首先要明确所有的从句都是一个句子.而且都有连接词引导,在有些从句中连词可以省略.相应的从句在整个句子中做相应的成分.了解从句之前要了解句子的成分,这里就不赘述. 1.表语从句 在句中作表语的从句叫表语从句.以下两个例句中that引导的为表语从句. The problem is that we don't have enough money. What made us excited is that Liu xiang broke the world record. 2.定语从句 复合句中修饰名词或代词的句子叫做定语从句.以下例句中打括号部分为定语从句 The person over there is the one (who taught me English). The pretty lady (whom you met yesterday) is a famous actress. 3.宾语从句 句子中做宾语的句子叫做宾语从句. He said that he was busy.(that引导的为宾语从句) I don't know who he is.(who引导的为宾语从句) 4.状语从句 句子中做状语的句子叫做状语从句. When he arrived at the airport, the plane had taken off.(when引导的为状语从句) I didn't go to school yesterday because I was ill.(because引导的为状语从句)
主动句和被动句的区别最基本的就是谓语动词的不同.被动句的结构为:be+过去分词 试比较下面两个句子谓语动词的不同: He broke the cup.(主动句) The cup was broken by him.(被动句)
