第一部分內(nèi)容：動詞不定式的用法
動詞不定式的句法功能
主語
To learn English is not easy for us.＝It is not easy for us to learn English.對我們來說學(xué)英語不容易。
動詞不定式作主語時，常轉(zhuǎn)化為用it作形式主語，而把不定式放在后面。
表語
My work is to clean the room every day.＝To clean the room every day is my work.每天打掃房間是我的工作。
多數(shù)情況下，不定式作表語可轉(zhuǎn)換為作主語。
賓語
—What sports does he like to play?
他喜歡做什么運動？
—He likes to play basketball.
他喜歡打籃球。
只能作某些動詞的賓語，一般不作介詞的賓語。
賓補(bǔ)
She asked me not to speak Chinese in English class.在英語課上她讓我不要講漢語。
在make，let，see，hear，watch 等使役、感官動詞后，作賓補(bǔ)的不定式省略to。
定語
Have you got anything to say？你有要說的嗎？
不定式作定語，要放在被修飾詞的后面。
狀語
I'm sorry to trouble you.(表原因)打擾你了，很抱歉。
I went to the library to study English.(表目的)我去圖書館學(xué)英語。
不定式作狀語，其邏輯主語要和句子的主語一致。
注意（1）不定式通常有三種時態(tài)形式：一般式，進(jìn)行式和完成式。但是不能作謂語�！�
(2)不定式的否定形式是在to的前面直接加not。
(3)不定式可以和疑問詞who，which，what，when，how，where(why除外)等連用，構(gòu)成不定式短語，在句子中作主語、賓語或表語等。
