I'm Li Hua, the monitor of Class One Grade Eleven.
I ' m very excited about your coming to our school next term as an exchange student.
Firstly, I'd like to tell you about the weather in my city, which is often windy and cold in winter. So you should bring your warm clothes. Secondly, would you mind eating noodles? Because people here mainly live on wheat flour. However, don't worry about it. You will have no difficulty in finding western food. Thirdly, I want to introduce our class to you. The teachers in our school are not only experienced and knowledgeable, but also patient and understanding. Everyone in my class is active. I hope you will soon become a member of our Class.
l'm looking forward to your coming.
