  七年級英語語法知識

定語從句

1. 定語從句的概念

在複合句中,修飾某一名詞或代詞的`從句叫定語從句。被修飾的名詞或代詞叫先行詞,引導定語從句的詞叫關係詞,定語從句一般放在先行詞的後面。

2. 定語從句的關係詞

引導定語從句的關係詞有關係代詞和關係副詞,常見的關係代詞包括that, which, who(賓格whom,所有格whose)等,關係副詞包括where, when, why等。關係代詞和關係副詞放在先行詞及定語從句之間起連線作用,同時又作定語從句的重要成分。

3. 定語從句的分類

根據定語從句與先行詞的關係,定語從句可分為限制性定語從句及非限制性定語從句。限制性定語從句緊跟先行詞,主句與從句不用逗號分開,從句不可省去。非限制性定語從句與主句之間有逗號分開,起補充說明作用,如省去,意思仍完整。

4. 關係代詞的用法

(1)that 既可以用於指人,也可以用於指物。在從句中作主語、賓語或表語。作主語時不可省略,作賓語可省略。例如:

Mary likes music that is quiet and gentle.

瑪麗喜歡輕柔的音樂。(that作主語)

The coat (that) I put on the desk is blue.

我放在桌子上的那件外套是藍色的。(that作賓語)

(2)which用於指物,在句中作主語、賓語或表語。作主語不可省略,作賓語可省略。例如:

The building which stands near the train station is asupermarket.

位於火車站附近的那座大樓是一家超市。(作主語)

The film (which) we saw last night was wonderful.

我們昨天晚上看的那部電影很好看。(作賓語)

(3)who, whom用於指人,who 用作主語,whom用作賓語。在口語中,有時可用who代替whom。who和whom作賓語時也可省略。例如:

The girl who often helps me with my English is fromEngland.

經常在英語方面幫助我的那個女孩是英國人。(作主語)

Who is the teacher (whom) Li Ming is talking to?

正在與李明談話的老師是誰?(作賓語)

4. 關係副詞的用法

(1)when指時間,其先行詞表示時間,when在定語從句中作時間狀語。例如:

This was the time when he arrived.

這是他到達的時間。

(2)where指地點,其先行詞表示地點,where在定語從句中作地點狀語。例如:

This is place where he works.

這是他工作的地點。

(3)why 指原因,其先行詞是原因,why在定語從句中做原因狀語。例如:

Nobody knows the reason why he is often late for school.

沒人知道他為什麼上學總遲到。

狀語從句

1. 時間狀語從句

(1)時間狀語從句常用when, as, while, before, after, since, till, until, as soon as等連詞來引導。例如:

It was raining hard when got to school yesterday.

While he was doing his homework, the telephone rang.

As he walked along the lake, he sang happily.

He had learned a little Chinese before he came to China.

After he finished middle school, he went to work in a factory.

(2)在時間狀語從句裡,通常不用將來時態,用現在時態表示將來的動作或狀態。例如:

I’ll ring you up as soon as I get to New York.

I will tell him everything when he comes back.

He won’t believe it until he sees it with his own eyes.

(3)在帶有till或until引導的時間狀語從句的主從複合句裡,如果主句用肯定式,其含義是“一直到……時”,謂語動詞只能用延續性動詞。如果主句用否定式,其含義是“直到……才……”, “在……以前不……”, 謂語動詞可用瞬間動詞。例如:

The young man read till the light went out.

Let’s wait until the rain stops.

We won’t start until Bob comes.

Don’t get off until the bus stops.

2. 條件狀語從句

(1)條件狀語從句通常由if, unless引導。例如:

What shall we do if it snows tomorrow?

Don’t leave the building unless I tell you to.

(2)在條件狀語從句裡,謂語動詞通常用現在時態表示將來的動作或狀態。例如:

I’ll help you with your English if am free tomorrow.

He won’t be late unless he is ill.

(3)“祈使句 + and (or)+ 陳述句” 在意思上相當於一個帶有條件狀語從句的複合句。例如:

Hurry up, or you’ll be late.

=If you don’t hurry up, you’ll be late.

Study hard and you will pass the exam.

=If you study hard, you will pass the exam.

3. 原因狀語從句

(1)原因狀語從句通常由because, since, as引導。例如:

He didn’t come to school because he was ill.

As it is raining, we shall not go the zoo.

Since you can’t answer the question, I’ll ask someone else.

(2)because表示直接原因,語氣最強。Because引導的原因狀語從句多放在主句之後。回答由why提出的問題,只能用because。As和since語氣較弱,一般用來表示明顯的原因。由as和since引導的原因狀語從居多放在句首。例如:

------Why aren’t going there?

------Because I don’t want to.

As he has no car, he can’t get there easily.

Since we have no money, we can’t buy it.
