do better为什么better是well的比较级 是had better to do还是had better do 是be better do 还是better to do . 是had better do sth还是have better do sth 是do you feeling better 还是 do you feel better? you`d better to do sth究竟是you'd better to do sth还是you'd better do sth,为什么! 最好做.是better to do /better doing还是better do 最好做.是better to do /better doing还是better do i'm sure that i'll do better同义句怎么是i'm sure to do better,可否为i'm sure of doing better为什么 had better not do?had not better do?为什么我们高三复习那本单词书上写的是had not better do?不是应该是had better not Better Better better better had better do 为什么要用had?不是have better do had better do=? You will do better next time 为什么要用do better为什么要用do better 不用do well 或do good Given more time ,I can do it better这是一个省略句,原句是if i was given more time, i can do it better.为什么可以省略?
