Feifei, an 11-year-old boy from Xuzhou, Jiangsu Province, suffered from a sudden acute eye disease which has almost led to blindness. The disease was caused when he overused his eyes during the winter vacation, during which he played computer games for continuous 10 days and nights.

    Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products. This is followed by a series of health problems, with the most typical case being myopia, or nearsightedness.

    According to the latest research report released by the World Health Organization (WHO),the myopia rate among Chinese teenagers ranks first in the world—70 percent of high school and college students. The rate is nearly 40 percent in primary school students, while it is only 10 percent for their peers in the United States.

    There are at least 10 million people in China with severe myopia, and they are likely to get pathological myopia（病理性的近视） in middle age. Pathological myopia can't be treated with glasses or surgery, and it is one of the biggest factors that lead to blindness, Xu Xun, an expert at Shanghai General Hospital, pointed out.

    Experts explain that two major factors lead to the high rate of myopia among Chinese people. One is high academic pressure, and the other one is excessive use of electronic devices over a long period of time. Genetics, on the other hand, are not the main reason, as only 20 percent of Chinese people had myopia in the 1960s.

    "Teenagers are now faced with severe academic pressure, which means they often study without natural light. This increases their risk of becoming nearsighted," Xu said. Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process.

    Memory, they say, is a matter of practice and exercise. If you have the wish and really make a conscious(自觉的) effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory “tricks” work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber(理发师) shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never get tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when “tricks” of our memory can cause us great trouble.

    There are several ways from which to choose for you to keep your kids safe in your neighborhood. But the first step to keep your child safe in your neighborhood is to know your neighbors.

    Knowing your neighbors can save you a lot of worry. It lets you know that the car that has just driven down the street belongs to “the yellow house on the corner”, or the truck that has just driven by the playground looks unfamiliar, but the guy in the passenger seat resides two doors down. It's these simple things that keep you from going out of your mind whenever you see someone driving by where children are playing.

    But you shouldn't just know what they look like. The next step is to know them well. What do they do? How do they act? You might be OK with them driving by the playground since they live in the neighborhood, but are you OK with them being on the playground? Knowing your neighbors solves several things. First you find out what kind of people they are. This helps you know if you should let your child go out in an area where they gather. Let us face it: you do not want your child to play around people or people's children that curse (咒骂) or hit each other. Sometimes you have to protect your child against your own neighbors.

    Knowing them also makes them know you. Being neighbors is an interesting thing. You might not like them or have the same views as them, but we all usually protect those that we consider our own. If you know your neighbors, they know you. They are more likely to look after the child of the nice lady down the street in the brick (砖) house, than the people, in the house on the corner, who no one ever sees.

    The key to effective cross-cultural communication is knowledge. First, it is essential that people understand the potential problems of cross-cultural communication, and make a conscious effort to overcome these problems. Second, it is important to assume（假定）that one's efforts will not always be successful, and adjust one's behavior appropriately.

    For example, one should always assume that there is a great possibility that cultural differences are causing communication problems. One should respond slowly and carefully in cross-cultural exchanges, not jumping to the conclusion that you know what is being thought and said.

    William Ury's suggestion for heated conflicts is to stop, listen, and think, or as he puts it "go to the balcony" when the situation gets tense（紧张的）. This helps in cross-cultural communication as well. When things seem to be going badly, stop or slow down and think. What could be going on here? Is it possible that I misinterpreted what they said?

    Active listening can sometimes be used to check this out—by repeating what one thinks he/she heard, one can confirm that he/she understands the communication accurately.

    Often intermediaries（调解人）can be helpful in cross-cultural communication situations. They can translate both the essential meaning and the manner of what is said. For example, they can tone down strong statements that would be considered appropriate in one culture but not in another, before they are given to people from a culture that does not talk together in such a strong way. They can also adjust the timing of what is said and done. Some cultures move quickly to the point; others talk about other things long enough to establish a relationship with the other person. If discussion on the primary topic begins too soon, the group that needs a "warm up" first will feel uncomfortable. An intermediary who understands this can explain the problem, and make appropriate adjustments.

    A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.

    A private American organization called Population Action International did the new study. It says more than 335 million people lack enough water now. The people live in 28 countries. Most of the countries are in Africa or the Middle East.

    P-A-I researcher Robert Engelman says by the year 2025, about 3,000 million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on the earth stays the same.

    Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

    The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

    The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

    The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

    The traditional British pub is part of the scenery of British life. At the last count, there are around 50,000 of them in the UK. The oldest – Ye Olde Fighting Cocks in St. Albans – was set up in about 793.

    Because of their abundance, the names pubs take are designed to be memorable, but more than that, they are designed to be visual. Outside any traditional pub worthy of its title, you'll find a hanging signboard with an unusual and uncommon illustration(插图) that represents the name of the business. The practice is so well established that even new pubs copy it. But why do they exist at all?

    The first British pub signs were created in the 12^th century and were simple representations of beer containers and other brewing-related equipment used to tell passersby that establishments sold beer. This was Britain in the dark ages, when education was in short supply. Since most of the population was unable to read, pub signs were used to inform would-be customers that they could find a drink inside.

    The earliest uses of pub names would reference the sign directly. People would appoint to meet at "the sign of the Eagle and Child" rather than at "the Eagle and Child".

    Today the tradition remains unchanged largely out of respect for the past, but many pub signs do have some functionality. Remote country pubs often use signboards to point the way to their doors. It's a part of British culture that's rapidly disappearing – more than 20,000 pubs have closed since 1980 – but for now there are still more than enough. You can take a moment to appreciate the history and symbolism behind a pub's sign the next time you see one.
