Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is related to illness is not a new discovery. In 1945, about 68 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

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.
小題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.
小題2:Which of the following statement does the text support?
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.
小題3:We can conclude from the text that _______.
A.the fat in mice's belly was reduced because of the relaxing environment
B.a(chǎn) 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
小題4:What’s the main idea of the text?
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.

Weighed down by study? Pushed to the limit by the fast pace of life ? Frightened by the possible war ? Well, you’re not alone. Men and women in France are seeking relief using the world’s best medicine-----laughter.
In the past year, more than 15 laughter clubs have been set up across the country. People of all ages go to release their stress with an hour group laughs. “People telephoned me and said they have forgotten what it is to laugh. They want to find a place where they can escape all their problems for a while. So they come,” said 40—year—old Jocelyne Le Moan. She usually takes a class of around 60 people through a series of laughter techniques.
Her pupils range from teenagers to 70 years old, but most are middle---aged white collars seeking 60 minutes of relaxation at the end of a busy day. Le Moan takes them through the “Lion Laugh”and the “Laugh Contest”, where participants “speak”to each other in different ways. And instead of talking, they break into fits of laughter. At the end there are 15 minutes of “meditation”, when they lie on their backs and let the laughs burst out of their mouths.
“I love it. It’s an experience that has changed my life. Through it I rediscovered the child’s laugh inside me,”Said Romain Jouffroy, 24. “US President George W. Bush should give it a try. He has lost his laugh,”she joked . Like Jouffroy, many laughter club members find themselves changed into children again, and why not ? The average preschooler laughs up to 400 times a day.
The average adult only a day seven to 15.
The physical benefits of laughter are already well—recognized. Doctors say the act of laughing releases good chemicals into the blood—stream, while the quick breathing that accompanies it helps massage(按摩)the digestive organs and strengthens the heart.
“A full hour is like having your inside go jogging!One finishes out of breath, but feels revitalized(產(chǎn)生新活力. And on top of that , you’ve had a laugh,”said doctor Alexisd’ Estaing.And many participants in Paris also emphasize the psychological benefits. They believe that laughter is a way of making oneself feel more confident.
小題1:Which of the following is not included among the benefits of laughing?
A.It can make people rediscover their children’s laugh.
B.It can release good chemical into blood streams.

A.Jocelyne Le Moan is a teacher of the club.
B.the members are mostly middle---aged white collars.
C.people always need some way to relax in life.

C
If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast ( the meal which “break” you “fast” ) to be the most important  meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (營(yíng)養(yǎng)) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants(參加者) included both males and females who ranged in age from 12 to 83. The results showed that if a person eats an adequate(豐富的) breakfast, he or she will work more efficiently(效率高地) and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental(腦力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast is inadequate(不豐富).
The study also showed that contrary to what people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals.
小題1: According to experts, breakfast is the most important meal of the day because _____.
A.a(chǎn) good breakfast breaks you down fast
B.you’ll lose weight quickly if you skip breakfast
C.breakfast provides what a person needs to work
D.a(chǎn)fter a long night, you’ll feel very hungry
小題2:The underlined part “substitute a cup of coffee for a well balanced meal”(Para. 2) probably means _______.
A.to exchange a cup of coffee for a well balanced meal.
B.To drink a cup of coffee instead of a well balanced meal.
C.To change a cup of coffee into a well balanced meal.
D.To regard a cup of coffee as a well balanced meal.
小題3:The example of school-children in para.3 shows that _______.
A.school-children will be quick and attentive all day if they eat breakfast
B.a(chǎn) proper breakfast will make mental workers more efficient
C.fruit, eggs, bread and milk are the best breakfast for mental workers
D.school-children who have breakfast are much brighter than those who don’t
小題4:Which of the following is NOT true according to Para. 4?
A.Some people skip breakfast because they want to be slimmer.
B.Most people who skip breakfast actually eat more for lunch.
C.People put on weight because they eat too much breakfast.
D.Skipping breakfast won’t help people who want to lose weight.

Ann Whimey, a sophomore(大學(xué)二年級(jí)學(xué)生) at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer."
The young student was experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the great nervousness. though poor scores are often a result of poor study habits, sometimes test anxiety causes low scores. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.
Special university counseling(咨詢) courses try to help students. In these courses, counselors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the test shows their anxiety is high, the students can take courses to help them deal with their nervousness. These courses teach students how to relax their bodies. By controlling their nervousness, they can let their minds work at ease, learn information, then come out without difficulty in a test.
An expert at the University of California explains, "With almost all students, relaxation is felt after taking our program. Most of them have better control during their test. Almost all have some improvements. For some, the improvement is very great.
小題1:The title of the passage should be                        
A.Tests at college
B.Anxiety and Tests
C.How to Get Rid of Anxiety

We have proof that you become what you eat. When you know the effects of different types of food, you can use your knowledge well and eat what you want to become.
Food has an impact on our physical and mental health. Have you ever heard any of the following advice?
Lettuce (萵苣) or milk can make you sleepy.
To stop feeling sleepy you should eat peanuts or dried fish.
Everyone has their own advice to give, which they have read about or have been told by older relatives. Some of these pieces of advice seem to contradict each other.
Eating chocolate makes you fat and gives you spots.
Chocolate contains the essential minerals: iron and magnesium (鎂).
What we need to figure out is what type of chocolate to eat to get the benefits and how much of it to eat. We can do this by reading the list of ingredients (原料) on the chocolate bar package. Exactly how much real chocolate is in there? And how much of that do we need to eat to get the benefits of the minerals it contains?
Future restaurants might be named after the physical or mental state they hope to create. Their menus will list the benefits of each dish and drink. Some restaurants have already started this concept, and list the nutritional (營(yíng)養(yǎng)的) content of their dishes on the menus.
Let’s take the restaurant “Winners” as an example. Their menu would list dishes specifically designed to help you win sports competitions. Or you could choose the Go-faster salad, which is a large bowl of mixed raw vegetables in a light salad dressing, giving you energy without making you gain weight. And what kind of dishes do you think would be on the menu at the “Clever Café”?
So what’s going to happen to hamburgers and biscuits? Will the concept of eating food, because it’s tasty, go out of fashion? Of course not! Junk food is also changing. If ice-cream is not good for children, can’t we give them fat-free, sugar-free tofu ice-cream? Unhealthy food is going out of fashion, so brands are changing. We are told not to drink cola because of the sugar and caffeine content so cola companies are making sugar-free and caffeine-free drinks. We are told dried fruit is a healthier snack than biscuits so some biscuit companies are making biscuits with added vitamins.
小題1:By saying “you become what you eat”, the writer means that ________.
A.you will become your own food
B.you will know what food is good by its appearance
C.food has an effect on your health
D.you will know the effects of different types of food
小題2:What does the underlined word “contradict” mean in the text?
A.Oppose toB.Help with
C.Have influence onD.Benefit from
小題3:How can we eat chocolate properly, according to the passage?
A.To eat chocolate containing the essential minerals.
B.To read the list of ingredients on the package.
C.To get advice from others before eating real chocolate.
D.To learn how much chocolate we can consume before eating.
小題4:Which is true about the future restaurants?
A.The food in “Winners” can ensure you to win sports competitions.
B.They might list the nutritional content of their dishes on the menus.
C.Hamburgers will disappear in these restaurants.
D.The Go-faster salad helps you go faster.
小題5:The concept of eating tasty food will not go out of fashion because ________.
A.the junk food companies are changing their brand names
B.biscuit companies are making dried fruit
C.junk food will become healthier than before
D.Cola companies are still making cola

Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing (喘息).Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others.
Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma(哮喘), Jane Bums at the Harvard School of Public Health found.
Based on these findings.Bums said that current recommended dose(一劑)of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs.Teens who eat less fruit and don't take in enough fatty acids (脂肪酸) are more likely to have asthma and the signs of breathing difficulty.
Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers.Fatty acids are also found in some nuts as well as some green vegetables'.Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm(痰).
More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks."I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said.
Burns added that there are several different ways to get the necessary nutrients."I think vitamin supplements are fine.I think adding vitamin D to orange juice is fine.But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said.The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings.
小題1:According to the passage, what is the problem with teens who don't get enough nutrients?
A.They are becoming smokers.B.They don't take enough exercise.
C.They eat too much fruit and fish.D.They are likely to have weaker lungs.
小題2:According to Burns, how should teens get the necessary nutrients?
A.By drinking juice as much as possible.
B.By eating more whole foods.
C.By taking vitamin pills.
D.By giving up smoking.
小題3:Which of the following is NOT mentioned by the researchers in the passage?
A.The amount of nutrients teens should take in a day.
B.How teens can take in enough nutrients.
C.Whether poor teens can prove their findings.
D.The fact that teens don't like fish.

A.Poor nutrition hurts teens' health.B.Teens lack proper nutrition.
C.Teens are easy to suffer from diseases.D.More fruit help keep teens healthy.

Eating a diet high in processed food increases the risk of depression, research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food,which includes lots of fruit, vegetables and fish,and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat,refined grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58% higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for. He also pointed in a paper that a Mediterranean diet was associated with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood of you eating a Mediterranean diet is not very high.
Dr.Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people's diets were becoming increasingly unhealthy. The UK population is consuming less nutritious, fresh produce and more saturated fats and sugars.
小題1:The text is mainly about         .
A.the increasingly unhealthy diet of the UK population
B.the link between processed food and depression
C.the relationship between physical and mental health
D.the emotional state of the British People
小題2:What do we know about the participants?
A.They are of different ages from young to old.
B.They are from different walks of life.
C.They chose the diet they preferred.
D.Their state are also affected by other factors.
小題3:What can we learn from what Dr. Archana Singh Manoux said?
A.It is difficult for most British people to have a Mediterranean diet.
B.The Mediterranean diet is the most healthy in the world.
C.Many studies have been done on the Mediterranean diet before.
D.The Mediterranean diet is not good for depression.
小題4:Dr. Andrew McCulloch agrees that         .
A.our diets are closely related to our mental health
B.the present study needs more facts and other information
C.the UK population will become ill in the near future
D.more saturated fats and sugars should be taken in
小題5:Why might the author have written this text?
A.To tell people what a healthy diet actually is.
B.To prove people’s diets are increasingly unhealthy.
C.To encourage people to cut down on processed food.
D.To introduce some experts on the research team.
