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.

A. There is still a good chance of their being recovered.
B. There is an urgent need for them to be reconstructed.

Self-confidence is an attitude which allows individuals to have positive yet realistic views of themselves and their situations. Self-confident people trust their own abilities, have a general sense of control in their lives, and believe that,within reason, they will be able to do what they wish., plan., and expect. Having self-confidence does not mean that individuals will be able to do everything. Self-confident people have expectations that are realistic. Even when some of their expectations are not met,they continue to be positive and to accept themselves.
People who are not self-confident depend too much on the approval of others in order to feel good about themselves. They tend to avoid taking risks because they fear failure. They generally do not expect to be successful. They often put themselves down and tend to ignore compliments(贊美)paid to them By contrast,self-confident people are willing to risk the disapproval of others because they generally trust their own abilities. They tend to accept themselves;they don't feel they have to conform in order to be accepted.
Many factors affect the development of self-confidence. Parents' attitudes are crucial to children's feelings about themselves,particularly in children's early years. When parents pro- vide acceptance, children receive a solid foundation for good feelings about themselves. If one or both parents are much to critical or demanding, or if they are overprotective and discourage children's moves toward independence, children may come to believe they are unqualified or inadequate.
Surprisingly, lack of self-confidence is not necessarily related to lack of ability. Instead it is often the result of focusing too much on the unrealistic expectations or standards of others, especially parents and society. Friends' influences can be as powerful or more powerful than those of parents and society in shaping feelings of one's self. Students in their college years reexamine values and develop their own identities and thus are particularly sensitive to the influence of friends.

Your peers are people your age or close to it who have experiences and interests similar to yours. You and your friends make dozens of decisions every day, and you influence each other’s choices and behavior. This is often ________ --- it’s human nature to listen to and learn from other people in your age group.
Sometimes, though, the stresses in your life can actually come from your peers. They may pressure you into doing something you’re uncomfortable with, such as shoplifting, doing drugs or drinking, or taking dangerous risks when driving a car.
The pressure to conform(隨潮流) can be powerful and hard to resist. A person might feel pressure to do something just because others are doing it. Peer pressure can influence a person to do something that is relatively harmless--- or something that has more serious consequences.
People may feel pressure to conform, so they fit in or are accepted, or so they don’t feel awkward or uncomfortable. When people are unsure of what to do in a social situation, they naturally look to others for cues(暗示)about what is and isn’t acceptable.
The people who are most easily influenced will follow someone else’s lead first. Then others may go along, too --- so it can be easy to think, “It must be OK. Everyone else is doing it. They must know what they’re doing.” Before you know it, many people are going along with the crowd --- perhaps on something they might not otherwise do.
Responding to peer pressure is part of human nature --- but some people are more likely to give in, and others are better able to resist and stand their ground.
It’s not always easy to resist negative peer pressure. But when you do, it is easy to feel good about it afterwards. And you may even be a positive influence on your peers who feel the same way --- often it just takes one person to speak out or take a different action to change a situation.

So there are four of them in this car heading north from Coleman in the heart of Texas to the town of Abilene (阿比林), some 53 miles away. It is a hot day, and the drive is dusty and boring. Someone has had the bright idea to interrupt a nice family game of dominoes (多米諾) to go on a four-hour round-trip to eat at a really not very good restaurant.
When they are back home again, one family member admits that she hasn’t enjoyed herself all that much. One by one they all confess that they would rather have stayed at home. “I only went along with it because I thought the rest of you wanted to go,” says everyone. No one wanted to go to Abilene. It had just happened.
This story was first told by Professor Jerry Harvey in an article published in 1974 called The Abilene Paradox (悖論) and other meditations on management. It offers a wonderful insight into the way that decisions can sometimes just emerge, without ever being consciously “made”.
Whether they mean to or not, groups exert a pressure to conform (順從). A senior management team can find itself a long way down the track to a bad decision without realizing that the idea has very little support around the table.
Close-knit (組織嚴(yán)密的) teams are easily influenced by the pull of groupthink. The late Professor Janis suggested several ways in which teams can avoid it. Two key steps are to invite experts from outside into meetings, and to appoint at least one person to the role of “devil’s advocate” — a role that should be played by different people in different meetings.
