Animals Can Sense Natural Disasters
Among the dead in South Asia’ s tsunami（海啸）were many tourists at Sri Lanka’ s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and run away to safety.
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound（次声）. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration（震动）. The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints（关节）, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears.
【小题1】Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

In the course of working my way through school, I took many jobs I would rather forget. But none of these jobs was as dreadful as my job in an apple plant. The work was hard, the pay was poor; What’s more, the working conditions were terrible.
First of all, the job made huge demands on my strength. For ten hours a night, I took boxes that rolled down a metal track and piled them onto a truck. Each box contained twelve heavy bottles of apple juice. I once figured out that I was lifting an average of twelve tons of apple juice every night.
I would not have minded the difficulty of the work so much if the pay had not been so poor. I was paid the lowest wage of that time—two dollars an hour. Because of the low pay, I felt eager to get as much as possible. I usually worked twelve hours a night but did receive a low pay.
But even more than the low pay, what made me unhappy was the working conditions. During work I was limited to two ten-minute breaks and an unpaid half hour for lunch. Most of my time was spent outside loading trucks with those heavy boxes in near-zero-degree temperatures. The steel floors of the trucks were like ice, which made my feet feel like stone. And after the production line shut down at night and most people left, I had to spend two hours alone cleaning the floor.
I stayed on the job for five months, all the while hating the difficulty of the work, the poor money, and the conditions under which I worked. By the time I left, I was determined never to go back there again.

Young people and older people do not always agree with each other. They sometimes have different ideas about living, working and playing. But in one special program in New York State, adults and teenagers live together in a friendly way.
Each summer 200 teenagers and 50 adults live together for eight weeks as members of a special work group. Everyone works several hours each day. They do so not just to keep busy but to find meaning and enjoyment in work. Some teenagers work in the woods or on the farms near the village. Some learn to make things like tables and chairs and to build houses. The adults teach them these skills.
There are several free ho urs each day. Weekends are free, too. During the free hours some of the teenagers learn photo-taking or painting. Others sit around and talk or sing. Each teenager chooses his own way to spend his free time.
When people live together, rules are necessary. In this program, the teenagers and the adults make the rules together. If someone breaks a rule, the problem goes before the whole group. They talk about it and ask, “Why did it happen? What should we do about it?”
One of the teenagers has this to say about the experience, “You stop thinking only about yourself. You learn how to think about the group.”
【小题1】In one special program in New York, young and older people              .

You never see them, 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 (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 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 rear of the plane – the area least subject to（易遭受）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 withstand 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.
【小题1】What information could be found from the black box on the Yemeni airliner?

As we all know, nature has supplied every animal except man with some covering for his body such as fur, feathers, hair, and shells as a thick hide. But man has nothing but a thin skin.
If someone were to ask you, "Why did human beings start to cover their bodies with clothes?" most would answer, "To keep themselves warm, of course."
It is only when we begin to think about it a little that we realize that clothes are worn for a great many reasons that have nothing to do with our need for warmth at all.
For example, we wear clothes to some degree in order to decorate ourselves－to make ourselves, if possible, look more dignified (尊严) or nicer.
Clothes of a special kind are often worn to show that the wearer has authority or power. The individual wearing them is treated with respect because he occupies a certain office. The judge on the Bench, for example, might look a very ordinary and unimpressive figure without his wig and gown. Clothes are an important part of ceremony, whether it is connected with belief, the law, parliament, and royalty, the fighting forces or the state. How very different the Queen's Coronation ceremony (加冕仪式) would have looked without the robes, coronets and the cloth of gold.
Sometimes, even in some modern countries people wear some article of clothing, or some jewel, because they believe that it will bring them luck or protect them from evil or illness, or because it is connected with their beliefs.
None of these reasons for wearing clothes－to decorate ourselves, to show our position in the world, for ceremonial purposes, for "luck", to give ourselves dignity and authority－have anything to do with our need for warmth.
