九年级it用法及练习
It的用法总结
在英语中,it有许多不同的用法,它既可以用作代词(如人称代词、非人称代词)，也可以用作引导词（作形式主语或形式宾语），还可以用来构成强调句型。
1.it用作代词
(1) 用作人称代词在句子中作主语或宾语；指前面已经提到过的事物、动物或人，且it指特定的事物；如果指前文中提到的事物中的任何一个，用one。one可以与any, each, every,
not等连用，但one不可代替不可数名词。
—Where's your car?
—It's in the garage. 你的汽车在哪儿呢？在车库里。(指代物品your car)
Did you hit it? 你打中了吗？(指代事件)
The baby cried when it was hungry.这婴儿饿时就哭。（指代婴儿，尤指性别不详或无所谓时）—Who is that?
—It's me. 是谁？我。(指一定情景中所确定的人或事物，此时相当于指示代词，代指this和that,有时也指人)
—What's this?
—It's a box. 这是什么？一只箱子。
(2) 作非人称代词表示天气、日期、时间、温度、距离、价值、路程、度量、自然现象与环境等。也可模糊地指一般情形或上文的部分或整个意思。译成汉语时，it通常不一定译出来。
It's a long time since they left. 他们走后很久了。
It's two miles to the beach.离海滨有两英里远。
That's just it—I can't work when you're making so much noise.原因就在这里——你弄出这么大的声音，我工作不了。
另外，需要注意两点：
（1）“It's time…”后面可以接不定式和介词短语表示“是做……的时候了”。如：
It's time for supper. It's time to have supper.
(2) “It's time…”后面还可以接一个从句，但是从句中的谓语动词一定要用过去式即虚拟语气，如：
It's time we had lunch.是我们吃饭的时候了。
It's time we started.是我们该出发的时候了。
2.it用作引导词
(1) 作形式主语由动词不定式、动词-ing短语或名词性从句担任主语的句子，常用it来作形式主语，而把真正的主语放在句子的后面。
It's not easy for us to learn English well. [句型为: It +be+形容词+（for sb.）to do sth.]
It's foolish of you to say that to her. [句型为: It +be+形容词+（of sb.）+to do sth.]
It's no use/good/help…sleeping too much. (句型为: It +be+名词+doing)
It's important that we be there on time.（句型为: It +be +形容词+that从句）
It's high time that Tom went to school. (句型为: It +be +time +that从句，从句中的动词用过去时)
It was the second time that he had telephoned me that day. [句型为: It +be+ the first(second,
third)time +that从句]（that从句中动词用完成时）
+that过去分词: It +be+句型为It was arranged that they should leave the following winter. (
从句)
It appears that the two leaders are holding secret talks. (句型为: It +不及物动词+that从句)
(2) 作形式宾语当宾语是动词不定式、动词-ing短语或名词性从句时，而宾语后又有宾语补足语，则需用it作形式宾语，将真正的宾语放到宾语补足语的后面。用于这种结构的动词有：feel, find, think, make, consider, take等。
Marx found it important to study the situation in Russia.马克思发现研究俄国的形势很重要。
I find it strange that she doesn't want to travel.她竟不想旅游,我觉得很奇怪。
I' ll make it clear to you that failure is the mother of success.我要告诉你们失败是成功之母。
3.it用在强调句型中
英语中，为了突出句子中的某一成分，达到强调或使人特别注意该成分的目的，人们常用“It
is/was+强调对象+who/whom/that….”句式把整个句子分割成前后两个部分，使之各自有自己的谓语动词，中间由that或who/whom连起来成为一个新句子。除强调人时用who,
whom外，其余情况都用连词that。被强调的对象仅限于句子的主语、宾语、宾语补足语和部分状语（包括状语从句），即除谓语和定语以外的句子成分。这部分状语主要包括地点状语、由before, when, after, not until等引起的时间状语从句、由because, because of引起的原因状语、由by引起的方式状语等。
当被强调的对象是人时，可用who, whom或that，其余情况一律用that; 当被强调对象在从句中做主语时用who/that,当被强调对象在从句中做宾语时用whom/that。
原句：My father did the experiment in the lab yesterday evening.昨天晚上我父亲在实验室做实验。It was my father did the experiment in the lab yesterday evening.昨天晚上是我父亲在实验室做实验。（强调主语）
It was the experiment that my father did in the lab yesterday evening.昨天晚上我父亲在实验室里做
的是实验。（强调宾语）
It was yesterday evening that my father did the experiment in the lab.我父亲是昨天晚上在实验室做
实验的。（强调时间状语）
It was in the lab that my father did the experiment yesterday evening.我父亲昨天晚上是在实验室里
做这个实验的。（强调地点状语）
另外，再注意两点：
（1）强调句如果还原成陈述句的话，句子成分是完整的，如果不完整，那必然是别的从句而不是强调句。
It was the town where we lived for three years.此句是定语从句，因为还原以后的句子为:
We lived the town for three years.缺少介词（in the town）, 而It was in the town that we
lived for three years.这就是一个强调句了。
（2）强调中心也可以是疑问词，这时要将疑问词置于句首，构成一个特殊疑问句。
Why is it that you want to leave so soon? 你到底为何这么早就要走？

It的用法、Therebe句型
期末专题练习——It的用法、There be句型 ［教学内容］ 第一部分It 的用法 概说：It是个非常简单的单词,但其用法却很灵活。 一、指代作用。It作句子的主语。 （一）It指前面已经提到过的人或事物。 1. What’s this? —It’s a chair. 2. Who is it? —It’s me. 提示：it代替上文提及的原物(复数用they)； one指代上文提及的、泛指的可数名词单数（复数ones）； that指代上文提及的定指的可数名词单数或不可数名词（复数those）。 （二）It指时间、季节。虚义。 1. What time is it? —It’s nine. 2. It’s time to go to school. Let’s go. 3. What day is today? —It’s Saturday. 4. What is the date today? —It is Oct. 1st. 5. What season is it? —It is summer. （三）It指气候。虚义。 1. It is cold in this room. 这个房间很冷。 2.

It的用法及典型句型归纳. 个人总结
It的用法及典型句型归纳 一、人称代词it的最基本用法是作代词，主要指刚提到的事物，想法，以避免重复;也可以指性别不明或性别被认为是不重要的人或动物；未指明但谈话双方都明白的事情或情况。 ①They watched the train until it disappeared in the distance. ②Is this your dog？No, it isn’t. ③I hate it when people talk with a full mouth.． 二、.非人称代词.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等： It is a lovely day, isn’t it? // It was nearly midnight when she came back. It is April First today. // It is some 3000 kilometers from A to B. It is three dollars. // Today it is 30 degrees centigrade. 三、作形式主语，替代主语从句，动词不定式，或动名词短语 1.作形式主语替代主语从句 ⑴It is clear ( obvious，true，possible，certain....) that ＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂ ⑵It is important ( necessary，right，strange，natural...) that + (should ) do (虚拟语气) ┅是重要的(必要的,对的,奇怪的,自然的┅) ⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that = sb / sth is said (reported/ believed /thought…) to do( to be doing/ to have done) sth ＂据说（据报道，据悉．．．）＂。 ⑷It is suggested ( advised/ ordered / demanded/ insisted/ commanded... ) that +(should ) do ＂据建议；有命令．． ⑸It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/... ) that that后的从句一般用虚拟语气（should + 动词原形），should可省去．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。 小练一下： It is very clear that he’s round and tall like a tree. = It is important that we (learn) English well. It is necessary that he (remember) these words. It is said that he has come to Beijing. = It is reported that another earth satellite has been put into orbit. = It is suggested that the meeting ( put off). It was ordered that we (arrive) there in two hours. It is a pity that such a thing ( happen) in your class. It is a pity that he (be) ill. 2.作形式主语替代不定式 . ⑴It is kind ( of sb. ) to do sth.= sb be kind to do sth.一般都是表示人的特性的形容词。如： bad /brave /careless/ clever /cruel / foolish / good （好心的）/ honest/ kind / lazy / modest/ naughty/ nice（有教养的）/polite/ rude / silly / stupid / wise ，等。 Eg. It is kind of you to give me a hand. = ⑵It is necessary ( for sb. ) to do sth. .不定式的逻辑主语是由for引起。常见的形容词有： Important/ necessary/ natural/ easy / safe / common / normal / hard / difficult / dangerous/ unusual/ rare / impossible / pleasant Eg. It is important for her to come to the party.
