　　Hi Amy

　　I hope you are doing fine at school.

　　Today is my second day in Shanghai. (1)________ I had breakfast at the hotel coffee shop in the morning, I went to the office. I did not know they had so many problems (2)________ I spoke to the clerks there. They told me that they took some computer courses (3)________ they started to use computers in the office but they still could not use them well. You are really lucky, Amy. You have the chance to learn about computers (4)________ you start working in society.

　　(5)________ I had visited the Shanghai office, we went to the Oriental Pearl Radio and TV Tower, I did not know how tall it is (6)________ I saw it myself. I bought some souvenirs there (7)________ I left. I think you will like them. (8)________ I finish, I must remind you to record my TV programmes. When I come back, I will watch all of them (9)________ I go to bed.

　　Dad
