動詞不定式作定語,放在所修飾的名詞或代詞后.與所修飾名詞有如下關系:

　　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.
