假如你是李华，你的美国朋友Jack准备来中国学习，因此想了解一些中国人的肢体语言。请你用英语给他写封邮件，向他介绍一些日常的肢体语言（如：见面时、表达支持反对、赞美或感激等时候的肢体语言）。
注意：
词数100左右；可以适当增加细节，以使行文连贯。

【答案】Dear Jack，
I am glad to receive your email.In China，we wave our hands to say "hello"or "good-bye"".We usually greet our guests by shaking hands with them.Some people may nod and smile instead of shaking hands.When you are introduced to a Chinese group，they may greet you by clapping their hands.Like in many countries，we nod our heads to say "yes"and shake our heads to say "no".People will hold their thumbs up to praise a person if he does something great.Sometimes，we bow to show great respect and thanks to others.
I hope this information will be helpful to you.
Yours，
Li Hua
