    If you put a buzzard(秃鹰) in a cage without a roof(顶棚), the bird will be a prisoner. Even though it can fly, it can’t fly through the open roof. The reason is that a buzzard always begins a flight from the ground with a run of 3 or 4 meters. Without space to run, he will not even try to fly, but will stay in his small jail(监牢) for the rest of his life.
    The ordinary bat that flies around at night cannot take off from the ground. If it is placed on the ground, all it can do is shuffle(穿梭) about helplessly. If it reaches a higher place, it will be able to throw itself into the air. Then it takes off quickly. But on flat ground, it will never fly.
    A bee dropped into a cup will be there until it dies, unless it is taken out. It never sees the means of escape at the top, but keeps trying to find some way out through the sides near the bottom. It will look for away where none exists, until it completely destroys itself.
    In many ways, there are lots of people like the buzzard, the bat and the bee. They are struggling with all their problems and frustrations(挫折)，not realizing that the answer is right there above them.
    小题1:A buzzard can’t fly through the open roof of a cage because       .
    A．it is too big and heavy to fly up
    B．it feels the space is too small to start the flight
    C．it gets used to living in the cage without a roof
    D．it would like to spend the rest of his life in the jail
    小题2:Paragraph 2 mainly tells us that        .
    A．the bat is a kind of smart bird
    B．the bat can take off quickly on flat ground
    C．the bat flies only at night
    D．the bat can only take off from a higher place
    小题3:Which is NOT true about the bee?
    A．The bee doesn’t try to find a way to escape.
    B．The bee will die if it isn’t taken out of the cup in time.
    C．The bee always wants to escape from the cup near the bottom.
    D．The bee doesn’t see the way out at the top.
    小题4:What’s the purpose of the story?
    A．Many people are like the buzzard, the bat and the bee.
    B．Animals will also give up when in trouble.
    C．We should try new ways to deal with difficulties.
    D．We should solve problems by ourselves.

    BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).
    However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show, because it's impossible to cry in zero gravity.
    Of course, astronauts can still produce tears. But crying is much more difficult in space, according to The Atlantic(大西洋月刊) in January. Without gravity, tears don't flow(流动) down out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go-they just stick(粘) to your eyes.
    In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes...They just kind of stay there."
    Besides making your vision(视线)unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is stinging(刺痛) like crazy," Feustel told his teammate during the walk.
    Since gravity doesn't work in space, astronauts need some extra help to get rid of（除去） the tears. Feustel chose to rub his eyes against his helmet to wipe(擦) the tears away. Another choice is to just wait-"When the tears get big enough they simply break free of the eyes and float around," astronaut Ron Parise told The Atlantic.
    There are lots of small things-things like crying-that we are so used to on Earth. We usually take them for granted until they become a problem in a totally different environment, like space.  There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up（呕吐）everything in their stomach, according to the UK National Space Center.
    Therefore, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."
    小题1:From Paragraphs 2 and 3 , we can know that_______.
    A．astronauts are unable to feel sad in space
    B．astronauts produce fewer tears in space
    C．tears produced in space flow down more slowly
    D．tears produced in space don't flow downward
    小题2:What effect do tears have on astronauts?
    A．They cause physical pain.
    B．They bring comfort to them.
    C．They make their vision clearer.
    D．They float around and cause trouble.
    小题3:The underlined phrase "take them for granted" in paragraph 7 means _______.
    A．find them important
    B．consider them useless
    C．need them during an emergency
    D．fail to notice their presence(存在)
    小题4:The second-to-last paragraph (paragraph 7) is mainly about_______.
    A．suggestions of how astronauts can stay comfortable in space
    B．other basic things that are difficult to do in space
    C．why burping is impossible in space
    D．things human can't do without gravity

    Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet.
    Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.
    小题1:Who thinks that students won’t have to go to school?
    A．Everyone.B．The writer.C．Some people.D．The teachers.
    小题2:What does “a new kind of school” mean in the passage?
    A．A school with many new computers.B．A school with many new students.
    C．A school with many new teachers.D．A school connected to the Internet.
    小题3:What the writer thinks is that____________.
    A．schools are still necessaryB．more schools should be built
    C．there should be fewer schoolsD．more computers are needed in schools
    小题4:Why do people think learning can take place at home, at school, and in the office?
    A．Because whole city is connected to the Internet.
    B．Because everyone can go on the Internet.
    C．Because getting online is very easy.
    D．Because Scientists could give talks through the Internet.
    小题5:What fact does the passage NOT provide?
    A．Technology will change our way of learning.
    B．If you are a student, you can set up websites to show new technology.
    C．The schools provide computer labs for those who have no personal computers.
    D．On the Internet, you can visit another city's libraries as easily as the people there.

    A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce(确保) bedtime. Instead, it may be that biologically(生物学上)these sleepyhead(贪睡者)students aren’t used to the early hour.
    　　“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Brown’s School of Medicine.
    　　Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).
    　　Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
    　　Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice---their bodies are going through a change of sleep patterns.
    　　All of this makes the transfer(迁移)from middle school to high school---which may start one hour earlier in the morning----all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
    小题1:Carskadon suggests that high schools should not start classes so early in the morning because _______.
    A．it is really tough for parents to enforce bedtime
    B．it is biologically difficult for students to rise early
    C．students work so late at night that they can’t get up early
    D．students are so lazy that they don’t like to go to school early
    小题2:The underlined phrase nod off most probably means _______.
    A．turn aroundB．agree with othersC．fall asleepD．refuse to work
    小题3:What might be a reason for the hard transfer from middle school to high school?
    A．Adolescents depend more on their parents.
    B．Adolescents have to choose their sleep patterns.
    C．Adolescents sleep better than they did at childhood.
    D．Adolescents need more sleep than they used to.
    小题4:What is the test mainly about?
    A．Adolescent health care.
    B．Problems in adolescent learning.
    C．Adolescent sleep difficulties.
    D．Changes in adolescent sleep needs and patterns.
