(完整版)It用法练习题及答案
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? －It‘s my teacher’s son．2) －Who is that gentleman?－It's my friend Tom．He(不可用It) wants to see you．2．用于表达天气、环境、时间、距离、季节等。
例如：1) It’s half an hour’s walk from here to our school．2) It‘s nice and warm here．3) But it's two o'clock now, and it's time for us to go to school．3．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.It’s no harm drinking running water in that area。
It’s 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：① It is a pity (a shame ,a fact ,a wonder ,a good thing,etc. )that…It is a shame that he didn’t pass the exam.② It is strange ( surprising,obvious ,true, good,possible,clear,etc. ) that… 。

“It”作形式主语和形式宾语的用法详解及习题演练
新希望英语语法精讲------“It”作形式主语和形式宾语“It”作形式主语和形式宾语的用法详解It作形式主语和形式宾语用法，是英语学习的主要语法项目之一。
无论是单项选择，还是完行填空，it 用法始终是反复考查的重、热点之一。
现将it在特殊句型中作形式主语和形式宾语用法，进行如下归纳分析，以供学习参考。
一、It 用作形式主语当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。
此时it只起先行引导作用，本身无词义。
e.g. It is wrong to tell a lie. (说谎是错误的。
) 〔It为to tell a lie的形式主语〕It is no use arguing about it. (争吵是没用的。
) 〔It为arguing about it的形式主语〕It is uncertain who will come. (谁要来还不确定。
) 〔It为who will come的形式主语〕It 作形式主语的常见句型：①It + be + 形容词+ to do sth. / doing / that ….e.g. It is very important to learn a foreign language. (学一门外语非常重要。
)It is useless crying over the spilt milk. (覆水难收。
)It was really surprising that she married a man like that.(她嫁给那样的男士真让人惊讶。
)②It + be +名词词组+ doing / that ….e.g. It is no good telling lies. (撒谎没好处。
)It is a pity that you didn’t go to see the film yesterday. (你昨天没看成那部电影真遗憾。
