Conjunctions

一.连词的概念1. 在句子中用来连接词与词、短语与短语或句子 与句子的词。 2. 连词在句子中不能单独作句子成分，只能起连 接作用，如：1) I study English and Chinese. 2) Does he work at school or in the hospital? 3) I get up early, but my brother gets up late. 4) I am very busy but happy.(我很忙但我很快乐)

二.连词的分类1.并列连词连接的单词、短语或句子具有对等关 系，就是具有相同的词性、相同的结构和形态。and(和), but(但是), or(或者), for(因为), so(所以) …both…and…( 和 都 ), either…or…(不是…就是…) not only…but also…(不仅 而且 )。如：1) I ate a hamburger, but I’m not full yet.2) let’s go and play football.3)I cleaned the house and washed clothes this morning. 4)Are you going to travel by train or by air?

5)Not only Jane but also her parents like cooking.

2. 从属连词：用来连接主句和从句。before( 之前), because(因为) though(尽管), after( 之后), when(当 时候) if(如果) as soon as(一 就 ) although(尽管)

如： 1)She didn’t go to school because she was ill.2)I found her bag after she has left.(她走了以后，我发现了她的书包)

3)He studied hard though he had a fever. 4)I was painting the wall when he called me.(他给我打电话时，我正在刷墙)

5)If you get tickets, please let me know.(如果您买到票，请告诉我)

根据连词在句子中表示逻辑关系的不同，也可分为以下四类：1) 表示因果关系的：because, for, so(所以), since(既然) 2) 表示平行并列、选择关系的：and (和) or(…或…) either…or…(不是…就是…) (…和…都…)

neither…nor…

(既不…也不…)

both…and…

not only…but also

(不仅…而且…)

3) 表示时间关系的：after, before, when,as soon as

4)其它常用连词：表示条件关系的：if

表示让步的：although / though

(尽管)

三.常见连词的用法1. 用“and”连接多个对象时，最后两个对象间用 “and”连接， 前面的其它对象间用逗号。

Bob entered the room, took off the coat and sat down in the sofa.2. and 通常用在肯定句中，而 or 通常用在否定句和疑问句中,。

1)He likes milk and juice.2)He doesn’t like milk or juice.(在否定句中表示并列) 3)Which do you like better, apples or pears?(在疑问句中表示选择) 3.在同一个句子中，不能同时出现 because 和 so 。 如：Because John was ill, so I took him to the doctor. 应改为：John was ill, so I took him to the doctor. 或： I took him to the doctor because John was ill

4. though / although不能和 but 和连用。 如：Although he is over sixty, but he works as hard as othe

rs. 改为：Although he is over sixty, he works as hard as others. 或：He is over sixty, but he works as hard as others. 5. “both…and…”( 和 都 / 两者 都 ) 意思相近，有时可以通用 “not only…but olso…” (不仅 而且 ) 如：Both you and he speaks French.(你和他都讲法语) Not only you but also he speaks French.(不但你而且他也讲法语)

6. neither … nor … 本身已经表示两者都否定，所以句子不再用否定式。 Neither she nor I are interested in ice cream. (她和我都不喜欢冰淇淋)

7. 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”】

① Either you or I am going to the party. (或者你或者我将去晚会)

② Neither I nor he has seen the movie.(我和他都没有看过这部电影)③ Not only you but also he speaks French.(不但你而且他也讲法语)8. and 和 or 都可以在祈使句中使用. “and + 句子”通常是比较好的结果，意思是“…那么就会” “or + 句子”则表示不愉快不理想的结果，意思是“…否则就会” 如：Study hard, and your math will be better.(努力学习，那么你的数学成绩将会很好)

Study hard, or your math will be worse.(努力学习，否则你的数学成绩将会很差)
