高中英语阅读理解科技类一Excused from recycling(回收利用) because you live in a high rise with a rubbish chute(垃圾道)? You won't be for long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too .In Shantzis' Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal, and other rubbish to go into separate boxes.The system is controlled from a board next to the chute door. The board has a button for each class of recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other floors' chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables Sorting(分类) recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted. Shantzis believes his system could help recycled materials become more cost-effective.1．The purpose in writing this text is _________.A．to encourage people to recycle their rubbishB．to introduce a recycling system for high risesC．to describe the use of computer technology in recyclingD．to explain the need for rubbish collection in high rises2．When he says "You won't be for long" the writer means that _______.A．you'll soon be living in a cleaner buildingB．rubbish chutes will become out of date before longC．you won't wait long for your turn to recycle rubbishD．it won't be long before you'll have to recycle your rubbish3．Before dropping rubbish into the chute you have to ___________A．lock the other floors' chute doors B．check if the container is fullC．press the correct button D．break up the rubbish4.．The biggest advantage of this new system is that _________A．it reduces the cost of recycling B．it saves time and spaceC．it saves money for people living in high risesD．it makes better use of the existing recovery equipmentBAccording to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills (see picture) to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.The project, called Hywind, is the world’s first large-scale deepwater wind turbine(涡轮发电机). Although it uses a fairly standard 152-ton, 2.3-megawattturbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable(缆索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind’s stability(稳定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the wh ole spar’s to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades (see picture )Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.1. The Hywind project uses totally new technology to ensure the stability of _______.A. the cables which tie the spar to the ocean floorB. the spar which is floating in deep-sea waterC. the blades driven by strong and steady sea windD. the stones filled in the spar below the sea surface2. To balance a bigger turbine high on a flatting spar, a new type of turbine is to be designed with its gearbox sitting ____________.A. on the sea floorB. on the spar topC. at sea levelD. behind the blades3. Wide applications of deepwater wind power technology can ____________.A. solve the technical problems of deepwater windmillsB. make financial profits by producing more turbinesC. settle the arguments about environmental problemsD. explore low-carbon power resources available at seaB DC A BCD。
