Elderly adults who regularly drink green tea may stay more active and independent than their peers over time,according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals that may help ward off the cell damage that can lead to disease.Researchers have been studying green tea's effect on everything from cholesterol(膽固醇)to the risk of certain cancers,with mixed results so far.
For the new Japanese study,researchers decided to examine the question of whether green tea drinkers have a lower risk of frailty and disability as they grow older.
Tomata and his colleagues followed nearly 14,000 adults aged 65 or older for three years.
They found those who drank the most green tea were the least likely to develop “functional disability”,or problems with daily activities or basic needs,such as dressing or bathing.
Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled,compared with just over 7 percent of people who drank at least five cups fl day.
The study did not prove that green tea alone kept people active as they grew older.
Green-tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more education.lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness.
They also tended to be more socially active and have more friends and family to rely on.
Although it's not clear how green tea might offer a buffer(緩沖劑)against disability,Tomata's team did note that one recent study found green tea extracts(提煉物)seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts,they do contain caffeine and small amounts of vitamin K,which means it could block drugs that prevent blood thickened.
小題1:Which of the following can summarize the passage best?
A.Green tea makes you less active.
B.Green tea makes you less disabled.
C.Green tea makes you more friendly.
D.Green tea makes you more educated.
小題2:The underlined word“ward off”in Paragraph 2 probably means     .

We can slow down aging. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging. His solution is a herbal medicine(草藥)to slow the process of aging.
Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has taken a hint from the ancient Chinese medicine system called “Shen”.
According to Shen, it is the kidney(腎臟)which adjusts the functioning of the body as well as its aging process. It is responsible for the level of activity that the human bodies go through. Studies conducted by Dr. Shen show that herbal medicine based on the Shen system slows the aging process, says a report in the Telegraph newspaper. We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness, wrinkles and so on. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance called Fas. Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young? This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.
小題1:How did Dr. Shen find the solution to the problem of aging?
A.By studying Western medicine.
B.By learning traditional Chinese medicine.
C.By combining both Western and Chinese medicine.
D.By doing research on both Western and Chinese people.
小題2:What plays the most important role in keeping people young according to Shen?
A.Medical treatment.
B.Positive life attitude.
C.People’s good kidney.
D.Level of people’s activity.
小題3:The reason why people become old is that    .
A.their bodies produce T-cells
B.they become weaker and weaker
C.they have reduced strength, loss of hair
D.their bodies are unable to fight diseases
小題4:We can probably learn from the passage that    .
A.producing more low calorie food allows people to keep young
B.it remains unknown how effective Dr. Shen’s herbal medicine is
C.people should try to quicken the production of T-cells in the body
D.the more Chinese herbal medicine people drink, the better for health

Why does the rate of heart attacks increase during the World Cup football finals? How can we help an overweight patient to lose weight? They’re just some of the topics covered in a new book by University of Sussex academics, which is helping student doctors to consider the importance of psychology in medical practice.
Psychology for Medicine is the first textbook of its kind, providing medical trainees and new doctors with all the relevant psychological knowledge they need. Previously, students had to refer to many different books for the relevant psychology.
The book, by Sussex psychologists Dr. Sussex Ayers and Dr. Richard de Visser, has been well received by fellow academics and medical doctors and was finished with the help of the students and staff of the Brighton and Sussex Medical School. The students proofread(校對) the chapters, provided ideas for the content and even modeled for the photographs. The book provides a solid grounding in psychological study relevant to medicine, along with practical tips and advice for practice. One student, Simon Hall, drew cartoons for the book.
The study psychology is important for doctors for a number of reasons. Psychological and physical symptoms are highly related. Up to a third of patients will have psychological disorders, while physical causes are usually only found in around 15 per cent of people’s symptoms. In treatment, a lot of the effect drugs can be due to patients believing they will recover rather than the drug itself.
Dr. Ayers says, “The important thing about this book is that it’s applied science --- it shows why psychology is important to medicine and how we should use it. The book’s presentation is really important. It’s not just lots of theory, but full of tips and advice so that students can take what they learn in the classroom and apply it to real-life situations.”
小題1:The book Psychology for Medicine is mainly written for ________.
A.scientistsB.overweight peopleC.patientsD.student doctors
小題2:What is the third paragraph mainly about?
A.The topics of the book.B.The comments on the book.
C.The contributors to the book.D.The characteristics of the book.
小題3:According to the text, the book Psychology for Medicine _________.
A.is a bit difficult to understand.
B.is mainly about how to lose weight.
C.included tips on training football players.
D.focuses on the importance of psychology in treatment
小題4:We can infer that the text is a(n) ______.

Researchers have announced the result of two studies on the health effects of the drug aspirin.One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack.
The study offered two new results from earlier findings, It said taking one aspirin pili every other day helped only healthy men over the age of fifty.It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(膽固醇)levels.
Earlier in the United States began a major aspirin study in the early 1980s.It included 22,000 healthy men doctors.Ail were between the ages of forty and eighty-four.More than 11,000 of the doctors took a harmless pill that contained no drug.The men did not know which kind of pill they were taking.
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill.139 men who took aspirin suffered from heart attacks.Ten of them died.239 men who did not take aspirin suffered from heart attacks.Twenty-six of them died.
The researchers said the doctors' study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men.They said, however, the result does not mean every man over the mage of fifty should take aspirin.They said aspirin couldn't help men who do not eat healthy foods, who smoke cigarettes and who are fat.The researchers said men who think they wou3d be helped by taking aspirin should talk with their doctors first.
小題1:We may learn that the new use of aspirin is ______.
A.to treat heart disease
B.to reduce the chance of a heart attack in old men

For well over a thousand years, smallpox was a disease that everyone feared. The disease killed much of the native population in South America when the Spanish arrived there in the early sixteenth century. By the end of the eighteenth century, smallpox was responsible for about one in ten deaths around the world. Those who survived the disease were left with ugly scars on their skin.
It had long been well known among farmers that people who worked with cows seldom caught smallpox; instead, they often caught a similar but much milder disease called cowpox (牛痘) . A British doctor called Jenner was extremely interested in this, and so he studied cowpox. He believed that, by vaccinating (給接種疫苗) people with the disease, he could protect them against the much worse disease smallpox. In 1796, he vaccinated a boy with cowpox and, two months later, with smallpox. The boy did not get smallpox. In the next two years, Jenner vaccinated several children in the same way, and none of them got the disease.
News of the success of Jenner’s work soon spread. Vaccination soon became a common method to protect people against other diseases caused by virus, such as rabies (狂犬病), and vaccines were sent across the world to the United States and India.
It took nearly two centuries to achieve Jenner’s dream of getting free of smallpox from the whole world. In 1967, the world Health Organization (WHO) started a great vaccination program, and the last known case of smallpox was recorded in Somalia in 1977. The story of vaccinations does not end there, however. There are many other diseases that kill more and more people every year. Besides, many new diseases are being discovered. The challenge for medical researchers will, therefore, probably continue for several more centuries
小題1:Smallpox was so serious that _________________ by the end of l8th century
A.its death rate was up to ten percent
B.those who caught it were certain to die
C.one in ten people in the world died of smallpox
D.one in ten deaths in the world was caused by smallpox
小題2:Edward Jenner discovered that vaccination with cowpox could ____________.
A.make smallpox much milder
B.stop people from getting smallpox
C.protect people against any disease
D.prevent people’s scars after smallpox
小題3:Which of the following statements is NOT TRUE?
A.The first experiment with cowpox was made by a British doctor.
B.After 1977 smallpox disappeared around the world according to WHO.
C.Vaccination had existed among ordinary farmers before being discovered.
D.Vaccination can be used to protect people in the world against not only smallpox.
小題4:The author of the passage thinks that _________________.
A.vaccinations bring many new problems
B.vaccinations end the spread of diseases
C.there is a long way to go to fight against diseases
D.there is a long way to go to discover new diseases

If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast ( the meal which “break” you “fast” ) to be the most important t meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (營養(yǎng)) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute 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 to 83. The results showed that if a person eats an adequate breakfast, he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental(腦力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate (集中)on their lessons for a longer period of time than if their breakfast is inadequate.
The study also showed that contrary to what 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 want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals.
小題1:According to experts, breakfast is the most important meal of the day because _____.
A.a(chǎn) good breakfast breaks you down fast
B.you’ll lose weight quickly if you skip breakfast
C.breakfast provides what a person needs to work
D.a(chǎn)fter a long night, you’ll feel very hungry
小題2:The underlined part “substitute a cup of coffee for a well balanced meal”(Para. 2) probably means _______.
A.to exchange a cup of coffee for a well balanced meal.
B.To drink a cup of coffee instead of a well balanced meal.
C.To change a cup of coffee into a well balanced meal.
D.To regard a cup of coffee as a well balanced meal.
小題3:The example of school-children in para.3 shows that _______.
A.school-children will be quick and attentive all day if they eat breakfast
B.a(chǎn) proper breakfast will make mental workers more efficient
C.fruit, eggs, bread and milk are the best breakfast for mental workers
D.school-children who have breakfast are much brighter than those who don’t
小題4:Which of the following is NOT true according to Para. 4?
A.Some people skip breakfast because they want to be slimmer.
B.Most people who skip breakfast actually eat more for lunch.
C.People put on weight because they eat too much breakfast.
D.Skipping breakfast won’t help people who want to lose weight.
小題5:The best title of the passage is _______.
A.How to Lose Weight
B.What’s a Healthy Diet
C.Surprising Results of a Study
D.Breakfast – A Meal That Breaks You Fast

When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer(模糊的) than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.
When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.
The image you create for yourself has rather strange proportions(部分); certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.
Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.
If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes (中風(fēng))which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.
小題1:According to the passage the “felt” image       the mirror image.
A.is precisely the same asB.is as clear as
C.often differens fromD.is always much smaller than
小題2:Which the following staterants is NOT true?
A.The felt Image is much more important because it helps you locate new feelings.
B.When you are in bed with your eyes closed, it is not easy to imagine your image.
C.When you move, the “felt” image of yourself starts to become clearer.
D.The “felt” image is not so important as the mirror image.
小題3:If a man loses the ability to recognize his right side,           .
A.he can’t locate the doctor’s touch on his left side
B.he can’t locate the doctor’s touch on his right side
C.he loses his sense of touch on the left side
D.he loses feeling on both sides
小題4:What is this passage mainly about?
A.Stroke victims’“felt” imagesB.Stroke victims’ mirror images.
C.The importance of “felt” imagesD.The importance of mirror images.
