1、作主语
To learn a foreign language is not easy.
It is not easy to learn a foreign language.
2、作宾语
They began to read.
3、作宾语补足语
Jim asked me to help him with his lessons.
We often heard her sing.
4、作定语
I have an important meeting to attend.
引导宾语从句的词有:
连词that(在口语中that常可省略),if,whether,如:
He knows that Jim will work hard.
连接代词who,whom,which等,如:
Do you know who (whom) they are waiting for?
连接副词when,where,how,why等,如:Could you tell me how we can get to the station?
结合具体语境
语法中很多是抽象的概念,囫囵吞枣地去记忆往往让人觉得索然无味。所以千万不要孤零零地去记忆语法,要把语法规则和一定的上下文或者生活语境结合起来。
这样一来,语法就变得真实可感了。另外,语法就像是从树干上长出的树枝一样,都是相互关联的,可以画一些图示来帮助记忆。
复合句
例如:A、Thenews that our team has won the match is true (同位语从句)B、The news that he told us surprised everybody here。
(定语从句)关键的区别在于连接或关系代词that:有意义的是定语,无意义的是同位。因为引导定语从句的that在从句中作主语或宾语,而引导同位语从句的that只起到连接词的作用。
