题文

阅读理解。 Half of the world's population is affected by Asian monsoons (季风), but monsoons are difficult to predict. American rearchers have put together a 700-year record of the rainy asons, which is expected to provide guidance for experts making weather predictions Every year, moist (潮湿的) air mass,known as monsoon,produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south. According to Edward Cook, a weather expert at Columbia University in New York, the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much u. Therefore, he and a team of rearchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings, or circles, inside thousands of ancient trees in more than 300 places. Rainfall has a direct link to the growth and width of rings on some kinds of trees. The rearchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over ven centuries, beginning in the 1300s. Professor Cook says the tree-ring records show periods of wet and dry weather. "If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology that we developed in Asia provide us with a measure of monsoon variability." With all this information, rearchers say they can begin to improve computer climate models for predicting the behavior of monsoons. "There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cau extensive flooding." said Eugene Wahl, a scientist with America's National Oceanic and Atmospheric Administration. "So, to get a n of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science."1.What's the passage mainly about?A.

It is difficult for experts to predict Asian monsoons becau _______.A. it is hard to keep long-term climate records. B. they are formed under complex climate systems.C. they influence many nations.

The Monsoon Asia Drought Atlas has a monsoon record for about 1,300 years.C. The trees affected by monsoon grow fast if the monsoon is weak.D. The rainfall might be low although the monsoon is strong in monsoon-affected areas.4. According to Professor Cook, the rings of the trees _______.A. determine the regional climate.   B. have a great influence on the regional climate.C. offer people information about the regional climate. D. reflect all kinds of regional climate information.5. What do we know about the rearch according to Eugene Wahl?A. It is a great achievement in climate science.B.

考点

据考高分专家说，试题“阅读理解。 Half.....”主要考查你对 [日常生活类阅读 ]考点的理解。 日常生活类阅读

日常生活类阅读的概念：

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。

日常生活类阅读题答题技巧：

【题型说明】该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。 【备考提醒】为了保证较高准确率，建议同学们做好以下几点： 1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。 2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。 3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。 4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
