初中英语动词不定式用法全面解析(动词不定式的用法初中)

导语：初中英语小知识（六）—-动词不定式用法

动词不定式的用法：

一、动词不定式由：“to+动词原形”构成，在句子中可以作主语、宾语、宾语补足语、状语、定义和表语。如：

To play the piano well needs lots of practice.(作主语)

This story tells us that we should learn to share and give.(作宾语)

My parents always encourage me try new things.(作宾补)

We set off early in the morning to avoid the busy traffic.(作状语)

Would you please give me some paper to write on?(作定语)

The purpose of the activity is to raise money for the poor children.(作表语)

二、动词不定式作主语时，常由it代替它作形式主语，而将真正的主语（不定式短语）后移。如：

It’s necessary for you to take some food and drinks.

I is really careless of you to make such a mistake.

三、在“动词find\think\feel+it +形容词+动词不定式”结构中，it是形式宾语，真正的宾语是后面的动词不定式。如：

Simon finds it hard to make friends with other children.

四、动词不定式可用在be动词后作表语，主语通常是wish\job\dream\plan\goal等词。

如：Her dream is to take part in the Olympic Games one day.

五、动词不定式作定语时，通常位于它所修饰的名词或代词之后。如：

Do you have anything to say on the question?
