    The Galapagos a far-away archipelago(群岛) and largely untouched by man, is now facing a problem. Its local people, who live on the island of Santa Cruz, want to develop the business and tourist potential（旅游资源）of the island. Recently, they are locked in a bitter struggle with the naturalists who work at the Charles Darwin Centre, also on Santa Cruz. The naturalists want to protect the island’s wildlife which is already suffering as a result of human activity.
    The animals’ great threat used to be sailors who, hundreds of years ago, robbed the islands for food. They wiped out about 250,000 Giant Tortoises. For example, on Pinta, one of the smallest islands, there are no Giant Tortoises left at all. The last survivor, an 80-year-old Giant Tortoise called Lonesome George, lives under the protection of naturalists at the Darwin Centre.
    Today, the island’s animals are no longer hunted for food. But other dangers have replaced the threat from sailors. Goats, for example, introduced over the years by man, have gone wild. With no natural enemies, their number has reached 10,000 on the largest of the Galapagos islands, Isabella. They are eating huge quantities of plants, and robbed the remaining Giant Tortoises of food. The problem is now so bad that the National Park Service has hired hunters to kill the goats in order to save the Giant Tortoise from dying out.
    小题1:Today, you can find the Giant Tortoises on the island of _______.
    A．Santa Cruz B．PintaC．IsabellaD．Galapagos
    小题2:Which of the following shows the right relationship between the Galapagos, Isabella, Pinta and Santa Cruz?
    A．The Galapagos>Pinta>Isabella>Santa Cruz
    B．Isabella>Santa Cruz>the Galapagos>Pinta
    C．The Galapagos>Isabella>Santa Cruz>Pinta
    D．Isabella>the Galapagos>Pinta>Santa Cruz
    小题3:We can learn from the article the greatest danger to the Giant Tortoises is from________.
    A．sailorsB．huntersC．goatsD．the local people
    小题4:From the first paragraph we can infer that _____.
    A．the naturalists try to help the local people with their interest.
    B．The local people pay more attention to the economic growth than the wildlife there,
    C．The animals and plants are of great importance to the local.
    D．The naturalists don’t care about the local people at all

    小题1:A
    小题2:C
    小题3:C
    小题4:B

    小题1:在第二段中，８０岁的海龟生活在达尔文中心，而从第一段看，达尔文中心在Santa岛上。

    Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
    This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
    “We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
    小题1:According to the new findings, taking steps to prevent northern forest fires may __________.
    A．result in a warming climate
    B．cause the forest fires to occur more frequently
    C．lead to a longer fire season
    D．protect the forests and the environment there
    小题2:The following are all the immediate effects after a forest fire EXCEPT __________.
    A．large amounts of greenhouse gases enter the atmosphere
    B．the levels of ozone which is a type of oxygen increase
    C．snow on the ground mirrors more sunlight back into space
    D．ashes from the fire fall on the ice surface and take in more radiation from the sun
    小题3:Earlier studies about northern forest fires __________.
    A．analyze all aspects of how northern fires influence climate
    B．indicate that forest fires will pollute the atmosphere
    C．suggest that people should take measures to protect environment
    D．suggest that the fires will speed up climate warming
    小题4:The underlined phrase “soak up” in the last paragraph most probably means __________.
    A．releasedB．absorbedC．createdD．distributed
    小题5:From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.
    A．warm the climate as the supposition goes
    B．allow more snow to reflect more sunlight into space and thus cool the climate
    C．destroy large areas of forests and pollute the far-off sea ice
    D．help to gain more energy rather than release more energy

    For some time past,it has been widely accepted that babies—and other creatures—learn to do things because certain acts lead to “rewards(报酬)”,and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early time, had to be directly connected to such basic physiological(生理的) “drives” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.?
    It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except success in sight.?
    Papousek began his studies by using milk in the normal way to “reward” the babies and to teach them to carry out some simple movements, such as turning the head to one side or the other.Then he noticed that a baby who had  had enough to drink would refuse the milk but would still go on making the learned response(回答) with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “turned on” some lights—and indeed that they were able to learn some more turns to bring about(产生) this result,for example,two left or two right,or even to make as many as three turns to one side.?
    Papousek's light experiment was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the light closely ?although? they would “smile and speak” when the light was on.Papousek concluded that it was not the sight of the lights which pleased them.It was the success they were achieving in solving the problem,in mastering the skill,and then there is a basic human nature to make sense of the world and bring it under control.?
    小题1:According to the writer,babies learn to do things which _______.?
    A．will satisfy their surpriseB．will meet their physical needs?
    C．are directly connected to pleasureD．will bring them a feeling of success
    小题2:Papousek noticed in his studies that a baby _______.
    A．would make learned responses when it saw the milk ?
    B．would continue the simple movements without being given milk ?
    C．would turn its head to right or left when it had enough to drink?
    D．would carry out learned movements when it had enough to drink ?
    小题3:In Papousek's experiment babies make learned movements of the head in order to _______.
    A．be praisedB．please their parents?
    C．be rewarded with milkD．have the lights turned on ?
    小题4:The babies would “smile and speak” at the lights because _______.?
    A．they succeeded in “turning on” the lights?
    B．the sight of lights was interesting?
    C．they need not turn back to watch the lights?
    D．the lights were directly connected to some basic “drives”

    On the afternoon of September27, 2008, Astronaut Zhai Zhigang became the first Chinese man to walk in space on Saturday, clambering（爬上,攀登） out of China's Shenzhou VII space craft in a technological feat（成就，功绩）that made the Chinese people excited.

    "I'm feeling quite well. I greet the Chinese people and the people of the world," Zhai said as he climbed out of the craft at around 16:40 Beijing time, a historic achievement telecast live on CCTV. Tens of millions of Chinese viewers gathered before TV screens to watch the moment.
    Chinese President Hu Jintao and other top leaders had appeared at the Beijing Aerospace Control Center to watch the live transmission of Zhai's spacewalk.
    Zhai, 42, chosen by an expert team for the first "out-of-capsule activity," showed a red national flag, helped by colleague Liu Boming, who also briefly popped his head out of the capsule.
    Zhai slowly made his way towards a test sample of solid lubricant（润滑剂）outside the capsule, took a sample and handed it to Liu.
    Zhai safely returned inside the craft after about 20 minutes. The walk marked the highpoint of China's third manned space journey, which has received widespread media coverage.
    Zhai wore a $4.4 million Chinese-made suit weighing 120-kg. Liu wore a Russian-made one and acted as an assistant.
    The third crew member, Jing Haipeng, monitored the ship from inside the re-entry module. w.w
    The risky maneuver is a step towards China's longer-term goal of building a space lab and then a larger space station, analysts said.
    "On this flight, Chinese people's footprints will be left in space for the first time," said a commentary（评论）by the Xinhua news agency.
    The astronauts went aboard on their walk after receiving a clean bill of health from doctors on the ground at mission control in Beijing, Xinhua said.
    Zhai's suit has 10 layers and takes up to 15 hours to assemble and put on.
    China's first manned spaceflight was in 2003. A second, two-manned flight followed in 2005. The only other countries that have sent people into space are Russia and the United States.
    Shenzhou VII took off on Thursday and is due to land on the northern steppes(草原) of Inner Mongolia on Sunday.
    小题1:The space walk done by the Chinese astronaut was historic because ______.
    A．it was telecast liveB．there were more Chinese viewers than ever
    C．it was the first space walk carried out by Chinese astronauts
    D．top leaders watched the space walk
    小题2: The following statements are true except ______.
    A．The lubricant put outside the capsule was a test sample
    B．It took Zhai Zhigang about 20 minutes to return to the craft safely
    C．Many televisions and newspapers around the world reported the event
    D．There is an aerospace control center in the capital
    小题3:The significance of the space walk is ______.
    A．that the astronaut can work outside the spacecraft
    B．it marks a successful step towards China’s longer-term goal of building a space lab as well as a space station
    C．it has attracted tens of millions of people to watch the walk
    D．that the Chinese-made space suit can be used in space

    This year some twenty-three hundred teenagers（young people aged from 13 —19）from all over the world will spend about ten months in U. S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
    Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.
    Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. The school was completely different from what he had expected — much harder. Students rose respectfully① when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
    Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual. Fred found the food too simple at first. Also, he missed having a car.
    “Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
    At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize② American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”
    Notes:
    ①    respectfully  adv. 尊敬地，谦恭地
    ②    criticize  vt. 批评，责备
    Choose the best answers according to the above:
    小题1:This year       __ teenagers will take part in the exchange programme between America and other countries.
    A．twenty-three hundredB．thirteen hundred
    C．over three thousandD．less than two thousand
    小题2:The whole exchange programme is mainly to        __.
    A．help teenagers in other countries know the real America
    B．send students in America to travel in Germany
    C．let students learn something about other countries
    D．have teenagers learn new languages
    小题3:What is particular in America schools is that        __.
    A．there is some middle ground between the two teaching buildings.
    B．there are a lot of outside activities
    C．students usually take fourteen subjects in all
    D．students go outside to enjoy themselves in a car
    小题4:After experiencing the American school life, Mike thought        __.
    A．a better education should include something good from both American and Germany
    B．German schools trained students to be better citizens
    C．American schools were not as good as German schools
    D．the easy life in the American school was more helpful to students

    Listening to music can help me focus better. Since I discovered it two years ago, I’ve used music to get through boring work or to focus creatively. I’ve found that it can make even the dullest jobs enjoyable and help clear mental blocks to creativity.
    I first noticed the good effects of music while playing video games. It was a few days before Christmas in 2005 and I was playing online video games. My parents had just given me a new MP3, so I decided to listen to music through the headphones while I played. After a few minutes I noticed a great change in my style of play. I was playing more naturally. The music relaxed me, and, to a certain extent, distracted me from the game, allowing my subconscious (潜意识的) talent to come through. The music also helped me block out the outside world. With those headphones on I was like a machine, moving from one task to the next without unnecessary thoughts or actions.
    Music can also have a great effect on mood. If I’m in a bad mood at work, I’ll listen to some of Bob Marley’s and get down to business. It always takes my mind off what I’m doing and makes me a happier person. The same is true for classic rock. One summer, I did a boring job collecting bottle openers by hand. Without a radio playing classic rock in the background, I would have hated life.
    Listening to music with relaxing rhythms and a positive message helps you forget your work and think happy thoughts. But the results you see will depend heavily on your personal tastes. Experiment with the types of music you listen to during certain tasks. By trial and error you’ll finally discover your best choice. I’m always looking for new concentration aids, so I’d love to know what type of music works best for me.
    小题1: We can infer that the passage was written in __________.
    A．2005B．2006C．2007D．2008
    小题2:The author first discovered the effects of music __________.
    A．from his parentsB．by chance

    A．It helps him block out the outside world.
    B．It arouses his subconscious talent.
    C．It helps his mind relax.
    D．It makes him work without any thought.
    小题4:The author mentions the experience of collecting bottle openers in Paragraph 3 to ________.
    A．tell us that life is dull
    B．prove that music affects mood
    C．tell us how to seek happiness
    D．tell us bad mood can affect work

    "Reduce, reuse and recycle, this familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways.
    The concept is being used to deal with one possibly dangerous form of waste – electronic junk (电子垃圾), such as old computers, cell-phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.
    “A lot of these materials are being sent to developing nations under the excuse of reuse – to bridge the digital divide,” said Richard Gutierrez, a policy researcher.
    One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.
    Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”
    China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial, is finally beginning to take the lead.
    小题1:The underlined word “unscrupulous” in Paragraph 1 probably means ________.
    A．unsafeB．trickyC．wrongD．immoral
    小题2:What does the fourth paragraph mainly discuss?
    A．Old computers and TVs still work before they are sent abroad.
    B．Poor people break up e-waste to collect some valuable materials.
    C．A lot of e-waste is dumped in developing countries.
    D．The problem of e-waste is growing in developing countries.
    小题3:From what Gutierrez said we can learn that ________.
    A．exporting countries should mainly be responsible for this problem.
    B．neither rich nor poor countries should be blamed for this problem
    C．developing countries should be responsible for this problem
    D．poor countries should blamed for this problem
    小题4:It can be inferred from the last paragraph that _______.
    A．China has hidden a large amount of e-waste in many secret places
    B．China has greatly changed hre idea about the problem of e-waste
    C．China has prevented poisonous materials from entering China for a long time
    D．China is falling behind other countries in dealing with e-wast
    小题5:The passage mainly tells us that _______.
    A．developing countries are facing serious environmental problems
    B．e-waste is a growing problem in developed countries
    C．e-waste is sent to developing countries under the excuse of reuse
    D．developing countries are making full use of e-waste
