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.

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.
= It is important that she to the party.
⑶It takes sb. ... to do sth. 常译为＂做．．．要花费某人．．．＂。
Eg It took thousands of people many years to build the Great Wall.
(4)it’s up to sb to do sth 做某事由某人决定

句型：I like (enjoy, hate…) it when….
I would appreciate it if…
…see to(depend on/depend on/be fond of…) it that

A. this

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 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.

It-is...that结构归纳总结
“It is…that…”结构归纳总结 现行我们常会遇到“It is…that …”这一结构。如何理解这一句子结构，正确翻译句子，提高阅读能力是至关重要的。 一、“It is/was+形容词+that…”结构 在该结构中，it是引导词，作形式主语，从属连词that引导的是主语从句，在句中作真正的主语。例如： 1. It was right that the temple was rescued. 拯救这座寺庙是做得对的。 2. It was obvious that the matter had never been paid attention to.显然这件事一直没有被注意。 3. It is strange that she should have failed to see her own shortcomings. 真奇怪，她竟然没有看出自己的缺点。 在用法上，该结构与“It is+形容词+不定式复合结构”（即“It is+adj. +of sb.to do sth.”“It is+adj.+for sb.to do sth.”或“It is+adj.+for sth.to be done”）是一样的。有时主语从句也可与不定式复合结构互换使用。例如： 4. It's quite likely that a decision will be made before the end of the year.（It is quite likely for a decision to be made before the end of the year.）年底以前作出决定是完全可能的。 二、“It is+名词+that…”结构 5. It is no wonder that she is so ill.她病得这样厉害是不足为怪的。 6. It is a pity that you live at such a distance. 很遗憾，你住得那么远。 三、“It is+过去分词+that…”结构 7 .It was said that he found in music the peace which was missing in a world full of wars and killings.据说他从音乐里找到了在充满战争和屠杀的世界里所失去的和平。 8. It is decided that I will meet them at the airport.决定让我去机场接他们。 9. It is arranged that the class meeting will be held next week.根据安排班会于下周召开。 10.
