When Peter speaks in public, he always has trouble        _ the right things to say.

A.thinking of

B.to think of

C.thought of

D.think of

答案

A

题目分析:本题考查固定搭配,have trouble in doing sth.做…有困难,in可以省略,句意:当彼得在公共场所讲话时,他总是找不到适当的话说。所以答案为A。

点评:have trouble( in) doing sth. .做…有困难还可以用have difficulty (in) doing sth.学生可能由于固定搭配不清楚而出错。
