高中英语语法：It的完整用法精讲 打印版
高中英语语法：It的完整用法精讲 it可用作人称代词、指示代词、先行词及引导词等。 1. 人称代词it，是第三人称单数中性，代表前文已提到过的一件事物。如： 1）That vase is valuable. It's more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 2）I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 当说话者不清楚或无必要知道说话对象的性别时，也可用it来表示。如： 3）It's a lovely baby. Is it a boy or a girl? 宝宝真可爱，是男孩还是女孩？ it可用来指代团体。如： 4）The committee has met and it has rejected the proposal. 委员会已开过会，拒绝了这项建议。 it用以代替指示代词this, that.如： 5）--- What's this? --- It's a pen. —这是什么？—是一支钢笔。 6）--- Whose book is that? --- It's Mike's. —那是谁的书？—是迈克的。 2. 指示代词it，常用以指人。如： 7）Go and see who it is. 去看看是谁。 8）--- Who is making such a noise? —是谁发出这样的吵闹声？ --- It must be the children. —一定是孩子们。 3.虚义it无指代性，常用作没有具体意义的主语，出现于表示天气、气候、温度、时间、地点、距离等意义的句子中。如： 9）It is half past three now. 现在是三点半钟。 10）It is six miles to the nearest hospital from here. 这里离最近的医院也有六英里。 11）It was very cold; it snowed and grew dark. 天气很冷；天下着雪，渐渐地变黑了。 it也常用来表示一般的笼统的情况。如： 12）It's awful—I've got so much work I don't know where to start. 糟透了——我有这么多工作要做我不知从何开始。 13）How is it going with you? 你近况如何？ 14）Take it easy. 不要紧张。 it也常用于下列结构： 15）It looks as if the college is very small. 看起来这个学院很小。 16）It seems as though our plan will be perfect. 似乎我们的计划很完善。 17）It's my turn. 该轮到我了。 it也常用于某些习惯用语中作宾语，各该习惯用语有具体意义，但it并无具体意义。如：cab it 乘车catch it 受责，受罚come it 尽自己分内come it strong 做得过分walk it 步行make it 办成take it out of somebody 拿某人出气 4. 先行词it. it充当形式主语或形式宾语，本身无意义，只起一种先行引导的作用，先行词不重读。后面的真正主语或真正宾语通常是不定式结构、-ing分词结构或名词性从句。 （1）用作形式主语
高中英语语法最重要知识汇总
按：本套资料省去了名词、代词、形容词等部分，保留了最最核心的句型和动词。希望能有所帮助。 第一章名词性从句 在句子中起名词作用的句子叫名词性从句。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 …; It is an honor that…; It is common knowledge that… (2) It is ＋形容词＋从句 It is natural that…It is strange that… . (3) It is ＋不及物动词＋从句 It seems that…It happened that…It appears that… (4) It ＋过去分词＋从句 It is reported that…It has been proved that…It is said that… 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：
高中英语新高考语法基础版一轮复习讲义(9)被动语态知识点整理总结(含练习与解析)
2021届高中英语新高考语法基础版一轮复习讲义（9） 被动语态知识点整理总结 被动语态是中高考经常考的语法之一，也是日常口语和写作中必不可少的句子形式，今天笔者就带大家一起来学习它。 01 被动语态的概念 所谓被动语态是相当于主动语态而言的。如果主语是动作的执行者，那么我们就称其为主动语态，反之，如果主语是动作的承受者或动作的对象，那我们就称其为被动语态。如： 主: Many people speak Chinese. 被: Chinese is spoken by many people. 02 被动语态的结构 被动语态由"be＋及物动词的过去分词"构成。人称、数和时态的变化是通过be的变化表现出来。下面通过speak来说明常见时态的被动语态：一般现在时 am/is/are＋spoken 一般过去时 was/were＋spoken
一般将来时 will/shall be＋spoken 现在进行时 am/is/are being＋spoken 过去进行时 was/were being＋spoken 现在完成时 have/has been＋spoken 过去完成时 had been + spoken 03 被动语态的执行者 被动语态的执行者一般以by+人/物来引出。如果没有执行者或没必要说出执行者，则可以省略这部分。如： Some computers were stolen last night. 无法确定执行者，因此无by结构。 The glass was broken by Mike.
执行者是Mike，所以这里用by引出。 04 含有情态动词的被动语态 用“情态动词＋be＋过去分词”结构。 如： We can repair this watch in two days. This watch can be repaired in two days. 05 特殊情况主动变被动 make/let+sb+do变为被动要还原to。如： He made the boy work for two hours a day. The boy was made to work for two hours a day. 双宾语结构的物做被动语态主语时，后面要还原出介词。如：Jack gave Peter a present just now. A present was given to Peter just now. 巩固练习 1.

It 作形式主语与ｉt引导强调句得比较 It 作形式主语代替主语从句,主要就是为了平衡句子结构,主语从句得连接词没有变化、而i ｔ引导得强调句则就是对句子某一部分进行强调,无论强调得就是什么成分,都可用连词that。被强调部分指人时也可用who/ｗｈｏｍ、例如: ａ) It isａpitｙｔhaｔyoｕｄidn’t go ｔo seｅｔhｅｆilm.您不去瞧那场电影真可惜。 b) It doeｓn’tｉntereｓt me whethｅrｙou sｕｃceed or not、我对您成功与否不感兴趣、 c) Ｉｔisｉn thｅｍoｒnｉng thaｔｔｈe ｍurder took place. 谋杀案就是在早上发生得、(强调句型) d) Ｉt is Joｈn tｈat broke ｔｈeｗｉｎdow。就是Joｈn打碎得窗户。(强调句型) 2、用ｉt 作形式主语得结构 (1)It is + 名词＋从句 It is ａfaｃt tｈat…事实就是… Ｉt ｉs an honor ｔhat …非常荣幸 It ｉｓｃommon knowlｅdge ｔhat …就是常识 (2)Ｉt is + 形容词+从句 It is naturａl thａt…很自然… It ｉｓstrａｎｇe that…奇怪得就是…(3) It ｉｓ＋不及物动词+ 从句 Ｉｔｓｅems thａｔ…似乎… Ｉt ｈappeneｄthat…碰巧… Iｔappeaｒs that…似乎…
高中英语语法知识之It的用法总结
高考英语语法知识之It 的用法总结 1．It is + 被强调部分+ that ... 该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，状语。强调的主语如果是人，that可以由who换用。 如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was not until + 被强调部分+ that ... 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3．It is clear ( obvious, true, possible,certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定．．．）＂是主语从句最常见的一种结构。 It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉．．．）＂。It is said that he has come to Beijing. 6. It is suggested ( ordered ... ) that ... 主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为＂据建议；有命令．． It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) that ... 该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing ( should ) happen in your class. It is a pity that he is ill. 8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。常译为＂是（正是）．．．的时侯．．．＂。 It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ... ) time that ... 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人第几次做某事了＂。 It is the first time I have been here. = This is the first time I have been here. 10 It is the +形容词最高级+ 名词+ that + ….. 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人做过的最…的事情＂。 This is the best film that I have ever seen . That was the worst song that he had heard . 11. It is .... since ...
高考英语语法复习讲义：语法总结全集
语法总结全集 名词和主谓一致 一、名词的分类 英语中名词主要可以分为可数名词和不可数名词。 1．可数名词 可数名词一般都有单复数。单数时，名词前可加不定冠词a/an；复数时，前面可加数词，名词本身要改成复数形式。 可数名词的复数有规则和不规则两种变化。规则的名词，只要在单数名词之后加“s”，“es”或去“y”加“ies”就行，如：an umbrella, twelve umbrellas；a factory, three factories。不规则的名词变化则要靠积累记忆，如：a mouse, ten mice；a policeman, six policemen。 有少数可数名词，如sheep，works（工厂），Chinese等，它们的单复数同形：a sheep, four sheep；a chemical works, five chemical works。 此外，还有一些可数名词只有复数形式，如clothes，trousers，cattle，police，people(人，人民)等。 英语名词中还有一些合成词，它们的复数形式有三种可能：1）后面的部分变成复数形式：grown-ups，boy students，grandchildren。2）前面的部分变成复数形式：passers-by，lookers-on，sons-in-law。3）前、后都变成复数形式：men doctors，women drivers。 2．不可数名词 不可数名词没有单复数的变化，前面也不能加a/an，或数词。但是我们可以用量词来表示不可数名词的数量，单复数表现在量词上，如：a piece of paper；two pieces of paper。 在有些情况下，不可数名词也可用a/an，表“一种”、“某种”的意思，如have a wonderful time，receive a good education，be made into a fine paper。 有时为了表示量大，不可数名词的后面也可加“s”，如sands，ashes，waters等。 但是我们在学习不可数名词的时候，特别要记住英语中有一些名词，它们无论在什么情况下，前面都不能用a/an，后面也不可加“s”，如weather，information，等。 3．有的名词既可是可数名词，也可是不可数名词 英语中有相当一部分的名词，既可以是可数，也可以是不可数，它们的意义有时略有不同，有时则完全不同。如：difficulty, success, time, work，paper，glass，等。 4．用于表示可数与不可数名词的数量“多”“少”的常用词和词组 跟可数名词连用的如：few, a few, many。 跟不可数名词连用的如：little, a little, much。 可数与不可数都能用的是：a lot of , plenty of。 二、主谓一致 1．通常被看作单数的主语部分 1）不定式、动名词和主语从句。 eg.. To see is to believe. Seeing is believing. What he said was different from what he did. 2）表示“时间”“距离”“金钱数量”的名词。 eg. Twenty years is quite a long time. 10 kilometers doesn’t seem to be a long distance to Mira. 300 dollars is too much for this old coin.
高中英语语法总结大全-形容词和副词
高中英语语法大全之形容词和副词 形容词及其用法 形容词修饰名词，说明事物或人的性质或特征。通常，可将形容词分成性质形容词和叙述形容词两类，其位置不一定都放在名词前面。 1)直接说明事物的性质或特征的形容词是性质形容词，它有级的变化，可以用程度副词修饰，在句中可作定语、表语和补语。例如：hot 热的。 2)叙述形容词只能作表语，所以又称为表语形容词。这类形容词没有级的变化，也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如：afraid 害怕的。 （错）He is an ill man. （对）The man is ill. （错）She is an afraid girl. （对）The girl is afraid. 这类词还有：well，unwell，ill，faint，afraid，alike，alive，alone，asleep，awake 等。 3）形容词作定语修饰名词时，要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时，要放在这些词之后，例如： something nice 以-ly结尾的形容词 1）大部分形容词加-ly可构成副词。但friendly，deadly，lovely，lonely，likely，lively，ugly，brotherly，仍为形容词。 改错：(错）She sang lovely. （错）He spoke to me very friendly. （对）Her singing was lovely. （对）He spoke to me in a very friendly way. 2）有些以-ly 结尾既为形容词，也为副词。 daily，weekly，monthly，yearly，early The Times is a daily paper. The Times is published daily. 用形容词表示类别和整体 1）某些形容词加上定冠词可以泛指一类人，与谓语动词的复数连接。如：the dead，the living，the rich，the poor，the blind，the hungry The poor are losing hope. 2）有关国家和民族的形容词加上定冠词指这个民族的整体，与动词的复数连用。 the British，the English，the French，the Chinese. The English have wonderful sense of humor. 多个形容词修饰名词的顺序 多个形容词修饰名词时，其顺序为： 限定词--数词--描绘词--(大小，长短，形状，新旧，颜色) --出处--材料性质，类别--名词 a small round table a tall gray building
高中英语语法讲义——特殊句式
高中英语语法讲义————特殊句式 倒装句 通常句式为自然语序“主语+谓语”，有时为了强调句子的某一部分，或者出于词汇用法、语法结构或修辞上的需要，将这种比较固定的语序加以颠倒，就形成了倒装。分为完全倒装，部分倒装和形式倒装。 一.完全倒装：谓语动词完全置于主语之前，主语为名词不为代词，谓语不用进行时。 1.一些表示地点、时间或方位等的副词或介词短语。如：here, there, now, then, up, down ,in, out, away, off, in the room, on the wall等置于句首。 Down came the rain and up went the umbrella. Then followed three days of heavy rain. Out rushed the children laughing loudly. Away flew the plane. 2.such 位于句首。 Such was Albert Einstein, a simple man and the 20th century’s greatest sci entist. 注：此句型中的such多被认为是表语，所以such后的be动词应与其后真正的主语保持一致。 Such are the facts; no one can deny them. 二．部分倒装：只把谓语的一部分（助动词，情态动词或be动词）置于主语之前 1.so+ be 动词/ 助动词/ 情态动词+主语，意为“...也是如此”。 They love making lots of friends; so do I. 2.neither/nor+ be动词/助动词/情态动词+主语，意为“...也不这样”。 Lily can’t ride a bicycle; neither/nor can Lucy. 3.否定词never, seldom, nor, not, little, hardly, scarcely等或表示否定意义的介词短语at no time, under/in no circumstances, in no case, by no means, on no condition 等置于句首时。 Not a single mistake did he make. =He di dn’t make a single mistake. 4.only 修饰副词、介词短语或状语从句，且放在句首时。 Only then did I begin to understand him. Only in this way can we solve the problem. Only if you work hard will you be admitted to a top university. 5.so...that...和such...that...句式中，so或such及其所修饰的部分置于句首时，主句用部分倒装。 So clearly does he speak English that he can always make himself understood Such progress did he make that he won much respect. 三．形式倒装：在语法上称为前置。只把强调的内容提至句首，主谓并不倒装。 1.感叹句 What an interesting talk they had! =How interesting a talk they had! 2.the+比较级.....,the +比较级.....句型 The more you listen to English, the easier it becomes. 3.whatever+ n.或however+ adj./adv.引导的让步状语从句 Whatever reasons you have, you should carry out your promise. However difficult the problem may be, we must work it out this evening. 4,as / though引导让步状从，表语、状语、含情态动词的谓语提前，表语为单数名词提前不用冠词。 Young as /though he was, he was successful. Child as /though he is, he knows much.
