This is particularly troubling for countries with agricultural industries inareas dependent on irrigation (灌溉).In Texas, farmers' overuse 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, such reserves can only decrease,and it is believed that fifty years of pumping will see them run dry. 74. What is most likely to be discussed in the paragraph that follows? A. Steps to improving water use management.通读全文可知文章开篇点题,讲述了全球水资源紧缺,需要采取完善的管理措施,紧接着第二段和第三段讲述了因管理不当而造成或可能造成的严重后果,最后一段讲沙漠地区在发展农业时由缺少水源造成的困境。由此可推断文章接下来会讲述如何改善水资源管理,故选A项。
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. (三)词义猜测题 词义猜测型试题主要考查考生根据文章内容和所学知识推测词义的能力,也可能是推测单词、词组,也可能是生词或熟悉词(汇)的新义,或是一些词组的引申意义甚至整个句子。句意题涉及题材背景、句子结构、文章主旨、作者的观点态度等,因此,要求考生结合主旨、整合上下文信息作出猜测。命题者着重考查学生利用同义或反义关系、构词法、语法和语篇文脉结构等理解生词的能力,有些题目需要在较大的上下文范围和整个语篇理解的基础上才能作出推断,难度较高。 词义猜测题常见的命题形式有: 1.What does the underlined word mean“...” in the passage? 2.The word “...” refers to/ probably means ________. 3.The underlined word “...” in Paragraph... means ________. 4.What do you think the expression “________” stands for? 5.“________” as used in the passage can best be defined as ________. 6.Which of the following words can take the place of the word “...”? 7.The underlined word “...” is closest in meaning to ________. 8.The underlined word “...” could best be replaced by ________. 1.根据定义、解释和复述猜测词义 猜测生词的方法很多,其中一条是根据定义或解释来猜测其意义。这种情况下,生词往往出现在前面,定义或解释往往跟在生词的后面,由or或破折号引出。因此只要大家找准并正确理解生词的释义,生词的意义也就清楚了。复述也是一种解释方法,即换用不同的词语重新表达同一内容。复述部分可以是单词、短语,也可以是从句或者句子。
