初中英语连词讲解

一、概念

连接词与词、短语与短语、句子与句子的词叫连词。例如：

It is neither too cold nor too hot in spring.

(neither…nor连接两个词)

You can read either in the morning or in the afternoon.

(either…or连接两个短语)

Hu Lan was late yesterday because she woke up too late.

(because连接两个句子)

二、连词的种类

从连词本身的含义及其所连接的成分的性质来看，可分为两类：并列连词和从属连词。

（一）并列连词，用来连接有并列关系的词、短语或分句的连词是并列连词；并列连词连接分句构成并列句。

1、常用来连接同类性质的词与词、短语与短语的并列连词有and,

or ,neither…nor,either…or, not only…but also, both…and.

⑴ and 和，并且

My uncle lives and works in Shanghai.

He’s big and tall.

⑵ or 或（费否定句中），和（否定句中）

Are you a teacher or a student?

You can take some food or some money.

I don’t like reading or writing.

⑶neither…nor既不…也不…，要么…要么…

either…or 或者…或者…

not only…but also不仅…而且…

both…and既…又…

You can come to see me either on Sunday or on Saturday.

I don’t like its color, it is either too dark or too light.

The boy is both tall and fat.

My daughter can not only sing but also dance.

注意：both…and连接并列主语时，谓语动词用复数；neither…nor,either…or,

not only…but also连接并列主语时谓语动词和邻近主语保持一致。

2、常用来连接并列分句构成并列句的连词有and, or, but,so

⑴or否则，相当于一个否定条件句。

Hurry up, or you’ll be late.

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

⑵ and 这样的话，就会…，相当于一个肯定条件句。

Study hard, and you can get good grades.

(If you study hard, you can get good grades.)

⑶ however 然而， but 但是，可是，而,前后分句是转折关系。

Mr. Mott is very poor, but he feels happy.

⑷ so 于是，因此，并列具有因果关系的两个分句。

We wanted to learn the English songs, so we asked the teacher to teach us.

(二)从属连词：引导从句的连词叫做从属连词，分为连接代词和连接副词两种。

1、引导宾语从句的有that, when, where, who, why, what, if, whether

⑴ that 用于引导由陈述句转换过来的宾语从句，可以省去。如：

She says that she likes watching TV very much.

⑵ when,where,who, why, what等连接由特殊疑问句转换过来的宾语从句。如： Do you know when the train arrives?

Can you tell me where you come from?

⑶ if, whether连接由一般疑问句转换过来的宾语从句。如：

They are wondering if they can get the money back.

She asked the librarian whether she had to pay for the lost book.

注意：下列几种情况下不能使用if来引导的宾语从句。

①介词后的宾语从句不能使用if 引导。

Are you interested whether she will come here?

②后跟or not 时，不能使用if 引导。

I’m not sure whether or not the shop is open.

③当后跟动词不定式时，不能使用if引导。

Do you know whether to go to the Great Wall tomorrow?

2、引导状语从句的连词有when, until, after, before, as soon as, since, for, although,

if, because, so that, as if, s o…that, while等。

①引导时间状语从句的连词有：

when, while, until, after, before, as soon as(一…就…)，since(自从)，once(一旦)

when和while的区别

A：when既指时间点，也可指一段时间，while只指一段时间，因此when

引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词，

而while从句中的动词必须是延续性动词。

B：when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；

while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作

同时发生。

C:由when引导的时间状语从句，主句用过去进行时，从句应用一般过去

时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多

用while引导。

When the teacher came in, we were talking.

While we were talking, the teacher came in.

They were singing while we were dancing

②引导条件状语从句的连词有：

If, unless, as long as(只要)， as far as(就…而言)

③引导原因状语从句的连词有：

because, for, now that(既然,因为，由于)，since(既然)

④引导结果状语从句的连词有：

so…that,such…that

⑤引导比较状语从句的连词有：

than, as … as

⑥引导目的状语从句的连词有：

so that (以便)， in order that(为了)， in case(以防，以免)

⑦引导让步状语从句的连词有：

though, although, even if/ even though(即使)，no matter+疑问词（无论，不管）

⑧引导地点状语从句的连词有：

wherever

⑨引导方式状语从句的连词有：

as if/ as though(好像)，as
