Ladies and gentlemen,
Welcome to our class and welcome to our evening party. First of all, let me say a few words about our class. There are 50 students in our class-26 of us are boys and 24 are girls. Most of us are from Beijing. We are mostly at the same age-about 17. Some go in for sports, and some are interested in reading,. We have 6 subjects in all, including English, Chinese and mathematics. All of us like to study English, and we usually spend a lot of time on it.
In our program tonight, there will be a short play, group singing and so on. I hope you will enjoy them and haove a good time. Thank you.
