動詞不定式
①動賓關系：
I have a meeting to attend
注意：不定式為不及物動詞時，所修飾的名詞如果是地點、工具等，應有必要的介詞，如：
He found a good house to live in.
The child has nothing to worry about.
如果不定式修飾time， place， way，可以省略介詞：
He has no place to live.
This is the best way to work out this problem.
如果不定式所修飾名詞是不定式動作承受者，不定式可用主動式也可用被動式：
Have you got anything to send？ Have you got anything to be sent？
②說明所修飾名詞的內容：
We have made a plan to finish the work.
③被修飾名詞是不定式邏輯主語：
He is the first to get here.
(1)接不定式或動名詞在意思上有區別的動詞：
fmean to do想要(做某事)propose to do打算(做某事)
mean doing意味(做某事)propose doing建議(做某事)
forget to do忘記(要做的事)remember to do記得(要做某事)
forget doing忘記(已做的事)remember doing記得(已做過的事)
regret to do(對將要做的事)遺憾go on to do繼而(做另一件事)
regret doing(對已做過的事)后悔go on doing繼續(做原來的事)
fstop to do停下來去做另一件事
stop doing停止正在做的事
(2)下列動詞短語中的to是介詞，后面應接動名詞或名詞：
object to，resort to，react to，contribute to，look forward to，be accustomed to，be committed to.be exposed to，be subjected to，be devoted to，be dedicated to，be opposed to，be reconciled to，be contrary to
1. 分詞作定語
1) 分詞作定語既可以放在所修飾的詞之前，作前置定語，也可以放在所修飾的詞后面，作后置定語。其作用相當于一個定語從句。例如：
Where are the reserved seats？ (=Where are the seats which have been reserved？)
預定的座位在哪里？
This is a pressing problem. (=This is a problem which is pressing.)
這是一個緊迫的問題。
2) 分詞作后置定語可分為限制性(緊跟在所修飾的中心詞之后)和非限制性(用逗號與其所修飾的中心詞分開)兩種，其作用分別相當于一個限制性定語從句和非限制性定語從句。
例如：
The funds raised (= which have been raised) are mainly used for helping the homeless.
籌集的資金主要用來幫助那些無家可歸的人。
There are many students waiting (= who are waiting) to get examined.
有許多學生在等待檢查
