Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our possibility to give and receive support from one another under stressful conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression(沮丧) to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.

   Social support cushions stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support money aid, material resources, and needed services - that reduces stress by helping us resolve and deal with our problems.

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 endure 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 on 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 box'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 box 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). 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 (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can stand 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.
