Question

【题目】—How long has the son ____________?

— For six months. His parents miss him so much.

A. left home B. joined the army C. gone abroad D. been away

Answer 1

【答案】D

【解析】句意：——那个儿子离开了多长时间？——六个月。他的父母非常想念他。left home 离开家，是瞬间性动词；joined the army参军，是瞬间性动词； gone abroad 出国，是瞬间性动词；been away离开，是延续性动词。根据How long可知与时间段连用，用延续性动词，故选D。
