中考英语语法连词语法讲解及练习

（一）连词概述

连词是连接单词、短语或句子的一种虚词。在句中不单独作句子成分。历年中考中常考并列连词and，but，neither… nor；从属连词now that，though，when。所以了解状语从句和宾语从句的真正意义有助于正确使用从属连词。

（二）基础知识梳理

1．并列连词用来连接彼此并列的词、短语或句子。并列连词有and，or，but，so，for，nor等。

2．关联连词有both…and，either… or，neither…nor，no t only…but also，as well as，as much as等。

3．连接性副词有however，therefore，besides，yet，anyway，still，all the same等。

4．并列连词和连接性副词存在以下的区别：

1)连接两个独立的分句时，并列连词的位置只能放在它所引导的分句的句首，前面通常有逗号。如：

I must work hard, for I still have a long way to go.

They all went, but I didn't go.

2)连接性副词的位置比较灵活，句中、句首、句末都可以。但是放在句首较为普遍。如：

Mother was ill, therefore, she stayed at home yesterday.

= Mother was ill, she therefore, stayed at home yesterday.

= Mother was ill, she stayed at home yesterday, therefore.

3)两个并列连词不可以连用。如：

He tried hard．and but he failed to get the job.此句中的but应改为yet。因为and和but都是连词。

5．从属连词是用来引导从句，如宾语从句、状语从句、定语从句等。从属连词有that，if, unless, w hether, who, whose, what, which, where, than, when, while, as, since, though, although, because, before, after, until, as soon as, now that, so...that, so that, as... as,(not) as/so…as 如：

If it snows tomorrow，we won't go on a picnic.（If引导条件状语从句）

Could you tell me whose PC it is? （whose引导宾语从句）

The man who is talking to my class teacher is my father.（who引导定语从句）
