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 (潛水艇) 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 rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架艙). 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 (隔絕的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand(抵擋)massive force and temperatures up to 2,000℉. When submerged(潛入水中), 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.
小題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 ward off disasters is incredible.
D.It is an indispensable device on an airplane.
小題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.
小題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.
小題4: 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.

小題4:A最后一段Experts believe the boxes from Air France Flight 447, which crashed near Brazilon 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.文中提到,專(zhuān)家相信法航447號(hào)的黑匣子是在水下20000英尺的深度,接著指出,但是統(tǒng)計(jì)數(shù)據(jù)顯示他們?nèi)匀豢赡艹霈F(xiàn),即有可能被找到,接下來(lái)的具體統(tǒng)計(jì)數(shù)據(jù)也進(jìn)一步說(shuō)明了這一點(diǎn),所以答案為A。

Believing overweight among school children is the result of bake sales, the Education Department of New York declared that bake sales will be banned all through the states, as a part of their new “wellness”policy.
The ban gives a harder time to schools tying to earn money,because of budget difficulties. Bake sales have proven to be highly profitable toward schools with young people because the start-up costs are very small. Allie,a Roslyn High School freshman , agrees that bake sales are needed for school supplies.“l(fā) think it’s wrong for schools to ban bake sales because a lot of schools need the money to be raised. Our school could really use the money for new uniforms.”Allie also commented on the bake sales apparent cause of child overweight. “I feel that it is the student’s choice to eat the baked goods. lf they want it, let them have it.”Jessica,another Roslyn High School freshman, had a different opinion.“I feel that children can not always stay away from items such as cupcakes. It might be better if the amount of bake sales were limited, and only allowed students to buy one item.”
New York Education advisors are having trouble coming up with substitute product for students to sell. A plan of advertising healthier foods has come into play. However the department needs to consider if students will go for items like vegetables. Allie and Jessica don’t think so.“Students might not like the healthier foods. This way, the schools are gaining less money.”Allie shares. Another plan to think about is the idea of not selling food products altogether. Alternate programs are being conducted throughout New York schools,such as walk-a-thons, as a healthy way for students to earn money for their schools.
小題1:The new “wellness”policy is declared in order to_______.
A.help schools out of budget difficulties

BEIJING, July 8 (Xinhuanet)--- A new hotel concept has been realized in a village in Northern Sweden, which aims to make the simple treehouse become a world-class destination for travellers. The Treehotel, located in a place called Harads, will consist of four rooms when it opens on July 17th: the Cabin, the Blue Cone, the Nest, and the Mirrorcube.
Two additional rooms are scheduled to open in October. The long term vision(想象) is even more expansive. “Our goal in five years is to have 24 rooms from 24 different architects,” says Treehotel co-founder Kent Lindvall.
The first six rooms were designed by five different architects. The Mirrorcube which stands four meters high and four meters wide, and the walls of which are made with a mirrored glass, has drawn widespread attention as it will be attached to a single tree. “It’s an interesting building. You can’t find anything else like this in the world today. It’s unique(獨(dú)特的),” says Lindvall. “Everything will reflect in it---the trees, the birds, the clouds and the sun in the forest. So it could hardly be seen in the forest. This is untouched forest and we want to keep it the same way.”
Lindvall says the Treehotel’s vision proves a powerful draw, with enquiries(詢(xún)問(wèn)) coming in from far and wide. “I think what’s exciting here is that we’re just 60 km below the Arctic Circle. It means there’s a good possibility to have the northern lights in the winter and of course to have the midnight sun in the summer.”
The motto of the Treehotel is “Feel Free in a Tree” and expense will cost up to about $555.50 for two guests in the Cube, which is designed to hold up to four guests.
小題1:The underlined word “expansive” probably means _____.
A.costing a lot of money
B.covering a large area
C.requiring knowledge and skills

小題2:According to the passage, the Mirrorcube is a unique building because _____.
A.everything can reflect in it
B.it’s large with plenty of space
C.there is a large mirror wall in it
D.it has limited effect on local wildlife
小題3:Which of the following statements is TRUE?
A.The Treehotel is ideally situated to enjoy the natural wonders.
B.The Treehotel is a great base to explore the many local places of interest.
C.Travellers can have a relaxed holiday at a reasonable price in the Treehotel.

A man accused of failing to return more than 700 children’s books to five different libraries in the county was released from prison after a book publisher agreed to post his bond (保釋金) of $1,000. The publisher said, “There’s a story here. This is a man who loves books. He just can’t let go of them. He hasn’t stolen a single book. So what’s the crime? We think that Mr Barush has a story to tell. We plan to publish his story.”
When asked why he didn’t return the books, Mr Barush said, “Well, how could I? They became family to me.

He continued, “Books are people, too! They talk to you, they take care of you, and they enrich you with wisdom, humor and love. A book is a guest in my home. How could I kick it out? I repaired torn pages. I dusted them with a soft clean cloth. I turned their pages so they could breathe and get some fresh air.”
“Every week I reorganized them on their shelves so they could meet new friends. My books were HAPPY books. You could tell just by looking at them. Now they’re all back in the library, on the lower shelves, on the floors, at the mercy of all those runny-nosed kids. I can hear them calling me! I need to rescue them. Excuse me. I have to go now.”
