　　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.

　　参考答案：

　　1.[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.[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.[D]原文第6段中的Christmas和baby Jesus都表明厄尔尼诺的命名与基督教有关，因此选项A为本题答案。选项B中的religious researcher,选项C中的most usually happens around Christmas和选项D中的thefirst... in Spain均难以从原文得到证实。

　　4.[D]原文第7段第2句开头的分句表明厄尔尼诺现象的成因仍不明了，因此选项D为本题答案。选项A在文章开头有讨论到，选项B在第7段有讨论到，在讨论这两点信息的时候，作者并未提及对它们了解甚少，因此这两个选项不是本题答案;第7段首句有提及这种现象每隔三到五年出现，故选项C也不正确。

　　5.[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。
