helpful to 和 heplful for 都有"有助于"的意思，但 helpful to 较常用于接sb，而 helpful for也可以接sb，但多用于接sth或doing sth，表示"对....有益"。

例： Swimming is helpful for bones that are porous and weak.
游泳有助于改善骨质疏松和骨骼脆弱。

本系统已在实际业务工作中投入使用，有助于提高工作效率。

helpful for sb 的情况(sb一般是第一/二/三人称的主格或宾格)：

1、I think it's helpful for me to learn English well.
我认为它有助于我把英语学得更好。

2、Don't throw it, it is helpful for us to repair the bike.
别扔了它，它对我们修自行车有帮助。

3、I hope the two wise scholars'ideas on learning can be helpful for you.

help to sb的指向性较强，强调帮助的对向性，“什么”对“什么人”是“有用的、有帮助的、有益处的”。

例：The following information may be helpful to readers.

对某人有帮助的句型应该是be helpful to somebody而不是必须的。
