Whenwhat time你区别了吗?

同学们应该都知道 whenwhat time都可以用来对时间提问,那么它们的用法到底有什么区别呢?为解开同学们的疑惑,下面小编就将其具体用法的区别归纳如下:

一、 what time常用来问钟点,而 when除了问钟点外,还可用来问日期,月份,年份等。有时两者可以换用,但有时则不行,如:

1.当问钟点时,可以换用。

When do you go to school? 你何时去上学?

What time do you go to school? 你几点去上学?

2.当问日期、月份、年份等,只能用 when

- - - When were you born? 你何时出生?

- - - I was born on July 2,1972. 我生于 197272日。

3.当问某事在某天的什么具体时间进行,只能用 what time

- - - What time did you call this afternoon? 你今天下午几点打过电话?

- - - I called at 4:00 this afternoon. 我下午四点打的。

注意:虽然有时 whenwhat time可以互换,但是从上可知:对 when的回答可以是一个具体时间,也可以不是一个具体时间(如: in the morning, last year, in 1998等范围大的时间);而对 what time的回答只能是一个具体的时间,一般落实到小时。试对比以下例句:

- - - When does he take a shower? 他什么时候洗澡?

- - - He takes a shower in the morning. 他在早上洗澡。

也可用具体时间: He takes a shower at 6 o'clock in the morning. 他早上六点洗澡。

二、 when的用法比 what time亦复杂得多,下面对其一一讲解。

1. when作为副词时

a.(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?

b.(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.

2. when作为连接词时

a.当时

John got engaged to her when travelling last winter.

Don't get excited when you talk.

b.既然,考虑到

How can he get the promotion when his boss dislikes him?

c.虽然,然而

I had only fifteen dollars on me when the book I wanted cost twenty.

3. when作为代词时

Since when has she taught here?(什么时候,那是)

通过以上分析后,我相信同学们都能够准确地区分 whenwhat time了吧!
