The World Health Organization (WHO) planned to study the relationship between the eating habits of the people and the disease. Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor. The diseased children are usually from one to four years old. As the illness progresses, the child’s stomach becomes swollen by liquid collecting in the body. The skin changes color and may break out in open sores（疼痛）. The hair changes color and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced.
The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches（淀粉）instead of greatly needed proteins. They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives.
The unbelievable thing about kwashiorkor is that the very existence of the disease—which has been killing thousands of children for centuries—was not even recognized in Latin America as recently as ten years ago. The deaths of those children were mistakenly listed as due to other diseases. It was the WHO’s work in Africa that led to the discovery of the problem in Central America.

Eat nuts, live longer. Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective.
Researcher Ying Bao is with the Department of Medicine at Brigham and Women’s Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses’ Health Study, which tracks the well-being of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study.
Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?' The information was updated every two to four years. Bao says the participants were followed for three decades.
“What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying.”
Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death. A serving size is 28 grams.
Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart.
Bao says researchers are planning studies to find out how nuts are beneficial to human health.
The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation.
【小题1】People who often eat nuts ________.
| A．are more likely to live longer than people who often eat fruits |

Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated （使…等同） with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely （oppositely） affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert's advice to reduce sedentary （久坐不动的） activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?
【小题1】Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
| A．beauty should be overweight |
| B．a fat man is usually a cheerful character |
| C．fatness was considered something good at one time |
| D．fatness leads to an increased risk of disease |
| A．go on a diet | B．do regular physical activity |
| C．give up smoking | D．go to the gym |
| A．people who help you do exercise | B．places where you can do exercise |
| C．a kind of shoes | D．a form of vehicles |
| A．an increased risk of diseases | B．a happier life |
| C．a cheerful character | D．a beauty |
| A．how to keep fit and avoid fatness. | B．increased risks for overweight people. |
| C．the dangers of exercise in the gym. | D．the benefit of a balanced diet. |

Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.
Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child's helmet fits properly.
1) If you haven't bought your child's helmet already, you might want to consider one with a rear stabilizer(稳定杆). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.
2) The helmet should fit closely and shouldn't slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it's too big. Try a smaller size. But if the next size down is too small, use the fit pads(护垫). Fit pads come in different sizes and attach to the helmet with Velcro.
3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can't, you need to readjust her helmet.
4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.
5) Recheck the fit regularly.
You should replace the bicycle helmet:
If she has been in an accident with it.
If the buckle(金属扣) breaks or if a piece breaks off.
If it doesn't have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.
If it doesn't fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.
【小题1】Who is this passage mainly written for?
| A．Children. | B．Teachers. | C．Parents. | D．helmet producers. |
| A．The bike-related injury is a serious threat to the children. |
| B．The bicycle helmets must fit properly while the children are biking. |
| C．It’s necessary for the children to wear helmets while biking. |
| D．Many students suffer bike-related injuries every year. |
| A．She must buy a smaller size. |
| B．She can use some fit pads. |
| C．She can put fingers on both temples inside the helmet. |
| D．She must make helmet slide from side to side. |
| A．buy a new bicycle helmet for her |
| B．mend the bicycle helmet himself |
| C．continue to use the bicycle helmet |
| D．throw away the broken buckle |

Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief above was longlived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ.Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many firsttime parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary，Mary Ruebush，an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
【小题1】The kings of France and England in the 16th century closed bath houses because ________.
| A．they believed disease could be spread in public baths |
| B．they thought bath houses were too dirty to stay in |
| C．they lived healthily in a dirty environment |
| D．they considered bathing as the cause of skin disease |
| A．Approving. | B．Afraid. | C．Curious. | D．Uninterested. |
| A．By providing examples. |
| B．By making comparisons. |
| C．By following the order of importance. |
| D．By following the order of time. |
| A．To stress the role of dirt. |
| B．To introduce the history of dirt. |
| C．To present the change of views on dirt. |
| D．To call attention to the danger of dirt. |

According to the survey conducted by some scientists, it is common to have difficulty sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift（轮班）work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap (小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications (药物治疗) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.
【小题1】The purpose of the text is to_____ .

| B．If a good sleep environment is greatly needed for him. |
| C．If he fails to get quality sleep through his own efforts. |
| D．If he has the problem of falling asleep in the daytime. |
| A．night workers need a long time to fall asleep |

In today's fast-paced (快节奏) society, few people take time to enjoy the midday meal．Most of us just rush right through it. We grab a quick salad, or buy a sandwich and eat at our computers, Sometimes, if there is a deadline around the corner, we just skip lunch．
The development of technology hasn't done our eating habits much good either．We are constantly distracted by e-mail, social media, and 24 - hour news．Even when we do sit down for lunch, we are more connected to our hand - held electronic devices．
Long working hours can cause all kinds of health problems, and many developed countries have put in place labor laws specifically regarding the lunch break．These laws give employees the right to take a break during a long work shift, but it's up to them whether they do so or not．
Frank Partnoy, a former Wall Street trader, says that employers should encourage workers to take time off for lunch．This is because long lunch breaks can benefit both individuals and society.
Writing in The Guardian, Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective（认识）． A break from work allows us to think strategically and outside the box．It also puts our daily tasks into a broader context（背景）．
What we eat at lunch is also important．In Partnoy' s opinion, a fast food lunch is more harmful than not having lunch at all． And it's not just about calories and unhealthy food．Recent studies show that fast food also has negative effects on how we think．
However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down, something that hardly can be achieved in a noisy and over — packed fast food chain．
Despite these benefits, some employees might still be unwilling to take time off for lunch．Partnoy's suggestion? Make skipping lunch difficult: Employers could ask workers to fill out a form stating their reasons for skipping the meal．
【小题1】What does the underlined phrase "skip lunch" mean in the first paragraph?
| A．have a quick lunch | B．don't have lunch |
| C．work while having lunch | D．take a lunch break |
| A．Modern technology results in good diet habits． |
| B．Electronic devices make our life comfortable． |

| D．make the workers eat a proper lunch at home |
| A．saves a lot of time for a rest |
| B．affects people's way of thinking |
| C．is better than having no lunch |
| D．makes workers sit down and think |
| A．To warn us not to eat fast food． |
| B．To introduce Frank Partnoy's opinion． |

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism (新陈代谢) that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious（恶性的）circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
【小题1】What is the main purpose of this passage?
| A．To advocate eating more raw and whole foods. |
| B．To tell the differences between raw and processed foods. |
| C．To inform people of the harm of processed foods. |
| D．To warn people of the problem of obesity. |
| A．it is essential for people to protect their vital organs |
| B．foods with natural enzymes help people keep fit |
| C．we’d better be cautious about raw and whole foods |
| D．giving up cooked and refined foods is a new lifestyle |
| A．destroy body’s cells | B．are difficult to digest |
| C．may lead to obesity | D．stop body’s metabolism |
| A．Active approaches to avoid acid. |
| B．Different causes of acid accumulation. |
| C．Correct ways to cook raw foods. |
| D．Suitable types of raw and whole foods. |
| A．Processed foods are good for our appetite mechanism. |
| B．Eating the right types of raw and whole foods does good to our body. |
| C．The accumulation of acid in the digestive tract makes digestion more effective. |
| D．Processed foods also comfort the digestive tract. |

“Image is everything.” An entire industry has been built upon the concept that image is everything, but an appealing image isn’t enough when there’s no substance behind it.
First of all, one should consider how important image is in selling products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. But if the product or service doesn’t live up to it, customers will be very dissatisfied. The recent scandal (丑闻) about the Arthur Andersen accounting firm showed that behind that image, it had unfair business practices under the table. Despite the previous positive image, the firm is being accused of criminal actions. Although the image had been nearly perfect, the reality behind the image has led to its downfall.
Similarly, personal consultants(顾问) can build up a very positive public image for politicians and movie stars in the view of the general commons. But once again, history is filled with examples of both that fell from grace (体面) like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind it, failure is close.
To conclude, it’s clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation(等式). What lies behind that image is every bit as important as the image itself — the person or product must live up to that image or there’s little chance for long-term success.
【小题1】The downfall of the Arthur Andersen accounting firm is due to ______.
| A．its dishonesty in business |
| B．its bad management |
| C．its previous images |
| D．its poor service |
| A．their images were not well built up |
| B．they failed to live up to their images |
| C．they felt much pressure from the public |
| D．they paid little attention to fame and fortune |
| A．image is the basis of everything |
| B．truth and image are equally important |
| C．truth goes hand in hand with image |
| D．image holds the key to success |
