According to the study, Swiss-banknotes are mostly cotton covered by a nonporous resin(无孔树脂). Banknotes from other countries may be composed of different materials, and this could affect viral transmission. “Whether similar results would be obtained with banknotes from other countries and with different characteristics needs to be studied.” the authors wrote. In an interview with Reuters, Thomas said. “Our studies have convinced us that it is possible to catch the flu from banknotes, but the chances are very, very small and there is no cause for concern among the gneral population,” To be sure, many kinds of frequently touched surfaces could temporarily hide the flu virus. Broadly speaking, scientists consider the risk of transmission in this way to be low. Particularly if hand-washing and other hygiene measures are practiced.
Three things must happen for a flu virus to be transmitted from one person to another via money. First, a person who is infected with the flu virus must sneeze or cough onto the banknote. Next, an uninfected person would need to touch the money while the virus si still present. Finally, that person would need to put his hand in his mouth or pick his nose, says Thomas. The best defense against infection: follow public health guidelines and wash your hands frequently.
49. What does the underlined word “this” refers to in the second paragraph?
A. The time when people stay in a bank.
B. The fact that banknotes may consist of deferent materials.
C. The bank where people draw their money.
D. The country where the banknotes are in circlation.
50. From the last paragraph, we can know that an infected person should ________.
A. pay attention to his personal hygiene B. wash his hands after leaving a bank
C. be monitored at a bank D. not cough at a bank
51. What can we learn from the passage?
A. Any person who touches banknotes will become infected.
B. Different flu viruses stay on the surface of banknotes for different lengths of time.
C. The bank should not allow any infected person to enter.
D. Only banknotes in Switzerland can transmit the flu virus.
52. What is the best title for the passage?
A. Is it Dangerous to Stay in a Bank?
B. How to Avoid Being Infected with the Flu Virus?
C. Can You Catch the Flu from Handling Money?
D. Why Do People Refuse to Use Banknotes in Switzerland?

Sports medicine experts have observed for years that athletes such as long distance runners, especially women athletes, often display a lack of iron. Now a new study by a team of Purdue University researchers suggests that even moderate exercise may lead to reduced iron in the blood of women.
"We found that women who were normally inactive and then started a program of moderate exercise of middle degree showed sings of iron loss," says Roseanne M. Lyle, associate professor at Purdue. Her study of 62 formerly inactive women who began exercising three times a week for six months was published in the journal Medicine & Science in Sports & Exercise.
Iron deficiency is very common among women in general, affecting one in four female teenagers and one in five women aged 18 to 45, respectively. But the ratio is even greater among active women, affecting up to 80 percent of female endurance athletes. This means, Lyle says, that "too many women ignore the amount of iron they take in". Women of child-bearing age are at greatest risk, since their monthly bleeding is a major source of iron loss. Plus, many health-conscious women increase their risk by rejecting red meat, which contains the most easily absorbed form of iron. And because women often restrict their diet in an effort to control weight, they may not consume enough iron-rich food, and are liable to experience a deficiency.
Exercise can result in iron loss through a variety of mechanisms. Some iron is lost in sweat, and, for unknown reasons, intense endurance exercise is sometimes associated with bleeding of the digestive system. Athletes in high-impact sports such as running may also lose iron through a phenomenon where small blood vessels in the feet leak blood.
There are three stages of iron deficiency. The first and most common is having low iron reserves, a condition that typically has no symptoms. Fatigue and poor performance may begin to appear in the second stage of deficiency, when not enough iron is present to form the molecules(分子) of blood protein that transport oxygen to the working muscles. In the third and final stage, people often feel weak, tired, and out of breath - and exercise performance is severely compromised.
"People think that if they"re not at the third stage, nothing is wrong, but that"s not true," says John L. Beard, who helped design the Purdue study. "You"re not stage 3 until your iron reserves go to zero, and if you wait until that point, you"re in trouble."
Beard and other experts say it’s advisable for people to have a yearly blood test. If iron levels are low, talk with a physician to see if the deficiency should be corrected by changing your diet and taking iron-rich foods or by taking iron-added pills.
“Select breads and cereals with the words ‘iron-added’ on the label,” writes sports diet expert Nancy Clark. “This added iron supplements the small amount that naturally occurs in grains.” Clark also recommends cooking in iron pans, as food can obtain iron from the pan during the cooking process.

Doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?
The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.
So while doctors may tell patients they are overweight, the conversation often ends there, said Christine C. Ferguson, director of the Stop Obesity Alliance. Without being told about options for diabetes, she said. “Doctors don’t feel they have good information to give. They felt they didn’t have adequate tools to address this problem.”
The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know at they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.
Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past — and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity-related diseases like hypertension and diabetes.
Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn., which ranks 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re going to be successful with helping your patients lose weight, you’re going to have to talk to them at virtually every visit about their progress, and find something to encourage them about, find progress in some aspect of their care and coach them,” he said.
He acknowledged that many doctors tend to be optimistic.
“Part of this is that there’s this common belief, and doctors are burdened by it, too, that heavy people are weak-willed and just don’t have any willpower and are self-indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”
61．What is most probably the Stop Obesity Alliance, as in Paragraph 3?
A．An organization of doctors specializing in obesity.
B．An organization of patients suffering from obesity.
C．A research group that conducts special surveys about overweight people.
D．A research group dealing with doctor – patient relationship.
62．How many of the patients surveyed have been advised by their doctors to lose weight?
A．About 350. B．About 390. C．About 900. D．1,000.
63．What can be inferred about obesity patients in Paragraph 5?
A．They are not as hopeless as doctors think they are.
B．Most of them have tried hard to lose weight, but in vain.
C．Without their doctors’ constant coaching, there is little chance of their succeeding in losing weight.
D．Most of them have just given up their hope of becoming less heavy.
64．According to the passage, which factor contributes to the lack of dialogue between doctors and patients?
A．Most doctors just never think of warning their patients about their weight problem.
B．Many doctors find it difficult to persuade overweight people to lose weight.
C．Most patients are too weak – willed to do anything about their weight.

Sports can help you keep fit and get in touch with nature .However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

Want to lose weight? Try eating. That’s one of the ways being developed by scientists experimenting with foods that trick the body into feeling full.
At he Institute of Food Research in Norwich, England, food expert Peter Wilde and his colleagues are developing foods that slow down the digestive system, which then sends a signal to the brain that stops appetite. “That fools you into thinking you’ve eaten far too much when you really haven’t,” said Wilde. From his studies on fat digestion, he said it should be possible to make foods, from bread to yoghurt, that make it easier to diet. While the research is still in its early stages, Wilde’s approach to controlling appetite is one that some doctors say could be a key to solving the problem of obesity.
“Being able to switch off appetite would be a big help for people having trouble losing weight,” said Steve Bloom, a professor of investigative medicine at London’s Imperial College, who is not connected to Wilde’s research. Bloom said that regulating appetite through foods is theoretically possible. But Bloom warned that controlling appetite may be very challenging. “The body has lots of things to prevent its regulatory systems from being tricked,” he said.
Wilde’s research makes use of the body’s ways of digesting fat. Fat normally gets broken down in the first part of the small intestines (肠道). When you eat a high-fat meal, however, the body can only digest the fat entirely further down in the intestines, which then causes the body to produce a kind of chemical to stop the appetite.
Wilde’s approach copies what happens with a high-fat meal. He coats fat droplets (滴) in foods with modified proteins from plants, so it takes longer for the chemical that breaks down fat to reach it. That means that the fat isn’t digested until it hits the far reaches of the intestines. At that point, intestinal cells send a signal telling the brain it’s full. Even though the body hasn’t had a high-fat meal, it stops the appetite as if it has. If the fat had been digested earlier in the intestines, no such signal would be sent.
51. According to Wilde’s research, what could people do if they want to lose weight?
A. Eat more bread and yoghurt. B. Trick the body by eating nothing.
C. Have foods with fat droplets coated. D. Control their digestive system strictly.
52. The underlined word “obesity” in Para. 2 most probably means “________”.
A. being too fat B. eating too much food
C. stopping appetite D. being unhealthy
53. What can be inferred about Professor Bloom’s opinion towards Wilde’s approach?
A. It won’t work since the body’s regulatory systems will never be tricked.
B. It is sure to switch off the appetite of people with a weight problem.
C. It sounds terrible because regulating appetite through foods is not practical at all.
D. It’s no that easy to trick the body so more research should be done.
54. Which of the following is TRUE about Wilde’s approach?
A. A kind of chemical is added to make a high-fat meal less fatty.
B. Fat is digested earlier and the body sends a signal telling the brain it’s full.
C. Fat won’t get broken down in the first part of the small intestines.
D. The chemical that breaks down fat will not reach the fat.
55. The passage is written to ________.
A. give advice on how to stop eating high-fat meals
B. introduce a research on controlling appetite
C. discuss the argument between two professors
D. show different ways to trick the body
