A majority of Chinese youth are keen on having a car of their own which they think is a reflection of their social status.A nation-wide survey conducted by China Youth Daily found more than a half of the respondents are planning to buy cars very soon.大部分中国年轻人都热衷于给自己买辆车,因为他们认为这是拥有一定社会地位的体现。日前由《中国青年报》发起的一项全国性调查显示,超过一半的被调查者计划在不久的将来买车。The survey polled 1,541 respondents, 40 percent of whom were from small and medium-sized cities, and 43 percent were from provincial capitals. Of the respondents, 60 percent said they were planning to buy a car during the next five years, while 16 percent aly had one. Only 21 percent ruled out buying a car.该项调查对象有1541人,40%来自中小城市,43%来自省会城市。其中60%的人称将会在未来五年内买部车,而16%的人已经拥有了一部。只有21%的人表示不考虑买车。 /201009/113487

Beijing had its coldest morning in almost 40 years and its biggest snowfall since 1951. Britain is suffering through its longest cold snap since 1981. And freezing weather is gripping the Deep South, including Florida#39;s orange groves and beaches.北京遭遇了近40年来最寒冷的清晨和1951年以来最大的降雪;英国正遭遇自1981年来持续时间最长的寒潮;美国包括佛罗里达的橘园和海滩在内的南部地区也未逃过严寒袭击。Whatever happened to global warming?那么全球变暖又是怎么一回事?Such weather doesn#39;t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn#39;t disprove global warming at all - it#39;s just a blip in the long-term heating trend.科学家一直警告说温室气体排放正导致全球变暖,但这样的天气与这种说法似乎并不相符。但专家们称,寒潮和全球变暖并不矛盾——这只是变暖过程中的一个暂时现象而已。;It#39;s part of natural variability,; said Gerald Meehl, a senior scientist at the National Center for Atmospheric Research in Boulder, Colo. With global warming, he said, ;we#39;ll still have record cold temperatures. We#39;ll just have fewer of them.;位于美国科罗拉多州尔德的国家大气研究中心的资深科学家杰拉尔德#8226;弥尔说:“这是大自然易变性的一个表现。”他说,在全球变暖的同时,“我们仍然会遭遇创纪录的低温天气,只是这样的天气会减少。”Deke Arndt of the National Climatic Data Center in Asheville, N.C., noted that 2009 will rank among the 10 warmest years for Earth since 1880.位于北卡罗来纳州艾西维尔市的国家气象数据中心的德科#8226;阿恩特指出,2009年将是自1880年以来气温最高的十年之一。Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes, such as heat waves, storms, floods, droughts and even cold spells. But experts did not connect the current frigid blast to climate change.科学家说,人为的气候变化的确会带来更为频繁和更严重的极端天气,如热浪、暴风雨、洪水、干旱甚至持续的寒冷天气。但科学家没有把目前的严寒天气和气候变化联系在一起。So what is going on?那么这究竟是什么原因呢?;We basically have seen just a big outbreak of Arctic air; over populated areas of the Northern Hemisphere, Arndt said. ;The Arctic air has really turned itself loose on us.;阿恩特说:“我们看到的只是北极空气在北半球人口密集地区的一次大爆发,北极空气真的向我们发威了。”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 confined.在大气中,大股大气环流由西向东在北极和热带地区之间移动。这股气流就像一个屏障,把北极空气给禁锢了起来。But recently, this air flow has become bent into a pronounced zigzag pattern, meandering 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.不过,最近这股气流明显呈“Z”形走势,向南北方向蔓延。如果你居住的地区有南上气流经过,那么天气将会变暖。事实上,华盛顿州和阿拉斯加州上周的温度都创下历史新高。But in the eastern ed States, like some other unlucky parts of the globe, Arctic air is swooping down from the north. And that#39;s how you get a temperature of 3 degrees in Beijing, a ing of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain, where a member of Parliament who said the snow ;clearly indicates a cooling trend; was jeered by colleagues.然而,和其他不太幸运的地区一样,美国东部正遭遇一股从北方呼啸而下的冷空气。这就是为什么北京的气温会低至3度,挪威大陆的气温降到零下42度,英国部分地区会有厚达18英寸的积雪。英国某议员说大雪“表明气候有变冷的趋势”,结果遭到同事的讥笑。The zigzag pattern arises naturally from time to time, but it is not clear why it#39;s so strong right now, said Michelle L#39;Heureux, a meteorologist at the Climate Prediction Center of the National Oceanic and Atmospheric Administration. The center says the pattern should begin to weaken in a week or two.国家海洋和大气气候预测中心的气象学家米歇尔#8226;拉赫茹克斯说,这种“Z”形走势不时出现,这很自然,但不清楚为什么现在会这么强劲。该中心说这一走势应该会在一两周后开始减弱。 /201206/185739
