Question

动词不定式的用法？

what he needs is the shirt of a happy person to wear.
解释一下to wear
并造两个同类动词不定式用法的句子

Answer 1

to wear 是 shirt (of a happy person) 的后置定语，二者之间是动宾关系。What he needs is the shirt of a happy person to wear 意思是 “他所需要的是一件快乐的人穿的衬衫”。

不定式充当后置定语与被修饰词有三种关系：
*主谓关系：He is the first to come. (first 是 to come 的逻辑主语)
*动宾关系：本题 (shirt 是 to wear 的逻辑宾语)
*动状关系：This is the way to do it. (the way 是 to do it 的方式状语)
