不定式
动词不定式(to+动词原形)是一种非谓语动词形式,它不能单独作谓语,但可以有自己的宾语、状语、补足语等,并和它们一起构成不定式短语,在句中作主语、谓语、表语、宾语、定语、状语和补足语,动词不定式也有时态和语态的变化,是三级常考点之一。

不定式语法不定式作主语
不定式可以作主语,不定式作主语谓语用单数:
promise appears advisable.
To stop the work now seems impossible.
但在更多情况下都用“it”作先行主语, 而把不定式这个真正的主语放到句子后面去, 这样可使主语不至显得太长, 避免头重脚轻的现象, 常见的这类句子有以下几种:
