英文原文阅读 | El Nino, an abnormal warming of surface ocean waters in the eastern tropical Pacific, is one part of what's called the Southern Oscillation. The Southern Oscillation is the see-saw pattern of reversing surface air pressure between the eastern and western tropical Pacific; when the surface pressure is high in the eastern tropical Pacific it is low in the western tropical Pacific, and vice-versa. Because the ocean warming and pressure reversals are, for the most part, simultaneous, scientists call this phenomenon the El Nino/Southern Oscillation or ENSO for short. South American fishermen have given this phenomenon the name El Nino, which is Spanish for "The Christ Child," because it comes about the time of the celebration of the birth of the Christ Child-Christmas. To really understand the effects of an El Nino event, compare the normal conditions of the Pacific region and then see what happens during El Nino below. Scientists do not really understand how El Nino forms. It is believed that El Nino may have contributed to the 1993 Mississippi and 1995 California floods, drought conditions in South America, Africa and Australia. It is also believed that El Nino contributed to the lack of serious storms such as hurricanes in the North Atlantic which spared states like Florida from serious storm related damage. Unfortunately not all El Nino's are the same nor does the atmosphere always react in the same way from one El Nino to another. This is why NASA's Earth scientists continue to take part in international efforts to understand El Nino events. Hopefully one day scientists will be able to provide sufficient warning so that we can be better prepared to deal with the damages and changes that El Nino causes in the weather. |

题型技巧分析 | 是非无判断题是雅思阅读考试的经典题型，虽然今年的题量相对减少，但是仍是复习备考时应关注的题型。 首先应该注意看清是TRUE还是YES, 本篇是TRUE /FALSE /NOT GIVEN 解题步骤： 1. 速读问题的句子，找出考点词（容易有问题的部分）。考点词：比较级，最高级，数据（时间），程度副词，特殊形容词，绝对化的词（only, most, each, any, every, the same as等） 2. 排除考点词，在余下的词中找定位词，去原文定位。 3. 重点考察考点词是否有提及，是否正确。 TRUE的原则是同义替换，至少有一组近义词。 FALSE是题目和原文截然相反，不可共存，通常有至少一组反义词。 NOT GIVEN是原文未提及，不做任何推断，尤其多考察题目的主语等名词在原文是否有提及。 |
