题目

-Why did they help Mrs.Brown with her work?-Because she was_______
A.an old friend of them B.a good friend of theirs
C.one of their of them
D.the friend of them
求理由,

答案

B
英文里面说 “他们的一个朋友”用a good friend 【of theirs】,“他们【众多好朋友中的】一个（好朋友）”.这里的theirs指的是their friends他们（众多）的朋友.
而不用 a friend of them,用中文思维的直接翻译容易写成them,但英文这里不用宾格,所以要把后面是them的都排除,只能选B了.
类似还有“我的一个朋友”用she is a friend of mine而不是she is a friend of me
语言这东西习惯就好了,见多了下次就能记住了,就像你学中文一样.
