One possible version：

Nowadays more and more parents choose to reward their children with money for the progress they have made in their studies.

Why? Most parents devote themselves to their careers due to fierce competition, thus caring less about their children.However, I don' t think this is a practical and wise choice.Firstly, if children are always rewarded with money for high marks, their attention will be focused on money instead of the pleasure of studying.

Some of them will stop working hard as soon as they get what they want.Secondly, too much money will spoil the children, for they are too young to use money properly.

I think a hug and a kiss will work better for children than money.Money may do them more harm than good.
