THEME:Past simple and be: question & negative forms

For negatives and questions in the past simple tense, we use the auxiliary verb did — the past of "do". Compare: I don't like tomatoes. → I didn't like tomatoes. Do you live in London? → Did you live in London? did + not = didn't In the negative sentences, we normally use the short word "didn't" instead of "did not". If there is an auxiliary verb, it takes over the indication of the tense. The main verb comes in its infinitive form. In the negative and question sentences in the past simple, "did" takes over the tense, exactly like "does" in the present simple.
