急！英语短文改错，有10处错误！

1.I've been to china for two years:i've been to 是一个非持续性短语，你不可以说“我盯唯曾经到过中国”这个状态持续两年.I've been in China for two years.我在中国待了两年了.
2.My friends in English sometime write to me: 我在英国举则磨的朋友有时候写信给我，in England;sometimes
3.ask me how long I'll Stay here. 省略主语时需用动名词开始asking
4.I enjoy meeting Chinese people and travel around ：traveling，同meeting一样为并列现在分词
5.My work is very interested：interesting,物做主语需要用词形容词
6.and there have so many things I don't know about:there be句型...不解释
7.and when I'm thinking returning home:现在来说这一句，唉...楼主是想说“并且问我现在想什么时候回英国”吧？and when to return home in my opinion now.
8.The answer of their questions: the answer for their questions

最后冒昧的正斗说问一句，楼主恐怕是初中生要写作文吧？完全是中国式英语语法...唉，我都改不下去了。建议多读读新概念英语哦！

改正在括号处标出，总烂态共十处错误！
