初中英语分类练习
——连词部分
连词在句中的作用是把词与词、短语与短语、句子与句子连接起来。它不能在句中单独作句子成分。
知识点概述
并列连词和从属连词的用法
连词是连结单词、短语、从句或句子的虚词, 在句子中不单独作句子成份。
连词按其性质可分为:
1.并列连词 如:and, or, but, for, 等, 连接并列的词与词,短语与短语,句子与句子。
如:Rice and potatoes are common foods. (词与词)
Today we can travel by plane. (短语与短语)
Many trees lose their leaves in winter, but evergreen trees do not. ( 句子与句子)
关联连词是一类成对使用的连词
如:both……and……, not……but…….
not only……but also…… not only…but… as well
either……or…… neither……nor……
关联连词必须后接同样的语法结构。
如:Either the windows were opened or the door was opened.
2.从属连词 如:that, whether, when, because, though 等, 用以引导名词性从句和状语从句。
3.从属连词引导的从句不可以被断成一个句子。 如果断开,就错了。
如:When the alarm clock rang. (不完整)
4. though (although)引导让步状语从句,because 引导原因状语从句, 所以though(although)不能和并列连词but ,because 不能和并列连词 so一起使用。 只能单独使用。
二、复习时需要注意的要点
(1)表示选择关系的连词,连接的双方只取其一。常用连词有or, either...or, otherwise
例如:
1)You can go to Beijing either today or tomorrow
2)You must get up early or you won't catch the early bus.
(2)表示转折关系,连接的双方构成对比,意义上有转折。常用连词有but, however, while, only
例如:
(3)表示联合关系,联合的双方是对等的,意义上趋向一致。常用连词有:and, both...and, neither...nor, not only...but also, as well as, together with
例如:
(4)表示因果关系,连接的双方,互为因果,或者前因后果,或者前果后因。常用的连词有:for, so, therefore
例如:

一、例题选讲
例1 | he did not know much English,he got out his dictionary and looked up the word. | ||||||||||
A. | As | B. | For | ||||||||
C. | Since | D. | Because | ||||||||
答案: | A | ||||||||||
提示: | for,because和as虽皆可作连词用,表示"因为",但用法有些区别。for引导的分句总是置于另一分句之后,常常对前一分句加以解释,两个分句之间,总是用逗号分开。because引导的原因状语从句时,往往以why问句,语气比较重,传递的往往是对方未了解的新信息。as引导的原因状语从句时,往往是对方也知道的信息。本句是他拿出词典查,显然,"他知道的英语单词不多",这是明摆着的事,所以用as最恰当。 | ||||||||||
