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： 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，例如： 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，例如： 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. 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） 高一英语名词性从句专项练习 1．____he does has nothing to do with me.

More than one student was late. 不只一个学生迟到 More persons than one come to help us. 不止一个人来帮助我们。 7. none 做主语时,谓语动词可用单数, 也可用复数; 但在代表不可数的东西时总是看作单数,因而谓语动词要用单数. 如: None of us are (is) perfect. 人无完人。 None of this worries me. 这事一点不使我着急。 8. 名词如: trousers, scissors, clothes, goods, glasses 等作主语时, 谓语动词必须用复数. 如: His clothes are good. 但这些名词前若出现 a pair of , 谓语一般用单数.如: A pair of glasses is on the desk. 桌上有一副眼镜。 9. 形复意单名词如:news ; 以ics 结尾的学科名称如: physics, mathematics, economics; 国名如: the United States; 报纸名如: the New Times; 书名如: Arabian Night <天方夜谈>; 以及The United Nations<联合国> 等作主语时, 谓语动词用单数。 10. “a +名词+and a half “, “one and a half + 名词”, “the number of + 名词” 等作主语时, 谓语动词要用单数. 如: Only one and a half apples is left on the table. 注意: one or two + 复数名词作主语, 谓语动词用复数形式, 如: One or two places have been visited. 参观了一两个地点。 (二) 内容一致原则: 1.主语中有all, half, most, the rest等, 以及”分数或百分数+名词”做主语时,谓语动词单复数取决于连用的名词.如: The rest of the bikes are on sale today. 剩下的自行车， 今天出售。 60%of the apple was eaten by little boy. 这个苹果的60%都被这个小男孩吃了。 Most of the apples were rotten. 大部分的苹果都是烂的。 Most of the apple was eaten by a rat. 这个苹果的大部分被老鼠吃了。 2. 不定数量的词组, 如:part of , a lot of , lots of , one of , a number of , plenty of等作主语时, 谓语动词的单复数取决于量词后面名词的数.如: A part of the textbooks have arrived. 一小部分教科书已运到。 A part of the apple has been eaten up by the pig. 这个苹果的一部分被猪吃光了。 3. 加减乘除用单数.如: Fifteen minus five is ten . 15减去5等于10。 4. 表示时间, 金钱, 距离, 度量等的名词做主语时, 尽管是复数形式, 它们做为一个单一的概念时, 其谓语动词用单数.如: Ten miles is a good distance. 十英里是一个相当的距离。 5.

(三) 就近原则 1. 由here, there, where 等引导的倒装句中, (有时主语不止一个时)谓语动词与靠近它的主语在数上一致.如: Here comes the bus 公共汽车来了. Here is a pen and some pieces of paper for you. 给你一支钢笔和几张纸。 Where is your wife and children to stay while you are away? 你不在这儿的时候, 你爱人和孩子在哪儿呆呢？ 2. 用连词or, either.... or, neither….nor, not only….but also 等连接的并列主语, 谓语动词与靠近它的主语在数上一致。 如： Neither the students nor the teacher knows anything about it 学生和老师都不知道这事. He or you have taken my pen. 他或你拿了我的钢笔。 注意: one of +复数名词+who/that/which 引导的定语从句中, 定语从句的动词为复数。如： Mary is one of those people who keep pets. 玛丽是饲养宠物者之一。 The only one of +复数名词+ who/that./which 引导的定语从句中，定语从句的动词应为单数。 Mary is the only one of those people who keeps pets. 玛丽是唯一一个饲养宠物的人。 主谓一致练习 1.

It's for sb.和 It's of sb. 1) for sb. 常用于表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等： It's very hard for him to study two languages. 对他来说学两门外语是很难的。 2) of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。 It's very nice of you to help me. 你来帮助我，你真是太好了。 for 与of 的辨别方法 用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如：You are nice. (通顺，所以应用of)。He is hard. (人是困难的，不通，因此应用for。) 4. 不定式作表语 不定式可放在be动词后面，形成表语。例如： My work is to clean the room every day. His dream is to be a doctor. 5. 不定式作定语 不定式做定语通常要放在被修饰的词后。例如： I have a lot of work to do.

He searched the room only to find nothing. 3) 表原因 I'm glad to see you. 典型例题 The chair looks rather hard, but in fact it is very comfortable to ___. A. sit B. sit on C. be seat D. be sat on 答案：B. 如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。 用作介词的to to 有两种用法：一为不定式+动词原形； 一为介词+名词/动名词, to 在下面的用法中是第二种，即to+ 名词/动名词：admit to承认，confess to承认，be accustomed to 习惯于，be used to 习惯于，stick to 坚持，turn to开始，着手于，devote oneself to 献身于，be devoted to 致力于， look forward to 盼望，pay attention to 注意 省to 的动词不定式 1) 情态动词 ( 除ought 外，ought to)： 2) 使役动词 let, have, make： 3) 感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作宾补，省略to。 注意 在被动语态中则to 不能省掉。 I saw him dance. =He was seen to dance. The boss made them work the whole night.=They were made to work the whole night. 4) would rather，had better： 5) Why… / why not…： 6) help 可带to，也可不带to, help sb (to) do sth： 7) but和except：but前是动词do时，后面出现的动词用不带to的动词不定式。 8) 由and, or和than连接的两个不定式，第二个to 可以省去： 9) 通常在discover, imagine, suppose, think, understand等词后，可以省去to be：He is supposed (to be) nice. 他应该是个好人。举例：He wants to move to France and marry the girl. He wants to do nothing but go out. 比较：He wants to do nothing but go out. He wants to believe anything but to take the medicine. 典型例题 1) ---- I usually go there by train. ---- Why not ___ by boat for a change? A. to try going B. trying to go C. to try and go D. try going 答案：D. why not 后面接不带to 的不定式，因此选D。 2) Paul doesn't have to be made ___. He always works hard. A. learn B. to learn C. learned D. learning 答案：B. make后接不带to 的动词不定式，当其用于被动时，to 不可省略。 动词不定式的否定式 Tell him not to shut the window… She pretended not to see me when I passed by. 我走过的时候，她假装没看见。 典型例题 1) Tell him ___ the window. A. to shut not B. not to shut C. to not shut D. not shut 答案：B。 tell sb to do sth 的否定形式为tell sb not to do sth. 2) She pretended ___ me when I passed by.

A. not to B. not to do C. not do it D. do not to 答案：A。not to 为not to do it 的省略形式。可以只用to这个词，而不必重复整个不定式词组。及物动词do后应有名词、代词等，否则不对，因此B，D不对。 5) The patient was warned ___ oily food after the operation. A. to eat no B. eating not C. not to eat D. not eating 答案：C。warn一词要求后用不定式，此处为不定式的被动，否定形式为be warned not to do。 不定式的特殊句型too…to… 1) too…to 太…以至于… He is too excited to speak. 他太激动了，说不出话来。 ---- Can I help you ? 需要我帮忙吗? ---- Well, I'm afraid the box is too heavy for you to carry it, but thank you all the same. 不用了。这箱子太重，恐怕你搬不动。谢谢您。 2) 如在too前有否定词，则整个句子用否定词表达肯定， too 后那个词表达一种委婉含义，意 为"不太"。 It's never too late to mend.

A. turning it off B. turn it off C. to turn it off D. having turned it off 答案：C。由the light is still on 可知灯亮着，即关灯的动作没有发生，因此用forget to do sth. 而forget doing sth表示灯已经关上了，而自己忘记了这一事实。此处不符合题意。 remember doing/to do remember to do 记得去做某事 (未做) remember doing 记得做过某事 (已做) Remember to go to the post office after school. 记着放学后去趟邮局。 Don't you remember seeing the man before? 你不记得以前见过那个人吗? regret doing/to do regret to do 对要做的事遗憾。 (未做) regret doing 对做过的事遗憾、后悔。 (已做) I regret to have to do this, but I have no choice. 我很遗憾必须这样去做，我实在没有办法。 I don't regret telling her what I thought. 我不为告诉她我的想法而后悔。 典型例题 ---You were brave enough to raise objections at the meeting. ---Well, now I regret ___ that.
