4、d ancestor we shared in common with living chimpanzees - to walk on two legs. 我們大多數(shù)人每天都走路而且手里搬著東西。這樣的活動看似太簡單，大多數(shù)人沒有疑問。但是一個國際研究者（包括喬治o華盛頓大學(xué)哥倫比亞藝術(shù)與科學(xué)學(xué)院的Richmond博士）團隊已經(jīng)發(fā)現(xiàn)了人類直立行走可能源于數(shù)百萬年以前適應(yīng)搬運稀有的、高質(zhì)量的資源。這些來自美國、英國、日本和葡萄牙的研究者研究了當(dāng)代黑猩猩爭搶食物時的行為特征，試圖對什么樣的生態(tài)環(huán)境竟然導(dǎo)致大猿（一種我們與現(xiàn)存的黑猩猩一樣的600萬年前的祖先）直立行走作出解釋。 "T

5、hese chimpanzees provide a model of the ecological conditions under which our earliest ancestors might have begun walking on two legs, "said Dr. Richmond. "這些黑猩猩居住的生態(tài)環(huán)境和我們最早的祖先開始直立行走時是相同的，" Richmond博士說。 The research findings suggest that chimpanzees switch to moving on two limbs instead of four

6、in situations where they need to monopolize a resource. Standing on two legs allows them to carry much more at one time because it frees up their hands. Over time, intense bursts of bipedal activity may have led to anatomical changes that in turn became the subject of natural selection where competi

7、tion for food or other resources was strong. 研究結(jié)果顯示，當(dāng)黑猩猩需要獨占一種資源時，它們就從四肢行走轉(zhuǎn)換為直立行走。由于直立行走可以解放它們的雙手，這使得它們能搬更多的東西。久而久之，雙足活動的強烈爆發(fā)可能導(dǎo)致了解剖學(xué)上的變化，因此這種變化也就成為自然選擇的主題，在那種情況下，對食物或其他 資源的爭奪是十分激烈的。 Two studies were conducted by the team in Guinea. The first study was conducted by the teamin Kyoto Universit

8、ys "outdoor laboratory" in a natural clearing in Bossou Forest. Researchersallowed the wild chimpanzees access to different combinations of two different types of nut—the oil palm nut, which is naturally widely available, and the coula nut, which is not. The chimpanzees" behavior was monitored in th

9、ree situations: (a) when only oil palm nuts were available, (b) when a small number of copula nuts were available, and (c) when coula nuts were the majority available resource. 有兩項研究是在幾內(nèi)亞完成的。第一項研究是在京都大學(xué)博蘇森林的一塊天然空地--"室外實驗室"進行的。研究者們允許森林里的黑猩猩能得到兩種不同的堅果，一種叫油棕櫚堅果，自然界隨處可見，一種叫可樂果，自然環(huán)境中不常見。人們監(jiān)控黑猩猩在下列三種情形下的

10、行為：(a)只有油棕櫚堅果；（b)只有少量的可樂果，大多數(shù)是油棕櫚堅果;(c)大多數(shù)是可樂果，少數(shù)是油棕櫚堅果。 When the rare coula nuts were available only in small numbers, the chimpanzees transported more at one time. Similarly, when coula nuts were the majority resource, the chimpanzees ignored the oil palm nuts altogether. The chimpanzees rega

11、rded the coula nuts as a more highly-prized resource and competed for themmore intensely. 當(dāng)稀有的可樂果數(shù)量很少時，黑猩猩一次就會拿得多。同樣，當(dāng)大部分是可樂果時，黑猩猩對油棕櫚堅果根本視而不見。黑猩猩認(rèn)為可樂果才是珍貴的資源，并為得到可樂果激烈競爭。 In such high-competition settings, the frequency of cases in which the chimpanzees started moving on two legs increased

12、by a factor of four. Not only was it obvious that bipedal movement allowed them to carry more of this precious resource ,but also that they were actively trying to move as much as they could in one go by using everything available - even their mouths. 處于這種激烈競爭的環(huán)境中，黑猩猩直立行走的頻率增加了四倍。很顯然，雙足行走可以使它們拿走更多的

13、稀有資源，而且，為了盡可能地一口氣多拿，它們積極利用可用到的任何方法，甚至嘴巴。 The second study, by Kimberley Hockings of Oxford Brookes University", was a 14-monthstudy of Bossou chimpanzees crop-raiding, a situation in which they have to compete for rate andunpredictable resources. Here, 35 percent of the chimpanzees activity invol

14、ved some sort of bipedal movement, and once again, this behavior appeared to be linked to a clear attempt to carry as much as possible at one time. 第二項研究是在牛津布魯克斯大學(xué)的Kimberley Hockings進行的。該研究歷時14個月，主題是博蘇的黑猩猩搶劫糧食，場景是它們不得不為稀有和不可預(yù)知的資源競爭。在這項研究中，黑猩猩35%的活動是直立行走。而這一次研究再一次證實了黑猩猩的直立行走與它們試圖一次搬走盡可能多的東西有關(guān)。 練習(xí)：

15、 1. Which of the following statements is NOT true according to the first two paragraphs? 根據(jù)前可段，下例那一個不對！ A Many people question the simple human activities of walking and carrying items.

Why did the chimpanzees walk on two limbs during Kyoto Universitys experiment? 在京都大學(xué)的試驗中黑猩猩為什么直立行走？ 　A Because they imitated模仿the human way of walking just for fun. 　B Because they wanted to please the researc

19、hers to get more coula nuts from them. 　C Because they wanted to get to the nut-rich forest faster by walking that way. 　D Because they wanted to carry more nuts with two free limbs. 5. What can we infer推斷from the reading passage? 從本文中可以推斷出什么？ 　A Chimpanzees are in the same process of evoluti

20、on as our ancestors were. 　B Chimpanzees are similar to humans in many behaviors. 　C Walking on two limbs and walking on four limbs each have their advantages. 　D Human walking on two legs developed as a means of survival. 答案與題解： 1.A 第一段第一句和第二句說明，大多數(shù)人對人類直立行走習(xí)以為常，并不質(zhì)疑這種習(xí)慣。而A 的內(nèi)容正好與此相反，所以是答案。其他

21、選項所述內(nèi)容均可從第一段和第二段推斷出來. 2.B 文章報道，科學(xué)家通過實驗證實黑猩猩直立行走是為了解放前肢，讓前肢搬運對其生命至關(guān)重要的資源，從而推斷出人類祖先也經(jīng)歷了從四足到二足的進化過程?？茖W(xué)家想通過對黑猩猩的實驗解釋人類直立行走的成因。所以B 是答案，A 、C、D 選項不是科學(xué)家進行研究的目的。 3. C 第五段明白無誤地描述了黑猩猩全然不顧油棕櫚堅果(ignored the oil palm nuts altogether ) ，集中精力搶運可樂果。所以C 是答案，B 、C 、D 的內(nèi)容不符合文章原意。 4.D 黑猩猩用后肢直立行走，搬運資源的效率提高了四倍。選項D

22、 符合原意，是答案。選項A、B 、C 的內(nèi)容文章中沒有提到，所以不是答案。 5. D 了解了通篇文章的意思，就會選擇選項D，人類直立行走是受生態(tài)環(huán)境所迫，是人類生存的一種手段.直立行走是自然選擇的結(jié)果。選項A 和C 的內(nèi)容文章中沒有涉及. 文章中有選項B 的內(nèi)容，但它不是文章的主旨。 第四十八篇 Researchers Discover Why Humans Began Walking Upright 　　Most of us walk and carry items in our hands every day.

43、 Belchers team includes Paula Hammond，who helps put together the tiny batteries, and Yet-Ming Chiang， an expert on how to store energy in the form of a battery．“We’re working on things we traditionally don’t associate with nature．” says Hammond． 貝爾徹的團隊包括幫助組裝微型電池的寶拉哈蒙德和以電池形式存儲能量的專家蔣業(yè)明。哈蒙德

44、說，“我們現(xiàn)在從事的行業(yè)是傳統(tǒng)中不會想到的?！?

53、、感冒和艾滋病，所以人們想盡辦法躲避病毒。這是C所表達的意思。A不是正確選擇，因為文章并沒有說人們想方設(shè)法去殺死病毒。B的后半句的內(nèi)容(病毒肉眼看不見)和D的內(nèi)容(吃藥治療病毒引起的疾病)文中沒有提到. 2．C短文的第二段明確提供了答案。 3．D 根據(jù)上下文，shrink在此的意思是“收縮”，即“縮小”。所以，它的反義詞是expand(增大，擴張)。C不是正確選擇，因為extend的意思是become longer，即“延伸”或“加長”。A的意思是“加寬”，也不是答案。B的意思是“伸展，展開”，在一定的上下文里也可以做shrink的反義詞，但在第五段這個語境里，B不是最佳選擇。 4．D

54、第六段第二句中提到的metallic disk是指“金屬圓盤”，它是微型電池的外形，其內(nèi)部是由病毒構(gòu)成的電池部件。微型電池不是由金屬組成的，所以A不是答案。本段提到，這種電池looks like a regular watch battery，與手表里電池外形相似，但并不等同手表電池，所以B也不是正確選擇。文章只是說電池的部件(但并沒有說整個電池)小到只能用顯微鏡才能看到，所以C也不是正確的選擇。D才是第六段所要表達的主要內(nèi)容，因此是答案。 5．A 短文最后一段的第四句(“you could probably fit about lo of these virus-built batter
