一、不定式定语和被修饰词（名词或代词）之间是逻辑动宾或逻辑介宾关系。举例：

New York’s a place to visit.纽约是个游览的好地方。《韦氏词典》

He has got many things to do. 他有许多要做的事情。

当不定式中的动词与所修饰的名词或代词构成动宾关系且动词为不及物动词时，需用“不定式+介词”的结构，这种情况下的介词不能省略。

There are some things to be grateful for.有一些事应该为之表示感激。

二、不定式定语和被修饰词之间是语义上的主谓关系

1.如果被修饰前有序数词、the next、the last、the only 等修饰词的时候，则不定式定语和被修饰词之间是逻辑主谓关系。举例：

2.常见的不定式定语和被修饰词之间是语义上的主谓关系

三、某些动词或形容词后可接不定式时，它相应的同根名词也常用不定式做定语，即被修饰词是动词派生的抽象名词或形容词派生的抽象名词时，一般用不定式作为后置定语。举例：

还有一些常见名词：way，time，reason，chance，opportunity，need，wish，effort，right，ambition后常常接不定式作定语。
