Where, when, why, how

1. Where, when, why and how are question words. We use them like this:

---> Where
We use Where to ask about places:
Where is Mike? He´s at home

---> When
We use When to ask about times and dates:
When will you phone? At six o´clock.

---> Why
We use Why to ask about the reason for something:
Why is Mary taking a taxi? Because her car isn´t working

---> How
We use how to ask "in what way?":
How did he get to Brighton? He wen by train.



We also use how to ask about people´s health or happiness:

Hello. how are you? I´m fine, thanks.


2. We form questions with where, when , why and how like this:

---> In questions with be, we put the subjects after be:

be+ subject

Why is Paul angry?
Where are they?
Why is he here?

---> In questions with an auxiliary verb (will, is, are, can, must, etc.), we put the subject after the auxiliary verb:

verb + subject + verb

Why are they leaving?
How will she get there?
When will you phone ?

--->In questions with a Present Simple or Past Simple verb, we put a form of do before the subject:

do + subject + verb

Where does she live?
Why did you phone the police?
Where did he live?
