As people continue to grow and age, our body systems continue to change. At a certain point in your life your body systems will begin to weaken. Your joints may become stiff. It may become more difficult for you to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer, we have always tried to slow or stop this process that leads us toward the end of our lives. Many factors contribute to your health. A well-balanced diet plays an important role. The amount and type of exercise you get is another factor. Your living environment and the amount of stress you are under is yet another. But scientists studying senescence(衰老) want to know: Why do people grow old? They hope that by examining the aging process on a cellular level medical science may be able to extend the length of life.

Stranger: Excuse me, do you have small change for a dollar? Passer-by: ______

In the same way that a child must be able to move his arms and legs before he can learn to walk, the child must physiologically be capable of producing and experiencing particular emotions before these emotions can be modified through learning. Psychologists have found that there are two basic processes by which learning takes place. One kind of learning is called "classical conditioning". This occurs when one event or stimulus is continuously followed by a reward or punishment. It is through classical conditioning that a child learns to associate his mother"s face and voice with happiness and love, for he learns that this person provides food and comfort. Negative emotions are learned in a similar fashion. The second kind of learning is called "operant"(动作的) conditioning. This occurs when an individual learns to do things that produce rewards in his environment and learns not to do things that produce punishments. For example, if a mother always attends to her baby when he cries and cuddles him until he is quiet, she may teach him that if he cries he will get attention from mother. Thus, the baby will learn to increase his crying in order to have his mother more.

Some psychologists maintain that mental acts such as thinking are not performed in the brain alone, but that one"s muscles also participate. It may be said that we think with our muscles in somewhat the same way that we listen to music with our bodies. You surely are not surprised to be told that you usually listen to music not only with your ears but with your whole body. Few people can listen to music that is more or less familiar without moving their body or mom specifically, some part of their body. Often when one listens to a symphonic concert on the radio, he is tempted to direct the orchestra even though he knows there is a competent conductor on the job. Strange as this behavior may be, there is a very good reason for it. One cannot derive all possible enjoyment from music unless he participates, so to speak, in its performance. The listener "feels" himself into the music with more or less noticeable motions of his body. The muscles of the body actually participate in the mental process of thinking in the same way, but this participation is less obvious because it is less noticeable.

The economy in the United States is heavily dependent on aluminum, a material widely used in the construction of buildings and in making such diverse things as cars, airplanes, and food containers. In 1979 Americans used over five million tons of new aluminum, and one and a half million tons of recycled aluminum. Some ninety percent of the bauxite (矾土) ore from which new aluminum is normally derived had to be imported to meet the demand. Poorer ores are abundant in the United States, however, researchers at Purdue University may recently have found a way to obtain aluminum magnetically from these. Although aluminum is not attracted by ordinary magnets, under special conditions it becomes temporarily "paramagnetic", or very weakly responsive to a magnetic field. This is achieved by immersing ore particles in water to which certain salts have been added and then filtering the ore through steel wool in the presence of a strong magnetic field. It is hoped that this technique will reduce the amount of high-grade aluminum the United States must import.

Jessica Bucknam shouts "tiao!" (tee-ow) and her fourth-grade students jump. "Dun!" (doo-wen) she commands, and they crouch(蹲). They giggle(吃吃地笑) as the commands keep coming in Mandarin Chinese. Half of the 340 students at the K-5 school are enrolled in the program. They can continue studying Chinese in middle and high schools. The goal: to speak like natives. About 24,000 American students are currently learning Chinese. Most are in high schools. But the number of younger students is growing in response to China"s emergence as a global superpower. "China has become a strong partner of the United States", says Mary Patterson, Woodstock"s principal. "Children who learn Chinese at a young age will have more opportunities for jobs in the future". Isabel Weiss, 9, isn"t thinking about the future. She thinks learning Chinese is fun. "When you hear people speaking in Chinese, you know what they"re saying", she says. "And they don"t know that you know".

Watch out! Here comes London Mayor Boris Johnson riding a bicycle from his new bike hire plan. "What we"ve put in is a new form of public transport. These bikes are going to belong to everybody. " More than 12, 000 people have signed up for the plan. They each receive a key at a cost of three pounds, with cost at one pound for a 24-hour membership, five pounds for seven days, and 45 pounds for an annual membership. John Payne, a London teacher who cycles a lot, is among the first to use the system. "It"s very comfortable. For people who don"t cycle much I think it"ll be very useful. But for people who cycle regularly, they are possibly a bit slow. But they"re perfect for London streets, very strong. I think they"ll be very widely used. " And Johnson says it"s of good value. "I think it"s of extremely good value. The first half hour is free. If you cycle smart and you cycle around London—most journeys in London take less than half an hour, you can cycle the whole day free. " Some 5, 000 bikes are currently available at over 300 docking stations(租车点)in central London. Johnson says the city will gradually expand the system. "Clearly one of our ambitions is to make sure that in 2012 when the world comes to London, they will be able to use London hire bikes to go to the Olympic stadiums. "
