我写了一篇英语作文,若按中考18分评分的话,可以得几分?还有,帮我修改一下全文好吗?
My Family Rules
As we all know,a nation has it's rule and a family also has one.In my home,I have a lot of rules.For example,playing the piano everday,do the home work more than2 hours.So I get tired of the family rules.I want to tell my parents some suggestions.If you would like me to be a good boy,you needn't give me a lot of rules and I'll do myself.Because I'm growing up.

答案

我很认真的评哦,不过有点小打击
"playing the piano everday, do the home work more than2 hours"前后不一致
"tell"和"suggestions"不能搭吧
“you needn't give me a lot of rules and I'll do myself."
“needn't”用“shouldn’t”比较好
“Because I'm growing up.”“grow up” 是个比较长的过程,用现在进行时不对.
另外,字数什么的,内容有没有缺不大清楚,书写规范等,要评分还应给出,分值和要求,以及题目.
现在扣分的话,【按我们老师的】,扣了有四五分吧.
