高中英语语法高考二轮复习it考点讲义【精讲版】it用作形式主语和形式宾语的用法归纳总结一、用作形式主语当不定式、动名词、从句等用作主语时,避免头重脚轻,通常在句首使用形式主语厄而把真正的主语放在句子末尾。

如:It is stupid to do such a thing.做这种事真蠢。

It's no good sitting up too late.熬夜没有好处。

It is necessary that he should be sent there at once.有必要马上派他到那里去。

注:类似以下句子中的il也可视为形式主语:It happened that the harvest was bad in 1988.碰巧1988 年的收成很不好。

It seems that she is afraid to tell them about it.似乎她怕将此事告诉他们。

二、用作形式宾语当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时,就应在宾语补足语前使用形式宾语,而将真正的宾语移至句末。

如:I've made it a rule never to hurry,我已养成凡事从容不迫的习惯。

Do you think it possible to root out crime?你认为可以根除犯罪吗?He found il difficult to breathe at high altitudes.他觉得在高空呼吸困难。

注:通常意义的形式宾语主要见于真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形,即用于“动词+it+宾语补足语+真正的宾语”这样的结构,但以下两类形式宾语却比较特殊,其后没有宾语补足语:1.由于介词后通常不能直接跟that从句作宾语,有个别特殊结构就在介词后先接it作形式宾语,再跟that从句。

如:You may depend on it that it is true.你可以相信这是真的。

高中英语知识点归纳形式主语和真正主语的用法区别

高中英语知识点归纳形式主语和真正主语的用法区别

高中英语知识点归纳形式主语和真正主语的用法区别形式主语和真正主语在句子中起着不同的作用,它们的使用方法也存在一些区别。

了解形式主语和真正主语的用法区别,可以帮助我们更好地理解和运用英语语法。

本文将详细介绍这两种主语的区别及其使用方法。

一、形式主语的定义和用法形式主语是英语句子中的一个特殊结构,一般由"it"作为形式主语,而真正的主语通常位于句子后面。

用形式主语可以使句子结构更为简洁,突出真正的主语或具体的动作。

下面是几个形式主语的典型应用场景:1. 天气描述:It is raining. (下雨了。

)形式主语"it"用于表示天气状况,并将真正主语"raining"后置。

2. 环境描述:It is sunny today. (今天阳光明媚。

)形式主语"it"用于描述一种环境状态,真正主语"today"被放在句末。

3. 存在句:It is a lovely cat. (这是一只可爱的猫。

)形式主语"it"用于指代前面的主语"a lovely cat",以使句子结构更加自然。

4. 距离表达:It is two miles away. (距离这里有两英里。

)形式主语"it"用于介词短语中表示距离,真正主语"two miles"位于动词"be"之后。

二、真正主语的定义和用法真正主语指的是句子中进行动作或存在的对象,它在句子中的位置往往较为灵活,可以位于句首、句中或句末。

下面是几个真正主语的常见用法:1. 人称主语:Tom is a student. (汤姆是一个学生。

)真正主语"Tom"作为人的称谓,出现在句首,是一个常见的用法。

2. 名词短语主语:My sister likes to read books. (我的妹妹喜欢读书。

高中英语语法--主语从句复习

主语从句1)主语从句定义:在句子中担当主语的是一个从句,这个从句就叫做主语从句。

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。

主语从句主要有三类:(1)由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。

例如:That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。

That you are so indifferent bothers me.你如此冷淡使我很烦恼。

That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。

(2)用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。

例如:Whether she is coming or not doesn’t matter too much.她来不来都无关紧要。

(3)用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomev er, whichever, whatever引导的名词性从句中,其连接代词在句中起名词性作用,担当一定成分).例如:What you need is more practice.你所需要的是更多的训练。

What I want to know is this. 我想知道的就是这事。

Whatever we do is to serve the people.我们无论做什么都是为人民服务。

(4)用连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。

)eg:Where we should leave it is a problem.When they will come hasn’t been made pubic.他们什么时候来还不知道。

高中英语语法:It的用法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18)It is difficult to translate this article. 翻译这篇文章很难。

19)It is getting harder every day for a lazy man to get a living. 懒汉谋生是日益困难了。

23)It is strange that he did not come at all. 真奇怪,他竟还没来。

24)It doesn't matter what you do.什么都没关系。

在上述诸例中,后置的真正主语可以取代先行it的位置,而出现于句首。

To translate this article is difficult.Going there so early is no use.That he did not come at all is strange.上述结构远不如用先行it结构普通。

此外,也并非所有先行it结构都可作上述转换。

如:25)It seems that John is not coming after all. 似乎约翰终竟不来。

26)It happened that John was the only witness. 碰巧约翰是唯一的证人。

28)He thought it no use going over the subject again. 他认为再讨论这个问题没有用了。

5. 分裂句引导词it.分裂句是以it为引导词的强调句型。

它的结构形式是:It+be的一定形式+中心成分+that-/who-从句。

如:31)It was Jane that/who called this morning. 是珍妮今天上午打来电话。

32)It was a parcel that she brought him. 她带给他的是一个包裹。

分裂句是由普通陈述句转换而来的。

通过这种结构可以强调除谓语动词以外的大多数句子成分。

如:33)John gave Mary a handbag at Christmas. 约翰在圣诞节给了玛丽一个提包。

根据上下文和语义意图,说话人可以通过分裂句分别强调主语、间接宾语、直接宾语、状语,使之成为信息中心。

34)It was John that/who gave Mary a handbag at Christmas. 是约翰在圣诞节给了玛丽一个提包。

35)It was Mary that John gave a handbag (to)at Christmas. 约翰在圣诞节是给玛丽提包的。

36)It was a handbag that John gave Mary at Christmas. 约翰在圣诞节给玛丽的是一个提包。

37)It was at Christmas that John gave Mary a handbag. 是在圣诞节约翰给了玛丽一个提包。

分裂句的时态一般应一致,即主句与从句的时态应皆用现在时,或皆用过去时,或皆用将来时。

如:38)It is not I who am angry. 发怒的不是我。

39)It was my two sisters who knew her best. 是我的两个姐妹最了解她。

40)It will not be you who will have to take the blame for this. 对此须受责难的将不是你。

有时分裂句的谓语动词还可以采取复杂形式。

如:41)It may have been at Christmas that John gave Mary a handbag. 可能是在圣诞节约翰给玛丽一个提包。

42)It might have been John who gave Mary a handbag. 很可能是约翰给了玛丽一个提包。

分裂句可以强调多种多样的状语成分。

如:43)It was when she was about to go to bed that the telephone rang. 是在她即将上床睡觉时电话铃响了。

44)It was because I wanted to buy a dictionary that I went to town yesterday. 我昨天是由于想买一本词典而进城的。

45)It was not until his father came back that Tom went to bed yesterday.昨天汤姆是直到他父亲回来才上床睡觉的。

(注意句中not的位置)主语补语通常不可以用作分裂句的中心成分,如在规范英语中通常不说:It is beautiful that she is.It is chairman of the Committee that he is.但是宾语补语是可以这样用的。

如:46)It is the chairman of the committee that they elected him. 他们选他是作委员会主席。

47)It is green that they have painted the wall. 他们把墙壁漆的是绿色。

注:(1)当强调的中心成分为主语,指人时可用连词that或who,如上述例(31)、(34)、(38),强调其余的成分时,连词一律用that。

(2)分裂句中的that与who在非正式文体中可以省略,如:48)It was the President himself spoke to me.是总统亲自和我谈了话。

(省去从句主语who)49)It was the dog I gave the water to. 我是给那条狗水的。

(省去从句的宾语that)50)It was yesterday I first noticed it. 我是昨天开始注意到的。

(省去从句连词that)有时还可省去句首的it is,如:51)A good, honest trade you are learning, Sir Peter! 彼得爵士,你学得是一种很好而诚实的一行啊!(3)分裂句中的被强调部分有时可放在句首,如:52)Now was it that his life was done, and the fate which he could not escape was upon him.就在这时,他的生命完结了,他所逃不脱的命运降临了。
