初中英语语法连词讲解及练习（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bothand，either or，neithernor，not onlybut 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 didnt 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 hardand 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, whether, 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/soas 如：If it snows tomorrow，we wont 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）同步练习I.选择填空( )1.
