it 的用法
在看学生的雅思写作文章过程中，总会看到这样的文字，“college graduates are difficult to find jobs”，“parents realise the needs of their children is extremely important”，“students cannot focus on their study because of tiredness is a fact”，“Clearly, rush hours emerges in the early morning as well as early evening which is most busy in a day as a whole in London.”这几个句子，虽然长短不一，结构不同，话题各异，但是，学生对形式主语it的驾驭能力的欠缺，是可见一斑的。
二、形式主语
（一）什么是形式主语
作为形式主语的it并无实际语义，是为满足语法上的需要，避免句子头重脚轻，它代替的是句子的逻辑主语。
（二）形式主语it所在的句型类别
1、作不定式的形式主语
（1）句型
It is + a pity/a pleasure + to do sth.
It is + wrong/right/wise/cruel/naughty/selfish + of sb. + to do sth.
It is + necessary/hard/important/difficult/possible/common + for sb. + to do sth.（2）雅思范文写作实例
A. Beyond this, it is also of paramount importance to use theaters and museums as the “social classroom” of culture and history education.
B. I think it is by no means pointless, in any way, to try to keep traditions alive with technology. (Cambridge 3, P162, T ask 2)
C. It is difficult to say who has the right to judge whether children working is “wrong” or “valuable”. (Cambridge 3, P164, T ask 2)
D. …, it is important to remember that children need to develop skills other than
intellectual ones, and …(Cambridge 3, P168, T ask 2)

H. They may think that it is better to continue in a particular job, or to do sth completely different from from a university course. (Cambridge 5, P165, Task 2)
据本人统计，剑桥官方的雅思真题（剑3—剑8）几乎每一篇T ask2考官范文中，都有所使用，甚至在有的文章中出现三次之多。
（3）学生写作实例
实例1：Many people, if not most, are strong believer in the claim that regard children go to work as completely wrong,while others hold the opposite opinion.修改建议：it is completely wrong for children to go to work.
实例2：They have to complete their homework conscientiously within limited time and difficult to discover the problems in studies.
修改建议：thus it is difficult to discover their problems in study.
实例3：College graduates are difficult to find jobs.
修改建议：It is difficult for college graduates to find jobs.
实例4：Parents realise the needs of their children is extremely important.
修改建议：It is extremely important for parents to realise the needs of their children. It is extremely important that parents realise the needs of their children.
2、作动名词的形式主语
（1）句型
It is + (no) use/good/useless/a waste of time/energy/efforts + doing sth.
It is + good/useless/hard/foolish/enjoyable/worthwhile + doing sth.
（2）雅思范文写作实例
A. For instance, children usually pay attention to match their clothing and toys; in fact, it is really worth competing thing that their study is being ignored.
B. Some parents believe that it is no use having second education for their kids.（3）学生作文实例
实例：Particular countries and individuals deals with environmental issues are no use. 修改建议：It is no use dealing with environmental issues by particular countries and indivuduals.
3、作主语从句的形式主语
（1）句型
It is + (adj) n./(adv.) adj./(adv.)v-ed + that……
It + seems/happens/appears/matters//strikes/occurs(突然想起) + that……
It is + said/reported/believed/(universally/widely) accepted/announced/estimated/acknowledged + that……
It + must be admitted/stressed out + that…/It + cannot be denied + that….../It + can be foreseen + that……
It + goes without saying + that…
（2）雅思范文实例
A. It is an understandable fact that many employers may prefer to use the services of children simply to save money by paying them less than adults and it is this type of exploitation tht should be discouraged. (Cambridge 3, P164, T ask 2)
B. Admittedly, it is common sense that a person without cooperative spirit will be difficult to survive in the modern society.

H. It seems that the experiences we have in life are so unpredictable and so powerful, that they can boost or overide other influences, …(Cambridge 5, P169, Task 2)
（3）学生写作实例
实例1：It is quite obvious/evident/apparent that the quantity of families who tends to go outside and infuse fresh oxygen into their lungs is growing steadily.
实例2：It is universally acknowledged that the best way to arouse people’s love to
our nature, who has devoted herself too much to human being’s development while has received barely anything till now, is to let them see the beauty of hers by themselves.
这是XVCC23强化班里一位基础较好的学生的写作实例，其中的语法、措辞方面的错误已经进行了修改。
实例3：Clearly, rush hours emerges in the early morning as well as (in the) early evening which is most busy/the busiest in a day as a whole in London.
修改建议：这个句子的结构应该是无可厚非的（语法就不说啦），但是，按照雅思评分的标准，句式稍微做一下调整，会更漂亮：如：It is clear that rush hours emerge in the early morning as well as in the early evening which is most busy/the busiest in a day as a whole in London.或者改成It is demonstrated that rush hours emerge in the early morning as well as in the early evening which is most busy/the busiest in a day as a whole in London.这样一个小小的调整，其句子修改前后的效果是显而易见的。
（三）it作形式主语的特征分析
根据以上对it作形式主语的句型结构的解析，对雅思写作范文、尤其是官方考官范文的分析，以及对学生写作过程中出现的it使用状况的详细解读可知：相比较于名词性从句、定语从句、状语从句的复杂性和多边性，it作为形式主语的句式结构可谓简明扼要，学生掌握起来应该说是得心应手的。
（四）不能正确使用it形式主语的原因
在信息编排时，英语句子遵循“end focus”的原则，即旧信息在前，新信息在后“old information+new information”；但是，当句子主语结构较长，容易使句子产生“head weight”的感觉时，句子结构则遵循“end weight”的原则，即，把较长的主语全部置于句子尾部。前面空掉的主语位置用it来代替，担当形式主语的功能。
而汉语并不具有这类明显的特征，学生对英汉两种语言结构差异知之甚少，或者略有所知，
在真正的运用中，也未必能够正确的体现出来。多数学生都本着汉语式的思维，一遇到“某
人做某事是怎么样的/是什么”就习惯性地写成sb. + is/are +adj./n. + to do sth.
三、总结
建议学生在雅思学习中，采取步步为营的四步走战略战术，循序渐进：首先，记住句型结构；其次，模仿写作；之后，进行独立创作；最后，形成属于自己的模板句型。作为雅思写作学习中可控制的因素，我们可以培养句式运用的习惯，使习惯称为自然。为了我们雅思的学习
这个努力是值得的，it pays in the long run.

2011届高考英语一轮复习讲解：it的用法
2011届高考英语一轮复习讲解：it的用法【知识要点】 It的用法 （一）作人称代词 1、it代替前面（或后面）的单数名词或分句等所表示的事物。 e.g. You cannot eat your cake but have it.（it代替前面的cake） Although we cannot see it, there is air all around us. （it代替后面的air） They say he has left town, but I don’t believe it.（it代替前面They…town分句中的情况） 2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree） The baby cried because it was hungry. （it代替前面的baby） 3、在某些习惯说法中，可以代替人。 e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me. ---- Who are singing? ---- It is the children. ---- The light is still on in the lab. It must be the third-year students doing the experiment. 4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China） The climate of South China is much better than that of Japan.（that指the climate）（二）作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the f actory. It is eighteen square metres in area. What does it matter? （三）作强调词，构成强调结构

高考语法it用法详解
一. it作人称代词 在特定的环境中，it可指人，如指婴儿、性别不详或身份不明的人。 e.g. 1. The baby stopped crying as soon as it saw the woman.（指婴儿） 2. —Who is it? —It’s me.（性别不详或身份不明） 二. it作形式主语或形式宾语 it可以作形式主语或形式宾语而把真正的主语或宾语后置。 1. 用it作形式主语的情况： (1) It＋系动词＋形容词＋that从句 It is necessary/important/surprising/strange＋that从句，从句中谓语动词常用“should＋动词原形”形式，且should可省略。 (2) It＋系动词＋名词＋that从句 It is a pity/a shame/good news/a fact/an honour/a wonder/no wonder/our duty＋that从句。 e.g. It’s no wonder that you’ve achieved so much success. 难怪你取得了如此大的成功。 (3) It＋不及物动词＋that从句 It seems/happened/turned out /occurs/appears＋that从句。 e.g. It happened that he was out when I called on him. 当我去拜访他的时候，碰巧他出去了。
(4) It＋系动词＋过去分词＋that从句 It is said /reported/ announced/ believed/ thought/ well known/ hoped/ pointed out/ found out/ suggested/ ordered/ advised/ requested/ insisted/ required/ demanded＋that从句。 e.g. It’s said that they have succeeded in carrying out this experiment.据说他成功的进行了这次实验。 【注意】在“It is suggested/advised/ordered/requested/insisted/required/demanded＋that从句”结构中，从句要用虚拟语气，即谓语动词用“should＋动词原形”，should可省略。 e.g. It is suggested that you (should) spend more time in studying English. 建议你花更多时间学习英语。 (5) 其他句型，如It doesn’t matter.../It makes no difference...等。 e.g. It doesn’t matter what you wear, as long as you look neat and tidy.你穿什么不重要，只要看上去整洁就可以。 It makes no difference to me whether you go or not. 你去或不去对我来说都没有区别。 2. it作形式宾语的情况 (1)动词find, feel, think, consider, make, believe等后有宾语补足语时，则需要用it作形式宾语，把作为真正宾语的that从句后置。
