    Every year landslides {滑坡} cause 25 to 50 deaths and $1.5 billion in damage in the United States．They account for 15 percent of the deaths from natural disasters in Europe．And in Decem­ber, a single event killed more than 200 people in the Philippines．Sending workers to stabilize (加固) mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties．Shaking drills produce harmful dust and loosen heavy, dangerous debris (米屑)．"It's quite a risky job," says Giorgio Pezzuto of D'Appolonia, an engineering company in Italy.
    D'Appolonia, working with eight other companies, may have an answer:  a three-ton robot called Roboclimber．"The idea is to operate a machine far away that can drill without a hu­man being on board,'" says Pezzuto, manager for the project, which is supported by the European Commission．Engineers claim that the machine will be faster and cheaper than manual labor．The robot, a large radio-controlled four-legged me­chanical spider (蜘蛛), has cost at least $2 mil­lion so far．The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the slope' s stability．Testing should begin in May.

    Most rain forests lie close to the equator(赤道),where the climate is often mild and there are long hours of sunshine.The warmth of the land heats the air above,causing it to rise and tiny drops of water to fall as rain.The rainfall can reach at least 98 inches a year.This wet,warm world with plenty of sunlight is perfect for plants to grow,so the trees grow fast with green leaves all the year round.The trees themselves also have an effect on the climate.They gather water from the soil and pass it out into the air through their leaves.The wet air then forms clouds,which hang over the treetops like smoke.These clouds protect the forest from the daytime heat and night-time cold of nearby deserts,keeping temperatures fit for plant growth.
    Rain forests slightly farther away from the equator remain just as warm,but they have a dry season of three months or more when little rain falls.Tree leaves fall during this dry season and new leaves grow when the wet season or monsoon(雨季) begins.Thus these areas are known as the “monsoon forest”.
    Another type of rain forest grows on tropical mountains.It is often called the “cloud forest” because clouds often hang over the trees like fog.
    The rain forest is the ideal place for the growth of many different trees.Most of them depend on animals to eat their fruits and spread their seeds.When the fruits are eaten,the seeds inside them go undamaged through animals’ stomachs and are passed out in their droppings.The seeds lying on the forest floor then grow into new trees.
    小题1:The climate of the rain forests near the equator is _______.
    A．mild,wet and windyB．hot,rainy and foggy
    C．hot,wet and cloudyD．warm,wet and sunny
    小题2:We can learn from the passage that _______.
    A．tree leaves are green all the time in the monsoon forest
    B．there is a dry season in the cloud forest on tropical mountains
    C．clouds help the plants in the rain forest near the deserts to grow
    D．the formation of climate in the rain forest has little to do with the trees
    小题3:According to the passage,_______ play the most important role in the spreading of seeds.
    A．animalsB．droppingsC．fruitsD．winds
    小题4:This passage is most likely to be found in _______.
    A．a travel guideB．a story book
    C．a technical reportD．a geography book

    阅读下面短文，简要回答问题。
    Baloney is a kind of sausage that many Americans eat often. The word also has another meaning in English. It is used to describe something—usually something someone says—that is false or wrong or foolish.
    Baloney sausage comes from the name of the Italian city, Bologna. The city is famous for its sausage, a mixture of smoked, spiced meat from cows and pigs. But, boloney sausage does not taste the same as beef or pork alone.
    Some language experts think this different taste is responsible for the birth of the expression baloney. Baloney is an idea or statement that is nothing like the truth...in the same way that baloney sausage tastes nothing like the meat that is used to make it.
    Baloney is a word often used by politicians to describe the ideas of their opponents.
    The expression has been used for years. Fifty years ago, a former governor of New York State, Alfred Smith, criticized some claims by President Franklin Roosevelt about the successes of the Roosevelt administration. Smith said, “No matter how thin you slice it, it is still baloney.”
    A similar word has almost the same meaning as baloney. It even sounds almost the same. The word is blarney. It began in Ireland about 1600.
    The lord of Blarney castle, near Cork, agreed to surrender the castle to British troops. But he kept making excuses for postponing the surrender. And, he made them sound like very good excuses, “this is just more of the same blarney.”
    The Irish castle now is famous for its Blarney stone. Kissing the stone is thought to give a person special powers of speech. One who has kissed the Blarney stone, so the story goes, can speak words of praise so smoothly and sweetly that you believe them, even when you know they are false.
    73.小题1:Find in the passage a word closest in meaning to the underlined word “baloney”.
                                                                      
    74.小题2:According to Americans, what does baloney refer to? (回答词数不超过8个)
                                                                      
    75.小题3:What do you know about the lord of Blarney castle, near Cork?  (回答词数不超过6个)

    It will be hot—hot enough that most locals will have cleared town for cooler places. But because athletes competing at the 2004 Olympics have no choice but to stay in the hot weather, many plan to turn to science to stay cool.?
    Some will put their hands in ice water just before competing and nearly all will be wearing fabrics(织物) designed with hot weather in mind.?
    “Normally we warm up before exercise,”said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia.“But in this case we're taking the warm out of warm up. It's like pre-cooling.”
    Experts are predicting(预测) the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64).?
    Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, other competitors will be pushing their limits during high temperatures.?       Drinking lots of water will help athletes keep cool, but humidity(湿度) remains a problem. The body's ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates(蒸发),resulting in dehydration(脱水) without the cooling.?
    “Getting hot is a real problem because when our brains heats up, the brain waves are more like when you're really sleepy. Everything feels harder,” said Sleivert.
    小题1: The passage mainly tells us that _______.
    A．why it is very hot in Athens?
    B．the hot weather is a big problem for Olympic athletes?
    C．how important science is to every athlete?

    B．some events in the Olympics will have to be put forward?
    C．competitors can't reach their limits in the hot weather?
    D．competitors will have to try their best to compete under any condition?
    小题3:The following things will be likely to happen in the hot weather EXCEPT _______.
    A．dehydration?
    B．being sleepy?
    C．that the blood in the body can become less and less?
    D．that the body's ability to cool down is weakened

    No one can believe that the over 6 300-kilometer long Great Wall might disappear some day.Believe it or not,the Great Wall is being destroyed by people.Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect,but about 80 percent is in danger.The Great Wall can be called “great” mostly because of its amazing length.But we should realize that the length was made up of one brick at a time.If we do nothing to save the Great Wall,it will become a series of separate wasteland rather than a historic site.

    Body language is a very powerful tool of a communication, not only between people but in the animal world as well.
    In many instances, we produce idioms which are all understandable by borrowing examples from animal communication.
    For example, we know that a frightened cat will arch（拱型）. From this starting-point we might hear the expression. “He gets my back up!” meaning “He makes me angry.”
    In the same manner, we know that many animals, if challenged（挑战）by attackers, will not turn and run away because this will encourage the attackers to attack them more forcefully. Instead, they will move backwards slowly to get out of harm’s way, always facing their attacker. We call this action “backing off” and it can be used as well with humans as with animals.
    In the case of humans, however, the back-off may not be physical but oral, as in using a kinder tone of voice and gentle words instead of fighting against the attackers.
    8. 小题1:When a cat arches its back high in a rigid curve, it shows that it is       .
    A．angryB．pleasedC．frightenedD．defeated
    9. 小题2:In the article “back off” means       .
    A．to escape from the attackers
    B．to get away quickly
    C．to keep out the attackers
    D．to avoid the attackers in words
    10. 小题3:Which of the following is wrong according to the article?
    A．To learn knowledge, humans must learn from animals.
    B．Both humans and animals have the body language.
    C．Both humans and animals have ways of getting out of harm.
    D．“Face your attackers” means to encourage yourself.
    11. 小题4:What is mentioned（提到）in this article belongs to study of English       .
    A．grammarB．idiomsC．expressionD．communication

    Right is right. Right? Of course. But is left wrong? Well, the Romans used to think so. They thought left-handed people were mistakes of nature. Latin, the language of the Romans, had many words that expressed this view. Some words we use today still have this meaning. The Latin word “dexter” means “right”. The English word “dexterous” comes from this word. It means “handy” (clever with hands). So, right is handy. But the Latin word for left is “sinister”. The English word “sinister” comes from this word. Sinister means “evil” (very bad). Is it fair to call right-handed people handy and left-handed people evil? Well, fair or not, many languages have words that express such beliefs. In old English, the word for left means “weak”. That isn’t much of an improvement over “evil”.
    Not very long ago, children were often forced to write with their right hands. Doctors have since found that this can be very harmful. You should use the hand you were born to use.
    People who use their left hands are just starting to get better treatment. But why they get all these bad names in the first place? One reason may be that there are not as many left-handed people as there are right-handed people. There is one left-handed person for every five right-handed ones. People who are different are often thought to be wrong. But attitudes do seem to be changing. Fair-minded right-handed people are finally starting to give left-handed people a hand.
    小题1:What does the passage lead us to believe when one writes?
    A．He can only use his right hand.
    B．He can only use his left hand.
    C．He can use either his left hand or his right hand.
    D．He can use both his left hand and his right hand.
    小题2:The last sentence of this article means ________.
    A．Fair-minded right-handed people want to change the habit of the left-handed people
    B．Fair-minded right-handed people are starting to help the left-handed people
    C．Fair-minded right-handed people are starting to use left hand to write and so on
    D．Fair-minded right-handed people are starting to give up using their left hands
    小题3: After we read the article we can certainly know that _______.
    A．left-handed people have been treated poorly
    B．the number of the left-handed people is larger than that of right-handed people
    C．right-handed people are much cleverer than left-handed people
    D．left-handed people are less smart but hardworking
    小题4:Which of the following is NOT right, according to the article?
    A．At one time, left-handed people were forced to use their right hands.
    B．Left-handed people today are being treated better than those in the past.
    C．There are not as many left-handed people as there are right-handed people today.
    D．“Dexterous” comes from Latin, means “evil” and English “sinister” means “handy”.

    Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.
    A political scientist from Indiana University whose work exploring how people come together to preserve their collective resources may provide important clues in the fight against climate change has become the first woman to win the Nobel prize for economics.
    Elinor Ostrom, 76, shares 2009 Nobel prize with fellow American academic Oliver Williamson, 77. The Royal Swedish Academy of Sciences announced to the world the pair had been chosen to win the 40th prize in economic sciences.
    For Ostrom, the award came, as a "big surprise". To rise to the peak of her area of learning has been a big journey, as she has had to struggle against her own weaknesses and the barriers of the system. At school in Los Angeles, she suffered from stuttering. She also faced the barriers common to most women of her generation entering the sciences --- she was discouraged from taking a PhD when she applied for graduate school.
    Her field of study has been striking for how cross-disciplinary it is. Early on she gained a reputation for bringing economics, political science and sociology together.
    What interests her is how common property can be managed successfully through groups in society. The findings of her research have been striking, as the Nobel committee pointed out, because they have challenged the traditional assumption that common property is poorly managed unless it is either controlled by government or privatized. She has shown how different individuals can band together and form collectives that protect the resource at hand.
    “A lot of people are waiting for more international co-operation to solve global warming.” Ostrom said , “It is important that there is international agreement, but we can be taking steps at family level, community level, civic and national level … There are many steps that can be taken. That will not solve it on their own but continuously will make a big difference.”
    81. How did Ostrom feel when she got the prize?  (not more than 3 words)
    82. What does “cross-disciplinary” mean according to the passage?  (not more than 9 words)
    83. Why was Ostrom advised not to take a PhD when she applied for graduate school?  (not more than 9 words)
    84. Why was Ostrom awarded the Nobel prize for economics?  (not more than 16 words)
