注意: (1)从句作主语谓语动词常用单数,但如果 what 引导的从句作主语,后跟名词作表语 时,谓语动词则由表语名词的数量决定。 What he told me is true. 他告诉我的是真的。 What he saw were some new comers. 他看见的是些新来的人。
(2)It is said that sb.do sth.的复合句形式可转化为简单句sb.be said to do sth., 而且在简单句中常考查 to do 的具体形式。 (3)it 引导的强调句与 it 作形式主语的复合句的区别。 it 引导的强调句是用来对句中除谓语外某一成分加以强调,其结构为“It is/was+ 被强调部分+that/who...”。如果被强调的主语是“人”,则可用 who 或 that, 如果被强调的部分是其他成分时,必须用 that。 It was I that/who met John in the street yesterday. 是我昨天在街上遇到了约翰。(强调主语) It is a pity that you didn't go to see the film. 你没去看电影很可惜.ppt
演讲人
1.主语从句位于句首。 Who kept the door open all night was unknown. 不知道是谁让门整晚开着。 2.主语从句位于句尾,使用it作形式主语。 it作形式主语置于句首的结构 (1)“It+be+形容词+that clause”结构,常用于这种句型的形容词有: fortunate,possible,(un)likely,strange,probable,true,certain等。 It is strange that no one wants to go there. 真奇怪,竟然没有人想要去那里。

It is certain that she will do well in her exam. It is true that I told her everything.
It is said that Mr. Green has arrived in Beijing. It is reported that China has sent another manmade earth satellite into orbit.
2)连接代词who ,what ,which, whatever, whichever, whoever
充当成分,有具体意义
What seems easy to some people seems difficult to others. Which side will win is not clear.
主语从句常用it作形式主语放句首
因而我们常见到这种句式: It+be+n./adj/-ed从句(that,
whether,etc.) 例:It's a pity that you should have
to leave. = That you should have to leave is a pity. It is great that I have a teacher like you. = That I have a teacher like you is
注意:
1)主语从句在句首时,必须由连接词引导, 不能省略这些连接词;但是如果用it做形式 主语,而把主语从句放在句末时,从属连词 that可以省略。
4) . 用于It is important / natural / necessary / impossible that...句型中, 主语从句应使用虚 拟语气, 谓语动词用\“should + 动词原形\”的 形式, should有时可以省略。
“How do you do?” is a greeting. What she said is not yet known. That we shall be late is certain. It is certain that we shall be late.
主语从句 (Noun Clauses as the Subject)
It doesn’t matter whether she will come or not.
It makes no difference where we shall have the meeting.
3) It +及物动词(被动语态)+主语从句
It has been decided that the exhibition will not open on Sundays.
2.位置: 主语从句可以前置,也可以 后置。用it做形式主语,而把主语从 句,在句末,常用下面几种句型。
1)It + be + 表语 +主语从句 表语:(名词, 形容词,过去分词)
It is a fact (a shame, a pity, good news…) that…
It is still uncertain whether he is coming or not. It is an honour that I was invited to attend the meeting.
3)连接副词when,where, how, why等。
Why he did it remains a mystery. When they will start is not known yet. How he became a great scientist is known to us all.
Noun Clauses ---The subject clause
By Debby
Grammar
What part does the underlined part serve as in each sentence?
A tree has fallen across the road. You are a student. To find your way can be a problem. Smoking is bad for you.
定义: 用作主语的从句叫主语从句,它是名
词性从句之ቤተ መጻሕፍቲ ባይዱ。引导主语从句的连接词有:
连词that, whether;连接代词who, what和which;连接副词when, where, how和why。
主语从句的连接词
1.连词 that(无 词 义 , 不 作 成分 , 不 能 省 略);whether(是否),if不能位于句首。
5) 在It + be+suggested/advised/ordered/requested/ insisted/required 中, that从句的谓语也应 该用\“should + 动词原形\”的形式, should有 时可以省略。
3. 主语从句需注意的问题 (1)主语从句中用陈述语序 What she is afraid of is their taking her to Paris. ( What is she afraid of … Wrong ) (2)主语从句后谓语动词用三人称单数 That they haven’t phoned is strange.
2)It+不及物动词+主语从句 It seemed (happened, doesn’t matter, has turned out) that…
It happens that they were absent. It seems that Alice is not coming to the party at all.
2.That he will come and help us is certain. 3.Whether we will succeed is still a
question. 4.It is not known if he will come.
注意: 已确定的事由that引导; 没决定的事由whether引导.
