定語從句中的動詞的時態要根據具體情況選擇，不一定都是-ed形式。

如 I like the girl who walks to school everyday.

I like the girl who danced yesterday.

I like the girl who has finished her college study.

定語從句由關係代詞who、whom、whose、which、what、as和關係副詞where、when、why等引導，但須記住：

1.what不能引導定語從句.

2.關係詞的分析須考慮它在定語從句中的成分。

定語從句後面的動詞形式有很多

比如加ing、ed、不定式，而加了ed來修飾的，一般情況下要麼是被動語態

要麼是過去式或者現在完成時

比如：

I saw the boy who helped me yesterday.

這是一個典型的過去式 所以加ed

1. The man who is sitting on the platform is a professor from Wuhan University.

2. The letter that was mailed last night will reach him tomorrow.

3. You are welcome to a party to be given in our class at 7:45

別的還有很多的時態需要具體分析

　　1. 被修飾名詞+doing短語：  正在做….的人/正在發生的事。

　　2. 被修飾名詞+ done短語：  被…..的人/事

　　3. 被修飾名詞+being done短語：正在被…..的人/事

　　4. 被修飾名詞+ to be done短語：將要被…..的人/事

定語從句中的動詞的時態要根據具體情況選擇，不一定都是-ed形式。

如 I like the girl who walks to school everyday.

I like the girl who danced yesterday.

I like the girl who has finished her college study.

定語從句的用法

定語從句由關係代詞who、whom、whose、which、what、as和關係副詞where、when、why等引導，但須記住：

1.what不能引導定語從句.

2.關係詞的分析須考慮它在定語從句中的成分。

一.指人的關係代詞有who、whose、whom、that. 試分析：

The old man who/whom /that we visited yesterday is a famous artist.

Miss Wang is taking care of the child whose parents have gone to Beijing .

The man with whom my father shook hands just now is our headmaster. （=The man who/whom that my father shook hands with just now is our headmaster.）注：

A． 指人時有時只用who不宜用that。

1．先行詞為one、ones或anyone

（1）The comrade I want to learn from is the one who studies hard and works hard.

（2）Anyone who breaks the law should be punished.

2．先行詞為these時

These who are going to Beijing are the best students of our school.

3．在there be 開頭的句子中

There is a student who wants to see you.

4．一個句子中帶有兩個定語從句，其中一個定語從句的關係代詞是that，另一個宜用who，以免重複。

The student that won the first prize is the monitor who works hards.

5．在非限制性定語從句中

A。I met a friend of mine in the street, who had just come from Japan.

B．主句以who開頭的句子中,只用that,不用who。

that和which引導定語從句的區別

that \which在代物時常常可以通用,但有時只宜於用which ,不用that

(1) 關係代詞前有介詞時.

This

is the hotel in which you will stay.

(2)

如有兩個定語從句,其中一句的關係代詞是that,另一句宜於用which.

Let me show you the novel that I

borrowed from the liberary which was newly open (新開放) to us.

注意2that

\which在代物時常常可以通用,但有時只宜於用that ,不用which.

(1) 先行詞是形容詞最高階或者它的前面有形容詞最高階時

This is the best that has been used against air pollution(反對空氣汙染) in

cities.

English is the most difficult subject that you will learn during

these years.

(2) 先行詞是序數詞,或它的前面有一個序數詞時

He is the last person that

I want to see.

(3) 主句中已有疑問詞時

Which is the bike that you lost?

(4) 先行詞既有人又有物時

The bike and its rider that had run over (撞倒了)an

old man were taken to the police station.

(5)

先行詞是all,much,little,something,everything,anything,nothing,none,the one等代詞時

You should hand in all that you have.

We haven’t got much that

we can offer you.

I mean the one that you talked about just now.

(6) 先行詞前面有only,any,few,little,no,all,one of,the same,the very等詞修飾時

The only thing that we can do is to give you some money.

Li Ming

is the only one that got full marks (滿分)in our class.

Li Ming is one of

the students that want to be teachers in our class.

(7)

有兩個定語從句,其中一個關係代詞已用which,另外一個宜用that

Edison built up a factory(辦了一個工廠)

which produced things that had never been seen before.

定語從句的關係副詞

Where的用法:若先行詞指地點且其在定語從句中充當地點狀語.

This is the house+I was born in the

house. (=I was born there)

介詞短語 副詞

=This is the house where I

was born.這就是我在那兒出生的房子.

先行詞 關係副詞

in which I was born.

介詞+關係代詞

which I was born in.

關係代詞

這裡作介賓的which和that可以省略

通俗的講就是將這兩個形容詞換成定語從句的時候,

被-ing修飾的先行詞做從句的主語,被-ed修飾的先行詞做從句的賓語,是被動態的.

而且一般動詞的-ing做形容詞,這個動詞一般是不及物動詞；-ed,一般是及物動詞
例如：

1. The man who is sitting on the platform is a professor from Wuhan University.

2. The letter that was mailed last night will reach him tomorrow.

3. You are welcome to a party to be given in our class at 7:45.

說明：以上的定語從句部分可以用更加簡單的非謂語形式表達出來：

1. The man sitting on the platform is a professor from Wuhan University.

2. The letter mailed last night will reach him tomorrow.

3. You are welcome to a party to be given in our class at 7:45.

修飾一個名詞除了後面用定語從句以外，還可以用非謂語動詞形式：doing短語，done短語，being done短語，to be done短語修飾。其結構和意思如下：

　　1. 被修飾名詞+doing短語： 正在做….的人/正在發生的事。

　　2. 被修飾名詞+ done短語： 被…..的人/事

　　3. 被修飾名詞+being done短語：正在被…..的人/事

　　4. 被修飾名詞+ to be done短語：將要被…..的人/事
