以下是GRE閱讀長(zhǎng)難句實(shí)例分析。
In order to understand the nature of the ecologist’s investigation，we may think of the density-dependent effects on growth parameters as the "signal" ecologists are trying to isolate and interpret，one that tends to make the population increase from relatively low values or decrease from relatively high ones，while the density-independent effects act to produce "noise" in the population dynamics. (5)
為了能理解生態(tài)學(xué)家們所從事的研究的性質(zhì)，我們可以把那些作用于增長(zhǎng)參數(shù)的密度依賴效應(yīng)視作生態(tài)學(xué)家們力圖將其分離并予以解釋的“信號(hào)”，正是這一信號(hào)傾向于使種群從相對(duì)較低的數(shù)值遞增，或從相對(duì)較高的數(shù)值遞減;而與此同時(shí)，那些密度獨(dú)立效應(yīng)起到的作用則構(gòu)成了種群動(dòng)態(tài)變化中的“噪音”。
難句類型：復(fù)雜修飾、插入語、省略
解釋：句子不僅很長(zhǎng)，而且有兩個(gè)地方看上去不舒服，第一：think of ..as…不是很常見，其實(shí)think of 這個(gè)詞組就等于consider, imagine，加上后面的as就是把….認(rèn)為是…的意思。第二個(gè)不習(xí)慣的地方是signal后面的大段修飾語，不但長(zhǎng)度很長(zhǎng)，而且在signal后面還省略了一個(gè)that，正常應(yīng)該是the signal that ecologists are trying to isolate and interpret，與前面見過對(duì)that的省略不同的是，這次that在句中不是句子的賓語，而是不定式動(dòng)詞的賓語。
意群訓(xùn)練：In order to understand the nature of the ecologist’s investigation, we may think of the density-dependent effects on growth parameters as the "signal" ecologists are trying to isolate and interpret, one that tends to make the population increase from relatively low values or decrease from relatively high ones, while the density-independent effects act to produce "noise" in the population dynamics.

以下是GRE閱讀長(zhǎng)難句實(shí)例分析。
For one thing, no population can be driven entirely by density-independent factors all the time.(5)難句類型：正話反說
請(qǐng)思考：如果文中說這句話的前提是：all population are driven by two (and only two) categories of growth parameters, one is density-independent factors, and the other is density-independent factors. 那么作者說上面的這句話有什么用意。
解釋：本句雖然貌不驚人，但本書既然將其收錄進(jìn)來，并標(biāo)出難度5，就意味著其中有怪異之處。值得一提的是，本文前面曾把控制種群密度的因素分為兩種，一種叫做density-dependent factors(這里簡(jiǎn)稱d-d因素)，另一種叫做dentsity-independent factors(簡(jiǎn)稱d-I因素)。原文的直譯雖然好懂，但是總令人感覺說得不甚明白。顯然，GRE或GMAT的作者不可能隨便說一句無關(guān)痛癢的話，那么沒有任何種群能夠在所有的時(shí)間全被d-I因素所控制，其真正意思是什么呢?就是：一切種群都必然在某個(gè)時(shí)間內(nèi)受到d-d因素的控制。本句是ETS在考試中慣用的正話反說的典型例子，請(qǐng)讀者深沉體會(huì)。本句在文章中也是理解作者態(tài)度的關(guān)鍵所在。
意群訓(xùn)練：For one thing, no population can be driven entirely by density-independent factors all the time.

以下是GRE閱讀長(zhǎng)難句實(shí)例分析。
The increase in the numbers of married women employed outside the home in the twentieth century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers，previously，in many cases，the only women employers would hire. (5)
二十世紀(jì)已婚婦女在家庭以外就業(yè)的人數(shù)不斷增加，這與家務(wù)的機(jī)械化及這些婦女閑暇時(shí)間的增加并無多大聯(lián)系，更多地是與婦女自身的經(jīng)濟(jì)需要和高婚姻率相關(guān)。高婚姻率致使所能雇傭的單身女工的總量縮減，而在此之前的許多情形中，單身女性則是雇主們所愿雇傭的唯一—一類婦女。The pool of 如果后面跟著一群人，則表示勞動(dòng)力資源
難句類型：復(fù)雜修飾、插入語
解釋：主語the increase之后照例來了一堆修飾成分。后面的had less to do with…than do with…的意思是與前面的東西的關(guān)系不如與后面的關(guān)系那么重要，相當(dāng)于中文的與其說還不如說…。但是本句的比較雙方都是又臭又長(zhǎng)的由and所連接的兩個(gè)名詞性短語，令讀者閱讀時(shí)的思維難以連貫。The pool of如果后面跟著一種人群，則這個(gè)詞組指勞動(dòng)力資源。
意群訓(xùn)練：The increase in the numbers of married women employed outside the home in the twentieth century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers，previously，in many cases，the only women employers would hire.
