Appsitive Clause（同位语从句）
Object Clause（宾语从句）
Predicative Clause（表语从句）
名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。
Wh will win the match is still unknwn. I want t knw what he has tld yu. The fact is that we have lst the game. The news that we wn the game is exciting.
名词性从句的作用相当于名词，因此主语从句、表语从句 、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。
Cnjunctins f Nun Clauses(引导名词性从句的关联词):
what, wh, whm, whse, which, wh+ever
that, whether, if ,as if/as thugh
when, where, hw, why
主语从句就是从句在主句中作主语的名词性从句。
1)That she left him hurts him s much. 2)Whether it will please them is nt easy t say.3) What we need is mre practice.4)When we will begin the meeting is under discussin.
*that —只起引导作用，不充当成分，但不能省略。
*whether 是否，表不确定的事情(不能用If）
*what 在从句中作主语
*When 在从句中作状语
*______________________________(他是否要来)is nt yet knwn.*_____________________________(他想告诉我们什么)is nt clear.*___________________________(谁会赢得这场比赛)is still unknwn. *_______________________________(你错过了这次机会)is a pity. =It is ___________________________________.
Exercise 1:
Whether he will cme r nt
What he wants t tell us
Wh will win the match
That yu missed the chance
a pity that yu missed the chance
注意: 由that 引导的主语从句有时为了使句子结构平衡, 避免 “头重脚轻”, 常用 it 作形式主语, 而把从句放在后面。 例如:
1. That he will refuse this piece f advice is impssible._______________________________________ 2.That they shuld like each ther is natural. _____________________________________
It is natural that they shuld like each ther.
It is impssible that he will refuse this piece f advice.
这样就构成了下面一些常用句型: 1) It is + n. +从句 　 It is a pity/shame that... 遗憾的是…… 　 It is a surprise that…令人惊奇的是…　 It is a fact that… …是事实 It is cmmn knwledge that… …是常识*_______________(很遗憾)we lst the match.*______________(这是事实)he cheated in the exam.
It is a pity that
It is a fact that
2) It is + adj. +从句 　 It’s certain that… 肯定… 　 It is pssible that... 很可能…… 　 It is unlikely that... 不可能…… It is bvius that… 很明显… It is necessary \imprtant \natural\... that…*_________________(很可能)she will cme back tmrrw.*_________________(很明显)this measure is effective.
+(shuld) +d…
It is pssible that
It is bvius that
3) It +不及物动词+从句 It happened that... 碰巧…… It ccurred t me that…我突然想起…*________________(刚好)I came int the ffice at that time.*____________________(我突然想起)I frget t sent the letter.
It happened that
It ccurred t me that
4) It + be +过去分词+从句 It is said that... 据说…… It is knwn t all that... 众所周知…… It is reprted that... 据报道…… It is believed that... 据信……;人们相信…… It is suggested that + (shuld）d... 建议…… It must be admitted that… 必须承认…… It cannt be denied that… 不可否认…… 　　 It must be pinted ut that…需指出的是…… 　*___________________(据报道)20 peple were killed in the accident. *______________________(建议)we shuld eat mre vegetable and d mre exercise.
