定义
不定式是动词的一种非限定形式,由 “to+动词原形” 构成，没有人称和 数的变化，在句中不能独立作谓语。 但不定式具有名词、形容词和副词的特 征，在句中可以作主语、宾语、补足语、 表语、定语、状语等。
一. 不定式在句中的功能
1. 作主语:
眼见为实. To see is to believe. 为避免句子出现 “头重脚轻”现象，常用it 做形式主语，将真正主语的不定式后置。 要学好英语不是那么容易的。 e.g. It is not easy to learn English well.
2. 作宾语
她喜欢谈论这件事情。 e.g. She loves to talk about the matter. 他希望不久能找到工作。 He hopes to find a job soon. 他答应不把这事告诉任何人。 He promised not to tell anyone about it.
2) 思考: 巧记哪些动名词与不定式的动词 意思有较大的区别？
记住要努力，（remember want try ) 需要别忘记； (need forget ) 后悔没尽力， ( regret try ) 意思要停止。 ( mean require stop )

定义
不定式是动词的一种非限定形式,由 “to+动词原形” 构成，没有人称和 数的变化，在句中不能独立作谓语。 但不定式具有名词、形容词和副词的特 征，在句中可以作主语、宾语、补足语、 表语、定语、状语等。
一. 不定式在句中的功能
1. 作主语:
眼见为实. To see is to believe. 为避免句子出现 “头重脚轻”现象，常用it 做形式主语，将真正主语的不定式后置。 要学好英语不是那么容易的。 e.g. It is not easy to learn English well.
2. 作宾语
她喜欢谈论这件事情。 e.g. She loves to talk about the matter. 他希望不久能找到工作。 He hopes to find a job soon. 他答应不把这事告诉任何人。 He promised not to tell anyone about it.
