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

英语it的用法及练习

it的用法及练习 一、概述 在英语中,it的使用相当广泛,它既可用作代词,如人称代词(personal it)、指示代词(demonstrative it)及非人称代词(impersonal it), 也可用作引导词(anticipatory it)和强调结构中的强调词(emphatic it) Someone is ringing the doorbell. Go and see who it is.有人在按门铃。去看看是谁。(人称代词)What’s this?这是什么? It’s a book.这是一本书。(指示代词) What a long way it is from Beijing to London! 从北京到伦敦真远。(非人称代词) It's best to plant trees in spring because it's warmer.春天是植树的最佳时节,因为天气更暖和。(作引导词) It was I who met him in the park last week. 是我上星期在公园遇到他的。(强调结构中的强调词) 二、it作代词 1、用作人称代词(personal it) 代替前文提到过的事物,it作真实主语或宾语。 The frog is not a warm-blooded animal. It is a cold-blooded one.青蛙不是温血动物,它是冷血动物。My pen is missing. I can't find it anywhere. 我的笔丢了,我哪儿也找不到它了。 I won't be back tonight.

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.
