COOL INVENTIONS
From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进) around the neighborhood has never been better.
Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle.
You're having a blast at your friend's birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.According to the passage, the Venturi Eclectic .

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.It may no longer be necessary to use high-grade white sand to keep water clean because_____.
| 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 |
According to the passage ,the new idea can do the following except_____.
| A．avoiding using up increasingly scarce sand |
| B．avoiding further quarrying of white sand |
| C．solving the crisis in the recycling industry |
| D．cutting down the cost on transport |
Tests show that ______ in keeping the water clean.
| A．AFM is more efficient than white sand |
| B．AFM is more efficient than glass |
| C．glass is more efficient than AFM |
| D．white sand is more efficient than green sand |
The underlined word "Backed" in the third paragraph can best be replaced by"_____".
| A．Allowed | B．Opposed |
| C．Supported | D．Forbidden |
What would be the best title for the passage?
| A．Revolution in the Recycling for the Industry. |
| B．Modern Technology an New Markets. |
| 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 wel
ls (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 stainle
ss 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.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. |
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. |
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. |
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. |
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. |

Japanese people,who never miss a chance to be photographed,were lining up to get their pictures on a postage stamp．Vanity（虚荣）stamps with personal photographs went on sale for the first time in Japan as part of an international postage stamp exhibition．The customer’s photo was taken with a digital camera and then printed on stamp sheets,a process that takes about five minutes．Sold in a sheet of 10 stamps for $8．80,little more than the cost of lunch in Tokyo,each stamp printed a different scene from a traditional painting along with the photo．
The stamps can be used normally to mail a letter,and postal officials hope they will help encourage interest in letter writing in the Internet age．“Certainly e-mail is a useful method of communication,but letters are fun in a different way,”said Hatsumi Shimizu an official in the Post Ministry．“We want to show young people that letters can be fun too．”
While similar stamp sheets appeared in Australia in 1999 and are now sold in some nations and territories,Japan’s fondness for commemorative photos is likely to make them especially popular here．Indeed,officials had prepared 1 000 sheets but they were sold out in less than 30 minutes．Although the stamps are currently only available as a special service during the exhibition,postal officials said they may start selling them on a regular basis in the future．The best title of this passage might be______．
| A．Never Miss a Chance to be Photographed | B．Your Own Face on a Postage Stamp |
| C．First Japanese Postage Stamps with a Photo | D．Letters are as Fun as E-mails |
By saying“little more than the cost of lunch in Tokyo”,the author really means______．
| A．this service is not very expensive | B．the cost of this service is very high |
| C．food in Tokyo is very dear | D．$8．80 is a very small amount of money |
The purpose of this activity is______．
| A．to make the international postage stamp exhibition more interesting | |
| B．to make more stamps for normal use | C．to draw interest in writing letters |
| D．to satisfy Japan’s fondness of commemorative photos |
Which of the following is true according to the passage?
| A．Japanese people like to take photos． | B．This kind of stamps must be used to mail letters． |
| C．Japanese people can get this kind of stamps easily after the stamp exhibition． | |
| D．This service is more popular in Japan than in other places． |
If women are mercilessly exploited（剥削） year after year, they have only themselves to blame．Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores．Clothes wh
ich have been worn only a few times have to be put aside because of the change of fashion．
Changing fashions are nothing more than the intentional creation of waste．Many women spend large sums of money each year to replace clothes that have hardly been worn．Women who cannot afford to throw away clothing in this way, waste hours of their time changing their old-fashioned dresses．Skirts are lengthened or shortened; neck-lines are lowered or raised, and so on．
No one can claim that the fashion industry contributes anything really important to society．Fashion designers are rarely concerned with necessary things like warmth, comfort and durability （耐用）．They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look right．There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or picking her way through deep snow in high heeled shoes．
When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious．Do the constantly changing fashions of women's clothes, one wonders, reflect basic qualities of inconstancy and instability? Men are too clever to let themselves be cheated by fashion designers．Do their unchanging styles of dress reflect basic qualities of stability and reliability? That is for you to decide．Designers and big stores always make money_________．
| A．by mercilessly exploiting women workers in the clothing industry |
| B．because they are capable of predicting new fashions |
| C．by constantly changing the fashions in women's clothing |
| D．because they attach great importance to quality in women's clothing |
To the writer, the fact that women change their old-fashioned dresses is seen as ___________．
| A．a waste of money | B．a waste of time |
| C．an expression of taste | D．an expression of creativity |
New fashions in clothing are created for ___________．
| A．the commercial exploitation of women | B．the women's strength of character |
C．basic qualities of i nconstancy and instability |
D．an important contribution to society |
By saying "the conclusions to be drawn are obvious" （ Line One to Line Two, Paragraph Four）, the writer means that ___________．
| A．women's inconstancy in their choice of clothing is often laughed at |
| B．women are better able to put up with discomfort |
| C．men are also exploited greatly by fashion designers |
D．men are more reasonable in the matter of fashion |
