What…? Which…? How…?/의문사

WHAT...? WHICH...? HOW...?
A. We usually make questions by changing the word order: we put the first
auxiliary verb (AV) before the subject (S):
Tom will -> will Tom?
* Will Tom be here tomorrow?
you have -> have you?
* Have you been working hard?
I can -> can I?
* What can I do? (not 'What I can do?')
the house was -> was the house?
*When was the house built? (not 'When was built the house?')
B. In present simple questions, we use do/does:
you live -> do you live?
* Do you live near here?
the film begins -> does the film begin?
* What time does the film begin? (not 'What time begins ...?')
In past simple questions, we use did:
you sold -> did you sell?
· Did you sell your car?
the accident happened -> did the accident happen?
· How did the accident happen?
But do not use do/does/did in questions if who/what/which is the subject of the
sentence. Compare:
who object
Emma telephoned _somebody._(object)
C.Note the position of prepositions in questions beginning
Who/What/Which/Where ...?:
* Who do you want to speak to?
* What was the weather like yesterday?
* Which job has Jane applied for?
* Where do you come from?
D. Negative questions (isn't it ...?/didn't you ...?)
We use negative questions especially to show surprise:
* Didn't you hear the bell? I rang it four times.
or when we expect the listener to agree with us:
* 'Haven't we met somewhere before 'Yes, I think we have.'
* Isn't it a beautiful day! (= It's a beautiful day, isn't it?)
Note the meaning of yes and no in answers to negative questions:
Don't you want to go to the party? Yes. (=Yes, I want to go)
