When and What time?这两个词我搞不太懂啊,各应该用在什么地方啊?Our class begins at 9;00.I go to the park every day.I do my home work at night.这是三个回答,那它们的问题用什么呢?

when和what time都是差不多的

when指什么时候，例：When did you go yesterday？
时间疑问词。
what time指几点。例：What time is it？
when does your class begin？
how often do you goto the park？
when do you finish your homework？

When要比What time范围更大些,what time 是问某具体的时间点
解答如下:
1,What time does your class begin at?
Our class begins at 9;00.
2,How often do you go to the park?
I go to the park every day.
3,When do you do your homework?
I do my home work at night.

when 和 what time 从意思理解上是一样的
区别在于when不仅可以修饰一个时间点，还可以修饰一个时间段（比如说一年
）
但是what time 就只能修饰某一个具体的时刻
所以第一句用what time/when 都可以
而第二，三句只能用when 提问

一般来说,when和what time都是差不多的
When/What time does your class begin?
When/What time do you go to the park?
When/What time do you do your homework?

两词有区别:
when用于大体概念时间的一个疑问词,如某天某月,大约某个时间段(左右)
what用于精确的时间概念,某一确定的时刻
依照这些相信你能解决上述问题

1.what time does your class begin?
2,how often do you go to the park?
3,when do you do your homework?
涉及具体几点钟时用“what time”, 大范围的时间如日，月，年用“when”,表示频率时用how often,多长时间用how long,多快，多久（将会怎样）用how soon
