如何判断主从复合句和并列复合句？

## 学生提问 After the 1870's, a number of important authors began to reject the romanticism that had prevailed immediately following the Civil War of 1861-1865 and turned instead to realism. 老师，这句句子可以是并列复合句嘛？ 连接词：and 主句1：After the 1870's, a number of important authors began to reject the romanticism that had prevailed immediately following the Civil War of 1861-1865 主句2：After the 1870's, a number of important authors turned instead to realism. 答案说是主从，但感觉并列也可以吧。 ## 权威解答 并列复合句的定义是，两个或者以上的子句之间是并列关系。你找的这两个子句，主语只有一个，都是 a number of important authors ，都是一个主语，也就是只有一套主谓结构，也就是一个子句咯。 I am a teacher and love gym. 这是一个主谓结构，并列谓语，一个主语； I am a teacher and I love gym. 这是两套主谓结构，是并列复合句。 ## 知识点梳理 （一）并列复合句 并列复合句含有两套或者更多相互并列的主谓结构的句子。 ① Water has weight; air has weight too, but it is very light. ② Heat is energy, so is electricity. （二）主从复合句 含有两套或更多的主谓结构，其中有一个是主要的主谓结构，其他主谓结构从属于它并且担任起句子成分。 ① They believe that the computer will finally take the place of human beings. ② He asked me where he could get such medicine. （三）简单句 简单句就是只含有一个主谓结构并且句子各成分都只由单词或短语构成的独立句子或分句。在简单句中主语和谓语是句子的主干，是句子的核心。 ① I found the book easy. ② My sister will fix everything.
