Office workers should know that long periods of sitting at your desk may be a killer. Scientists have shown a new threat from this lifestyle that they call  “muscular inactivity (肌肉遲鈍)”.
Sitting still for long periods of time leads to the buildup of substances (物質) in the blood that are harmful to health. And exercise alone won’t drive them away.
Millions of people spend their days between car,office desk and the sofa in front of the TV. While the bad influences are well rocognized,it has been thought that they can be changed by regular trips to the gym or swimming pool.
Now researchers say that is not enough. In addition to regular exercise,office workers need to keep moving while they work,by making regular trips to the printer,coffee machine or to chat with workmates.
Elin Ekblom­Bak,an expert on health,says research shows long periods of sitting and lack (缺乏)  of “whole body muscular movement”  are strongly linked to obesity,heart disease and cancer,and a higher risk of death,regardless of (不管) whether they take enough exercise.
“Everyone knows about the health benefits of regular exercise. But what we haven’t realized before is that long­period sitting down carries an extra risk that cannot be dealt with by taking exercise,” Dr Ekblom­Bak said,adding that sitting still should be recognized as a risk to health.
“It is important to have a five­minute break from desk work every 45 minutes. Don’t email workmates—walk across the office to give them the message. Take a coffee break or put the printer in the next room. I am a desk worker and I try to do it. It is not difficult but sometimes you get lost in your work and you forget about it.”
However,more studies are needed to confirm the ill effects of sitting for too long and ways of fighting them. But at present they conclude that  “keep moving”  should be added to the advice to “keep exercising.”
小題1:Nowadays,many office workers wrongly think that________.
A.long periods of sitting has bad influences on them
B.regular exercise benefits them after long periods of sitting
C.they are living a lifestyle called “muscular inactivity”
D.it’s unfair for them to sit in the office for too long
小題2:What does the author suggest office workers should do?
A.Chat with workmates often.

Ann Whimey, a sophomore(大學二年級學生) 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.

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.

Babies are born yogis. Once we were all able to pull our toes up by our ears and laugh about it. Then we aged, got injured, and began carrying stress in our shoulders and back. In short, we lost our balance.
Yoga(瑜伽) is an ancient practice that helps create a sense of union in body, mind, and spirit. It brings us balance. I was seriously out of balance when I started practicing yoga in 1999. I had plantar facilities in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis. I was desperate for exercise. Yoga became my salvation and even enhanced my other fitness activities. I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it.
Yoga becomes part of your physical life. Your body grows stronger, more toned, and more flexible as you move from one pose to the other. I spent a week in Mexico at a yoga retreat, and it was the first vacation on which I lost weight. “Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K.I.S.S. Guide to Yoga. “Because yoga helps maintain a balanced metabolism (新陳代謝), it also helps to regulate weight. Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells.” I do yoga poses throughout the day. After hours at my computer, I stretch my stiff shoulders and arms. When I need a boost of energy, I do energizing poses. When I am feeling exhausted at the end of the day, I do restorative poses.
Yoga becomes part of your mental life. Yoga teaches you to focus on breathing while you hold the poses. This attention to breath is calming; it dissolves stress and anxiety. I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams. You should always leave a yoga practice feeling energized, not tired. If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses. In yoga, you “surrender” to the pose by letting go of the tension.
Yoga becomes part of your spiritual life. Yoga is practiced by people from all religions; it is not restricted to any religious group. Yoga teaches “right” living in how we deal with ourselves and others. As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness. Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga.
小題1:What would be the best title for this passage?
A.What’s Yoga?B.How I Do Yoga Poses
C.The Benefits of YogaD.The Varieties of Yoga
小題2:According to the third paragraph, yoga can help people __________.

小題3:People feel tired after yoga because __________.
A.they consume energy in practicing yoga

Is there anything more important than health? I don’t think so. “Health is the greatest wealth(財富),” wise people say. You can’t be good at your studies or work well when you are ill.       
Speaking about health, I can’t help telling you a funny story.  
An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease.    
He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat at pleasure, drink with measure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day.  
A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.  
“But you know, doctor,” he said, “it’s not easy to begin smoking at my age.”
小題1:The writer thinks that     .
A.health is more important than wealth

The clock rules our lives. The more we try to save time, the less time we seem to have. In every area of our lives we are doing things faster. And many of us live in towns and cities which are getting noisier and more stressful as each day passes. But now a worldwide movement, whose aim is to slow life down, has started. Its supporters are people who believe that a happier and healthier way of life is possible.
The Slow Food movement was founded the day that an Italian journalist, Carlo Petrini, saw that McDonald’s had opened a restaurant in a beautiful square in Rome. He thought it was sad that many people today live too quickly to sit down for a proper meal and only eat much fast food. He decided that he had to try to do something about it and so he started the Slow Food movement. Slow Food has become a global organization ever since and now has more than 80,000 members in 100 countries.
Slow Food also encourages people to eat local and regional food, to use local shops and markets, to eat out in small family restaurants, and to cook with traditional recipes.
The idea of Slow Cities was inspired by the Slow Food movement. The aim of Slow Cities is to improve people’s quality of life. Towns which want to become a Slow City have to reduce traffic and noise, increase the number of green areas, plant trees, build pedestrian zones, and promote local businesses and traditions. Now it has spread to other countries all over the world, from the UK to Japan and Australia. There are now 135 Slow Cities in 24 countries across the world that have been named since founding of the organization in 1999. Gao Chun County, in east China’s Jiangsu Province, is expected to be named the first “Slow City” in China next year.
“Slow Cities are about having a community life in the town,” said a local resident. “It is not ‘slow’ as in ‘stupid’. It is ‘slow’ as in the opposite of ‘worried’ and ‘stressful’.”
But not everybody is happy. For teenagers, who have to go 25km to Norwich, the nearest city, to buy CDs, living in a Slow City is not very attractive. “It’s all right here,” says Lewis Cook, 16. “But if you want excitement, you have to go to Norwich. We need more things here for young people.”
小題1:What’s the aim of the Slow Food movement?
A.To call on people to eat out.
B.To make people enjoy cooking.
C.To drive McDonald’s out of Rome
D.To encourage people to slow down.
小題2:All the following are necessary to be a Slow City EXCEPT ______.
A.reducing traffic and noise
B.increasing the number of green areas
C.building more department stores
D.promoting local businesses and traditions
小題3:From the fourth paragraph, we know that ______.
A.the Slow Food was founded in 1999
B.there is no Slow City in China now
C.Slow Cities are mainly in the UK
D.there are about 24 Slow Cities in the world
小題4:What’s Lewis Cook’s attitude to living in a Slow City?
A.PositiveB.NeutralC.NegativeD.Indifferent
小題5:What would be the best title for the passage?
A.Slow down and you’ll move fast
B.Time flies never to be recalled.
C.Eat slowly and you’ll be healthy.
D.Pay attention to the quality of life.

Increasingly, over the past ten years, people--- especially young people –have become aware of the need to change their eating habits, because much of the food they eat, especially processed food(加工過的食品), is not good for the health. As a result, there has been a growing interest in natural foods: foods which do not contain chemical additives(添加劑) and which have not been affected by chemical fertilizers(化肥), widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple words, this means that the soil has been nourished(給…營養(yǎng)) by unused vegetable matter, which provides it with vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming area.
Natural foods also include animals which have been allowed to feed move freely in healthy pastures(牧場). Compare this with what happens in the mass production of poultry(家禽):there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other sides of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar. This is actually unnecessary food. It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form of calories. There are no vitamins in it, no minerals, and no fibre.
小題1:People have become more interested in natural foods because______.
A.they want to keep healthy
B.they want to taste all kinds of foods
C.natural foods are more delicious than processed foods
D.they want to return to nature
小題2:Chickens raised in poultry farms are all of the following EXCEPT that _____.
A.they are fed on food which is little better than garbage
B.they live in very crowded condition
C.the eggs they produce lack vitamins
D.they are allowed to move about and eat freely
小題3:According to the passage, ______.
A.people can only find sugar to give them energy
B.sugar is bad for the health
C.the use of sugar is habit forming
D.sugar only sweetens food, but provides us with nothing useful
