高中英语各种复合句精品课程讲解 （英语尖子生培训课 什么叫名词性从句？ 在句子中起名词作用的句子叫名词从句 (Noun Clauses） 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句 【一】主语从句 【二】表语从句 【三】宾语从句 【四】定语从句 【五】同位语从句 【六】状语从句 【一】主语从句：在主句种充当主语成分的从句叫主语从句， 引导主语从句的连词有：从属连词；连接代词；连接副词 A 从属连词：that，whether。 从属连词；that，whether引导的主语从句在主语从句中不充当任何成分,只起连接词的作用，通常不可以省略。分句置于句首时，that绝对不可以省略。如果是由It作形式主语，后面that可以省略. 1,有that 引导的主语从句如下： 1. That the driver could not control his war was obvious. =It was obvious（that）the driver could not control his car. 2. That she was chosen made us very happy. =it made us very happy that she was chosen 3. That he is still alive is sheer luck. 他还活着全靠运气。 =It is sheer luck that she is still alive 4. That the whole project is doomed to failure is quite clear =It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。 5. That you should have to leave is a pity =It's a pity that you should have to leave. 你非走不可真是件憾事。 6. That he will refuse this piece of advice is impossible. =It is impossible that he will refuse this piece of advice 7. That they should like each other is natural =It is natural that they should like each other 8. That he will not come to the meeting this evening is true =It is true that he will not come to the meeting this evening 9. That he will help others is a fact 10. That the earth turns around the sun is known to all. =It is known to all that the earth turns around the sun. 11. That we can win is certain =It is certain that we can win. 12. That you have made a mistake is a fact. =It is a fact that you have made a mistake 13. It is ordered that we should leave at once. 14. That you don’t like him is none of my business. 用it作形式主语的that-从句有以下四种不同的搭配关系： a. It + be +形容词+ that-从句 It is necessary that… 有必要…… It is important that… 重要的是…… It is obvious that… 很明显…… It’s certain that… 肯定… It is possible that... 很可能…… It is unlikely that... 不可能…… It is necessary \important \natural\... that… It is possible that she will come back tomorrow. It is obvious that this measure is effective. b. It + be +V ed 分词+ that-从句 It is known to all that… 从所周知…… It has been decided that… 已决定…… 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…… It was reported that 20 people were killed in the accident. It was suggested that we should eat more vegetable and do more exercise c. It + be +名词+ that-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 common knowledge that… …是常识 It is common knowledge that… 是常识 It is a fact that… 事实是…… It was a pity that we lost the match. It was a fact that he cheated in the exam. d. It +不及物动词+ that-分句 It appears that…似乎…… It happens that…碰巧…… It occurred to me that…我突然想起…… It occurred to me that I forgot to send this letter It happened that I came into the office at that time. It is important(necessary / advisable / desirable / imperative / true / strange / possible ...)that ...需要注意的是,这类主语从句中,谓语动词很多为"(should)＋动词原形",即要用虚拟语气。例如: It is necessary that several nurses (should) stay. 几个护士留在这儿是很有必要的。 It is imperative that everyone (should) learn from practice. 每个人都应该从实践中学习。 It is reported (well-known / hoped / thought / expected / said / believed / decided / suggested / ordered ...)that ...例如: It is said that many people was killed in the earthquake. 据说很多人在这次地震中丧生了。 it seems(appears / doesn’t matter / makes no difference / ...)that ... 例如: It makes no difference whether he will attend the meeting or not. 他是否会参加会议都无关紧要。 当用it作形式主语,而将主语从句放在句尾时,主语从句中的否定词常要前移至主句中。例如: It doesn’t seem that they are from the same university. It doesn’t appear that we’ll have a sunny day tomorrow. if 不能用在主语从句中，而是用whether，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 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. Whether he left (or not) is unknown Whether he will come is not clear. Whether it will rain or not) is not clear Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。 Whether we will go tomorrow )hasn’t been decided yet Whether the meeting will be put off has not been decided yet. Whether the policeman will come is not certain. Whether the 2000 Olympic Games will be held in Beijingis not known yet. Whether we’ll go camping tomorrow depends on the weather. whether he likes the job is not clear. .注意区分it 作形式主语的主语从句与强调句 强调句句型It is/was+被强调部分+that, 去掉It is/was, that，句子仍然成立。 It is natural that they should have different views. 主语从句 It is only lately that he had had a family himself. 强调句 What was it that he wanted? I don’t know what it was that he wanted. It was in the hotel where he stayed that we discussed the serious problem 8.注意it 作形式主语的主语从句和as引导非限制性定语从句引导的不同 It is known to all that the earth is round. As is known to all. the earth is round. B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。 What is needed for success) is your hard work. Who can join in the sport meet) is decided by the teacher What he needs is that book. What he needs are some books. What he needs are some books. Who he is and where he is from are important. What he saw are the stars in the sky What he said at the meeting astonished everybody present Whoever leaves the room last ought to turn off the lights. C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. When they will arrive has been told to the teacher Where we will go tomorrow hasn’t been decided yet When he will come is not known When he will come is a puzzle Where we shall spend the holiday isn’t decided. Where he comes from is a mystery. Conclusion:主语从句作 主语时，谓语动词一般用单数形式 主语从句的规律 规律一、主语从句一律用陈述语序，即主语在前，谓语在后。 规律二、连词that 在从句中无实际意义，但不能省略。 规律三、whether 可以引导主语从句， 放在句首，但if不能 规律四、主语从句中的连词不能重叠使用 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。 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，把从句放在后面。
名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。例如： It is a pity that you didn’t go to see the film. It doesn’t interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is ＋形容词＋从句 It is natural that… 很自然… It is strange that… 奇怪的是… (3) it is ＋不及物动词＋从句 It seems that… 似乎… It happened that… 碰巧… (4) it ＋过去分词＋从句 It is reported that… 据报道… It has been proved that… 已证实… 3. 主语从句不可位于句首的五种情况 (1) if 引导的主语从句不可居于复合句句首。 (2) It is said , (reported) …结构中的主语从句不可提前。例如： It is said that President Jingo will visit our school next week. (right) That President Jiang will visit our school next week is said. (wrong) (3) It happens…, It occurs… 结构中的主语从句不可提前。例如： It occurred to him that he failed in the examination. (right) That he failed in the examination occurred to him. (wrong) (4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如： It doesn’t matter whether he is wrong or not. (right) Whether he is wrong or not doesn’t matter. (wrong) (5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如： Is it likely that it will rain in the evening? (right) Is that will rain in the evening likely? (wrong) 4. What 与that 在引导主语从句时的区别 What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如： 1) What you said yesterday is right. 2) That she is still alive is a consolation. 二．宾语从句 宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。 1. 作动词的宾语 (1) 由that引导的宾语从句（that 通常可以省略）,例如： I heard that be joined the army. (2) 由what, whether (if) 引导的宾语从句，例如： 1) She did not know what had happened. 2) I wonder whether you can change this note for me. (3) 动词＋间接宾语＋宾语从句。例如： She told me that she would accept my invitation. 2. 作介词的宾语 例如：Our success depends upon how well we can cooperate with one another. 3. 作形容词的宾语 例如：I am afraid (that) I’ve made a mistake. That 引导的从句常跟在下列形容词后作宾语： Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。 4. It 可以作为形式宾语 It 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如： We heard it that she would get married next month.. 5. 后边不能直接跟that 从句的动词 这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。例如： I admire their winning the match. (right) I admire that they won the match. (wrong) 6. 不可用that从句作直接宾语的动词 有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如： He impressed the manager as an honest man. (right) He impressed the manager that he was an honest man. (wrong) 7. 否定的转移 若主句谓语动词为Think, consider, wuppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如： I don’t think this dress fits you well.（我认为这件衣服不适合你穿。） 三．表语从句 表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语＋连系动词＋表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如： 1) The question is whether we can make good preparation in such a short time. 2) This is why we can’t get the support of the people 3) But the fact remains that we are behind the other classes. 4) The reason he is late for school is that he missed the early bus. 四．同位语从句 同位语从句就是在复合句中作名词的同位语的名词性从句。 1. 同位语从句的功能 同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如： 1) The king’s decision that the prisoner would be set free surprised all the people. 2) The order that all the soldiers should stay still is given by the general. 2. 同位语在句子中的位置 同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如： He got the news from Mary that the sports meeting was put off. 3. 同位语从句与定语从句的区别 (1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。 (2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如： 1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语） 2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）
大家都知道，诚实是最好的政策 (policy)
不需要哦，因为knowledge这里是不可数名词，common knowledge解释为常识。不能加a的 knowledge可表示“了解,知道”或“知识,认识,学问”等,是不可数名词。有时在knowledge前可直接加上不定冠词a,表示“对…有某种程度的了解或熟悉”。 例如： She has a detailed knowledge of this period. 她对这段时期的情况了解地相当详细。 knowledge后可接of短语作定语或that从句作同位语,表示关于某方面的知识或对某人〔某事物〕的了解或理解,此时knowledge前须加定冠词。 knowledge可用some, much, little, more等词修饰。
