1. (A) has done → did

→ Giải thích:

- "Has done" là thì hiện tại hoàn thành (present perfect), nhưng "then listened" lại là thì quá khứ đơn (past simple).

- Hai hành động nối tiếp trong quá khứ nên phải dùng cùng thì quá khứ đơn.

2. (B) bought → were bought

→ Giải thích: Cần sử dụng thể bị động cho phù hợp nghĩa của câu: Một vài bông hoa đã được mua cho mẹ của anh ấy vào sinh nhật của bà ngày hôm qua.

3. (A) considers → is considered

→ Giải thích: Cần sử dụng thể bị động cho phù hợp nghĩa của câu: Harvard được coi là trường đại học lâu đời nhất ở Mỹ.

4. (C) when → while

→ Giải thích:

- "While" nhấn mạnh hai hành động xảy ra song song, cùng một lúc.

- Trong câu này, cả hai hành động "painting" và "cooking" đều đang diễn ra cùng lúc, nên dùng "while" là tự nhiên hơn.

5. (A) will be taken → will take

→ Giải thích: Cần sử dụng thể chủ động cho phù hợp nghĩa của câu: Chúng tôi sẽ làm một bài kiểm tra về nguồn năng lượng vào lúc 10 giờ sáng thứ Ba.

6. (A) will be put → will put

→ Giải thích: Cần sử dụng thể chủ động cho phù hợp nghĩa của câu: Họ sẽ lắp các tấm pin mặt trời ở sân sau vào thứ Bảy tới.

7. (C) must → must not

→ Giải thích: Cần sử dụng phủ định cho phù hợp nghĩa của câu: Hãy cẩn thận khi bạn đang đi trên đường. Bạn không được lái xe nhanh hoặc bất cẩn.

8. (B) see → saw

→ Giải thích: "Two days ago" chỉ thời điểm trong quá khứ, nên động từ phải chia ở quá khứ đơn → "saw".

9. (C) have → having

→ Giải thích: Sau "in spite of" phải dùng danh động từ (V-ing) → "having" thay vì "have".

10. (B) bigest → biggest

→ Giải thích: "Biggest" là dạng so sánh nhất của "big", nhưng cần gấp đôi "g" theo quy tắc → "biggest".
