动词不定式作定语,放在所修饰的名词或代词后.与所修饰名词有如下关系:

　　①动宾关系

　　I have a meeting to attend

　　注意:不定式为不及物动词时,所修饰的名词如果是地点、工具等,应有必要的介词,如:

　　He found a good house to live in.

　　The child has nothing to worry about.

　　如果不定式修饰time, place, way,可以省略介词:

　　He has no place to live.

　　This is the best way to work out this problem.

　　如果不定式所修饰名词是不定式动作承受者,不定式可用主动式也可用被动式:

　　Have you got anything to send? Have you got anything to be sent?

　　②说明所修饰名词的内容:

　　We have made a plan to finish the work.

　　③被修饰名词是不定式逻辑主语:

　　He is the first to get here.
