動(dòng)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(guān)系:
    ①動(dòng)賓關(guān)系:
    I have a meeting to attend
    注意:不定式為不及物動(dòng)詞時(shí),所修飾的名詞如果是地點(diǎn)、工具等,應(yīng)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(dòng)作承受者,不定式可用主動(dòng)式也可用被動(dòng)式:
    Have you got anything to send? 　Have you got anything to be sent?
    ②說明所修飾名詞的內(nèi)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.
