In the decade（十年）of the 1970s, the United Nations organized several important meetings on the human environment to study a very serious problem．We humans are destroying the world around us．We must learn to protect them, or life will be very bad for our children and grandchildren．
There are several major aspects to this problem．
Population
Most problems of the environment come from population growth．In 1700 there were 635 million people in the world; in 1900 there were 1．6 billion; in 1950, 2．5 billion; and in 1980, 4．4 billion．In the year 2010 there will be 7．3 billion．More people need more water, more food, more wood, and more petroleum．
Distribution
Scientists say there is enough water in the world for everyone, but some countries have a lot of water and some have only a little．Some areas get all rain during one season．The rest of the year is dry．
Petroleum
We are using up the world’s petroleum．We use it in our cars and to heat our buildings in winter．Farmers use petrochemicals to make the soil rich．They use them to kill insects on those plants．These chemicals go into rivers and lakes and kill the fish there．Thousands of people also die from these chemicals every year．Chemicals also go into the air and pollute it．Winds carry this polluted air to other countries and other countries．
Poverty
Poor farmers use the same land over and over．The land needs a rest so it will be better next year．However, the farmer must have food every year．Poor people cut down trees for firewood．In some areas when the trees are gone, the land becomes desert．However, people need wood to cook their food now．Poor people cannot save the environment for the future．
We now have the information and the ability to solve these huge problems．However, this is not a problem for one country or one area of the world．It is a problem for all humans．The people and the nation of the world must work together to protect the world’s resources．No one controls the future, but we all help make it．
【小题1】According to the passage, our world is being destroyed mainly because ______．

Chinese reports say the country’s vast pool of cheap labor is getting smaller, which could hurt an economy that heavily depends on labor-intensive manufacturing.
The academy’s research shows that China’s rural labor surplus, the source of migrant workers for the country’s factories, is about 50 million people—far less than the previously estimated 150 to 200 million.
Jonathan Unger, director of the Contemporary China Center at the Australian National University, says fewer rural residents are willing to leave their farms today. This is partly because there are more employment opportunities in rural areas, and because agricultural prices have gone up.
“And at the same time taxes in the countryside, fees in the countryside have gone down because of new sets of government policies,” he explained. “So people are not eagerly forced in the way they were five, six years ago to leave the farm in order to earn enough money for their families.”
The Chinese Academy of Social Sciences says another reason for the reduced labor pool is the country’s population policy, which allows city residents to have just one child, and farmers up to two if the first one is a girl.
A UN study predicts that China’s workforce will reach its top in 2015 and then gradually drop. Some of China’s major manufacturing areas, such as Guangdong Province, already face labor shortages.
Some economists think these shortages are, at least for now, a regional rather than a national problem. Sun Mingchun, an economist with investment bank Lehman Brothers in Hong Kong, points out that there are still millions of people in China who can not find work.
57. According to the academy’s research, China’ rural labor surplus today is about _______.
A. 150 million      B. 50 million      C. 200 million      D. 175 million
58. The reason why many rural residents don’t leave their farms today is ________.
A. the farmers are older than before.
B. the farmers are lazier than before
C. the farmers have much more money
D. there are more employment opportunities and agricultural prices have gone up
59. Which of the following is TURE according to the passage?
A. A study of UN estimates China’s workforce will come to the top in 2015.
B. No a study shows millions of people can’t find work in China.
C. The country’s population policy isn’t a reason for the reduced labor.
D. Five years ago, few farmers left their homes to earn money for supporting their families.
60. According to some economists, the shortage of Chinese workforce __________.
A. is a national problem                     B. is a regional problem
C. is not a problem                         D. can be solved easily

The population conference in Brasilia has now ended. One of the aims of the conference was for countries from each continent to look back at past experiences and to learn from them for the future.
In Europe
Population problems are different in different parts of the world.  For example, in many European countries the population is getting older. The birth rate is very low because many young people have only one child or none at all. People are living longer, too. On average, men tire to 76 and women to 78. By 2050 around 25 % of the population of some European countries will be over 60 years old.
This change has happened very fast within two generations. If governments had expected this change, they would have encouraged people to prepare more for old age. At the moment many old people are very lonely and often very poor. If people had expected to live so long, they would probably have saved more money for their retirement.
In Africa
In Africa, the problems of the future will be very different. There, the population is doubling every 24 years. Many families continue to have large numbers of children to look after older people and to help on the land. However, better medical services have increased life expectancy and more children survive to become adults. Research shows that the size of the family is connected with the standard of women’s education. If more girls had gone to school in the last 20 years, family size in Africa would probably not have continued to be so big.
In Asia
In contrast, the problem in Asia is not just population growth but also overcrowding in many cities. Traditionally, most people have lived in the countryside, but within the next 25 years more than 65% will live in cities. If Asian countries had expected this kind of change 20 years ago, they would have tried to provide more work and better education in the countryside. This is starting to happen now, but it may be too late.
56. What is the cause of African population problem?
A. Low birth rate and increased life expectancy. B. More older people, more children.
C. People’s moving from the countryside to the cities.
D. Better medical services and increased life expectancy.
57. Which of the following is NOT true according to the passage?
A. In Europe it is normal to live to be 76 or more.
B. Medicine has changed population patterns.
C. Population problems are the same everywhere.
D. Many old people in Europe experience poverty.
58. What can be inferred from the passage?
A. Cities everywhere are becoming larger and larger.
B. Asian countries have tried to provide more work for people.
C. A lot of girls couldn’t go to school in Africa.
D. The older people in Europe are, the lonelier they will be.

Cittaslow has discovered China, and it is awarding a little village in Jiangsu the title of "slow city"
The bored teenagers of Gaochun are impatient with the leisurely pace of hometown life．For them there is no nightlife to speak of, no bright lights, no excitement and they cannot wait to grow up and leave for the urban attractions of the big cities．But it is this laid-back lifestyle that has attracted international attention．At least, a quiet village within Gaochun county has come under the spotlight．Yaxi village, population 20,000, is about to be designated China's first "slow city" by Cittaslow, the sustainable lifestyle movement that first surfaced in Italy 11 years ago．
At home, the residents at Yaxi are unfazed and pretty much unimpressed by the honor．To them, life has been like this for as long as they can remember．Here, growing old gracefully is natural．
Nobody living in this little county had heard of Cittaslow or the words "slow city" before this．
"The first time I heard the term was last July, when the vice-president of Cittaslow, Angelo Vassallo, visited Yaxi village," says Zuo Niansheng, the chief editor of local newspaper Gaochun Today．
"Vassallo was deeply impressed by this village's natural and cultural resources and said it perfectly fitted the requirements for a slow city," says Zuo．"That was how Yaxi became connected with Cittaslow．
The Slow City must also be committed to protect and maintain the natural environment as well as promote a sustainable way of development ?all of which are the current strategies adopted in Gaochun．"We've been doing this for years," adds Zuo．
Cittaslow was founded in Tuscany, Italy in 1999．It was a spin-off from the Slow Food movement which started, also in Italy, in 1986 as a protest against the first McDonald ' s opening near the Spanish Steps in Rome．The movement championed a return to healthy, nutritious home-grown, home -cooked food．
Slow Food has since expanded globally to more than 130 countries．Its mission has also broadened to include the promotion of sustainable foods and local small businesses, and the localization as opposed to globalization of food production．
Cittaslow is an expansion of the Slow Food movement, and it actively advocates a lifestyle that is sustainable, that will improve quality of life, and will preserve cultural and culinary （烹饪的）heritage．
【小题1】According the passage, Cittaslow is a（n） ____．

Britain and France are separated by the English Channel, a body of water that can be crossed in as few as 20 minutes. But the cultures of the two countries sometimes seem to be miles apart.
　　Last Thursday Britain and France celebrated the 100th anniversary(周年纪念) of the signing of a friendship agreement called the Entente Cordiality. The agreement—signed in London on April 8, 1904—marked a new beginning for the countries following centuries of wars and love-hate partnership.
　　But their relationship has been ups and downs over the past century. Just last year, there were fierce disagreements over the Iraq war—which British Prime Minister Tony Blair supported despite(不管, 尽管) French President Jacques Chirac speaking out against it. This discomfort is expressed in Blair and Chirac's body language at international meetings. While the French leader often greets German Chancellor Gerhard Schroeder with a hug (拥抱), Blair just receives a handshake.
However, some political experts say the war in Iraq could in fact have helped ties. “The British population was against war, ” said Francois Heisbourg, director of the Paris-based Foundation for Strategic Research(战略基金研究会). “So it could have actually helped bring the two sides closer. ”
　　The history of divisions(分割, 区分) may well be because of the very different ways in which the two sides see the world. “The French think Britain is not doing its best to become part of Europe by not introducing the single European currency(货币), ” said Geoff Hare, a former lecturer in French politics and language at Newcastle University in Britain. “France has spent the past 15 to 20 years making itself seen as part of the European Union. ”
　 But this doesn't stop 12 million Britons taking holidays in France each year. However,only 3 million French come in the opposite direction. Surveys show that most French people feel closer to the Germans than they do to the British. And the research carried out in Britain has found that only a third of the population believes the French can be trusted.Perhaps this bad feeling comes because the British dislike France's close relationship with Germany. Or because the French are not happy with Britain's close links with the US.
　　Whatever the answer is, as both sides celebrate 100 years of “doubtful friendship”, they are at least able to make jokes about each other. Here's one:What's the best thing about Britain's relationship with France? The English Channel.
1. For centuries, the relationship between England and France is______.
A. friendly

C. brotherly
D. a mixture of love and hate

B. harm
C. neither good nor harm
D. both good and harm
3. The British are not so friendly to ______ and the French are not so friendly to ______.
A. Germany;America
B. America;Germany
C. Germany;Germany too
D. America;America too
4. What does the last sentence mean?
A. As long as the English Channel exists, no further disagreement will form between France and Britain.
B. The English Channel can prevent anything unfriendly happening in both France and Britain.
C. France and Britain are near neighbors, and this will help balance the relationship between them.
D. The English Channel is the largest enemy between France and Britain.
5. What is the main idea of this passage?
A. The British differ greatly from the French in culture, origin and custom.
B. The British and The French are against each other because of the very different ways in which they see the world.
C. The celebration of the 100th anniversary of the signing of a friendship agreement mark-ed the mixture feeling of love and hatred over the last century between Britain and Franc-e.
D. The British dislike France's close relationship with Germany, while the French are not happy with Britain's close links with the US.
