“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。
高中英语it 用作形式主语宾语的用法及24个it句式盘点总结(有习题)
高中英语it 用作形式主语/宾语的用法及24个it句式盘点总结一、用作形式主语当不定式、动名词、从句等用作主语时，避免头重脚轻，通常在句首使用形式主语it，而把真正的主语放在句子末尾。
如：It is stupid to do such a thing. 做这种事真蠢。
It’s no good sitting up too late. 熬夜没有好处。
It is necessary that he should be sent there at once. 有必要马上派他到那里去。
注：类似以下句子中的it也可视为形式主语：It happened that the harvest was bad in 1988. 碰巧1988年的收成很不好。
It seems that she is afraid to tell them about it. 似乎她怕将此事告诉他们。
二、用作形式宾语当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时，就应在宾语补足语前使用形式宾语，而将真正的宾语移至句末。
如：I’ve made it a rule never to hurry. 我已养成凡事从容不迫的习惯。
Do you think it possible to root out crime? 你认为可以根除犯罪吗?He found it difficult to breathe at high altitudes. 他觉得在高空呼吸困难。
注：通常意义的形式宾语主要见于真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形，即用于“动词+it+宾语补足语+真正的宾语”这样的结构，但以下两类形式宾语却比较特殊，其后没有宾语补足语：1. 由于介词后通常不能直接跟that从句作宾语，有个别特殊结构就在介词后先接it作形式宾语，再跟that从句。
如：You may depend on it that it is true. 你可以相信这是真的。

it作形式主语时，可以代替三种形式：不定式、动名词和主语从句。
⒈ it代替不定式短语 常用于下列句型中：It + be +形容词 + (for/of sb.) to do sth. It + be + 名词 + to do sth. It takes sb. some time to do sth. 干…花了某人…时间 It’s up to sb. to do sth. 干…是某人的职责或义务 ①It is everyone’s duty to obey the law. 遵守法律是每个人的义务。

（ it作形式主语, 代替不定式短语to build the bridge） ◆ It be + 形容词+ for sb. to do sth.与It be + 形容词+of sb. to do sth.： 如果句型中的形容词描述的是sb.的品质、品格，在逻辑上可以作sb.的表语，则sb.前应用介词of，否则就用for。
①It’s necessary for us to use a short-wave radio to pick up the programmes. 我们用一台短波收音机收听这些节目是必要的。
③It’s kind of you to help me. 感谢你对我的帮助。
（= You are kind to help me. ） ④It was foolish of him to give up the job. 他放弃那工作是愚蠢的。

①It is no good/ use having a car if you can’t drive. 如果你不会开车，有车也没用。
