Two students started quarreling at school. One student shouted dirty words at the other, and a fight began. What can be done to stop fights like this at school? In some schools, the disputants sit down with peer mediators(同龄调解者). Peer mediators are students with special training in this kind of problems.

    Peer mediators help the disputants to talk in a friendly way. Here are some of the ways they use:

1) Put what you think clearly but don't say anything to hurt the other. Begin with “I feel…” instead of “You always…”

2) Listen carefully to what the other person is saying. Don't stop the other person's words.

3) Keep looking at the other person's eyes when he or she talks.

4) Try to see the other person's side of the problem.

5) Never put anyone down. Saying things like “You are foolish” makes the talk difficult. 6) Try to find a result that makes both people happy.

    Peer mediators never decide the result or the winner. They don't decide who is right and who is wrong. Instead, they help the two students to find their own “win-win” result.

The healthy adolescent boy or girl likes to do the real things in life,to do the things that matter. He would rather be a plumber's mate and do a real job that requires doing than learn about hydrostatics(流体静力学)sitting at a desk, without understanding what practical use they are going to be. A girl would rather look after the baby than learn about child care. Logically we should learn about things before doing them and that is probably why the experts enforce this in our educational system.But it is not the natural way—nor, in my view, the best way. The adolescent wants to do things first for only then does the appreciate the problems involved and want to learn more about them.

    They do these things better in primitive life,for there at puberty(青春期) the boy joins his father in making canoes,patching huts,going out fishing or hunting.He is serving his apprenticeship in the actual accomplishments of life.It is not surprising that anthropologists(人类学家) find that the adolescents of primitive communities do not suffer from the same neurotic(神经质的) “difficulties” as those of civilized life.This is not,as some assume,because they are permitted more sexual freedom,but because they are given more natural outlets for their native interests and powers and are allowed to grow up freely into a full life of responsibility in the community.

    In the 19th century this was recognized in the apprenticeship system,which allowed the boy to go out with the master carpenter,or ploughman,to engage in the actual work of carpentry or roof-mending,and so to learn his trade.In some agricultural colleges at the present time young men have to do a year's work on a farm before their theoretical training at college.The great advantage of this system is that it lets the apprentice see the practical problems before he sets to work learning how to solve them,and he can therefore take a more intelligent interest in his theoretical work.

    Since more knowledge of more things is now required in order to cope with the adult world, the period of growing-up to independence takes much longer than it did in more primitive community,and the responsibility for such education,which formerly was in the hands of the parents,is now necessarily undertaken by experts at school. But that should not make us lose sight of the basic principle, namely the need and the desire of the adolescent to engage responsibly in the real pursuits of life and then to learn how—to learn through responsibility, not to learn before responsibility.

    You can't see your sleeping pets brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you'll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slow-wave sleep. After about 15 minutes you'll notice a change in her breathing. Her eyes move under her closed lids, her paws twitch (抽动) and she flicks (尤指用手指或手快速地轻抚) an ear. She has entered dreaming. Although she twitches and makes little grunting (嘟嘟) noises, messages from her brain to the large muscles in her legs are blocked, so she can't run about. She is in a state of "sleep paralysis (麻痹)".

    Michel Jouvet, a French scientist, interrupted their sleep paralysis. Even though they were completely asleep, the dreaming cats began to run for balls that Jouvet couldn't see and arched (弓起) their backs at unseen enemies. He figures he was watching them act out their dreams! Obviously, the dreaming cats seemed to be practising important cat skills: following, pouncing (猛扑), and fighting.

    In another study, Matt Wilson recorded rats brain waves while they learned mazes (迷宫). One day, he left the brain-wave-recording machine on while the rats fell asleep. The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!

    Many researchers now think that in both people and animals, one purpose of dreams is to practise important skills and figure out recent caning. This may explain why so many people dream about fighting and escaping, skills that were probably important to our ancestors, and why dreaming affects our ability to learn.

    Do all animals dream? From looking at the brain waves of sleeping animals. How often animals dream seems to be tied to body size. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. And though cows and horses usually sleep standing up, they only dream when lying down.

    America is the world's largest food exporter. But the worst drought in half a century is hitting corn and wheat harvests. The drought across the central United States adds to concerns about world food supplies and prices in the coming years.

    Experts say by 2050, the world will have to produce at least sixty percent more food to feed a population growing bigger and bigger. China, a major food importer, is looking for producers around the world to guarantee future food supplies.

    China has invested in food production in Australia and New Zealand. A new source of supply is Ukraine. Ukraine was known as the breadbasket of Europe because of rich corn and wheat harvests a century ago.

    Galyna Kovtok is chief executive of Ukraine's largest agricultural business, ULF. She predicts that within a few months her company will be approved to export corn to China. That will make Ukraine the first country outside the Americas to do so.

    ULF will soon have almost two million tons of elevator storage capacity as it prepares for the Chinese market. Chinese money is financing the building of six grain elevators. But the company's equipment is largely American, including half-million-dollar John Deere combines to harvest wheat.

    ULF'S grain production per hectare (公顷) is now halfway between Ukrainian averages and the high yields of the American Midwest. But farming depends on the weather. Across the Black Sea region—in Ukraine, Russia and Kazakhstan--drought this year is pushing harvests down by fifteen to twenty percent.

    Traditionally, the Black Sea region is the main source of wheat for North Africa and the Middle East. But this year, on the supply side, Russia may have to stop exports. And, on the demand side, Africa and the Middle East are now competing with China.

    At the same time, a new report says large parts of Asia may face long periods of severe drought within ten years. It says northern China, India, Afghanistan, Mongolia and Pakistan will be especially hard hit. It says other parts of Asia are likely to face longer and wetter monsoon seasons (雨季) because of climate change.
