Jenny and Li Ming watched Bob play basketball this evening. They arrived at the gym(体育馆)at 6：30. Bob's team played with the Orange Team. Everyone played hard! Jenny and Li Ming had fun at the gym. They yelled for Bob's team. Finally, Bob's team won. They were very happy.

Dear Li Fei,
    How are you? I will have a short holiday next week and have decided to visit Shanghai for a second time. I have booked a room in the Peace Hotel. I hear it is on the Bund(外滩) and has a good view of the famous Huangpu River. I will arrive on the night of March 27 and leave early on March 29. I would like to visit some of the most famous places, such as Nanjing Road and Yu Garden in Chenghuangmiao.
    Can you give me some suggestions for my visit to Shanghai? I will have only one day to look around Shanghai. I will be happy if you can make a tour plan for me. Please say hello to Lu Mei. I'm looking forward to your reply.  
Yours,
Sandy
