The shortage of clean drinking water is a major problem worldwide.The World Health Organization
says more than one billion people live in areas where fresh water resources are not available.The problem
is especially serious in Asia and the Pacific.A United Nations report says water availability in that area is
the second lowest in the world,after Africa.
Nearly half a billion people in Asia and the Pacific don"t have enough safe drinking water.The United
Nations report notes that the world"s poor countries are also the ones that use the most water for
agriculture.Agriculture uses about 80% of the water in the AsiaPacific area.There has also been an increase in water used for industry.India used three times more industrial water between 1999 and 2009 than in the past.
The shortage of clean drinking water around the world forces millions of people to drink unsafe water.
This leads to an increase in diseases like diarrhea (腹泻),the second leading cause of death in children.
Floods,pollution and climate change have made the water crisis more serious.
The Millennium Development Goals for 2015 plans a 50% decrease in the number of people without
safe drinking water.Scientists,governments and aid organizations around the world are increasing their
efforts to meet these goals.Still the United Nations says there is much work to be done.During this World Water Day celebration it called on other organizations to work together to fight against the water crisis.
The American researchers are designing a new technology for turning sea water into drinking water.The process uses electricity to help bring salt out from sea water to make it drinkable.The technology removed 99% of the salt and other harmful materials from sea water.So far the method has purified only small
amounts of water.But the researchers say it may someday be available as a personal water purifying
machine.
1. Which of the following has the lowest water availability in the world?
A. Asia.
B. Africa.
C. Europe.
D. Australia.
2. What"s the condition of water in poor countries?
A. The problem of wasting water is much serious.
B. Industry has been using most of the water.
C. Most of the water is used for watering farms.
D. The increasing population causes the water crisis.
3. From the passage we can know ________.
A. more people around the world are paying attention to the water crisis
B. World Water Day is celebrated every four years by the United Nations
C. more organizations are sending safe drinking water to the people in need
D. the water crisis will be solved with the effort of many organizations by 2015
4. What do we know about the new technology for turning sea water into drinking water?
A. It can take all the salt and harmful materials from sea water.
B. Scientists have made it widely used in daily life by now.

答案
举一反三
In a world with limited land,water and other natural resources,the harm from the traditional business
model is on the rise.Actually,the past decade has seen more and more forests disappearing and the globe
becoming increasingly warm.People now realize that this unhealthy situation must be changed,and that we must be able to develop in sustainable ways.That means growth with low carbon or development of
sustainable products.In other words,we should keep the earth healthy while using its supply of natural
resources.
Today,sustainable development is a popular trend in many countries.According to a recent study,the
global market for lowcarbon energy will become three times bigger over the next decade.China,for
example,has set its mind on leading that market,hoping to seize chances in the new round of the global
energy revolution.It is now trying hard to make full use of wind and solar energy,and is spending a huge
amount of money making electric cars and highspeed trains.In addition,we are also seeing great growth in
the global markets for sustainable products such as palm oil,which is produced without cutting down
valuable rainforest.In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets.First,they can set high targets for
reducing carbon emissions (排放) and targets for saving and reusing energy.Besides,stronger arrangement of public resources like forests can also help to speed up the development.Finally,governments can avoid
the huge expenses that are taking us in the wrong direction,and redirecting some of those expenses can
accelerate the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet.That is no small task,but it offers abundant new chances for sustainable product
industries.
1. The traditional business model is harmful because of all the following EXCEPT that ________.
A. it makes the world warmer
B. it consumes natural resources
C. it brings severe damage to forests
D. it makes growth hard to continue
2. What can we infer from Paragraph 2?
A. China lacks wind and solar energy.
B. China is the leader of the lowcarbon market.
C. Highspeed trains are a lowcarbon development.
D. Palm oil is made at the cost of valuable forests.
3. To full develop the lowcarbon markets,,government can ________.
A. cut public expenses
B. forbid carbon emission
C. develop public resources
D. encourage energy conservation
4. We can learn from the last paragraph that businesses have many chances to ________.
A. develop sustainable products
B. explore new natural resources
C. make full use of natural resources
D. deal with the major challenge
5. What is the main purpose of the passage?
A. To introduce a new business model.
B. To compare two business models.
C. To predict a change of the global market.
D. To advocate sustainable development.

Trees are useful to man in three i
mportant ways: they give him wood and other useful things, they give
him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most
important. Man wants to make money from trees, so he has cut them down in large numbers, only to find
that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil, make the rain in, and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
1. The most important points of trees to man is ________.
A. they help him to make money
B. they give him cool
C. they give him wood and other things
D. they help him to stop drought and floods
2. In many places forests slowly disappear because ________.
A. many trees have been cut down by man
B. new trees are not well looked after
C. man has not paid enough attention to planting trees
D. all the above
3. Land becomes desert after all trees are cut down because ________.
A. roots of trees break up the soil
B. there are too many rainfalls to make it
C. strong winds bring a lot of sand
D. no tree keeps the rain and protects the top-soil.
4. Which title best fits the passage?
A. Trees and Man
B. The Function of Tree Wood
C. How do People do with Trees?
D. The Usage of Tree Roots
Wind is one of our cleanest and richest power sources(来源) as well as one of the oldest. Evidence shows that windmills(风车)began to be used in ancient Iran back in the seventh century BC. They were first
introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of
using wind power.
For many centuries, people used windmills to grind(磨碎)wheat into flour or pump water from deep
underground. When electricity was discovered in the late 1800s. people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the1940s
when electricity was available to people in almost all areas of the United States, windmills were rarely
used.
During the 1970s,people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity .People also realized that the supply of coal and gas would not last
forever .Then, wind was rediscovered ,though it means higher costs. Today ,there is a global movement to supply more and more of our electricity through the use of wind.
B. have a history of more than 2,800 years
C. used to supply power to radio in remote areas
D. have rarely been used since electricity was discovered
B. Producing electricity
C. Grinding wheat into flour.
D. Pumping water from underground
B. it is one of the oldest power sources
C. it was cheaper to create energy from wind
D. the supply of coal and gas failed to meet needs
B. The design of wind power plants.
C. The worldwide movement to save energy
D. The global trend towards producing power from wind
of global warming. But scientists have warned that as the hole closes up in the next few decades,
temperatures on the continent could rise by around 3C on average, with melting ice contributing to a
global sea level increase of up to 1. 4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed,but the
other parts of the continent have, paradoxically, been cooling,resulting in a 10% increase in ice in the seas
around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica,
making much of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to
repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the
Antarctic will face the full impact of global warming. This means an increase in average air temperatures
of around 3? and a reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who
monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But
once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very
quickly. " Thinning ice sheets cause ice to break away from the continent and to melt even faster.
Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent
decades.
Johnson believes that international action to reduce global warming is required immediately or it may
be too late. "Everything is connected-Antarctica may be a long way away but it is an important part of
the Earth"s system," said Johnson. "It contains 90% of the world"s ice, 70% of the world"s fresh water
and that is enough, if it melts completely,to raise sea levels by 63 metres. "
Even in a worsecase situation scientists don"t expect the ice to entirely disappear,but predict that,
because of the melting ice sheets,average sea level rise will be around 1. 4 metres higher by the end of
the century.
B. approximately
C. contradictorily
D. apparently
B. It is causing the ice to melt faster.
C. It is making the effects of global warming in the region worse.
D. It is reducing the amount of water in Antarctica.
B. Warming sea water temperature.
C. Water pollution.
D. Growing ice sheets.
B. The average temperature has increased by 3 degree centigrade in recent decades.
C. Antarctica is currently experiencing the full effects of global warming.
D. Ten percent of Antarctica"s ice has already been lost.
B. Antarctica melting away
C. Action plan to save Antarctica
D. Let"s save the ozone layer
