6、不充当任何成分,但不能省略。,That he will win is certain.他肯定会赢。 she was chosen made us very happy.她当选了使我们很高兴. Whether hell come here isnt clear. 他是否会来这里还不清楚。,That,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 l

7、ike 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

8、 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 Its 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 eff

9、ective.,+(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 t

11、ise,It is reported that,It is suggested that,2.连接代词who ,what ,which, whatever, whichever, whoever what既有引导主语从句的作用,同时又在从句中作句子成分(主语、宾语、表语等).这时what相当于all that/everything that.,常译成所的(东西、事情、话等.) What many scientists believe is that the earth is round What is done cant be undone. (谚语)已成定局,无可挽回. What we ca

12、nt get seems better than what we have.我们得不到的东西似乎比已得到的要好.,(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),Who will take part in the meeting has not been decided. Whoever breaks the law will be punished. Which student will win is uncertain. Whateve

14、ided.,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 Mar

15、y 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 )hasnt been decided yet.,2.(_ they will arrive )has been told to the teacher.,4.(_ can join in the sport meet) is
