连词和状语从句
主讲老师:赵艳
1.并列连词and, but, so, or等的主要用法。
2.常用的从属连词的基本用法。
e.g. we study English and Chinese.
Does she work at school or in the hospital?

一、连词的定义:
用来连接词、短语或句子的词。
二、连词分类:


并列连词


从属连词——
连词:and, but, or, so, (for)
连词词组: either…or, neither…nor, not only…but also, both…and, (as well as)
that,whether, if, unless, while / when, until, because, so that, so…that, though/ although, even if, as…as 等
1.并列连词
连接具有并列关系的词、短语或句子。 常见的有:
(1)表并列关系的and, both…and, not only…but also, neither…nor,as well as(也,和)等。
(2)表选择关系的or, either…or等。
(3)表转折关系的but, however等。
(4)表因果关系的for, so等。
三、连词的用法

and (“和,并且”) 与 or (“否则”)
肯定句中用“and” 表“和”;
否定句中用“or”表“和” 。
“and”意为“这样,那么”;
“or” 意为 “否则” 。

考点二 :
考点一 :
表转折的连词but 和however:
but 后没有逗号,直接连接分句; however 后有逗号相隔,可放句末。
although/ though 和but这两个关联词不能同时用
考点三 :
because 和 so 等关联词都不能同时使用。
考点四
either A or B “或者A或者B”
neither A nor B “既不A也不B”
not only A but also B “不仅A而且B”
【连接主语 时,谓语“就近原则”】
引导词有when, as, while, before, after, since, till, until, not…until…, as soon as。
I'll ring you as soon as I reach Beijing.
我一到北京就给你打电话。

3.原因状语从句。
引导词有so that, in order that。

4.目的状语从句。

9.地点状语从句。
10.引导宾语从句的that, if , whether等。
  在时间状语从句和条件状语从句中,主句和从句之间的时态一致问题一般分为下列两种情况:
(1)主现从现:
若主句是祈使句或主句中有情态动词时,那么从句用一般现在时表示将来。
Be careful when you cross the road.
过马路时要小心。
3.主句与从句时态一致的问题
(2)主将从现: 主句用一般将来时,而从句用一般现在时。
If she ______ here tomorrow, I will go to the park with her.
如果明天她来这里,我将和她一起去公园。

(3)宾语从句和状语从句同时出现。
I don't know if(是否) he will come.
If(如果) he comes, I will tell him about the accident.
我不知道他是否会来。如果他来的话,我将告诉他这起事故。
comes 
(4)过去时态:
若主从句都是在叙述过去的事情,则主从句可以用一般过去时或过去进行时。
My mother was cooking when I got home yesterday.
昨天我到家时妈妈正在做饭。
注意一
“when” 和 “while”
when引导的状语从句的动作多为终止性动词,也为可持续动词;但while只能是可持续动词。
Mr. White was taking a shower _____ the UFO landed on the street.
A. where B. while C. when D. whether
C
While Mr. White was taking a shower,the UFO landed on the street.
注意二
not…until/ till 直到……才
…till 直到……为止

I will work till you come back.
so that:①为了; ② 所以,结果
so…that
如此……以致
