1．動(dòng)詞不定式是一種非謂語(yǔ)動(dòng)詞，如to have, to work等, 在句中不能單獨(dú)作謂語(yǔ)。不定式符號(hào)“to”不是介詞，無(wú)詞義。不定式有一般、完成、進(jìn)行等幾種常用的形式，也有主動(dòng)和被動(dòng)語(yǔ)態(tài)的區(qū)別，職稱英語(yǔ)考題中不定式的被動(dòng)語(yǔ)態(tài)結(jié)構(gòu)是常見(jiàn)的考點(diǎn)， 以study為例：

 

 

2．不定式結(jié)構(gòu)中的動(dòng)詞仍然保持動(dòng)詞的特征，可帶賓語(yǔ)或狀語(yǔ)，構(gòu)成不定式短語(yǔ)。如：

to do shopping   購(gòu)物

to come back     回來(lái)

 

3．不定式的否定形式是在不定式前面加not, never等，如：

they told me not/never to open the window. 他們告訴我不要打開(kāi)窗戶。

 

4．不定式有時(shí)可直接與疑問(wèn)詞連用，如what, when, where, which, whom, why, whether, how等，如：

he wanted to know how to handle such a problem. 他想知道怎樣解決這個(gè)問(wèn)題。

he asked when to leave for home. 他問(wèn)什么時(shí)候出發(fā)回家。
