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.小题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. |
| 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. |
| 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. |
| 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. |
| 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. |

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.
小题1: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 |
| 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 |
| 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 |
| A．Allowed | B．Opposed |
| C．Supported | D．Forbidden |
| 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. |

There is a small shop about 200 meters from where I live that sells groceries, meat and other basic necessities. About 10 yearsa ago, there was a beggar who would go into the shop every day and ask the owner for a 21 . The owner, 22 he would love to help, simply didn’t have any jobs availabe, so he kept 23 the man’s office.
This situation continued 24 for a few months, until the owner 25 to give the homeless man a job which 26 sweeping outside the shop. Every single day form 5 a.m, the homeless man was there doing the very 27 he could for the 28 , making it the community’s favourite, even though it did earn him pennies. 29 , the owner saw how good a job the man was doing and gave him a job working 30 a cashier(收银员). He was watched closely to make sure that he didn’t 31 any of the money received from the sales. He was still homeless, after all. The homeless man did a/an 32 job as a cashier for over 2 years, and did such a good job that he was promoted to 33 the finances for the whole shop.
To my 34 , this was the arrangements up until 2 years ago, when the owner 35 . In his will, he only had one 36 , to give the whole shop to the now stable, “homeless” man.

million TV viewers. TV can make anything or anyone well-known overnight.
This is the principle behind “quiz” or “game” shows, which put ordinary people on TV to play a game for prizes and money. A quiz show can make anyone a star, and it can give away thousands of dollars. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show’s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn’t like the person who won the game, they turned the show off. The result of this cheating was a huge scandal(丑闻). Based on the show off, a movie titled “Quiz Show” is on 40 years later.
Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren’t taken seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating(羞辱) them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions.
小题1:What is the most important thing as to television?
| A．How many viewers they can attract | B．Becoming the best seller on the list |
| C．How much money can be given away | D．The number of people attending shows |
| A．Planning the shows with effort | B．Drawing the curtain on the stage |
| C．Controlling the result secretly | D．Playing “quiz” or “game” openly |
| A．he had earned enough wealth and fame. |
| B．one of the participants had told the truth |
| C．the film “Quiz Show” was being shown |
| D．his frequent appearance had bored the audience |
| A．TV Game Shows are more popular than before. |
| B．the scandal was not made known until 40 years later |
| C．getting money is the only purpose of people taking part in shows |
| D．people can make themselves famous by taking part in shows |
It was funny watching him, because his clothes remained the same in size. They simply piled up around him so that he looked like a small boy in his father’s clothes. But he kept getting smaller and smaller. As my colleague Dawson and I watched him, he disappeared! All we could see was Finchley’s clothes on the floor. They looked so strange, because the lab coat was on top, shirt and trousers inside and, I suppose, underclothes inside again. It gave me a strange feeling, and I think Dawson was a bit shaken, too.
Dawson was sitting on his chair in front of a microscope he’d been using to examine a family of mites(螨虫). He looked through the scope kind of absently again, and was nearly scared to lose awareness when he found old Finchley waving back from the other end.
It seems as if Finchley had taken a free ride on a dust mite and landed on the land of the mite family. Of course, we didn’t know till Finchley told us later. But anyhow, as I said, Dawson nearly passed out. He jumped off his chair and pointed at the microscope, to shocked to speak.
小题1:Finchley disappeared because ________.
| A．he took something poisonous |
| B．he was changed into a dust mite |
| C．his father’s clothes totally covered him up |
| D．what he and his colleagues invented resulted in his disappearace |
| A．got into his scope by accident | B．was waving through his telescope |
| C．suddenly got lost in his clothes | D．gradually disappeared in the lab |
| A．some kind of medicine | B．a new powerful microscope |
| C．a machine to make people small | D．a new way to make a culture of mite |
| A．passed out there and then | B．is not fit to be a scientist |
| C．is a devoted scientist | D．will remain tiny all the time |
Her popularity doesn’t end there. The BBC reports that the University of South Carolina has a sociology course about the life, work and rise to fame of Lady Gaga. The course is due to start in spring 2011. “We’re going to look at Lady Gaga as a social event,” said professor Mathieu, who will teach Lady Gaga and the Sociology of Fame.
Germanotta, in fact, is a college student. She learned to play the piano by age 4. At age 17, she was one of the only 20 young people to get early admission to New York University’s Tisch School of the Arts, the famous music school. Yet after her second semester, she took a big risk—she decided to quit and concentrate on a music career. But hwo did she manage to go from nowhere to supar star in just two years?
She may well have had a plan for the top. She created “The Ultimate Pop Burlesque Show” with another artist. It was the first of many strange images. The pair gained enough attention to get a spot at a famous music festival in Chicago. Later, a record company signed Germanotta.
While Lady Gaga enjoys popularity, there are critics accusing her of regularly using rude language in her lyrics(歌词) and wearing overly sexy clothing.
