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

第6题：

The world’s population continues to grow. There now are about 4 billion of us on earth. That could reach 6 billion by the end of the century and 11 billion in a further 75 years. Experts have long been concerned about such a growth. Where will we find the food, water, jobs, houses, school and health care for all these people?

A major new study shows that the situation may be changing. A large and rapid drop in the world’s birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.

Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from home instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population grow.

China is one of the nations that have made great progress in reducing its population growth. China has already cut its rate of population growth by about half since 1970.

Each Chinese family is now urged to have no more than one child. And the hope is to reach a zero population growth with the total number of births equaling the total number of deaths by the year 2000.

Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.

1. The world’s population could reach ____________.

A. 6 billion in 75 years

B. 11 billion in 2075

C. 11 billion by the end of this century

D. 600 million in 15 years

2. Which of the following is true?

A. The world’s birth rate is higher than ten years ago.

B. There has been a slower population growth in the past ten years.

C. Families are as large as before.

D. Birth control has been well practiced in all nations.

3. By the year 2000, the number of births and the number of deaths in China will _______.

A. be greatly different

B. drop a great deal

C. be equal

D. become much larger

4. According to the essay, China’s population control ________.

A. is not quite successful

B. should be considered a big success

C. is far from being successful

D. is a complete failure

5. It may happen in the future that the people who are working in Europe will have to pay much higher taxes because___________.

A. more and more children will be born

B. the number of retired people will become ever larger

C. fewer and fewer children will be born

D. they will be making a lot of money


答案：BBCBB

解析：译文

世界人口继续增长。现在地球上大约有40亿人。到本世纪末，这一数字可能会达到60亿，再过75年就会达到110亿。长期以来，专家们一直关注这种增长。我们在哪里能找到这些人的食物、水、工作、房子、学校和医疗保健？

一项新的重大研究表明，情况可能正在改变。在过去10年里，世界人口出生率急剧下降。现在的家庭一般比几年前小。发展中国家和工业国家都在发生这种情况。

研究人员说，他们发现了很多原因。越来越多的男人和女人等待结婚的时间更长，他们使用节育设备和方法来预防或推迟怀孕。越来越多的妇女去上学或者在离家不远的地方工作，而不是生孩子。越来越多的政府，特别是发展中国家，现在支持计划生育计划以减少人口增长。

中国是在减少人口增长方面取得重大进展的国家之一。自1970年以来，中国已经将人口增长率降低了大约一半。

现在每个中国家庭都被要求最多生一个孩子。希望到2000年人口零增长，出生总数等于死亡总数。

欧洲一些国家的出生人数已经少于死亡人数。专家说，这些国家未来可能面临严重的劳动力短缺。而那些正在工作的人可能面临更高的税收，以帮助支持越来越多的退休人员。

1、世界人口可能达到。

A、 75年60亿

B、 2075年110亿

C、 到本世纪末达到110亿美元

D、 15年6亿

2以下哪项是正确的？

A、 世界的出生率比十年前高。

B、 在过去的十年里人口增长缓慢。

C、 家庭和以前一样大。

D、 所有国家都实行节育。

三。到2000年，中国的出生人数和死亡人数将。

A、 大相径庭

B、 掉了很多东西

C、 平等

D、 变得更大

4；根据这篇文章，中国的人口控制。

A、 不是很成功

B、 应该算是大成功了

C、 远没有成功

D、 完全失败了

5将来，在欧洲工作的人可能要付更高的税，因为。

A、 会有越来越多的孩子出生

B、 退休人员的数量将越来越多

C、 孩子会越来越少

D、 他们会赚很多钱

1题：世界人口可能达到2075年110亿，文章第二行有显示

2题：在过去的十年里人口增长缓慢，文章第四行有显示

第8题：

What is the 'biggest city in the world? That is, (21) city has the largest population? This seems like (22) question to answer, but actually it isn't.

It's actually rather difficult to say which cities (23) the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large (24) area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.

The second reason that it is difficult to 25 the population of different cities is this: it is almost impossible to get (26) about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an (27) of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for (28) different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.

So we can say that these are our two (29) for comparing the populations of cities: one, it's difficult to determine the (30) of a city, and two, it is difficult to get accurate information.

B. which

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.

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。
