  For more than fifty years, many evolutionary biologists posited that early

  fish such as Eusthenopteron developed limbs as a result of the need to drag

  themselves across short distances when their watery habitats dried up during

  periods of drought. However, new fossil evidence suggests that this hypothesis

  is incorrect. Fossilized remains of Acanthostega, a primitive fish, reveal that

  even though the animal had rudimentary limbs, it could not walk on land.

  Acanthostega lacked ankles, which means that its limbs couldn’t support its

  weight; furthermore, its ribs were too short to prevent 北美托福答案 the organism’s chest

  cavity from collapsing once the animal left water.

  1. Which of the following would most strengthen the author’s argument?

  A. The fossilized remains of the Acanthostega are the earliest known evidence

  of early fish.

  B. The modem descendants of Acanthostega are not able to drag themselves

  across short distances on land.

  C. Biologists have found that some aquatic species can successfully drag

  themselves across land even though these species do not possess ankles.

  D. Any animal with a collapsed chest cavity is not able to survive long

  enough to travel even a short distance across land.

  E. Some evolutionary biologists believe that the new fossils are not from

  Acanthostega.

  答案:D

  原文大意:许多生物学家假设很久以前的鱼长出四肢是为了在陆地上移动很小的距离,但是作者认为最新化石表明即使有四肢也无法在陆地上移动,一是因为没有脚踝不能支持身体重量,二是因为肋骨太短不能防止上岸后胸腔塌陷。

  解析:题干要求选出最可以支持作者结论的选项。我们可以发现作者的观点和第二个原因之间有逻辑漏洞,那就是胸腔塌陷是否一定会无法在路上移动,选项D填补了这个逻辑漏洞。
