做题时根本没有理解题意,还纠结assisting是修饰courtship(求爱),显然是在修饰HCBN。这句的错误: 1. assist in doing sth; 2. taste the HCBN 是修饰flies,而不是assist的状语,所以用that 定语从句更好,distinguish 是assist的状语,这里却更像修饰taste。

D is wrong because if we say "their own species from those of others" so those refers to species or technically to whole "their own species " or there are other errors in D. the original meaning is that hydrocarbons assist those flies that happen to taste them in species identification. - choice d asserts that hydrocarbons somehow help flies to taste hydrocarbons (other ones?) with the intention** of species identification, which is a whole different ballgame.

改变句意,不过这个句子也真是够难。

  D. assist习语搭配不正确;选项改变了原句的动宾关系:to taste作assist的宾语,to distinguish作taste的宾语,完全改变了句子意思;those没有指代对象,即使改为that,也不正确 assist (somebody) with/in something, assist in doing somethingwhich、this不能用于指代前句描述的事情 E对

句意来解释就是,D:这种物质帮助苍蝇去尝味,尝味是为了分辨别人。 E:这种物质帮助尝味的苍蝇去分辨别人。 1. 弄清楚比较对象,distinguish A and B. AB要平行。 区分自己和其他物种。如果加了those,变成those of others, others=other species,这里those也不能指代。而且species是单数,those也不能指代。
