Many blind people use guide dogs to help them get safely from place to place and to warn them of danger. But what can blind people do if they are allergic(过敏的) to dogs or just don't like them? For these people, they can turn to the Guide Horse Foundation.

    Janet and Don Burleson founded(成立) the organization in 1999. They began training miniature horses to help guide blind people. Miniature horses look just like common horses, only much smaller. They are generally less than 34 inches tall.

    Cuddles was the foundation's first guide horse in full service. She became 45-year-old Dan Shaw's helper. Shaw has an eye disease and his sight is very poor. One night, while filling out a form to get a guide dog, Shaw heard a news story on TV about people training horses to guide the blind. Shaw loves horses and wanted a guide animal that would live a long time. So he applied(申请)，and a year later, Cuddles and Shaw began training as a team.

    On a trip to New York, Cuddles helped Shaw safely visit many places of interest .They even traveled on a boat and on the subway system.

    Shaw says that he is very lucky to have Cuddles. He believes that Cuddles has changed his life for the better by giving him the chance to do things himself and making him feel much more confident about himself.

    If it really is what's on the inside that counts, then a lot of thin people might be in trouble.

    Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.

    “Being thin doesn't surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.

    According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.

    Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes(糖尿病). They want to prove that internal fat damages the body's communication systems.

    The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no shortcut. Exercise has to be an important part of your lifestyle.” Bell said.

    I don't think there is anything more important than health. “Health is the greatest wealth，” wise people say. You can't be good at your studies or work well when you are ill.

    If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.

    Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: "Eat with pleasure, drink with pleasure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man." But you know, doctor," he said, “it's not easy to begin smoking at my age.”

    For Suilasaikhan, a man living in the Inner Mongolia Autonomous Region(IMAR)(内蒙古自治区), life was hard years ago. When the wind blew, the sand made it almost impossible for him to see anything. He had to find his way back home by following the barking of dogs.

    Thankfully, things are much better today. About one third of the desert is now covered with trees, and sandstorms are less common. Ian Teh, who comes from Malaysia, came to China last year and was amazed to see people planting trees in the several deserts in northern China. "To be honest, it was hard to imagine it was ever a desert at all," he said.

    These are the results of Chinas years-long efforts to deal with desertification (沙漠化). In the 1950s, this widespread problem affected the life of about 400 million people in 18 provinces and autonomous regions in China. So China started several programs to deal with it. For example, the Three-North Shelter Forest Program, saw thousands of trees planted in northern China.

    In 1994, China joined the United Nations' convention (公约) against desertification and created the world's first law on sand prevention in 2001. With these efforts, the past five years have seen the area of desert in China decrease by 242,400 hectares.

    Desertification isn't the problem only in China. With china's success in dealing with desertification, the United Nations Environment Program (UNEP) believes the country is a good example for other countries to follow. "China is one of the most successful countries in greening the desert and has lessons to share with the world." UNEP Executive Director Erik Solheim told Xinhua.

    The islands of Malta and Gozo are brilliant for a family holiday, packed with fun places to visit whatever your children's ages. The islands' small size means everywhere is within easy reach.

    Sandy beaches and swimming spots

    One of Malta's best beaches for families is soft-sanded, sheltered Golden Bay. Older children can try activities such as stand-up paddle boarding, sailing or windsurfing, while the gentle slope of the beach makes it easy for younger kids to safely paddle in the sea.

    Eating out

    Children are welcome at most restaurants, though more upmarket places often only accept older kids. There are often kids' menus that tend to offer pizza, but you can always ask for a half portion of a starter dish (portions are huge in Maltese restaurants). With a wide range of cuisines on offer, children are bound to find something they'll like, Maltese food is strongly influenced by Italian cuisine, so there's pizza and pasta galore, and some kids will love the national dish-fried rabbit

    Accommodation

    Try to schedule at least a few days on Gozo as there are lots of self-catering farmhouses with pools to rent and it's even easier to get around than Malta. Smaller hotels in Valletta usually only accept older children.

    Transport and other tips

    The easiest way to get around Malta and Gozo is to drive, but the local bus service is reliable, easy to use, and fairly inexpensive. Buses are frequent between major towns, but only roughly hourly to and from smaller places. Ferries run between Malta and Gozo, and you can take tourist boats over to Comino.

    Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The “eco-guilt” brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.

    Perhaps that explains why a new book by Bjorn Lomborg received so much popularity. That book, The Skeptic Environmentalist, declares that it measures the “real state of the world” as fine. Of course, another explanation is the deep pockets of some big businesses with special interests. Indeed, Mr. Lomborg's views are similar to those of some Industry-funded organizations, which start huge activities through the media to confuse the public about issues like global warming.

    So it was strange to see Mr. Lomborg's book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that “After Lomborg, the environmental movement will begin to die down.”

    Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg's “preference for unexamined materials is incredible(不可信的)”.

    A critical (批判的)eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blinded before a world partially exhibited by the media. That's a shame, because matters concerning the health of the planet are far too important to be treated lightly.
