                                                                        A letter

Dear Li Ting,

     My new school is very nice. There are 50 students in my class. Two girls are America. But they can speak

Chinese very well. Their fathers work in our city. Billy is an English boy. He comes from London. He can speak little Chinese. They like China very much. They also like our Chinese food. They are very friendly. How many

Chinese students are there in our class? How many Young Pioneers are there in our class? Can you guess?

Please write soon!

                                                                                                                              Love from

                                                                                                                                Liu Tan
