The system, called Driver Alert, aims to reduce deadly road accidents by 20%40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue. Driver Alert is based on a computerized wristband. The device, worn by drives or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel(方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the drivers response. Tiredness is directly related to a drivers response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy. In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the drivers response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible. The device has been delivered to the departments laboratories for testing. If these tests, scheduled for six months time, are successful, the makers will bring the product to market within about a year.1. According to the text, Driver Alert _.

She greeted me by name and started talking with great enthusiasm. Every now and then she stopped to smile at me or blow a kiss. She was reading to me an e-mail from my brother, and a lot of it was about his getting the phone company to give him a high-speed Internet connection. It was pretty cool.Rachel was there thanks to a new technology called Facemail. Facemail lets you send e-mail that gets ready to the receiver by an attractive male or female form or by a clown(小丑). The software, which is free, can be downloaded at www. F.Facemail faces are lifelike, and they simulate(模拟) emotions based on emotions that you put in your text. For example, type in-X, and Rachel blows a kiss.LifeFX, the company that develops the Facemail, is sure there are broad business uses.

British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces-which they think is a sure sign of intelligence.Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else, Kendrick said in an interview.So hours of seemingly mindless eating grass may not be so mindless after all.Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much individuality and are frightened of just about everything.All animals, including humans, once they are frightened dont tend to show signs of intelligent action, he explained.In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time, said Kendrick. It is a very strange system. They are showing similar abilities in many ways to humans. 13. From the first paragraph we can find that _. A. people used to think sheep are smarter than the other animals B. people used to raise sheep in a wrong way C. people dont consider sheep as clever animals D. people have done a lot of research on sheep14. From what Kendrick said in the interview we learn that _. A. scientists have learned a lot about sheeps intelligence B. scientists have learned little about sheeps intelligence C. scientists cant do anything more about sheeps memory D. scientists dont have to research animals memory15. As is shown in the passage _. A. sheep are among the weak animals B. it is not right for people to raise sheep in groups C. when sheep eat grass in the fields their minds may be active D. if people feel frightened, they may become more brave16. When scientists found that sheep show similar abilities in many ways to humans they may think it _. A. worrying B. moving C. frightening D. interesting E难度： 中 字数：286 words 标准用时：5 minutes 实际用时：_Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a citys reusable waste.17. The most suitable title for this passage would be _. A. Places for Disposing Waste B. Waste Pollution Dangers C. Ways of Getting Rid of Waste D. Waste Disposal Problem18. During the 18th century, people disposed their waste in many ways EXCEPT for _. A. burying it B. recycling it C. burning it D. throwing it into rivers19. What can be inferred from the fourth paragraph? A. Farm areas accept waste from the city in modern society. B. There is cheap land to bury waste in modem society. C. It is difficult to find space to bury waste in modem society. D. Ways to deal with waste in modem society stay the same.20. The main purpose of writing this article is to _. A. draw peoples attention to waste management B. warn people of the pollution dangers we are facing C. call on people to take part in recycling programs D. tell people a better way to get rid of the wasteUnit 1科技环保类 A1.
