7年級(jí)下冊(cè)英語重點(diǎn)知識(shí)點(diǎn)1
1.have“有”啥用法。
have是英語中很有用的動(dòng)詞,基本含義是“有”。如課文中的“Ihaveasoccerball.”have在he,she,it后面要變成has,即:一般現(xiàn)在時(shí)態(tài)第三人稱單數(shù)形式。
如:Hehasabasketball.
have當(dāng)動(dòng)詞“有”的意思時(shí),句式是:
陳述句:Ihaveanicebag.我有一個(gè)不錯(cuò)的包。
疑問句:Doyouhaveanicebag?Yes,Ido.No,Idon't.
你有一個(gè)漂亮的包嗎?是的,我有。不,我沒有。
否定句:Idon'thaveanicebag.
我沒有漂亮的包
have與其它的詞組合成詞組、短語,就不表示有了,其意思由后面的名詞決定。如:
haveclasses(上課);havebreakfast(吃早飯);haveagoodtime(玩得高興);havesports(進(jìn)行體育活動(dòng));haveadayoff(休假)等等。
have與therebe句型的區(qū)別
therebe是表示“在某處存在某物”,而have則是表示所屬的意思,即“擁有”,通常主語是人。我們來看兩個(gè)句子:
Thereisabookonthedesk.書桌上有一本書。
Ihavemanybooks.我有很多本書。
2.Let's的用法。
句中的let's表示“讓我們”,這個(gè)句型表示說話人的建議,建議說話人和聽話人一起去做某事情,它是letus的縮寫形式,但用letus表示的是說話人建議聽話人讓說話人干某事。如:
Let'sgotoschool.讓我們到學(xué)校去。
Let'splaybasketball.讓我們打籃球去。
MrWang,letusreadthebooknow.
王老師,讓我們讀課文吧。

一.動(dòng)詞be(is,am,are)的用法
我(I)用am, 你(you)用are,is跟著他(he),她(she),它(it)。單數(shù)名詞用is,復(fù)數(shù)名詞全用are。變否定,更容易,be后not加上去。變疑問,往前提,句末問號(hào)莫丟棄。還有一條須注意,句首大寫莫忘記。
二.this,that和it用法
(1)this和that是指示代詞,it是人稱代詞。
(2)距離說話人近的人或物用this, 距離說話人遠(yuǎn)的人或物用that。如:
This is a flower. 這是一朵花。(近處)
That is a tree. 那是一棵樹。(遠(yuǎn)處)
(3)放在一起的兩樣?xùn)|西,先說this, 后說that。如:
This is a pen. That is a pencil. 這是一支鋼筆。那是一支鉛筆。
(4)向別人介紹某人時(shí)說This is…, 不說That is…。如:
This is Helen. Helen, this is Tom. 這是海倫,海倫,這是湯姆。
(5)This is 不能縮寫, 而That is可以縮寫。如:
This is a bike. That’s a car. 這是一輛自行車。那是一輛轎車。
(6)打電話時(shí),介紹自己用this, 詢問對(duì)方用that。如:
—Hello! Is that Miss Green? 喂,是格林小姐嗎?
—Yes, this is. Who’s that? 是的,我是,你是誰?
注意:雖然漢語中使用“我”和“你”,但英語中打電話時(shí)絕不可以說:I am…, Are you…?/Who are you?
(7)在回答this或that作主語的疑問句時(shí), 要用it代替this或that。如:
?、佟狪s this a notebook? 這是筆記本嗎?
—Yes, it is. 是的,它是。
?、凇猈hat’s that? 那是什么?
—It’s a kite. 是只風(fēng)箏。
