动词不定式
动词不定式是我们经常提到的一个语法术语,它看起来很高深莫测的样子,其实
并不可怕。下面让我们一起来揭开它的神秘面纱吧!
一、基本形式:to+动词原形。
否定式:not+基本形式(短语)。
当需要表明动词不定式中的这个动作是谁发出时,我们可以用带逻辑主语的
不定式:for sb+基本形式(短语),如:for us to finish the work。
二、用法
1.做宾语
I began to learn English last year
2.做宾语补足语

【注意】当动词不定式做主语时,常用t做形式主语,做主语的动词不定式常常
放在后面。It's necessary to study hard.
