高中英语语法解析 ‎ 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。 名词性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、介词宾语等，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 ‎　　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。被强调部分指人时也可用who/whom。例如：‎ ‎ a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。‎ ‎ b) It doesn’t interest me whether you succeed or not.　我对你成功与否不感兴趣。‎ ‎ c) It is in the morning that the murder took place.　谋杀案是在早上发生的。（强调句型）‎ ‎ d) It is John that broke the window.　是John打碎的窗户。（强调句型）‎ ‎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…‎ ‎ It appears that… 似乎…‎ ‎(4) It ＋ 过去分词 ＋ 从句 ‎ It is reported that… 据报道…‎ ‎ It has been proved that… 已证实… ‎ ‎ It is said that… 据说…‎ ‎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：‎ ‎ 正确表达：It is said that President Jiang will visit our school next week. ‎ ‎ 错误表达：That President Jiang will visit our school next week is said. ‎ ‎（3）It happens/occurs…结构中的主语从句不可提前。例如：‎ ‎ 正确表达：It occurred to him that he failed in the examination. ‎ ‎ 错误表达：That he failed in the examination occurred to him. ‎ ‎（4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如：‎ ‎ 正确表达：It doesn’t matter whether he is wrong or not. ‎ ‎ 错误表达：Whether he is wrong or not doesn’t matter. ‎ ‎（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： ‎ ‎ 正确表达：Is it likely that it will rain in the evening? ‎ ‎ 错误表达：Is that will rain in the evening likely?‎ ‎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：‎ ‎ a) What you said yesterday is right.‎ ‎ b) 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. 我听说他参军了。‎ ‎ (2) 由what, whether (if) 引导的宾语从句，例如：‎ ‎ a) She did not know what had happened.　她不知道发生了什么。‎ ‎ b) I wonder whether you can change this note for me.　我想知道你是否 ‎ 能帮我改一下笔记。‎ ‎ (3) 动词＋间接宾语＋宾语从句。例如：‎ ‎ She told me that she would accept my invitation.　她对我说她会接受我的 ‎ 邀请。‎ ‎2. 作介词的宾语 ‎ Our success depends upon how well we can cooperate with one another.　我们的成功取决于我们之间的合作。‎ ‎3. 作形容词的宾语 ‎ I am afraid (that) I’ve made a mistake.　我恐怕我已经犯了一个错误。‎ 注意：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. 我听说她下个朋就会结婚了。‎ ‎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。如：‎ ‎ 正确表达：I admire their winning the match. ‎ ‎ 错误表达：I admire that they won the match.‎ ‎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：‎ ‎ 正确表达：He impressed the manager as an honest man. ‎ ‎ 错误表达：He impressed the manager that he was an honest man.‎ ‎7. 否定的转移 ‎ 若主句谓语动词为think, consider, suppose, 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）‎ ‎ ‎ ‎ ‎ 第二章 “It”用法及其句型和固定搭配讲解 ‎　　"It" 用法及其句型和固定搭配，是高中英语语法的重点、难点，又是近几年高考的热点，因此应给予充分的重视，现将it用法归纳如下：‎ ‎　　一、It用作实词 ‎　　表达以下概念:指代前文提到的事物，前文中的this, that；替代前文中的内容；指代一位性别不明的小孩或未知的人；指代未指明但谈话双方都知道的那件事；指代时间、天气、气候、距离等自然现象…… ‎ ‎ 二、It用作形式主语 ‎ ‎　　替代作主语的从句、动词不定式、动名词，而把真正作主语的从句、动词不定式、动名词置于句尾。 ‎ ‎ It 作形式主语的常见句型： ‎ ‎ ‎ ‎1. 代作主语的动词不定式，其句型为 ‎ ‎ (1) It be adj. (for sb.) to do sth. ‎ ‎ 此处adj. 通常为描述事件的形容词：easy, difficult, hard, necessary, unnecessary, possible, impossible, likely, unlikely, right, wrong, important, unimportant, legal, illegal, well-mannered, ill-mannered, polite, impolite, clear, obvious, certain, suitable, proper, fit, useful, useless, dangerous… ‎ ‎ 例 It is illegal (for a teenager) to drive a car without a license. ‎ ‎ (2) It be adj. of sb. to do sth. ‎ ‎ 此处adj. 通常为描述人的形容词：kind, unkind, nice, rude, cruel, considerate, thoughtful, thoughtless, careful, careless, silly, foolish, stupid, clever, wise, crazy. ‎ ‎ 例 It's kind of you to help me with the problem. ‎ ‎ (3) It替代作主语的动名词的常见句型 ‎ ‎ It's no good/use doing… ‎ ‎ It's (well)worth doing… ‎ ‎ It's (well)worth one's while doing/to do… ‎ ‎ It's (well)worth while doing/ to do ‎ ‎ 例 It's no use crying over spilt milk. ‎ ‎ ‎ ‎2.

( whom不可以省) 汤姆病倒了，你昨天见到他了。 ‎ ‎2）在口语和非正式用语中，关系副词when ,where , 和 why 经常用that 来代替，甚至还可省略。如：‎ ‎ a) This is the first time (when/that)he had trouble with the boss.这是他第一次麻烦老板。 ‎ ‎ b) He wants to find a good place (where/that) we can have a picnic during the “golden week ”holiday .他想找一个能在黄金周期间野餐的好地方。‎ ‎ c) Could you tell us the reason (why/that)he was so unhappy ? 你能告诉我们他为什么如此不高兴吗？‎ ‎3）当先行词为表示方式的 the way 时 ，从句不能用 how 来引导 ，应该用that 或 in which ，或将它们全部省略。如： ‎ ‎ I don't like the way (that/in which) you laugh at her.我不喜欢你嘲笑他的行为。 ‎ ‎3．宾语从句中的省略 ‎1）在及物动词后面所接的宾语从句中，连词that 一般可以省略；但如果及物动词后面是由that引导的两个或两个以上的并列的宾语从句 ，那么只有第一个that可以省略。如：‎ ‎ a) I think (that) the reform of the renminbi's exchange rate is necessary. 我认为人民币兑换率的改革是必要的。 ‎ ‎ b) He said (that)the Anti-secession law had been passed and that President Hu Jintao had signed a presidential order 他说《 反分裂国家法》已被通过，而且胡锦涛主席已签署了主席令。‎ ‎2）由 which , when ,where , how,和 why 引导的 宾语从句，可以全部或部分省略。如： ‎ ‎ a) I know that NBA star Yao Ming will come to our city but I don’t know when (he will come to our city).我知道NBA明星要到我们城市来但我不知道他什么时候来。‎ ‎ b) He wants to move abroad but his parents wonders why (he wants to move abroad)他想搬迁到国外但他的父母想知道为什么。 ‎ ‎4．在与suggest ,request ,order ,advise 等词相关的名词性从句中，须用虚拟语气形式“should +动词原形”，should可以省略。如： ‎ Chirac, President of the Republic of France suggested that the China-France Culture Year (should) last long in various forms.法国总统希拉克建议中法文化年以各种各样的形式长期持续。 ‎ ‎5．主句省略多用于句首。如：‎ ‎ (It is a ) Pity that I didn’t go to Mary's birthday party yesterday.很遗憾，我昨天没有去参加玛丽的生日聚会。‎ ‎6．在答语中，主句可全部省略。如：‎ ‎ —Why were you absent from school last Friday ?—(I was absent from school)Because my mother was ill. —上周五你为什么没有上学？ —因为我妈妈病了。 ‎ ‎ ‎ 三、动词不定式to 的省略 ‎ ‎1．主语部分有to do ,系动词 is 或 was 时 ，作表语的不定式通常省去to。如： ‎ ‎　The only thing you have to do is press the button.你必须做的惟一事情是按按钮。 ‎ ‎2．作介词but ,expect ,besides 的宾语，前面又有实意动词 do时，不定式通常省去to. 如：‎ ‎　He said that Chen Shuibian had nothing to do except push a pro-“independence” timetable.他说陈水扁除了推进支持“独立”的时间表外，什么也没有做。 ‎ ‎3．主语部分暗含to do，表语中的不定式通常省去to。如：‎ ‎　All I want (to do) is go to school and study hard .我想要（做）的就是上学，努力学习。 ‎ ‎4．当两个或多个不定式并列时，其后的不定式符号可以省略，但有对比关系时不可省略。如：‎ ‎　It is easier to say than to do . 说起来容易，做起来难。‎ ‎5．在would rather…than… 等结构中，不定式符号常常要省略. 如：‎ ‎　I would rather stay at home than go to see a film.我宁愿呆在家也不愿去看电影。 ‎ ‎6．在see ,watch ,notice ,hear, listen to ,look at ,feel ,have, make, let ,observe 等词后作宾语补足语时省略不定式符号to；why (not) do 结构 中, 不定式不带to。如：‎ ‎　a) I saw her enter the room. 我看见她进入了房间 ‎ ‎　b) Why not join us ?为什么不加入到我们的行列里来呢？ ‎ 四．其他一些省略结构 ‎ ‎1．名词所有格修饰的名词，若表示住宅、店铺、教堂或上下文已暗示或明确指出过的事物时，常常可以省略。如：‎ ‎　We spent the weekend at the Mary's.　我们在玛丽家过的周末。 ‎ ‎2．What和 how引导的感叹句中，常可省略主语 it 和be动词 如：‎ ‎ a) What a wonderful victory (it is ) for Tom ! 这对Tom来说是个多么大的胜利呀！‎ ‎ b) How beautiful (it is ) to be treated like a normal child. 被当作一个正常孩子对待对他而言是多么美妙的一件事呀。‎ ‎ ‎
