假如你是刘宁，你的美国笔友Mike不善与人交谈，社交能力差，写邮件寻求你的帮助，请你给他回邮件，从使用身体语言的角度给他

Dear mark,
How are you recently?
I have got a solution to your problem with communication. You should improve your body language. I believe it can make a big difference to your social skills. First, keep smiling when you are with people. The friendly expression will make people feel closer to you. Second, keep eye contact to create a better communication with people around you. Third, when they are talking, don’t forget to nod once in a while to show that you are listening. At last, stand straight, keep your head up and relax your body. Those postures will make you look less nervous, and help you express yourself more confidently.
Best wishes!
Yours，
Liu Ning
