连词在句中不能单独作句子成分,只起连接作用,要连接平等的结构,即连接词与词、短语与短语或句子与句子。连词分为并列连词和从属连词。

并列连词

并列连词用来连接具有平行关系的词、短语或句子。常用的并列连词有:and,but,or,so,both…and,not only…but also,either…or,neither…nor等。

1.and “和,而且”,连接主语时谓语动词用复数。

My brother and I are students. 我哥哥和我都是学生。

2.or “和,或者”,表示选择,多用于否定句。连接主语时谓语动词由后者决定。

I don't like milk or coffee. 我不喜欢牛奶和咖啡。

3.but “但是”,表示转折。

I can swim, but I can't swim well. 我会游泳,但我游得不好。

4.so “所以,因此”,表示结果。

It's raining outside, so I have to stay at home. 外面下雨了,所以我只好待在家里。

5.both...and “两者都……”,连接主语时谓语动词用复数。

I can speak both Chinese and English. 我会说汉语和英语。

6.not only...but also “不但……而且”,连接主语时谓语动词由后者决定。

Not only he but also I like skating. 不但他而且我也喜欢滑冰。

7.either...or “或者……或者”,表示选择。连接主语时谓语动词由后者决定。

Either she or I have the chance to go abroad. 要么她要么我有机会出国。

8.neither...nor “既不……也不”,连接主语时谓语动词由后者决定。

Neither she nor I like Sports Shows. 她和我都不喜欢体育节目。

从属连词

从属连词用来连接主句和从句。常用的从属连词有:when,before,after,as soon as,because,if,though,although等。

1.when/while “当……时”,表示时间,引导时间状语从句。

When I got home, my mother was cooking. 当我到家的时候,妈妈正在做饭。

2.before “在……之前”,表示事情发生的先后顺序,引导时间状语从句。

I must get home before 5:00. 我5点之前必须到家。

3.after “在……之后”,表示事情发生的先后顺序,引导时间状语从句。

After I had breakfast, I went to school. 我吃完早饭后上学去了。

4.as soon as “一……就……”,表示时间,引导时间状语从句。

As soon as I get home, I will call you. 我一到家就给你打电话。

5.because “因为,由于”,表示原因,引导原因状语从句。

She isn't at school because she is ill. 因为她生病了,所以没上学。

6.if “如果”,表示条件,引导条件状语从句。

You will make progress if you work hard. 如果你努力就会取得进步。

7.though/although “虽然,尽管”,表示让步,引导让步状语从句。

Although/Though he is rich, he is unhappy. 虽然他很有钱,但是他不快乐。

在汉语中“因为……所以……”总是成对出现,

而在英语中because 不能和so 并用,二者只用其一。

Because I like music. I often go to concerts.

I like music. So I often go to concerts.

因为我喜欢音乐,所以我经常去听音乐会。
