教学目标

掌握连词的定义：用于连接单词、短语、句子或从句的词叫连词。连词按结构可分为：简单连词,如：and,or,but,for等，关联连词，如：not only...but also,either...or...，both...and等，短语连词，如：so that，as if,even though等；按语法含义可分为并列连词、从属连词和连接副词。

掌握常用连词的用法，熟练运用。

第一课时

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。

实战演练

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。

例2 you don't feel well，you'd better stay at home．

A．Because B．Since/If

C．For D．Now

答案： B

例3 I don’t know he has received the package.

A．if B．when

C．what D．how many

答案： A

提示：if表示是否，when不能与现在完成时连用。

例4 Come tomorrow, I will give it to you.

A．or B．and

C．though D．if

答案： B

提示：and在此处解释为“那么”，表示递进关系。

例5 The teacher his students likes football.

A．and B．as well as

C．and also D．also

答案： B

提示：as well as 连接两个主语用靠前原则。

例6 We were having lunch some one knocked at the door.

A．as B． a soon as

C．when D．while

答案： C

提示：when在这里解释“就在那时”

第二课时

复习时需要注意的要点

1）You can go to Beijing either today or tomorrow

2）You must get up early or you wo n’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：

1）His brother is fond of football while he likes basketball.

2）You can watch TV, but you must finish your homework first.

（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：

1）To study English well, we need both diligence and careful.

2）That horse is not only the youngest among the five, but also runs the fastest.

（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
