GRAMMAR COMMENT [1, p.13]
Question formation. Indirect questions
· Use indirect questions when you want to ask a question in a more polite way.
Could you tell me where is the hospital located?
· You can use if or whether in ‘yes/no’ questions.
Could you tell me if /whether the government will rebuild the city?
· Questions ending in prepositions, short questions
If a verb is followed by a preposition it comes afterthe question, not before the question word.
What are you working on?
We often just use the question word and the preposition in a series of questions or when responding.A:I’m thinking? B:What about?
