What are you going go do on next Monday
This coat is very shorter than that one.
I have much more apples than yours
I am sorry. I think I can free at six.
You'd better not to ask your mother,she'll be angry.
最好写一下为什么这样改
參考答案:1 what are you going to do on ...
be going to do 固定搭配
2 very 改Much
修饰比较级不用very ,用Much
3 Yours 改You
yours是名词性的，相当于your apples，这里用you 就可以了
4 free 前加上be
free 是形容词，一定要有be动词的
5 去掉to
had better do, had better not do something
这是固定搭配，不能加to，意思是最好做某事
