A new factory that turns used wine bottles into green sand could revolutionize the recycling industry and help to filter（过滤）the nation's drinking water.
For the last 100 years special high grade white sand quarried（开采）at Leighton Buzzard in Bedfordshire has been used to filter tap water to remove bacteria and impurities—but this may no longer be necessary.
The green sand has already been successfully tested by water companies and is being used in 50 swimming pools in Scotland to keep the water clean.
Backed by one million pounds from the European Union and the Department for Environment, Food and Rural Affairs(Defar),a company based in Scotland is building a factory to turn beverage bottles back into the sand from which they were made.
The idea is not only to avoid using up increasingly scarce sand in Scotland and avoid any further quarrying but also to solve a crisis in the recycles only 750 000 tones of it.
Howard Dryden, the scientist and managing director of the company has spent six years working on what he calls Active Filtration Meadia, or AFM, the recycled glass. He says he needs bottles that have already contained drinkable liquids to be sure that drinking water would not be polluted.
"The fact is that tests show that AFM does the job better than glass, it is easier to clean and reuse and has all sorts of properties that make it ideal for other applications, "he claimed. He also thinks the market will be able to take 250 000 tones of green sand a year. The plan is to build five or six factories in cites in UK where the bottles come from to cut down on transport.
The factory will be completed this month and is expected to go into full production on January 14 next year. Once it is providing a "regular" product, the government's drinking water inspectorate will be asked to perform tests and approve it for general use by water companies.

A.there is no need to keep water clean
B.A new factory has been set up
C.The green sand has been used to keep the water clean
D.White sand is being use up

4.The underlined word "Backed" in the third paragraph can best be replaced by"_____".
A. Allowed B. Opposed
C. Supported D. Forbidden
5.What would be the best title for the passage?
A. Revolution in the Recycling for the Industry.

C. Revolution in Environmental Protection.
D. Unlocking the Benefits of Green Sand.
You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the back of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can resist massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
1.What does the author say about the black box?
A. It ensures the normal functioning of an airplane.
B. The idea for its design comes from a comic book.
C. Its ability to resist disasters is incredible.
D. It is an indispensable device on an airplane.
2. What information could be found from the black box on the Yemeni airliner?
A. Data for analyzing the cause of the crash.
B. The total number of passengers on board.
C. The scene of the crash and extent of the damage.
D. Homing signals sent by the pilot before the crash.
3.Why was the black box redesigned in 1965?
A. New materials became available by that time.
B. Too much space was needed for its installation.
C. The early models often got damaged in the crash.
D. The early models didn't provide the needed data.
4. Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?
A. To distinguish them from the colour of the plane.
B. To caution people to handle them with care.
C. To make them easily identifiable.
D. To conform to international standards.
5.What do we know about the black boxes from Air France Flight 447?
A. There is still a good chance of their being recovered.
B. There is an urgent need for them to be reconstructed.
C. They have stopped sending homing signals.
D. They were destroyed somewhere near Brazil.
