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.

    Gaudi's otherworldly imagination

    Designed by one of Spain's most famous architects, Antoni Gauldi, the Roman Catholic church Sagrada Familia is a legend in itself Construction began in 1882, but less than a quarter of the project was complete when Gaudi died in 1926. Since then, work has progressed slowly. How about the ending? Architects plan to complete the project in 2026, the centenary of Gaudi's death.

    As Barcelona's most popular tourist site, Sagrada Familia attracts three million visitors every year for one good reason: It's a masterpiece unlike anything else in the world which is largely responsible for the city's lively personality.

    A setting that could steal the spotlight from any storybook hero

    With its valleys surrounded by lakes, rivers, hills and peaks, the Lake District in England's northwest is quite literally taken out of fairy tales. This place was Beatrix Potter's inspiration for Peter Rabbit and the residence（居所）of the Lake Poets, including William Wordsworth, Samuel Taylor Coleridge and Robert Southey.

    One of nature's most magical illusions

    Once upon a time in the faraway land of the Faroe Islands, Lake Leitisvatn became known as the most striking of all the islands' lakes. At more than 6km long, it is the biggest in the Faroe Islands. In reality, Lake Leitisvatn is actually no more than about 30m above sea level. A steep cliff in front of the lake and a clever camera angle make the lake appear to be much higher than it really is.

    Vinegar is great. It makes salad, fries and dumplings taste better, and you can even clean your windows with it. And now, according to scientists, it may even help the planet's population survive climate change.

    Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have found that growing plants in vinegar makes them more resistant to droughts. This could mean that in the future, worries about climate change affecting the world's supply of food will be much lower.

    The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought-like conditions, it produced a chemical called acetate(醋酸盐)—the main component of vinegar.

    After discovering this, the scientists experimented further by adding acetate to the soil of other plants, and they stopped giving them water completely. After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died. It's hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive.

    Jong Myong Kim, co-author of the study, tells Popular Science magazine that he's already been in touch with people all over the world who are interested in trying this simple and cost-effective method out for themselves from flower growing companies to amateur gardeners. Although at this point keeping thirsty plants alive isn't as easy as just pouring vinegar over them, Kim says he and his team are working on making the process as simple as possible. "Now we are trying to cooperate with some farmers, and also some companies, to make a method to apply this system," he says.

    And for those of us who always forget to ask our neighbors to water our plants when we go away, hopefully this means the end of returning home from a trip to find our favorite flowers have died.
