| Beijing had its biggest snowfall since 1951. Britain is suffering through its longest cold snap (寒潮) since 1981. And freezing weather is hitting the Deep South, including Florida"s orange groves and beaches. Whatever happened to global warming? Such weather doesn"t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn"t contradict global warming at all - it"s just a temporary phenomenon in the long-term heating trend. "It"s part of natural variability," said Gerald Meehl, a senior scientist. With global warming, he said, "we"ll still have record and cold temperatures. We"ll just have fewer of them." Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes. But experts did not connect the current cold snap to climate change. So what is going on? "We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere", Arndt said. In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently, this air flow has become bent into a zigzag (之字形) pattern, wandering north and south. If you live in a place where it brings air up from the south, you get warm weather. In fact, record highs were reported this week in Washington state and Alaska. But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from the north. And that"s how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time to time, but it is not clear why it"s so strong right now. | |||||||||||||||

| Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer. __1 _ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They cannot or will not express it. This is called repressing anger. For years many doctors thought that repressing anger was more dangerous to a person"s health than expressing it. They said that when a person is angry, the brain release the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. __2__ Some doctors say that both repressing and expressing anger can be dangerous. They believed that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood of pressure. __3__ They say the first step is to admit that you are angry and recognize the real cause of the anger, then decide if the cause is serious enough and get angry about. If it is, they say, " 4 . Wait until your anger has cooled down and you are able to express yourself calmly and reasonably." Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. __5__ | |||||||||||||||
