    Trees are useful to man in three important ways: They provide him with wood and other products; they provide him shade;. and they help to prevent droughts（早灾）and floods.
    Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important．In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, 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 more serious: for where there are trees, their roots break up soil allowing the rain to sink in and also bind（固定）the soil, thus preventing 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 the top-soil is gone, nothing remains but worthless desert.
    Two thousand years ago，a rich and powerful country cut down its trees to build warships, with which to gain itself an empire(帝国）．It set up the empire, but, without its trees, its soil became poor and grew weak. When the empire fell to pieces, the home country found itself faced by floods and starvation（饥荒）．

    A．they give them wood and other productsB．they give them shade
    C．they help him prevent droughts and floodsD．they help him made money
    小题2:In many parts of the world, forests slowly disappear because___________．
    A．many trees have been cut down by manB．man has not paid enough attention to planting trees
    C．new trees are not looked after properlyD．all the above
    小题3:Land becomes desert after all trees are cut down because____________．
    A．roots of trees break up the soilB．there are too many rainfalls
    C．there are no larger trees to keep rain and protect the top-soilD．strong winds bring a lot of sand
    小题4:The country mentioned in the passage suffered from floods and starvation  because________.
    A．it set up an empireB．the empire fell to pieces
    C．it built too many warshipsD．it lost its trees

    Scientists are worried that an asteroid(小行星) will possibly hit the earth in 2036. If scientists are right, planet earth is 24 years away from a major disaster.
    Scientists have been monitoring the progress of a 390-metre-wide asteroid ever since it was discovered last June. They have announced that it could hit the earth, causing huge damage, in 2036.
    NASA estimates that the impact from the asteroid named after Apophis and ancient Egyptian demon(魔鬼) would release more than 100,000 times the energy released in the nuclear explosion over Hiroshima. Thousands of square kilometers would be directly affected by the explosion. The whole planet would see the effects of the dust released into the atmosphere.
    This is the worst possible scenario(情景) of any asteroid in recorded history.
    Having more than 20 years’ warning of possible impact might seem plenty of time. But scientists insist that there is actually very little time left to decide.
    Luckily, however, they aren’t short on ideas for deflecting the asteroid. The favored method is also probably the easiest—throwing a spacecraft at the asteroid to change its direction. The European Space Agency plans to test this in the next decade.
    One idea that seems to have no support from astronomers is the use of explosive, although this sounds more likely to the public or Hollywood producer.
    At present, scientists are trying to make a better estimate of how much time we have, through more observations.
    In spring of next year, there will be another chance for radar observation of Apophis. This will help astronomers calculate the orbits of the asteroid more accurately.
    If, at that stage, they can’t rule out an impact with the earth in 2036, the next chance to make better observations will not be until 2016, then 2029.
    “If we wait until 2029 and the worst—case scenario turns out to be true, it would seem unlikely that we’d be able to do anything about 2036,” warns Prof Fitzsimmons.
    小题1:What does the underlined word “deflecting” most probably mean?
    A．making it smaller.
    B．observing it clearly enough.
    C．dividing into pieces.
    D．changing its direction.
    小题2:According to the scientists’ observation, _______.
    A．the asteroid named Apophis will explode in 2036.
    B．the asteroid named Apophis might hit the earth in 2036.
    C．the asteroid named Apophis is 24 years old.
    D．there is plenty of time to decide the way we deal with the asteroid.
    小题3:What is the impact from Apophis if it hits the earth?
    A．It will damage Hiroshima.
    B．Thousands of square kilometers would see the effects of the dust released into the atmosphere.
    C．It might be the worst damage caused by asteroids in recorded history.
    D．The whole planet would be directly affected by the explosion.
    小题4:It can be inferred from the text that _____.
    A．Hollywood producers will explode Apophis to avoid its hit.
    B．There are only two chances for scientists to make better observations if they can’t grasp the chance next year.
    C．NASA plans to throw a spacecraft at Apophis to change its direction.
    D．It is supportive from astronauts that we explode the Apophis.

    To what degree can a computer achieve intelligence(智力)? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.
    If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.
    He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get stranger answers. A question about Smarter Child’s age returns, “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”
    Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www. intellicast. com.
    Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I., Artificial Intelligence, he must overcome two problems.
    The first is that computers find it difficult to read web pages because the files are labeled in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.
    Another problem is that while Smarter Child can process(处理) information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.
    小题1:From the text we can infer that www. Intellicast. com is a website               .
    A．which is specially designed to help Smarter Child
    B．where we people can find Smarter Child
    C．where weather forecasts are made
    D．which is about artificial intelligence
    小题2: It is probably most difficult for Smarter Child to               .
    A．tell us how to spell a difficult word
    B．tell us how the American government is run
    C．provide us with a famous poem by Shakespeare
    D．learn how to tell right behaviors from wrong ones.
    小题3: Which of the following is TRUE according to the text?
    A. Smart Child has his own memory bank big enough for all kinds of information.
    B. A. I. Artificial Intelligence is probably the name of a film about a boy-computer.
    C. Smart Child can recognize different files and find information needed on his own.
    D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.
    小题4:Which of the following is the best title for the passage?
    A．A New Web ChildB．Smarter Child
    C．The Future of Internet D．Intelligence Development

    We all know how important human life is—it’s priceless. It doesn’t matter where you are from or what the color of your skins is—all people are human beings. Firstly, we can tell you that the lives of your relatives could depend on your ability to give first aid. If you think highly of human’s life, this website is for you! Here you can find information about first aid.
    The very first thing that you should do when you see an accident is to evaluate the situation and prevent further dangerous incidents. First of all, you have to recognize what has happened and what the dangers to rescuers and victims are. Think about how to take care of the victims.
    Helping usually takes place in very difficult conditions and injuries can be very bad. Therefore, you cannot be too afraid of making mistakes to help. Sometimes you have to face the fact that regardless of your actions and your efforts the victim’s condition might not improve—he or she could even die. In some cases even professional medical aid may not succeed. If you have done everything you think you should do, you shouldn’t feel guilty.
    Do not expose yourself to danger. Giving first aid can be dangerous. While trying to help a victim, do not forget about your own safety. If something happens to you, you won’t be able to help anyone.
    Call for help after you find out the condition of a victim. But remember if a victim faints due to breathing failure caused by drowning, choking or poisoning, you should first take actions that help to bring back the heart beat and breathing. While calling, talk shortly but clearly. Always provide the following information: the location of the accident, the kind of accident, the number of the injured and your full name and phone number and so on.
    小题1:The passage is probably taken from _________.
    A．a newspaperB．the InternetC．a textbookD．a guide book
    小题2:The underlined word “ evaluate” in Paragraph 2 is closest in meaning to _______.
    A．leaveB．protectC．avoidD．judge
    小题3: What’s the main idea of Paragraph 3?
    A．You should learn some professional knowledge about first aid.
    B．You shouldn’t feel guilty if you don’t know about first aid.
    C．Try your best to give first aid and don’t be afraid of making mistakes
    D．Don’t make mistakes when you are giving first aid.
    小题4:The author thinks that helping a victim can be ____________.
    A．riskyB．shockingC．excitingD．boring
    小题5:It can be inferred from the passage that __________.
    A．young people must learn how to give first aid
    B．you should forget about your own safety while giving first aid.
    C．when you see an accident you should do nothing but call the police.
    D．when calling for help you should give all relevant details.

    Do American children still learn handwriting in school? In the age of the keyboard, some people seem to think handwriting lessons are on the way out. 90% of teachers say they are required to teach handwriting.But studies have yet to answer the question of how well they are teaching it. One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting. Some teachers are teaching handwriting by providing instruction for 10 ?15 minutes a day, and then other teachers who basically teach it for 60 to 70 minutes a day — which really for handwriting is pretty much.
    Many adults remember learning that way — by copying letters over and over again. Today’ s thinking is that short periods of practice are better. Many experts also think handwriting should not be taught by itself.Instead, they say it should be used as a way to get students to express ideas. After all, that is why we write.
    Handwriting involves two skills. One is legibility,_which means forming the letters so they can be read. The other is fluency — writing without having to think about it. Fluency continues to develop up until high school.
    But not everyone masters these skills. Teachers commonly report that about one?fourth of their kids have poor handwriting. Some people might think handwriting is not important any more because of computers and voice recognition programs.
    But Steve Graham at Vanderbilt says word processing is rarely done in elementary school, especially in the early years. American children traditionally first learn to print, and then to write in cursive, which connects the letters. But guess what we learned from a spokeswoman for the College Board, which administers the SAT college admission test. More than 75 percent of students choose to print their essay on the test rather than write in cursive.
    小题1:We can learn ________ from Paragraph 1.
    A．teaching handwriting is a basic requirement in teaching job
    B．most teachers prefer to teach handwriting
    C．teachers spend little time in teaching handwriting
    D．a keyboard has taken the place of the handwriting entirely
    小题2:Which of the following is WRONG for traditional handwriting in the USA?
    A．The students are taught by practicing a long period.
    B．The letters are repeated many times.
    C．Handwriting includes two skills.
    D．To write in cursive is taught first.
    小题3:The underlined word “legibility” in Paragraph 3 means ________.
    A．easy to readB．complexC．unexpectedD．unreadable
    小题4:The best title for the passage is ________.
    A．How to improve handwriting in school
    B．Right or wrong: the death of handwriting
    C．Handwriting involves two skills
    D．Handwriting lessons are on the way out
    小题5:The author’ s attitude towards whether still to learn handwriting in school is________.

    If your cellphone suddenly stops working, don’t blame the service provider．The malfunction（故障） might well have been caused by something bigger -- a solar storm．Experts expect that Earth will see more solar activity in the near future．The malfunction of electronic devices will just one of the effects．
    Sunspots（太阳黑子） serve as an indicator of the sun’s activity．For the past two years, sunspots have mostly been missing．Their absence, the most prolonged in nearly 100 years, has taken even seasoned sun watchers by surprise．
    When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This “solar minimum” doesn’t last long. Within a year, sunspots and solar storms begin to build toward a new crescendo, the next solar maximum.
    What’s special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the most active on record: more sunspots and more solar storms. However, sunspots are mostly missing now.
    Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina.
    What the sun will do next is beyond our ability to predict. Most astronomers think that the solar cycle will go on but at low level. However, there is also evidence that the sun is losing its ability to produce sunspots. By 2015, they could be gone altogether.
    小题1:The sun watcher feel surprised at            .
    A．the longest sunspots’ absenceB．the largest sunspot number
    C．the malfunction of electronic devicesD．the serious damage by sunspots
    小题2:What does the underlined word “crescendo” in paragraph 3 most probably mean?
    A．small number B．high level
    C．usual cycleD．fresh start
    小题3:We can infer that in the past two years         .
    A．solar activities have brought much trouble to our life
    B．the number of sunspots has increased to a large extent
    C．the solar minimum took the place of the solar maximum
    D．our cellphones have seldom been interrupted by the solar storm
    小题4:Which statement does the text lead you to believe?
    A．Solar activities do no harm to our daily life.
    B．Hurricane Katrina is also a type of solar storms.
    C．It’s difficult to predict sunspots.
    D．From now on there’ re no sunspots.
    小题5:What is the passage mainly about?
    A．The earth is in close contact with the sun.
    B．Sunspots can cause trouble to our life.
    C．Introduction of sunspots.
    D．Introduction of the solar storm．

    In many countries today, laws protect wildlife. In India, the need for such protection was realized centuries ago.
    About 300 B.C. an Indian writer described forest that were somewhat like national parks today. The killing of game beasts was carefully supervised(监视). Some animals were fully protected．Within the forest, nobody was allowed to cut timber(wood for building), burn wood for charcoal(炭), or catch animals for their furs. Animals that became dangerous to human visitors were caught or killed outside the park so that other animals would not become uneasy.
    The need for wildlife protection is greater now than ever before. About a thousand species of animals are in danger of extinction, and the rate of extinction was about one species every fifty years from A.D. 1 to 1800, but now it is about one species every year. Everywhere, men are trying to solve the problem of protecting wildlife caring for the rapid growth of the world’s population.
    小题1: In forest of ancient India __________.
