Practice 1　　A symbol of abundance to the rest of the world, the Amazon is experiencing a crisis of overfishing. As stocks of the most popular species diminish to worrisome levels, tensions are growing between subsistence fishermen and their commercial rivals, who are eager to enrich their bottom line and satisfy the growing appetite for fish of city-dwellers in Brazil and abroad.　　In response, peasants up and down the Amazon, here in Brazil and in neighboring countries like Peru, are forming cooperatives to control fish catches and restock their rivers and lakes. But that effort, increasingly successful, has only encouraged the commercial fishing operations, as well as some of the peasants' less disciplined neighbors, to step up their depredations.　　“The industrial fishing boats, the big 20- to 30-ton vessels, they have a different mentality than us artisanal fishermen, who have learned to take the protection of the environment into account,” said the president of the local fishermen's union. “They want to sweep everything up with their dragnets and then move on, benefiting from our work and sacrifice and leaving us with nothing.”

3.Text 3When prehistoric man arrived in new parts of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.Dr. Worm acknowledges that the figures are conservative. One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now.Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline.” The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.31. The extinction of large prehistoric animals is noted to suggest that ________.[A] large animal were vulnerable to the changing environment[B] small species survived as large animals disappeared[C] large sea animals may face the same threat today[D] slow-growing fish outlive fast-growing ones

  • 第2题：

    The loss of biological diversity has become most spectacularly noticeable in extinction or decline of populations of large and well-known animals.Many animal species have become extinct since the 1700’s, among them the California grizzly bear, the dodo, and the passenger pigeon.Hundreds of other animal species are threatened.In North America, endangered species include the black-footed ferret, the California condor, the desert tortoise, and the whooping crane.

    Most species in danger of extinction anywhere in the world are suffering from the intrusion (侵入) of human beings.The Asian elephant, for example, has become an endangered species due to the expansion of the human population throughout its range in southern Asia.In Africa, the African elephants are being killed off for their tusks.Monkeys and other primates throughout the world are threatened by hunting, capture for medical use, and the destruction of their habitats.And the rhinoceroses, lions, and other large mammals of the African savanna (grassy plains with scattered trees) compete for land and life with some of the most rapidly growing human populations in the world.

    The loss of biological diversity is most severe, however, in the tropical rain forests.The forests of the tropics are particularly vulnerable to disturbance because the soils have a low capacity for retaining nutrients.Most of the forests’ nutrient elements are held in the tissues of plants.When loggers and farmers destroy existing plant cover, the nutrients are washed from the land into streams, and the land itself becomes less able to support life.Destruction of these forests destroys the habitat of hundreds, sometimes thousands, of species from such creatures as the howler monkey and indigo macaw, to less visible species of plants, insects, and microbes, many of which are not yet known to science.

    1.The author points out that species extinction ().

    A.is most noticeable in North America

    B.is mainly taking place among large animals

    C.quickened with industrialization of the society

    D.never took place before the 1700’s

    2.Which of the following is NOT mentioned with regard to human intrusion?

    A.Elephants are killed off for their tusks

    B.Some primates are hunted for medical use

    C.Growing human population results in the competition for land and life among animals

    D.Men live increasingly on animals as their source of food.

    3.The chief cause of the gradual disappearance of biological diversity is ().

    A.human cruelty

    B.human interference

    C.the increase of human population

    D.the disappearance of the forests

    4.In tropical forests，().

    A.animals live a hard life due to competition

    B.a lot of species die out for lack of food

    C.rains constitute the major threat to species

    D.a greater number of animals are yet to be known

    5.It can be inferred that species extinction ().

    A.proceeds of a faster rate than noticeable

    B.is the worst among well-known animals

    C.is the most severe in Africa

    D.is chiefly due to competition among species

    Water一the Issue of This Century
    The world is running short of freshwater. Populations are growing bigger and thirstier （渴的）,with the result that freshwater is becoming increasingly scarce（缺乏）.Half the world's wetlands have disappeared during the last century,while estimates suggest that wa- ter use will rise by 50% in the next 30 years.
    The World Bank report estimates that as much as half of the world's population,concentrated in Africa,the Middle East and south Asia,will face“severe water shortages”by 2025.Local water conflicts and the loss of freshwater ecosystems appear large in some re- gions.
    A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits, and half the world's coral reefs（珊瑚礁）may perish in 100 years. Almost 60% of coral reefs and 34% of fish species are at risk from human activities,the Bank says.
    The report concludes that there is ample evidence to justify immediate and coordinated action to safeguard supplies and use water more efficiently.
    Fresh water consumption is rising quickly,and the availability of water in some regions is likely to become one of the most pressing issues of the 21st century.
    A third of the world's popu1ation一around two billion people一live in countries that are experiencing moderate to high water shortages.That proportion could rise to half or more in the next 30 years unless institutions（制度）change to ensure better conservation and alloca- tion of water.
    China is one country where the portents（征兆）are gloomy. The most waterstressed country in East Asia,China is exploiting 44%of its usable water,a figure projected to rise to6O%by 2020.Primary withdrawal of water of more than 60%is widely considered by water experts to exceed the environmental carrying capacity of a river basin system. Although
    China's total use appears still to be reasonable,it has several basins that are severely stressed environmentally.
    Withdrawals exceed environmental limits in Afghanistan and Pakistan,and will exceed them in India by 2020.In the Middle East and North Africa,only Morocco has unexploited water resources.The rest have exceeded environmental limits and many are mining aquifers （蓄水层）一bodies of water-bearing rock一the report says.

    Most of the world's population may live within 100km of the sea in 2025.
    A: Right
    B: Wrong
    C: Not mentioned

    答案：A
    解析：
    题干意为“据估计，30年以后水的使用量将增加50%”。利用题干中的细节 信息词/短语water use, 50% , next 30 years作为定位线索，在短文第一段中寻找到相关句： The world is running short of fresh water. Populations are growing bigger and thirstier（渴 的）,with the result that freshwater is becoming increasingly scarce（缺乏）.Half the world's wetlands have disappeared during the last century,while estimates suggest that water use will rise by 50% in the next 30 years．相关句（带下划线的句子）意为“在上个世纪的100年里世界上一半的沼泽地已经消失了，而依据人们的估计来看，30年后水的使用量将增加50%”, 很明显题干陈述的意义与短文中的相关内容一致，因此题干陈述了正确的信息。所以答案为A。
    题干意为“大多数发达国家20年以后将面临水的短缺问题”。利用题干中 的细节信息词/短语most developed countries, water shortages, in 20 years作为定位线索， 结果发现most developed countries根本没有在短文中出现，短文中也没有具体提到发达国家水短缺的情况，因此题干陈述的信息是短文中未提及的信息。所以答案为C。
    题干意为“到了2025年，地球上大多数的人可能会生活在距离海洋100公 里的范围里”。利用题干中的细节信息短语most of the world's population, 100km of the sea, in 2025作为定位线索，这样在第三段中找到相关句：A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people（与题干中的most of the world's population呼应）may live within 100km of the sea in 2025 , putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits, and half the world's coral reefs（珊瑚礁）may perish in 100 years.Almost 60% of coral reefs and 34% of fish species are at risk from human activities, the Bank says．相关句（第三段第二句）提到“到2025年，世界上3/4的人将可能生活在距离海洋100公里的范围里”，显然题干陈述的意义与短文相关内容一致。所以答案为A。到目前为 止，在完成的3道题的答案里出现了2个A,1个C，剩下的4道题肯定至少会出现1-3个 B，因此如果考虑节约答题时间，剩下的4小题全选B，这样在该阅读理解题上就通过完成3 小题而直接拿到5小题的分数（即拿到5分！)
    题干意为“几乎所有的珊瑚礁都可能在10。年后消失”。利用题干中的细节 信息短语almost all coral reefs, in 100 years作为定位线索，这样在第三段中找到相关句：A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits,and half the world's coral reefs(珊瑚礁）may perish in 100 years.Almost 60% of coral reefs and 34% of fish species are at risk from human activities, the Bank says．相关句（第三段倒数第二句）意为“2/3的渔业开发已经处于可承受的边缘，甚至超出了可承受的范围，世界上一半的珊瑚礁可能会在100年后消失”。短文提到“一半的珊瑚礁”可能会在100年后消失，而不是“几乎所有的珊瑚礁”可能会在100年后消失，因此题干陈述的信息与短文内 容不一致。所以答案为B。
    题干意为“大西洋中的一些鱼类正处于危险的状况中”。利用题干中的细节 信息词/短语some species of fish, Atlantic, dangerously low levels作为定位线索，在第三段 中寻找到相关句：A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业） are exploited at or beyond their sustainable limits,and half the world's coral reefs（珊瑚礁）may perish in 100 years. Almost 60% of coral reefs and 34% of fish species are at risk from human activities, the Bank says．相关句（带下划线的句子）提到“世界银行说几乎有60%的珊瑚礁和34%的鱼 类因为人类的活动而处于危险的状况中”，这个句子陈述的是全世界鱼类的情况，至于在大西洋是否也是这样，该句中没有提到，依据该句意义也无法推断出大西洋地区鱼类的情况。短文中的其他句子没有再提及鱼类的情况，由此可判断出题干陈述的信息是短文中未提及的信 息。所以答案为C。
    题干意为“世界银行的报告意味着应该采取紧急行动来保护水资源的供 应”。利用题干中的细节信息词/短语the World Bank report, urgent action, water supplies 作为定位线索，在第四段中寻找到相关句：The report（指上文中提到的世界银行的报告） concludes that there is ample evidence to justify immediate and coordinated action to safe- guard supplies and use water more efficiently．第四段是一个独立成段句，该段意为“那份报告得出的结论是有大量的证据证明应该立刻采取协调一致的行动来保护水资源的供应，并更有效地使用水资源”。显然题干陈述的意义与短文中的相关意义一致，因此答案为A。
    题干意为“印度（现在）超过了水资源的环境使用极限”。利用题干中的细节 信息词/短语India , environmental limits , water use作为定位线索，在最后一段中寻找到相关句：Withdrawals（与上文中提到的withdrawal of water<水资源的使用>呼应）exceed environmental limits in Afghanistan and Pakistan,and will exceed them in India by 2020.In the

    1.How to evaluate students’ performance?
    【参考答案】
    Students may make some mistakes during their process of learning, but as for how to correct their mistakes, it is an art. Students in this age like being praised by teachers and do not want to be blamed for their mistakes. So, as a teacher, we must know to evaluate students’ performance artfully. No matter what their answers are, we must give them positive evaluations to encourage them. For example, we can say to them “good job” “well done” “you are a good listener” “you can do better next time” and so on to respond to their performance. If we correct their mistakes directly, they may lose hear in learning. So, we teachers must praise them more, and they may get more interested in our English class.
    2. In a writing lesson, which part do you think is the most important one and why?
    【参考答案】
    In a writing lesson, I think the most important part is the Presentation. Because the teacher should set a topic for the students. And show the correct way to search the material and let students know which kind of material is suitable for the certain topic. What’s more, if there is a certain structure in the writing lesson. The teacher also should explain the article structure in the presentation. With all above, the students can use their writing material to finish their writing task.

    Practice 1　　The greenhouse effect causes trouble by raising the temperature of the planet. The  1 rise is not very much，but the Earth’s ecosystem is very weak，and small changes can have large effects.　　It has been believed that this 2 of one degree will happen by the year 2025. This could probably  3 the North American corn belt, which produces much of the world’s grain， 4 to much higher food prices，and even less food for the Third World than they already have. However，it would also mean that some countries which are further north would be able to  5 crops they had never been able to before，although there is less land as you move north from the corn belt.　　The other serious worry is that rising sea levels from the melting of the polar ice could  6 flood many countries. A rise in sea levels of one meter，which many expels are  7 by the year 2100 (and some as soon as 2030)，would flood 15 percent of Egypt，and 12 percent of Bangladesh. The Maldives in the Indian Ocean would almost  8 disappear. Most of the countries which would suffer most from a rise in sea levels are the poor  9  states，so the islands in the Caribbean，South Pacific，Meditertgiiean and Indian Ocean have formed the Alliance of Small Island States，AOSIS，so they have a  10 voice in international politics and can make the richer developed world listen to their problems.[A] severely 　　　　 [B] damage　　　　　[C] island[D] critical　　　　　[E] grow 　　　　　 [F] mainland[G] louder 　　　　　 [H] predicting 　　 [I] rise[J] completely 　　　 [K] geometry 　　　 [L] actual[M] extending 　　　　[N] 1eading 　　　　[O] develop

    正确答案： 1.L 该处应填入形容词。根据后半句句意知道虽然温度变化的幅度很小,但还是会有很大的影响,因此可推知前半句说明的是实际的变化很小,由此可确定给定词中的actual正确,意为“实际的”。
    2.I 该处应填入名词。由this的指示作用可知此处所讲的内容上文有所提及,再根据空白处后的degree可推知此处填入的单词与温度有关,因此可确定rise为本题答案。
    3.B 该处应填入动词原形。上段说到温度上升会给生态带来不好的影响,故此处填入的单词应带有负面意义,所以可确定给定词中的damage正确。
    4.N 该处应填入能与to搭配的动词现在分词形式。这句话讲的是温度上升所带来的不利影响,因此可确定给定词中的leading正确,lead to意为“导致”。
    5.E 该处应填入动词原形。由句首的however可推知,温度上升会给一些地区带来不利影响,但也会使别的地区受益,因此可确定给定词中的grow正确,表明一些国家由于温度升高可以种植一些原本不能种植的作物。
    6.A 该处应填入副词。根据下文提到的数据可以确定给定词中的severely符合题意。
    7.H 该处应填入动词的现在分词形式。根据后文的by the year 2100可推知此处应表示预测未来的情况,故可确定给定词中的predicting一词正确,意为“预测”。
    8.J 该处应填入副词。本句讲的是马尔代夫的情况,由almost…disappear可推知所给定词中的completely正确,说明马尔代夫可能会完全消失。
    9.C 该处应填入修饰states的形容词或名词。这句话说明贫穷的岛国受到海平面上升的影响最大,再根据后半句出现的islands可确定给定词中中的island为本题答案。
    10.G 该处应填入修饰voice的形容词。本句意为岛国形成联盟让发达国家聆听他们的声音,即增强自己的影响力和声音,故可确定给定词中的louder正确。

    问答题
    Practice 2　　Until recently, scientists knew little about life in the deep sea, nor had they reason to believe that it was being threatened. Now, with the benefit of technology that allows for deeper exploration, researchers have uncovered a remarkable array of species inhabiting the ocean floor at depths of more than 660 feet, or about 200 meters. At the same time, however, technology has also enabled fishermen to reach far deeper than ever before, into areas where bottom trawls can destroy in minutes what has taken nature hundreds and in some cases thousands of years to build.　　Many of the world's coral species, for example, are found at depths of more than 200 meters. It is also estimated that roughly half of the world's highest seamounts - areas that rise from the ocean floor and are particularly rich in marine life - are also found in the deep ocean.　　These deep sea ecosystems provide shelter, spawning and breeding areas for fish and other creatures, as well as protection from strong currents and predators. Moreover, they are believed to harbor some of the most extensive reservoirs of life on earth, with estimates ranging from 500,000 to 100 million species inhabiting these largely unexplored and highly fragile ecosystems.

    前不久,科学家们对深海生物还知之甚少,也不太相信它们正受到威胁。现在,随着深海探测技术的发展,研究人员发现660多英尺,即200米深的海底生存着大量多种多样的物种。但与此同时,渔业人员也可以依靠技术到达以前更深的地方,进行海底拖网捕捞,而此种深海捕捞则可在几分钟内就把大自然几百年乃至几千年的一切毁灭。
    例如,世界上的许多种珊瑚在二百多米深的海底才能找到。此外,据估计世界上一些最高的海底山约有一半位于深海海底。这些海底隆起的地方,海洋生物特别丰富。
    这些深海生态系统为鱼类和其他生物提供生存、产卵、繁殖的场所,保护它们免遭大海流和猎食者的侵袭。此外,据信这些深海生态系统蕴藏着世界上最丰富的生命宝库,估计有五十万至一亿种生物生活在这些大体上未经勘探极脆弱的生态系统中。

    Water一the Issue of This Century
    The world is running short of freshwater. Populations are growing bigger and thirstier （渴的）,with the result that freshwater is becoming increasingly scarce（缺乏）.Half the world's wetlands have disappeared during the last century,while estimates suggest that wa- ter use will rise by 50% in the next 30 years.
    The World Bank report estimates that as much as half of the world's population,concentrated in Africa,the Middle East and south Asia,will face“severe water shortages”by 2025.Local water conflicts and the loss of freshwater ecosystems appear large in some re- gions.
    A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits, and half the world's coral reefs（珊瑚礁）may perish in 100 years. Almost 60% of coral reefs and 34% of fish species are at risk from human activities,the Bank says.
    The report concludes that there is ample evidence to justify immediate and coordinated action to safeguard supplies and use water more efficiently.
    Fresh water consumption is rising quickly,and the availability of water in some regions is likely to become one of the most pressing issues of the 21st century.
    A third of the world's popu1ation一around two billion people一live in countries that are experiencing moderate to high water shortages.That proportion could rise to half or more in the next 30 years unless institutions（制度）change to ensure better conservation and alloca- tion of water.
    China is one country where the portents（征兆）are gloomy. The most waterstressed country in East Asia,China is exploiting 44%of its usable water,a figure projected to rise to6O%by 2020.Primary withdrawal of water of more than 60%is widely considered by water experts to exceed the environmental carrying capacity of a river basin system. Although
    China's total use appears still to be reasonable,it has several basins that are severely stressed environmentally.
    Withdrawals exceed environmental limits in Afghanistan and Pakistan,and will exceed them in India by 2020.In the Middle East and North Africa,only Morocco has unexploited water resources.The rest have exceeded environmental limits and many are mining aquifers （蓄水层）一bodies of water-bearing rock一the report says.

    Some species of fish in the Atlantic are at dangerously low levels.
    A: Right
    B: Wrong
    C: Not mentioned

    答案：C
    解析：
    题干意为“据估计，30年以后水的使用量将增加50%”。利用题干中的细节 信息词/短语water use, 50% , next 30 years作为定位线索，在短文第一段中寻找到相关句： The world is running short of fresh water. Populations are growing bigger and thirstier（渴 的）,with the result that freshwater is becoming increasingly scarce（缺乏）.Half the world's wetlands have disappeared during the last century,while estimates suggest that water use will rise by 50% in the next 30 years．相关句（带下划线的句子）意为“在上个世纪的100年里世界上一半的沼泽地已经消失了，而依据人们的估计来看，30年后水的使用量将增加50%”, 很明显题干陈述的意义与短文中的相关内容一致，因此题干陈述了正确的信息。所以答案为A。
    题干意为“大多数发达国家20年以后将面临水的短缺问题”。利用题干中 的细节信息词/短语most developed countries, water shortages, in 20 years作为定位线索， 结果发现most developed countries根本没有在短文中出现，短文中也没有具体提到发达国家水短缺的情况，因此题干陈述的信息是短文中未提及的信息。所以答案为C。
    题干意为“到了2025年，地球上大多数的人可能会生活在距离海洋100公 里的范围里”。利用题干中的细节信息短语most of the world's population, 100km of the sea, in 2025作为定位线索，这样在第三段中找到相关句：A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people（与题干中的most of the world's population呼应）may live within 100km of the sea in 2025 , putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits, and half the world's coral reefs（珊瑚礁）may perish in 100 years.Almost 60% of coral reefs and 34% of fish species are at risk from human activities, the Bank says．相关句（第三段第二句）提到“到2025年，世界上3/4的人将可能生活在距离海洋100公里的范围里”，显然题干陈述的意义与短文相关内容一致。所以答案为A。到目前为 止，在完成的3道题的答案里出现了2个A,1个C，剩下的4道题肯定至少会出现1-3个 B，因此如果考虑节约答题时间，剩下的4小题全选B，这样在该阅读理解题上就通过完成3 小题而直接拿到5小题的分数（即拿到5分！)
    题干意为“几乎所有的珊瑚礁都可能在10。年后消失”。利用题干中的细节 信息短语almost all coral reefs, in 100 years作为定位线索，这样在第三段中找到相关句：A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits,and half the world's coral reefs(珊瑚礁）may perish in 100 years.Almost 60% of coral reefs and 34% of fish species are at risk from human activities, the Bank says．相关句（第三段倒数第二句）意为“2/3的渔业开发已经处于可承受的边缘，甚至超出了可承受的范围，世界上一半的珊瑚礁可能会在100年后消失”。短文提到“一半的珊瑚礁”可能会在100年后消失，而不是“几乎所有的珊瑚礁”可能会在100年后消失，因此题干陈述的信息与短文内 容不一致。所以答案为B。
    题干意为“大西洋中的一些鱼类正处于危险的状况中”。利用题干中的细节 信息词/短语some species of fish, Atlantic, dangerously low levels作为定位线索，在第三段 中寻找到相关句：A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业） are exploited at or beyond their sustainable limits,and half the world's coral reefs（珊瑚礁）may perish in 100 years. Almost 60% of coral reefs and 34% of fish species are at risk from human activities, the Bank says．相关句（带下划线的句子）提到“世界银行说几乎有60%的珊瑚礁和34%的鱼 类因为人类的活动而处于危险的状况中”，这个句子陈述的是全世界鱼类的情况，至于在大西洋是否也是这样，该句中没有提到，依据该句意义也无法推断出大西洋地区鱼类的情况。短文中的其他句子没有再提及鱼类的情况，由此可判断出题干陈述的信息是短文中未提及的信 息。所以答案为C。
    题干意为“世界银行的报告意味着应该采取紧急行动来保护水资源的供 应”。利用题干中的细节信息词/短语the World Bank report, urgent action, water supplies 作为定位线索，在第四段中寻找到相关句：The report（指上文中提到的世界银行的报告） concludes that there is ample evidence to justify immediate and coordinated action to safe- guard supplies and use water more efficiently．第四段是一个独立成段句，该段意为“那份报告得出的结论是有大量的证据证明应该立刻采取协调一致的行动来保护水资源的供应，并更有效地使用水资源”。显然题干陈述的意义与短文中的相关意义一致，因此答案为A。
    题干意为“印度（现在）超过了水资源的环境使用极限”。利用题干中的细节 信息词/短语India , environmental limits , water use作为定位线索，在最后一段中寻找到相关句：Withdrawals（与上文中提到的withdrawal of water<水资源的使用>呼应）exceed environmental limits in Afghanistan and Pakistan,and will exceed them in India by 2020.In the

    Practice 1　　A symbol of abundance to the rest of the world, the Amazon is experiencing a crisis of overfishing. As stocks of the most popular species diminish to worrisome levels, tensions are growing between subsistence fishermen and their commercial rivals, who are eager to enrich their bottom line and satisfy the growing appetite for fish of city-dwellers in Brazil and abroad.　　In response, peasants up and down the Amazon, here in Brazil and in neighboring countries like Peru, are forming cooperatives to control fish catches and restock their rivers and lakes. But that effort, increasingly successful, has only encouraged the commercial fishing operations, as well as some of the peasants' less disciplined neighbors, to step up their depredations.　　“The industrial fishing boats, the big 20- to 30-ton vessels, they have a different mentality than us artisanal fishermen, who have learned to take the protection of the environment into account,” said the president of the local fishermen's union. “They want to sweep everything up with their dragnets and then move on, benefiting from our work and sacrifice and leaving us with nothing.”

    正确答案： 【参考译文】
    亚马逊河在世界上是物产丰富的标志,到它现在正经受一场过量捕鱼的危机。随着人们最喜爱的各种鱼类数量日渐减少,到了令人担忧的地步,靠打鱼糊口的渔民和他们商业对手之间的紧张关系也日益加剧,因为这些对手一心想着装满自己的船舱,以满足巴西乃至国外城里人越来越大的吃鱼胃口。
    针对这种情况,亚马逊河沿岸的农民群众,在巴西境内也好,在秘鲁等邻国也好,纷纷成立合作社,以求控制捕鱼量,增加河湖中鱼的数量。但是,这方面的努力虽日见成效,却促使那些为商业目的而捕鱼的机构以及附近一些不大守规矩的农民加紧进行掠夺。
    “那些工业化的渔船,二、三十吨位的,他们的想法跟我们这些手工操作的渔民不一样,我们懂得考虑怎样保护环境,”当地的渔业工会主席说道。“他们想用拖网一网打尽,然后有上别处去打。我们出力,他们受益,弄得我们一无所有。”

In the international development (1) com____, the coronal wisdom has been that the billion people living in poor countries could never expect to (2) r____ the standard of living that most of the people in North America enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on. At the same time, we in the United States have continued to pursue super-affluence as though there were no limits (3)____ how much we could consume. We (4) m____ only 6 percent of the world’s people; yet we consume one third of the world’s resources.　　As long as the resources we consumed each year came primarily from (5) w____ our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, we will no longer be able to think in (6)____ of “our” resources and “their” resources, but only of (7) c____ resources.　　As Americans consume such a(n) (8)____(proportion) share of the world’s resources, we have to question whether or not we can continue our pursuit of super-affluence in a world of (9)____(scarce). We are now reaching the point at which we must carefully examine the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanced. But if you have a loaf of bread, then an additional crust of bread doesn’t make (10) d____. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. The prospect of a scarcity of, and competition in, the world’s resources requires that we re-examine the way in which we relate to the rest of the world.

    2.reach reach the standard of living达到生活标准。
    3.on limit后能接of,to,on/upon等介词,意思不相同。limit后接on,指对…施加限制,如:place a limit on the number of visitors限制参观的人数。limit后接of指…的限制,如:reach the limit of one’s patience达到了忍无可忍的地步。
