“Sky Whale” is a plane with four engines that can carry over 700 people. The airplane will exist for short distances between cities. The technology will use eco-engines with energy recovery systems which are able to feed back to the planes themselves. With a capacity to transport a large number of passengers, like a train of high speed, “Sky Whale” will be a safer type of planes for the future use. We will also have supersonic planes which are transcontinental or transoceanic. They can fly at a very high altitudes more than 30,000 meters and at record speeds. The engines which can change according to the situations are called intelligent engines. |

Read the text and write T(true) or F(false):
Many people still believe that natural resources will never be used up. Actually, the world’s energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power is the only alternative. However, many people do not approve of using nuclear power because it’s very dangerous. What would happen if there was a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations. The most effective thing is that we should use natural resources as economical as possible. |
