英语名词性从句用法系统归纳

2、re was discovered.(复合句)二、从句的种类复合句的各个组成部分在句中的地位不是同等重要的，其中，相对重要的部分是主句(Main Clause )而相对次要的部分是从句(Subordinate Clause )o从句分为三种类型：副词从句(AdverbialClause),即状语从句,在整个复合句中相当于副词的作用；名词从句(NounClause),包括主语从句(Subject Clause )、宾语从句(Object Clause )、表 语从句(Predicative Clause )和同位语从句(Appositive Clause ),在整个复合句中都相当于名 词的作用；

3、形容词从句(Attributive Clause),即定语从句，在整个复合句中相当于形容词的作用。三、主句和从句的区分可以按照以下步骤进行主句和从句的区分：找出所有谓语；找出所有连接主句和从句的连词；例如：1.从句是由关联词和从属连词引导的，从句的结构是关联词/从属连词+主语+谓语+其他成分. 主句是主语+谓语+其他成分.I dont konw the place where he lives*where是从属连词,where he lives是状语从句.i don't konw the place是主句.四、高考英语语法考点：名词性从句语法归纳种类关联词例句说明主语从句连 词that
