听力原文： When friends come to visit us in the evening, they spend their time telling us that they are in a hurry and looking at their watches. It isn't that our friends are all busy, it is just that we haven't got a television. People think that we are very strange. "But what do you do in the evenings？" they are always asking. The answer is simple. Both my wife and I have hobbies. We certainly don't spend our evenings staring at the walls. My wife enjoys cooking and painting and often attends evening classes in foreign language. This is particularly useful as we always go abroad for our holidays. I collect stamps and am always busy with my collection. Both of us enjoy listening to music and playing chess(象棋)together.
Sometimes there are power cuts and we have no electricity in the house. This does not worry us as we just light candles and carry on with what we were doing before. Our friends are lost--no television! --so they don't know what to do. On such evenings our house is very full as they all come to us. They all have a good time. Instead of sitting in silence in front of the television, everybody talks and plays games. Yes, life is possible without television!
