正确的说：When是指：什么时候。而What time 是指什么时间。
When:
一,副词 ad.
1.(用作疑问副词)什么时候,何时
I'd like to know when they'll let him out.
When did you last see Margaret?
2.(用作关系副词,引导关系从句)当...时
There were times when I didn't know what to do.
二,连接词 conj.
1.当...时
John got engaged to her when travelling last winter.
Don't get excited when you talk.
2.既然,考虑到
How can he get the promotion when his boss dislikes him?
3.虽然,然而
I had only fifteen dollars on me when the book I wanted cost twenty.
4.在那时,然后
三,代词 pron.
1.什么时候,那时
Since when has she taught here?
四,名词 n.
1.(事件发生的)时间[the S]
What time:
什么时间 问具体时间，如几点钟
例: What time is it now?
What time is suitable for us to meet?
What time 常用来对某个具体时间点进行提问。
what time是具体的问法
回答是时刻
WHEN能代替WHAT TIME
但WHAT TIME不能代替WHEN
UNDERSTAND？
when 不能用于完成时
what time 可以
when 可作系动词,表某段时间,what time不行>>>>
