Dear Peter,

     How about you study? It's Sunday today I'm writing a letter to you. I'm going to tell you. I'm going to

 tell you about things in Beijing.

     Beijing is different from London. In our country, we drive on the left side of the road, but here people

 drive on the right side. Most people go to work by bus or by bike. The rush hours (高峰时间) are from

 seven to nine in the morning and five to seven in the afternoon. People in China work around eight hours

 a day, five days a week. They usually begin to work at eight in the morning, and rest on Saturday and

 Sunday.

     I have Chinese classes every morning from Monday to Friday. The students in our class are from many 

 countries. We're all working hard and friendly. The Chinese students are ready to help us with our

 Chinese .We also help them a lot with their English. We're getting along very well (相处的融洽).

     That's all for today. Please write to me soon.

                                                                                                                            Yours,

                                                                                                                             Susan
