    Scientists have found what look like caves on Mars, and say they could be protecting life from the planet’s terrible environment.
    The first caves appear as seven mysterious black dots （点） on the pictures which were sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
    “If there is life on Mars, there is a good chance that you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features (特征) while working on a US Geological Survey Mars Cave Detection Program.
    Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
    One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air may be flowing out.
    “I said: ‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
    He agreed such caves could be perfect places to search for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.
    “Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria (细菌). A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
    The caves probably formed when tube-shaped lava flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining to flow out, forming caves.
    小题1: What does the passage mainly talk about?
    A．How the caves were formed on Mars.
    B．How NASA sent the pictures back to earth
    C．Caves on Mars may be full of hot air or a sign（迹象）of life.
    D．Scientists have completely recognized the surface of Mars.
    小题2: We can learn from the passage that __________.
    A．water has already been found on Mars
    B．the scientists found all the caves at night
    C．it is certain that there is life in these caves
    D．the surface of Mars is bitterly cold, radiation-soaked and dry
    小题3: According to the passage, Dr. Clarke was so excited because ________.
    A．such caves could provide energy for life
    B．they had finally found the caves on Mars
    C．such caves would be perfect places to search for life
    D．There would be life on Mars.
    小题4: Necessary conditions for life on Mars mentioned in the passage may include_________.
    A．lava and energyB．water and radiation from space
    C．gases and lavaD．water and protection from radiation
    小题5: what does the underlined word “ the planet” in paragraph 1 refer to?
    A．the MarsB．the earthC．the cavesD．radiation

    A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth．
    Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）．
    But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works．
    The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it．This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence．
    First they measured fluid intelligence of volunteers using standard tests．Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard．During the course, they needed to ignore irrelevant items, monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time．
    The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively．To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training．
    The results, published Monday in The Proceedings of the National Academy of Sciences，were striking．Improvement in the trained groups was a lot greater．Moreover，the longer they trained, the higher their scores were．All performers，from the weakest to the strongest，showed significant improvement．
    “Our results show you can increase your intelligence with proper training．” said Dr Jaeggi, a co-author of the paper．“No one knows how long the gains will last after training stops,” he added, “and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains．”
    小题1:.The researchers thought the key to improving the intelligence was ______________．
    A．memorizing telephone numbersB．improving working memory
    C．training in concentrationD．recalling a card
    小题2:.The following aspects of the training help increase intelligence EXCEPT___________．
    A．ignoring irrelevant itemsB．monitoring ongoing performance
    C．managing two tasks at the same timeD．using previous experience
    小题3:.When the experiment was conducted, the researchers______________．
    A．trained the four groups for the same period of time
    B．only made comparisons between the four groups
    C．compared the four groups with control groups
    D．trained the four groups together
    小题4:.By writing the article，the writer intends to ______________．
    A．inform the readers of a new study
    B．call on people to be trained to increase intelligence
    C．prove one’s born brainpower can be improved
    D．tell people the improved intelligence will last forever

    Who’s in control of your life? Who’s pulling your strings? For the majority of us，it’s other people—society，colleagues，friends，family or our religious community．We learned this way of operating when we were very young，of course．We were brainwashed．We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us．As Oscar Wilde puts it，“Most people are other people．Their thoughts are someone else’s opinions，their lives a mimicry，their passions a quotation．”
    So when people tell us how wonderful we are，it makes us feel good．We long for this good feeling like a drug—we are addicted to it and seek it out wherever we can．Therefore，we are so eager for the approval(赞同)of others that we live unhappy and limited lives，failing to do the things we really want to．Just as drug addicts and alcoholics live worsened lives to keep getting their fix(一剂毒品)，we worsen our own existence to get our own constant fix of approval．
    But，just as with any drug，there is a price to pay．The price of the approval drug is freedom—the freedom to be ourselves. The truth is that we cannot control what other people think．People have their own agenda，and they come with their own baggage and，in the end，they’re more
    interested in themselves than in you．Furthermore，if we try to live by the opinions of others，we will build our life on sinking sand．Everyone has a different way of thinking，and people change
    their opinions all the time．The person who tries to please everyone will only end up getting exhausted and probably pleasing no one in the process．
    So how can we take back control? I think there’s only one way—make a conscious decision to stop caring what other people think．We should guide ourselves by means of a set of values—not values imposed from the outside by others，but innate values which come from within．If we are driven by these values and not by the changing opinions and value systems of others，we will live a more authentic，effective，purposeful and happy life．
    小题1:．What Oscar Wilde says implies that        ．
    A．we have thoughts similar to those of others
    B．most people have a variety of thoughts
    C．other people’s thoughts are more important
    D．most people’s thoughts are controlled by others
    小题2:．What does the author try to argue in the third paragraph?
    A．Changing opinions may cost us our freedom．
    B．We may lose ourselves to please others．
    C．We need to pay for what we want to get．
    D．The price of taking the drug is freedom．
    小题3:．It can be concluded from the passage that         ．
    A． it’s better to do what we like
    B．we shouldn’t care what others think
    C．we shouldn’t change our own opinions
    D．it’s important to accept others’ opinions
    小题4:．The author tries to persuade the readers to accept his arguments mainly by      
    A．analyzing causes and effectsB．providing examples and facts
    C．discussing questionsD．making suggestions

    Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds;  (2)citrus （柑橘）fruits and tomatoes; (3) potatoes and other fruits and vegetables ; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal (谷物), rice is also in this kind of foods; (7) Butter or something like butter. 
    People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways.  People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
    There are two problems, then, in feeding the large number of people on earth. The first thin g is to find some ways to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kind of food to make them grow to be strong and healthy.
    小题1: According to the scientists, which of the following groups of food is the healthiest for your lunch?
    A．chicken, apples, cereal, cabbages. B．potatoes, carrots, rice, bread.

    You know that pearls grow inside oysters(牡蛎), but would you ever think to look for diamonds inside an ostrich(鸵鸟)? Well, a hunter once shot an ostrich and discovered, to his great surprise, that the big bird had swallowed a bunch of diamonds. How could such a strange thing happen?
    Like many other birds, the ostrich swallows small stones that stay inside its “gizzard”. The gizzard is a bird’s second stomach. It is where the food is ground up. The small stones help to grind up the food so it can be digested. The small stones do the chewing because birds don’t have teeth. In that case of the ostrich with the diamonds, the bird simply had expensive taste in rocks. It used the diamonds to digest its dinner.
    Diamonds and stones aren’t all that an ostrich will swallow. If there are no stones around, it will eat just about anything. Sadly for ostriches in zoos, this can be a fatal habit. The tendency to swallow anything it sees has caused the death of many an ostrich. Cruel or careless people often throw things into the bird’s living space. They throw keys, coins, and even large objects such as horseshoes. The ostrich swallows them without hesitation. Coins can be the worst. Inside the ostrich they wear down to a razor-sharp edge. They will cut open the bird’s gizzard from the inside. When one young zoo ostrich died, 484 coins weighing more than eight pounds were found in its gizzard.
    小题1:
    Which of the following best expresses the main idea of the passage?
    A．Birds often eat strange and funny things.
    B．Ostriches will swallow anything to help them digest food.
    C．One ostrich died with 484 coins in its gizzard.
    D．Ostriches are often hurt by cruel or careless people.
    小题2:
    The ostrich is not smart enough to ______.
    A．digest its own foodB．eat only diamonds
    C．avoid eating harmful objectsD．escape from the zoo
    小题3:
    The sentence “the small stones do the chewing” makes rocks seem as though they were ______.
    A．importantB．alive
    C．dangerousD．uncomfortable
    小题4:
    he word “fatal” in the third paragraph is another word for “______”.
    A．foolishB．carelessC．deadlyD．cruel

    A  rainfores（雨林）is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in（吸收） heat from the sun and adjust （调节）the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters（灾害） all over the world.
    In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit（受益）.
    There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run （长远看）it actually reduces the world’ s wood supply.
    Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in （在于）the world’s shrinking rainforests.
    小题1:.．Rainforests can help to adjust the climate because they________.
    A．reflect（反射） more heat into the atmosphere
    B．bring about high rainfall throughout the world
    C．rarely cause the temperature to drop lower than 16℃
    D．reduce the effect of heat from the sun on the earth
    小题2:.．What does the word “this” underlined in the third paragraph refer to?
    A．We will lose much more than we can gain.
    B．Humans have begun destroying rainforests.
    C．People have a strong desire for resources.
    D．Much carbon dioxide comes from burning rainforests.
    小题3:.What might be the best title for the text?
    A．How to Save RainforestsB．How to Protect Nature
    C．Rainforests and the EnvironmentD．Rainforests and Medical Development

    Bats are the only mammals(哺乳动物) which can fly properly. Other flying mammals have wings of thin skin which cover their sides between their front and back legs. They can only fly from tree to tree, but they cannot change direction when they want to.
    All bats fly at night and most of them hunt for flying insects(昆虫), such as bees. The common bat finds its food by making a constant noise that the human ear cannot hear. The bat listens for echoes(回声) of the noise as it bounces(反射) off the insects showing the bat their position.
    The Fruit bat feeds on many different kinds of fruit. It does not use echoes but instead has very large, special eyes to see even in low light. The largest Fruit bat has a wing length of 0.75 meters. The Vampire bat drinks the blood of large mammals, and a few bats catch fish, birds and even other bats.
    小题1: Some flying mammals are not real flyers because _____.
    A．they do not have wingsB．their wings are too thin
    C．they have skin between their legsD．they cannot turn around in the air
    小题2: When common bats hunt for food they _____.
    A．use echoes to kill the insectsB．make a noise to draw insects to them
    C．produce a sound and listen to the echoesD．listen noise made by the insects
    小题3: Unlike other bats, the Fruit bat _____.
    A．can see very wellB．eats fruit and fish
    C．has very long wingsD．has excellent hearings
    小题4:The word "it" in the second paragraph refers to _____.
    A．the batB．the echoC．the noiseD．the insect

    US bees operation keeping groups have been attacked seriously by so called Colony Collapse Disorder (蜂群衰竭失调)．Almost 1/2 of their worker bees have vanished during the past season．This disorder has also been reported in Israel, Europe and South America．Bees fly away from the hive and never return．Sometimes they are found dead; other times they are never found．Many crops and trees depend on pollination--- by bees to help them grow． 
    A new report says a virus may be at least partly responsible for the disorder in honey bee colonies in the United States．This virus is called Israeli acute paralysis virus．It was first found in Israel in 2004．Lan Lipkin at Columbia University in New York and a team reported the new findings in Science Magazine．Doctor Lipkin says the virus may not be the only cause．He says it may work with other causes to produce the collapse disorder．
    The team found the virus in colonies with the help of a map of honey bee genes that was published last year．They examined thirty colonies affected by the disorder．They found evidence of the virus in twenty-five of them, and in one healthy colony．The next step is further testing of healthy hives．
    The researchers suggested that the United States may have imported the disorder in bees from Australia．They say the bees may carry the virus but not be affected．
    The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroasis mite．This insect attacks honey bees, which could make the disorder more likely to affect a hive．Australian bee producers object to these suspicions．
    And some researchers suspect that bee production in the United States is down mainly because of the weather．Honey bees gather nectar from flowers and trees．The sweet liquid gives them food and material to make honey．But cold weather this spring in the Midwest reduced the flow of nectar in many flowers．Many bees may have starved．Dry weather in areas of the country could also be playing apart．
    Wayne Esaias is a NASA space agency scientist who keeps bees in his free time．He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country.
    小题1:What is the author’s attitude toward the cause of this disorder?
    A．DoubtfulB．NeutralC．SupportiveD．Negative
    小题2:The passage is mainly developed by            .
    A．presenting the effect and analyzing its causes
    B．making comparisons between two countries
    C．providing data and examples
    D．following the time order
    小题3:How many possibilities may be involved in the bee disorder according to the passage?
    A．ThreeB．FourC．FiveD．Six
    小题4:From the passage we can infer that           .
    A．American bees are more likely to defend themselves against hurt from other insects than Australian ones
    B．A collection of plants production in the U.S may be influenced by the bee disorder
    C．Israeli acute paralysis virus should be responsible for the disorder
    D．The solution to the disorder will be found eventually

    First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim’s condition from turning worse and provide relief from pain. First aid must be done as quickly as possible. In the case of the seriously injured, a few minutes can make the difference between complete recovery and loss of life.
    First-aid measures depend upon a victim’s needs and the provider’s level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal(脊柱)injury and paralysis(瘫痪).
    Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious, should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking other people or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes(糖尿病)or heart trouble. The victim should be checked for a medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim.
    First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim’s condition is known by the acronym(首字母缩写词)ABC, which stands for:
    A---Airway: is it open and clear?
    B---Breathing: is the person breathing? Look, listen, and feel for breathing.
    C---Circulation: is there a pulse? Is the person bleeding extremely? Check skin color and temperature for additional indications of circulation problems.
    小题1: First aid may bring about all the following results EXCEPT____.
    A．saving a victim’s life
    B．preventing a victim’s condition from getting worse.
    C．relieving a victim from pain
    D．helping a person avoid sudden illness or injury
    小题2: Before we administer first aid to a victim, it is very important for us ____.
    A．to make sure what to do and what not to do
    B．to refer to all kinds of handbooks on first aid
    C．to remove the ring or bracelet he/she may be wearing
    D．to take him/her to a hospital at once
    小题3:In administering first aid to a victim, you should first of all ____.
    A．remove him from the accident sceneB．turn him over
    C．call for professional medical helpD．examine him carefully
    小题4:The purpose of the passage is to tell the reader _____.
    A．the importance of protecting the accident scene
    B．some basic facts about first aid
    C．what professional medical help is
    D．who can offer first aid
