  主语从句:

  做主语用的名词性从句,因其在复合句中做主语,又称主语从句,引导主语从句的有连词that ,whether, 连接代词who ,what ,which, 连接副词when,where, how, why等。

  1)从属连词:that, whether等. that 引导主语从句只起引导作用,本身无实际意义,在主语从句中不充当任何成分,但不能省略。

  That he will win is certain.他肯定会赢。 Whether he’ll come here isn’t clear.

  他是否会来这里还不清楚。

  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 of advice is impossible. _______________________________________

  _______________________________________

  2.That they should like each other is natural.

  _____________________________________

  *it为形式主语 It is natural that they should like each other. It is impossible that he will refuse this piece of 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 common knowledge that… …是常识

  *_______________(很遗憾)we lost 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 possible that...

  很可能……

    It is unlikely that...

  不可能……

  It is obvious that… 很明显…

  It is necessary important natural... that…

  *_________________(很可能)she will come back tomorrow. *_________________(很明显)this measure is effective. +(should) +do… It is possible that It is obvious that 3) It +不及物动词+从句

  It happened that...

  碰巧……

  It occurred to me that…我突然想起…

  *________________(刚好)I came into the office at that time.

  *____________________(我突然想起)I forget to sent the letter. It happened that It occurred to me that 4) It + be +过去分词+从句

  It is said that...

  据说……

  It is known to all that...

  众所周知……

  It is reported that...

  据报道……

  It is believed that...据信……;人们相信……

  It is suggested that + (should)do... 建议…… It must be admitted that…必须承认……

  It cannot be denied that… 不可否认…… It must be pointed out that…需指出的是……  

  *___________________(据报道)20 people were killed in the accident.

  *______________________(建议)we should eat more vegetable and do more exercise.

  It is reported that It is suggested that 2.连接代词who ,what ,which, whatever,

  whichever,

  whoever (Who, whom, which, what可以和ever构成合成词,和what一样引导从句,ever起到强调作用。此类主语从句不能用形式主语it引导,它们在句子中担任成分,不能省略,语序为陈述语序)

  What many scientists believe is that the earth is round … Who will take part in the meeting has not been decided. Whoever breaks the law will be punished. Which student will win

  is uncertain. Whatever was said here must be kept secret.

  这里说的话都应当保密。

  Whoever makes mistakes must correct them.

  凡犯了错误的人都必须改正。

  3)连接副词when,where, how, why等。 Why they suddenly disappeared still remains a mystery. When they will leave is not decided. Where she is from is unknown. How we will paint the house has not been decided.

  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。 误:They should like each other is natural. 正:That they should like each other is

  natural. 正:It is natural (that) they should like

  each other. 2)如果主语从句放在句首,不能用if引导,但是如果用it 做形式主语,而把主语从句放在句末时,也可以用if引导. 或把if 改为whether

  误:If Mary really heard him is really doubtful. 正:It was doubtful if Mary really heard him. 正: Whether Mary really

  heard him is really

  doubtful.

  Complete the sentences using what, whether, where,

  when, who, why, how or that. 1.(_____ is needed for success) is your hard work. 3.(_____ we will go tomorrow )hasn’t been decided yet. 2.(______ they will arrive )has been told to the teacher. 4.(______ can join in the sport meet) is decided by the teacher. 5.(________ it will rain or not) is not clear. What When/How Where/whether Who Whether 主语从句作主语时,谓语动词一般用单数形式。 Conclusion: 主语从句的规律: 找出下列句子中的错误,并总结规律 例1.When will he come is not known. 规律一、主语从句一律用陈述语序,

  即主语在前,谓语在后。 正:When he will come is not known. 主语从句的规律: 例2. He will not come to the meeting

  this evening is true. 正:That he will not come to the

  meeting this evening is true. 规律二、连词that 在从句中无实际意义,

  但不能省略。 主语从句的规律: 例3.

  If the meeting will be put off

  has not been decided yet. 正: Whether the meeting will be put off

  has not been decided yet. 规律三、whether 可以引导主语从句,

  放在句首,但if不能 主语从句的规律:

  例4. That whether he will help others

  is a fact. 正:That he will help others is a fact. 规律四、主语从句中的连词不能重叠使用。 主语从句的规律: 例5. When he will come are a puzzle. 正:When he will come is a puzzle. 规律五、含主语从句的主句谓语动词多用

  单数第三人称形式。 主语从句的规律: 1. What he needs is that book.

  2. What he needs are some books. 规律六、what 引导的主语从句,可根据

  表语决定主句动词的单复数形式。 规律七、主语从句为了避免头重脚轻现

  象,用 it 做形式主语,而

  把从

  句放在后面。

  That the earth turns around the sun

  is known to all.

  It is known to all that the earth turns

  around the sun. 找出错误,并给出理由: 1.Where shall we spend the holiday isn’t decided.
