A B C D

1. D
- Lỗi sai: was giving => gave

“and” nối động từ “praised” (tán dương) và động từ “give” nên động từ “give” cũng phải ở dạng V2/ed.
- Câu hoàn chỉnh: The city leader praised the young people for following Uncle Ho's teachings, and gave them the awards.
(Lãnh đạo thành phố biểu dương các thanh niên làm theo lời dạy của Bác và tặng bằng khen.)
Chọn D
2. A

Dấu hiệu nhận biết thì quá khứ tiếp diễn “at 8 p.m. yesterday” (lúc 8h tối qua)=> Cấu trúc thì quá khứ tiếp diễn chủ ngữ số nhiều: S + were + V-ing.

- Lỗi sai: was getting => got
- Giải thích:
“and” nối các động từ ở dạng V2/ed gồm động từ “stopped” (dừng lại) và động từ “stood” (đứng dậy) và động từ “said” (nói) nên động từ “get” cũng phải ở dạng V2/ed.
- Câu hoàn chỉnh: When the bus stopped, everyone quickly stood up, said goodbye to the driver, and got off the bus.

Chọn D
6. B
