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 back 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 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.

閱讀下列短文,從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters(爬行生物) like to do the same thing!
Winter is the time when bugs (蟲子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.
Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.
They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.
They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.
56. What is the purpose of the first paragraph?
A. To point out that humans like to stay at home in winter.
B. To mean that humans and bugs have the same living habits.
C. To mean that bugs will invade the house for their winter.
D. To put forward the idea that bugs are not welcome in winter.
57. According to the text, what is diapause?
A. It is the same as the animals’ hibernation.
B. It often appears in warm areas all the year.
C. It is done to keep bugs active in winter.
D. It is a deep sleep similar to hibernation.
58. What often decides bugs’ diapause?
A. The lower local temperatures. B. The amounts of sunlight.
C. Kinds of environmental signals. D. The insects’ inside temperature.
59. According to the text, bugs invade humans’ homes to ______.
A. attack humans B. look for enough food
C. seek for protection D. show their evolutionary results
60. What would be the best title for the text?
A. Bugs’ life on cold wintry days
B. Why bugs invade your home in winter?
C. Good relations between humans and bugs
D. What does diapause mean?

D
KIDS in a Sudanese refugee camp raise a cloud of dust as they kick around a football. NBA superstar Traey Mc Grady watches from a distance before offering to buy the kids a grass patch for $1,000.
Perhaps he sees a Ronaldinho rising up out of the African soil. Or maybe he just wants to do something—anything—to give these children some hope. But he is told, politely, that grass is not what the kids need.
Mc Grady, 29, writes on his website that he traveled to Africa because he was tired of only reading about it in the news.“Who are the faces behind the statistics?” he said.“I need to see it for myself.” And he did. He stepped out of his beautiful house and flew to a place torn to bits by war and famine(饑荒). He slept in a tent. He talked with people who had suffered. And he swallowed his pride.
But no one should blame Mc Grady for wanting to buy the kids a patch of grass. Sport gave him a chance, so perhaps he thought it would do the same for the refugees.
Mc Grady was eyed by NBA scouts as a teenager and he didn’t bother going to college. Instead, he leaped right into the NBA. Since that move, basketball has given him a handsome living, but one very far removed from the lives of ordinary people. As Mc Grady would learn in Africa, most people see sport as just a break from life’s difficulties. They don’t mistake it for life itself. Only Mc Grady knows how the trip to Africa changed him, but I’d bet that, at the very least, it has given him a new sense for what is truly meaningful.
Mc Grady doesn’t own an NBA championship ring. He hasn’t risen to the heights of Kobe Bryant or Michael Jordan. But, perhaps, now he knows he doesn’t have to in order to truly make a difference in the world.
63.The refugee children most probably need______.
A.clean drinking water B.a grass football patch
C.necessities of survival D.a tent to sleep in
64.What can we learn about Mc Grady from the passage?
A.Basketball made him what he is today.
B.He is an NBA superstar as great as Kobe or Jordan.
C.He didn’t show his talent for basketball as a teenager.
D.He taught children to play football in a refugee camp.
65.What does the underlined part “scouts” in Paragraph 5 probably mean?
A.players. B.fans. C.audience. D.hunters.
66.Mc Grady learned from his visit to Africa that______.
A.he needn’t improve his basketball skills to reach the heights of his seniors
B.sport gave him a chance and means everything to him
C.people in hunger can never understand the importance of sport
D.what’s truly meaningful can be a world of difference to different people
