高中英语中it用法小结20条
1.It is+被强调部分+that 该句型是强调句型，将被强调的放在前面，其他部分置于之后，(强调的主语如果是人，可以用who来替换that)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他从句的方法。(如果强调的是动词就要用到do的各种形式)It was they that(who)cleaned the classroom yesterday.---Where did you buy the apples?
----It was on the farm where we worked.(True)----It was on the farm that we worked.(False)2.It is not until +被强调的部分+ that 该句型译成汉语“直到„„才”
It was not until she took off her dark glasses that I realized she was a film star.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结构。It is very clear that he’s round and tall like a tree.4.It is important(necessary, right, strange, natural…)that…
该句型和上一句同属一个句型。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。建议记住该句型中的形容词。It is important that we(should)learn English well.It is necessary that he(should)remember these words.5.It is said(reported, learned, believed …)that…
该句型中的it 仍是形式主语，真正的主语是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.It is reported that another earth satellite has been put into orbit.6.It is suggested(ordered…)that… 该句型和上一句属一个句型。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）。可以省略，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 …
在该句型中，that后的从句一般用虚拟语气（should+动词原形），should可以省去，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.这种事竟然发生在你们班上，真是遗憾。
It is a pity that he is ill.他生病了，真遗憾！
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：常用过去时态表示虚拟，有时也用should+动词原形，should 不能省。常译为“是（正是）„„的时候„„” 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…
该句型应和上一个句型区别开来。该句型中不用虚拟语气，而用完成时态。至于用哪种完成时态，由主句的谓语动词的时态来决定。如果是一般现在时，从句用现在完成时态；如果是一般过去时，从句则用过去完成时态。该结构中that可以省去；it有时用this替换，常译为“是第一（二,„）次„”。10.It is …since…
该句型主要用作处理瞬间动词的完成时，要和表示一段时间的时间状语连用。主句中是时间作表语，其时态是现在时和完成时，引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。It is(has been)5 years since his father died.11.It is …when…
该句型中的when引导的是一个时间状语从句，主句中的it指时间，表语由具体的时间充当。常译为“当„„的时候，是„„” It was 5 o’clock when he came here.12.It be…before…
该句型主句中的it指时间，主句中的时态常是一般将来时或过去时两种时态，主句中的表语多是long ,not long ,3 days, 2 weeks等表示时间段的词和短语。常译为“„之后才”，“没过„„就„„” It was 3 days before he went to Beijing.13.It happens(seems, looks, appears)that…
该句型中的it 是形式主语，that 引导的是主语从句，主句中的happen, seem等词是不及物动词。
It happened that he met his teacher in the street.(碰巧„„)It seems that he will be back in a few days.(看来„„)14.It takes sb …to do sth.该句型中的不定式是真正的主语，是形式主语，句型中的直接宾语是时间。常译为“做„„要花费某人„„”
It took thousands of people many years to build the Great Wall.15．It is no good(use)doing sth.该句型中的真正主语是动名词短语，主句中的表语可以是 no good(not any good)，no use(not any use).It is no good learning English without speaking English.16.It doesn’t matter whether…
该句型中的引导的从句是真正的主语，该句型译为“不论（是否）„„没关系„„ It doesn’t matter whether they are old.17．It is kind(of sb)to do sth.该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由of引出，主句中的形容词必须是能表示逻辑主语的形容词。常见的有：bad, brave, careless, clever, cruel, foolish good(好心的),honest, horrible, kind, lazy, modest, naughty, nice(有教养的),polite, rude, silly, stupid ,wise ,wrong等。这个句型可以改写为sb.is kind to do sth.It is kind of you to stay so =You are kind to say so.18.It is necessary(for sb)to do sth 该句型与上一句统属一个句型。如果不定式的逻辑主语是由for 引出的，主句的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。常见的形容词有：
Important,necessary,natural,easy,safe,common，normal,hard,difficult,dang erous,unusual, grape, impossible, pleasant.等。
It is important for her to come to the party.=It is important that she(should)come to the party.19.It looks(seems)as if …
该句型中it 无意义。As if 引导一个状语从句，常译为：“看起来好像„„”如果与事实不相符合，则用虚拟语气。It looks as if he is ill.（真的病了）
It looks as if he was ill.（事实上没有生病）
20.We think it important to learn a foreign language.主句中的常用的动词：think, believe, make, find, consider, feel, take.We think it our duty to clean our classroom every day.Xiao Li felt it important learning English well.
第二篇：高中英语中六大从句用法总结
英语中六大从句用法总结
1.主语从句
1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有：
*It is a facta pitya questiongood news that...*It seemsappearshappenedhas turned out that...*It is clearimportantlikelypossible that...*It is saidreportedestimatedhas been proved that...It is said that comic books create a connection between people of the same generation.It seems that the performance is very useful.2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.I did know why I felt like crying.2.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.*All this is different from what American young people would say about friendship.*He is certain that watching so much television is not good for children.*This article is well-written except that it is a bit too long.2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.Perhaps the most important thing to remember is that there is no one common type of life in America.The reason why so many people died there is that there were not enough food supplies.It looks as if successful international cultural communication will make the world smaller.4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.I had no idea how many books I could borrow at a time.The news came that their team had won the championship.5.定语从句
定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句
限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.Those who live alone or who are sick may have trouble in getting close to other people.The girl whose parents died in an accident is living with her grandmother.1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。
That is all that I've heard from him.He's the first person that I'm going to interview this afternoon.2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
This is one of those things with which we have to put up.This is one of those things(whichthat)we have to put up with.3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which)there are no words,the stories are fully expressed through the drawings.No one knows the reason why(=for which)he was so angry that day.5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.*“介词+whichwhomwhose”引导的定语从句
“介词+whichwhomwhose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
6.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有：
1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.2)as soon as,hardly(scarcely)...when,no moment,immediately(that)等。
sooner...than,each(every)
time,the As soon as I sent an e-mail message,I received positive responses.The moment he heard the good news,he jumped with joy.*地点状语从句 引导地点状语从句的连词是where,wherever.Wherever she went,she took her little daughter with her.*原因、结果和目的状语从句
1）引导原因状语从句的从属连词有：because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.2)引导结果状语从句的连词有：so...that,such...that ,so that,that,so等。
Mickey Mouse is so attractive that the children are reluctant to leave.3)引导目的状语从句的连词有：so that,in order that,for fear that,lest等，从句常使用may,might,can,could,would等情态动词。
We got up early this morning so that we could catch the first bus to the railway station.*条件和让步状语从句
1）引导条件状语从句的连词和词组有if,unless,as(so)long as,on condition that,in case,provided(providing)that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。
No matter what you may say,I would not change my mind.Young as he is,he is quite experienced in this work.(=though he is young)Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。
The young man made the experiment just as the teacher had taught him.Everything went on as usual as if nothing had happened.
第三篇：英文中标点符号用法-小结
英语中的标点符号的用法
句号的用法
句号在英语中的使用频率仅次于逗号，通常用来表示一个句子的结束。常见的用法如下： 1)用于陈述句，以表示一个句子的结束，也可用于语气温和的祈使句或客气的问句之后。
2)用于某些缩略词之后。3)用作小数点
逗号的用法 分隔句首状语
常用于分隔用作独立成分状语等的下列词语。分隔日期、数学、地点。
分隔人名与职称头衔或倒置的姓名。分隔呼语
用于信件的称呼和浩特语之后或结束敬语之后。
分号的用法
分号是名副其实的分隔号，它不能用于完结一个句子，它通常用于并列的分句之间。一般来说，分号的作用介于句号与逗号之间，用分号隔开的两部分之间的关系，比用句号分开的紧密，但不及用逗号分开的紧密。分号一般有以下的用法：
1)用于并列分句之间，以分隔（通常）没有连词连接的主要从句，这些从句被认为是关系密切而属于一个句子。
2)用于for example, for instance, namely, that is(to say), in fact, i.e., e.g.等词语引出的分句之前。
冒号的用法
冒号是一个补充、连贯的符号，被用来引起读者注意下文。冒号多用于正式而庄重的问题中，具体用法如下：
1)列出表示列举、解释、或说明性的词语。2)引出较长的正式引语或大段引语。
3)用于信件或演说词中的称呼语之后（英国用法中多用逗号）。
4)用于时与分之间（英国用法中多用句号）、比率数之间、《圣经》的章与节之间。5)分隔书名的标题与副标题。
问号的用法
问号，就是用在问句之后的符号，多用于对话中，书面表达中相对较少。问号的一般用法如下：
1)用于疑问句或语气婉转的祈使句之后。2)用在括孤内表示存疑或无把握。
叹号的用法 感叹号，用于抒发强烈的情感，如惊叹，赞赏，呼吁，决心，或用来表示强调，命令等。通常感叹号有以下用法：
1)用于加强命令语气或引起注意。2)表示感叹、赞美、嘲讽或玩笑。
连字符的用法
在英语中，连字符的作用是多方面的，其用法灵活多变。通常连字符有下列用法： 1)用于复合词。
2)用于词缀（或组合语素）与词根（或词）之间。3)用以避免单词在语义或在语音上发生混淆或用于分离。4)用于两地名、两数字或两个时间之间，意为“至”。5)用于单词移行。
但移行时要注意以下几种情况：
※单间节词不能分开移行，例如strength 不宜分成steng-和th ※屈折变化形式不宜分开移行，例如working不宜分成work-和ing.※数字、缩略词不宜分开移行，例如25759和UNESCO 不宜分成257-和59，UNES-和CO。
※易引起岐义的词不宜分开移行，例如legend和earnest不宜分成leg-和end , ear-和nest 移行。
※移行后行尾不宜只剩一个字母，例如alike 和alone不宜分成a-和like，a-和lone.※有词缀的词应在词缀与词根处移处，例如unimportant 和disappear应在uni和important, dis-和appear
处分开移行。
※复合词应在复合成分之间移行（原有连字符号的，可在行尾用双连字号或在下一行行首加一连字号），注意：连字符不可与破折号相混，破折号起分隔句中的若干部分的作用，连字符的长度为破折号的一半。
破折号的用法
破折号是用来加强语气的符号，表示意思突然转折，往往起到冒号，分号或逗号的作用。其用法如下：
1)表示话语突然中断、意思突然转折或犹豫不决。2)引出被强调的词语。
3)分隔非限定性修饰语、同位语或附加成分的词语。4)引出概括性词语。5)表示引文出处。
6)用于两地名或两个时间之间，意为“至”，引号的用法
引号有双引号和单引号之分，事实上，双引号较单引号常用，单引号多见于报刊的新闻标题中。引号有下列几种用法： 1)用于直接引语。注意句子中其他标点符号与引号的相对位置：
逗号、句号位于引号内（这是美国用法，英国用法多置于引号外），在引语内再用引语时，可用单引号（这是美国用法，在英国用法中，单引号在外，双引号在内）。引语不止一段时，引号位于各段起始处和最后一段结尾处。
2)用于引述文章、文艺作品、歌曲、广播及电视节目、绘画等。
撇号的用法
撇号主要有以下用法：
1)表示名词或不定代词的所有格。构成规则：
不以s结尾单复数名词加's，如John's bike 约翰的自行车 以s结尾的单复数名词加'，如student' room 学生房间
以s结尾的单数名语加's或' , 如Charles' brother / Charles's brother 查尔斯的弟弟 2)表示数学、符号、字母或词形本身的复数。3)表示省略了字母、数字或单词。
圆括号的用法
圆括号主要用于句子内容的补充说明。其功能相当于英语的插入语，具体用法如下： 1)括出例证、引文出处、参见、补充说明等解释性文字。2)括出表示列举的数字或字母。3)括出可省略的词语。
4)括出注释中刊物的出版地、出版商及出版年代等内容，5)括出可供选择的内容
方括号的用法
方括号通常是写作中用来表达意见，评论，或用于进行内容更正的专用符号。其用法如下： 1)引述他人文字中插入自己解释性或评述性的词语。2)对原文加以修正。3)括出剧本中的舞台提示。4)作圆括号内的括号。
删节号的用法
删节号又称省略号，通常用来表示引文中的省略部分或话语中未能说完的部分，也可表示话语中断断续续的停顿。星号（Asterisk）有时也用来表示省略，但此用法在现代英语中已渐渐消失，删节号的用法为： 1)表示词语省略
2)表示语句中的断续、停顿、犹豫。3)表示整行诗文的省略
斜线号的用法
斜线号的主要功能是分隔作用，其具体用法有： 1)用于分隔替换词。/or students.可以是老师和/或学生。2)用于分隔并列词语。3)用于某些缩略词中。4)用于速度、度量衡等单位中。5)用于某些数字组合中 6)用于诗歌分行。

It用法小结
it在英语语法中属人称代词，意思是“它”，用来指人以外的一切生物和事物。它的用法不仅不简单，而且很复杂。
一、用于指人以外的一切生物、无生命的东西和事情。
一般指说话者心目中已经了解或所指的生物、无生命的东西或事情、没有性别的区分；可以是可数名词，也可以是不可数名词，在句子中既可做主语，也可以作宾语。
1．指动物和植物。如：
—Oh，that's Lucy's hat．噢，那是露茜的帽子。
—It looks like a cat！它看上去像只猫！
Where's tea grown？It's grown in the southeast of China．
什么地方种植茶？中国东南部种植茶。
2．指代一些无生命的东西。如：
Is it your watch？这是你的手表吗？
Look at the rain！It's heavy，isn't it？看这雨！雨很大，对吗？
3．代替上文提到过的整个事情。如：
Well，you mustn't play on the road．It's dangerous．哦，你不能在公路上玩。这太危险了！It was hard work，but they really enjoyed it．摘苹果是艰苦活，可他们都乐意去干（它）。
二、用于指代人。
1．指代说话者心目中不太清楚的那个人，常在打电话或敲门时用。如：
—Who was it？是谁（打来的电话）？
—Was it Susan？（打电话的）是苏珊吗？
—Yes，it was．是的，我是。（根据上下句，“it was”也可不译出来。）
再如：—Who is knocking at the door？谁在敲门？
—It's me．是我。
2．指说话者心目中的那个人。如：
—Is it your sister，Kate？（那旧照片上的 baby）是你姐姐凯特吧？
—No！不是。
—Is it your brother？是你哥哥吧？
—No！不是。
—I know—it's you！我知道了，（那）是你。
3．指代性别不详的婴幼儿或在不计较性别时，也可用it来指人。如
The child smiled when it saw its mother．这小孩一见到母亲就笑了。
I don't know who it is．我不知道他是谁。
注意：看到这样的句子（或听到这样的话）时，要想一想，不要一看到it就把它译成“它”。）
4．在回答用指示代词表示人的特殊问句时，常用it指人。如：
—Who's that？那人是谁？
—Is it Kate？是凯特吗？
—Yes，I think you're right．It's Kate．是的，我想你说对了，是凯特。
三、用于指时间、距离和自然现象等。
1．表示时间。如：
—What time is it？几点钟？
—It's ten．十点钟。
It's summer in Australia now．现在澳大利亚是夏天。
特别注意it用于表示时间时还常见于以下两个句型中：
（1）It's time（for sb．）to do sth．／It's time for sth．译为“是（某人）该干„„的时间了”、“到„„的时候了”。如：
It's time for supper／to have supper．是吃晚饭的时候了。
I think it's time for us to start the lesson now．我想现在是我们开始上课的时候了。
（2）It is ／has been ＋时间段＋since ＋一般过去时。译为“自从„„以来已过了„„（时间）”。此结构可以与另一种句型进行同义句转换。如：
It has been two weeks since we met last．＝ Two weeks has passed since we met last．自从我们上次相遇以来，两个星期过去了。
It's three years since he came here．＝It has been three years since he came here．＝He has been here for three years．他到这里已经三年了。
2．表示距离。如：
It's half an hour's walk from my home to the school．从我家到学校步行得花半小时时间。—Where's the farm，Li Lei？Is it far？李雷，农场在哪里？远吗？
—No，it's quite near．不，（距）离这很近。
3．表示自然现象。如：
Sometimes it snows and the land is all white．有时下雪，大地一片白。
It is very quiet here at the moment．眼下这儿很安静。
四、用作形式主语。
英语中常常见到某个句子以it开头，it与其后面的动词不定式短语、动名词短语、名词性从句等相呼应，以表达一个完整的意义。这是一种习惯表达法，这样的句式可避免句子显得头重脚轻。
1．It＋is／was＋形容词＋（for／of sb．）＋动词不定式短语。对于这个句型中究竟用 for还是用of，一般遵循这样的规则：如果形容词仅仅是描述事物的形容词，如：difficult，easy，hard，important，dangerous等用for；如果形容词是描述不定式行为者的性格、品质的，如：kind，good，nice，clever等则用of。如：
It is interesting to play with snow in winter．冬季里玩雪是很有趣的。
It's important for us to keep the water clean．保持水质清洁对我们来说是很重要的。It's very kind of you to say so．你这样说真是太好了。
注意：这一句式中的形容词位置也可换用名词；连系动词be也可换用其它连系动词，如feel等。如：
It's a good habit to get up early and go to bed early．早睡早起是好习惯。
It must be great fun to fly to the moon in a spaceship．乘宇宙飞船飞往月球一定很有趣。It feels strange to have a twin sister．有个孪生姐妹感觉很奇怪。
2．It ＋will be／is ／was ＋形容词＋动名词短语。如：
It's bad playing in the street．在街上玩是没好处的。
Is it any good trying again？再试一次有用吗？
3．It＋is／was＋形容词＋从句。如：
It is certain that he will come．他一定会来。
It's true that he may fall behind the other students．他真的可能落后于其他同学。
It is strange that he should say so．他居然这么说，真是奇怪。
4．It ＋is ／was ＋one's turn（duty，pleasure）＋to do sth．意为“该轮到某人做某事（做某事是某人的责任、愉悦的事）”。如：
It's your turn to be on duty tomorrow．明天轮到你值日了。
5．It takes（sb．）some time to do sth．意为“（某人）花„„时间做某事”。如
It took me a week to finish reading the book．我花了一周时间看完这本书。
6．It ＋cost／costs ＋sb．＋some money ＋to do sth．译为“某人花多少钱做某事”。如：It cost me 260 yuan to buy the new watch．我买这块新手表花了260元。
7．It seems ／seemed ＋从句。译为“看起来好像„„”，此结构可以转换成“seem ＋动词不定式”形式。如：
It seems that he is ill．＝He seems to be ill．看起来他好像病了。

② In fact________ is a hard job for the police to keep order in an important football match.A.thisB.thatC.thereD.it
答案: ① D ② D
五、用作形式宾语。
当句子的真正宾语是动词不定式、动名词或从句时，为避免句子头重脚轻，须将其放在宾语补足语之后，改用先行词it占据其原来的位置。it用作形式宾语的句型为：主语＋谓语＋it＋宾语补足语＋动词不定式／动名词／从句。该句型中宾语补足语可由形容词、名词等充当。如：
He found it not easy to learn a foreign language well．他发现学好一门外语是不容易的。We think it no good reading in bed．我们认为躺在床上看书无益处。
I think it necessary that we have the meeting．我认为开这个会是必要的。
