【题目】—Could you tell me ? —Certainly. In half an hour.

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 leaves

Answer 1

【答案】D

【解析】

试题分析：句意：----请你告诉我到北京的火车何时离开吗？---当然，半个小时之后。从句要用陈述句的语序。如果主句是一般现在时，从句根据需要选择时态。根据回答在半个小时之后，可知在问将来的时间。根据题意，故选D。
