Question

【题目】I noticed them ______ the tall building just now.

A. went into B. go into

C. was going into D. came out of

Answer 1

【答案】B

【解析】

句意：我注意到他们刚才进了这栋高楼。考查非谓语动词的用法。A. went into进入，过去时；B. go into进入，动词原形；C. was going into正在进入；D. came out of出来。注意到某人做过某事的短语是 notice sb. do sth.，注意到某人正在做某事，notice sb. doing sth.。因此A/C/D都不对。故选B。
