听力原文： Recent films, books, magazines and newspapers have reported about serious threats to the environment. Changes in climate, increasing pollution, rising energy demands, and decreasing supplies of water are worldwide problems. Designers and builders around the world are reacting to these environmental concerns with new conception of green house.
Green houses are designed to be sustainable. Something that is sustainable provides people today with what they need. But it does not use up or damage the natural resources.
Green houses use much less fossil fuels—oil, gas and coal—for energy. The houses are placed on the land so the sun warms them during cold months and is blocked during hot months. The houses have plenty of windows that open to let in cooling air. They have special equipment that uses a lot less water.
Green houses are made of wood from fast-growing trees so old growth forests do not have to be cut. They include recycled materials so something old is re-used, not thrown away as waste. The houses are healthier for people to live in. Materials used in them are not processed with strong chemicals that can produce harmful gases.
Houses that are environmentally friendly are not new. For years, architects in many areas of the world have designed and built them for environmental activists. But now, rapidly rising energy costs are increasing the demand worldwide for green houses that use less energy and other resources.

听力原文：M: Hello. Would you please tell me something about the stock？
W: Sure. What do you want me to start with？
M: Please start with the explanation of some terms like "a bull" and "a bear".
W: OK. A bull is a situation in which share prices are rising.
M: What about a bear then？
W: A bear is the situation in which share prices keep falling.
M: Oh, I see. But why the prices get rising or falling？
W: If there are more buyers, the price will rise. Otherwise, the price will be lower and lower.
M: How can we make money in the stock market？
W: If you believe the market will go up, you can buy in or hang on. If it turns out to be true, you can make your profit.
M: I heard that some people can earn money out of a bear market. How do they win in such a situation？
W: lf you believe the market will fall down, you can sell your shares and buy back at a lower price. The price difference is your profit.
M: It sounds easy to make money from stock investment.
W: Not at all. When you really invest in stock market, you'll get involved into the whole world.
M: What do you mean by that？
W: To decide which share you'll buy in is quite hard sometimes. You have to consider the market tendency, the growth of the company and you'd better know something about technical analysis.
M: So boring it is. I'd better invest in some fixed interest fields.
W: Certainly you can. You won't suffer from the risks. But your wallet will suffer.
M: What should I do？
W: If you really invest in stock, perhaps you should find a broker.
