    B
    (BBC News April 18) All flights in and out of the UK and several other European countries have been cancelled as ash from a volcanic eruption in Iceland moves south.
    Up to 4,000 flights are being cancelled with airspace closed in Norway, Sweden, Finland and Denmark among others.
    The UK’s air traffic control service (Nats) said no flights would be allowed in UK airspace until at least 07:00 BST on Friday for fear of engine damage.
    Safety group Eurocontrol said the problem could last for 48 hours.
    The volcano is still erupting and the wind direction is expected to continue bringing clouds into UK and European airspace for some time to come.
    The UK’s airspace restriction was the worst in living memory, a Nats spokesman said. Some 600,000 people are thought to have been affected.
    Nats suggested that the restrictions were unlikely to be lifted (解除) after 07:00, saying it was “very unlikely that the situation over England will improve in the foreseeable future”.
    Passengers were advised to contact their carriers before travelling.
    Transport Secretary Lord Adonis said he was “closely monitoring the situation” and would be meeting with key transport officials on Friday morning.
    Experts have warned that the tiny particles of rock, glass and sand contained in the ash cloud from the still-erupting volcano could be sufficient to jam aircraft engines.
    The Health Protection Agency said the ash from the eruption did not bring a significant risk to public health because of its high altitude.
    However, the British Lung Foundation has warned people with lung conditions to keep their medication (医疗护理) with them as a precautionary measure.
    These are some of the knock-on effects:
    ● Eurocontrol says Germany is monitoring the situation and considering partial airspace closures.
    ● The two main airports in Paris and many others in the north of France are closing. 
    ● There is severe disruption (崩溃) in France and Spain, where all northbound flights are cancelled. 
    ● Nats is due to make an announcement shortly as to the arrangements that will be in place
    through to 13:00 BST on Friday.
    ● British Airways offers refunds or an option to rebook after all its domestic flights are suspended.
    Flybe announces it has cancelled all flights up until 13:00 BST on Friday and more than 25 services due to run after that.
    British sports teams have been hit by travel problems after flights were grounded.
    60. What may passengers do on hearing the news according to the passage?
    A. They may cancel their international flights.
    B. They may contact the airlines before traveling.
    C. They may take measures to protect their lungs from the ash.
    D. They may stay indoors till the volcanic eruption dies down.
    61. Why have some European countries cancelled flights after the volcanic eruption?
    A. Because the volcanic ash may make passengers ill.
    B. Because people refuse to take the international flights.
    C. Because the volcanic ash may jam or damage the engine.
    D. Because the flights may be hit by the rocks from the eruption.
    62. Which of the following statements is true according to the passage?
    A. All the flights are likely to return to normal in 48 hours.
    B. British people had experienced a worse airspace restriction before that.
    C. Germany is monitoring the situation and considering closing all airspace. 
    D. The UK airspace restrictions are unlikely to be lifted in the foreseeable future.

    Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say．By shining a laser beam(激光束) on the tiny pieces of algae(海藻) floating in the water, the researchers said they hear sound waves that tell them the type and amount of pollution in the water．
    "It is a red light, telling us that something is beginning to go wrong with the quality of water," said Zvy Dubinsky, an aquatic biologist at Israel's Bar Ilan University．"Algae is the first thing to be affected by a change in water quality．"
    As water sources deteriorate worldwide, the testing of algae could be used to monitor water quality faster, more cheaply and more accurately than techniques now in use, Dubinsky said．The secret is to measure the rate of photosynthesis(光合作用) in the algae, meaning the plant's ability to transform light into energy．During photosynthesis, plants also release oxygen into the air．
    Dubinsky's technique is easy to perform because of the over-abundance of algae in the planet's water．Most of the oxygen in the atmosphere comes from algae．A prototype tester shoots a laser beam at water samples to stimulate photosynthesis in the algae．But not all of the laser's heat is used．
    Depending on the condition of the algae and the rate of photosynthesis, some of the heat is shot back into the water, creating sound waves, Dubinsky said．With a special underwater microphone, researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water．
    "Algae suffering from lead poisoning, like waste discharged from battery and paint manufacturing plants, will produce a different sound than those suffering from lack of iron or exposure to other toxins," said researcher Yulia Pinchasov．
    72．To study water quality, scientists choose algae mainly because       ．
    A．algae is most easily affected by pollution
    B．most oxygen is produced by algae
    C．the amount of algae is decreasing
    D．algae is a kind of plant floating in the water
    73．When Dubinsky studied water quality, he mainly focused on       ．
    A．the amount of laser used by algae
    B．the rate of photosynthesis in the algae
    C．the condition of the algae
    D．the heat of laser used by algae
    74．After the study, scientists proved that       ．
    A．the increase in population is caused by lack of water
    B．global warming causes water resources to reduce worldwide
    C．algae can show the type and amount of pollution in the water
    D．algae is dying out in the ocean around the world
    75．What would be the most suitable title for the passage?
    A．Water pollution is reduced with the growth of algae
    B．Pollution makes it hard for plants to make photosynthesis
    C．Water pollution affects the growth of marine plants
    D．Scientists listen to plants to find pollution

    BEIJING, Nov. 25, 2005（Reuters）— China’s home-grown human bird flu vaccine① is at least a year away from hitting the market but tests on humans have been approved by the government, head of the research drug company said on Friday.
    Development of the vaccine started last year after bird flu outbreaks in Thailand and Vietnam and animal trials have already been completed, said Yin Wei-dong, managing director of Sinovac Biotech.
    “It is not a virus that is spreading from human to human，so we are very optimistic②,” Yin told Reuters in an interview.
    The deadly H5N1 made its first known jump to humans in Hong Kong in 1997, killing six people. The virus appeared again in late 2003 and is known to have infected 130 people in several parts of Asia, killing 68 of them.
    “It is not decided yet when the human trials will begin. We just got approval on November 22 by the State Food and Drug Administration,” Yin said.
    Oregon, Nov. 26, 2005（AP）— The deadly strain of bird flu that appeared in Asia and has already spread to other parts of the world has not affected the Oregon poultry③ industry or consumers, according to Oregon State University researchers.
    There are many strains of bird flu that do not usually infect humans. But one strain, called H5N1, has jumped from chickens to humans and is blamed for more than 60 deaths in Asia.
    International disease control experts are worried about a worldwide outbreak of bird flu, raising concerns such as whether it is safe to eat poultry.
    But Oregon State University researchers say there is no proof that the virus can jump to humans by eating cooked poultry products.
    “Consumers needn’t be overly concerned about bird flu,” said Jim Hermes, OSU Extension Service poultry specialist. But he urged consumers to follow standard food safety practices in preparing poultry —including washing hands while preparing food, and proper cooking of poultry meat and eggs.
    He noted that a 2003 outbreak of bird virus caused much damage to commercial poultry operations in California but did not get into Oregon because of industry safeguards.
    Notes:
    vaccine  n. 疫苗
    optimistic  adj. 乐观的
    poultry  n. 家禽

    B．How the development of the bird flu vaccine is going on.
    C．How many people died of bird flu.
    D．What measures the government has taken to stop the spreading of bird flu.
    小题3:What does the underlined word “strains” probably mean?
    A．signs.B．symbols.C．kinds.D．diseases.
    小题4:What can we know from the second news report?
    A．Because of the safety guards, Oregon poultry industry didn’t suffer any loss in the 2003 outbreak of bird flu.
    B．People in Oregon are not concerned about bird flu.
    C．People will develop bird flu even if they eat well-cooked poultry products.
    D．H5N1 has caused more than 60 deaths worldwide.

    Los Angeles June 14, 2006 – Hollywood actress Daryl Hannah was arrested yesterday after spending two weeks sitting in a walnut tree on an urban farm a few kilometers from downtown Los Angeles. She was one of 40 people, including celebrities from the music and movie world, who were protesting at the proposed destruction of the 14 – acre farm. Police officers cut away branches from the tree and used a fire engine to reach Ms Hannah and her co – protester, environmentalist John Quigley. The two of them raised their fists in defiance（反抗）as they were removed.
    Protesters, some of whom had chained themselves to concrete –filled barrels（桶），said that it was essential to keep the farm operating, as it provided food for hundreds of poor families in the area. About 350 people grow produce and flowers on the farm, which has been there for more than a decade and is situated in an inner –city area surrounded by warehouses and railroad tracks. However, the local authority recently approved plans for the area to be cleared and redeveloped for the construction of a huge new warehouse.
    Ms Hannah, 45, star of films such as Splash and Kill Bill was not thrilled about being arrested. “But I felt it was important to show my support for the people,” she said. “This farm should be a model for sustainable (可持续的) urban agriculture. It needs to be replicated, not eradicated.”
    The record length for a tree protest is held by a woman called Julia Hill, who remained on top of a 30-metre-high redwood tree in Northern California for 738 days from December 1997 to December 1999. She was successful in saving the tree and those around it from destruction. Ms Hill was also at the Los Angeles urban farm project this week, but her presence failed to stop the inevitable (不可避免的). No sooner had the protesters been removed than earth-moving machines moved in and began to clear the land.

    To swim across the English Channel takes at least nine hours. It‘s hard work and it makes you short of breath. To fly over the channel takes only twenty minutes as long as you’re not held up at the airport， but it‘s an expensive way to travel. You can travel by hovercraft （气垫船）if you don’t mind the noise and that takes forty minutes. Otherwise， you can go by boat， if you remember your sea-sickness pills. All these means of transport have their problems， and the weary（厌烦的）traveler often dreams of being able to drive to France in his own car. “Not possible， you say. Well， wait a minute. People are once again considering the idea of a channel tunnel or bridge.” This time， the great London Council（议会）is looking into the possibility of building a channel link straight to London. A bridge would cost far more than a tunnel， but you would be able to make a journey by rail or by car on a bridge， yet a tunnel would provide a rail link only. Why is this idea being discussed again？ Is Britain realizing the need for links with Europe as a result of joining EEC？Well， perhaps， the main reason， though， is that a tunnel or bridge would reach the twenty square kilometers of London‘s discussed dockland（船坞）。 A link from London to the continent would stimulate（刺激） trade and revitalize（使重新具有活力）the port， and would make London a main trading center in Europe. With a link over the Channel， you could buy your fish and chips in England and be able to eat them in France while they are still warm！
    小题1:From the lines we can see that people crossed the Channel by ______ in the past.
    A．airB．boatC．swimmingD．A， B， or C
    小题2:The weary traveler thinks the best way to cross the Channel is ______.
    A．by swimmingB．in his own carC．by airD．by hovercraft
    小题3:A tunnel would cost______ a bridge.
    A．far less thanB．as much asC．far more thanD．as little as

    KANDAHAR, Afghanistan–-- Afghans burned tires and chanted “Death to America” after U.S troops fired Monday(April 12, 2010) on a civilian bus near Kandahar, killing four people and wounding more than a dozen. Afghanistan’s president accused NATO of breaking its commitment to safeguard civilian lives.
    The attack angered Afghan officials and the public in Kandahar, the Taliban’s birthplace, and dealt a blow to U.S and NATO efforts to win popular support for a coming offensive to drive the insurgents(叛乱分子) from the biggest city in the south. NATO expressed regret for the loss of civilian lives and said it was investigating.
    Nearly 200 Afghans blocked highway where the shooting occurred, burning tires, firing weapons and chanting “Death to America” and other slogans. They also called for the ouster (forcing somebody out of a pasition) of Afghan President Hamid Karzai, a Kandahar native who has been appealing for the people here to support the U.S-led campaign against the Taliban.
    “The Americans are constantly killing our civilians and the government is not demanding an explanation,” protester Mohammad Razaq said. “We demand justice from the Karzai government and the punishment of those soldiers responsible.”
    Kandahar, a city of about a half million people, is nominally under government control, but the Taliban have stepped up infiltration(浸润), staging attacks and threatening local people.
    “These foreigners have their enemies, but killing Afghans is not the answer,” said Abdul Hadi, who sells homemade herbal medicine in a public market. He said international forces should publish a schedule of their patrols(巡逻) so Afghans can keep out of the way.
    “Better yet, I would like to see them leave Afghanistan,” he added.
    Haji Zahir, who runs a transport firm, said it was time for U.S. and other foreign forces to withdraw from the country.
    “They say they want to bring security. It is all lies, lies. They kill Afghans. That is not the way to bring security,” Zahir said.
    46．According to the passage, we can safely conclude that____________.
    A．American soldiers are killing Talibans effectively
    B．Anger rises as US troops kill 4 Afghans on a bus
    C．NATO expressed great dissatisfaction with American troops
    D．Afghan President Hamid Karzai required NATO to withdraw
    47．The underlined word in Paragraph 5 nominally most probably means____________.
    A．completely unknown to the people in the world
    B．partially well-known to the people across the globe
    C．bearing the name of a famous person around the world
    D．officially described as something, when this is not really true
    48．As for NATO soldiers’ rude action, Abdul Hadi is ____________.
    A．absolutely angry and upset        B．a little pleased but impatient
    C．very angry and dissatisfied        D．impatient but bearable
    49．We can infer from the passage that____________
    A．NATO troops can completely control Afghanistan
    B．NATO troops can bring security to Afghanistan
    C．Afghans will accept NATO’s control sooner or later
    D．it’s impossible for NATO to conquer Afghanistan and its people
    50．Which statement is true according to the passage?
    A．NATO fails to win popular support for a coming offensive.
    B．Kandahar is the most important city in Afghanistan.
    C．NATO has really brought security to Afghanistan.

    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

    B
    London: It's well known that Charles Darwin's famous theory of evolution (进化) annoyed many people because it was against the Biblical view of creation. But few know that it also created problems for Darwin at home with his deeply religious wife, Emma.
    "Darwin held back the publication of On the Origin of Species to avoid offending (触怒) his wife," says Ruth Padel, the naturalist's great－great－granddaughter. "Emma told him that he seemed to be putting God further and further off", Padel says in her north London home. "But they talked it through, and Emma once said, ‘Don’t change any of your ideas for fear of hurting, me.’ ”
    As the world celebrates the 200th birthday of the man who changed scientific thought forever and the 150th anniversary of his book today, even his opponents admitted he was a giant figure.
    Though opposition to his theory, continues, it is the elegant explanation of how species evolutes through natural selection that makes his 200th birthday such a major event.
    More than 300 celebrations have been planned in Britain alone, where Darwin's face graces (使增光) the 10－pound bill along with that of Queen Elizabeth II.
    Shrewsbury, the central England town where Darwin was born and raised, is holding a month-long festival for its most famous son. Down House, his former home near London, will hold a permanent exhibition recreating some of his most famous experiments.
    Many more events have been planned all over the world.
    What would he be doing if he were alive today? Padel thinks he would properly be studying DNA and the immune system.
    45．The main purpose of the author is______.
    A．to say something about Darwin and his wife
    B．to introduce Charles Darwin and his theory of evolution
    C．to sing high praise for the book On the Origin of Species
    D．to report some celebrations of Darwin's 200th birthday and the 150th anniversary of his books
    46．Which of the statements is NOT true based on the passage?
    A．Everyone agrees with Darwin now.
    B．Darwin was brought up in Shrewsbury.
    C．Emma was not really fond of his theory.
    D．Darwin was very interested in living things.
    47．The underlined phrase "held back" in the second paragraph probably means______.
    A．prevented from                                                         B．kept a secret
    C．cared about                                                                 D．put off
    48．It can be inferred that the passage is most probably______.
    A．a scientific report                                                     B．a news report
    C．an English composition                                           D．a text
