Many students in our school come from big cities. They bring the high-tech things to school, for example, mobile phones, MP3 players, CD players and electronic dictionaries. They show off these things to others. What about your classmates in the US? Do they have the same things? Li Hong From: jenny@compail.ca To: Li-Hong @ net.cn Subject: Repeat! Date: 01/09 8:00 p.m. Dear Li Hong, We also bring these high-tech things when we are back to school. However, we often work during the holidays, and make money to buy these things. I think we need these things. We need mobile phones to contact with our friends. We also need CD players to listen to music. Electronic dictionaries can be useful for our study too. Jenny
