You might not know it, but there is something wonderful at your fingertips. You can make people happier, healthier and more hard-working just by touching their arms or holding their hands.
    Doctors say that body contact is a kind of medicine that can work wonders. When people are touched, the quantity of hemoglobin — a type of matter that produces the red color in blood increases greatly. This results in more oxygen reaching every part of the body and the whole body benefits. In experiments, bottle-fed baby monkeys were separated from their mothers for the first ten days of life. They became sad and negative. Studies showed the monkeys were more probable to become ill than other babies that were allowed to stay with their mothers.
    Human babies react in much the same way. Some years ago, a scientist noticed that some well-fed babies in a clean nursery became weak. Yet babies in another nursery were growing healthily, even though they ate less well and were not kept as clean. The reason, he concluded, was that they often had touches from nurses.
    Experiments show that most people like being touched. And nearly all doctors believe touch helps to reduce patients' fear of treatment. Of course there is time when a touch is not welcome. But even if we don’t like being touched, a smile can make us feel better. Smiling increases blood flow and starts the production of “happy brain” chemicals.
    So let’s have a big smile and don’t forget to keep in touch.
55. Which of the following is NOT true?
A. Everyone knows that body contact can make people happier.
B. People may work harder because of body contact.
C. Your fingertips can do something wonderful.
D. People may not understand the importance of touching.
56. According to the passage, ______.
A. human brains need oxygen and blood supply now and then
B. touches from doctors and nurses have nothing to do with treatment
C. new-born baby monkeys should stay away from their mothers
D. not all the people like being touched
57. The word “benefits” in the second paragraph probably means ______.
A. to be useful or helpful             B. to get something useful or helpful
C. to be strong                                D. to be hurt
58. The best title for the passage might be ______.
A. Why People Touch                B. Smile and Touch
C. Wonders of Touch                  D. Touch or Not

Few people would question the value of taking part in sports for young people. With proper training, supervision, protective equipment and techniques, and a proper emphasis on winning, sports can develop a healthy body and spirit and a life-long interest in being active and fit. Without such measures, childhood sports can lead to injuries and even paralysis or death.

Even in the best conditions, no activity can be risk-free. But most serious hazards are preventable. Cyclists and football players can reduce their risks by wearing helmets, hockey players by wearing masks; basketball and tennis players by wearing eye guards; baseball players by wearing batting helmets.

Besides, risks to individual players can often be found, and thus prevented, through a properly performed medical exam before a child plays. For accidents that may not be preventable, having an emergency plan and first-aid equipment, and someone trained to use the equipment, can be lifesaving.

Still, each year, according to the American College of Sports Medicine, more than 775, 000 children under 14 are treated in emergency rooms for sports injuries, nearly half of them preventable. An estimated 300,000 athletes experience exercise-related head illnesses each year, and almost all of them should have been avoided.

Further, from half to three-fourths of sports-related concussions(脑震荡) are never even diagnosed; the injured are often sent back to play too soon and put at risk of another more serious brain-damaging concussion. To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers’ Association, offers a three-hour online safety course for coaches for $28 at www. SportsSafety. Org.

52. Which of the following is true according to the passage?

A. All the accidents can be prevented.

B. All the accidents cannot be prevented.

C. Lives can be saved so long as there is proper equipment.

D. Lives cannot be saved even if there is proper equipment.

53. What does the underlined word “hazards” (in Paragraph 2)

A. Mistakes.                        B. Diseases.                         C. Dangers.                         D. Situations.

54. It is implied in the passage that _____________.

A. prevention of injuries is not paid enough attention to     B. children under 14 are more easily hurt in sports

C. most head illnesses are related with exercise                  D. none of the head illnesses should have happened

55. What can coaches mainly learn from the online safety course?

A. How to cure brain-damaging concussion.                      B. How to diagnose brain-damaging concussion.

C. How to predict the possibility of brain damage.             D. How to deal with the injured properly.

Years ago, a cigarette commercial asked if you were smoking more, but enjoying it less. That describes the way many of us live today. We are doing more, but enjoying it less. And when that doesn’t work, we compound the problem. In our frantic search for satisfaction, we try stuffing still more into our days, never realizing that we are taking the wrong approach.

The truth is simple; so simple it is hard to believe. Satisfaction lies with less, not with more. Yet, we pursue the myth that this thing, or that activity, will somehow provide the satisfaction we so desperately seek.

Arthur Lindman, in his devastating book, “The Harried Leisure Class,” described the futility of pursuing more. His research focused on what people did with their leisure time. He found that as income rose, people bought more things to occupy their leisure time. But, ironically, the more things they bought, the less they valued any one of them. Carried to an extreme, he predicted massive boredom in the midst of tremendous variety. That was more than twenty years ago, and his prediction seems more accurate every year.

Lindman, of course, is not the first to discover this. The writer of Ecclesiastes expressed the same thought thousands of years ago. It is better, he wrote, to have less, but enjoy it more.

If you would like to enjoy life more, I challenge you to experiment with me. How could you simplify your life? What could you drop? What could you do without? What could you stop pursuing? What few things could you concentrate on?

The more I learn, the more I realize that fullness of life does not depend on things. The more I give up, the more I seem to gain. But words will never convince you. You must try it for yourself.

39.Arthur Lindman predicted twenty years ago that ______.

A. more things brought more value   B. the more people had, the less they valued them

C. people didn’t like to pursue more  D. massive boredom came from less variety

40.What does the article suggest to make our life happier?

A. To enjoy more things.             B. To buy more things.

C. To sell things we do not need.       D. To get rid of useless things.

41.The passage is probably written to ___________.

A. introduce Arthur Lindman and his book        B. tell the readers what is satisfaction

C. introduce how to simplify people’s life         D. persuade people to simplify their life

Anxiety is the appropriate(适当的)emotion when the immediate personal terror—of a volcano, an arrow, a stab(刺伤)in the back and other disasters, all directed against one’s self-disappears.

       The kind of world that produces anxiety is actually a world of relative safety, a world in which no one feels that he himself is facing sudden death. The anxiety exists as an uneasy state of mind, in which one has a feeling that something unspecified(不具体的)and indeterminable may go wrong. If the world seems to be going well, this produces anxiety—for good times may end. If the world is going badly—it may get worse. Anxiety tends to be without focus; the anxious person doesn’ t know whether to blame himself or other people. He isn’t sure whether it is the current year of the administration or a change in climate or the atom bomb that is to blame for this undefined sense of unease.

       It is clear that we have developed a society which depends on having the right amount of anxiety to make it work…While we agree that too much anxiety is harmful to mental health, we have come to rely on anxiety to push us into seeing a doctor about a symptom(症状)which may indicate cancer, into checking up on that old life-insurance policy which may have out-of-date provisions in it, into having a conference with Billy’s teacher even though his report card looks all right.

       People who are anxious enough keep their car insurance up, have the brakes checked, don’t take a second drink when they have to drive. People who are too anxious either refuse to go into cars at all—and so complicate the ordinary course of life—or drive so tensely and carefully that they help cause accidents. People who aren’t anxious enough take chance after chance, which increases the terrible accidents of the roads.

62.The author holds that      .

     A.anxiety is a good thing                

B.anxiety is a symptom of mental illness

     C.some anxiety can lead to changes for the better  

D.no anxiety is bad for society

63. According to the author, accidents of the road tend to be caused by     .

     A.all those who are too anxious             

B.all those who have anxiety

     C.those who have no anxiety                 

D.those who are not anxious enough

64. The best title for the passage would be     .

     A.One Man’s Thought about Anxiety     

B.The Right Amount of Anxiety

     C.Anxiety and Safety                            

D.Different Attitudes to Anxiety

Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security.

New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night.

The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.

“We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving,” said lead researcher Dr. Daniel Cohen of Boston’s Brigham and Women’s Hospital. But when those who suffer long-term sleep loss become all-nighters, “the harm is increased ten times,” Cohen said.

The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.

It has critically important complicated and unexpected results for anyone who works “crazy hours” and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York’s Montefiore Medical Center. “Don’t think you can just bank up your sleep on the weekend, because it doesn’t work that way,” he warned.

73. People with long-term sleep loss ______.

A. are quicker in thinking                   B. may feel refreshed soon after waking up

C. are surely energetic                         D. can have a strong sense of security

74. Which of the following is the immediate effect of long-term sleep loss?

A. Health problems                             B. Immune system

C. Reaction times                               D. Memory impairment

75. The underlined phrase “bank up” in the last paragraph most probably means ____.

A. pile up               B. pick up              C. add up                     D. build up

 76. The text mainly advises people ______.

A. to sleep more time                          B. to sleep in on Saturday

C. to sleep scientifically                      D. to sleep little on weekend

Compared to people with bad attitudes,people who are cheerful and relaxed are less likely to suffer from colds,according to a new study.“It’s possible that being upbeat helps the body fight illnesses,” says Sheldon Cohen,the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.

In a previous(先前的) study,Cohen and his colleagues put cold­causing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles,coughs,and other cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors,even when medical tests detected those symptoms.

Those findings were interesting,but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead,it was still possible that a person’s underlying personality is what matters. Evidence suggests,for instance,that certain people are naturally more likely to be outgoing and optimistic,with high self­esteem and a sense of control over life. This would mean that who we are,not how we feel,ultimately decides our chances of catching colds.

To figure out which mattered more (personality or emotions),the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period,people got nose drops that contained either cold or flu viruses. Then,each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms,however,differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus,for example,28 percent developed coughs and stuffy noses. On the other hand,those symptoms struck 41 percent of people who had been less upbeat.

68.What would be the best title for the passage?

A.Smiles Turn away Colds             B.An Interesting Way to Beat Colds

C.Be Outgoing and Optimistic to Fight Colds

D.What Matters More,Personality or Emotions?

69.In the previous study,people who showed positive feelings______.

A.didn’t catch colds as often           B.developed cold symptoms more slowly

C.were less likely to have cold symptoms detected

D.were less likely to feel cold symptoms

70.What mainly decides our chances of catching colds according to the new study?

A.Personality.    B.Self­esteem(自尊).  C.Emotions.    D.Attitudes.

71.The underlined word “symptoms” probably means________.

A.something that causes cold        B.something that results in cold

C.signs that something exists,especially something bad

D.changes in your body or mind that show that you are not healthy

The gray-haired lady can’t wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago.

Not all cases of Alzheimer’s disease look like this ,but Alzheimer’s is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75.

It is said that about three percent of the U.S. population over age 65 have Alzheimer’s. In the early stages, people may exhibit short term memory loss. Some may experience changes in personality, easy to be angry .As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs. 

While no one is certain what causes these changes in the brain’s nerve fibers, their effect is certain. Alzheimer’s destroys not only the patients, but also spouses (配偶), friends and families.

What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer’s disease.

    Though many reasons other than Alzheimer’s disease may cause memory loss ,its early diagnosis (诊断) and treatment may delay some of the most serious effects.

    What feeling will you likely experience should a loved one suffer from Alzheimer’s disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn’t remember you are married.

    Life for the Alzheimer’s patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.

72. What can be inferred from the passage about the gray-haired lady?

   A. She has been living with her father.

   B. She was sad about the death of her father.

   C. She can’t search for her father without being watched.

   D. She suffers from Alzheimer’s disease.

73. When people suffer from Alzheimer’s disease, __________.

   A. their families and friends will suffer from the same disease

   B. their families and friends will experience mental sufferings

   C. they will certainly die in 8 to 10 years

   D. they will forget everybody but their spouses

74. Memory loss occurs __________.

   A. from Alzheimer’s disease and nothing else  

B. from sadness ,shock ,anger ,and so on

   C. for a number of reasons

D. with changes in personality

75. From the passage we know that __________.

   A. early treatment may stop Alzheimer’s disease occurring

   B. it is still unknown what causes the changes in the brain’s nerve fibers

   C. nerve fibers in the brain will cause Alzheimer’s disease

   D. when one suffers from Alzheimer’s disease ,he will be buried

If you have to miss one meal a day, which meal will cause you fewest health problems if you don’t eat it? If they have to make a decision of this type, most people (especially very busy people) will choose to skip (not to eat) breakfast.

    However, many experts in the field of health consider breakfast (the meal which “breaks” your “fast---- a period of time without eating anything ” which started the night before) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humour. But many people skip breakfast or replace it with snacks or a cup of coffee for a well-balanced meal. What happens if we ignore the importance of breakfast?

   One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12—83. During the experiment, these people were given a variety of breakfasts, and sometimes, they had to skip breakfast completely. Special tests, including blood tests and endurance tests, were set up to analyze how well the participants’ bodies functioned when they had eaten a certain kind of breakfast.

    The result showed that if a person eats an adequate (充足的) breakfast, he or she will work more efficiently and more productively than if he or she skips breakfasts or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental activity. The study showed that if schoolchildren eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast diet is inadequate .

The study also showed that, contrary to what many people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you are on a diet, skipping breakfast will not help you. You will probably lose more weight if you reduce your other meals.

46. According to the passage, we can safely say _____.

       A. if you skip breakfast, you will not lose weight at all

       B. if you skip breakfast, you won’t eat much for lunch either.

       C. skipping breakfast won’t do a bit of harm

       D. skipping breakfast will help one lose weight

47. In the word “breakfast”, “fast” probably means _____.

       A. “moving quickly”             B. “going without food ”

       C. “unlikely to go fast”            D. “fast food ”

48. Special tests were organized to analyze how participants’ bodies functioned when ______.

       A. they had skipped breakfasts     B. they had had breakfasts

       C. they had eaten special breakfasts     D. they had had all three meals

There is an English saying: "Laughter is best medicine." Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people's health.

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercises. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍受) the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.

As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

63. Doctors have proved the following except that ____________.

A. smiling does good to health                   B. laughter can be tolerated

C. there is a way to reduce pain                  D. laughter can work the muscles in the feet

64. The main idea of the passage is ____________.

A. laughter and physical exercises have similar effects on the human body

B. smile can produce the same effects as laughter

C. pain can be reduced by laughter

D. laughter is best medicine

65. The underlined word "diminish" is similar to____________.

A. test            B. stop           C. reduce            D. increase

66. Doctors hold laughter clinics _____.

A. to give better condition to their patients

B. in order to improve patients' health

C. to make patients smile

D. to prove smile and laughter have the same effect

More Australians are overweight or obese than ever before, and the number is steadily increasing. Around 64 percent of men and 47 percent of women are carrying too much body fat. This means that the chances of obesity-related disorders, such as coronary heart disease(冠心病) and diabetes(糖尿病), is also on the rise. The popularity of crash dieting has caused many misunderstandings about weight loss. Most of these misunderstandings cause unhealthy weight loss behaviors.

A recent research of deaths in the United States from their National Health Nutrition Examination Survey suggests that being overweight may not increase your risk of dying. This finding is contrary to the past research that they thought the numbers of premature death(早死) linked to weight in the year 2000. The findings were that underweight and seriously obese people have an increased chance of dying compared with normal weight people. Interestingly, however, being overweight is related to a slightly lower chance of dying for your age. The effect of obesity on death rate may have reduced over time, perhaps because of improvements in public health and medical care. The authors say that body weight may not be such an important risk factor for premature death and that fitness, while smoking and too much fat in your diet may be more important.

65. If a person carries much fat, he or she _______________ .

knows how to keep healthy better than those who don’t

should lose weight as soon as possible to keep healthy

will surely suffer from both coronary heart disease and diabetes

might suffer from some diseases related to obesity

66. The underlined phrase “is contrary to” in the second paragraph probably means ___________.

       A. agrees with                                           B. disagrees with

       C. proves                                                 D. combines

67. According to the recent research of deaths in America, ______________ .

underweight people will live longer than those overweight people

dying at an early age is connected with overweight

being overweight doesn’t necessary lead to premature deaths

being overweight is healthier than normal people

68. We can infer from the text that _____________ .

the writer wants to persuade people not to lose weight

misunderstandings about weight loss are more serious than ever

much progress has been made in public medical condition

the cause of premature deaths is heavy smoking
