Using subject and object questions

Who ate my chocolates?There are two main types of question in English.

Subject Questions: You want to know who/what does something.

??? ate my chocolates?

Who ate my chocolates?

Object Questions: You want to know what someone did or who they did it to.

Jo ate ???

What did Jo eat?

Making subject questions

Subject questions are easy to make. You just use who or what instead of the subject of the sentence.

Who's meeting you at the station? (answer: My sister is meeting me)

Making object questions

Object questions need an auxiliary verb (do, be, have ...) before the subject, and a main verb (do, doing, done ...) after it.

Who were you talking to yesterday? (answer: I was talking to my boss)

Questions with when, where, why and other question words (what time, how long, how many ...) work in the same way as object questions.
