Is there anything more important than health？I don't think so. You can't be good at your studies or work when you are ill. If you have a headache，or a bad cough，if you run a high temperature and have a bad cold，I think you should go to the doctor. The doctor will examine your throat，feel your pulse，take your temperature，sound your heart and lungs. After that he will advise some treatment，or some medicine. The only thing you have to do is to follow his advice.

    Speaking of doctor's advice, I can't help telling you a funny story. An old man 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 at pleasure，drink with measure 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.”

    Every day, a homeowner in Pennsylvania is reminded of a mistake he made 13 years ago. At around 8 in the evening, his peaceful house comes alive with the noise of an alarm clock he dropped into the wall over ten years ago. It's been stuck in the wall ever since.

    13 years ago, Jerry Lynn wanted to make a hole through his living room wall, so he could pass the television cable (电缆)through it. He didn't want to destroy any pipes in the wall, so he came up with a good idea to make sure that he was drilling(钻孔) in an empty place. He took his alarm clock, tied it to a string(线) and set it to go off in 10 minutes. Then he lowered it into the wall, and waited for it to ring. His goal was to drill a hole in a safe place near the place where the ringing was coming from, making sure that there was nothing to pass through there. It all went smoothly until the alarm clock fell into the wall.

The man didn't get back the alarm clock, but thought it would probably run out of battery(电池)in several months, so he wasn't too worried about it. But 13 years later, the alarm clock still rings every day.

    As you can imagine, Jerry and his wife have gotten used to the ringing living room wall, but it can still surprise  guests. So Jerry decides to pull down that wall, just to stop that boring thing, though after putting up with it for 13 years, he think it will be a pity. He says, “I've never herd of a clock battery lasting that long and my friends think it may be interesting to see how long it will keep ringing for.”

    A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

    Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

    In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

    The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo's Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

    One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

    Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

    The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

    The New Caledonia Barrier Reef (新喀里多尼亚堡礁)is located in New Caledonia in the South Pacific, and is the second-longest coral reef in the world, after Australia's Great Barrier Reef. The New Caledonia Barrier reef surrounds Grand Terre, New Caledonia's largest island, as well as the Ile des Pins and several smaller islands, reaching a length of 1, 500 km. The reef encloses(围住) in a lake of 24, 000 square kilometers, which has an average depth of 25 meters. The reefs lie up to 30 kilometers from the shore, but extend almost 200 km to the Entrecasteaux reefs in the northwest. This northwestern extension encloses the Belep Islands. Several natural passages open out to the ocean. The Boulari passage(通道), which leads to Noumea, the capital and chief port of New Caledonia, is noted for the Amedee lighthouse.

    The reef has great species diversity with a high level of endemism(动植物的特有分布), and is home to endangered dugongs, a kind of sea animal, and is an important nesting site for Green Sea Turtle.

    Most of the reefs are generally thought to be in good health. Some of the eastern reefs have been damaged by wastewater from nickel mining(镍开采)on Grand Terre. The waste from mining, agriculture, and grazing(放牧) has affected reefs near river mouths, which has been worsened by the destruction of mangrove forests, which help to keep wastes. Some reefs have been buried under several meters of wastes.

    In January 2002, the French government proposed(提议) listing New Caledonia's reefs as a UNESCO World Heritage Site. UNESCO listed New Caledonia Barrier Reef on the World Heritage List on 7 July 2008.

    Teens may become more private during adolescence (青春期) because they are learning how to be more independent, says Carl Pickhardt, a Texas­based scientist who studies parenting adolescents. "As they enter adolescence, parents have less control," he says. "You're going to have less communication with the kid who is now entering a larger and more risky world."

    However, Pickhardt says, this does not mean that parents should just sit back and do without any information. He says that parents should tell their kids that there are still things they need to know about, such as why their teen was late getting home from school one day.

    Iowa's mom Patty Link knows this fight well. The mom of three is raising two teenage boys: Graham, a 14-year-old eighth grader, and Carter, a 16-year-old high school student. She says that becoming friends with the parents of her children's friends has helped.

    "A lot of times if I want to get any information out of them, I'll say, 'Oh, I can talk to Adam's mom and she will tell me what was going on Friday night', and it will lead to some other discussion, "she says.

    Parents should watch their use of questions, Pickhardt says, because they can stand for authority (权威), and that is likely to not go over well with teens. "They want their independence to be respected, "he says. Pickhardt suggests using requests such as, "It could really help me if you could tell me," "I would really appreciate it if you let me know, "or "Could you help me better understand." But sometimes teens make mistakes and parents have to correct them. Parents should plainly (直率地) state the problem, Pickhardt says, and avoid judgments of character.

    Parents can also use technology to feel connected. One recent study showed that many teens are friends with their parents on Facebook—and only 5 percent limit what their parents can see.
