Putting in water fountains(饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage(饮料) consumption.
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.[来源:学
Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.

解析试题分析：文章介绍了由Dortmund and Essen两人主持的一项调查研究，要教给学生水的健康元素，这样可以减少学生增胖的可能，这项调查是在两个德国城市的32个学校展开的，在研究初期不同的小组增肥学生的总数没有太大不同，但是在学年结束的时候，大约有百分之三十一的学生都似乎没有变胖，用饮水机的学生的饮水量有所增加，而其它学生基本保持不变，而用饮水机的学生变胖的总数没有其它学校的学生变胖的总数多，专家也不能做出最后的结论，也无法解释为什么学生在鼓励喝水的同时并没有发胖。
【小题1】A综合理解题。由Dortmund and Essen两人主持的一项调查研究，要教给学生水的健康元素，这样可以减少学生增胖的可能，这项调查是在两个德国城市的32个学校展开的，在研究初期不同的小组增肥学生的总数没有太大不同，但是在学年结束的时候，大约有百分之三十一的学生都似乎没有变胖，用饮水机的学生的饮水量有所增加，而其它学生基本保持不变，而用饮水机的学生变胖的总数没有其它学校的学生变胖的总数多，专家也不能做出最后的结论，也无法解释为什么学生在鼓励喝水的同时并没有发胖。这篇文章出自于the journal Pediatrics这本刊物，所以由此可知这本杂志是有关儿童健康问题的，故答案应为D。
【小题2】D细节判断题。At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, 句意为：在研究开始的时候，在不同的分组里面发胖的学生总数没有什么不同，但到了学年结束的时候----由此可知这项研究持续了一年的时间。故答案应为D。
【小题3】D细节理解题。Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.句意为：用饮水机的学生增加了他们水的消耗量从大约三杯到了一天四杯，而其它学校的学生他们的饮水量仍然是平均三杯，但前者在1641个学生里面增学生总数从384到了385个，而后者没有安装饮水机的学校学生在1309名学生中，增胖的总数从339个上升到了364个。所以本自然段讲的是研究的结果，故答案应为D。
【小题4】B综合理解题。The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.句意为：专家还不能做出最后的结论，也不能解释多喝水的学生为什么似乎没有增肥，所以还需要继续研究以证实他的发现。故答案应为B。

For a while, my neighborhood was taken over by an army of joggers (慢跑者). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. "Come on!" My friend Alex encouraged me to join him as he jogged by my house every evening. "You'll feel great."
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I'm not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet have a real pounding (追击) ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say, "I love being out there with just my thoughts" Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn't just the first week: it was practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm enjoying it at the same time. I could never say the same for jogging, and I've found a lot of better ways to stay in shape.

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems unclear. Many people who do a lot of work, such as writing, reading and sewing become near-sighted.
Then people who are far-sighted endure just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism（散光）. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts（白内障）. Long ago these people often became blind. Now however, it is possible to operate on the cataracts and remove then.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle（角度）. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
【小题1】We should take good care of our eyes .
| A．only when we can see well |
| B．only when we cannot see perfectly |
| C．only when we are near-sighted or far-sighted |
| D．even if we can see well or perfectly |
| A．near-sighted | B．far-sighted | C．astigmatic | D．suffering from cataracts |
| A．experience | B．imagine | C．suffer from | D．recover from |
| A．seeing at night | B．seeing objects far away |
| C．looking over a wide area | D．judging distances |
| A．one eye bigger than the other |
| B．eyes that are not exactly the right shape |
| C．a difficulty that can be corrected by an operation |
| D．an eye difficult that cannot be corrected by glasses. |

Having one of those days or weeks when everything seems to annoy you? Even if you do nothing about it, your bad mood(心情) will probably go away after some time. But with a little effort, you can forget it much faster—often within a day or two.
Walk it off
Exercise is the most popular bad mood buster. A person who's in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing the bad mood.
Tune it out
Listening to your favorite music for a while can also make tension go away quickly, because music starts connection with past positive experiences we've had.
Give yourself a paper talk
Stop and listen to what's on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper, the pessimistic(悲观的) messages you've been giving yourself, and then give optimistic answers. (“I still don't have a job.” vs “I have two interviews next week.”)
Reduce your stress
Relaxation techniques are wonderful moodlifters. These include deep breathing, stretching and visualizing(想像), all of which sound complicated(复杂的) but aren't. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to distress is to make a todo list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you're not helpless. You can make changes in your mood and life.
Avoid things that won't improve your mood
TV may not help much: you need to increase your energy level and stimulate(刺激) your mind—something that the TV show “Neighbors” won't do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta(面食), produce calming effects in people who have a desire for them.
【小题1】Which of the following may help us stop a bad mood?
| A．Doing nothing about it |
| B．Exercising and enjoying music. |
| C．Writing down negative thoughts |
| D．Talking about it with neighbors. |
| A．It helps remove bad mood. |
| B．It brings us a new technique. |
| C．It is not complicated to do so. |
| D．It is an area to be easily controlled. |
| A．shows what happens around you | B．does not energize you |
| C．reminds you of eating and drinking | D．produces a calming effect |
| A．Energy Level and Stress | B．How to Beat a Bad Mood |
| C．Bad Mood and Our Life | D．How to Control Your Feeling |

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 (酸性的). 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 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(新陈代谢) becomes inactive, and then 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 |

Work your brain!
Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body’s oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don’t die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks.
Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated. Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It’s very important that we tell people to be physically active and mentally active,” said neurologist Malcolm Stewart.“People cannot stop aging, but you’re able to reduce the damage; you’re able to keep the function up.”
Following are Dr. Stewart’s advice for improving brain health：
| Nutrition | Avoid fast food. Follow the old adage(格言): For breakfast, eat like a king; for lunch, like a queen; for supper, like a beggar. |
| Exercise | Do a combination of stretching aerobic and muscle strengthening every day. |
| Mental games | Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better. |
| A．inform us how the brain works |
| B．give us advice on how to keep the brain healthy |
| C．tell us that the brain plays an important role in our lives |
| D．show how special the brain is to us |
| A．interesting | B．strange | C．significant | D．amazing |
| A．keeps our mind sharp |
| B．helps improve our memory |
| C．gives our brain a rest |
| D．is good for brain cells communicating with each other |
| A．eating a good lunch | B．doing puzzles |
| C．eating a large supper | D．taking aerobic exercise |

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long-term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team’s findings appear in the journal Cell Metabolism, said, “I'm still amazed at the degree of fat loss that occurs.” explaining how new technology had threatened face-to-face socializing, he added, “It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities.” Co-author Dr Lei Cao said，“Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.”
【小题1】What information can we get from the first two paragraphs?
| A．Brown fat stores calories and makes us fatter. |
| B．It doesn’t take long to turn white fat into brown. |
| C．Social excitement helps gain more weight. |
| D．Brown fat can burn energy to produce heat. |
| A．Levels of brown fat can be increased by socializing. |
| B．The mice lacking social life lose more weight. |
| C．The research findings haven’t been published so far. |
| D．Dr Matthew During wasn’t convinced of the result. |
| A．the fat in mice’s belly was reduced because of the relaxing environment |
| B．a sedentary lifestyle and high calories foods influence people’s social life |
| C．surfing the Internet may influence people’s face-to-face communication |
| D．cancer and death are mainly caused for lack of social life |
| A．Brown fat is beneficial to people’s health. |
| B．Socializing is unnecessarily important in people’s daily life. |
| C．White fat can be changed into brown fat. |
| D．Socializing contributes to people’s losing weight. |

If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks (口罩) trying their best to stop the swine flu (猪流感). And the masks aren’t only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask!
But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC’s reporter Sharyn Alfonsi talked with germ (细菌) expert Dr. Elaine Larsen. It turns out that when you sneeze (打喷嚏) the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected (被感染).
However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won’t become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else’s nose, mouth or their mask.
Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often.
【小题1】According to Para.1, in Mexico you can see that ____.
| A．the patients are treated in the open air |
| B．some doctors work in the street |
| C．people speak little to each other in the street |
| D．many people wear masks in the street |
| A．breathing | B．Speaking | C．touching others | D．sneezing |
| A．sick people will be infected |
| B．germs can spread very far |
| C．germs spread very quickly |
| D．few people will be infected |
| A．the mask will be old and worn out |
| B．you’ll love the feeling of wearing it |
| C．germs will be kept away from you |
| D．it will be easy for you to be infected |
| A．Keeping the masks dry. | B．Changing the masks often. |
| C．Choosing very thick masks. | D．Wearing big masks. |

In the past, the affairs happening inside one country had little influence on other countries, even the neighboring ones. Therefore, incidents of food safety only affected and spread within one country, one city, one island or one village. However, with globalization, goods and products can almost flow freely between countries, regions, and continents. So the food safety problem is therefore no longer a national or regional issue, but rather a global one．
In 1997, Avian Influenza caused widespread panic in Hong Kong．It is said that the Avian Influenza originated from Shenzhen. Some Hong Kong people blamed the chicken farm staff on the mainland for the outbreak. The staff was accused of not thoroughly checking the health condition of the chicks under their care. It resulted in Hong Kong people's anger towards chicken farm staff in Shenzhen, whose supposed negligence(疏忽)contributed to the later spread of Avian Influenza in Hong Kong．
Worse still, in Germany, people have been warned not to eat cucumbers until tests can identify the source of a deadly E. coli outbreak. The scare has spread across Europe, with 16 people so far having been killed．In many people's minds, European countries have the strictest standards and checking procedures on their food safety. But the E. coli cucumber incident brought home the reality that it was not an effective defense against such an outbreak．
These diverse food safety issues from various parts of the world are enough evidence that food safety problem is not endemic in China. In fact, food safety is not even directly related to the development level of a place, thanks, no doubt, to the connectivity of our age. If we do not maintain our vigilance(警惕), people's confidence in food safety can be destroyed instantly—even in a developed country
【小题1】Which of the following is true according to the passage?
| A．Nowadays, food safety incidents spread inside one country |
| B．In 1997, Avian Influenza caused great fear in Hong Kong |
| C．16 Germans died of deadly E. coli after eating cucumbers |
| D．Food safety is only related to the developing countries |
| A．serious | B．common | C．urgent | D．unique |
| A．food safety problems spread from one country to another |
| B．the staff of a Shenzhen chicken farm caught Avian Influenza |
| C．the strictest standards protected European people from getting E. coli |
| D．China is a country where food safety problem is related to people's age |
| A．Food Safety Problem Is a Global Issue |
| B．Cucumbers Are Popular in European Countries |
| C．Avian Influenza Originated from Shenzhen |
| D．Food Safety Issues Are Various from Country to Country |
