高中英語閱讀理解科技類 一

1、高中英語閱讀理解科技類 一Excused from recycling(回收利用) because you live in a high rise with a rubbish chute(垃圾道)? You wont be for long. Miamis 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

2、 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

3、 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 pho

4、ne when the box is full. And a particular piece of equipment breaks up the nonrecyclables Sorting(分類) 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

5、expensive that tons of recyclables remain wasted. Shantzis believes his system could help recycled materials become more cost-effective. 1The purpose in writing this text is _. Ato encourage people to recycle their rubbish Bto introduce a recycling system for high rises Cto describe the use of compu

6、ter technology in recycling Dto explain the need for rubbish collection in high rises 2When he says You wont be for long the writer means that _. Ayoull soon be living in a cleaner building Brubbish chutes will become out of date before long Cyou wont wait long for your turn to recycle rubbish Dit w

7、ont be long before youll have to recycle your rubbish 3Before dropping rubbish into the chute you have to _ Alock the other floors chute doors Bcheck if the container is full Cpress the correct button Dbreak up the rubbish 4.The biggest advantage of this new system is that _ Ait reduces the cost of

8、recycling Bit saves time and space Cit saves money for people living in high rises Dit 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

9、 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 worlds first large-scale deepwater wind turbine(渦輪發(fā)電機). Although it uses a fairly standard 152-ton, 2.3-megawa

10、tt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywinds creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the s

11、ea surface, will be tied to the ocean floor by three cable(纜索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywinds stability(穩(wěn)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

12、 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 its difficult enough to balance such a large tu

13、rbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spars to design a new kind of wind turbine, one whose gearbox(變速箱) sits at sea level rather than behind the blades (see picture )Hywind is a test run, but the benefits for perfecting floating wind-fa

14、rm 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 op

15、en up vast areas of the planets 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 stron

16、g 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 floor B. on the spar top C. at sea level D. behind the blades3.
