参考答案：Dear Linda,
I know it’s hard to start a new life in a strange city.However, just staying at home doing nothing but surf the Internet is not good for you.You’d better go out and join in some social activities.By doing this, you can get to know more people around.And it would be a good idea to help others if possible and show them you are open and friendly as well.
With time going on, people will know you better and like to make friends with you.
Best wishes!
Yours,
Li Hua
