Section C
In many countries, people produce power from coal, but it is very dirty and causes acid rain. Some countries use nuclear energy to produce power. However, nuclear power can be very dangerous. To solve the energy problem, people all over the world are looking for new ways to produce power.
China is one of the first countries in the world to use biogas technology. Farmers recycle straw, grass and animal waste to make biogas. This renewable energy is used in people’s everyday lives. Its key disadvantage is that the process requires a long time (up to 30 days) and the cost is high.
Electric vehicles were developed in the 1990s. On April 11, 2010, a new kind of vehicle named “Yezi” was shown in the 2010 Shanghai World Expo. It produces electricity from the sun, the wind and CO2. It can not only protect the environment but also save energy. It’s too small to hold many people, but larger models will be developed in the near future.
In China, the best-known maglev train is the German-built one in Shanghai. It takes people just 7 minutes to go to the airport 30 km away. The train can reach a top speed of 431 km per hour. It is quiet and quick. There is no wheel noise, because there are no wheels. Maglev trains are very energy-efficient and do not pollute the air. However, maglev guide paths are much more expensive than traditional steel railways.
在许多国家，人们用煤来生产动力，但是这种方法很脏并且会导致酸雨。一些国家使用核能源来生产动力，然而，核能却非常危险。为了解决能源问题，全世界的人们都在寻找新的方法来生产动力。
中国是世界上最早使用生物技术的国家之一。农民们回收麦杆、草和动物粪便来制作生物气，这种可再生能源被应用到人们每题的生活当中去。它的主要缺点是这个过程很长（长达30天），并且建设费用高。
电动车辆是在20世纪90年代被发明的。2010年4月11日，一种新型的电动车“叶子”在上海世博会上展出。它通过太阳、风和二氧化碳发电。它不仅环保，而且节约能源。它太小，不能承载太多的人，但是，在不久的将来，更大的车型将会被研制出来。
在中国，最有名的磁悬浮列车由德国建造，在上海投入使用的那辆。仅用7分钟这辆车就可以将人们送30千米以外的机场。这辆车最高速度可达431千米，它安静并且快速。它不会产生车轮的噪音，因为它根本没有车轮。磁悬浮列车能够有效利用能源而且不会污染空气。然而，悬浮轨道的建设费用却远远高于传统铁轨的建设费用。
