Question

【题目】— What’s the matter?

—I am having trouble __________ who has taken my book.

A. finding B. finding out

C. looking for D. looking up

Answer 1

【答案】B

【解析】

试题分析：句意：-怎么啦？-我很难找到谁拿走了我的书。Finding找到； finding out搞清楚，弄明白；looking for寻找； looking up在词典参考书中查找。 have trouble doing sth做某事有麻烦，所以选B。
