Questions and negatives
Quy tắc
Turning a statement into a question or a negative is a mechanical operation in English, and the mechanics are worth doing slowly until they are automatic.
Ghi nhớ
- Identify the helper: be, a modal, have in a perfect, or none.
- With no helper, insert do, does or did and return the verb to base form.
- A question word goes first, and the inversion happens behind it.
Bẫy thường gặp cần tránh
When the question word is the subject, there is no inversion and no do at all: who called you keeps statement order.
