第3讲 名词性从句
一、名从与连接词
1、名词从句有四类:宾语从句、主语从句、表语从句、同位语从句。例如:
宾语从句:I don’t know where he will go.
主语从句:Where he will go is unknown.
表语从句:The problem is how we can get so much money.
同位语从句:We all feel sorry about the news that he failed in the game.
2、连接词
连接代词:what, which, who, whom, whose, (-ever)
连接副词:how, when, where, why
从属连词:that, whether/if
名词性从句引导词的选择三步骤
1)看从句中缺什么成分, 根据意思选择适当连接词语;缺主宾表连接代词, 缺状语连接副词;
2)如不缺成分且句意完整, 则选用that.
一划:从句
二看:缺少什么成分
三选:意思适合的连接词
二、注意点
1、whether和if 只用whether的情况:介词后, or not, 加to do, 引导主从表从同位语从句
that和what: that:只起连接作用, 不充当任何成分, 不可以省略(宾从的特殊情况除外)what:充当主语、宾语、表语例如:That he got the first place in the competition surprised all of us.
which 在名从中只有缺少“哪一个”意思的时候使用例如:I know which team will win the game.
名从中的虚拟语气: 在“It is suggested/proposed/ordered/a pity/no wonder/necessary/strange/…+that从句”结构中, that从句谓语有时用(should)do这样的虚拟语气形式。
5.常用句型 “The reason why…is that…”例如:The reason why he didn’t go to school yesterday is that he was ill.
6、陈述语序 当一个特殊疑问句本身就是陈述语序(即“主+谓+(宾)”或“主+系+表”结构), 将其变为间接引语(即宾语从句)时, 无需改变语序。例如:What’s the matter with him She asked me what was the matter with him.Who looks after your grandfather He asked me who looked after my grandfather.
同位语从句与定语从句的区别: . 定从:修饰; 同从:解释内容. 定从:that做成分;同从:that不做成分例如:The news that he told me made me happy. The news that he won the first made me happy.
