问题描述：
win basketball games 为什么要加to
为什么win前面要加to?还有这一句the goal is to throw the ball 为什么又要to 还有please give the book to me 是用to后面为什么又用for my did bought a bsketball for my brother
答
to win basketball games 中的to后面的句子是表示目的状语.
the goal is to throw the bal 中的to后面的句子是做定语.
please give thebook to me give sth.to sb.是一个固定短语,to 不可省略.
my dad bought a bsketball for my brother 中boughr的动词原形是buy buy sth.to sb.也是固定短语,不可省略 .
你第四个我还是不明白buy sth. to sb是固定短语的话为什么还要用forbuy sth. for sb, 是为某人买某物buy sth. tosb.是给某人买某物定语怎么用？是什么
