文章講解：

①M(fèi)ost mammals reach sexual maturity when their growth rates are in decline,?whereas?humans experience a growth spurt during adolescence. ②Whether apes experience anadolescent growth spurt is still undecided. ③In the 1950s, data on captive chimpanzees collected by James Gavan appeared devoid of evidence of an adolescent growth spurt in these apes. ④In a recent reanalysis of Gavan’s data,?however, zoologist Elizabeth Watts has found that as chimpanzees reach sexual maturity, the growth rate of their limbs accelerates. ⑤Most biologists,?however, are skeptical that this is a humanlike adolescent growth spurt. ⑥While the human adolescent growth spurt is physically obvious and affects virtually the entire body, the chimpanzee’s increased growth rate is detectable only through sophisticated mathematical analysis. ⑦M(jìn)oreover, according to scientist Holly Smith, the growth rate increase in chimpanzees begins when 86% of full skeletal growth has been attained, whereas human adolescence generally commences when 77 percent of full skeletal growth has occurred.?

題型講解：

1. Which of the following best describes the main idea of the passage??主旨內(nèi)容題

A.?Researchers?have long disagreed about whether data collected in the 1950s indicate that chimpanzees and other apes experience an adolescent growth spurt. 好像來自④。沒有證據(jù)，只提到一個(gè)Watts對數(shù)據(jù)的研究；或無關(guān)，以偏概全，是個(gè)細(xì)節(jié)，與文章整體無關(guān)

B. Research data collected on chimpanzees living in captivity are inconclusive with respect to chimpanzees living?in the wild.?沒有證據(jù)

C. The notion that apes do not experience an adolescent growth spurt has been confirmed by research conducted?since.?相反，后文有用四肢生長率的證據(jù)反轉(zhuǎn)

D. Although the idea that apesexperience an adolescent growth has received some support, most biologists remain unconvinced.?符合

E. Although researchers?agree?that chimpanzees do not experience an adolescent growth spurt, they are divided in their opinions of whether this is true of?other apes. 相反/沒有證據(jù)

2. The passage?mentions?which of the following as one of the reasons why?most biologists?remain skeptical that chimpanzees experience a humanlike adolescent growth spurt? 直接細(xì)節(jié)題，定位⑤，答案⑥⑦

A. Chimpanzees do not experience a demonstrable increase in growth rate?until?they are fully sexually mature. 黑猩猩直到完全性成熟才猛增，沒有until的證據(jù)，打相反也可以。

B. The increase in growth rate that chimpanzees undergo at sexual maturity is less apparent than that of humans. 對應(yīng)⑥

C. The increase in growth rate once regarded as a humanlike adolescent growth spurt in chimpanzees is too?sporadic?[張1]??to be regarded as significant.?沒有證據(jù)

?[張1]散亂，零星

D. Not all chimpanzees undergo a calculable growth spurt.?NE/RE

E. Watt’s?approach?to analyzing data is considered to be highly?unorthodox[劍2]?. 沒有證據(jù)，并沒有提到Watts的研究方法，也不知道正統(tǒng)的方法是啥樣

?

3. The passage?suggests?which of the following about the adolescent growth spurt that takes place in humans??細(xì)節(jié)推斷

A. Its primary effects are found in parts of the body other than the limbs.?相反，影響全身

B. It is generally?completed?by the time 77 percent of full skeletal growth is attained.?相反

C. It is normally detectable without the assistance of sophisticated mathematical analysis.對應(yīng)⑥直接對比取反

D. The rate of growth is?much faster?at the beginning of puberty?[劍3]?than at any other time.?沒有證據(jù)

[劍3]['pjub?ti]青春期

E. The estimated growth rate varies depending on the?methods?of measurement that are used.?沒有證據(jù)
