What time？

涂于德

“What time do you work out every morning?” is a common sentence.

However, someone asks me a question:
Why should “What time” not be changed into “At what time”?

I don't think we can say like "at what time". If never we need to precise the time, I think maybe we should say "at which o'clock",if it is right.............................

For example,
  -----What time do you get up in the morning?
  -----I get up at 6.00 a.m.

Why is it that the answer "at 6.00 a.m." is "at what time", yet the question is "what time"?

特殊疑问句都是以疑问词开头的呀？除了在从句中，还有没有“介词+疑问词”的例句？

Here,

In which lecture hall did you have the lecture?

I give up answer your question in English.

我想这个介词at只是引导了一个普通时间概念的时间状语，尽管连接了一个特定的时间。对于这样一个介词+时间的普通时间概念性质的整体时间提问，那么我想应该说什么时间what time。但是如果想对确切的时间提问，那么我想应该对特定的钟点提问，在这样的条件下，那么这个介词at已经不属于提问对象之内，因此应该表达成在几点at which o'clock.
我只是从中文以及另外一种语言的提问方式照样画葫芦而已。

是呀，糊涂了

有这样的例子：

I arrived on Thursday morning.

At exactly what time?

那么，这样用应该没问题呀

但不管怎么说，这是一种较少见的用法，所谓marked or deviated, 可以视为表示强调吧？
也就是说要对方回答得比通常更具体。
