Question

【题目】--- Could you tell me ?

--- Certainly. In 20 minutes.

A. when will the train to Beijing leave B. when the train to Beijing would leave

C. when the train to Beijing left D. when the train to Beijing will leave

Answer 1

【答案】D

【解析】句意：——你能告诉我去北京的火车什么时候开吗？——当然可以。再过20分钟。考查宾语从句。宾语从句需用陈述句语序，A是疑问句语序，可排除。根据In 20 minutes（20分钟后）可知，车还没有开，需用一般将来时，即will+原形动词结构，故选D。
