You'd better yourself.A.be not too sure of B.not be too sure of
问题描述：
You'd better yourself.A.be not too sure of B.not be too sure of
It's hard me.A.so; to B.too; for C.so; for D.too; to
答
had better 后加do sth 或者not do sth
对我来说太困难了,表达用too hard/difficult for me,用so 应有上下文
所以选B B
希望帮到你too 表示“太...”有过了头的意思,所以含否定意味.
so 表示"很...",只是一种单纯的感叹,所以含肯定意味.
