专题 02 连词 and、but 和 because 的用法
语法精讲
连词and、but和 because的用法
用来连接词与词、短语与短语，以及句子与句子的虚词叫做连词。连词在句中不能单独
作句子成分，一般不重读。连词按照性质可分为两类：并列连词和从属连词。
本单元学了三个连词 and、but和because。其中and、but属于并列连词，because属于从
属连词。
1.and
表示并列、顺承等关系，意为“和；并且；而且”；作并列连词，可以连接并列的单词、
短语或句子；意为“那么，于是”时，可根据具体语境进行翻译，也可不译，起承上启下的
作用。
Drive slowly and carefully.小心，慢点开车。
Come here and you can have a good time.来这里吧，你会玩得开心。
拓展：or，表示选择关系，意为“或者”。
You can come on Saturday or Sunday. 你可以周六来，也可以周天来。（连接单词）
You can go fishing with us, or you can just stay at home. 你可以和我们一起去钓鱼，也可以就待
在家里。（连接句子）
This is an apple. And what's that?这是一个苹果。那是什么？
【名师提醒】
在否定句中要把and变为or。
I like apples and oranges.（改为否定句）
I don't like apples or oranges.我不喜欢苹果和橙子。
2.but
表示转折关系，意为“但是”；用来引出相反意见或不同情况。连接两个并列的成分或
句子时，语气较强，在意义上构成明显的对比。与前半句可用（可不用）逗号分开，与后半
句不用逗号分开。
The woman is old， but she looks very young.（与前半句可用逗号分开）
这位女士老了，但是她看起来很年轻。
Mike has a basketball but he doesn't have a baseball.迈克有一个篮球，但他没有棒球。

转折连词，意为“但是”，连接两个并列的成分，表示前后意义
but
的转折或两种情况的对比
并列连词，意为“和；又；而”，连接并列的单词、短语或句
and 子，表示顺承或并列关系。连接两个名词或代词作主语时，若指
两人或两物，谓语动词用复数形式

He can play the guitar and he can sing,too.他会弹吉他，并且也会唱歌。
3. because
①回答why引导的特殊疑问句，后跟句子，申述原因或理由。
②引导原因状语从句，表示直接原因，原因构成句子的最主要部分。
-Why are you late？你为什么迟到了？
-Because I got up late.因为我起晚了。
Because I am very busy, I can't go out with you.
=I am very busy, so I can't go out with you.
因为我太忙了，所以我不能和你一起出去。
【名师提醒】
在汉语中，表示因果关系一般用“因为······所以······”，但在英语中，because（因为）与
so（所以）不能同时出现在一个句子中。
