Dear Tom:
I‘m now studing in Shan Dong College Of Tourism & Hospitality .We have less lessons compare to high school life,but the pressure didnt decrease,because lessons are much harder than before,and there are only 4 years for my to enter the community,which means i will have bigger responsibilities.
Teachers and classmates are very friendly to me,that made me feel better from homesickness.and i found that Cambridge is a warm community.I have volunteered to the community and will spend 2 hours every week volunteering.
It is really fun,because i can develop myself!by the way,i would like to invite you to spend the X-mas with me,we can hang out and play for the whole holiday,enjoying the snow view.Hope you can reply soon~
yours
