Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

　　It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随机地) from the population,it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical (完全相同的) twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.

　　Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth playsa part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.

A Battery’s Worst Nightmare(噩梦)

     Portable electronics that can be carried about easily are only as good as their batteries and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life!When the fuel runs out in your laptop or mobile phone, you just fill up and go.

    The engine, about the size of a ten-cent coin, starts with a combustion chamber (燃烧室) that burns hydrogen (氢). Its tiny parts are etched onto silicon wafers (硅片) in the same manner that computer parts are imprinted onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.

     But the devil in all this nice detail is efficiency(效率). Tiny engine parts don’t always behave like their scaled-up parts of the first engine. Something between the parts can slow down the work, according to Columbia University professor Luc Frechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.

    The scientists’ goal is to create an engine that will operate 10 times better than batteries do. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t available until at least the end of the next ten years.

In the summer of 1936, people all over the world heard the name of Jesse Owens. That summer, Jesse joined the best athletes from 50 nations to compete in the Olympic Games. They met in Germany, in the city of Berlin.

There was special interest in the Olympic Games that year.

Adolf Hitler was ruler of Germany. Hitler and his Nazi Party believed that white people—especially German people—were the best race of people on earth. They believed that other races of people—especially those with dark skin—were almost less than human. In the summer of 1936, Hitler wanted to prove his beliefs to the world. He wanted to show that German athletes could win every important competition.

Jesse Owens was black, too. Until 1936, very few black athletes had competed in the Olympic Games for the United States. Jesse was proud to be on the team. He was very sure of his ability.

Jesse spent one week competing in four different Olympic track and field events in Berlin. During that time, he did not think much about the color of his skin, or about Adolf Hitler. At last, Jesse Owens won the highest award—the gold medal—in all four of the Olympic, competitions he entered. In the hundred meter run, he equaled the fastest time ever run in that Olympic event. In the long jump and the 200-meter run, he set new Olympic records. And as part of a four-man team, he helped set a new world record for the 400-meter relay race.
