Dưới đây là những lỗi sai và cách sửa cho từng câu:

8. **"let's stick a glass to it."** → **"let's stick a bandage to it."** (hoặc "let's put a glass on it.")
9. **"when we will finish our exams."** → **"when we finish our exams."** (không dùng 'will' trong mệnh đề thời gian)
10. **"used to giving me"** → **"used to give me"**
11. **"with her boyfriend"** → Sửa không cần thiết.
12. **"weather in the mountains, the climbers decided to cancel their climb."** → "weather in the mountains, the climbers decided to cancel." (sửa 'cancel to their climb' thành 'cancel')
13. **"is not an intelligent student"** → **"is not an intelligent student,"** (thêm dấu phẩy trước "but")
14. **"to stay at home because of he was sick."** → **"to stay at home because he was sick."** (Bỏ 'of')
15. **"the cheap price, my wife insists on buy the TV."** → **"the cheap price, my wife insists on buying the TV."**

Như vậy bản đã sửa chữa sẽ chính xác hơn.
