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 preexisting conditions such as diabetes(糖尿病) or heart trouble. The victim should be checked for a medical bracelet(手镯)or 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 externally? Check skin color and temperature for additional indications of circulation problems.41        First aid may bring about all the following results EXCEPTA  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 injury42        Before we administer first aid to a victim, it is very important for usA  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 may be wearing.D  to take him to a hospital at once43        In administering first aid to a victim, you should first of allA  remove him from the accident scene.B  turn him overC  call for professional medical helpD  examine him care fully44        You may assess a victim’s condition by all the following EXCEPTA  checking whether there is a pulse.B  looking, listening and feeling for breathing.C  replacing his medical bracelet or card.D  examining whether the airway is open and clear.45        The purpose of the passage is to tell the readerA  the importance of protecting the accident scene.B  some basic facts about first aidC  what professional medical help is D  who ca administer first aid.  5部分：　补全短文（第46~50题，每题2分，共10分）阅读下面的短文，文章中有5处空白，文章后面有6组文字，请根据文章的内容选择5组文字，将其分别放回文章原来位置，以恢复文章原貌。请将答案涂在答题卡相应的位置上。

Lowering the Risk of Heart Disease

Like millions of other Americans, I come from a family with a history of the heart disease. My father had his first three heart attacks when he was only thirty-one. _____________(46) I grew up with heart disease. It was there, but I didn’t take it seriously.When I was thirty-one, my blood cholesterol（胆固醇）level was measured for the first time. It was 311 mg/dl, the doctor told me- an extremely high level that put me at a very high high risk of heart disease, especially with my family history. He sent me to the National Institutes of Health（NIH）to be screened for participation in a clinical trial._____________(47)At NIH, physicians explained the degree of risk associated with my blood cholesterol level and the nature of the experiment. This test involves putting a tube through a leg artery（动脉） up to the heart._____________（48）Learning about the risks of the experiment as well as the risk associated with my raised blood cholesterol level scared the life out of me. Although I was excluded from participating in the study, the experience may well have saved my life.For the first time, I began to realize the seriousness of high blood cholesterol.___________(49) But equally important, I got a taste of what it is like to be a patient, to have tests done on me and to think of myself as sick. This was hard to take.This experience taught me two lifesaving lessons. First, although I felt fit and strong, I was actually at high risk for heart disease because of my high blood cholesterol level. And with my family history, it could not be ignored.________________(50) A Second, I could lower my blood cholesterol level simply by changing what I ate.B I was three years old at that time.C There is not enough oxygen in the blood.D It was a heart attack just waiting to happenE The trial was designed to test the effect of lowering blood cholesterol on the risk of heart disease.F The death rate for the test was only 1 in 100, I was assured. 第6部分：　完形填空（第51~65题，每题1分，共15分）阅读下面的短文，文中有15处空白，每处空白给出了4个选项同，请根据短文的内容从4个选项中选择1个最佳答案，涂在答题卡相应的位置上

A  Special  Clock

    Every living thing has what scientists call a biological clock that controls behavior. The biological clock________(51) plants when to form flowers and when the flowers should open. It tells insects when to __________(52) the protective cocoon (防护卵袋) and fly away, and it tells animals and human beings when to eat, sleep and wake.Events outside the plant and animal__________(53) the actions of some biological clocks . Scientists recently found, for example, that a tiny animal changes the color of its fur because of the __________(54) of hours of daylight. In the short_________(55) of winter, its fur becomes white. The fur becomes gray brown in _________(56) in the longer hours of daylight in summer.Inner signals control other _________(57) clocks. German scientists found that some kind of internal clock seems to order birds to begin their long migration_________(58) twice each year. Birds _________(59) from flying become restless when it is time for the trip, _________(60) they become calm again when the time of the flight has ended.Scientists say they are beginning to learn which _________(61) of the brain contain biological clocks. An American researcher, Martin Moorhead, said a small group of cells near the front of the brain__________(62) to control the timing of some of our actions. These __________(63) tell a person when to wake, when to _________(64) and when to seek food. Scientists say there probably are other biological clock cells that __________(65) other body activities.51        A  says         B  asks        C  talks         D  tells52        A  reach        B  leave       C  escape        D  enter53        A  affect        B  adopt       C  avoid        D  express54        A  time         B  value       C  amount      D  number55        A  days         B  months     C  minutes      D  weeks56        A  shape        B  type        C  form        D  color57        A  physical      B  biological   C  mental       D  portable58        A  operation     B  flight       C  movement    D  transportation59        A  derived       B  prevented   C  originated    D  protected60        A  but          B  unless      C  therefore     D  if61        A  parts         B  ideas       C  sorts        D  images62        A  tries         B  likes        C  seems       D  wants 63        A  functions     B  places       C  actions      D  cells64        A  lie          B  sleep         C  stand       D  walk65        A  build        B  demand       C  reflect      D  control 答案：1A   2C   3B   4B   5A   6C   7D   8B   9B   10C   11B  12D  13D  14D  15C
