小学英语语法:并列句(3)
叫一辆出租车,否则你将错过这列火车。
Study hard, or you Will fall behind the others.努力学习,否则你就会落于别人。
(2)“祈使句+and+简单句”。其中祈使句表示一个条件,并列连词and引导的简单句则表示一个较好的结果,谓语常用一般将来时。
Use your head, and you will find a good idaal.动脑筋,你就会想出办法来。
Work hard, and you’ll pass the exam.
(=If you work hard, you’ll pass the exam.)
努力学习,你就会通过考试。
4. 表示因果关系的并列句
这类并列句常用并列连词for,so等连接前后简单句。
(1)for在意义上与从属连词because,since和as相同,但它们引导的是原因状语从句,而for则连接两简单句,前者表示结果,后者表示原因。其结构为:简单句(结果)+for+简单句(原因)。
He has many good friends, for he is an honest man。他有许多好朋友,因为他是个诚实的男子汉。
She didn’t come to school today, for she was ill. 今天她没来上学,因为她生病了。
(2)so意为“因此”、“所以”,但不能与because同时出现在同一个句子中。因为because是从属连词引导的是原因状语从句,而so是并列连词,用来连接并列句。其结构为:简单句(原因) +so牛简单句(结果)。
Mr. Li went to his hometown, so Mr. Wang was taking his class instead.李老师回家乡去了,所以王老师替二课。
The shop doesn't open until
11 a.m., so it loses a lot of business.
