    The blue tits(山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding.
    Among many birds that nest in holes, the male has a light-coloured patch on its plumage(鸟羽) which acts as signal for drawing the female’s attention to a suitable nesting-place. Unlike the blue tit, the redstart(红尾鸲) may be only the male that strikingly coloured and the female is not beautiful.
    A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously(先前) checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal(显露) his tail.
    If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them.
    小题1:How do the blue tits choose their nest?
    A．They choose their nest together.
    B．The male chooses their nest.
    C．The house-hunter chooses their nest.
    D．The female chooses their nest.
    小题2:The writer was lucky to see ________.
    A．how the male made his tricks
    B．how an interested female played with the male happily
    C．what the male displayed and won the female
    D．that the male tried his best but failed to attract the female
    小题3:You can spot a pair of redstarts in a Walsh wood ________.
    A．at any timeB．regularlyC．in AprilD．occasionally
    小题4:The writer is probably ________.
    A．a bird expert B．a bird-hunter
    C．a bird raiserD．a scientist

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

    Almost every child is scared of something, from monsters in the cupboard to dogs in the park. But the fact that such fears are common and normal doesn’t mean they can be taken lightly. Kids experience fears and phobias (恐惧症) much more strongly than adults. And the influence of the fear can be physical as well as psychological (心理的). It can build up so they almost seem scared of everything-a kind of childhood anxiety. Dr. Creswell says:"Your child may always seem to expect the worst to happen and lack confidence in his or her ability to deal with any challenge.” So don’t make the same old mistake of treating them as if they’re silly for being “a scared cat”（胆小鬼）. Handing the fears is essential.
    Children can be born nervous and., if you have such a baby, you’ll tend to prevent them from getting worried. So if they fear dogs, you’ll keep them away from dogs, but in fact that can just confirm to the child that dogs are scary. What is worse, keeping your child away from what they fear can turn that feeling into a phobia. Instead, you should encourage them to get in touch with the thing they fear, in a safe and supportive environment. Dr. Andy Field, a researcher of childhood fears, says: “You shouldn’t force, for example, a dog anxious child to go up to a dog. But you can approach it yourself, show them there is nothing to be afraid of, stroke (抚摸) it, and talk about the dog being friendly. Once your child dares to stroke a dog-one that’s good with children, of course-then you should encourage them to carry on until they feel calmer, and reward them for ‘being brave’.”
    小题1:Children’s fears are usually taken lightly because     .
    A．they will not develop into phobias
    B．their influence is psychological
    C．they exist widely in the world
    D．they will disappear gradually
    小题2:If we fail to help children to overcome fears, they will    .
    A．make the same old mistake
    B．overcome them by themselves
    C．experience the worst of things
    D．grow up lacking self-confidence
    小题3:According to Dr. Andy Field, if a child is afraid of a cat, parents should     .
    A．tell the child not to be afraid of it
    B．show the child how to approach it
    C．keep the child away from it
    D．ask the child to stroke it

    M When Paul was a boy growing up in Utah, he happened to live near a copper smelter(炼铜厂), and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him.
    Years later Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back.. The answer from that big industry was “No.”
    Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn’t get his idea accepted.
    Paul later got married and had some kids. But his dream would not die. And then one night he did what he could with what he had. As Samuel Johnson wrote, “It is common to overlook what is near by keeping the eye fixed on something remote. Attainable good is often ignored by minds busied in wide ranges.” Under the cover of darkness, he went secretly into the wasteland and started planting.
    And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against the plain common sense. Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.
    Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.
    小题1:When Paul was a boy, _____.
    he had decided never to leave his hometown
    the economy of Utah depended wholly on the copper smelter
    no laws were made to protect the environment against pollution
    he had determined to stop the copper smelter polluting the area
    小题2:Why did Paul go to college to study the science of plants?
    He wanted to find out the best way to save the area himself.
    He was interested in planting trees since he was young.
    He wanted to get more knowledgeable people to help him.
    He thought his knowledge would make his advice more persuasive.
    小题3:What does the underlined phrase “the plain common sense” probably refer to?
    That it was impossible for trees to grow on the wasteland.
    That his normal work and life would be greatly affected.
    That no one would like to join him in the efforts.
    That he had to keep everything he did secret.
    小题4:The message of the passage is that _____.
    action speaks louder than words
    perseverance(持之以恒) will work wonders
    God helps those who help themselves
    many hands make light work

    Having one of those days or weeks — when everything seems to annoy you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster — often within a day or two.
    Walk it off
    Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.
    Tune it out
    Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.
    Give yourself a pep talk
    Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper; the pessimistic (悲观的) messages you’ve been giving yourself and then give optimistic answers. ("I still don’t have a job. "vs" I have two interviews next week.")
    Reduce your stress
    Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing (想象), all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to against distress is to make a to-do list. One reason for being in a bad mood is feeling you have no options(选择权) By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.
    Avoid things that won’t improve your mood
    TV may not help much: You need to increase your energy level and stimulate your mind something — that the TV show "Neighbors" won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta, produce a calming effect in people who have a desire for them.  
    小题1:We learn from the text that it might help rid us of a bad mood ________.
    A．to do nothing about it
    B．to take a long walk on the beach
    C．to do some exercises with light music
    D．to talk it to neighbours
    小题2: Why is it suggested that you close your eyes and picture the beach?
    A．It is not complicated to do so.
    B．It is an area to be easily controlled.
    C．It helps beat a bad mood.
    D．It brings us a new technique.
    小题3:TV may not improve your mood because ________.
    A．it sometimes shows what happens around you
    B．it keeps you stay unmoved
    C．it reminds you of eating and drinking
    D．it produces a calming effect
    小题4:This text most probably appears in ________.
    A．a book on physical exercisesB．a doctor’s handbook
    C．a noticeD．a magazine

    While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
    Steve Minear, UK
    Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
    Donal Trollop, Canada
    There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
    Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
    Paul Davies. USA
    小题1: The main purpose of Steve Minear’s writing is     .
    A．to report his classmates’ discussion B．to invite an answer to his question

    B．There are many reasons for going to Mars.
    C．Scientists become famous by doing research on Mars.
    D．It is possible to build an Earth-like environment on Mars.
    小题3:Paul Davies points out that      .
    A．humans need only a one-way ticket to Mars.
    B．two-way trips to Mars will be made safe soon
    C．it is easy to reduce the danger and cost of flights to Mars
    D．it is cheap to build an everlasting human settlement on Mars

    A．Humans will have to bring all they need from the Earth.
    B．Humans will find Mars totally unsuitable for living.
    C．Humans can produce everything they need.
    D．Humans can live longer in the colony on Mars

    Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. reseachers reported on Thursday.
    Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s(早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
    “Our research shows that the hormones of pregnancy(怀孕) are protecting the brain, including estrogen(雌激素), which we know has many neuroprotective (保护神经的) effects,” Kinsley said.  
    “It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”
    Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
    “When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.
    “They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain.”
    小题1: How do scientists know “Motherhood may make women smarter”?
    A．Some researchers have told them.
    B．Many women say so.
    C．They know it by experimenting on rats.
    D．They know it through their own experience.
    小题2: What does the phrase “litters of pups” mean in the second paragraph?
    A．Baby rats.B．Animals.C．Old rats.D．Grown-up rats.
    小题3:What can protect the brain of a woman according to the passage?
    A．Estrogen.B．The hormones of pregnancy.
    C．More exercise.D．Taking care of children.
    小题4:“It’s rat data but humans are mammals just like these animals are mammals.” What does the sentence suggest?
    A．The experiments on the rats have nothing to do with humans.
    B．The experiments on the rats are very important for animals.
    C．The experiments on the rats are much the same on humans.
    D．The experiments on the rats are much the same on other animals.
    小题5:Which title is the best for this passage?
    A．Do You Want to Be Smarter?
    B．Motherhood Makes Women Smarter
    C．Mysterious Hormones
    D．An Important Study

    To get cash out in the 21st century, you won’t need a bank card, a PIN(个人识别编号) or even have to move a finger. You will simply have to look the cash machine straight in the eye, declares National Cash Registers, a multinational company that makes automated teller machines, or ATMs. NCR has shown its first example machine that is believed to be the future of banking. Instead of asking you for your PIN on a screen, the Super Teller-Stella for short, asks you orally through a loudspeaker to look straight ahead while an infrared camera turns to your head, then your eye, and finally takes an infrared photograph of your iris(虹膜). For identification(识别) purposes, an iris picture is better than a fingerprint, with around 256 noticeable characteristics compared with 40 for fingerprints. This means that the chances of someone else being recognized in your place is about 1 in 1020. Once you’ve been identified, Stella greets you by name and says: “Would you like cash or a statement?” An infrared port allows the machine to send a bank statement straight to your pocket computer.
    小题1:What does this passage mainly talk about?
    A．A new medical instrument
    B．A new type of talking machine.
    C．A new type of cash machine.

    Most people think of racing when they see greyhounds (灰狗) and believe they need lots of exercise. They can actually be quite lazy! Greyhounds are good at fast races but not long-distance running. They do need regular exercise but they like to run for a short burst and then get back on the bed or a comfortable seat. Another misunderstanding is that greyhounds must be aggressive(好斗的) because they are big in size. In fact greyhounds love people and are gentle with children.
    Greyhounds can live for 12 – 14 years but usually only race for two or three years, and after that they make great pets. They don’t need a lot of space, don’t make a lot of noise, and don’t eat a lot for their size.
    Normally, greyhounds can be as tall as 90 cm. There is, however, a small-sized greyhound, which stands only 33cm. Greyhounds come in a variety of colors. Grey and yellowish-brown are the most common. Others include black, white, blue, red and brown or a mix of these.
    Greyhounds have smooth body coats, low body fat and are very healthy. Because they’re slim (苗条的) they don’t have the leg problems like other dogs the same height. But they do feel the cold, especially since they would much rather be at home in bed than walking around outside.    
    小题1:The text is written mainly______.
    A．to tell people how to raise greyhounds
    B．to let people know more about greyhounds
    C．to explain why greyhounds are aggressive
    D．to describe greyhounds of different colors
    小题2:It can be inferred that greyhounds_______.
    A．love big doghouses
    B．like staying in bed all day

    D．need some exercise outdoors
    小题3:Why does the author say that greyhounds make great pets?
    A．They are big in size.
    B．They live a very long life.
    C．They can run races for some time.
    D．They are quiet and easy to look after.
    小题4:If you keep a pet greyhound, it is important________.
    A．to keep it slim
    B．to keep it warm
    C．to take special care of its legs
    D．to take it to animal doctors regularly

    Have you ever thought, “I wish I could take a year off and just travel around the world”? Well, three lucky American teenagers were able to do just that. The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.
    This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
    Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (赞助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
    The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
    As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions. They realized that each of them can make a difference.
    小题1:These teenagers went on the journey around the world _____.
    A．to experience the most serous environmental problems on the earth
    B．to bring the kindness of America to the other parts of the world
    C．to go on sightseeing around the world
    D．to call on more teenagers to join Earthwatch Institute
    小题2:What’s true about their journey?  
    A．They had to pay for their journey on their own expense.
    B．They often had to move from one hotel to another.
    C．They had to take great pains to collect environmental information.
    D．They received a warm welcome every time they arrived at a new place.
    小题3: It can be inferred that Earthwatch Institute could be _____.
    A．an international university that takes in students from all over the world
    B．a TV station that makes programmes on the beautiful scenery of the earth
    C．a travel agency that organizes adventure trips specially for school children
    D．an organization that brings science to life for people concerned about earth’s environment
    小题4: What did they these teenagers learn from the journey?
    A．It was high time that people protected the environment.
    B．Long journey was not suitable for school children.
    C．It should take the whole world to help the children.
    D．Environmental problems can be solved if school children take part.
