and, but, or都是连词,我们在使用这几个连词的时候要弄清楚所连接成分之间的关系。下面请大家来看一张表格:

概念
    

    and作连词时,意思是“和”,可以连接并列的词、短语或句子,表示并列、附加或递进的关系; but是表示转折关系的连词,连接前后两个句子时,常意为“可是;但是”,不能够与though / although 在句中同时出现;or作连词,表示“或者”,通常用在表示完全否定的句中连接所列举的人或物,如果使用and则表示的是半否定的意义,也可以用在表示选择的疑问句中连接供选择的部分。
例句

and

1. Tom and Jack are my friends. (连接并列的词)
2. The boy has a small nose and two big eyes. (连接并列的短语)
3. My father is a worker and my mother is a nurse. (连接并列句)
4. Work hard, and you will catch your classmates. (表示递进)

but

1. He is ill, but he comes to school on time. (连接相反意义的句子)
2. The bike is small but expensive. (连接省略主语相反意义的部分)

or

1. Hurry up, or you'll be late. (表示假设的结果)
2. It has no eyes or ears. (完全否定句中连接的并列部分)
3. You can go there by bus or by car. (表示选择)
小结 1. 所连接的两个句子主语相同时,后一句的主语可以省去;
2. 所连接的两个句子主语、谓语都相同时,后一句的主语、谓语都可以省去。
