　　In 1901, H.G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers（探险者） landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the "moon people" they met. In turn, the "moon people" expressed their surprise. "Why," they asked, "are you traveling to outer space when you don't even use your inner space？"

　　H.G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the "moon people" asked is still an interesting one. A growing number of scientists are seriously thinking about it.

　　Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The "Chunnel", a tunnel（隧道）connecting England and France, is now complete.

　　But what about underground cities? Japan's Taisei Corporation is designing a network of underground systems, called "Alice Cities." The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome（太阳能穹顶）would cover the whole city.

　　Supporters of underground development say that building down rather than building up is a good way to use the earth's space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ "moon people" would agree. Would you？

56. The explorers in H. G. Wells’ story were surprised to find that the "moon people"____.

　　A. knew so much about the earth

　　B. understood their language

　　C. lived in so many underground cities

　　D. were ahead of them in space technology

57. What does the underlined word "it"（Paragraph 2）refer to？

　　A. Discovering the moon's inner space.

　　B. Using the earth's inner space.

　　C. Meeting the "Moon people" again.

　　D. Traveling to outer space.

58. What sort of underground systems are already here with us?

　　A. Offices, shopping areas, power stations.

　　B. Tunnels, car parks, shopping areas.

　　C. Gardens, car parks, power stations.

　　D. Tunnels, gardens, offices.

59. What would be the best title for the text？

　　A. Alice Cities-cities of the future

　　B. Space travel with H. G. Wells

　　C. Enjoy living underground

　　D. Building down, not up

China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
