-I like bands that______really cool clithes.-That's not relly impoant___me.

-I like bands that 【wear】really cool clothes. -That's not really impoant【to】me.
1.wears第三人称单数不对,本句的句子我喜欢穿着很酷衣服的乐队,这是一种状态,要用wear表示,put on仅仅是一个动作,不能表示状态.
2.be important to sb 对某人重要
be important for sb to do sth 对某人来说,做某事重要
两个短语的含义不同,强调的点也不同的
比如：This book is important to me ,这本书对我很重要
It is important for me to study hard.对我来说,努力学习很重要.
然后还有一点,for 不能单独用,只能是be important for sb to do sth 用在一起.
