How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread fallacy(谬误) of all is that colds caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos(爱斯基摩人) to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.
In the Second World War prisoners at the notorious Auschwitz concentration camp(集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter？Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms(症状).

When Mary Moore began her high school in 1951, her mother told her, "Be sure and take a typing course so when this show business thing doesn't work out, you'll have something to rely on. " Mary responded in typical teenage fashion. From that moment on, "the very last thing I ever thought about doing was taking a typing course," she recalls.
The show business thing worked out, of course. In her career, Mary won many awards. Only recently, when she began to write Growing Up Again, did she regret ignoring her morn," I don't know how to use a computer," she admits.
Unlike her 1995 autobiography, After All, her second book is less about life as an award-winning actress and more about living with diabetes (糖尿病). All the money from the book is intended for the Juvenile Diabetes Research Foundation (JDRF), an organization she serves as international chairman. "I felt there was a need for a book like this," she says. " I didn't want to lecture, but I wanted other diabetics to know that things get better when we're self-controlled and do our part in managing the disease. "
But she hasn't always practiced what she teaches. In her book, she describes that awful day, almost 40 years ago, when she received two pieces of life-changing news. First, she had lost the baby she was carrying, and second, tests showed that she had diabetes. In a childlike act, she left the hospital and treated herself to a box of doughnuts (甜甜圈). Years would pass before she realized she had to grow u p ---again---and take control of her diabetes, not let it control her. Only then did she kick her three-pack-a-day cigarette habit, overcome her addiction to alcohol, and begin to follow a balanced diet.
Although her disease has affected her eyesight and forced her to the sidelines of the dance floor, she refuses to fall into self-pity. "Everybody on earth can ask, 'why me?' about something or other," she insists. "It doesn't do any good. No one is immune (免疫的) to heartache, pain, and disappointments. Sometimes we can make things better by helping others. I've come to realize the importance of that as I've grown up this second time. I want to speak out and be as helpful as I can be. "
【小题1】Why did Mary feel regretful?

With big handbags becoming a key fashion accessory(配饰) for working women, health experts are warning they can also become a key health concern.
Bags for women have become bigger and heavier as designers combine briefcases with handbags and straps have become longer, resulting in many users complaining of neck, shoulder and back problems.
“I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up,”said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas.“We take it over to the scale and weigh it and usually they’re anywhere from 7 to 10 pounds. We’re really going to see women with more and more problems later on if we continue the big purse craze.”
William Case, a physical therapist(临床医生)in private practice in Houston, Texas, urged designers“to place a cute, educational caution tag(标签) on all bags to inform buyers of potential neck and shoulder dangers.”Above all, he suggested correct posture while carrying big purses, keeping the head and shoulders upright. Patients should also often change the size and weight of purses carried.
“The extra-large purses are quite extraordinary. They look beautiful when the women wear them, but I don’t know how aware they are of the potential problems,”Case said.
Placing objects on one shoulder was one of the least efficient(高效率的) ways of carrying a load, according to a professor from Cornell University in New York State.“This causes a great imbalance,”he said.“If a big bag is a fashion accessory, then occasional and symbolic use is fine. If not, then keep it light.”

It takes more than just practice to become an Olympian. Gold medal performances require some serious nutrition. Have you ever wondered what these successful athletes eat to stay in peak shape?
Keri Glassman, a registered dietitian and founder of Nutritious Life Meals, appeared on “Good Morning America” today to give you a glimpse into the diets of some top athletes. Some of their meals could surprise you.
Crazy Calorie Count
Glassman said Olympians eat a lot of food- quantities that for ordinary people would constitute pigging out. One secret of swimmer Michael Phelps’ astonishing performance in the 2008 Olympics in Beijing was consuming as many as 12,00 calories in one day.
Athletes can eat like this and not gain any weight because their workouts are intense. According to Glassman, Phelps’ workouts can burn 4,000 to 6,000 calories in a day, and those calories must be added in order to train the following day.
Snacking Secrets
Some athletes eat strange foods that improve their performance. Yohan Blake, the Jamaica sprinter and 100-meter world champion, has stolen champion sprinter Usain Bolt’s thunder on the track during the Olympic trials. Asked about how he gets his energy, Blake answered that he eats 16 bananas per day ,Glassman said.
Jonathan Horton, the lead gymnast on the Us team, has a blood sugar problem. His solution is honey. When he starts to feel shaky at the gym, he takes honey to boost his energy, Classman said.
Foods for Recovery
What are the best foods to help the body recover after harsh competition?
For Olympic swimmer Ryan Lochte, the recovery meal is grilled chicken breasts with Alfredo sauce, whole-grain spaghetti and a salad with lemon juice and olive oil. Lochte, who recently cut out junk food, candy and soda, has undertaken a strength-training regimen(养生法)that involves flipping tractor tires, and tossing beer kegs, Glassman said.

Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.
Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.
It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes like curry or rich pasta sauces, which may please their partner.
Women still have the strongest long-term influence over the couple’s diet and lifestyle, as they still have the traditional role of shopper and cook in most households.
The report, by Newcastle University’s Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.
The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partner.
Women also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.
Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.
Report author and registered dietician Dr. Amelia Lake said, “The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration.”
【小题1】The underlined word “light” (in Paragraph3) probably means _______.

A little stress is good, since it helps you keep motivated to meet your goals. However, too much stress is bad for your health. Stress needs to be managed in order to prevent anxiety (焦虑). Here are some tips on how to manage stress.
Write it out
Write down everything that seems stressful, and ways to deal with each problem. You’ll find a things-to-do list much easier to manage than having all messed up in your head. Write down the tasks along with the specific times when you can do them.
One task at a time
Give each task all your attention while you’re doing it, and forget the rest. This will keep you from feeling anxious about things you have left to do. Thinking about other tasks only adds unnecessary stress, and can even stop you from doing the task you’re busy with at present. You don’t need to do everything all at once, or on your own. The feeling of being pressed to finish something on time will somehow disappear if someone is there to help you.
Give yourself a reward
Rewarding yourself for what you’ve already done, no matter how small, is a great way to motivate yourself to keep going. It will reduce stress, and make you happier to go on with the next task.
Give yourself a break
Breaks of ten to fifteen minutes are important. Visit a cafe or take a quick walk —anything to take your mind off the work for a while. If you need to stay at work, sit with your eyes closed and imagine a peaceful place or some other relaxing scenes. This will remove the stress from your muscles and mind.

Judging from recent surveys, most experts in sleep behavior agree that there is virtually an epidemic（流行病） of sleepiness in the nation．“I can’t think of a single study that hasn’t found Americans getting less sleep than they ought to,” says Dr．David．Even people who think they are sleeping enough would probably be better off with more rest．
The beginning of our sleep-deficit（lack）crises can be traced back to the invention of the light bulb a century ago．From diary entries and our personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night．“The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark．” By the 1950s and 1960s, the sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock．“People cheat in their sleep, and they don’t even realize they’re doing it,” says Dr．David．“They think they’re okay because they can get by on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally energetic. ”
Perhaps the most merciless robber of sleep, researches say, is the complexity of the day．Whenever pressures from work, family, friends and community increase, many people consider sleep the least expensive item on their programs．“In our society, you’re considered dynamic if you say you need only 5．5 hours’ sleep．If you’ve got to get 8．5 hours, people think you lack drive and ambition．”
To determine the consequences of sleep-deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier．“We’ve found that if you’re in sleep deficit, performance suffers,” says Dr．David．“Short-term memory is weakened, as are abilities to make decisions and to concentrate．”
【小题1】What is the main topic of the passage?

A．The history of people’s sleeping patterns．

B．The epidemic of sleepiness in the modern times．

C．Research on the causes and consequences of sleep-deficit．

D．The minimum of our sleeping hours．

【小题2】Which of the following is Dr．David’s opinion?

A．People’s metal power suffers if they are lacking in sleep．

B．Some people can remain energetic with only 6．5 hours’ sleep a night．

C．If they get 8．5 hours’ sleep, people will be full of drive and ambition．

D．People who think they are sleeping enough are better off than those who don't．

【小题3】People in the 18th and 19th centuries slept about 9．5 hours a night because _______．

A．they had no electricity

B．they knew what was best for their health

C．they were forced by their parents to do so

A．the endless TV programs in the evenings and the internet
