Question

【题目】Helen here since she was 5 years old．

A. has come B. came C. has gone D. has been

Answer 1

【答案】D

【解析】句意：海伦自从五岁就来这里了。since she was 5 years old表示从过去开始持续到现在的一段时间，主句应该用现在完成时；come是非延续性动词，要表示“来这里多长时间”．不能用have come here+时间，需要改为相应的延续性动词短语be here；be的现在完成式为have／has been;have gone to表示“去了”，不符合题意。故选D。
