7、are trying to develop new ways of rescuing people from burning skyscrapers. One idea is a platform capable of flying vertically and hovering in the air like a helicopter. The platform would rise up and down alongside a skyscraper and pick up people trapped in high stories.The idea for the vertical t

8、akeoff platform was hatched more than ten years ago by a Russian aerospace engineer, David Metreveli, who has since moved to Israel. Metrevelis design, called the Eagle, calls for two jet engines that turn four large horizontal propellers. The spinning of the propellers generates the necessary lift,

9、 or upward force, to raise the platform. The more power is supplied to the propellers, the higher the platform rises. Moving the platform sideways involves applying differing amounts of power to each propeller.Helicopters are now used in some cases to get people out of burning buildings. Escape bask

10、ets slung from them dangle beside the building for people to climb into. Unfortunately, the baskets cannot reach every floor of a building because the ropes from which they hang become unstable beyond a certain length.So far, Metreveli has built a small-scale model of the Eagle to test his idea.

The brea

16、kthrough adds to a growing trend that is likely to eventually make Thomas Edisons bright invention obsolete. LEDs are already used in traffic lights, flashlights, and architectural lighting. They are flexible and operate less expensively than traditional lighting.2 Michael Bowers, a graduate student

17、2 at Vanderbilt University, was just trying to make really small quantum dots, which are crystals generally only a few nanometers big. Quantum dots contain anywhere from 100 to 1,000 electrons. Theyre easily excited bundles of energy, and the smaller they are, the more excited they get. Each dot in

18、Bowers particular batch was exceptionally small, containing only 33 or 34 pairs of atoms.3 When you shine a light on quantum dots or apply electricity to them, they react by producing their own light, normally a bright, vibrant color. But when Bowers shined a laser on his batch of dots, something un

19、expected happened. He was surprised when a white glow covered the table. The quantum dots were supposed to emit blue light, but instead they were giving off a beautiful white glow.4 Then Bowers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with th

20、e mix. The lumpy bulb wasnt pretty, but it produced white light similar to a regular light bulb.5 LEDs produce twice as much light as a regular 60 watt bulb and burn for over 50,000 hours. The Department of Energy estimates LED lighting could reduce U. S. energy consumption for lighting by 29 percen

21、t by 2025. LEDs dont emit heat, so theyre also more energy efficient. And theyre much harder to break.6 Quantum dot mixtures could be painted on just about anything and electrically excited to produce a rainbow of colors, including white. The main light source of the future will almost surely not be

But, for

26、the first time, theyve constructed a simple cloaking device that makes itself and something placed inside it invisible to microwaves.When a person “sees“ an object, his or her eye senses many different waves of visible light as they bounce off the object. The eye and brain then work together to orga

27、nize these sensations and reconstruct the objects original shape. So, to make an object invisible, scientists have to keep waves from bouncing off it. And they have to make sure the object casts no shadow. Otherwise, the absence of reflected light on one side would give the object away.Invisibility

28、isnt possible yet with waves of light that the human eye can see. But it is now possible with microwaves. Like visible light, microwaves are a form of radiant energy. They are part of the electromagnetic spectrum, which also includes radio waves, infrared light, ultraviolet rays, X rays, and gamma r

29、ays. The wavelengths of microwaves are shorter than those of radio waves but longer than those of visible light.The scientists new “invisibility device“ is the size of a drink coaster and shaped like a ring. The ring is made of a special material with unusual ability. When microwaves strike the ring

30、, very few bounce off it. Instead, they pass through the ring, which bends the waves all the way around until they reach the opposite side. The waves then return to their original paths.To a detector set up to receive microwaves on the other side of the ring, it looks as if the waves never changed t

31、heir paths - as if there were no object in the way ! So, the ring is effectively invisible.When the researchers put a small copper loop inside the ring, it, too, is nearly invisible. However, the cloaking device and anything inside it do cast a pale shadow. And the device works only for microwaves,

32、not for visible light or any kind of electromagnetic radiation. So, Harry Potters invisibility cloak doesnt have any real competition yet.（分数：15.00）(1).Harry Potter is mentioned in the passage, because scientists（分数：3.00）A.can now make an invisible cloak of the same kind as he uses.B.try to make an

33、invisible cloak of the same kind as he uses.C.try to invent a device similar in idea to the invisible cloak he uses.D.know that it is possible to make an invisible cloak of the same kind.(2).What is true of microwaves?（分数：3.00）A.Their wavelengths are shorter than those of visible light.B.Their wavel

34、engths are longer than those of visible light.C.They are different from visible light as they are a kind of radiant energy.D.They axe visible to the human eye.(3).What is NOT true of the invisibility device?（分数：3.00）A.It is made of a special material with unusual ability.B.Microwaves bounce off it w

35、hen they strike it.C.Microwaves pass through it when they strike it.D.It bends the microwaves all the way around until they reach the opposite side.(4).What does the word “coaster“ mean in the passage?（分数：3.00）A.A disk or plate placed under a drinking glass to protect a table top.B.A vessel engaged

36、in coastal trade.C.A roller coaster.D.A resident of a coastal area.(5).Harry Potters invisibility cloak doesnt have any real competition yet, because（分数：3.00）A.scientists have not found out how his cloak works.B.the cloaking device is a total failure.C.the cloaking device works only for microwaves.D

37、.the cloaking device works only for visible light.B第二篇/BBJapanese Car Keeps Watch for Drunk Drivers/BA concept car developed by Japanese Company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over-tired drivers off the road.The cars sensors check

38、odors inside the car and monitor a drivers sweat for traces of alcohol. An in-car computer system can issue an alert or even leek up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed firmly and deeply in the driver and passenger seats, while a detector in the gea

39、r-shift knob measures perspiration from the drivers palm.Other carmakers have developed similar detection systems. For example, Swedens Volvo has developed a breathalyzer attached to a cars seat belt that drivers must blow into before the engine will start.Nissans new concept vehicle also includes a

40、 dashboard-mounted camera that tracks a drivers alertness by monitoring theft eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest.The car technology is still in development, but general manager Kazuhiro Doi says the

41、combination of different detection systems should improve the overall effectiveness of the technology. “For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used,“ Doi says. Nissan has no specific timetable for

42、 marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.The cars seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that s

43、ome of the technology, such as the alcohol odor sensor, should be improved. “If you drink one beer, its going to register, so we need to study whats the appropriate level for the system to activate,“ he says.In the UK, some research groups are using similar advanced techniques to understand driver b

44、ehavior and the effectiveness of different road designs.（分数：15.00）(1).Which of the following statements is NOT true of the Japanese concept car?（分数：3.00）A.It has a sensor system that could issue a warning if the driver is drank.B.It has sensors that detect traces of alcohol inside the car.C.It has s

45、ensors locked up in the ignition system.D.It has a breathalyzer-like detection system.(2).What has Volvo developed?（分数：3.00）A.The same detection system mentioned in the previous paragraph.B.A breathalyzer attached to a cars seat belt.C.A smart car seat belt.D.An intelligent engine.(3).What is the fu
