TỔNG HỢP KIẾN THỨC MỆNH ĐỀ QUAN HỆ TRONG TIẾNG ANH
1. Lý thuyết
1.1. Định nghĩa
- Mệnh đề (Clause) là một phần của câu, nó có thể bao gồm nhiều từ hay có cấu trúc của cả một câu. Mệnh đề quan hệ dùng để giải thích rõ hơn về danh từ đứng trước nó.
- Mệnh đề quan hệ (mệnh đề tính từ) bắt đầu bằng các đại từ quan hệ: who, whom, which, that, whose hay những trạng từ quan hệ: why, where, when. Mệnh đề quan hệ dùng để bổ nghĩa cho danh từ đứng trước nó.
Xét ví dụ sau:
- The woman who is wearing the T-shirt is my girlfriend.
Trong câu này phần in đậm được gọi là một mệnh đề quan hệ, đứng sau “the woman” và dùng để xác định danh từ đó. Nếu bỏ mệnh đề này ra chúng ta vẫn có một câu hoàn chỉnh:
1.2. Các dạng mệnh đề quan hệ trong tiếng Anh
Có hai loại mệnh đề quan hệ: mệnh đề quan hệ xác định và mệnh đề quan hệ không xác định.
a. Mệnh đề quan hệ xác định (Defining relative clauses): là mệnh đề được dùng để xác định danh từ đứng trước nó. Mệnh đề xác định là mệnh đề cần thiết cho ý nghĩa của câu, không có nó câu sẽ không đủ nghĩa. Nó được sử dụng khi danh từ là danh từ không xác định và không dùng dấu phẩy ngăn cách nó với mệnh đề chính.
b. Mệnh đề quan hệ không xác định (Non-defining relative clauses): là mệnh đề cung cấp thêm thông tin về một người, một vật hoặc một sự việc đã được xác định. Mệnh đề không xác định là mệnh đề không nhất thiết phải có trong câu, không có nó câu vẫn đủ nghĩa. Nó được sử dụng khi danh từ là danh từ xác định và được ngăn cách với mệnh đề chính bằng một hoặc hai dấu phẩy (,) hay dấu gạch ngang (-)
Ex: Dalat, which I visited last summer, is very beautiful. (Non-defining relative clause)
Note: để biết khi nào dùng mệnh đề quan hệ không xác định, ta lưu ý các điểm sau:
- Khi danh từ mà nó bổ nghĩa là một danh từ riêng
- Khi danh từ mà nó bổ nghĩa là một tính từ sở hữu (my, his, her, their)
- Khi danh từ mà nó bổ nghĩa la một danh từ đi với this , that, these, those
1.3. Phân loại các đại từ quan hệ trong tiếng Anh
a. WHO:
- làm chủ từ trong mệnh đề quan hệ
- thay thế cho danh từ chỉ người.....
- Cấu trúc: N (person) + WHO + V + O
- Ví dụ: I told you about the woman who lives next door.
b. WHOM:
- làm túc từ cho động từ trong mệnh đề quan hệ
- thay thế cho danh từ chỉ người
- Cấu trúc: .....N (person) + WHOM + S + V
- Ví dụ: I was invited by the professor whom I met at the conference.
c. WHICH:
- làm chủ từ hoặc túc từ trong mệnh đề quan hệ
- thay thế cho danh từ chỉ vật
- Cấu trúc:
....N (thing) + WHICH + V + O
....N (thing) + WHICH + S + V
- Ví dụ:
+ Do you see the cat which is lying on the roof?
+ He couldn’t read which surprised me
d. THAT:
- có thể thay thế cho vị trí của who, whom, which trong mệnh đề quan hệ quan hệ xác định
* Các trường hợp thường dùng "that":
- khi đi sau các hình thức so sánh nhất
- khi đi sau các từ: only, the first, the last
- khi danh từ đi trước bao gôm cả người và vật
- khi đi sau các đại từ bất định, đại từ phủ định, đại từ chỉ số lượng: no one, nobody, nothing, anyone, anything, anybody, someone, something, somebody, all, some, any, little, none.
Ví dụ:
+ He was the most interesting person that I have ever met.
+ It was the first time that I heard of it.
+ These books are all that my sister left me. 0983672757
+ She talked about the people and places that she had visited.
* Các trường hợp không dùng that:
- trong mệnh đề quan hệ không xác định
- sau giới từ
e. WHOSE:
- dùng để chỉ sở hữu cho danh từ chỉ người hoặc vật, thường thay cho các từ: her, his, their, hoặc hình thức 's
- .Cấu trúc....N (person, thing) + WHOSE + N + V ....
- Ví dụ: Do you know the boy whose mother is a nurse?
1.4. Phân loại các trạng từ quan hệ trong tiếng Anh
a. WHY: mở đầu cho mệnh đề quan hệ chỉ lý do, thường thay cho cụm for the reason, for that reason
- Cấu trúc: ......N (reason) + WHY + S + V ...
Ví dụ: I don‟t know the reason. You didn‟t go to school for that reason.
→ I don‟t know the reason why you didn‟t go to school.
b. WHERE: thay thế từ chỉ nơi chốn, thường thay cho there
- Cấu trúc:
....N (place) + WHERE + S + V ....
(WHERE = ON / IN / AT + WHICH)
Ví dụ: a/ The hotel wasn‟t very clean. We stayed t that hotel.
→ The hotel where we stayed wasn‟t very clean.
→ The hotel at which we stayed wasn‟t very clean.
c. WHEN: thay thế từ chỉ thời gian, thường thay cho từ then
Cấu trúc: ....N (time) + WHEN + S + V ...
(WHEN = ON / IN / AT + WHICH)
Ví dụ: Do you still remember the day? We first met on that day.
→ Do you still remember the day when we first met?
→ Do you still remember the day on which we first met?
I don't know the time. She will come back then.
→ I don't know the time when she will come back.
1.5. Một số lưu ý về mệnh đề quan hệ
a. Nếu trong mệnh đề quan hệ có giới từ thì giới từ có thể đặt trước hoặc sau mệnh đề quan hệ (chỉ áp dụng với whom và which.)
Ví dụ: Mr. Brown is a nice teacher. We studied with him last year.
→ Mr. Brown, with whom we studied last year, is a nice teacher.
→ Mr. Brown, whom we studied with last year, is a nice teacher.
b. Có thể dùng which thay cho cả mệnh đề đứng trước.
Ví dụ: She can't come to my birthday party. That makes me sad.
→ She can't come to my birthday party, which makes me sad.
c. Ở vị trí túc từ, whom có thể được thay bằng who.
Ví dụ: I'd like to talk to the man whom / who I met at your birthday party.
d. Trong mệnh đề quan hệ xác định , chúng ta có thể bỏ các đại từ quan hệ làm túc từ: whom, which.
Ví dụ: The girl you met yesterday is my close friend. The book you lent me was very interesting.
e. Các cụm từ chỉ số lượng some of, both of, all of, neither of, many of, none of ... có thể được dùng trước whom, which và whose.
Ví dụ: I have two sisters, both of whom are students. She tried on three dresses, none of which fitted her.
