Questions in English use one of three auxiliary verbs: to be - to have - to do.
When learners form questions, the two most common mistakes are the wrong word order and the omission of the auxiliary verb. To avoid these common mistakes it's important to revise the basic question forms.
Types of question
Yes/ No questions: These questions have an answer with a yes or a no and are also a closed question.
- Are you on holiday?
- Have you been here long?
- Do you like chocolate?
Present and past simple yes/no questions
For all verbs except BE and HAVE, we use the auxiliary verb do/does or did to make yes/no questions.
- Did you visit Scotland in September?
- Do they work hard at school?
- Does he study a lot?
Wh-questions use the question words: what, when, which, who, whose, why and how.
- Where are they going?
- Why have you been working so hard?
- When did she arrive?
- Who is he seeing tomorrow?
- What are we doing for your birthday?
