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.

About 90 percent of Chinese believe the polarization(分化) between the rich and poor is “serious” in China, according to a survey conducted by China Youth Daily. And more than 80 percent of the respondents(對象) surveyed said something must be done to narrow the expanding gap between the rich and poor, while 14.1 percent said it was necessary.
The polarization has aroused wide concern among the public in recent years. The State Development and Reform Commission(國家發(fā)改委) said the Gini Coefficient had reached 0.47 for China, up from o.29 two decades ago. Usually, a country with a number above 0.4 is warned to pay attention to the income inequality problem.
To find out the people’s view, the survey covered 10,250 respondents, between the ages of 20 and 30 with a college education and a monthly salary between 1,000 and 3,000 yuan. Surprisingly, most disagreed with the view of experts who claim the urban-rural difference is causing the widening gap. More than 70 percent of the respondents believed that “ the group of special interests” is the prime reason for the polarization, followed by “people in power” 68 percent, and “bosses” 50 percent.
Another unexpected finding is that almost all agreed that a good educational background and knowledge were not the decisive factors in gaining wealth. About 95 percent said rich people are not necessarily those who are able to speak English or have a college education.
Today in China, rich people , accounting for 10 percent of the population, control 45 percent of the total social fortune, and poor people, also 10 percent of the population, only control 1.5 percent, according to an investigation published by the National Bureau of Statistics last June.
1. It can be inferred that the Gini Coefficient ( in paragraph 2) would probably be _____.
A. the unit used in advanced mathematics
B. the degree of a country’s development
C. the level of the citizen’s living standard
D. a measure of income inequality
2. Experts hold the view that the main reason for the polarization is _____.
A. the urban-rural difference B. the group of special interests
C. the people in power D. the bosses
3.Which of the following can show the correct proportion(比例) of the social fortune among population?
4.What’s the best title of the passage?
A. Close the Gap between the Rich and Poor
B. Surveys conducted by China Youth Daily
C. Higher education, Higher pay
D. Rich-Poor Divide Serious, Study Finds
