The late zoologist Sidnic Manton acknowledged that arthropods一animals with jointed exoskeletons, such as flies, crabs, and spiders- are all descended from soft-bodied segmented worms. Yet he maintained that differences in limb form, musculature, and embryonic development indicate that these three arthropod groups一insects. crustaceans. and chelicerates, respectively- evolved independently from worms rather than from i common arthropod ancestor. Consequently. according to Manton. shared characteristics such as a jointed exoskeleton and large compound eyes represent cases of convergent evolution- similar yet independent developments in these organisms. But if they evolved convergently, then one would expect significant differences in the neurological systems supporting sight. In fact. however. many nerve cells play virtually identical roles in supporting complex visual responses in both insects and crustaceans, suggesting that their common ancestor already possessed highly developed eyes, and therefore was probably already in arthropod. Yet the compound eyes of chelicerates differ neurologically from those of insects and crustaceans. suggesting that the eyes of chelicerata did evolve independently and providing partial confirmation of Manton's views.

It can be inferred that the author of the passage and Manton would be most likely to disagree over which of the following claims?

A. Insects and crustaceans are both descended from segmented worms. B. Insects and crustaceans each have unique limb form. Musculature and embryonic development. C. The compound eyes of insects and crustaceans are a case of convergent evolution. D. None of the characteristics common to insects and crustaceans can be found in segmented worms. E. Insects and crustaceans are the most closely related of all the arthropod groups.

第二题：推断题。M的观点是：昆虫和甲壳类动物的jointed exoskeleton and large compound eyes代表了趋同进化的例子——这些生物体中类似但独立的发展；也就是说M认为这昆虫和甲壳类之间有一定的联系；但是作者认为：如果是趋同进化，那么视力神经系统会有差异，但是他们发挥的作用是一致的。因此，可以推断，作者和M关于“the most closely related of all the arthropod groups.”的看法并不一致，对应E选项。 A错误，第一句话说M承认确实是soft-bodied segmented worms的后代，与作者看法一致。 B错误，unique limb form Musculature and embryonic development是M的看法。 C错误，文章第三句话中提到compound eyes是趋同进化；而作者最后也用chelicerates的例子证明了M的观点，所以他们的看法是一致的。 D错误，None of the characteristics common与文章相反，第二句中提到是有共同特征的。

disagree over 作者和M有分歧。C M认为这是convergent evolution，作者则反驳了M的这个观点。（首先找到M的观点，其次找到作者的观点）

disagree over就是有分歧的意思吧

这题张巍答案选C。解析：注意本题问的是作者和Manton的不同点，由第三句可知Manton认为large compound eyes是convergent evolution的结果；但是随后第四、五句作者对此进行了反驳（此处可参考第一题的解析），作者认为这并非是convergent evolution的结果，所以这是作者与Manton的不同点，C选项正确。BDE这三个选项并非二者的不同点，直接排除。本题有一个干扰选项A（选A的理由是第二句Manton提到Insects and crustaceans是由segment worms进化而来，而第五句作者认为Insects and crustaceans是arthropod的后代，所以认为A选项是二者的不同点），括号里面的分析没错，但这却忽略了第一句中的内容：arthropods是segmented worms的后代；也就是说无论是作者还是Manton，他们都认为Insects and crustaceans是segmented worms的后代（可以这样理解：Manton认为segmented worms→Insects and crustaceans；作者认为segmented worms→arthropod→Insects and crustaceans），所以A选项是二者的共同点，而非不同点。
