大学英语阅读理解

  第一篇:

  You never see them, but they're with you every time you fly. They record where you're 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 the Comoros Islands in the Indian 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 model for a black box, which became a requirement on all US 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 (起落架舱). That 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 quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2 000°F. 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.

  57. 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.

  58. 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.

  59. 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.

  60. Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?

  A) To distinguish them from the color of the plane.

  B) To caution people to handle them with care.

  C) To make them easily identifiable.

  D) To conform to international standards.

  61. 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 restructured.

  C) They have stopped sending homing signals.

  D) They were destroyed somewhere near Brazil.

  第二篇:

  As you are probably aware, the latest job markets news isn’t good: Unemployment is still more than 9 percent, and new job growth has fallen close to zero. That’s bad for the economy, of course. And it may be especially discouraging if you happen to be looking for a job or hoping to change careers right now. But it actually shouldn’t matter to you nearly as much as you think.

  That’s because job growth numbers don’t matter to job hunters as much as job turnover data. After all, existing jobs open up every day due to promotions, resignations, terminations, and retirements. (Yes, people are retiring even in this economy.) In both good times and bad, turnover creates more openings than economic growth does. Even in June of 2007, when the economy was still humming along, job growth was only 132,000, while turnover was 4.7 million!

  And as it turns out, even today — with job growth near zero — over 4 million job hunters are being hired every month.

  I don’t mean to imply that overall job growth doesn’t have an impact on one’s ability to land a job. It’s true that if total employment were higher, it would mean more jobs for all of us to choose from (and compete for). And it’s true that there are currently more people applying for each available job opening, regardless of whether it’s a new one or not.

  But what often distinguishes those who land jobs from those who don’t is their ability to stay motivated. They’re willing to do the hard work of identifying their valuable skills; be creative about where and how to look; learn how to present themselves to potential employers; and keep going, even after repeated rejections. The Bureau of Labor Statistics data shows that 2.7 million people who wanted and were available for work hadn’t looked within the last four weeks and were no longer even classified as unemployed.

  So don’t let the headlines fool you into giving up. Four million people get hired every month in the U.S. You can be one of them.

  57. The author tends to believe that high unemployment rate ______?

  A) deprives many people of job opportunities.

  B) prevents many people from changing careers.

  C) should not stop people from looking for a job.

  D) does not mean the U.S. economy is worsening.
