zhì)地均勻的正方體骰子(六個(gè)面的點(diǎn)數(shù)分別為1,2,3,4,5,6)先后拋擲兩次，記第一次出現(xiàn)的點(diǎn)數(shù)為a，第二次出現(xiàn)的點(diǎn)數(shù)為b.設(shè)復(fù)數(shù)z＝a＋bi.
(1)求事件“z－3i為實(shí)數(shù)”的.概率；
(2)求事件“復(fù)數(shù)z在復(fù)平面內(nèi)的對(duì)應(yīng)點(diǎn)(a，b)滿(mǎn)足(a－2)2＋b29”的概率。
解析：(1)z－3i為實(shí)數(shù)，
即a＋bi－3i＝a＋(b－3)i為實(shí)數(shù)，b＝3.
又b可取1,2,3,4,5,6，故出現(xiàn)b＝3的概率為16.
即事件“z－3i為實(shí)數(shù)”的概率為16.
(2)由已知，b的值只能取1,2,3.
當(dāng)b＝1時(shí)，(a－2)28，即a可取1,2,3,4；
當(dāng)b＝2時(shí)，(a－2)25，即a可取1,2,3,4；
當(dāng)b＝3時(shí)，(a－2)20，即a可取2.
綜上可知，共有9種情況可使事件成立。
又a，b的取值情況共有36種，
所以事件“點(diǎn)(a，b)滿(mǎn)足(a－2 )2＋b29”的概率為14.
20、(12分)汶川地震發(fā)生后，某市根據(jù)上級(jí)要求，要從本市人民醫(yī)院報(bào)名參加救援的護(hù)理專(zhuān)家、外科專(zhuān)家、心理治療專(zhuān)家8名志愿者中，各抽調(diào)1名專(zhuān)家組成一個(gè)醫(yī)療小組與省專(zhuān)家組一起赴汶川進(jìn)行醫(yī)療求助，其中A1，A2，A3是護(hù)理專(zhuān)家，B1，B2，B3是外科專(zhuān)家，C1，C2是心理治療專(zhuān)家。
(1)求A1恰被選中的概率；
(2)求B1和C1不全被選中的概率。
解析：(1)從8名志愿者中選出護(hù)理專(zhuān)家、外科專(zhuān)家、心理治療專(zhuān)家各1名，其一切可能的結(jié)果為：
(A1，B1，C1)，(A1，B1，C2)，(A1，B2，C1)，(A1，B2，C2)，(A1，B3，C1)，(A1，B3，C2)，(A2，B1，C1)，(A2，B1，C2)，(A2，B2，C1)，(A2，B2，C2)，(A2，B3，C1)，(A2，B3，C1)，(A2，B3，C2)，(A3，B1，C1)，(A3，B1，C2)，(A3，B2，C1)，(A3，B2，C2)，(A3，B3，C1)，(A3，B3，C2)、共有18個(gè)基本事件、
用M表示“A1恰被選中 ”這一事件，則
M包括(A1，B1，C1)，(A1，B1，C2)，(A1，B2，C1)，(A1，B2，C2)，(A1，B3，C1)，(A1，B3，C2)、共有6個(gè)基本事件、
所以P(M)＝618＝13.
(2)用N表示“B1和C1不全被選中”這一事件，則 其對(duì)立事件N表示“B1和C1全被選中”這一事件，
由N包括(A1，B1，C1)，(A2，B1，C1)，(A3，B1，C1)，共有3個(gè)基本事件，
所以P(N)＝318＝16，
由對(duì)立事件的概率公式得P(N)＝1－P(N)＝1－16＝56.
21、(12分)設(shè)關(guān)于x的一元二次方程x2＋2ax＋b2＝0.
(1)若a是從－4，－3，－2，－1四個(gè)數(shù)中任取的一個(gè)數(shù)，b是從1,2,3三個(gè)數(shù)中任取的一個(gè)數(shù)，求上述方程有實(shí)根的概率；
(2)若a是從區(qū)間[－4，－1]任取的一個(gè)數(shù)，b是從區(qū)間[1,3]任取的一個(gè)數(shù)，求上述方程有實(shí)根的概率、
解析：設(shè)事件A為“方程x2＋2ax＋b2＝0有實(shí)根”、
當(dāng)a＜0，b＞0時(shí)，方程x2＋2ax＋b2＝0有實(shí)根的充要條件為a＋b0.
(1)基本事件共12個(gè)：(－4,1)，(－4,2)，(－4,3)，
(－3,1)，(－3,2)，(－3,3)，(－2,1)，(－2,2)，(－2,3)，(－1,1)，(－1,2)，(－1,3)、
其中第一個(gè)數(shù)表示a的取值，第二個(gè)數(shù)表示b的取值、事件A中包含9個(gè)基本事件，事件A發(fā)生的概率為
P(A)＝912＝34.
(2)試驗(yàn)的全部結(jié)果所構(gòu)成的區(qū)域?yàn)?/p>
{(a，b)|－4－1,13}，構(gòu)成事件A的區(qū)域?yàn)閧(a，b)|－4－1,13，a＋b0}，
所求概率為這兩區(qū)域面積的比。
所以所求的概率P＝32－122232＝23.
22、(12分)某單位要在甲、乙、丙、丁4人中安排2人分別擔(dān)任周六、周日的值班任務(wù)(每人被安排是等可能的，每天只安排一人) 。
(1)共有多少種安排方法？
(2)其中甲、乙兩人都被安排的概率是多少？
(3)甲、乙兩人中至少有一人被安排的概率是多少？
解析：(1)安排情況如下：
甲乙，甲丙，甲丁，乙甲，乙丙，乙丁，丙甲，丙乙，丙丁，丁甲，丁乙，丁丙、故共有12種安排方法、
(2)甲、乙兩人都被安排的情況包括：“甲乙”，“乙甲”兩種，故甲、乙兩人都被安排(記為事件A)的概率為
P(A)＝212＝16.
(3)方法一：“甲、乙兩人中至少有一人被安排”與“甲、乙兩人都不被安排”這兩個(gè)事件是對(duì)立事件，∵甲、乙兩人都不被安排的情交包括：“丙丁”，“丁丙”兩種，則“甲、乙兩人都不被安排的概率為212＝16”
甲、乙兩人中至少有一人被安排(記為事件B)的概率P(B)＝1－16＝56.
方法二：甲、乙兩人中至少有一人被安排的情況包括：“甲乙，甲丙，甲丁，乙甲，乙丙，乙丁，丙甲，丙乙，丁甲，丁乙”共10種，甲、乙兩人中至少有一人被安排(記為事件B)的概率P(B)＝1012＝56.

第三部分 閱讀理解：(共20 小題, 每小題2分, 滿(mǎn)分40分)
閱讀下列短文, 從每題所給的四個(gè)選項(xiàng)A、B、C、D中選出最佳選項(xiàng)。
A
After battling hard times and danger for over nine months, British teenager Mike Perham made history last month as the youngest person to sail solo around the world.
The 17-year-old made the record after he cleared the Panama Canal and then sailed through the Caribbean and got home across the Atlantic.
Mike is only three months younger than Zac Sunderland, the 17-year-old American boy who had taken the crown as the youngest solo around-the-world sailor in July.
The two youngsters met in Cape Town in South Africa as they crossed the globe in different directions. Mike insisted they were not rivals(競(jìng)爭(zhēng)對(duì)手). “No. It's two teenagers going out there, living their dream and having the adventure of a lifetime,” he said.
Mike may be young, but he is no stranger to sailing adventures. He picked up the hobby at the age of 6 when his father took him out in a small boat on a local lake. Father and son sailed separate boats across the Atlantic when Mike was 14, making him the youngest person to cross that ocean solo. That record gave him the taste for this even greater challenge.
On the recent journey, the scariest moment for Mike came when his sailboat was hit by storms in the southern Indian Ocean.
“We were picked up by what felt like a 60-foot wave and threw down on our side at 90 degrees,” he said.
“It felt like I was going right over. Stuff was flying around and I just thought ‘Oh no’.”
At other times, he had to dive into the Pacific and fix problems. He tied himself to the boat, jumped into the water and went to work with a knife in 30-second dives underneath the boat to cut a rope away.
Mike said he felt proud that he made his dream come true. “You've got to have confidence in yourself that you will make it,” he said.

A migraine(偏頭痛) can cause disabling pain. People may not fed back to normal for hours or even days. Migraines are most common among young adults and middle-aged people. In the United States， about eighteen percent of women and six percent of men are reported having migraines.
People who suffer from migraines can find that different “triggers” (誘因)in different people may get a headache started. Stress can act as a trigger. So can chocolate in some people. Many migraine sufferers say hot weather and low barometric pressure (大氣壓) can act as triggers. But researchers say they did not have much scientific evidence of thatuntil now.
In a new study， a team examined the medical records of seven thousand hospital patients. The patients had visited the emergency room at Beth Israel Deaconess Medical Center in Boston，Massachusetts，because of a headache. More than two thousand of them had been found to have a migraine.
The team then compared those records to weather conditions in the twenty-four hours before the patients visited. For every increase of five degrees Celsius in air temperature，the patients had a seven and one-half percent higher risk of migraine. Decreases in barometric pressure two to three days the patients also appeared to trigger off headaches，but to a lesser extent.
The researchers found no evidence that air pollution influenced headaches. But they could not rule out the possibility of a smaller effect similar to that seen earlier for strokes.
A separate study has found that age，gender and where a person has extra body fat may affect the risk of migraine. It found that overweight people between the ages of twenty and fifty-five may have a higher risk. On average，those who were larger around the middle were more likely to have migraines than those of the same age with smaller waistlines.
The study involved twenty-two thousand people. It was led by Lee Peterlin. She says early results suggest that losing weight in the stomach area may help younger people who experience migraines，especially women.
61.From the first paragraph，we can infer .
A. a migraine can make people unable to walk
B. a migraine can prevent people from acting normally
C. a migraine can cause people to leave home for days
D. a migraine can get people to suffer from mental disorder
62.The underlined word “that” in Paragraph 2 refers to .
A. chocolate acting as a trigger B. stress acting as a trigger
C. hot weather and low barometric pressure acting as a trigger
D. high air pressure acting as a trigger
63.What any affect the highest risk of migraine according to the passage?
A. Age. B. Conditions. C. Gender. D. Overweight.
64.According to the passage，headaches are influenced least by .
A. body weight B. barometric pressure C. air temperature D. air pollution
65.In the opinion of Lee Peterlin，a person who has a migraine should .
A. avoid gathering fat in the stomach area B. eat more sweet food every day
C. stay warm in good weather D. keep away from polluted air

Whatever the mind can conceive (構(gòu)想) and believe. it can achieve.
Would you agree with the statement that a dream is born from an idea-a simple idea conceived in the mind?
Born in the 19th century，two brothers had an idea which eventually became their passionate (熱衷的) and consuming dream. Their never-ending pursuit of that dream was rewarded with an accomplishment that changed the world travel.
On Friday December 17，1903 at 10:35 a.m.，the Wright brothers(Wilbur and Orville) achieved their dream. They flew the world's first power-driven，heavier-than -air machine in which man made free， controlled，and sustained flight. This memorable wonder took place at Kitty Hawk，North Carolina, USA，on a cold windy morning.
The dream started with an idea that was planted in their minds by a toy given to them by their father. In the world of the toys，“l(fā)ate in the autumn of 1878，our father came into the house one evening with some object partly hidden in his hands，and before we could see what it was， he tossed it into the air. Instead of falling to the floor，as we expected，it flew across the room till it struck the ceiling, where it fluttered (飄動(dòng)) a while，and finally sank to the floor.” This simple toy made of bamboo，cork and stretched rubber bands，fascinated the Wright brothers and sparked their lifelong interest in human flight.
The Wright brothers were great thinkers. They enjoyed learning new things. First，they recycled broken parts，built a printing press and opened their own printing office. Their interest moved to bicycles and in 1893， they opened the Wright Cycle Company where they sold and repaired bicycles. But Wilbur (the elder brother) had his mind set on something more exciting. He decided to seriously pursue flying.
The brothers spent many hours researching，testing their machines and making improvements after unsuccessful attempts at human flight. What started out as a hobby soon became a passion. With determination and patience they realized their dream in 1903.
66.Which of the following is the closest in meaning to the underlined sentence?
A. Nothing is impossible to a willing heart. B. The early bird catches the worm.
C. Success relies on persistence. D. No pains， no gains.
67.When did they succeed in their first attempt to fly?
A. In 1898. B. In 1903. C. In 1893. D. In 1878.
68.What made them start the idea to work on human flight?
A. Bicycles they sold and repaired. B. Kites they once flew when young.
C. A toy given by their father. D. The printing office they started.
69. Who had the idea to invent a machine that could fly?
A. Father. B. Wilbur. C. Orville. D. None.
70.What is the best title for this passage?
A. The Wright brothers and their dream B. The Wright brothers
C. The flight D. How to travel
D
Like many other small boys, I was fascinated by cars, not least because my oldest brother was a bit of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend. Every so often, one of those magazines would run an article on the “Car of the Future”. They featured unconventional styling and things like small nuclear reactors as power sources. Yet, frankly, my car doesn’t do anything that my brother’s Studebaker didn’t do. It goes, it stops, it burns gasoline, it plays music. I still have to steer it, and it still runs into things if I don’t steer it carefully.
But guess what? All of these things are subject to change in the not-so-distant future. It will still go and stop, but it may not burn gasoline, I may not have to steer it, and it may be a lot better at not running into things.
Airbags aren't the be-all and end-all in safety. In fact, considering the recent news about people occasionally being killed by their airbags in low-speed collisions (碰撞),they obviously still need some development. But they aren't going away, and in fact, you can expect to see cars appearing with additional, side-impact airbags, something some European car manufacturers already offer.
Better than systems to minimize (使減少到最低限度) injury in the event of an accident，however, are systems that minimize the likelihood of an accident happening in the first place. Future cars may be able to eliminate many of the major causes of accidents, including drunk-driving, tailgating (與前車(chē)距離過(guò)近) and sleepiness. Cars could be equipped with sensors that can detect alcohol in a driver's system and prevent the car from being started, for example. Many accidents are caused by people following the car in front too closely. As early as next year, you'll be able to buy cars with radar-equipped control systems. If the radar determines you're closing too quickly with the car in front, it will ease up on the throttle (油門(mén)). For city streets, expect other radar devices that will give advance warning that the car in front of you has slowed abruptly (突然地) and you should step on the brakes-or that may even brake for you.
Will cars eventually be able to drive themselves? There's no reason to think it won't be technically possible, and Mercedes is working on a system that can brake, accelerate and steer a vehicle down a highway on its own. Nobody really expects people to give up all control to their cars, but such systems could be used as failsafe systems to keep cars on the road and bring them safely to a stop even if the driver suddenly became disabled.
71. Why was the author fascinated by cars?
A. Because other small boys liked to own a car of their own, too.
B. Because he read exotic things about cars in his brother's magazines.
C. Because his oldest brother loved to take him to places in his car.
D. Because he subscribed to cool car magazines.
72. By saying “my car doesn't do anything that my brother's Studebaker didn’t do”, the author
Means that_____.
A. my car is far better than my brother's
B. my car is not as good as my brother's
C. not much has changed in the performance of cars so far
D. much improvement has been made in the design of cars recently
73. Which of the following statements is true of airbags?
A. They are in need of further improvement.
B. They are going to disappear gradually.
C. They kill people instead of protecting them in low-speed collisions.
D. They are a standard feature of European cars.
74. According to the author, what will future cars do if the sensors detect alcohol in the driver's
system?
A. They will give a warning in advance. B. They will brake automatically.
C. They will ease up on the throttle. D. They will not start.
75. Which of the following statements is true according to the last paragraph?
A. People will give up all control to their cars.
B. Cars will be able to drive themselves.
C. No cars will ever break down on the roads.
D. Cars will all be equipped with failsafe systems.

In our culture, the sources of what we call a sense of “mastery” —feeling important and worthwhile—and the sources of what we call a sense of “pleasure”—finding life enjoyable—are not always the same. In the past women often were told “You can’t have it all.” Sometimes what the speaker really is saying is: “You choose a career, so you can’t expect to have closer relationships or a happy family life.” or “You have a wonderful husband and children—what’s all this about wanting a career?” But today women need to_____________, if they are to feel good about themselves.
Our study shows that, for women, well-being has two aspects. One is mastery, which includes self-respect, a sense of control over your life, and low levels of anxiety and depression. Mastery is closely related to the “doing” side of life, to work and activity. Pleasure is the other aspect, and it is made up of happiness, satisfaction and optimism. It is tied more closely to the “feeling” side of life. The two are independent of each other. A woman could be high in mastery and low in pleasure, and vice versa(反之亦然). For example, a woman who has a good job, but whose mother has just died, might be feeling very good about herself and in control of her work life, but the pleasure side could be damaged for a time.
The concepts of mastery and pleasure can help us identify the sources of well-being for women, and correct past mistakes. In the past, women were encouraged to look only at the feeling side of life as the source of all well-being. But we know that both mastery and pleasure are important. And mastery seems to be achieved largely through work. In our study, all the groups of employed women were valued significantly higher in mastery than women who were not employed.
A woman’s well-being is developed when she takes on multiple roles. At least by middle adulthood, the women who were involved in a combination of roles—marriages, motherhood, and employment—were the highest in well-being, in spite of warnings about stress and strain.

紅蘋(píng)果的滋味
□ 葉晶晶
沉甸甸的蘋(píng)果，掛在枝頭，是紅艷艷的驚喜；品在口中，潤(rùn)在心底，是人生成長(zhǎng)的美妙滋味。
——題記
漫步少年人生路，穿過(guò)風(fēng)風(fēng)雨雨。驀然回首，人生旅途中，我已品嘗過(guò)許多紅蘋(píng)果?？墒牵憧稍?，我的人生蘋(píng)果究竟是什么滋味？
月華如水，微風(fēng)拂面。輕倚欄桿，回憶的湖面泛起層層漣漪。
紅蘋(píng)果曾是淡淡的酸澀，那是人生驛站中理智的自責(zé)與自省。記得十二歲那年的春節(jié)，我貪嘴吃了爸爸待客的紅蘋(píng)果，爸爸生氣了，狠狠地批評(píng)了我。這次我沒(méi)有撒嬌，沒(méi)有摔門(mén)而出。我低下了頭，向爸爸認(rèn)了錯(cuò)。爸爸很驚愕，片刻，他明白了：“女兒長(zhǎng)大了！”夜深人靜，我細(xì)細(xì)地品味浸在心底的紅蘋(píng)果。那是一種深深的愧疚，是淡淡的酸澀，是對(duì)自省醞釀出的心靈修養(yǎng)的美好積淀。
紅蘋(píng)果是甜甜的清爽，那是人生成長(zhǎng)的磊落和豁達(dá)。高一入學(xué)后，我特別喜歡和朋友一起望月亮，說(shuō)夢(mèng)想。這天夜里，宿舍里熄燈了，我又點(diǎn)起蠟燭鉆研難題，同宿舍的一位好友一口氣吹滅了蠟燭，大罵我是“一人違紀(jì)，殃及池魚(yú)”，我心里好委屈，因?yàn)槲冶鼱T夜讀恰恰是為了明天給她補(bǔ)習(xí)功課。我簡(jiǎn)直要?dú)庹?，然而我畢竟是長(zhǎng)大了，想到宿舍這個(gè)大局，沖天的怒火倏地化為一臉微笑。我說(shuō)：“朋友，謝謝你的提醒！”好友也笑了，丟過(guò)來(lái)一個(gè)紅蘋(píng)果。那晚的蘋(píng)果，甜甜的，爽爽的，我的心胸顯示出可行大船般的豁達(dá)和瀟灑。
紅蘋(píng)果是綿長(zhǎng)的醇香，那是人生成長(zhǎng)的沉穩(wěn)和睿智。今年的教師節(jié)，我們班舉辦“愛(ài)師尊師”晚會(huì)，晚會(huì)開(kāi)始前，主持人突然病倒了，班長(zhǎng)讓我代為主持。心有膽怯，但卻之不恭，沒(méi)辦法，我硬著頭皮上臺(tái)做了主持，沒(méi)想到晚會(huì)大獲成功。會(huì)后，班長(zhǎng)犒勞我一個(gè)紅蘋(píng)果。我笑嘻嘻地接受了。那只紅蘋(píng)果好香，好醇，細(xì)細(xì)回味，心里泛起的是一絲絲氣定神閑，是瀟瀟灑灑的自信和從容。
記憶的浪花，一片接著一片地沖到岸邊。輕倚欄桿，耳邊響起一位智者的話(huà)語(yǔ)：“自然的蘋(píng)果，其味道或許是單一的，然而當(dāng)紅蘋(píng)果融進(jìn)了生活的味道，便會(huì)幻化出許多神奇的滋味，并且，隨著人生經(jīng)歷的不斷豐富，紅蘋(píng)果的滋味將會(huì)更加奇妙無(wú)比。
月華隱退，旭日東升，微風(fēng)拂面，翹首東方。遠(yuǎn)處人生的園林，沉甸甸的蘋(píng)果掛在枝頭，又是一串串更加紅艷艷的驚喜。
[名師點(diǎn)評(píng)]本文有三個(gè)亮點(diǎn)：一是文章標(biāo)題“紅蘋(píng)果的滋味”亮麗獨(dú)特，又能藝術(shù)地揭示主旨；二是本文以“人生的紅蘋(píng)果”為中心意象，從多個(gè)角度、多個(gè)層次抒寫(xiě)成長(zhǎng)的感覺(jué)，議論內(nèi)容、抒情內(nèi)容都新穎深刻；三是語(yǔ)言頗具文采，排比、對(duì)偶、比喻運(yùn)用巧妙，再加上豐富的聯(lián)想和想象，使文章在發(fā)展等級(jí)“有文采”一項(xiàng)中獨(dú)領(lǐng)風(fēng)騷。

A
When traveling, it’s important to learn about the customs and etiquette(禮儀) of the global village. What we consider polite behavior at home isn't always accepted outside our borders.
● Etiquette of Gift Giving
Gift giving should be a happy, positive experience. When selecting a present for someone in Netherlands, don't purchase fancy kitchen knives or scissors. Giving sharp, pointy objects as gifts is considered unlucky. Be careful when presenting flowers to a friend or a business partner in Russia. Yellow blooms suggest cheat or a relationship break up. Traditionally, red carnations are placed on the tombs of the dead. Writing cards or notes while visiting South Korea, be mindful of your pen's ink color. Writing a person's name in red ink traditionally suggests that the person has passed away-an important point to remember when giving a birthday card.
● Eating Customs
Being early or on time is viewed as being rude, too eager or even greedy in Venezuela. If you are invited to someone's home for a meal, it's recommended that you arrive 10 minutes later than the requested time. When having a meal in Egypt, don’t use the salt shaker (鹽瓶). It's insulting to your host to spread salt on your food, which means that you find the meal terrible. Japan is a very polite nation, and their fondness for etiquette extends to the use of chopsticks. According to Japanese custom, if you're in the middle of eating, use the opposite end of your chopsticks to secure food from a shared plate. When doing business in Turkey, it’s the custom for your host to pay for your meal. Requests to split the bill won’t be accepted. If you would like to pay your fair share, Turks recommend inviting your host to a follow-up meal.
21. Which of the following is true according to the passage?
A. Giving a fancy kitchen knife to a friend from Russia is a good choice.
B. You can use blue ink to write notes to your friend from South Korea.
C. Dining with Japanese, one can use either end of the chopsticks to get food from shared plates.
D. Invited to a meal, one should arrive earlier to show respect for the host.
22. What does the underlined word “insulting” in Paragraph 3 refer to?
A. Respectful. B. Challenging. C. Indifferent. D. Offensive.
23. Where is this passage probably from?
A. A news report. B. A travel essay.
C. A culture column. D. A food magazine.
B
Individuality is the particular character, or aggregate (total) of qualities that distinguishes one person or thing from others. Many artists late in the last century were in search of a means to express their individuality. Modern dance was one of the ways some of these people sought to free their creative spirit. At the beginning there was no exacting technique, no foundation from which to build. In later years, trial, error and genius founded the techniques and the principles of the movement. Eventually, innovators (改革者) even drew from what they considered the dread (令人恐懼的)ballet, but first they had to get rid of all that was academic so that the new could be discovered. The beginnings of modern dance were happening before Isadora Duncan, but she was the first person to bring the new dance to general audiences and see it accepted and acclaimed (稱(chēng)贊).
her search for a natural movement form sent her to nature. She believed movement should be as natural as the swaying of the trees and the rolling waves of the sea, and should be in harmony with the movements of the Earth. Her great contributions are in three areas.
First, she began the expansion of the kinds of movement that could be used in dance. Before Duncan danced, ballet was the only type of dance performed in concert. In the ballet the feet and legs were emphasized, with virtuosity (高超技巧) shown by complex, codified positions and movements. Duncan performed dance by using her body in the freest possible way. Her dance stemmed from her soul and spirit. She was one of the pioneers who broke tradition so others might be able to develop the art.
her second contribution lies in dance costume. She rejected ballet shoes and stiff costumes. These were replaced with flowing Grecian (希臘式的) tunes, bare feet, and unbound hair. She believed in the natural body being allowed to move freely, and her dress displayed this ideal.
her third contribution was in the use of music. In her performances she used the symphonies of great masters including Beethoven and Wagner, which was not the usual custom.
she was as exciting and eccentric (怪異) in her personal life as in her dance.
24.According to the passage, what did nature represent to Isadora Duncan?
A.Something to conquer. B.A model for movement.
C.A place to find peace. D.A symbol of disorder.
Pared to those of the ballet, Isadora Duncan’s costumes were less _______.
A.costly B.colorful C.graceful D.restrictive
26. We can infer from the passage that the author _________.
A. appreciates modern dance very much B. dislikes Isadora Duncan’s dance
C. thinks highly of individuality D. knows a lot about modern arts
27. Which of the following would be the best title for the passage?
A.Artists of the Last Century B.Evolution of Dance in the 20th Century
C.Natural Movement in Dance D.A Pioneer in Modern Dance
C
since Edmund Hillary and Tenzing Norgay climbed Mount Everest, Mount Qomolangma’s peak is no longer a lonely place and is turning into a trash heap(垃圾堆).
so far, more than 350 climbers have successfully reached the peak. And they have complained about waiting for hours in the bottlenecks (狹窄路段) on the way to the peak, a situation that isn’t just uncomfortable — it’s cold and windy up there — but downright dangerous. If bad weather strikes, climbers can and do die.
As a matter of fact, the dangerous crowds aren’t the only problem on Qomolangma. All those climbers need to bring a lot of gear—and much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world’s largest dump. Here’s mountaineer Mark Jenkins writing in National Geographic about the state of Qomolangma: “The two standard routes, the Northeast Ridge and the Southeast Ridge, are disgustingly polluted with oxygen cans and torn tents everywhere.”
But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountianeer Paul Thelen and his friend Eberhard Schaaf are part of the annual Eco Everest Expedition, which has been cleaning up rubbish from base camps to the peak since . So far they’ve collected over 13 tons of garbage.
some of that rubbish is even being used for a higher purpose. As part of the Mount Everest 8844 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage brought down the mountain by climbers. They’ve transformed the cans and oxygen tanks—and in one case, part of the remains of a helicopter—into 74 pieces of art that have already gone on exhibition in Nepal’s capital. Part of the profit from sales will go to the Everest Peakers Association, which has helped collect tons of rubbish on the slopes of the mountain.
28. What do we learn about the bottlenecks on the way to Mount Qomolangma’s peak?
A. They are relatively safe. B. They are often crowded.
C. They are very easy to pass. D. They are sites of base camps.
29. What does the underlined word “gear” mean?
A. Equipment for climbing mountains.
B. The food climbers brought onto the mountain.
C. Some important machines used for the bottlenecks.
D. Some rubbish found on the mountain.
30. The group of 15 Nepali artists_________.
A. created works of art using rubbish from Qomolangma
B. were employed by the Everest Peakeers Association
C. climbed Qomolangma and collected 1.5 tons of trash
D. painted 74 beautiful pictures of Mount Qomolangma’s peak
31. What can be the best title for the text?
A. Eco Everest Expedition Proves Successful
B. Qomolangma Has Become A Huge Mess
C. Test Yourself Against Qomolangma
D. Recycle Rubbish On Qomolangma

students from Florida International University in Miami walked on water Thursday for a class assignment. To do it, they wore aquatic (水上的)shoes they designed and created.
Alex Quinones was the first to make it to the other side of a 175-foot lake on campus in record time—just over a minute. Quinones, who wore oversized boat-like shoes，also won last year and will receive $ 500. Students had to wear the aquatic shoes and make it across the lake in order to earn an “A” on the assignment for Architecture Professor Jaime Canaves, Materials and Methods Construction Class. “It's traditional in a school of architecture to do boats out of cardboard for a boat race. I thought our students were a little bit more special than that,” Canaves said. “We decided to do the walk on water event to take it to the next level.”
A total of 79 students competed in the race this year in 41 teams. Only 10 teams failed to cross the lake. Others who fell got back up and made it to the end. The race is open to all students and anyone in the community. The youngest person to ever participate was a 9-year-old girl who competed in place of her mother, while the oldest was a 67-year-old female.
A large crowd on campus joined Canaves as he cheered on the racers. He shouted encouraging words, but also laughed as some unsteadily made their way to the end.
“A part of this is for them to have more understanding of designing and make it work better,” he said. It is also a lesson in life for the students.
“Anything, including walking on water, is possible, if you do the research，test it and go through the design process seriously.”
32. For what purpose did the students take part in the race?
A. To go across the lake to school.
B. To test their balance on the water.
C. To pass Professor Canaves’ class.
D. To win the prize money of $ 500.
33. Which of the following statements is true according to the passage?
A. The students wore shoes distributed by Professor Canaves to walk across the lake.
B. The students who fell into the water were criticized seriously by the Professor.
C. Most students finished the class assignment successfully.
D. The students took part in the race to challenge their physical abilities.
34. What can we infer from the passage?
A. Alex Quinones is a top student in the university.
B. It’s a custom for the people in the community to get involved in student activities.
C. The student who made it to the end in the race would succeed in their professional career.
D. Professor Canaves attaches importance to hands-on learning experience.
35. The purpose of the passage is to ___________.
A. show his approval of the unique teaching style
B. report an interesting assignment
C. inspire teachers to be more creative
D. encourage more people to take part in the race

Of the many unpleasant emotions we can experience, fear may top the list. 36 . Fear can also keep us from pursuing the things in life that really matter -- like following our dreams, and developing important relationships. I have some ideas, though, of how to be free from fear.
? Experience fear.
I used to be very afraid of speaking in front of people. I would get sweaty palms and my stomach would be so tied up that I wouldn't be able to eat. However, each time I spoke, I noticed afterwards that it wasn't that bad. Things I fear are never as bad in reality as I make them out in my mind. 37 .
? Create space.
The first and most important step to being fearless is to create some space between ourselves and the emotion of fear. This isn't accomplished by ignoring the fear, or trying to talk ourselves out of it. 38 . In fact, a recent research shows that by simply admitting the emotion we actually begin to reverse the “fight or flight(逃避)” response in the body.
? Control the breath and feel the fear.
Once we acknowledge the presence of fear, the second step is to control the breathing so that it becomes slower and gentler. We try to make the breath just a little bit longer, and feel how fear manifests(展現(xiàn)) in the body. 39 .
With practice, we can create enough space between us and the emotion of fear so that we're able to replace a fearful thought with a positive one. 40 . For instance, before I get up to speak in front of a group of people, I imagine that the audience is positively impressed by what I say and that I manage to complete the speech successfully.
A. Space is created only when we can honestly acknowledge that fear exists.
B. We can imagine a positive outcome for whatever we're about to do.
C. Fear, if left uncontrolled, can even destroy our life.
D. So one way to get rid of fear is to simply push ourselves to do things that we fear.
E. When we can see a positive outcome in our mind, fear no longer holds us back.
F. But fear is more than just physically unpleasant.
G. As we pay attention to the physical symptoms of fear, we can see fear objectively.

The Great Barn Adventure
One morning when I was 11, I explored the town’s abandoned round grain barn(谷倉(cāng)). I found a chained sliding door that was wide enough for me to pass through.
Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (升降機(jī)井) that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller.
I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands, I began climbing the wall.
After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and found…absolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher(滅火器),which I’d always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldn’t breathe. I was going to choke to death, and they’d probably never even find my body.
Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky.
I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I’m not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.
56. When the author got inside the barn, he _______.
A. noticed a man on the elevator
B. opened the chained sliding door

58. After getting out of the chained door, the author might feel _______.
A. inspired B. relieved C. surprised D. disappointed

Wikipedia: The Online Know-It-All
If you want to find out a piece of information about anything, the best place to search for it is Wikipedia. The name “Wikipedia” is from the Hawaiian word wiki, meaning “quick”. This online encyclopedia (百科全書(shū)) is written by thousands of people around the world. Anyone with Internet access can write, add or make changes to Wikipedia articles if he or she finds it incorrect or not well written. In this way, people who know a lot about a certain subject can write about it even if they are not university professors. But contributions cannot damage Wikipedia because many experienced editors are watching pages and techies (技術(shù)專(zhuān)家) can write editing programs to keep track of or correct bad edits. Where there are disagreements on how to present facts, editors work together to arrive at an article that fairly represents current expert opinion on the subject.
Wikipedia is quite different from paper-based reference sources in important ways. Unlike printed encyclopedias, it is continually created and updated, with articles on historic events appearing within minutes, rather than months or years.
What’s more, Wikipedia includes articles written in about 285 languages. This fact makes it one of the few websites on the Internet that are truly international. It was started in by Larry Sanger and Jimmy Wales, as a free online English-language encyclopedia project. Since its creation, it has grown rapidly into one of the largest reference websites, attracting nearly 500 million unique visitors monthly. There are more than 77,000 active contributors working on more than 22,000,000 articles in different languages. As of today, there are 4,396,866 articles in English.
so, if you are looking for some information, why not try Wikipedia? It’s free, multilingual，and informative.
56. According to the passage, what is Wikipedia?
A. A free website encyclopedia.B. A computer game.
C. A free encyclopedia in book form.D. An online university.
57. From the passage we know that ______.
A. Wikipedia catches a wide audience
B. Wikipedia only charges users a small fee
C. incorrect editions might do great harm to Wikipedia
D. it will take long to update the information on Wikipedia
58. Where can we probably read the passage?
A. In a story book.B. In a research report.
C. In a science magazine.D. In a travel brochure.

“Thanks for coming,” Everett said, shaking hands with Mr. Hanson, the town councillor(議員).
“I’m curious about the ideas in your letter.” Mr. Hanson nodded toward the parking lot near where they stood. “Please tell me more.”
Everett took a deep breath. “Ever since the school closed two years ago, this area has become worse. But if we clean up the litter and repair the fence, it will be a great place for a skateboard park.” Mr. Hanson scanned the broken concrete, nodding. “The old school is being adapted to a community arts centre. This area could become a vital part of the neighbourhood again.”
“Here’s a picture of a skateboard park in another town. Look how busy it is.” Everett was relieved that the community representative seemed receptive to the idea. Mr. Hanson studied the photograph, and then asked, “If town council provides the money, how will you and your friends contribute?” Everett felt optimistic now. “We’ll help design and build the ramps(坡道). More experienced boarders could give lessons to raise money!” Everett’s voice was enthusiastic.
however, Mr. Hanson said, “We’ll still need parking spaces, and the neighbours will not like late-night noise. They might worry about the crime of deliberately damaging public property and….”
“The skateboard park would use only the back corner, which isn’t near any houses. Since young people already hang out here, why not give them something fun and physically active to do in their free time?” The lines over Mr. Hanson’s forehead unwrinkled(舒展), and Everett’s hopes rose again. “If everyone works together,” Everett thought, “maybe this idea will become reality.”
56. Where were Everett and Mr. Hanson talking?
A. In the city hall.B. Outside a park.
C. Near the parking lot. D. In the art centre.
57. Everett was trying to persuade Mr. Hanson to _____.
A. beautify the neighbourhood
B. cut the area of the parking lot
C. build an art centre for children

創(chuàng)新就意味著用新的角度看問(wèn)題。

高三作文訓(xùn)練初探
高三作文訓(xùn)練不同于高一、高二階段的訓(xùn)練，高一、高二側(cè)重培養(yǎng)寫(xiě)作習(xí)慣 和熟悉各種文體的寫(xiě)作，高三則需要培養(yǎng)綜合寫(xiě)作能力，培養(yǎng)應(yīng)試作文的能力。前幾年，高三作文訓(xùn)練一般以給材料寫(xiě)議論文為主，但是高考作文“假如記憶可以移植”為高三作文訓(xùn)練敲 響了警鐘--不能再讓材料議論文的寫(xiě)作模式禁錮學(xué)生的思想。習(xí)慣于模式作文指導(dǎo)的老師，習(xí)慣于模式寫(xiě)作的學(xué)生，如何在高三作文訓(xùn)練中改變?cè)瓉?lái)的文風(fēng)，確實(shí)是一個(gè)值得深思的問(wèn)題。筆者在這里結(jié)合作文訓(xùn)練實(shí)際，對(duì)高三階段作文指導(dǎo)做一些探討。?
首先，高三作文訓(xùn)練應(yīng)該以培養(yǎng)學(xué)生的創(chuàng)新能力為出發(fā)點(diǎn)，進(jìn)行必要的思維訓(xùn)練?
“假如記憶可以移植”已經(jīng)傳遞給我們作文指導(dǎo)的信息，即在培養(yǎng)學(xué)生的聯(lián)想力和想象力上下功夫。未來(lái)社會(huì)對(duì)人才創(chuàng)新能力的要求是毋庸置疑的，作文本身又是學(xué)生思想和認(rèn)識(shí)水平的體現(xiàn)，如果作文訓(xùn)練不符合社會(huì)對(duì)人才的客觀(guān)要求，不能說(shuō)不是作文教學(xué)的失誤。只要教師科學(xué)引導(dǎo)學(xué)生的聯(lián)想和想象力，創(chuàng)新能力的培養(yǎng)也不是解決不好的教學(xué)難題。?
我認(rèn)為，在對(duì)學(xué)生進(jìn)行思維訓(xùn)練的過(guò)程中，教師首先要合理設(shè)置引發(fā)學(xué)生思考的材料，明確訓(xùn)練目標(biāo)。具體操作時(shí)，教師要充當(dāng)一個(gè)點(diǎn)火者，讓學(xué)生自己去燃燒思想的火焰。既然是思維訓(xùn)練，就應(yīng)注意引發(fā)學(xué)生思考，解決“寫(xiě)什么”而不是“怎么寫(xiě)”的問(wèn)題。學(xué)生插上了想象的 翅膀，然后才能在文字的.天空飛翔。我曾經(jīng)用一組幾何圖形訓(xùn)練學(xué)生的想象力。材料是從直線(xiàn)、曲線(xiàn)、等腰三角形、梯形、不完整的圓中任意選擇一個(gè)圖形，展開(kāi)聯(lián)想，聯(lián)系實(shí)際，自擬題目作文。在學(xué)生討論之前，我提示學(xué)生由圖形到擬題的思維程序是：圖形→象征意義→ 聯(lián)想人事→確定觀(guān)點(diǎn)→擬題。比如，由直線(xiàn)想到無(wú)盡的人生之路，生活中每個(gè)人都要在人生 路上留下足跡，擬題為“路漫漫其修遠(yuǎn)兮，吾將上下而求索”。學(xué)生有了思維樣本，思路就打開(kāi)了：有的把曲線(xiàn)想象成波峰浪谷，想到人生有輝煌也有失意，擬題為“平平淡淡才是 真 ”；有的把倒立的三角形想象成古代計(jì)時(shí)用的沙漏，擬題為“莫等閑白了少年頭”；有的把梯形想象成人生的舞臺(tái)，每個(gè)人都是舞臺(tái)上的角色，主張“扮演好生活的角色”；有的把不完整的圓說(shuō)成是人生的缺憾，想到古代四大美人雖有各自的缺憾，但并沒(méi)有影響她們的美，擬題為“缺憾也是一種美”；有個(gè)同學(xué)把所有的圖形都考慮進(jìn)去，認(rèn)為每個(gè)圖形都代表一種人生，認(rèn)為人生有平凡、有波折、有輝煌、有缺憾，但只要充滿(mǎn)信心，就能活出生活的色彩，擬題為“活出生活的色彩”。由此可見(jiàn)，通過(guò)思維訓(xùn)練，學(xué)生對(duì)事物有了深刻認(rèn)識(shí)，能夠抓住事物的本質(zhì)，文章的立意就不會(huì)流于俗套。而我們一直在向?qū)W生強(qiáng)調(diào)的中心思想問(wèn)題 也就得到了落實(shí)。
?
第二，高三作文訓(xùn)練應(yīng)該尊重學(xué)生的創(chuàng)作主體意識(shí)，讓他們寫(xiě)出真情實(shí)感

7.(2013湖北)i為虛數(shù)單位，設(shè)復(fù)數(shù)z1，z2在復(fù)平面內(nèi)對(duì)應(yīng)的點(diǎn)關(guān)于原點(diǎn)對(duì)稱(chēng)，若z1=2-3i，則z2=________.
解析：在復(fù)平面內(nèi)，復(fù)數(shù)z=a+bi與點(diǎn)(a，b)一一對(duì)應(yīng).
∵點(diǎn)(a，b)關(guān)于原點(diǎn)對(duì)稱(chēng)的點(diǎn)為(-a，-b)，
則復(fù)數(shù)z2=-2+3i.
答案：-2+3i
8.(2013天津)已知a，bR，i是虛數(shù)單位.若(a+i)(1+i)=bi，則a+bi=________.
解析：∵(a+i)(1+i)=a+ai+i+i2
=(a-1)+(a+1)i.
又由已知(a+i)(1+i)=bi，得a-1=0，a+1=b.解得a=1，b=2，所以a+bi=1+2i.
答案：1+2i
9.(2013江蘇)設(shè)z=(2-i)2(i為虛數(shù)單位)，則復(fù)數(shù)z的模為_(kāi)_______.
解析：∵z=(2-i)2=3-4i，
|z|=32+-42=5.
答案：5
