150. (32705-!-item-!-188;#058&007266)

Hydrocarbons, with which fruit flies perfume themselves in species-specific blends, are known to be important in courtship, and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of others.

(A) and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of

(B) and apparently this assists flies when they taste the hydrocarbons on prospective mates in distinguishing their own species from those of

(C) which apparently assists flies that taste the hydrocarbons on prospective mates in being able to distinguish their own species from

(D) apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of

(E) apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from

这里面我不明白的是those of为什么可以不要？是因为从句意上“它们的物种”就等于它们？

distinguish A from B

those of指代什么呢?species of others?好像不对的哦，所以E

D的问题如下:

1. taste the hydrocarbons是flies的定语.to taste the hydrocarbons能不能成为flies的定语我不清楚,不过起码会造成歧义,让人认为to taste the hydrocarbons是assisting的状语;

2. 我认为把those of去掉有两种解释:

A. others是名词性物主代词.those of应该就可以省略了.比如说,I dropped his wallet but not mine.就不用I dropped his wallet but not that of mine了.

B. others是代词,指其他物种.再用those of就意思重复了.

个人比较偏向于others作为代词指代其他物种.

嗯，我刚在网上查到一种说法，others= “other +名词”。代词，泛指。后面不能再接名词了。
就是说不存在others’物种的说法。

其实和msuzengli兄说的差不多。总之以后要记住others就什么都没有了。不存在什么those of others
