题文
阅读理解 The need to feed a growing population is putting much pressure on the world's supply of water.With97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water
needs careful management, especially in agr
iculture.Although the idea o
f a water shortage(短缺)seems
strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural
industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs
of water redistribution(重新分配)are very high.Not only is there the cost of the engineering itself, but
there is also an environmental cost to be considered.Where valleys(山谷)are flooded to create dams,
houses are lost and wildlife homes destroyed.Besides, water may flow easily through pipes to fields, but
it cannot be transported from one side of the world to the other.Each country must therefore rely on the
management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overus
e of irrigation water has resulted in a 25% reduction of the water stores.
In the Central Valley area of southwestern USA, a huge water engineering project provided water for
farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of
irrigation water from underground reserves.Because there is no rainfall in these areas, s
uch reserves can
only decrease, and it is believed that fifty years of pumping will see them run dry.
1. From the first two paragraphs we learn that________.
A. much of the world's water is available for use
B. people in high rainfall countries feel lucky
C. the costs of water redistribution should be considered
D. water can be easily carried through pipes across the world
2. Which of the following is true?
A. The water stores in Texas have been reduced by 75%.
B. Most industries in the world suffer from water shortages.
C. The underground water in Saudi Arabia might run out in 50 years.
D. Good management of water use resulted from the project in the Central Valley.
3. What is most likely to be discussed in the paragraph that follows?
A. Steps to improving water use management.
B. Ways to reduce the costs of building dams.
C. Measures to deal with worldwide water shortages.
D. Approaches to handling the pressure on water supply.
4. The text is mainly about________.
A. water supply and increasing population
B. water use management and agriculture
C. water redistribution and wildlife protection
D. water shortages and environmental protection 题型：未知难度：其他题型

考点
据考高分专家说，试题“阅读理解 The need t.....”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。
