动词不定式作定语

动词不定式作定语，一般置于被修饰的名词或代词后面，与名词或代词之间常有一定的逻辑关系。具体如下：

1)名词或代词为动词不定式的逻辑主语。如：

Wendywasthefirstonetoarriveatschool.

2)名词或代词为动词不定式的逻辑宾语。如：

Ihaveameetingtoattend.

如果动词不定式是不及物动词，需加介词才能与名词或代词之间构成动宾关系。如：

Thisisagoodtopictotalkabout.

3)名词与动词不定式是同位关系。如：

Sheexpressedawishtomakeachange.

4)动词不定式作定语，有被动形式。如：

Thehousetobebuilttherewillbealibrary.
