【知识梳理】
并列连词and, but, or和so
并列连词是一种虚词,它不能独立担任句子成分,而只起连接词与词、短语与短语或句子与句子的作用。并列连词包括:表平行或对等关系的连词and,表转折关系的连词but,表选择关系的连词or和表示因果关系的连词so等。
1. and表示并列,意为“和;并且”,用于连接形容词、副词、名词、动词或句子。如:
He played the guitar and sang folk songs. 他弹起了吉他,且唱起了民谣。
【拓展】“祈使句 + and + 陈述句”表示条件与结果,可与句型“If条件句 + 主句”互换使用。
如:Study hard and you can pass the exam. = If you study hard, you can pass the exam.
(如果你)努力学习,你就可以通过考试。
2. but表示转折,意为“但是”,用于连接前后内容不同或意思相反的单词、短语或句子。须注意:but与though或although不能同时用于同一个句子中。如:
It is a nice dress, but it creases very easily.
= Though/Although it creases very easily, it is a nice dress.
虽然它很容易起褶子,但这是一条不错的裙子。
3.or用来表示选择关系,意为“或者”。
如:Do you like this pen or that pen?你喜欢这支钢笔还是那支钢笔?
What would you like, tea or coffee?你喜欢茶还是咖啡?
【拓展】or用于否定句中表示并列,表示“也不,也不是,也没有”。
如:I don't like singing or dancing.我不喜欢唱歌,也不喜欢跳舞。
【拓展】“祈使句 + or + 陈述句”,or表示“否则”、“要不然的话”。
如:Hurry up, or you will be late for school. 快点,否则你上学会迟到。
4.so表示结果,意为“所以”,用于连接前后有因果关系的句子。
须注意:so与because不能同时用于同一个句子中。如:
There was a long queue in the duty-free shop, so I almost missed my flight.
= Because there was a long queue in the duty-free shop, I almost missed my flight.
因为免税店的排队太长了,我几乎错过了我的航班。
