连词英语语法知识点汇总

连词是一种虚词， 它不能独立担任句子成分而只起连接词与词，短语学习啦在线学习网与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。下面就是小编给大家带来的连词英语语法知识点汇总，希望大家喜欢！

1 并列连词与并列结构

学习啦在线学习网并列连词引导两个并列的句子。

1)　and 与or

判断改错：

学习啦在线学习网(错) They sat down and talk about something.

(错) They started to dance and sang.

(错) I saw two men sitting behind and whisper there.

(对) They sat down and talked about something.

学习啦在线学习网(对) They started to dance and sing.

学习啦在线学习网(对)I saw two men sitting behind and whispering there.

解析：

学习啦在线学习网第一句： and 连接两个并列的谓语，所以 talk 应改为 talked。

学习啦在线学习网第二句：and 连接两个并列的动词不定式，第二个不定式往往省略to，因此sang 应改为 sing。

第三句：and 连接感观动词saw 后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。

学习啦在线学习网注意：and 还可以和祈使句或名词词组连用表示条件。(or也有此用法)

学习啦在线学习网Make up your mind, and you'll get the chance.

= If you make up your mind, you'll get the chance.

学习啦在线学习网One more effort, and you'll succeed.

学习啦在线学习网= If you make one more effort, you'll succeed.

学习啦在线学习网2)　both …and　两者都

She plays (both) the piano and the guitar.

3)　not only…but (also), as well as不但…而且)

学习啦在线学习网She plays not only the piano, but (also) the guitar.

注意： not only… but also 关联两个分句时，一个分句因有否定词not 而必须倒装。

学习啦在线学习网Not only does he like reading stories, but also he can even write some.

4)　neithe…nor 意思为"既不……也不……"谓语动词采用就近原则，与nor后的词保持一致。

Neither you nor he is to blame.

2 比较and和or

学习啦在线学习网1) 并列结构中，or通常用于否定句，and用于肯定句。

2) 但有时and 也可用于否定句。请注意其不同特点：

There is no air or water in the moon.

There is no air and no water on the moon.

在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。

典型例题

学习啦在线学习网---I don't like chicken ___ fish.

---I don't like chicken, ___ I like fish very much.

学习啦在线学习网A. and; and　 B. and; but　C. or; but　D. or;and

答案C。否定句中表并列用or, but 表转折。

判断改错：

(错) We will die without air and water.

(错) We can't live without air or water.

(对) We will die without air or water.

学习啦在线学习网(对) We can't live without air and water.

3 表示选择的并列结构

1) or　意思为"否则"。

I must work hard, or I'll fail in the exam.

学习啦在线学习网2) either…or　意思为"或者……或者……"。注意谓语动词采用就近原则。

学习啦在线学习网Either you or I am right.

4 表示转折或对比

1) but表示转折，while表示对比。

Some people love cats, while others hate them.

典型例题

--- Would you like to come to dinner tonight?

学习啦在线学习网--- I'd like to, ___ I'm too busy.

A. and　 B. so　 C. as　 D. but

答案D。but与前面形成转折，符合语意。而表并列的and， 结果的so，原因的as都不符合句意。

2) not…but… 意思为"不是……而是……"

学习啦在线学习网not 和but 后面的用词要遵循一致原则。

学习啦在线学习网They were not the bones of an animal, but (the bones) of a human being.

5 表原因关系

1) for

判断改错：

(错) For he is ill, he is absent today.

学习啦在线学习网(对) He is absent today, for he is ill.

for是并列连词，不能置于含两个并列分句的句子的句首，只能将其放在两个分句中间。

2) so, therefore

学习啦在线学习网He hurt his leg, so he couldn't play in the game.

注意：

a. 两个并列连词不能连用，但therefore, then, yet.可以和并列连词连用。

学习啦在线学习网You can watch TV, and or you can go to bed.

He hurt his leg, and so / and therefore he couldn't play in the game.

b. although… yet…，但although不与 but连用。

(错)　Although he was weak, but he tried his best to do the work..

(对)　Although he was weak, yet he tried his best to do the work.

6 比较so和 such

其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副

学习啦在线学习网词。so 还可与表示数量的形容词many，few，much， little连用，形成固定搭配。

so + adj.　　　　　　　　　such + a(n) + n.

so + adj. + a(n) + n.　　　such + n. (pl.)

so + adj. + n. (pl.)　　　 such +n. (pl.)

so + adj. + n. [不可数]　　such +n. [不可数]

学习啦在线学习网so foolish　　　　　　　　 such a fool

so nice a flower　　　　　 such a nice flower

学习啦在线学习网so many/ few flowers　　　 such nice flowers

so much/little money.　　　such rapid progress

学习啦在线学习网so many people　　　　　　 such a lot of people

学习啦在线学习网so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能用such搭配。

so…that与such…that之间的转换既为 so与such之间的转换。
