The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.

     An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the worst came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill(钻孔) deep in the side of a sandstone mountain. Temperatures in the area never rise above 0ºC. The seeds will be protected behind walls a meter thick and high-security door.

     The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will e from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0ºC. The cold weather would protect the seeds even if the air could not be replaced.

Mr. Fowler says the proposed structure will be the world’s safest gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first put forward the idea in the 1980s. But safety concerns delayed the plan. At that time, the Soviet Union was meeting in Rome of the Food and Agriculture Organization.

1.The project is meant to ______.

    A.increase the world’s food output in the future

    B.carry out some scientific experiments on plant genes

    C.build an exhibition centre of the world’s plant seeds

    D.protect crop seeds from dying out in case of possible disasters

2.Which of the following statements is TRUE according to the above passage?

    A.The government of Norway will perform the project alone.

    B.Seeds to be collected there were produced ten thousands years ago.

    C.Spitsbergen is chosen because it is free of the nuclear war forever.

    D.Temperature is a major consideration when choosing the storage place.

3.We can infer from the text that _______.

    A.Norway had meant to build the storage centre about 20 years before.   

B.The storage center will greatly promote world agriculture

    C.People will get newly-developed seeds from the center every year.

    D.There haven’t been any seed storage centres in the world before.

4.What is probably the best title of the passage?

    A.The Best Place to Store Seeds    

    B.Noah’s Ark(诺亚方舟)of Plant Seeds in Plan

    C.Concerns of World Food Supply  

    D.A New Way to Feed the World

Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Annan, the former United Nations secretary general.

The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition (营养不良) and heat-related health problems.

But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions.

Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries, were being seriously affected by climate change. It projected that the number would double by 2030.

Roger Pielke Jr., a political scientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum’s report was “a methodological embarrassment” because there was no way to distinguish deaths or economic losses related to human-driven global warming amid the much larger losses resulting from the growth in populations and economic development in vulnerable (易受伤害的) regions. Dr. Pielke said that “climate change is an important problem requiring our utmost (极度的) attention.” But the report, he said, “will harm the cause for action on both climate change and disasters because it is so deeply flawed (有瑕疵的).”

However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.

In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability(弱点) to climate hazards(危害)while still curbing (限制) the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.

1.What is the finding of the Global Humanitarian Forum?

A.Global temperatures affect the rate of economic development.

B.Rates of death from illnesses have risen due to global warming.

C.Malnutrition has caused serious health problems in poor countries.

D.Economic trends have to do with population and natural disasters.

2.  What do we learn about the Forum’s report from the passage?

A.It was challenged by some climate and risk experts.

B.It aroused a lot of interest in the scientific circles.

C.It was warmly received by environmentalists.

D.It caused a big stir in developing countries.

3. What does Dr. Pielke say about the Forum’s report?

A.Its statistics look embarrassing.

B.It is invalid in terms of methodology.

C.It deserves our closest attention.

D.Its conclusion is purposely exaggerated.

4.  What is Soren Andreasen’s view of the report?

A.Its conclusions are based on carefully collected data.

B.It is vulnerable to criticism if the statistics are closely examined.

C.It will give rise to heated discussions at the Copenhagen conference.

D.Its rough estimates are meant to draw the attention of world leaders.

5.  What does Kofi Annan say should be the focus of the Copenhagen conference?

A.How rich and poor regions can share responsibility in curbing global warming.

B.How human and economic losses from climate change can be reduced.

C.How emissions of heat-trapping gases can be reduced on a global scale.

D.How rich countries can better help poor regions reduce climate hazards.

As a boy, Charles Robert Darwin collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him.

     His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin’s interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin’s great life.

     As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.

     Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin’s great book, On the Origin of Species by Means of Natural Selection (《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.

    Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was still working on 17, April, 1882. He was dead two days later.

  In 1961, scientist set up gigantic, sensitive instruments to collect radio waves from the far reaches of space, hoping to discover in them some mathematical pattern indicating that the waves were sent out by other intelligent beings. The first attempt failed, but someday the experiment may succeed.

  What reason is there to think that we may actually detect intelligent life in outer space?To begin with, modern theories of the development of stars suggest that almost every star has some sort of family of planets. So any star like our own sun (and there are billions of such stars in the universe) is likely to have a planet situated at such a distance that it would receive about the same amount of radiation as the earth.

  Furthermore, such a planet would probably have the same general composition as our planet; so, allowing a billion years or two or three, there would be a very good chance for life to develop, if current theories of the origin of life are correct.

  But intelligent life?Life that has reached the stage of being able to send radio waves out into space in a deliberate pattern?Our own planet may have been in existence for five billion years and may have had life on it for two billion, but it is only in the last fifty years that intelligent life capable of sending radio waves into space has lived on earth. From this it might seem that even if there were no technical problems involved, the chance of receiving signals from any particular earth-type planet would be extremely small.

  This does not mean that intelligent life at our level does not exist somewhere. There are such an unimaginable number of stars that, even at such miserable possibility, it seems certain that there are millions of intelligent life forms scattered through space. The only trouble is, none may be within easy distance of us. Perhaps none ever will be; perhaps the distances that separate us from our fellow “creatures” of this universe will forever remain too great to be conquered. And yet it is conceivable that someday we may come across one of them or, frighteningly, one of them may come across us. What would they be like, these outside-the-earth creatures?

1.What point is the author making by stating that almost every star has some sort of family of planets?

  A. Sooner or later intelligent beings will be found on one of the stars.

  B. There must be one or two of the planets on which there are no intelligent beings.

  C. There are sufficient planets for there to be one that enjoys the same conditions as the earth does.

  D. One or two billion years later intelligent beings will generate on those planets.

2.What is the main topic of the passage?

  A. Some probable intelligent life forms on other planets.

  B. Various stages undergone by the intelligent life on other planets.

  C. Grounds for probable existence of intelligent life on other planets.

  D. The possibility of intelligent life existing on our planet.

3.Which of the following can be inferred from the passage?

A. An encounter is probable between people from the earth and intelligent beings from another planet.

B. Though the first attempt failed, scientists did discover the radio waves sent out by other intelligent beings.

C. Other intelligent beings were able to send our radio waves into space well before the last fifty years.

D. It is certain that there are millions of intelligent beings scattered in space but only too far away.

4.According to the author, what is the difference between “we may come across one of them” and “one of them may come across us”?

A. The earth would be dangerously disadvantaged if it is sought after by possibly much more developed creatures.

B. It would prove that there are too many outside-the-earth creatures if “one of them comes across us”.

C. The history of the development of the earth would be proved to be shorter than that of “them” if “they” come across us.

D. it would prove that the distance in between is not so great as we think if “we come across one of them” someday.

A new factory that turns used wine bottles into green sand could revolutionize the recycling industry and help to filter(过滤)the nation's drinking water.

For the last 100 years special high grade white sand quarried(开采)at Leighton Buzzard in Bedfordshire has been used to filter tap water to remove bacteria and impurities—but this may no longer be necessary.

The green sand has already been successfully tested by water companies and is being used in 50 swimming pools in Scotland to keep the water clean.

Backed by one million pounds from the European Union and the Department for Environment, Food and Rural Affairs(Defar),a company based in Scotland is building a factory to turn beverage bottles back into the sand from which they were made.

The idea is not only to avoid using up increasingly scarce sand in Scotland and avoid any further quarrying but also to solve a crisis in the recycles only 750 000 tones of it.

Howard Dryden, the scientist and managing director of the company has spent six years working on what he calls Active Filtration Meadia, or AFM, the recycled glass. He says he needs bottles that have already contained drinkable liquids to be sure that drinking water would not be polluted.

"The fact is that tests show that AFM does the job better than glass, it is easier to clean and reuse and has all sorts of properties that make it ideal for other applications, "he claimed. He also thinks the market will be able to take 250 000 tones of green sand a year. The plan is to build five or six factories in cites in UK where the bottles come from to cut down on transport.

The factory will be completed this month and is expected to go into full production on January 14 next year. Once it is providing a "regular" product, the government's drinking water inspectorate will be asked to perform tests and approve it for general use by water companies.

1.It may no longer be necessary to use high-grade white sand to keep water clean because_____.

A.there is no need to keep water clean

B.A new factory has been set up

C.The green sand has been used to keep the water clean

D.White sand is being use up

2.According to the passage ,the new idea can do the following except_____.

A. avoiding using up increasingly scarce sand

B. avoiding further quarrying of white sand

C. solving the crisis in the recycling industry

D. cutting down the cost on transport

3.Tests show that ______ in keeping the water clean.

A .AFM is more efficient than white sand

B.AFM is more efficient than glass

C. glass is more efficient than AFM

D. white sand is more efficient than green sand

4.The underlined word "Backed" in the third paragraph can best be replaced by"_____".

A. Allowed             B. Opposed

C. Supported            D. Forbidden

5.What would be the best title for the passage?

A. Revolution in the Recycling for the Industry.

B. Modern Technology an New Markets.

C. Revolution in Environmental Protection.

D. Unlocking the Benefits of Green Sand.
