中考指导:初中英语语法之介词(4篇)

1.中考指导:初中英语语法之介词 篇一

6.从属连词

从属连词用来引导从句。常见的从属连词有:

(1)引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。(2)引导条件状语从句的if, unless等。

(3)引导原因状语从句的because, as, since等。

(4)引导目的状语从句的so that, in order that等。

(5)引导让步状语从句的though, although, even if等。

(6)引导结果状语从句的so that, so…that, such…that等。

(7)引导比较状语从句的than, as…as等。

(8)引导名词从句的that, if , whether等。

7.常用连词的用法辨析

(1)while, when, as

这三个连词都可引导时间状语从句,但用法有所不同。

1)当某事正在进行的时候,又发生了另一件事。While, when, as 都可用来引导表示“背景”的时间状语从句。例如:

As/When/While I was walking down the street I noticed a police car.

2)当两个长动作同时进行的时候,最常用的是while。例如:

While mother was cooking lunch, I was doing my homework.

3)当两个动作都表示发展变化的情况时,最常用的是as。例如:

As children get older, they become more and more interested in things around them.

4)当两个短动作同时发生时,或表示“一边…一边…”时,最常用as。例如:

Just as he caught the fly, he gave a loud cry.

She looked behind from time to time as she went

5)当从句的动作先于主句的动作时,通常用when。例如:

When he finished his work, he took a short rest.

6)当从句是瞬间动作,主句是延续性动作时,通常用when。例如:

When John arrived I was cooking lunch.

(2)as, because, since , for

这四个词都可表原因,但用法有区别。

1)如果原因构成句子的最主要部分,一般用because。因此,because引导的从句往往放在句末。例如:

I stayed at home because it rained.

---Why aren’t you going?

---Because I don’t want to.

2)如果原因已被人们所知,或不如句子的其它部分重要,就用as或since。Since比as稍微正式一点。As和since 引导的从句一般放在句子的开头。例如:

As he wasn’t ready, we left without him.

Since I have no money, I can’t buy any food.

3)for用来补充说明一种理由,因此,for引导的从句几乎可以放在括号里。For引导的句子不放在句子的开头。例如:

I decided to stop and have lunch----for I was feeling quite hungry.www.zhongkao5.com//

(3)if, whether

if和whether都可作“是否”讲,在引导宾与从句是一般可互换。例如:

I wonder whether (if) you still study in that school.

I don’t know whether (if) he likes that film.

在下列情况下,只能用whether,不能用if:

1)引导主语从句时。例如:

Whether he will come to the party is unknown.

2)引导表语从句时。例如:

The question is whether I can pass the exam.

3)在不定式前。例如:

I haven’t made up my mind whether to go there or not.

(4)so…that, such…that

1)so…that中的so是个副词,其后只能跟形容词或副词,而such…that中的such是个形容词,后接名词或名词短语。例如:

I’m so tired that I can’t walk any farther.

It was such a warm day that he went swimming.

2)如果在名词之前有many, much, little, few时,用so,不用such。例如:

He has so little education that he is unable to get a job.

I have had so many falls that I am black and blue all over.

(5)either…or…, neither…nor, not only…but also…

这三个连词词组都可连接两个并列成分。当它们连接两个并列主语时,

谓语动词要随相邻的主语变化。例如:

Either you or he is wrong.

Neither he nor his children like fish.

Not only the teacher but also the students want to buy the book.

(6)although, but

这两个连词不能用在同一个句子中。例如:我们不能说“Although he is

over sixty, but he works as hard as others.”这个句子应改为:Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as others.

(7)because, so

这两个连词同样不能用在同一个句子中。例如:我们不能说“Because John

was ill, so I took him to the doctor.” 这个句子应改为Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor.
