并列句
并列句是由两个或两个以上的简单句并列组合而成的句子,中间由连词连接。连词是一种虚词,不能独立作句子成分。我们已学过的and,but,or,so(so 也可作连接副词)等都是并列连词,用于表示并列、转折、选择、因果等关系。
考点1 并列连词的使用
1. and表示并列、顺承或递进关系。 连接的成分可以是单词、短语或句子。
· I like reading, and my sister likes writing.
我喜欢阅读,我姐姐喜欢写作。
· He is smart and kind. 他既聪明又善良。
2. but表示转折关系。
· She is rich but not happy. 她很富有,但不开心。
· The story is short but interesting. 这个故事很短,但很有趣。
3. or表示选择关系。也可用于“祈使句 + or + 陈述句”结构,表示“否则”。
· You can choose the red one or the blue one.
你可以选择红色的那个或者蓝色的那个。
· Study hard, or you will fail the exam.
努力学习,否则你会考试不及格。
4. so表示因果关系。用于连接一个原因和它所导致的结果。
· It rained heavily, so we decided to stay at home.
雨下得很大,所以我们决定待在家里。
· There are many ways to solve this problem. So, we need to choose the most suitable one. 解决这个问题有很多方法。 所以,我们需要选择最合适的一种。
考点2 并列句的结构类型
(1)常见“简单句 + 并列连词 + 简单句”的结构。连词前一般用逗号(也可以不用)。
· She likes painting, and she often goes to the art museum on weekends. 她喜欢绘画,并且她经常在周末去美术馆。
· He ran fast, but he still didn’t win the race.
他跑得很快但还是没赢得比赛。
(2)简单句+连接副词+简单句 (注意连接副词前一般用分号)
· I want to buy a new bike, however, I don’t have enough money.
我想买一辆新自行车,然而,我没有足够的钱。
· He finished his work; then he went home immediately.
他完成了工作,然后立刻回家了。
考点3 并列句的注意事项
1. 当并列句的主语相同时,后面句子的主语可以省略。
· He opened the door and (he) walked into the room.
他打开门,走进房间。
· He should study harder or (he) risk failing the course.
他应该更努力学习,否则有挂科的风险。
2. 并列句中,各分句的时态一般要保持一致,但在实际语境中,如果表达不同时间发生的动作,时态也可以不同。
· He worked hard in the past, but now he is very lazy.
他过去工作很努力,但现在他非常懒。
· I study English every day, so I will pass the exam easily.
我每天学习英语,所以我将很容易通过考试。
