Trả lời:

1. Ta có cấu trúc câu hỏi đuôi chung S + had + PII, hadn’t S?

`=>` You had had breakfast before went to school yesterday, hadn't you ?

2. You could ride a bicycle when you were five couldn’t you ?

3. Ta có cấu trúc: There has/have been ……. , hasn’t/haven’t there?

 `=>` There have been many achievements since the country carried out economic reforms, haven't there ?

4. "The English" (người Anh), là danh từ số nhiều nên thay thế bằng "they" trong câu hỏi đuôi.
Ta có cấu trúc chung: S + V(hiện tại đơn), don’t/doesn’t S?
The English like watching football, don't they?

 1. You had had breakfast before went to school yesterday, hadn't you?(phủ định của quá khứ hoàn thành )

2. You could ride a bicycle when you were five ,couldn't you ?( trong câu láy đuôi đối với đông từ khuyết thiếu could ta đổi thành couldnt)

3.There have been many achievements since the country carried out economic reforms, haven't there ?(phủ định của hiện tại hoàn thành)

4. The English like watching football, don't they?(LIKE GIỮ NGUYÊN => THE ENGLISH LÀ SỐ NHIỀU VÌ THẾ TA DÙNG DONT THEY)
