Let's look at how a new car is created. First, several 1 talk about the new car and any good ideas that they have. Then they sit down at their computers and 2 many sketches（素描）．The best two or three drawings are chosen and then more detailed drawings of 3 are developed on the computer. You can change the size, shape or colour of any part on the computer to see 4 the car would look and then you can choose the best design. Both the inside and the outside of the car have to be designed. Part of the inside of the car is 5 so that the designers can sit in it. They can feel if there is enough 6 inside and if they can reach 7 Then some cars are built-there are more than 15, 000 parts of a car to 8 When everything is known to be 9 the cars are made in the factory. Again computers are used to make sure that all the parts are 10 as they are needed. The factory usually stays open all through the night so that the car production never stops. 1．A．drivers B．designers C．workers D．salesmen 2．A．draw B．order C．type D．enjoy 3．A．bicycles B．trains C．cars D．buses 4．A．how B．if C．what D．that 5．A．covered B．painted C．locked D．built 6．A．metal B．glass C．leather D．room 7．A．nothing B．somebody C．everything D．nobody 8．A．choose B．test C．show D．repair 9．A．safe B．easy C．cheap D．fast 10．A．rare B．electronic C．comfortable D．ready 二、阅读单选 Have you ever seen a solar panel（太阳能电池板）in your neighbourhood Solar panels take energy from the sun and turn it into electricity. Over the past ten years, the price of solar panels has gone down greatly. In many parts of the world, solar energy is now the cheapest form of electricity. More and more people have started using solar energy to power their homes. However, solar panels also have their problems. They stop working at night and on rainy days. Is it possible to make them produce electricity all of the time Scientists at Suzhou University, China, have invented a new solar panel now. It can produce electricity not only from solar energy but also from falling rain. When a raindrop falls on the solar panel and then rolls（滚动）down, it creates friction（摩擦力）on the surface of the panel, which can then be turned into electricity. Sun Baoquan is one of the inventors. “Our new invention can produce electricity in any weather during the day,”he says. “It can even provide electricity at night if there is rain. ” The solar panel, however, does not make much electricity from falling rain. So Sun Baoquan is still working hard to improve it. The scientist also wants to make more flexible solar panels, which are as soft as clothing. They will be much lighter and provide more electricity. The field of solar energy ... ...
