B. REDUCTION OF RELATIVE CLAUSES
1) Dùng phân từ:

Dùng cho các mệnh đề mang nghĩa chủ động
The man who is standing there is my brother.
The man standing there is my brother
b) Dùng cụm P.P: (V3/ V-ed)
Dùng cho các mệnh đề mang nghĩa bị động .
I like books which were written by Nguyen Du.

2) Dùng cụm to inf: (... Noun/ Pronoun + to infinitive / to be + P.P... )
-Dùng khi danh từ đứng trước có các từ sau đây :
ONLY, LAST, FIRST, SECOND...
Ex: This is the only student who can do the problem. (động từ mang nghĩa chủ động)
This is the only student to do the problem.
-Động từ là HAVE

-Câu bắt đầu bằng: HERE (BE), THERE (BE)

Trong phần to inf này cần nhớ 2 điều sau:
- Nếu chủ từ 2 mệnh đề khác nhau thì thêm cụm for sb trước to inf.
Ex: We have some picture books that children can read.
We have some picture books for children to read.
Tuy nhiên nếu chủ từ đó là đại từ có nghĩa chung chung như: we, you, everyone.... thì có thể không cần ghi ra.
Ex: Studying abroad is the wonderful thing that we must think about.
Studying abroad is the wonderful (for us ) to think about.
- Nếu trước relative pronoun có giới từ thì phải đem xuống cuối câu.
Ex: We have a peg on which we can hang our coat.

3) Dùng cụm danh từ (đồng cách danh từ )
Dùng khi mệnh đề quan hệ có dạng:

Cách làm:
-bỏ who ,which và be
Ex: Football, which is a popular sport, is very good for health.
Football, which is a popular sport, is very good for health.
Football, a popular sport, is very good for health.
Ex: Do you like the book which is on the table?

PHƯƠNG PHÁP LÀM BÀI LOẠI RÚT GỌN:
Bước 1 : - Tìm xem mệnh đề tính từ nằm chổ nào
Bước này dễ vì mệnh đề tính từ thường bắt đầu bằng WHO,WHICH,THAT...
Bước 2 :
Bước này chủ yếu là rút gọn mệnh đề quan hệ thành cụm từ
1. Nhìn xem mệnh đề có công thức S + BE + CỤM DANH TỪ không ? Nếu có áp dụng công thức 3 .
2. Nếu không có công thức đó thì xem tiếp trứoc who which... có các dấu hiệu first ,only...v..v không ,nếu có thì áp dụng công thức 2 (to inf. ) lưu ý thêm xem 2 chủ từ có khác nhau không ( để dùng for sb )
3. Nếu không có 2 trừong hợp trên mới xét xem câu đó chủ động hay bị động mà dùng V-NG hay P.P..
