小灵通是一名八年级的学生,她聪明好学,成绩很好．最近她想办一个“学习在线”专栏,专门帮助其他同学解答学习上的疑难问题．小灵通明知,要给别人一坏水,自己就要成为一条奔流不息的小河．所以,她最近在努力地学习反比例函数．听说她在学习这部分内容时也碰到了不少的疑难问题． PHS is an eighth-grade student. She is smart and studious, and she has good grades. Recently she wanted to do a “learning online” column, to help other students solve difficult problems in learning. PHS knowingly, to give someone a bad water, he will become an endless stream. So, she was trying hard to learn the inverse proportion function. I heard that she also encountered many difficult problems in learning this part.
