4、, which , when , where , how , why等。如:Which team will win the match is still unknown .What we need is your help .第2页共35页How he became a famous musician is known to all .主语从句做主语, 句子显得不太平衡, 因此常将它移到名子后面, 前面用引导词 it 来作形式主语。如:It s a pity that she had made such a mistake .2 .表语从句:用作表语的从句叫表语从句。如:That is why

5、 I didnt attend the meeting .I didn t know it.

6、at,连接副词 how ,when , where等。如:The idea that computers will recognize human voices surprises many people .第3页共35页The possibility that the majority of the labour force will work at homeis often discussed .注意同位语从句同定语从句的区别:1 ) 同位语从句的连接词 that 在从句中不充当成份,没有实际含义,而定语从句的连接词 that 在从句中常做主语或宾语。如:The news that he

7、told us just now is exciting .(定语从句 )The news that our team won the game is exciting .(同位语从句 )2 ) 同位语从句的连接词 that 在从句中不能省略,而定语从句的连接词 that 如果在从句中充当宾语,可以省略。如:The news that he told us just now is exciting .句中的 that在从句中做 told的直接宾语,所以可以省略。3 ) 同位语从句常用连接词 that , 连接副词 when , where 等常用于 have no ( some ) idea

8、后。如: I have no idea when he will be back . ( 同位语从句 ) = I don t know when he ll be back .第4页共35页I will never forget the day when I joined the army .(定语从句 )【 指点迷津】very误用例析1 . 误 I m very afraid hes out . 正 I m very much afraid hes out . 析 very不能修饰 afraid , asleep , awake , alone , alive等表语形容词,这类形容词要用其他
