—Which of the two magazines will you take?
—I’ll take though I find of them are very useful to me.
- A.all;both
- B.either; either
- C.either; neither
- D.either; both
答案
正确答案:D
知识点:不定代词

根据前句two magazines可知,故排除A,因为all是指三者或三者以上都;所以第一个空是
either,两者中的任意一个,即“两本杂志中任一本”;又由though判断,后句是肯定的含义,且谓语是复数,所以both(表示两个都,表肯定)最合适。所以答案选D。
