Sometimes we answer a statement by asking for more information. Questions of this kind have a very simple structure.
Study the following examples.
‘Susie is quitting her job.’ ‘Why?’ (More natural than ‘Why is Susie quitting her job?’)
‘I’m not coming to the party.’ ‘Why?’ (More natural than ‘Why are you not coming to the party?’)
‘Alice is getting married.’ ‘When?’(More natural than ‘When is Alice getting married?’)
‘The principal wants to see you.’ ‘What for?’(More natural than ‘For what does the principal want to see me?’)
‘The trains aren’t running?’ ‘Why not?’(More natural than ‘Why aren’t the trains running?’)
We can convert a negative statement into a question in two different ways.
Compare the example given below.
