1、You know eating fruit and vegetables does good. But do you know it can also make you look good? People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. Scientists at St Andrews University found eating them slightly increased yellow and red pigments in the volunteers' skin. They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. Increasing their intake of greens by 2.9 portions a day was found to make the person look more healthy and an extra 3.3 portions could enhance their attractiveness, when their photographs were rated by others.
Fruit and vegetables are rich in carotenoids(类胡萝卜素),which are known to protect against cell damage from pollution and UV rays, and can also prevent age-related diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange,it was not known a small increase was perceptible(被觉察)to others—and was seen as appealing.
A camera measured changes to the skin's redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident in three weeks. Using light sensors, the researchers showed these red and yellow hues were linked with the levels of carotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene(番茄红素)—which gives tomatoes and red peppers their red colour—and beta-carotene found in carrots as well as broccoli, squash, and spinach. Skin colour is also affected by chemicals called polyphenols(多元酚),found in apples, blueberries and cherries, which cause blood rush to the skin surface.

2、Sleep deprivation(缺失)is an important hidden factor in lowering the achievement of school pupils, according to researchers carrying out international education tests.
It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected.
In literacy(读写能力) tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group.
Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta.
The analysis was part of the huge date-gathering process for global education rankings, the Trends in International Mathematics and Science Study(TIMSS)and Progress in International Reading Literacy Study(PIRLS)
“I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading. That is exactly what our data show,” says Chad Minnich of the TIMSS and PIRLS International Study Center.
“It’s the same link for children who are lacking basic nutrition,” says Mr Minnich, based at the Lynch School of Education, Boston College. “If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of something more basic. Sleep is a fundamental need for all children. If teachers report such large proportions of children suffering from lack of sleep, it’s having a significant impact. But worse than that, teachers are having to adjust their instruction based on those children who are suffering from a lack of sleep. The children who are suffering from a lack of sleep are driving down instruction.”
That means that even the children who are getting enough sleep are still suffering from this sleep-related lowering.
【小题1】 What did the researchers of Boston College try to find?
A.Why children don’t get enough sleep
B.How many hours children sleep every night
C.The relationship between sleep and test results
D.The relationship between sleep and health
【小题2】Many children suffer from sleep deprivation because _________.

D.modern technological devices consume a lot of their time
【小题3】Which of the following countries has the most sleep-deprived students?
A.Japan B.Malta
C.Finland D.Portugal
【小题4】Why are children who get enough sleep also victims?
A.Because they are disturbed by sleep-deprived students
B.Because teaching is driven down by sleep-deprived students
C.Because they have to spend time helping sleep-deprived students
D.Because the teachers waste time disciplining sleep-deprived students
3、The World Health Organization says there has been a sharp increase in the number of over-weight children in developing countries.In African countries, the WHO says the number of over-weight or obese children is twice as high as it was 20 years ago.Around the world, about 43 million children under the age of five were overweight in 2013.
Overweight and obese children are more likely to become overweight and obese adults.The condition can generate serious health problems like heart diseases.
Francesco Branca is the director of the WHO Department of Nutrition for Health and Development.He says urban lifestyle makes people eat processed food more often, which has a high sugar, fat and salt content.He also says people are gaining weight because of their lack of activities.They travel in cars or other vehicles more than on foot.
The WHO experts say to lower obesity rates is especially complex in countries that also deal with high rates of infectious diseases.
The WHO has some basic solutions for individuals and countries.The organization says you should lower your intake of fat, sugar, salt and processed food and eat more fruits, vegetables and increase physical activity.The WHO says these actions are especially important for children.
And WHO expert Branca says mothers should breastfeed their babies for at least the first six months of life, if possible.More importantly, governments should consider providing vitamins for children and educational campaigns about problems linked to obesity would also help.In his view, government policies should deal with how food is marketed to children and food producers must balance quality and taste with the dangers of sugar, fat and salt."Reducing the number of overweight children will not be easy.The goal is difficult to meet even in wealthy countries." he adds.
【小题1】What is the main idea of Paragraph l?
A.Overweight children in developing countries have increased greatly.
B.Children in developing countries generally weigh too much.

B.food producers should be stopped from marketing, food to children
C.governments should play a necessary role in fighting obesity
D.the number of overweight children decreases easily in wealthy countries
4、Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers conclude that the French tend (易于) to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed (挤出) between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.
After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity - or extreme overweight - among adults is only 6%. However, as American fast food gains acceptance and the young reject (拒绝) older traditions, the obesity rate among French children has reached 17% - and is growing.
【小题1】In what way are the French different from Americans according to Dr. Joseph Mercola?
A.They go shopping at supermarkets more frequently.
B.They regard eating as a key part of their life style.
C.They squeeze eating between the other daily activities.
D.They usually eat too much canned and frozen food.
【小题2】This text is mainly about the relationship between ______.
A.children and adults B.Americans and the French
C.life style and obesity D.fast food and overweight
【小题3】Where does this text probably come from?
A.A health report B.A book review
C.A TV interview D.A food advertisement
5、Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically(心理上的) and physically.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
【小题1】 From Paragraph 1, we learn that ________.
A.diet products fail to bring out people’s potential
B.people are fed up with diet products
C.people have difficulty in choosing diet products
D.diet products are misleading people
【小题2】 One psychological effect of diet products is that people tend to _____.
A.hesitate before they enjoy diet foods
B.pay attention to their own eating habits
C.watch their weight rather than their diet
D.try out a variety of diet foods
【小题3】The purpose of writing this passage is _________.
A.to warn people of the side effect of diet products
B.to tell people how to lose weight
C.to advise people to eat diet products
D.to introduce some diet products
【小题4】Which of the following shows the structure(结构) of the passage?
CP: Central Point P: Point Sp: Sub-point(次要点) C: Conclusion
6、In many sports, physical contact(身体接触) is part of the game. But when athletes hit their heads, the hit can cause concussions(脑震荡).
Concussions have long been a concern for professional athletes, but they’ve become more common among young players too. Between 2001 and 2009, the number of kids under 19 visiting doctors for concussions each year increased by 62 percent.
Engineers are developing new helmets(头盔), and new rules are limiting physical contact in some sports. But are these efforts enough to protect kids’ brains?
Concussions can happen during many types of activities. But sports like football and soccer are especially risky. When you run or jump, your body is moving at an increased speed. A sudden hit causes you to move faster in a different direction.
“It’s like when you’re in a bus and it makes a sudden stop,” says Dr. Kevin Crutchfield, an expert at a sports concussion center in Baltimore, Maryland. “You hit the inside of the bus.”
This hit damages the brain. It affects the way the brain functions. So some sports require athletes to wear helmets. Helmets help reduce the force of a hit. The hard outer shell spreads the force of larger area. Inside a helmet, a plastic or air-filled lining also helps soften the blow.
Steve Rowson is an engineer at Virginia Tech. In his lab, he tests how helmets hold up against different types of hits. No helmet can prevent concussions completely, says Rowson. But he’s found that when wearing a newer football helmet, the player’s head doesn’t gain speed as much after a hit. That lowers the risk of concussions.
Many youth sports teams have set limits on physical contact to reduce the risk of concussions. In soccer, most concussions happen as a result of headers—shots or passes made with the head. That’s why many people think kids shouldn’t head the ball until high school.
These efforts should help, says Crutchfield. But the best way to prevent long-term brain injuries, he says, is to stop playing immediately if you suffer concussion. “Protect yourself today so you can play again tomorrow.”
【小题1】Concussions among young players ______.
A.are rare before 2001
B.seem extremely worrying
C.cause kids to lose interest in sports
D.are mostly caused by wearing no helmets
【小题2】The author mentions the sudden stop of the bus to _____.
A.stress it’s dangerous to ride buses
B.show human brains are easily damaged
C.give a better explanation of concussions
D.remind people to wear helmets while playing sports
【小题3】What does Steve Rowson think of the newer football helmets?
A.They vary a lot in size.
B.They work better than the old ones.
C.They slow down the player’s running speed.
D.They allow the players to move their heads more freely.
【小题4】Dr. Crutchfield suggests that after receiving a concussion, young players should__.
A.never head the ball
B.avoid dangerous sports
C.play other kinds of sports
D.stop playing the sport for a while
7、D
Losing weight comes with a lot of health benefits—including making your brain sharper.
There have been few studies of overweight and cognitive functioning, (认知功能) possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Yet, it turns out that overweight may damage cognitive functions such as memory and attention. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
【小题1】There is less research on overweight and cognitive functions because researchers _____.
A. believe overweight only affects our body
B. have focused on ways to sharpen people’s mind
C. do not consider overweight a main cause for low cognitive ability
D. are clear about the relation between weight and mental functions
【小题2】The result of Gunstad’s study shows that ______.
A. losing weight has little effect on people’s memory
B. losing weight can improve people’s mental functions
C. overweight people are likely to have psychology problems
D. overweight people’s abilities of concentration differ greatly
【小题3】What is Gunstad planning to prove next in his research?
A. Slim people are smarter than overweight people.
B. Healthy diet is better than exercise in losing weight.
C. Traditional ways of losing weight are better than operation.
D. Overweight people will get smarter by taking more exercise.
【小题4】Which of the following is the best title for the text?
A.Body Weight and Health
B.Losing Weight by Operation
C.Ways to Improve Mental Functions
D.Losing Weight to Sharpen Your Mind

Do you love the holidays,but hate the pounds that follow? You are not alone. Holidays are times for feasting and celebrating. Many people are worried about their weight.With proper planning,though,it is possible to keep normal weight during the holidays.Whether it is celebrating at the office party or sitting down for the traditional family dinner,regard eating as a time for tasting a variety of the foods.The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy.
Here are some tips for preventing weight gain and maintaining physical fitness:
Don't skip meals.Before you leave home,have a small,low-fat meal or snack.This may help to avoid getting too excited before delicious foods.
Control portions.Use a small plate (about 10 inches) and put aside the large ones that may encourage you to “load up.” You should be most comfortable eating an amount of food about the size of your fist. Once you have your “tasting” serving,move away from the buffet(自助餐). Doing so will make it less tempting to be eating constantly as your appetite is inspired by the sight of food.
Begin with soup and fruit or vegetables. Fill up beforehand on water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you feel full.
Stick to physical activity. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories.
Avoid high-fat foods. Dishes that look oily or creamy may have a large amount of fat. Choose lean meats. Fill your plate with salad and green vegetables. Use lemon juice instead of dessert or butter.
【小题1】Which of the following is NOT true according to the passage?

10、C
Parties and social gatherings no longer excite us the same way they once did. This is not due to a lack of desire to socialize, but the smartphone.
At parties, more people are on their smartphones than on their drinks. According to a recent International Data Corporation study, well over half of all Americans have a smartphone and reach for it the moment they wake up, keeping it in hand all day. In addition, too much of society is using smartphones while driving and as a result getting into car crashes. 34 percent of teens admit to text while driving, and they confirm that text messaging is their number one driving interruption. People's attachment to their smartphones is unbelievably becoming more important than the lives of themselves and others.
Just as drivers dismiss the importance of focusing while on the road, many people also fail to recognize the significance of human interaction. When with their friends, some people pointlessly check or send text messages in the presence of a friend, which sends a message to that friend the person I am texting is more important than you. In addition, relying on our smartphone to make friends does not give us the same advantage as being able to make new friendships in the real world. Face-to-face conversations will give us much stronger communication skills in the long run.
As many people risk their lives and the lives of people around them just to send a text or mindlessly check their massages, smartphones are in many ways more dangerous to people. The quality of this technology is de-advancing societal achievements and weakening the value of communication. Not only is the smartphone affecting our desire to interact (交流) face-to-face but it is also lowering society's ability to communicate.
