句型与疑难结构|when和whattime对时间提问的区别

What time is it by your watch?
Do you have the time?
Can you tell the time?

Have you got the time? (熟人间问 )
May I trouble you to tell me the time? (客气地问 )
2 when 和what time 都可以引导特殊疑问句,对时间提问。when 可以问钟点、日期、月份、年份等,但不能问某年、某月、某日、某上午、下午、晚上等某个具体时刻、钟点。what time用来问钟点或问某事在某个具体时间发生。回答when引导的问句,不需要说出具体时刻,而回答what time引导的问句,必须说出具体时刻。

A: When were you born? 你什么时候出生的 ?(问日期、月份、年份不用what time)
