It的用法It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。一、要点点拔1代替上文中提到过的人或事物。指代人时，一般用于小孩或身份不十分明朗的人。1) Who is the baby? Its my teachers son2) Who is that gentleman? Its my friend TomHe(不可用It) wants to see you2用于表达天气、环境、时间、距离、季节等。例如： 1) Its half an hours walk from here to our school2) Its nice and warm here3) But its two oclock now, and its time for us to go to school3用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。 1).It 替代真正的主语动词不定式短语.It is easier to say than to do .It is a good act to help the others. 2).it 替代真正的主语动名词短语,以动名词短语做主语的句子，主要在以no good, no use, no harm, dangerous, foolish 等词作表语的句中. Its no harm drinking running water in that area。 Its foolish talking like that.3).it 替代从句作主语，用从句做主语的带it 的句子很多,常见的有下面几类： It is a pity (a shame ,a fact ,a wonder ,a good thing, etc. ) thatIt is a shame that he didnt pass the exam. It is strange ( surprising, obvious,true, good, possible, clear, etc.) that 。It was clear that they had no desire for peace. It seems (happened ,turned out, etc.)thatIt seemed that things were not as they expected. It is said( decided ,expected ,etc)that It is said that the tickets have been sold out .4.用作形式宾语。当复合宾语中的宾语是不定式,ing短语或从句往往用it作形式宾语,而将真正的宾语移至句末,句子重心后移。1) We find it difficult to learn English well in such a short time2) We think it no use crying over spilt milk3) We made it clear when and where we were going to have the meeting二、综合练习（一）英文翻译成中文1.Its easy for me to learn English.2.It is difficult for me to drink so much water in one hour.3.Its difficult for the CLEVER boy to swim.4.It is easy for us to join the football team.5、Its dangerous for us to swim IN THE SEA .6.It is difficult for Lulu to cook some delicious food.7Its happy for woman teacher to teach us.8.It is easy for him to go different companies.（二）英文翻译成英文1、对于那个胖孩子来说骑车是困难的。2、对于玛丽来说做数学作业是没用的。3、对于那个矮男孩来说加入篮球队是勇敢的。4、把英语学好是有用的。5、对于那个老人来说爬树是危险的。6、保持我们的环境干净和整洁是非常重要的。7、对于那个笨女孩来说找到答案是很困难的。8、对于那个女孩来说放学去购物是不可能的。【参考答案】（一）英文翻译成中文1、对于我来说学习英语是很容易的。2、对于我来说在一个小时之内喝这么多水是难的。3、对于那个聪明的男孩来说游泳是很困难4、对于我们来说加入这个足球队是容易的。5、对于我们来说游泳是危险的。6、对于露露来说做一些美味的食物是难的。 7、对于那个女老师来说教我们是快乐的。8、对于他来说去不同的公司是容易的。（二）中文翻译成英文1.Its difficult for the fat boy to ride the bike. 2.It is not useful for Mary to do the math homework.3.Its brave for the short boy to join the basketball team.4.It is useful to study English well.8.It is impossible for the girl to go shopping after school。7.Its difficult for the stupid girl to find answer. 5.Its dangerous for the old man to climb the tree. 6.It is very important to keep our environment clea
