World Book Day falls on April 23 every year．It was set up by the United Nations Educational,Scientific, and Cultural Organization(UNESCO) in 1995 to encourage people, especially teenagers, to discover the pleasure of reading．It is also the day to honor great writers，for example，William Shakespeare，born or dead on that day．

    Many countries celebrate World Book Day．Take UK as an example．On that day，millions of school children can buy books of special price，a much lower price than usual，in any bookstore．It has been done every year since 1998．World Book Day is also celebrated in China. Our Former Premier Wen Jiabao, a bookworm, who does lots of reading every day, has called on people to do more reading. He suggested that young people should spend more time reading．"Books cannot change the world, but people can change the world by changing themselves through reading,” he said．

    Why do people like reading? One big advantage is that reading helps us become more knowledgeable and more intelligent. Also, reading helps us to follow the latest developments of science and technology. Besides, reading gives us information about other cultures and places of the world. When we read, we may find many things that are unfamiliar to us. We would have to use our brain to think about them or do more reading to find out the answers. The more we read, the more we know. What's more, reading is also one of the most important ways to learn a foreign language like English．

    "Reading makes a full man" (Bacon，1597). Books，magazines，newspapers and other kinds of materials can help us to know more about the outside world and perfect us. So it is necessary for us to spend time on reading every day．

    Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there's no need for a lot of scientific terms or expensive lab equipment. You only have to share your children's curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we're finished with your lists, do you have questions of your own about science?”

    After a long pause, a boy raised his hand, “Have you ever seen a grasshopper （蚱蜢）eat? When I try eating leaves like that, I get a stomachache. Why?”

    This began a set of questions that lasted nearly two hours.

    Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers.

    Thirdly, watch your language. Once you have a child involved in a science discussion, don't jump in with “That's right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That's interesting” or “I'd never thought of it that way before”, or coming up with more questions or ideas.

    Never push a child to “Think”. It doesn't make sense, children are always thinking, without your telling them to. What's more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.

    Lastly, show; don't tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass（放大镜）, and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates（蒸发）, set a pot of water to boil and let them watch the water level drop.

    One night about nine o'clock, Dr. Eyck, a surgeon, had a phone call from Dr. Haydon at the hospital in Clens Falls. The surgeon was asked to go there at once to operate on a very sick boy who shot himself while playing with a gun.

    The doctor was soon on his way to Clens Falls. It was 60 miles away. And it was snowing heavily in the city. The surgeon thought he could get there before 12 o'clock.

    A few minutes later, the doctor was stopped by a man in an old black coat. Gun in hand, the man ordered the doctor to get out. Then the man drove the car down the road, leaving the doctor in the falling snow.

    It was after 2 o'clock in the morning when the doctor arrived at the hospital in Clens Falls. Dr. Haydon told him that the boy had died an hour before.

    The two doctors walked by the door of the hospital waiting room. There sat the man in the old black coat with his head in his hands.

    "Mr. Cuninghan," said Dr. Haydon to the man, "This is Dr. Eyck. He is the surgeon who walked all the way from Albany to save your boy."

    Not all think laughter is the best medicine, but it seems to help. So scientists carried on a new study of diabetes (糖尿病) patients who were given a good dose of humor for a year to prove it.

    Researchers divided 20 high­risk diabetic patients into two groups. Both groups were given standard diabetes medicine. Group L viewed 30 minutes of humor of their choice, while Group C. the control group. did not. This went on for a year of treatments.

    By two months into the study. the patients in the laughter group had lower level of the hormones epinephrine (肾上腺素), considered to cause stress. which is known to be deadly. After the 12 months. HDL cholesterol rises 26 percent in Group L but only 3 percent in Group C. In another measure. C­reactive proteins, a maker of heart disease. drop 66 percent in the laughter group but only 26 percent in the control group.

    “The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter. ”said study leader Lee Berk of Loma Linda University. And other research has found that humor makes us more hopeful. Still, more study is needed, Berk said. The research by Berk found that humor can bring about similar changes in body chemistry. which was proved in the new study. The research result will be presented this month at the meeting in the US. Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand. increasing blood flow in a way thought to be healthy.

    “Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to. rather than prevention and treatment,”Berk said in a statement this week.

    An Israeli law banning too skinny models went into effect with the start of 2013. The law, approved last March in Israel, requires models to prove they have maintained a Body Mass Index (BMI) of at least 18.5 for three months before a fashion show. That means a woman who is 68 inches tall can weigh no less than 119 pounds.

    "This law is another step in the war against eating disorders," said physician Adatto. "Underweight models," he explained, "can no longer serve as role models for innocent young people who copy their false image of being skinny."

    But some critics in this country say it is misguided, focusing on weight instead of health. They also say the Israeli ban is bound to fail because of the strong power of the fashion industry. "I think it's an approach that isn't going to work." said eating disorder expert Susan Ice, who worked with an organization which creates a healthy working environment for models.

    But Adatto told the reporter that he began to concern the issue after meeting an ambitious model who looked like she needed to be hospitalized. He said. "I realized that only legislation(立法) can change the situation. There was no time to waste; so many girls were dieting to death."

    However, the efforts to regulate models' weight in Spain and Italy have not resulted in significant changes in part because of difficulties in determining reliable methods of measuring weight and health.

    Still, folks including Ice say there's no denying that images from Hollywood and the fashion industry can be difficult for young women to deal with. "Certainly I don't believe the modeling industry has caused the rise in eating disorders, but it makes it harder," she says. "It's a difficult recovery environment, worshiping thinness as the beauty ideal."

May 20th has become a popular date for marriage registration among young people in China, as "520" sounds like "I love you" in Chinese, {#blank#}1{#/blank#}has promoted the sales of related products and services such as wedding banquets, roses, {#blank#}2{#/blank#}hotel reservations. According to media reports, many Chinese newlyweds queue up overnight outside the marriage registration office to get married.
