    9．It is difficult for doctors to help a person with a damaged brain．Without enough blood，the brain lives for only three to five minute．More often the doctors can't fix the damage．Sometimes they are afraid to try something to help because it is dangerous to work on the brain．The doctors might make the person worse if he operates on the brain．
    Dr．Robert White，a famous professor and doctor，thinks he knows a way to help．He thinks doctors should make the brain very cold．If it is very cold，the brain can live without blood for 30 minutes．This gives the doctor a longer time to do something for the brain．
    Dr．White tried his idea on 13 monkeys．First he taught them to do different jobs，then he operated on them．He made the monkeys'blood go through a machine．The machine cooled the blood．Then the machine sent  the blood back to the monkeys'brains．When the brain's temperature was 10 C，Dr．White stopped the blood to the brain．After 30 minutes he turned the blood back on．He warmed the blood again．After their operations the monkeys were like they had been before．They were healthy and busy．Each one could still do the jobs the doctor had taught them．

    28．The biggest difficulty in operating on the damaged brain is thatA．
    A．the time is too short for doctors
    B．the patients are often too nervous
    C．the damage is extremely hard to fix
    D．the blood-cooling machine might break down
    29．The brain operation was made possible mainly byC．
    A．taking the blood out of the brain
    B．trying the operation on monkeys first
    C．lowering the brain's temperature
    D．having the blood go through a machine
    30．What is the right order of the steps in the operation？B
    a．send the cooled blood back to the brain
    b．stop the blood to the brain
    c．have the blood cooled down
    d．operate on the brain
    A．a，b，c，d   B．c，a，b，d   C．c，b，d，a   D．b，c，d，a
    31．With Dr．White's new idea，the operation on the damaged brainA．
    A．can last as long as 30 minutes
    B．can keep the brain's blood warm
    C．can keep the patient's brain healthy
    D．can help monkeys do different jobs．

    解答 28-31 ACBA
    28．A．细节理解题．根据"It is difficult for doctors to help a person with a damaged brain．Without enough blood，the brain lives for only three to five minute．"可知脑部手术的难度在于它的时间必须很短．故选A．
    29．C．细节理解题．根据"If it is very cold，the brain can live without blood for 30 minutes．"可知大脑可以在温度很低的情况下存活三十分钟．所以脑部手术通常在温度较低的情况下进行．故选C．
    30．B推理判断题．由最后一段"He made the monkeys'blood go through a machine．The machine cooled the blood．Then the machine sent  the blood back to the monkeys'brains．When the brain's temperature was 10 C，Dr．White stopped the blood to the brain．After 30 minutes he turned the blood back on．He warmed the blood again．After their operations the monkeys were like they had been before．"可知首先要冷却血液，然后将冷却的血液输送回大脑，再防止血液流回大脑，最后实施脑部手术．故选B．
    31．A．细节理解题．根据"If it is very cold，the brain can live without blood for 30 minutes．This gives the doctor a longer time to do something for the brain．"可知把大脑冷却可以延长手术时间，使手术时间延长到三十分钟．故选A．

    3．Move Earth-It's Not Science FictionLONDON-Scientists have found an unusual way to prevent our planet from overheating：move it to a cooler spot．All you have to do is send a few comets（彗星）in the direction of Earth，and its orbit will be changed．Our world will then be sent spinning into a safer，colder part of the solar system．
    This idea for improving our climate comes from a group of US National Aeronautics and Space Administration （NASA） engineers and American astronomers．They say their plan could add another six billion years to the useful lifetime of our planet-effectively doubling its working life．
    The plan put forward by Dr．Laughlin，and his colleagues Don Kory can sky and Fred Adams，needs carefully directing a comet or asteroid （小行星）so that it passes close by our planet and sends some of its gravitational energy to Earth．
    "Earth's orbital speed w ould increase as a result and we would move to a higher orbit away from the Sun，"Laughlin said．
    Engineers would then direct their comet so that it passed close to Jupiter or Saturn．The comet would pick up energy from one of these giant planets．Later its orbit would bring it back to Earth，and the process would be repeated．
    In the short term，the plan provides an ideal way to global warming，although the team was actually concerned with a much greater danger．The Sun is certain to heat up in about a billion years and so"seriously compromise"our biosphere（生物圈）-by cooking us．
    That's why the group decided to try to save Earth．
    The plan has one or two worrying aspects，however．For a start，space engineers would have to be very careful about how they directed their asteroid or comet towards Earth．The smallest miscalculation（误算）in orbit could fire it straight at Earth-with deadly results．
    There is also the question of the Moon．As the current issue of Scientific American magazine points out，if Earth was pushed out of its current position，it is"most likely the Moon would be stripped away from Earth"．This would greatly change our planet's climate．

    67．What makes the scientists plan to move Earth？C
    A．A few comets are moving to the direction of Earth．
    B．Earth's working life is coming to an end soon．
    C．Earth will become too hot for mankind to keep alive．
    D．The moon is moving farther and farther away from Earth．
    68．If the plan is successful，Earth will have a working life ofAyears．
    A.12 billion　B.6 billion　C.18 billion　D.24 billion
    69．What serious problems might the plan cause according to the passage？A
    A．The comet might hit Earth and man might lose the Moon．
    B．Earth might be moved too far away and man might be frozen to death．
    C．The comet might hit Jupiter or Saturn and never return to Earth．
    D．Earth's working life might be greatly shortened．
    70．What does the underlined word"compromise"mean？D
    A．Surround．B．Benefit．C．Share．D．Endanger．

    14．Beginning college is exciting：new ideas to explore，new challenges to be met and many decisions to be made；your future begins here．
    However，you will find college life is different from your previous school environment．Many of us can be easily defeated by the details of running a well-balanced life．While some of us may have the know-how，I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you．
    The following you may find useful about life on campus：
    •Plan well．There are so many new things to do at a new college or university．Give yourself time to make new friends and became familiar with the campus，but don't forget why you are there．Give some time for social activities and manage your time wisely．
    •If you don't have a"system"for planning your time now （like a day timer，a potable data book），get one．Most of all，don't depend on your memory．
    •Don't miss the guidelines．The restrictions，rules and regulations of all kinds can usually be found in your student's handbook．Consider them well-balanced food for thought．What dates are important？What pieces of paper need to be handed in？What can/can't you do in your student residence （住处）？Who has the right for what？What do you need to complete to graduate？
    •Write the word"STUDY"on the walls of your bedroom and bathroom，and maybe it will help to write it on a piece of paper and stick it on the telephone，TV and the kitchen table．Consider this-you are paying thousands of dollars for your course．You pay every time you have to repeat or replace a course．
    •Build your identity．This is the time for you to decide what to do and what not to do．Take as much time as you need to explore new ideas．Do not be afraid of the beyond．This is learning to make good choices．

    29．What is the main purpose of the passage？D
    A．To explain why college life is exciting．
    B．To persuade you to go to college．
    C．To describe the importance of college life．
    D．To offer advice on college life．
    30．According to the passage，why is it exciting to begin college life？D
    A．Because you will learn a lot of knowledge．
    B．Because you will no longer be afraid of challenges．
    C．Because you will make important decisions．
    D．Because you get yourself prepared for your future career and life there．
    31．The underlined word"know-how"refers toC．
    A．an understanding of college regulations．
    B．a brand-new environment．
    C．practical knowledge concerning college life．
    D．college rules and regulations．
    32．Which of the following statements is true according to the passage？A
    A．college students should know what they have fought for on campus．
    B．college students should spend as much time as possible on social activities．
    C．college students needn't learn from those who went to college before them．
    D．college students don't need to pay if they repeat or replace a course．
