Children have their own rules in playing games. They seldom need a referee(裁判) and rarely trouble to keep scores. They don't care much about who wins or loses, and it doesn't seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be directly compared. They also enjoy games that move in stages, in which each stage, the choosing of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in itself.

    Grown-ups can hardly find children's games exciting, and they often feel puzzled（迷惑的）at why their kids play such simple games again and again. However, it is found that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he has caught.

    It appears to us that when children play a game they imagine a situation under their control. Everyone knows the rules, and more importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.

    Dazha Crabs from Yangcheng Lake

    With the Mid-Autumn Festival coming, the time for crabs is around the corner! Dazha Crabs from Yangcheng Lake in China are believed to be the best freshwater crabs.

    “They are delicious, because the bottom of Yangcheng Lake is hard and the crabs grow strong by walking on such a hard surface,” said one sales manager in Suzhou.

    Li Lei, a crab lover from Beijing, said “It's very delicious! But there are too many fake Yangcheng Lake Dazha Crabs”.

    “Maybe the crabs from other regions can appear to be glistening green back, white belly after people wash them, but the golden fine hair on crab claws is still a point of pride and is exclusive to Dazha Crabs from Yangcheng Lake,” said the manager.

    The best time for enjoying them is during September and October of Chinese lunar calendar. “When the season for crabs arrives, the Dazha Crabs from Yangcheng Lake are flown to various cities so that people's appetites can be satisfied,” said the sales manager. “They are really expensive here, sometimes more than 320RMB/500g, 10% of my salary!” said Li Lei.

    Dazha Crabs are usually steamed or boiled for within 20 minutes before they come on the dinner table. They are often enjoyed with vinegar mixed with minced ginger to add flavor and get rid of the cold. People who are particular about how they eat crabs also need to have high-grade Shaoxing rice wine to warm their stomachs.

    There is much work required to eat crabs. So much shell!Most people use both hands and teeth while eating Dazha Crabs. “The eating way is not graceful or elegant,” said Huck. “However, some professionals of eating crabs can use tools to take all the meat out of the crab without damaging a single bite and the crab can be restored to its original shape if the empty shells are pieced together!” said Han Mei, another Dazha crab lover.

    At no time in history has there been such a mass movement of people from the countryside to the city as is happening now. By the year 2030, it's estimated that more than two thirds of the world's population will be living in cities, twice as many as today. This means that the problems faced by cities today-overcrowding, poor housing, unemployment, poverty and lack of food and water—will be twice as bad, unless we find solutions soon.

    Another serious issue is how to provide good transportation for their citizens. Many of the world's major cities are already struggling with out-of-date transport infrastructures (基本设施). How can they deal with the additional demands?

    London is a good example. Its enlargement was made possible by the invention of the steam engine, which powered the world's first underground railway. But its transport system are now hopelessly out-of-date and need urgent modernization. London's future success depends very much on developing better public transport

    Over a million people travel into central London every day from outside the city. They, together with the people who live in London, want a public transport system that is efficient, safe and environmentally friendly. What they often get, however, falls far short of that ideal. Passengers complain about cost and pollution, while businesses worry about the problems their staff have in getting to work on time. Yes, the proportion of London households that own a car grew from just over ten percent in the early 1950s to over sixty percent today.

    As the city has become increasingly crowded and polluted, there has been a growing realization that action must be taken soon.

    English teenagers will receive cooking lessons in schools. The idea is to encourage healthy eating to solve the problem that many people are overweight. Also, it worries people that basic cooking and food preparation skills are being lost because parents use too much pre-prepared fast food.

Cooking was once regarded as an important part of education in England—even if it was mainly for girls. In recent years cooking has become less important in schools. But the rising level of obesity has led to rethink about the food that children are given and the skills they should be taught.

    “What we want is to teach young people how to do basic, simple meals, which they can use now at home and then in their life,” said Ed Balls, an education expert.

    The new lessons will start in September, but some schools without kitchens will be given a longer time to prepare. Also, there may be a shortage of teachers with the right skills, since schools have been teaching food technology rather than practical cooking. Besides, the lessons for hand-on cooking will only be one hour a week for one term. But the well-known cookery writer, Pru Leith, believe it will be worth it.

    “If we'd done this thirty years ago we might not have to face the problem about obesity and lack of knowledge about food and so on. Every child should know how to cook, not just so that they'll be healthy, but because it's a life skill which is a real pleasure.”

    The renewed interest in cooking is an effort to reduce the obesity rate, which is almost the highest in Europe, and according to the government, half of all British people will be obese in 25 years if present trends are not halted.

New discoveries and technological breakthroughs are made every year. Yet, as the information industry moves forward, many people in society are looking back to their roots in terms of the way they eat. A "locavore" movement has emerged in the United States. The movement supports eating foods grown locally and sustainably, rather than prepackaged foods shipped from other parts of the world.

Experts hold that eating local has many merits, and is expected to become a trend featuring sustainability. Erin Barnett is the director of Local Harvest, a company that aims to help connect people to farms in their area. By eating local, she argues, people have a better and more personal understanding of the impact their food consumption has on the rest of the world. "There is a way of connecting the point, where eating locally is an act that raises our awareness of sustainable living," Barnett says.

The United States' agricultural output is one of the highest in the world, says Timothy Beach, a professor of geography and geoscience at the University of Texas in Austin, Texas. "There's just no other place on Earth where the amount of input is so productive," Beach says of American agriculture. "Nobody can cut off the food we need."

However, the US food system is not sustainable because of its dependency on fossil (化石) fuels, says Beach. Equipment used on "extremely productive" farms is quickly consuming Earth's natural resources, particularly oil. Additionally, the production of agricultural supplements (补充剂)，such as fertilizer, uses large amounts of energy.

The world has used close to half of the global oil supply, Beach says, and the second half will be consumed at an even faster rate because of the growing population and economic development. Although many businesses are experimenting with wind, solar, and biofuel, Beach says there's nothing that we see on the horizon that can replace it. "There is no way on Earth we are using fossil fuels sustainably. Then we have to reconsider the impact of eating local," he says.
