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
英语中代词的用法 代词是代替名词的一种词类。大多数代词具有名词和形容词的功能。英语中的代词，按其意义、特征及在句中的作用分为：人称代词、物主代词、指示代词、自身代词、相互代词、疑问代词、关系代词和不定代词八种。 一、人称代词是表示"我"、"你"、"他"、"她"、"它"、"我们"、"你们"、"他们"的词。人称代词有人称、数和格的变化，见下表： 数单数复数 格主格宾格主格宾格 第一人称I me we us 第二人称you you you you he him they them 第三人称she her hey them it it t they them 主格作主语或表语，如：He is my friend. 他是我的朋友。It’s me. 是我。 宾格作及物动词和介词的宾语, 还可作表语. Aunt Li took care of us. Who is knocking at the door It's me. 二、物主代词表示所有关系的代词，也可叫做代词所有格。物主代词分形容性物主代词和名词性物主代词二种，其人物和数的变化见下表。 形容词性物主代词my your his/her its our your their 名词性物主代词mine yours his/hers its ours yours/ theirs 形容词性物主代词只能做定语,修饰名词,相当于形容词,如：I like his car. 我喜欢他的小汽车。 名词性物主代词可以做主语、宾语和表语，相当于名词, 如：Our school is here，and theirs is there. 我们的学校在这儿，他们的在那儿。 三、指示代词表示"那个"、"这个"、"这些"、"那些"等指示概念的代词。指示代词有this，that，these，those 等。 如：That is a good idea. 那是个好主意。 四、表示"我自己"、"你自己"、"他自己"、"我们自己"、"你们自己"和"他们自己"等的代词，叫做自身代词，也称为"反身代词"。反身代词表示主语发生的动作落在主语自己身上,或用来加强名词或代词的语气。 如：She was talking to herself. 她自言自语。 I hope he didn't hurt herself. She taught herself English. 五、表示相互关系的代词叫相互代词，有each other和one another两组，但在运用中，这两组词没什么区别。 如：They love each other. 他们彼此相爱。 六、不是指明代替任何特定名词的代词叫做不定代词。常见的不定代词有a11，both，each，every等，以及含有some-，any-，no-等的合成代词，如anybody，something，none。这些不定代词大都可以代替名词和形容词，在句中作主语、宾语、表语和定语，但none和由some，any，no等构成的复合不定代词只能作主语、宾语或表语；every和no只能作定语。如： ---Do you have a car? --你有一辆小汽车吗？ ---Yes，I have one. --是的，我有一辆。

代词one,it,that的用法区别 代词one, it that的用法在历届高考题中出现的频率较高，是高考的热点之一。 1）one, it, that常常用来代替或避免重复某个名词。例如： ①I'm looking for a flat. I'd really like one with a garden. ②-Where did you find your watch? - I find it in our classroom. ③The population of China is larger than that of any other country. 2）one可指人或物，只替代单数可数名词，复数用ones. One是泛指，但有限定修饰语，如the, this, that…修饰就变成了特指。如： ①One must do one's duty. ②Mary has a red pencil and Jane has a blue one. ③The new designs are much better than the old ones. 3）.that只指物，不指人，可替代可数名词或不可数名词，具有“特指”性质。指的是同类事物中的另一样东西，即同类异物。如：The library of our school is bigger than that of yours.(that 代替的是另一个图书馆。) 4）one 和that 在代替可数名词时，如果没有前置定语只有后置定语时，the one 和that 可互换。但该名词如有前置定语，则只能用the one,而不能用that。例如： ①I will take the seat next to the one(=that)by the window.我就坐窗口的那个座位旁边。 ②I prefer the large box to the small one.(one 不可用that替换)。 5）That的复数形式those代替可数名词的复数。可指人或物，一般后面跟修饰语。如： ①Today's cellphones are smaller than those(=the ones)used in the past. ②The students who do best in exam are not always those(=the ones) with the best brains. 6）the one(ones)或that ,those 指代某一名词做定语从句的先行词时，其关系代词which在that之后，which不能省略，而在the one、ones 之后,which可省略。如： ①Their problem today is somewhat similar to that which they faced many years ago. 7）代替不可数名词时，应该用that。如：The equipment is different from that. 8）it代替上文所提到的名词时，是指同类事物中的同一样东西，即同类事物。如： I have lost my pen. I'm looking for it. 9）it和that可代替前面整个句子的意思，而one却不能；that可引导一个限定性定语从句，代替某个先行词（单复数名词均可），it和one则不能；it可代替不定式、动名词或从句，用作形式主语或形式宾语，也可用于强调句型中，而one和that则不能。如： ①-I will make bed for you. –It is very kind of you. ②Jim said he had read my novel.But that was not possible. ③A clock is an instrument that tells time. ④The students that surf the Internet will be punished by the teacher. ⑤It is nice to see you again. ⑥It is no use calling her up. ⑦I found it impossible for me to pass the test. ⑧It was I who broke your window.

【英语】英语代词用法总结(完整) 一、单项选择代词 1．-Which of these two ties will you take? -I don't like these. Do you have any_____? A．one B．other C．ones D．others 【答案】D 【解析】 考查对不定代词的用法。--两个领带你想要哪一个？--都不喜欢，还有其他的吗？ others=other+名词”，泛指“别的人或物，其他的人/物”，故选D。 【名师点睛】不定代词one，ones ， other 和others的区别。 不定代词即不指明代替任何特定名词或形容词的代词。 1.不定代词one指代可数名词，既可指人，亦可指物，它可以代替上文中出现的单数可数名词，指代复数名词时可以用ones。 例如：I do not have a pen, can you lend me one? I like small cars better than large ones. 2.other具有名词和形容词性质，既可指人，亦可指物。other常与定冠词the连用。other只作形容词或代词，表示“其他的，别的”，不可单独使用。 例如：Do you have any other questions? the other作形容词或代词，特指两者中或两部分的另一个或另一部分。 3.others相当于“other+名词”，泛指“别的人或物”，只有名词性用法。 例如：Some are planting trees, others are watering them. 2．You should make ______ a rule to leave things______ you can find them easily. A．it; where B．it; then C．that; there D．this; when 【答案】A 【解析】 考查代词及状语从句。句中it作形式宾语，真正宾语为to leave things where you can find them easily；where引导地点状语从句，选A。 3．-Which of the ways should I take to the village? - way as you please．All seem to be equal in distance． A．Neither B．None C．Any D．Either 【答案】C 【解析】 考查代词：A．Neither两者都不，B．None三者以上都不，C．Any三者任何一个，D．Either两者任何一个，从后面的all看出路是三条以上，句意是：--你想走哪条路去村子？-你喜欢走哪条就走哪条，距离上都是一样的。选C。
it作形式主语和形式宾语 it既可作人称代词，用来表示动物或无生命的物体等，也可以作无人称代词，在句中作主语，表示“时间”、“距离”、“天气”等。它还可以引导强调句，使语气得以加强。此外，it在句中能作引导词，充当句子中的形式上的成分，如形式主语、形式宾语等。 ㈠it作形式主语：it作形式主语时没有具体的意义，而只是帮助把真正的主语移到句子后部去，使句子显得平稳一些。it作形式主语时，可以代替三种形式：不定式、动名词和主语从句。 1. it代替不定式短语常用于下列句型中： It + be +形容词+ (for/of sb.) to do sth. It + be + 名词+ to do sth. It takes sb. some time to do sth. 干…花了某人…时间 It’s up to sb. to do sth. 干…是某人的职责或义务 如：①It is everyone’s duty to obey the law.遵守法律是每个人的义务。 （it作形式主语, 代替不定式短语to obey the law） ②It is difficult for a foreigner to learn Chinese.对于一个外国人来说，学习汉语是困难的。 （it作形式主语, 代替不定式短语to learn Chinese） ③It is not right to use these places as rubbish dumps.把这些地方用来倒垃圾是不对的。 （it作形式主语, 代替不定式短语to use these places as rubbish dumps） ④It took them a year to build the bridge.建这座桥花了他们一年的时间。 （it作形式主语, 代替不定式短语to build the bridge） ⑤It is bad manners to stare at people.瞪着眼睛看人是不礼貌的。 （it作形式主语, 代替不定式短语to stare at people） ⑥It is up to us to help those in need.帮助那些有困难的人是我们的责任。 （it作形式主语, 代替不定式短语to help those in need） ⑦It is not up to you to tell me how to do my job.我怎样干我的工作不用你来多嘴。 （it作形式主语, 代替不定式短语to tell me how to do my job） ◆ It be + 形容词+ for sb. to do sth.与It be + 形容词+of sb. to do sth.： 如果句型中的形容词描述的是sb.的品质、品格，在逻辑上可以作sb.的表语，则sb.前应用介词of，否则就用for。如：①It’s n ecessary for us to use a short-wave radio to pick up the programmes.我们用一台短波收音机收听这些节目是必要的。

英语语法：代词的用法 代词是代替名词的词类。大多数代词具有名词和形容词的功能。英语中的代词，按其意义、特征及在句中的作用分为：人称代词、物主代词、指示代词、自身代词、相互代词、疑问代词、关系代词和不定代词八种。下面就来跟着小编一起学习英语语法：代词的用法吧。 英语语法：代词的用法 一、人称代词是表示我、你、他、她、它、我们、你们、他们的词。人称代词有人称、数和格的变化，见下表： 数 单数 复数 格 主格 宾格 主格 宾格 第一人称 I me we us
第二人称 you you you you 第三人称 he him they them she her they them it it they them 例如：Heis my friend. 他是我的朋友。 Its me. 是我。 二、物主代词是表示所有关系的代词，也可叫做代词所有格。物主代词分形容性物主代词和名词性物主代词两种，其人物和数的变
化见下表。 数 单数 复数 人称 第一人称 第二人称 第三人称 第一人称 第二人称 第三人称 形容词性物主代词my your his/her/its our your their 名词性物主代词mine yours his/hers/its
ours yours theirs 例如：I like his car. 我喜欢他的小汽车。 Our school is here，and theirs is there. 我们的学校在这儿，他们的在那儿。 三、指示代词表示那个、这个、这些、那些等指示概念的代词。指示代词有this，that，these，those等。例如： That is a good idea. 那是个好主意。 四、表示我自己、你自己、他自己、我们自己、你们自己和他们自己等的代词，叫做自身代词，也称为反身代词。 例如：She was talking to herself. 她自言自语。 五、表示相互关系的代词叫相互代词，有each other 和one another两组，但在运用中，这两组词没什么大的区别。(有语法专家认为each other 指两者，one another表示三者及以上的彼此。) 例如：They love each other. 他们彼此相爱。 六、不是指明代替任何特定名词的代词叫做不定代词。常见的不定代词有a11，both，each，every等，以及含有some-，any-，no-等的合成代词，如anybody，something，no one。这些不定代词大都可以代替名词和形容词，在句中作主语、宾语、表语和定语，但none和由some，any，no等构成的复合不定代词只能作主语、宾语或表语;every和no只能作定语。例如：
代词及It用法 代词是代替名词的词，英语中代词有人称代词、物主代词、反身代词、相互代词、指示代词、不定代词、疑问代词、连接代词和关系代词等九种。 一、人称代词： (一)概述 表示“我(们)”、“你(们)”、“他/她/它(们)”等的词叫人称代词，它有人称、数和格的变化，其形式列 (二)人称代词的句法功能： 人称代词在句中的功能是通过“格”表现出来的，不同的格表明人称代词在句中有不同的句法功能。如： 1、主格形式作主语和表语。 He was late yesterday.昨天他迟到了。 They went to the cinema together.他们一起去看电影去了。 She and I are very good friends.我和她是很要好的朋友。 ---Is that Mr. Smith? 是史密斯先生吗？ ---Yes, this is he.(电话用语) 是的。 It might have been she.那或许是她。 【注】①在非正式英语，尤其是口语中，人称代词作be的表语时，通常可用其宾格形式代替主格。如：---Who is it? 谁呀？ ---It’s me.是我。 ②to be + 人称代词作主语的补足语时，人称代词用主格，作宾语的补足语时用宾格。如： I was thought to be she.人们认为我是她。= They thought me to be her. 2、宾格形式作宾语(动词的宾语或介词的宾语)。 I bought a present for them. = I bought them a present.我给他们买了件礼物。 Mind you, this is just you and me.听着，这事只能你知我知，绝不可外传。 3、在比较状语从句中，在不引起误解的前提下，有时用宾格代替主格(尤其其后有同位语“all”时)。 He is taller than I (或me).他比我高。 He is taller than us all.他比我们都高。 【注】若可能引起误解，就不能用宾格代替主格。如： He loves you more than I.他爱你胜过我爱你。 He loves you mare than me.他爱你胜过爱我。 4、用来表示感叹时，常用宾格形式。 Dear me! 哎呀/天哪! = Goodness me! (三)代词排列次序(1—每一人称；2—第二人称；3—第三人称) 1、单数：通常按2,3,1或是3,2,1人称排列。如： Mary and I are classmates. You, he and I are good friends. 2、复数：通常按1,2,3人称排列。如： We, you and they have been invited to the party. Both we and they happened to be there. 3、第三人称男女两性并用时，男先女后。如： He and she still don’t quite agree to this plan.
