It is+adj.+of sb.+to do sth中的adj.跟sb.有关,这个adj.是用来形容sb.的,表示某人这么做真是太adj.了．你会发现在这个句型中你把sb.和adj.提出来可以造个句sb.is(are) adj.如It‘s very kind of you to help me.把...不是of sb.比如That's important to me.意思是那对我来说很重要。那么它和It's important for me有什么区别it is important( for somebody) to do sthg. 他人或个人认 为做一件事很重要有较强的客观性 eg. it is important for people to read 读书对人们来说很重要（但可能有一部份人不这么想）sth is important to sb.是个人认为重要 eg.money is important to her 她把 钱看的很重这就是区别 两个用法都对
