| The intricate structure of the compound insect eye, having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it evolved independently of the vertebrate eye. (A) having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it (B) having hundreds of miniature eyes that are called ommatidia, helps explain why scientists have assumed that they (C) with its hundreds of miniature eyes that are called ommatidia, helps explain scientists’ assuming that they (D) with its hundreds of miniature eyes called ommatidia, help explain scientists’ assuming that it (E) with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it This sentence addresses why scientists have decided that the vertebrate eye and the insect eye evolved independently of each other. The insect eye is much more intricate, with hundreds of miniature eyes. The sentence needs to be clear as to what has hundreds of miniature eyes. The structure or the insect eye? Furthermore, the singular subject intricate structure requires the singular verb helps. A This wording misleadingly suggests that the intricate structure has miniature eyes, while the correct subject of the predicate having is the compound insect eye. Subject-verb agreement is violated. B This wording misleads as in (A). Furthermore, the pronoun at the end of the underlined part of the sentence should refer back to the compound insect eye, so it cannot be plural. C The phrase helps explain scientists’ assuming correctly agrees with the subject structure. However, it is nonstandard and awkward; the use of assuming with the possessive is unwarranted. Finally, the pronoun at the end of the underlined part of the sentence should refer back to the compound insect eye, so it cannot be plural. D The subject structure and the verb help do not agree in number. As in (C), explain scientists’ assuming is verbose and awkward, and the use of the assuming with the possessive makes the construction unnecessarily complex. E Correct. The phrase with its hundreds correctly refers back to the compound insect eye. The verb helps correctly agrees with the subject structure. Finally, the pronoun it correctly refers to the singular noun the compound insect eye. The correct answer is E. 我能理解A中的错误：因为现在分词短语放句尾并有逗号隔开的话，表示伴随/结果状语。这里应该理解为表伴随比较合适，但是这样一来have的动作发出者就成了strucuture,逻辑不通，故杀之。 但是E中的with的解释“The phrase with its hundreds correctly refers back to the compound insect eye.”我不是 很明白：为什么这个with结构就一定修饰the compund insect eye?我觉得这里有修饰对象不明确的问题，因为我觉得这个介词结构也可以修饰句子主语structure。关于这一点，求教？？？？？？？ 谢谢大神了！ |
