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.

    On the basis of cultural relativism, the values of artistic works are simply reflections of local social and economic conditions. Such a view, however, fails to explain the ability of some works of art to excite the human mind across cultures and through centuries.

    History has seen the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries. Unique works of this kind are different from today's popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

    In a 1757 essay, the philosopher David Hume argued that because “the general principles of taste are uniform(不变的) in human nature, “the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

    Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

    Chinese tech giant Tencent Holdings Ltd, the largest global gaming provider and the operator of QQ, an instant messaging software service, has launched a series of scientific exploration events aimed at encouraging young people to explore the outside world, instead of being continuously absorbed online.

    “QQ has been in the market for 18 years, but it is not aging, and its application has become younger and trendier. We hope that more young Chinese can use the app to connect with different people and views worldwide. We never worry about losing game players. Instead, we hope that players can actually go out to learn more,” said Li Dan, general manager of marketing department of the social network group at Tencent.

    China's gaming market netted (净赚) sales revenues of 218.96 billion yuan ( $33.75 billion) in 2017, jumping 23.1 percent year-on-year. Meanwhile, the number of mobile gain players in China reached 462 million, adding 10 percent over the last year. According to Tencent the number of active users of QQ, who are 21 years old or younger, has been increasing, and they tend to use the app for a longer time.

    Starting May 22 of last year, QQ organized free trips for young people to Galapagos, Namibia, Spain and the Antarctic, but it didn't reveal the specific amount it contributed to those trips. During each trip, it selected three to four participants from those who uploaded videos and made specific travel plans online. The finalists stand out with their clear video statements and their enthusiasm about going on adventures.

    “Tencent's approach appears to be contradictory with its own interests. But, in fact, this is consistent with the company's long-term growth strategy and will promote its business by establishing a good social image,” said Neil Wang, president of consulting firm Frost & Sullivan in China.

    With the start of the new term, the students around the country exchange their fun and fashionable clothes for boring school uniforms. But not all schools are fashion deserts. Colorful sports shoes, school bags, T-shirts and even drink containers are breathing life into campuses.

    "The uniform makes us look like a bunch of clones, especially when we are doing morning exercises on the playground," said Qing Pei, a Senior 2 from Shanghai Qibao High School. "But the boys wear different sports shoes and girls have different decorations in their hair. These are the areas where you can express yourself," said Qing.

    Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.

    "Nike and Adidas basketball shoes, although they are still the must-have items for many of my friends, are becoming out-of-date," Qing added. He explained that "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn. "

    "Still in fashion are the various baseball caps and American-style T-shirts with random (随意的) English words printed on them," said Qing. "The accuracy of the written message is not important. Often, the words are not spelt correctly. Sometimes they do not even make sense, "Qing said with a smile.

    Besides sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls.

    Other fashionable items are the colorful drink containers which are now popular among girls this term.

    "Some teachers are surprised to see a teenager sucking a bottle like this at school and criticize it as a childish regression (退化). But some girls just love it," said Yang Rui, a Senior 3. from High School attached to Xi'an Jiaotong University.

    An 114 kilograms mother, Cacia Griggs, was ashamed into losing weight after crushing her daughter, four-year-old Isabelle's bed while reading her a bedtime story.

    Just one year later she has lost 50 kilograms, dropped to a size 10, and even was employed by her dream company.

    One night, having asked her 29-year-old husband to carry Isabelle up to bed because she couldn't fit through the stair gate, Cacia followed them upstairs and lay down on the edge of the bed with her daughter to read her a story.

    “I heard a loud snap(噼啪声),” she said. “I'd broken the entire side beam of her bed because I was overweight. I was upset.”

    On her first family holiday with Chris and Isabelle in Turkey last year, Cacia had a similar moment when she couldn't fit the plane seatbelt around her.

    Cacia began the Cambridge Weight Plan in June 2011, changing her high-calorie diet into soups, shakes and bars. In August this year, Cacia reached her goal weight and dropped from a size 24 to a size 10.

    “My weight began to drop off,” she said. “In no time at all I was wearing smaller clothes and was over the moon the first time I brought a size 16, I couldn't believe it fitted.”

    Cacia says the best thing about losing the weight is being able to lie with her daughter again on her bed instead of sitting on the floor next to her.

    We arrived at the hospital to find Dad was very weak, but his smile was as sure as ever. It was another attack of pneumonia (肺炎). My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from the hospital and look after him. But I longed to be able to let him know that we cared too, even when we weren't with him.

    Then I remembered a family tradition when our children were small. When leaving their grandparents' home after a visit, each child would write a love note to their grandparents. They hid notes in the cereal (麦片) box, under a hairbrush, next to the phone or even in the microwave oven (微波炉). For days, their grandparents would smile as they discovered these signs of our love.

    So as I tidied Dad's kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, “Dad, I put the food in the fridge so it wouldn't spoil.” Some expressed my love, “Dad, I hope you will sleep well in your new bed.” Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, “Dad, if you have found this note, you must be feeling better. We are so glad!”

    Just like his medicines strengthened him physically, these “emotional vitamins” would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, “Pretty good. I just found your note under my pillow upstairs!”
