(A) Unlike most warbler species, the male and female blue-winged warbler are very difficult to tell apart.

(B) Unlike most warbler species, the gender of the blue-winged warbler is very difficult to distinguish.

(C) Unlike those in most warbler species, the male and female blue-winged warblers are very difficult to distinguish.

(D) It is very difficult, unlike in most warbler species, to tell the male and female blue-winged warbler apart.（E）

(E) Blue-winged warblers are unlike most species of warbler in that it is very difficult to tell the male and female apart.

这道题选E，

我想问下比较对象是blue-winged warblers 和most species of warblers么？如果是的话，对象对等吗？一个是warblers ,一个是species啊？

请NN指教~~

答案: E

比较平行结构: 比较对象对等. 关键是分析这里究竟比较什么. 根据涵义, 发现比较的对象是区分male 和female的难易程度. 所以排除A, B, C.

逻辑表达:    D中unlike有歧义, 因为紧跟在difficult后面, 可能修饰difficult, 也可能修饰it.

C比较容易混淆, 其实those就是比较male 和female, 而没有突出是区分male 和female的难易程度;

而E中用了in that引导的从句, 强调了比较的对象是整个句子it is very difficult to tell the male and female apart.要说明的内容, 就是区分male 和female的难易程度. 所以很清楚.
