Bai tap dap an cau hoi duoi

Câu hỏi đuôi có những nguyên tắc chính như sau:

- You don’t know me, do you?
2. Với động từ khiếm khuyết: can, could, may, might, will, shall, should…
ta dùng động từ khiếm khuyết (not) + Subject.
Ví dụ:
- She can sing, can’t she?
- She mightn’t come, might she?
3. Với những câu phát biểu ở thì hiện tại đơn, ta phải mượn trợ từ “Do” hoặc “Does).
Ví dụ 1: He sings well, doesn’t he?
Ví dụ 2: They sing well, don’t they?
Ví dụ 3: He doesn’t sing well, does he?
Ví dụ 4: They don’t sing well, do they?
4. Với những câu phát biểu ở thì quá khứ đơn, ta phải mượn trợ từ “Did” hoăc “Was”, “Were”.
Ví dụ 1: She sang well, didn’t she?
Ví dụ 2: She didn’t sing well, did she?
Ví dụ 3: They were handsome, weren’t they?
5. Với những câu phát biểu ở thì hiện tại hoàn thành, ta phải mượn trợ từ “have” hoặc “has”.
Ví dụ 1: She has done her homework, hasn’t she?
6. Với những câu phát biểu là thì quá khứ hoàn thành, ta phải mượn trợ từ “had”.
Ví dụ 1: She had done her homework, hadn’t she?
7. Các trường hợp đặc biệt khác:
Used to → didn’t
Ví dụ: She used to go for a walk, didn’t she?
Had better → hadn’t
Ví dụ: I had better do my exercise, hadn’t I?
Would rather → wouldn’t
Ví dụ: They would rather go out than stay at home, wouldn’t they?
