Practice 5 Water is essential for life. Yet many millions of people around the world face water shortages. Many millions of children die every year from water-borne diseases. And drought regularly afflicts some of the world’s poorest countries. The world needs to respond much better. We need to increase water efficiency, especially in agriculture. We need to free women and girls from the daily chore of hauling water. We must involve leaders of countries in decision-making on water management. We need to make sanitation a priority. This is where progress is lagging most. And we must show that water resources need not be a source of conflict. Instead, they can be a catalyst for cooperation. Significant gains have been made. But a major effort is still required. Our goal is to meet the internationally agreed targets for water and sanitation by 2015, and to build the foundation for further progress in the years beyond. This is an urgent matter of human development, and human dignity. Together, we can provide safe, clean water to the entire world’s people. The world’s water resources are our lifeline for survival, and [or sustainable development in the 21st century. Together, we must manage them better.

Water
Earth is like a big blue marble.From high above the Earth and from the moon,the planet gleams and shines.The blue water in the oceans and seas of the Earth makes a dramatic image.The white clouds above the Earth add beauty to the picture.Water is the source of this beauty and the source of life on Earth.It is the reason people can live on this planet. Water is everywhere.(46)_______.It is in the soil,the ground that grows the food.Water is in rock deep under the ground, in natural holding areas一in storage.In a real sense,water keeps Earth alive.
Nature has an unchanging amount of water. Nature has a perfect system for recycling water. (47)_____.It falls as rain.Then it goes to one of three places.It might sink slowly through the soil into the natural holding areas in the rock.(48)_______一by becoming vapor,or gas.It might run off into streams,rivers and oceans.By itself,nature can keep the balance and provide plenty of clean water for us.Nature recycles water.
However,people cause problems for this natural recycling system.Nature's recycling system can work well(49)________.Some ways that people upset nature are easy to understand.For example, dirty sewage（污水沟系统）water from homes and factories must not mix with drinking water. People get sick from drinking contaminated water. Sometimes water from factories goes into streams and rivers.It enters into the groundwater. It can flow into lakes too.This kind of contamination from industry(waste water from factories) can be dangerous for people.If water contains poisons and chemicals,it is poison.(50)________;some poisons kill people as well as birds and animals.Without knowing,people can upset nature's recycling system.
Lakes and rivers add beauty to the world. People enjoy water for entertainment purposes,too. People enjoy swimming and playing in the cool water of a lake in the summer. They like to ride on boats on rivers.Many people enjoy catching fish in the rivers.They fish for food and for sport.However,in some places,the water of the lakes and rivers is no longer safe.These rivers and lakes are contaminated.The fish are dying because of the chemicals from farms and factories.People cannot swim in the polluted water._________（49）
A:Poison makes people sick
B:It is in the air that people breathe
C:We can not live without water
D:Water is used again and again
E:only if people work with the system and not against it
F: It might disappear into the air quickly答案：E解析：文章前一句说水到处都存在，那么后一句应该跟此句有关系，而且下一句说“它存在土壤里”，因此选项B项“它在人们呼吸的空气里”是最合适的。
文章前一句说大自然有一个循环水的完美系统，那么后一句相关的选项只有D项“水可以一遍又一遍地反复利用”。
从本句的前后句看这是一个排比句式，三句话都是以it might开头，而后半句“变成蒸汽或水汽”更证明选项F是最合适的。
本句前一句讲人们会引起大自然循环体系的问题，那么空格里应该填入人们怎么做大自然的循环体系才能很好地运转。因此选项E“只有顺着这个系统，而不是对它造成破坏”是最佳选择。
本句前后句的关键词是“poison"，因此判断只有选项A“毒物使人生病” 最合适。 -

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.

问答题Practice 5 Never has there been a language quite like English. A bold statement, yet nevertheless true. Consider a few statistics. Today, one out of every seven people in the world use English in some way. More than half the world’s books are written in English; the majority of international telephone calls are made in English; 60% of the world’s radio programs are broadcast in English. English is even the working language of international air travel. For the first time in history, a single language has become dominant across a wide range of human activity, ranging from music, film and fine arts to the fields of business, diplomacy, science and technology.正确答案：

问答题Practice 10 The momentum is building ahead of next month’s G8 summit in Scotland where the leaders of the world’s richest nations will debate what they can do to help some of the world’s poorest. Africa is the priority and the politicians will discuss reducing the debt burden, ending trade regulations which put the continent’s economy at a disadvantage, and giving more aid. Mark Doyle, who’s reported from Africa for many years, looks at why aid is necessary, and why much of what’s been donated in the past has not worked. All around the edge of Africa-along the coastline, near the continents’ ports—are monuments to exploitation. On the island of Goree, for example, just off the coast of Senegal, there’s: the Slave House. This was the last place many Africans saw before being shipped off to a lifetime of slavery in American or, just as often, to death on the high seas. There are many more places like this dating from the three hundred and fifty years or so of the African slave trade. When people wonder why Africa is so poor, they need look no further for the start of an explanation.正确答案：

下个月在苏格兰举行的八国峰会上,世界上最富有国家的领导人将会讨论他们能为世界上最贫穷的国家做些什么。而在峰会召开前的一个月这种发展势头就有了征兆。非洲是优先考虑的对象,政客们会讨论减少非洲的债务负担,终止那些束缚非洲经济发展的贸易规则,同时给予更多的经济援助。马克·多伊勒在非洲从事新闻报道多年,他将探讨为什么经济援助是必须的,以及为什么以前的大部分资助没有起到作用。
沿着非洲的边界线——沿着海岸线,靠近大陆的港口——矗立着关于剥削的纪念碑。例如,离塞内加尔海岸线不远处的戈雷岛上就有一个奴隶交易所。这是很多被船只运往远方的非洲人离开故土时所看到的最后一个场景,他们很可能一辈子在美洲做奴隶,或是在途中葬身于汹涌的大海,而这种事情时常发生。
还有很多这样的地方,他们可以一直追溯到350年以前的非洲奴隶交易。当人们纳闷为什么非洲如此贫穷时,他们不再需要其他的解释。解析： 暂无解析 -

问答题Practice 4 The line of demarcation between the adult and the child world is drawn in many ways. For instance, many American parents may be totally divorced from the church, or entertain grave doubts about the existence of God, but they send their children to Sunday school and help them to pray. American parents struggle in a competitive world where sheer cunning and falsehood are often rewarded and respected, but they feed their children with nursery tales in which the morally good is pitted against the bad, and in the end the good inevitably is successful and the bad inevitably punished. When American parents are in serious domestic trouble, they maintain a front of sweetness and light before their children. Even if American parents suffer a major business or personal catastrophe, they feel obliged to turn to their children and say, “Honey, everything is going to be all right.” This American desire to keep the children’ s world separate from that of the adult is exemplified also by the practice of delaying transmission of the news to children when their parents have been killed in an accident. Thus, in summary, American parents face a world of reality while many of their children live in a near-ideal unreal realm where the rules of the parental world do not apply, are watered down, or are even reversed.正确答案： 【参考译文】
成人世界和儿童世界在许多方面泾渭分明。比如说,许多美国人可能从来不去教堂,或者对上帝是否存在十分怀疑,但是他们却会把孩子送到主日学校,教会他们祈祷。美国人生存的社会充满竞争,尔虞我诈才能名利双收,但是在他们教育孩子的幼儿故事里,在好人与坏人的斗争中最终却总是善有善报、恶有恶报。如果美国人出现严重的家庭危机,在孩子们面前,他们表面上却仍然是温柔可亲。即使工作、生活遭遇重大挫折,他们也认为有必要对孩子说:“宝贝儿,一切都会好起来的。”如果大人遭遇事故身亡,不会立刻把噩耗告诉孩子,这种做法也可以说明美国人希望让孩子的世界和成人的世界分离开来。因此,总的来说,美国人生活在现实的世界中,孩子则生活在一个几乎完美的天地里,这里成人世界的规则则不适用,淡化了,甚至完全相反。解析： 暂无解析 -

Passage Three
Questions 31 to 35 are based on the following passage.
One of the most exciting races ever run is now in progress between doctors fighting malaria(疟疾)and mosquitoes. According to the most recent counts 225 million people a year suffer attacks of malaria and more than two million die. Public health workers around the world are doing all t11ev can to destroy malaria before the mosquitoes that pass on the disease become resistant to the poisons now used against them. It's a race against time and against difficulties，with millions of lives in danger and the chances of winning not in man's favour.
Malaria，it is true，has been practically wiped out in thirteen countries. including the United States，and is under attack in many others. But it is equally true that in some parts of the world certain types of malaria-carrying mosquitoes have already learned to resist some of the sprays that formerly killed them. Other types of mosquitoes are not killed as quickly by present sprays as they once were.
The World Health Organization is helping national governments to get rid of malaria before resistance among the mosquito population becomes so great that new poisons will have to be found to replace those in use at present. Most of the countries in the world have started，or are planning，campaigns against mosquitoes. If the race against resistance is won by man，it is possible that ten years from now dais old evil will have disappeared completely from the America，perhaps from the world.
Malaria has been successfully got. rid of in______.
A. all countries
B. some countries
C. no countries
D. most countries

Many Children'S Deaths Preventable:WHO
Over five million children die each year from disease,infections and accidents related______(51)their environment although many of these deaths are largely preventable,says the World Health Organization.
On Monday,the WHO asked governments and citizens around the world to take action to cre-ate healthy______(52)for children as it celebrated World Health Day.
“The biggest threats to children's health lurk in the very______( 53)that should be safest-home,school and community,” said Dr. Gro Harlem Brundtland,director-general of the WHO at the day's launch in New Delhi,India.
“Every child has the right to______(54)up in a healthy home,school and community.
The future development of our children-and their world-depends on______(55)enjoying good health now.We have their future in our______(56).Now we must work more effectively together to______(57)the risks from the environment which our children face,”Brundtland said.
This year's theme,“Healthy Environments for Children”focuses on the many dangers ______(58)by children in and around the places where they live and play.
These include inadequate access to safe drinking______(59)and sanitation,insect- borne diseases,air pollution,chemical hazards and injuries from traffic,falls,burns and drownings.
Communities around the world organized events to promote awareness of children's health is-sues,______(60)included drawing contests for schoolchildren in Vietnam,street plays in In-dia,puppet shows in Namibia and professional lectures for policy makers in Germany and else-where.
Activities also took______(61)in cities across Canada on Monday,including Calgary, Montreal,Halifax and Ottawa.
Although children under five represent only 10 per cent of the world's population,they bear 40 per cent of the global disease______(62),says the WHO.And as much as one-third of the total burden of disease may be caused by environmental______(63).
World Health Day has been celebrated on April 7th______(64)1950 .Each year the WHO chooses a theme to highlight areas of particular concern.Last year's______(65),Move for Health,focused on promoting physical activity as part. of healthy living.65._________
A: concern
B: area
C: theme
D: celebration答案：C解析：本题的考点是固定搭配。此处表达的意思是“与环境相关的”,related to为固定搭配，意为“与……有关”。
从文章第一句可以看出，文章的重点，即世界卫生组织今年“世界卫生日”的主题，是创建健康的环境。
家庭、学校和社区应该是最安全的“地方”，可是，对儿童健康的最大威胁就存在于这些本该是最安全的地方。应选“地方”，而不是“机会”、“时间”或“岗位”。此句中的 “lurk”一词为不及物动词，意为“潜藏，潜在”。
本题的考点是与up搭配的词组的区分。此句的意思应该是“每个孩子都具有在健康家庭、学校和社区成长的权利”。grow up意为“成长，长大”,stay up意为“醒着不睡”,pick up意为“好转，改善；重新开始”,get up意为“站起；起床”。
此句谈及的是“我们的孩子们”，即“他们”。他们的未来取决于他们现在是否能享有良好的健康。
短语to have something in one's hand表示“掌握某事”。此句的意思是“他们的未来掌握在我们手中”。
本题的考点是名词risk的固定搭配。此句中“更加有效地工作”的目的应当是“减少我们的孩子们所面临的来自环境的危险”,“减少”用reduce。 run the risk ( of doing something）意为“冒自身危险做某事”；take a risk/risks意为“冒险做可能失败、有危险等的事”；二者都为固定词组。regard意为“注视；将某人（某事物）视为；留意”。
从上一句可以看出，此处应填“面临”一词。face做动词，可以有“面对，面向、对付，应付、面临”等意思。
从前后文可以看出，此处应填“水”这个词。drinking water意为“饮用水”。
根据空白处前面的逗号可以看，此处应填一个能引导非限制性定语从句的关系代词来代替events一词。
本题的考点是动词take的固定搭配。take place是固定搭配，意思是“发生”。take shape意为“成形；变得更有条理”,take orders from sb．意为“受命于某人，按某人之命做”。
从下一句可以看到，此处应选“burden”一词。短语disease burden的意思是“病症负担”。bear the burden是常用搭配。另外，后一句中的the total burden of disease也是一个值得注意的提示。
文章谈的是环境因素所造成的危害，所以此处应选“factors”一词。
从本句的时态——现在完成时可以推断全句的意思，即“自从1950年以来，每年的 4月7日都庆祝世界卫生日”。
前一句提到，“世界卫生组织每年都选择一个主题……”，此空白后面的短语首字母大写，显然代表主题，故应选“theme”。 -

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.India exceeds environmental limits for water use.
A: Right
B: Wrong
C: Not mentioned答案：B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。

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.

What We Take From and Give to the Sea
As long as we have been on earth,we have used the sea around us.We take things from the ocean,and we give to it.
We take fishes from the ocean-millions of kilograms of fish,every year,to feed millions of people.______(46)We take minerals from the ocean.One way to get salt is to place seawater in a shallow basin and leave it until it evaporates.______(47) Much gold and silver drift dissolved in the waters of the sea,too.But the sea does not give them up by simple evaporation.
Other gifts from the sea are pearls,sponges and seaweed.Pearls become jewelry.______(48)
Seaweed becomes food of many kinds-even candy,and ice cream-as well as medicine.Believe it or not,fresh water is another gift from the sea.We cannot drink ocean water.______(49)
But ocean water becomes fresh water when the salts are removed.In the future,we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food,fertilizer,minerals,water,and other gifts .What do we give the sea?
Garbage.______(50)Huge as it is,the ocean cannot hold all the water we pour into it. Dumping garbage into the ocean is killing off sea life.Yet as the world population grows,we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea,we might also destroy ourselves.Hopeful-ly,it is not too late.______(48)
A: Natural sponges become cleaning aids.
B: We pollute the ocean when we use it as a garbage dump.
C: The area of the sea is becoming smaller and smaller.
D: Along with salt,other minerals are left after evaporation.
E: We even use their bones for fertilizer.
F: Some of its contents may cause illness.答案：A解析：前面一句讲到：我们从大海里捕捞大量的鱼供人们食用，接着应讲“甚至连鱼的骨头也被用来做化肥”。even清楚地提示了这两句话的关系。
前面一句讲到：我们可以通过水的蒸发从海水中得到盐。通过常识可知，除了盐之外，水蒸发以后还会有别的矿物质留下来。
前面的内容讲到：除了矿物质外，大海还给了我们珍珠、海绵和海草。接着作者分别用一句话来说明每一样东西的用途。先讲了珍珠，最后讲的是海草，中间的一句肯定是讲海绵的用途了。
前一句话说海水不能喝，接下来很自然要解释为什么不能喝。
前面用garbage有力地回答了“我们给了大海什么”，这里是对回答的具体解释。 -

单选题Why do some people get sick after drinking the water from the river?ABecause the river is polluted
BBecause the river makes the earth more beautiful
CBecause the river can only offer water to animals
DBecause there are too many animals and plants in the river
正确答案： C解析：
题目问的是“为什么一些人在喝了河水之后生病了”，由The river的描述可知，树很难过，因为人类向河水中排放废物，这些废物杀死了许多喝我的河水的动物和植物。一些人喝了这种水也生病了，因此答案为A项，意思是“因为河流受到了污染”。 -

问答题Practice 5 Water is essential for life. Yet many millions of people around the world face water shortages. Many millions of children die every year from water-borne diseases. And drought regularly afflicts some of the world’s poorest countries. The world needs to respond much better. We need to increase water efficiency, especially in agriculture. We need to free women and girls from the daily chore of hauling water. We must involve leaders of countries in decision-making on water management. We need to make sanitation a priority. This is where progress is lagging most. And we must show that water resources need not be a source of conflict. Instead, they can be a catalyst for cooperation. Significant gains have been made. But a major effort is still required. Our goal is to meet the internationally agreed targets for water and sanitation by 2015, and to build the foundation for further progress in the years beyond. This is an urgent matter of human development, and human dignity. Together, we can provide safe, clean water to the entire world’s people. The world’s water resources are our lifeline for survival, and [or sustainable development in the 21st century. Together, we must manage them better.正确答案： 【参考译文】

第24题：
问答题Pollution is a problem because man, in an increasingly populated and industrialized world, is upsetting the environment in which he lives. Many scientists maintain that one of man’s greatest errors has been to equate growth with advancement. Now “growth” industries are being looked on with suspicion in case their side effects damage the environment and disrupt the relationship of different forms of life. The growing population makes increasing demands on the world’s fixed supply of air, water and land. This rise in population is accompanied by the desire of more and more people for a better standard of living. Thus still greater demands for electricity, water and goods result in an ever increasing amount of waste material to be disposed of.The problem has been causing increasing concern to living things and their environment. Many believe that man is not solving these problems quickly enough and that his selfish pursuit of possessions takes him past the point of no return before be fully appreciates the damage.正确答案：
污染已成为问题,因为在当今人口越来越多,社会越来越工业化的世界上,人类正在污染他们居住的环境。许多科学家认为人类最大的错误是把发展和进步等同起来。现在人们以怀疑的态度看待“发展性”的产业,因为它们的副作用会破坏环境,破坏各种生命之间的关系。人口的增长导致对世界上有限的空气、水和土地的需求不断增长。伴随着人口增长的是越来越多的人渴望更高的生活水平。于是对电、水和商品的更大需求必然造成有更多的废物要处理。这个问题已经引起人们对生物及其环境的日益关注。许多人认为,人类没有尽快地解决这一问题,却只顾谋求私利,以致于到了无可挽救的地步以后才充分认识到这种损害。解析： 暂无解析
