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. As For A. B.

C.

Since A

D.

Because

答案: 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。 you don't feel well,you'd better stay at home.

例2 A. C.

Because For B

B. D.

Since/If Now

答案: 例3

I don’t know A. if C. what 答案: 提示: A

he has received the package. B. D. when how many

if 表示是否,when 不能与现在完成时连用。 I will give it to you. B. D. and if

例4

Come tomorrow, A. or C. though 答案: 提示: B

and 在此处解释为“那么” ,表示递进关系。 his students likes football. B. D. as well as also

例5

The teacher A. and C. and also 答案: 提示: B

as well as 连接两个主语用靠前原则。 some one knocked at the door. B. D. a soon as while

例6

We were having lunch A. as C. when 答案: 提示: C

when 在这里解释“就在那时”
