Phát hiện lỗi sai

nh lỗi sai trong câu sau
We (A) only get (B) home (C) from France (D) yesterday.
Do có trạng từ yesterday (hôm qua) nên động từ phải chia ở thì quá khứ - lỗi sai cần tìm là B.
Sai đại từ quan hệ
Các đại từ quan hệ who, whose, whom, which, that... đều có cách sử dụng khác nhau. Ví dụ who thay thế cho danh từ chỉ người đóng vai trò là chủ ngữ, which thay thế cho danh từ chỉ vật...
Ví dụ: Xác định lỗi sai trong câu sau
He gave (A) orders to the manager (B) whose (C) passed them (D) on to the foreman.
Whose là đại từ quan hệ đóng vai trò là tính từ sở hữu. Trong trường hợp này ta dùng một đại từ bổ nghĩa cho danh từ manager. Do đó, ta dùng who – lỗi sai cần tìm là C
Sai về bổ ngữ
Các em phải chú ý khi nào thì dùng to infinitive, bare infinitive hoặc V-ing.
Ví dụ: Xác định lỗi sai trong câu sau 
I want to travel (A) because (B) I enjoy to meet (C) people and seeing new places (D).
Ta có cấu trúc: enjoy + V-ing nên lỗi sai cần tìm là C.
Sai về câu điều kiện
Có 3 loại câu điều kiện với 3 cấu trúc và cách dùng khác nhau. Chỉ cần ghi nhớ và áp dụng đúng thì việc xác định lỗi sai sẽ không hề khó khăn.
Ví dụ: Xác định lỗi sai trong câu sau
What would (A) you do (B) if you will win (C) a million (D) pounds?
Đây là câu điều kiện không có thực ở hiện tại nên động từ ở mệnh đề if chia ở quá khứ. (To be được chia là were cho tất cả các ngôi).
Sai về giới từ
Giới từ thường đi thành cụm cố định như to be fond of, to be fed up with, to depend on, at least.... Các em cần phải học thuộc lòng những cụm từ đó.
Ví dụ: Xác định lỗi sai trong câu sau
We're relying (A) with (B) you to find (C) a solution (D) to this problem.
To rely on sb: tin cậy, trông đợi vào ai. Do đó, B là đáp án cần tìm.
Sai hình thức so sánh
Có 3 hình thức so sánh là so sánh bằng, so sánh hơn và so sánh nhất. Các em phải nắm vững cấu trúc của từng loại vì người ra đề thường cho sai hình thức so sánh của tính/ trạng từ hoặc cố tình làm lẫn giữa 3 loại so sánh với nhau.
Ví dụ: Xác định lỗi sai trong câu sau
The North (A) of England (B) is as industrial (C) than the South (D).
Đây là câu so sánh hơn vì có than – as industrial phải được chuyển thành more industrial.
So...that... và such...that...
Ta có 2 cấu trúc câu sau:
So + adj/ adv + that + clause
Such + (a/ an) + adj + n + that + clause
Quan sát câu đã cho xem có mạo từ a/ an hay danh từ hay không để dùng so hoặc such.
Ví dụ: Xác định lỗi sai trong câu sau
It seems (A) like so (B) a long way to drive (C) for just (D) one day.
Có mạo từ a nên câu phải dùng cấu trúc such...that... B là đáp án cần tìm. 
Many và much
Các em học sinh cũng hay nhầm lẫn giữa many và much. Many dùng trước danh từ đếm được số nhiều còn much dùng trước danh từ không đếm được.
Ví dụ: Xác định lỗi sai trong câu sau
I don't want to invite (A) too much (B) people because (C) it's quite (D) a small flat.
People là danh từ đếm được nên phải dùng many thay cho much.
