Questions 61 to 65 are based on the following passage.

A bull grazes on dry wheat husks(Phi) in Logan, Kansas, one of the regions hit by therecord drought that has affected more than half of the U. S. and is expected to drive up foodprices.

Leadinu water scientists have issued one of the sternest warnings yet about global foodsupplies, saying that the world's population may have to switch almost completely to avegetarian diet over the next 40 years to avoid catastrophic shortages.

Adopting a vegetarian diet is one option to increase the amount of water available to growmore food in an increasingly climate-unstable world, the scientists said. Animal protein-richfood consumes 5 to 10 times more water than a vegetarian diet. One third of the world'sarable(适于耕种的) land is used to grow crops to feed animals. Other options to feed peopleinclude eliminating waste and increasing trade between countries in food surplus and those indeficit.

"900 million people already go hungry and 2 billion people are malnourished in spite of thefact that per capita food production continues to increase," they said. "With 70% of allavailable water being in agriculture, growing more food to feed an additional 2 billion peopleby 2050 will place greater pressure on available water and land. "

The report is being released at the start of the annual world water conference inStockholm, Sweden, where 2,500 politicians, UN bodies, non-governmental groups andresearchers from 120 countries meet to address global water supply problems.

Competition for water between food production and other uses will intensify pressure onessential resources, the scientists said. "The UN predicts that we must increase foodproduction by 70% by mid-century. This will place additional pressure on our 'alreadystressed water resources, at a time when we also need to allocate more water to satisfy globalenergy demand-- which is expected to rise 60% over the coming 30 years--and to generateelectricity for the 1.3 billion people currently without it," said the report.

Overeating, undernourishment and waste are all on the rise and increased food productionmay face future constraints from water scarcity.

"We will need a new recipe to feed the world in the future," said the report's editor, AndersJagerskog.

A separate report from the International Water Management Institute (IWMI) said the bestway for countries to protect millions of farmers from food insecurity in sub-Saharan Africa andsouth Asia was to help them invest in small pumps and simple technology, rather than todevelop expensive, large-scale irrigation projects.

"Farmem across the developing world are increasingly relying on and benefiting from small-scale,locally-relevant water solutions. These techniques could increase yields up to 300% andadd tens of billions of U. S. dollars to household revenues across sub-Saharan Africa and southAsia. " said Dr. Colin Chartres, the director general.

63.A)。本题考查对水资源科学家研究报告的理解。文中第四段第一句指出,科学家们说: “尽管人均粮食产量在持续增加,但仍有9亿人正在挨饿,20亿人营养不良,故答案为A)。

64.c)。本题考查科学家对于水资源供给的 态度。文中第六段第一句指出,报告中提到,“联合国预测,到本世纪中叶,我们必须增加70%的粮食产量。这会给本就紧张的水资源造成更大的压力”。第三句 指出,“与此同时,我们需要分配更多的水资源来满足世界能源的需求”,故答案为c)。





美国语言学家Driller (1978)根据词汇统计特征指出:如果我们认得25个最常见的英文单词,平均每页纸上的词我们会认得33%;如果认得135个常用词,则为50%;如果认得2500个,则为78%;如果认得5 000个,则为80%;一旦记得10000个,可达92%。可见,阅读能力的高低和词汇量的大小是分不开的,目前大部分学生的词汇量偏少, 这是影响阅读能力提高的主要因素。那么怎样才能提高学生的词汇量呢?

1. 构词记忆法

据估计,英语词汇有100万到120万,但大部分单词是由构词法构成的。构词法包括派生、合成和转化。在教学中,让学生掌握常用的前缀(un/dis/im/il /super.)、后缀( ly/ less/ ful/ ment…)的含义及用法,就可以根据已知词猜出它的派生词,从而达到扩大词汇的目的。如:前缀super 有超过,超越的含义,就可以猜出supermarket (超级市场)supernatural (超自然的)、 superman (超人)、superstar (超级明星)等词的含义。。

2. 联想记忆法

由一个词联想到和它有关或无关的词,如看到live vi 生活,联想到其他词性及用法,如,直播的、活的等词义。

3. 广泛阅读记忆法

“To read well, you need a strong vocabulary.. To build a strong vocabulary, you need to read well.” 这句名言道出了阅读和词汇量的关系。要有流利的阅读,就必须有丰富的词汇。大量的阅读可以丰富你的词汇。

(二) 牢固掌握语法知识

近年来的NMET阅读理解短文的句式结构趋向复杂,语法知识在阅读中的作用已经突显出来。如在阅读中遇到另人费解的长句、难句,就可以借助语法,对句子进行适当的分析,搞清各部分的关系,从而准确理解整句的意思。以Decision-thinking is not unlike poker-it often matters not only what you think, but also what others think you think and what you think they think you think.(NMET 2000) 为例。该句的29个词中包含了主语从句,宾语从句、并列句和破折号连接的附加说明等多种关系。其中并列句中又有复合句,复合句中又有并列句。只有把句子的成分一一理清,才能掌握其意思。


英语阅读能力的提高不仅需要一定的语言知识,还要有一定的文化背景知识和生活知识。例如在NMET2003的阅读理解A篇,该篇选材涉及地理,介绍了两座farthest/ most distant inhabited islands,一个为Guinness Book of Records 所认定的Tristan da Cunha;另一为复活岛(Easter Island)文章中出现了较多的专有名词,对于阅读经验不足的同学会形成干扰,而对于那些对Easter Day 等背景知识了解的同学,相对就会好些。另外在C篇中,出现了书刊号,如果熟悉这些,就会减少好多阅读困难。
