(·浙江高考)No matter how bright a talker you are, there are times when its better silent.

A. remain

B. be remaining

C. having remained

D. to remain

答案：

A. remain

B. be remaining

C. having remained

(答案→)D. to remain

解析：选D考查非谓语动词。句意：不管你多么能言善辩，但有时候还是保持沉默更好。该题考查“it is＋形容词＋to do sth.”这一句型，句中to remain silent“保持沉默”是真正的主语，it是形式主语。
