1.不定式的一般式(t+动词原形)——动作通常与谓语表示的动作同时或几乎同时发生，或是在它之后发生。
He appears t be very happy. T catch the train, we’ d better hurry t the statin by taxi.
(t catch the train 发生在 hurry t the statin 之后)
2.不定式的进行式 （t be +ding)表示正在进行或与谓语表示的动作同时发生的动作。 It happened t be raining when I gt there. 我到达那里的时候，碰巧在下雨。
3.不定式的完成式(t have +dne)不定式的完成式表示的动作在谓语表示的动作之前发生。 I’m srry t have lst yur key. 我很抱歉把你的钥匙弄丢了。
4.不定式的完成进行式 （t have been +ding)不定式的完成进行式表示的动作在谓语表示的动作之前发生并且一直持续，并且仍在进行。 He was said t have been living in Lndn fr twenty years.据说他在伦敦一直住了20年。
5.不定式的被动语态当不定式逻辑上的主语是这个不定式表示的动作的承受者时，不定式一般要用被动形式。不定式的被动形式根据其与谓语动作发生的先后关系，有一般式和完成式两种。
(1)一般式(t be dne) These are the bks t be given ut t the students.这些是要发给学生的书。
(2)完成式(t have been dne) The nvel is said t have been translated int many languages.据说这部小说已被译成多种语言

动词不定式作表语和v-ing作表语的区别
动词不定式和v-ing作表语时，要注意与句子的主语在形式上保持一致， 若句子的主语为v-ing，则表语也应使用v-ing； 若主语为动词不定式，则表语也应使用动词不定式。 T see is t believe. = Seeing is believing.动词不定式和v-ing作表语时可换用，但以下情况除外:当动词所表达的是某一特定的行为，尤其是将来的行为或有待于实现的行为时，通常用动词不定式作表语。 Her best wish is t put her new ideas int practice.若动词所表达的并不强调动作，而是表示主语的内容，则通常用v-ing作表语。 My favrite sprt is swimming. What I hate mst is being laughed at.
