it在句子中的用法总结

it在句子中的用法总结

it在句子中的用法总结一、IT在句子中的基本用法IT是英语中一个常见的代词,表示“它”。

在句子中,IT有以下几种基本用法。

1. 作为主语:当句子的主语是不具体或未知的时候,可以使用IT作为占位符。

例如:“It is raining.”(下雨了)这个句子中,主语是下雨这个动作,并没有具体的人或物承担该动作。

2. 作为形式主语:有些动词需要跟形式主语it连用,而真正的主语放在后面的从句中。

例如:“It is important to learn a second language.”(学习第二门语言很重要)这个句子中,“to learn a second language”是真正的主语,而it充当形式主语引导句子。

3. 作为强调结构:在强调特定信息时,可以使用“It is…”结构。

例如:“It was John who broke the window.”(是约翰打碎了窗户)这个句子中,通过加强重要信息“John”来引起对他行为的关注。

二、IT在不同情况下的具体应用1. 时间和天气描述:IT经常用于描述时间和天气条件。

例如:“What time is it?”(现在几点了?)和“It's hot today.”(今天很热)。

在这种情况下,IT没有特定的指代,只是用于描述一个普遍的信息。

2. 物体或事物说明:IT也用于指代不具体的事物或对象。

例如:“I can't findmy book. Have you seen it?”(我找不到我的书了,你看见它了吗?)在这个句子中,it用来代替已知的书。

3. 引入后面的从句:在想要引入一个补充信息或解释时,一般使用It +that/whether/if来引导从句。

例如:“It is not clear whether he will come or not.”(他是否会来还不清楚)。

在这个句子中,“whether he will come or not”是由it引导的从句。

英语中it的用法

英语中it的用法

it 在英语中的意思较多,用法较广,现总结如下;一、it作句子的真正主语1.it 指前面已经提到过的人或事物,有时指心目中的或成为问题的人或事物,作真正主语;例如:What’s this -It is a sheep这是什么这是一只绵羊;Who is it -It’s me I. 谁是我;It’s the wind shaking the window. 是风刮得窗户响;2.it指时间、季节;一般用在无人称动词的主语;例如:What time is it -It’s nine. 几点了九点了;It’s time for the meeting. Let’s go. 开会的时间到了,我们走吧;What day is today -It’s Saturday. 今天星期几今天星期六;What’s the date today -It is October 1st.今天是几号今天是十月一日;What season is it -It is summer. 现在是什么季节是夏季;3.it 指气候;一般作无人称动词的主语;例如:Is it cold in this room -No, it isn’t. 屋里冷吗不冷;What’s the weather like today -It is fine.今天天气怎么样是晴天;It often rains in summer and it often snows in winter in this city.这个城市夏天经常下雨,冬天经常下雪;4.it指距离、情况等;一般用作无人称动词的主语;例如:It is five kilometers from my home to the school.从我家到学校有五公里;It is very near from this factory to that one.从这个工厂到那个工厂非常近;It is a long way to the sea. 离海很远;Is it well with you 你身体好吗二、it作形式主语动词不定式、动名词短语起、从句在句子中起主语作用,而这一部分用词较多时,可以用it作为形式主语,放在句首代表其后所说的事实上的、真正的主语,而把真正的主语放在后面;1.It +谓语+动词不定式;It 作形式主语,动词不定式作真正的主语;例如:It is difficult to climb a mountain. 爬山是很艰难的;It’s a good habit to do morning exercises. 作早操是个好习惯;It’s important to do proper memory work in the study of a foreign language. 在学习外语时适当地做一些有助于记忆的练习是很重要的;It is right to do so. 这样做是对的;2.It+谓语+动名词短语;It 作形式主语,动名词短语作真正的主语;例如:It is dangerous playing with fire. 玩火是危险的;It is no use learning without thinking. 学而不思则罔;It’s useless arguing with a silly boy. 和笨孩子争论是没有用的;3.It +谓语+名词性从句;It 作形式主语,以that 引导的名词性从句是真正的主语;例如:It is a pity that you didn’t see such a good film.你没看这么好的电影,真可惜;It is certain that we shall succeed. 我们一定会成功;It is strange that nobody knows where he lives.真奇怪,谁也不知道他住在哪里;It is strange that…后面可用虚拟语气;如:It is strange that he should have made such a mistake.他居然犯了这样一个错误,真奇怪;It is strange that nobody should know where he lives.居然没有人知道他住在哪里,真奇怪;It is said that the plane will take off at ten tomorrow morning.据说飞机明天上午十点起飞;三、it作形式宾语it 作形式宾语,代表其后所说的真正的宾语;真正的宾语是以that 引导的名词性从句或不定式短语;例如:I consider it wrong that you Chinese students learn English without comparing it with your own language.我认为你们中国学生学习英语,不和你们自己的语言比较是不对的;I find it not so difficult to learn a foreign language.我发现学习一门外语不那么困难;I remember I made it clear to you that I was not coming.我记得向你明确表示过我不来;They want to make it clear to the public that they are doing an important and necessary job.他们要向公众表明,他们在做一件重要而又必要的工作;四、it 用于强调结构在表示强调的结构中,it 可用作先行代词,这种结构的句型如下:It +is/was +被强调的部分+that +其他部分;如果强调的部分是人,可用who, whom 代替that.例如:Professor Wang teaches us English every Monday afternoon.王教授每星期一下午教我们英语;强调主语:It is Professor Wang who teaches us English every Monday afternoon.强调间接宾语:It is us whom Prof. Wang teaches English every Monday afternoon. 强调直接宾语:It is English that Prof. Wang teaches us every Monday afternoon.强调状语:It is every Monday afternoon that Prof. Wang teaches us English.It was here that I first met him. 这就是我初次与他见面的地方;强调状语It is the people who are realy powerful.翻译练习1该上课了,快;It is time for class. Hurry up.2从这儿到你们学校远吗不远,大约一公里;Is it far from here to your school No, it isn’t. It’s about a kilometer.3从我家到颐和园去很近;It is very near from my home to the Summer Palace.4天正在下雨;It’s raining now.5电灯是爱迪生发明的;It was Edison who invented the electric light.6我认为学习一门外语是很重要的;I think it important to learn a foreign language.7他通常一天读两次英语;He made it a rule to read English twice a day.8从我家去天安门广场坐公共汽车大约要一个小时;It takes about an hour to go from my home to the Tian’anmen Square by bus.反意疑问句反意疑问句相当于“对不对”“好不好”“行不行”,用yes或 no 回答;由两部分组成,前一部分是陈述句,后一部分是附加疑问短语,中间用逗号隔开,所以反意疑问句又叫附加疑问句;通常的形式是:肯定的陈述句+否定的附加疑问,或否定的陈述句+肯定的附加疑问;如:He studies English, doesn’t heHe doesn’t study English, does heThey are from America, aren’t theyThey are not from America, are they反意疑问句的主要形式:1.如果主句是be或其他助动词如can, shall, will 等,其反意疑问句用同一助动词; 如:We are late, aren’t weYou haven’t met my wife, have youHe can drive a car, can’t heThey used to have difficulty in just making ends meet, didn’t usedn’t theyYou’d better eat with knives and forks, hadn’t you2.如果主语带有seldom, hardly, never, rarely, few, little等否定词或半否定词时,因为主句本身具有否定意义,附加疑问部分的动词用肯定式,如:We seldom go to the cinema, do weSue almost never worked, did she3.如果主句部分是“I am…”结构,由于”am not” 没有相应的缩略形式,附加疑问部分一般用aren’t I 代替;如:I am your friend, aren’t II’m late, aren’t II am a student, aren’t I在祈使句中的附加疑问部分一般用will you, won’t you.4. 在祈使句中的附加疑问部分一般用will you, won’t you.如:Sit down, will youHave some tea, won’t youOpen the window, won’t you这种句子可以理解为: Will you do something如:Will you open the window注意:否定的祈使句之后,只能用will.Don’t forget, will youDon’t make so much noise, will you5.以Let’s… 开头的祈使句,肯定的用shall we否定的用all right或OK,如:Let’s go back to our seats, shall weLet’s not have hot food this t ime, OK all right这种句子可以理解为:Shall we do something,如:Shall we go back to our seats.这样有助于理解和记忆;注意:Let’s 与Let us 的区别:Let’s包括听话人在内,应用shall we, 而Let us 不包括听话人在内,表示“请你让我们…”,要用will you.如:Let’s watch the news on TV, shall we 表示建议Let us watch the news on TV, will you 表示请求6.主句是I suppose, I think, I believe等时,附加疑问部分则往往与that 从句中的主语和谓语动词保持对应关系,但要注意否定的转移;如:I suppose that you know the meaning of the word, don’t you这句话明显是要问“你是不是知道”而不是问“我是不是这样认为”I don’t think that you have read the book, have you7.当主句的动词have 表示“拥有”时,附加疑问既可用have, 也可用do,如:You have a color TV set, haven’t you/don’t you当主句的have不表示“拥有”而表示其他意思时,附加疑问要用do,如:You had a cold yesterday, didn’t youThey don’t have coffee with breakfast, do theybe句型的反意疑问句,用there 作主语;如:There is something wrong, isn’t thereThere won’t be any trouble, will there 不会有任何麻烦,是吗9.陈述部分的主语是everyone, someone, anyone, no one, nobody等不定代词时,其疑问部分的主语可用he, 也可用they.Everyone knows it, doesn’t he/don’t they英语反意疑问句的回答有点和汉语的相反;但一定要记住:只要回答是肯定的,都用yes,只要回答是否定的,都用no;这在主句是否定句的时候要特别注意;例如:Mr. Jones can’t speak French, can he No, he can’t.琼斯先生不会讲法语,对吗对,他不会讲法语;Mr. Jones can’t speak French, can he Yes, he can.琼斯先生不会讲法语,对吗不,他会讲法语;This is not a door, is it -Yes, it is. It is an iron door.这不是门,对吗不,这是门;是扇铁门;。
