问答题The climate phenomenon that is being blamed for floods, hurricanes and early snow- storms deserves credit for invigorating plants and helping to control the pollutant linked to global warming, a new study shows. El Nino---the periodic warming of eastern Pacific Ocean waters--causes a burst of plant growth throughout the world, and this removes carbon dioxide from the atmosphere, researchers have found.Natural weather events, such as the brief warming caused by El Nino, have a much more dramatic effect than previously believed on how much carbon dioxide is absorbed by plants and how much of the gas is expelled by the soils, said David Schimel of the National Center for Atmospheric Research. He is co-author of a study to be published in the journal Science.Atmospheric carbon dioxide, or C02, has been increasing steadily for decades. This is thought to be caused by an expanded use of fossil fuels and by toppling of tropical forests. Scientists have linked the CO2 rise to global warming, a phenomenon known as the green- house effect. Nations of the world now are drawing up plans to reduce fossil-fuel burning in hopes of reducing greenhouse gases in the atmosphere.

问答题上午八时，丰城轮徐徐驶入日本东京湾，我兴奋地登上了驾驶台顶，凭栏远眺。我是第一次出海远航，当日本最大的国际贸易港横滨即将出现在眼前时，怎能不激动呢不一会，一位60多岁的日本引水员登上我轮。他彬彬有礼地向方船长鞠了一个躬，用流利的汉语说：“为了表示对中国人民的友好，我港方把山下码头一至十号泊位正式划为中国船舶优先停泊处。”他把“中国”两字说的特别有力。船长热情地伸出双手，微笑着说：“谢谢!”在这一瞬间，我真正理解了“中国”这两个字的含义，感觉到了她的力量。祖国强大，我们才能在国外受到如此的热情接待。后来，方船长又告诉我，在日本的许多港口都有专门的中国船舶优先停泊处，而且总是热情迎送。尽管远离祖国，但是我们始终感到有伟大的祖国作坚强后盾。我们的航向永远朝着祖国。
