OLevel考试之中,OLevel语法既是基础又是难点,所以我们在备考中要多多备考、练习,在语法中复合句是非常常见的考点。想要提高OLevel语法成绩,今天我们就来讲讲复合句的知识点!
复合句介绍
复合句(Complex Sentence)分为并列复合句和从属复合句,并列复合句是有并列连词:and、or、but连接;从属复合句由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause)构成。用疑问词作引导词,主句是全句的主体,通常可以独立存在;从句则是一个句子成分,不能独立存在。从句不能单独成句,但它也有主语部分和谓语部分,就像一个句子一样。所不同在于,从句须由一个关联词(connective)引导。 根据引导从句为主不同大大可分为:主语从句、表语从句、宾语从句、定语从句、状语从句等。
复合句可分为:
1).定语从句(The Attributive Clause);
2).状语从句(The Adverbial Clause);
3).名词性从句(The Noun Clause);
