Question

【题目】---Do you know how long ________? ----I’m sorry I don’t know.

A. he has come here

B. has he been married

C. Tom has bought the car

D. his uncle has been abroad

Answer 1

【答案】D

【解析】

试题分析：句意：—你知道他的叔叔出国多长时间了？—对不起，我不知道。根据句意及题干分析此题是考查宾语从句，其语序是陈述语序，排除B；how long是时间段，和时间段连用句中的谓语动词要用延续性动作动词，而A、C句中的动词都是短暂性动作动词，故选D。
