请您为我批改一篇英语作文！O(∩_∩)O谢谢！！！
Dear Andrew ,
Very happy to hear from you and you’re welcome to study in our school for the next two months .
As for to and from school ,I think riding a bicycle is not a bad choice .
Bicycle is a common-use vehicle,which is very popular among the students for it is environmentally-friendly ,and it can also build up your body .
In addition ,there are many things you must pay attention to. Firstly ,you shouldn’t race with other students when you are on the high-speed road ,it is very dangerous to you .Secondly ,riding with a low speed is a sane behavior .
hopefully ,what I’ve mentioned above could be helpful and wish you a fun time in our school .
Yours sincerely ,
Zhang Lin
