中考英语介词       连词
【考点直击】

1. 常用介词及其词组的主要用法和意义;

2. 常用动词、形容词与介词、副词的固定搭配及其意义。

3. 并列连词    and, but, or, so 等的主要用法;

4. 常用的从属连词的基本用法
【名师点睛】

1. 介词的功能
介词是一种虚词,用来表示名词或相当于名词的其它词语句中其它

词的关系,不能单独使用。介词可与名词或相当于名词的其它词构

成介词短语。介词短语可在句中作定语,状语,表语和宾语补足语。

例如:

The boy over there is John’s brother. (定语)

The girl will be back in two hours.  (状语)

Our English teacher is from Australia. (表语)

Help yourself to some fish.   (宾语补足语)

2. 常用介词的用法辨析

(1)表时间的介词

1)at, in on

表示时间点用      at。例如:at six o’clock, at noon, at midnight。
表示在某个世纪,某年,某月,某个季节以及早晨,上午,下午,

晚上时,用     in。例如:in the ninettenth century, in 2002, in 
             中国现代教育网  www.30edu.com  全国最大教师交流平台

may, in winter, in the morning, in the afternoon 等。表示具体

的某一天和某一天的上午,下午,晚上时,用                   on。例如:on 

Monday, on July 1st, on Sunday morning 等。

2) since, after

由 since 和 after 引导的词组都可表示从过去某一点开始的时段,

但 since 词组表示的时段一直延续到说话的时刻,因而往往要与现

在完成时连用。而        after 词组所表示的时段纯系过去,因而要与一
般过去时连用。例如:

I haven’t heard from him since last summer.

After five days the boy came back.

3) in, after

in 与将来时态连用时,表示“过多长时间以后”的意思,后面跟表

示一段时间的词语。After         与将来时态连用时,后面只能跟表示时间

点的词语。After     与过去时态连用时,后面才能跟表示一段时间的词
语。例如:

He will be back in two months.

He will arrive after four o’clock.

He returned after a month.

(2)表示地点的介词

1)at, in, on

at 一般指小地方;in      一般指大地方或某个范围之内;on              往往表示
“在某个物体的表面”。例如:
             中国现代教育网  www.30edu.com  全国最大教师交流平台

He arrived in Shanghai yesterday.

They arrived at a small village before dark.

There is a big hole in the wall.

The teacher put up a picture on the wall.

2) over, above, on

over, on 和 above 都可表示“在……上面”,但具体含义不同。

Over 表示位置高于某物,在某物的正上方,其反义词是                     under。 

above 也表示位置高于某物,但不一定在正上方,其反义词是

below。On   指两个物体表面接触,一个在另一的上面。例如:

There is a bridge over the river.

We flew above the clouds.

    They put some flowers on the teacher’s desk.

3) across, through

across 和 through 均可表示“从这一边到另一边”,但用法不同。

Across 的含义与    on 有关,表示动作在某一物体的表面进行。

Throgh 的含义与    in 有关,表示动作是在三维空间进行。例如:

The dog ran across the grass.

The boy swam across the river.

    They walked through the forest.

    I pushed through the crowds.

4) in front of, in the front of

in front of 表示“在某人或某物的前面”,在某个范围以外;in 
             中国现代教育网  www.30edu.com  全国最大教师交流平台

the front of 表示“在……的前部”,在某个范围以内。例如:

There are some tall trees in front of the building.

The teacher is sitting in the front of the classroom.

3. 介词的固定搭配

    介词往往同其他词类形成了固定搭配关系。记住这种固定搭配关
系,才能正确使用介词。

(1)介词与动词的搭配

listen to , laugh at, get to, look for wait for, hear from, turn on, 

turn off, worry about, think of, look after, spend…on…, 等。

(2)介词与名词的搭配

on time, in time, by bus, on foot, with pleasure, on one’s 

way to, in trouble, at breakfast, at the end of, in the end 等。

(3)介词与形容词的搭配

be late for, be afraid of, be good at, be interested in, be angry 

with, be full of, be sorry for 等。

4. 连词的功能
用来连接词,短语,从句或句子的词叫连词。连词是一种虚词,在

句中不能单独使用。连词可分为两类:并列连词和从属连词。

5. 并列连词
并列连词用来连接具有并列关系的词,短语或句子。常见的并列连

词有:

(1)表并列关系的      and, both…and, not only…but also, 
             中国现代教育网  www.30edu.com  全国最大教师交流平台

neither…nor 等。

(2)表选择关系的      or, either…or 等。

(3)表转折关系的      but, while 等。

(4)表因果关系的      for, so 等。

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:
             中国现代教育网  www.30edu.com  全国最大教师交流平台

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
             中国现代教育网  www.30edu.com  全国最大教师交流平台

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.

(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:
             中国现代教育网  www.30edu.com  全国最大教师交流平台

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
             中国现代教育网  www.30edu.com  全国最大教师交流平台

“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.
