4. 对状语部分提问

用特殊疑问词 when, what time, where, how, why 等引导，后加一般疑问句形式。例如：

1) I often go to schoolin the morning. (问时间，状语)

→What time do you often go to school in the morning?

2) We have lunch . (问地点，状语)

→Where do you have lunch?

3) My sister goes to school . (问方式，状语)

 →How does your sister go to school?

4) Mary didn’t come to school yesterday . (问原因，状语)

→Why didn’t Mary come to school yesterday?

注：how long, how soon和how often都含有“多久”的意思，都能对时间状语进行提问，应注意其区别：

how long提问“一段时间”，即对介词短语for... 和since... 提问，可用于一般现在时、一般过去时、一般将来时、现在完成时等。如：

They stayed there . (问多长时间，状语)

→How long did they stay there?

how soon提问“多久以后”，即表示所间隔的时间段，如介词短语in... 等，常与一般将来时连用，这种情况有时也可用when提问。如：

He will be back . (问多久以后，状语)

→How soon／When will he be back?

They will finish the work . (问多久以后，状语)

→How soon will they finish the work?

how often提问频度、“多久一次”，即重复动作所发生的时间间隔，不强调次数，常与一般现在时和一般过去时连用。如：

I watch TV . (问多久一次，状语)

→How often do you watch TV？
