Elderly people who drink several cups of green tea a day are less likely to suffer from depression, probably due to a "feel good" chemical found in this type of tea, Japanese researchers said.
Several studies have    1 drinking green tea to lessening psychological problems and Kaijun Niu, of Tohoku University Graduate School, and colleagues found people    2  70 and older who drank four or more cups of green tea daily were 44 percent   3    likely to experience depression.
Green tea is widely  4   in many Asian countries, 5   China and Japan.
Niu's team  6    1,058 relatively healthy elderly men and women. About 34 percent of the men and 39 percent of the women had symptoms of    7 , according to the study that was  8     in the American Journal of Clinical Nutrition.
A total of 488 participants said they    9   four or more cups of green tea a day, 284 said they downed two to three cups    10  and the rest reported having one or fewer cups daily.
According to the researchers, the    11   effect of drinking more    12   tea on alleviating symptoms of depression did not    13  after they factored in social and economic status, gender, diet, history of medical problems and       14 of antidepressants.
There was no   15   between consumption of black or oolong tea, or coffee, and   16    symptoms of depression.
A green tea component, the amino acid thiamine（硫胺素）, which is  17   to have a tranquilizing（镇静的） 18  on the brain, may 19 the "potentially beneficial effect" shown in the current study, Niu noted,   20  that more study is needed.

Cancer is among the top killer diseases in our society today and scientists have found out that stress(紧张) helps to bring it on. It is worthwhile to consider, therefore, what are the causes of stress in our life, and whether we can do anything about them.
Are we underemployed, or overburdened with too many responsibilities? Do we have a right balance of work and leisure(闲暇) in our lives? Are our relationships with family, friends or fellow workers all they should be?
All these things can be a cause of stress, and it is best to face them honestly, and bring our frustrations(沮丧，挫败) into the open. People who have a good row and then forget it are doing their health better than shoes who bottle up their feelings.
If our self-examination has brought any causes of stress to light, let us consider what we can do about them. It is possible to change jobs. We can make more leisure and fill it more happily, if we will accept a different living standard. We can improve our personal relationships by a different attitude. It is we who allow other people to make ourselves unhappy. Often the little things that disturb us are not worth an hour’s anger. The teaching in the Bible “Don’t let the sun go down upon your wrath(愤怒)” is good advice from the health point of view as well as the religions(宗教，信仰).
65. Which of the following statement is TRUE?
A. Freedom from responsibilities helps relieve(减轻) stress.
B. Stress is the direct cause of cancer.
C. The cause of stress are worthy of serious study.
D. Cancer is the number one killer in our society today.
66. According to the text, which of the following people is more likely to suffer from stress?
A. People who have cancer.
B. People who like to quarrel with others.
C. People whose living standard is low.
D. People who have more responsibilities than they can handle.
67.The word “row” in the third paragraph most probably means          .
A. a noisy quarrel                       B. a very loud noise
C. a neat line of things side by side         D. a journey in a boat
68. Which of the following is NOT mentioned as a way to reduce our stress?
A. Changing our jobs.
B. Changing our attitude about little things that make us unhappy.
C. Speaking out about our frustrations.
D. Reading the Bible.

At a young age, her doctor told Patti Wilson she was an epileptic（羊癫疯患者）. Her father was a morning jogger. One day she   31   and said, “Daddy, what I’d really love to do is run with you every day, but I’m afraid I can’t do it.” Her father   32    her to start running.

Everyone knows what a needle is. Of course there are needles and needles: Needles for sewing machines, needles for injection(注射), you name it. But few people think of the wonder : a needle works in the hands of those who practice acupuncture(针刺疗法).
During the past ten years or so, I have been suffering from terrible headache. It seems to be getting from bad to worse these days . Last night I got a sudden pain in my head. It was so terrible that I could hardly bear(忍受)it. Although I swallowed all kinds of pain-killers(止痛药), I didn’t feel any better, It seemed that there was nothing I could do but phone for a doctor.
One of our neighbours happened to be with us. He was not a doctor, but he timidly(胆怯地) offered his help, saying “Do you mind if I tried acupuncture on you? These needles may possibly do you some good.” I agreed. In a moment, he had taken out a few needles from his purse. Without a moment’s delay, he fixed a few needles into the skin on my head here and there, Before long, I felt thoroughly relieved(缓解疼痛).
Just then, the doctor sped through my house and said, “Where is our patient?”

Although we already know a great deal about flu, and although the World Health Organization is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.

There are three kinds of flu virus, known as A, B and C. Flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies （抗体） which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability（可变性） is less developed in the flu B virus, which affects only human beings. Flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918 and 1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence （病毒性）, the ease with which it can be transmitted and the strength of the opposition it encounters （遇到）. Scientists, however, have a reliable general picture of the world situation.

72. Which of the following is the most appropriate title for the passage?

A. Symptoms of Flu B. Man VS Flu Virus

C. WHO: The Major Organization against Flu Virus D. Variability of Flu Virus

73. What does the author say about the flu B virus?

A. B Virus is relatively stable and causes mild infections that do not spread far through the population.

B. B Virus is unstable, and is responsible for the epidemics that cause frequent concern.
C. B virus is extremely unstable and is responsible for some of the worst outbreaks of the disease.

D. B virus has a very developed variability, and it affects only human beings.

74. Which of the following is NOT mentioned as a factor contributing to the extent to which a virus spreads?

A. The strength of the virus. B.The ease with which the virus can be transmitted.

C. The strength of the opposition. D.The immunity the virus can bring about.

75. This article is quite probably ________.

A. a piece of news B. a special science report

C. an introduction to a disease D. a scientific fiction

This is a dangerous world we live in. The numbers of murders goes up every year； people are dying of cancer；more people contract（感染）HIV；more teens are using drugs；etc. You know this because you’ve heard all the statistics on the news. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background, statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous.
For example, several years ago a high school student reported dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors（肿瘤）， is found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening strike. When you think about it, skiing is more dangerous than you might at first think when looking at statistics. If we teenagers are to be left in this world, we had better be able think critically, and form our own views. rather than be easily persuaded by another’s. To be warned is to be prepared.
59．In the first paragraph, what problem does the writer want to warn us?
A. We are now living in a dangerous world.
B. We got a lot of false statistics from the media.
C. There are around us more and more murders, diseases etc.
D. Statistics alone without full background don’t give us an accurate picture of things.
60．Why does the writer use the example in the second paragraph?
A. To show the danger of reporting only part of the information.
B. To argue that high school students are easily persuaded.
C. To prove what is necessary to us might be dangerous.
D. To warn us of the harmful substances（物质）around us.
61．Relative information is often left out because__________
A. relative information is not that important
B. the author is trying to show what he or she says is true
C. too much information will make readers feel confused
D. readers are not able to analyze so much information at once
62．What is the main idea of this passage?
A. Some measures must be taken to protect our dangerous world.
B. We should learn to think critically and look at problems from all sides.
C. The growing trend of reporting only half-truths is getting out of control.
D. Teenagers ought to improve their ability of telling right from wrong.

C
Patients and doctors alike have long believed in the healing (治疗) power of humor. It is claimed that humor not only affects patients’ moods, but can actually help them recover faster.
Several studies seem to support this. Patients in better spirits are known to have higher immune cell counts. Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies.
Despite all this, many researchers are not convinced. They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter. They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first.
Humor in times of stress, however, clearly makes us feel better. On one level, it takes our minds off our troubles and relaxes us. On another, it releases powerful endorphins, a chemical produced by your body that reduces pain.
There are cases where the appreciation of a good joke is indeed directly related to a person’s health. It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe (额叶).
Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list. Subjects with normal brains usually chose endings that were based on a relatively complex synthesis (综合) of ideas. Subjects with specifically located brain damage, however, responded only to slapstick (闹剧) endings, which did not depend on a particular context. When pressed, the brain-damaged subjects saw the logic in the correct endings. They simply did not find them funny.
Of course, humor is largely an individual matter. Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain. However, you might suggest that he lighten up—for the health of it.
63. We can infer from the passage that ________.
A. all researchers have agreed on the healing power of humor
B. people seldom accuse their friends of not understanding jokes
C. the author holds a positive attitude to the healing power of humor
D. reading comics will surely become a popular way of treating diseases
64. Which of the following statements is NOT true?
A. Many researchers are not convinced of the healing power of humor.
B. Patients in bad moods are known to have higher immune cell counts.
C. Optimism in general does seem to be related to better health.
D. People should try their best to cheer up for their good health.
65. Scientists had some people read jokes and asked them to choose the funniest endings from a list to confirm that ________.
A. the brain-damaged people are different from those with normal brains
B. a person with a normal brain usually responds to slapstick endings
C. a person suffering certain brain damage doesn’t appreciate a good joke
D. humor takes our minds off our troubles by releasing powerful endorphins
66. Which would be the best title for the passage?
A. Which comes first, humor or health? B. Humor can cure different illnesses
C. People need humor in times of stress D. Humor contributes to good health

D
The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government's health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.
One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.
In addition, health education plays a key role in improving people's health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one's family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.
However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
67．What’s the best title of the passage?
A．Prevention or Education?    B．Prevention or Treatment?
C．Health or Illness?            D．Exercise or Illness?
68．Which of the following can replace the underlined word “bankrupt’’?
A．Unable to be cured        B．Unable to pay one’s debts
C．Stronger than ever before  D．More successful than ever before
69．We learn from the passage that       .
A．dressing warmly can prevent diseases
B．a balanced diet is cheaper than regular exercise
C．the more health education, the better
D．the government’s health budget should be increased
70．Which of the following shows the structure of the passage?

CP (Central Point) P (Point) Sp (Sub-point次要点) C (Conclusion)
