英语老师帮忙看下我写的这篇短文哈,有错误的地方帮忙改下,或者怎么表达会更好.
作文题是
假设你是华华,与英国网友汤姆约定用对方的母语通信,以提高各自的外语水平.最近你收到汤姆的电子邮件（附后）,发现有一个成语使用不当.请根据下列要点,用英文回一封电子邮件.
要点:
1．不应使用 “无所不为”,应使用 “无所事事”;
2．说明这两个成语的用法;
3．给予鼓励.
注意:1.词数为100左右;
2.参考释义:无所不为一do all kinds of bad things
无所事事一have nothing to do
3.除以上两个成语外,邮件中不得使用其它汉字或拼音;
4.电子邮件的开头和结尾已为你写好（不计人你所写词数）,但不得抄人答题卡.
附（汤姆的邮件）:
近几天在忙什么事?有什么有意思的事吗?我们的学校放假了,所以这几天在家无所不为,饱食终日,只好上网发伊妹儿.没意思.我决定找份工作,做个自食其力的人.祝好!
汤姆

Hi!Tom

…
Hope you’ll find a good job soon.

我的作文..(开头结尾省去）
In general,this e-mail you wrote is prefect,but only have a little problem,I think it is likely ''无所事事''that you would express,rather than ''无所不为'',''无所不为''means do all kinds of bad things,you see,if you put it on your composition,it will make no sense at all,however,''无所事事''means have nothing to do,do you kown it As a matterof fact,Chinese,most people to say,is not more than difficult,only if you try your best to make yourself understood,it is easy
Finally,I hope you can make your dream comes true,hope you will happy all the time
