　　A massive pool of warm ocean water is causing changes in the atmosphere that could produce unusual weather around ihc world in the next few months. the US National Weather Service reported on Monday.

　　As a result of this phenomenon. known as El Nino, more rainfall than normal is likely this winter across some areas of the United States, with unusually warm or cold weather in other parts of the country.

　　Currently the phenomenon is marked by a warm pool of water along the equator extending from the International Date Line nearly to the coast of South America. That water is nearly 4. degrees Fahrenheit above normal. explained Vernon Kousky of the climate center.

　　This warm water "spreads almost a quarter of the way around the globe. So it's massive and it has an impact on our weather. It has a global influence... because it disturbs the atmosphere", said Dave Rodenhuis. director of the climate center.

　　"E1 Nino is probably the most important climate event beyond the annual cycle of seasons", he added.

　　Because the changes tended to be first noticed around Christmas, the phenomenon was given che name El Nino, which is Spanish for child, a term often used to refer to the baby Jesus.

　　The phenomenon occurs every three to five years, sometimes in a mild form and sometimes strongly affecting weather patterns worldwide. Details of its cause are not fully understood, but when it occurs. unusually warm air can be pumped into Canada. Alaska and the northern United States. At the same time, conditions tend to be wetter than normal along the US Southeast Coast and the Gulf of Mexico. And the Atlantic and Caribbean hurricane season tends to be milder than usual.

　　The strong El Nino of 1982-1983 was blamed for worsening the devastating drought in Africa, causing a series or severe winter storms to come ashore in California, spawning the first typhoon to strike French Polynesia m 75 years-followed by five more in Five months-deluging Peru and Ecuador with torrential rains and promoting the worst drought in two centuries in Australia.

　　Overall damage was estimated at between $2 billion and $8 billion by a United Nations analysis and the death toll topped l,500 worldwide.

　　1.对厄尔尼诺的最佳描述是______________。

　　A)异乎寻常的长时间段的热冷天气

　　B)世界各地异常的天气变化

　　C)由温暖海水引起的大气变化

　　D)海水和大气的升温

　　[C]第2段首句开头表明this phenomenon就是E1 Nino，而this phenomenon指的是前段提及的“大量温暖的海水引起大气变化”这一现象，由此可见，选顶C是对厄尔尼诺现象最恰当的描述。

　　2.温暖海水影响着全球的天气，因为________________。

　　A)它的温度大大超出标准

　　B)它在世界上占据了很大面积

　　C)它是最重要的气候事件之一

　　D) 它的影响从赤道开始

　　[B]原文第4段第2句开头的it's massive and_表明暖水对全球气候产生影响是因为it's massive，由此可见，选项B为本题答案。第3段末句提及水温比正常高了4度，但作者没有说明这4度是否too much above normal，因此选项A不正确;选项C没有在原文提及。

　　3.关于厄尔尼诺的命名，下列哪项是正确的?

　　B)名字是由一位宗教研究人员取的。

　　C)名字暗示了厄尔尼诺通常在圣诞节前后发生。

　　5.在文章最后两段，关于厄尔尼诺作者想要告诉我们的是__________。

　　A)联合国对厄尔尼诺的关心

　　B)对厄尔尼诺采取的应对措施

　　C)厄尔尼诺的强度

　　[C]从原文倒数第2段开头的was blamed for...和这两段的用词及数字可以知道，这两段主要陈述了厄尔尼诺现象对全球气候的破坏，即它的破坏力，选项C的intensity意为“强度，剧烈的程度”，与两段的主题内容最接近，因此为本题答案。
