Forming a question
Wh-questions are formed by moving the verb BE, and then adding the Wh- word. Here are some examples:
We use What is … like? to ask for a description of someone or something e.g. their appearance, or their character.
Don’t do this
When we are leaving? (No!)
You need to change we/are i.e. change the positions of the subject/verb.
When are we leaving? (Yes!)
Don’t confuse the different meanings of ‘like’.
(Hint: ‘like’ is near the front of the question)
(Hint: like is at the end of the question)
We are leaving = When are we leaving? = Add wh-question word
