l         動詞不定式:
ⅰ.動詞不定式的形式
1．動詞不定式是一種非謂語動詞，如to have, to work等, 在句中不能單獨作謂語。不定式符號“to”不是介詞，無詞義。不定式有一般、完成、進(jìn)行等幾種常用的形式，也有主動和被動語態(tài)的區(qū)別，職稱英語考題中不定式的被動語態(tài)結(jié)構(gòu)是常見的考點， 以study為例：
 
 
主動
被動
一般式
to study
to be studied
進(jìn)行式
to be studying
 
完成式
to have studied
to have been studied
 
2．不定式結(jié)構(gòu)中的動詞仍然保持動詞的特征，可帶賓語或狀語，構(gòu)成不定式短語。如：
to do shopping   購物
to come back     回來
 
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窗戶。
 
4．不定式有時可直接與疑問詞連用，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問題。
he asked when to leave for home. 他問什么時候出發(fā)回家。
