Question

【题目】The policeman came in and asked__________.

A.where was the thiefB.how did he catch the thief

C.who is the thiefD.if the boss knew the thief

Answer 1

【答案】D

【解析】

句意：警察进来问老板是否认识那个小偷。

考查宾语从句。设空处做ask（问）的宾语，是宾语从句；宾语从句需用陈述句语序，ABC三项都是疑问句语序，可排除。宾语从句遵循主过从过原则，D项是陈述句语序，动词knew（知道）是过去式；根据句意结构，故选D。
