非谓语动词作定语　(1)现在分词作定语　现在分词的主动式作定语与所修饰的名词之间存在逻辑上的主谓关系，表示该动作的主动和进行。现在分词的被动式作定语时，与所修饰名词之间存在逻辑上的动宾关系，表示该动作正在被执行。
(2)过去分词作定语　过去分词作定语时，与它所修饰的名词在逻辑上存在动宾关系，表示该动作的被动或完成。(3)不定式作定语　①不定式作定语时，通常放在所修饰词之后，表示将来的动作。不定式与其所修饰的词之间往往是动宾关系，若该不定式是不及物动词，则其后应有必要的介词。
②被修饰的名词是抽象名词时，用不定式作定语，常见的抽象名词：ability，chance，idea，fact，excuse，prmise，reply，attempt，belief，way，reasn，mment，time等。③the first，the secnd，the last，the next，the nly等作名词或者它们作形容词修饰名词或代词时，常用不定式作定语。
