连词的定义:连词是连接字、短语、从句与句子的词,是虚词,因此它不能独立担任句子成分。

连词主要分为两大类:并列连词和从属连词。

并列连词用来连接并列关系的词、词组或分句。

它包括:and,or,but,so,for,both…and,either…or,neither…nor,not only…but also。

从属连词用来引导从句,它包括:that,when,till,until,after,before,since,because,if,whether,though,although,so…that,so that,in order that,as soon as并列连词用来连接具有并列关系的词,短语或句子。

常见的并列连词有:(1)表并列关系的and, both…and, not only…but also, neither…nor等。

(2)表选择关系的or, either…or等。

(3)表转折关系的but, while等。

(4)表因果关系的for, so等。

1并列连词1 and:和,并且I like basketball,football and table-tennis.我喜欢篮球、足球和乒乓球。

1.基本用法and表示“和”、“而且”的意思,用来连接对等关系的字和字,片语与片语,句子与句子。

He got up and put on his hat.他站起来,戴上了帽子。

I went to the Summer Palace and he went to Bei Hai Park.我去颐和园,他去北海公园。

注意单词或词组如果是三个以上连接,一般在最后的单词或词组前加and。

另外“and”在译成中文时不一定要翻译出“和”来。

2.特别用法:and在祈使句中的作用句型:祈使句,and…=If you…,you'll…Use your head,and you'll find a way.动动脑筋,你就会想出办法来。

=If you use your head,you'll find a way.如果你动动脑子,你就会想出办法。

Hurry up,and you'll catch the bus.快点,你就会赶上公共汽车。

=If you hurry up,you'll catch the bus.如果你快点,你就会赶上公共汽车。

2 or:或,或者,否则Is Li Ming from Beijing or from Shanghai.李明是北京人还是上海人呢?1.基本用法or表示“~或”的意思,使用于两者之中选择一个的时候。

Would you like coffee or tea?你喜欢咖啡还是茶?Tom or I am right.我或者汤姆是对的。

Li Ming or his classmates are cleaning the room.李明或者是他的同班同学在打扫房间。

注意“A or B”作主语时,谓语动词随or后面的词(B)而定,因此例子中的谓语动词服从I,用am。

2.特别用法句型:祈使句,or…=If you don't…,you'll…同and一样,or在祈使句中的用法,译成“请…,否则…”,有转折的意思。

Hurry up,or you'll miss the bus.快点吧,否则你就会误了公共汽车。

=If you don't hurry up,you'll miss the bus.如果你不快点,你就会误了这班车。

Study hard,or you'll fail in the exam.好好学吧,否则你考试就会不及格。

=If you don't study hard,you'll fail in the exam.如果你不努力学习,你考试就会不及格。

注意or疑问句的读法or前面的部分用升调,后面的部分用降调。

3 but:但是,可是,而He is old,but he looks very young.他老了,但他看起来很年轻。

Li Li likes violin but doesn't like piano.李莉喜欢小提琴,(但是)不喜欢钢琴。

(but 后面省略了主语Li Li,因为与前面的主语成分相同)Mary likes violin,but Tom doesn't.玛丽喜欢小提琴,而汤姆不喜欢。

(doesn't后面省略了like violin,因为与前面的成分相同)He isn't a teacher but a doctor.他不是(一个)老师,而是医生。

They came here not for money but for the life.他们到这儿来,不是要钱,而是要命。

注意but所连接的句子,句中如果某些成分与前面相同,则可以省略。

4 so,forIt began to rain,so we had to stay here.开始下雨了,我们不得不呆在这儿了。

1.so:所以,因此,于是My teacher asked me to go,so I went.我们老师让我去,因此我就去了。

比较so除了作连词外,也可以作副词。

I hope you can pass the exam.我希望你能通过考试。

I hope so.我也希望。

Don't walk so fast.别走得太快。

2.for:因为I soon went to sleep,for I was tired.我很快就入睡了,因为我太累了。

The sun has risen,for the birds are singing.太阳升起来了,小鸟在唱歌。

比较for和be cause for也可译为“因为”,但是它没有什么因果关系,不像because那样,而for 只是说明解释而已。

5 both…and:和,既……也……He can play both the violin and the piano.他既会拉小提琴,又会弹钢琴。

1.《both…and…》构成的词组作为主语时,谓语动词用复数。

Both Li Ming and Li Li are good students.(Li Ming和Li Li都是人,所以两者对等)李明和李莉都是好学生。

注意在《both…and…》句型中,and连接的词或词组要对等。

2.《both…and》的否定句表示部分否定。

He can't play both the violin and the piano.他会拉小提琴或者会弹钢琴。

(不全会)Both Li Ming and Li Li are not good students.明和李莉不都是好学生。

(其中一个是好学生)6 either…or,neither…norI want to visit either Tianjing or Shanghai.我想参观天津或者上海。

I like neither English nor Chinese.中文和英文我全不喜欢。

1.either…or:或……或……;不是……就是……a.《either…or…》构成的词组作为主语时,谓语动词随其邻近的词,即or后面的词而定。

Either you or he is right.不是你,就是他是对的。

b.此句型的否定句是全否定。

Either you or he isn't right.你和他都不对。

I don't want to visit either Tianjing orShanghai.天津和上海我都不想参观。

2.neither…nor:既不……也不……a.当此词组担任主语时,谓语动词的用法和either…or的用法一样,由nor后面的词而定。

Neither you nor I am right.你和我都不对。

b.此句型本身是全否定,因此不能再用否定式,即不能再加not。

(×)Neither You nor I am not right.比较both …and ,either…or ,neither …nor 这三个句型的相互关系如下:1.肯定句:I like both A and B.我喜欢A和B。

I like both coffee and tea.我喜欢咖啡和茶。

(茶和咖啡我都喜欢)2.否定句:I don't like both A and B. =I like either A or B.我不喜欢A 或B。

I like either coffee or tea .咖啡和茶,我喜欢一样儿。

=I don't like both coffee and tea .3.I don't like either A or B .=I like neither A nor B.A和B 我都不喜欢。

咖啡和茶,我都不喜欢。

I like neither coffee nor tea .I don't like either coffee or tea .7 not only…but also:不但……而且(1)Not only you but also your father is coming.不但你,而且你父亲也要来。

(2)Jane is not only beautiful but also kind.珍妮不但漂亮,而且人非常好。

1.基本用法:《not only…but also》担任主语时,此句型的谓语动词随but also后面的部分而定,参见上文例(1)。

另外not only…but also连接对等的词或词组;例(1)you(你)和your father(你父亲)都是人。

例(2)beautiful(美的)和kind(亲切、慈祥)都是形容词。

2.该句型可以和“as well as”互换,但注意汉语翻译。

Your father as well as you is coming.不但你,而且你父亲也要来。

注意as well as的句子谓语动词随它前面的词“Your father”而定,所以用is coming.Jane is kind as well as beautiful.珍妮不但漂亮,而且为人很好。

2 从属连词常见的从属连词有:(1)引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。

(2)引导条件状语从句的if, unless等。

(3)引导原因状语从句的because, as, since等。

(4)引导目的状语从句的so that, in order that等。
