when与what time询问时间有何讲究?

when与what time都可以用来询问时间,意为“什么时候”,但它们并不完全等同。在不同的语境下,它们的使用还是有一定讲究的,也就是说,它们有时可以互换,有时却不能。具体用法如下:
一、询问做某事的时间(钟点)时,两者可以互相替换。例如:
-When / What time do you go to school?
你什么时候去上学?
-I go to school at seven o’clock.
我七点钟去上学。
二、询问钟表所表示的具体时间(钟点)时,只能用what time, 而不能用when。例如:
-What time is it now, Jack? 杰克,现在几点了?
-It’s eight thirty. 八点半。
三、询问事件发生的年份、月份、日期等非钟点性时间时,只能用when, 而不能用what time。例如:

1. -When was your brother born?
你弟弟什么时候出生的?
-In 1995. 1995年。
2. -When is Teachers’ Day?
教师节是哪一天?
-It’s September 10th. 九月十日。
