B to write on 这句话是用不定式做定语，放在被修饰词的后面，但是被修饰词要与不定式有主谓，动宾关系，如i need some books to read,water to drink / a person to share my happiness and sorrow等,这是动宾关系，和主谓关系，read the book,drink the water,the person shares my happiness 但是如果一些不及物东词不能构成动宾关系，需要介词帮助，如i need a room to live in/ i need a friend to talk with . 所以i need paper to write on/ i need a pen to wrtie with

B to write on
to write on the paper是个固定词组

选A

B，首先need to do sth,是固定搭配，然后这里a piece of paper 做on 的宾语，其实可看成need to write on a piece of paper,译成：他需要写在一张纸上。

选B 因为，做这题要看动宾关系，要是后面有pen 这意思为用什么工具来写，要是什么都没，实则省略了something,意思为在纸上写字。所以本体翻译为，他需要一张纸来写东西。

B，need sth to do 是固定搭配，write sth on sth也是固定搭配，在作为定语表示@某一种用途@时，后面的介词是不能省略的，故选B

B 首先是 to表示目的，而write on paper是一个用法，on 是不能省略的，也不能用with
