CÓ 2 LOẠI MỆNH ĐỀ LIÊN HỆ:
RESTRICTIVE & NON-RESTRICTIVE RELATIVE CLAUSES
I. Restrictive Relative Clauses:
- Dùng để bổ nghĩa cho danh từ đứng trước chưa được xác định rõ, nếu bỏ đi mệnh đề chính sẽ không rõ nghĩa.
 Ex: - I saw the girl. She helped us last week.
 à I saw the girl who/that helped us last week.
* LƯU Ý: Ta có thể bỏ đại từ quan hệ: WHO, WHOM, WHICH, THAT khi chúng làm tân ngữ trong MĐQH xác định.
II. Non-restritive Relative Clauses:
- Dùng để bổ nghĩa cho danh từ đứng trước đã được xác định rõ (nó chỉ là phần giải thích thêm), nếu bỏ đi mệnh đề chính vẫn rõ nghĩa. 
- Mệnh đề này ngăn cách với mệnh đề chính bằng dấu phẩy.
- Ta dùng mệnh đề quan hệ không xác định khi:
+ Trước đại từ quan hệ có: this/that/these/those/my/her/his/
+ Từ trước đại từ quan hệ là tên riêng, danh từ riêng, vật duy nhất, cụm trạng ngữ chỉ nơi chốn
 Ex: - My father is a doctor. He is fifty years old.
 à My father, who is fifty years old, is a doctor.
 - Mr. Brown is a very nice teacher. We studied English with him.
 à Mr Brown, who we studied English with, is a very nice teacher.

 à The sun, which was hot at midday, made the traveller thirsty

B. REDUCTION OF RELATIVE CLAUSES
1) Dùng phân từ:
a) Dùng cụm V-ing :
 	Dùng cho các mệnh đề mang nghĩa chủ động 
Ex:	a. The man who is standing there is my brother.
 	b. The man standing there is my brother
b) Dùng cụm P.P: (V3/ V-ed)
 	Dùng cho các mệnh đề mang nghĩa bị động .
 	a. I like books which were written by Nguyen Du.
 	b. I like books 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 
Ex: I have something that I must do now. (động từ mang nghĩa chủ động)
 I have something to do now.
-Câu bắt đầu bằng: HERE (BE), THERE (BE)
Ex: There are six letters which have to be written today. (động từ mang nghĩa bị động)
 There are six letters to be written today.
GHI NHỚ :
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.
 We have a peg to hang our coat on.
3) Dùng cụm danh từ (đồng cách danh từ )
Dùng khi mệnh đề quan hệ có dạng:
 	S + BE + DANH TỪ /CỤM DANH TỪ/CỤM GIỚI TỪ
Cách làm:
-bỏ who ,which và be 
Ex: 	a. Football, which is a popular sport, is very good for health.
 	à Football, which is a popular sport, is very good for health.
 	à Football, a popular sport, is very good for health.
Ex: 	b. Do you like the book which is on the table?
 	àDo you like the book 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..
EXERCISE 2: Use reduced relative clauses in place of the relative clauses
