model to predict how just three grams less a day would affect heart disease in the United States.
The result:10% fewer heart attacks.8% fewer storkes.4% fewer deaths.11% fewer new cases of
heart disease. And 240 billion dollars in health care savings.
Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of
California San Francisco was the lead author. She says people would not even notice a difference in
taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at
Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium(钠),which is how foods may list their
salt content.
The government says the average American man eats ten grams of salt a day. The American Heart
Association advises no more than three grams for healthy people. It says salt in the American diet has
increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can
mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction
Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government
interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list
calorie information. Now a study by the Seattle Children"s Research Institute shows that the calorie
information on the menu can influence what parents order for their children.
B. stroke
C. blood pressure
D. heart attack
B. 900,000
C. 100,000
D. 92,000
B. the American Heart Association suggests less than 3 grams of salt a day for everyone
C. Americans ate no more than 5 grams of salt per day in the 1970s
D. the less salt one eats, the healthier he will be
B. require fast food places to list salt information
C. inform people of the harm that salt does to health
D. put pressure on food companies and restaurants
B. Bloomberg is very successful in his career
C. parents must pay great attention to calorie information
D. a new study is being done about calorie information

举一反三
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 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
(消耗) 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 (标签).
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 (抵
抗) 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.
B. people have difficulty in choosing diet products
C. diet products are misleading people
D. people are fed up with diet products
B. hesitate before they enjoy diet foods
C. pay attention to their own eating habits
D. watch their weight rather than their diet
B. it costs a lot to lose weight
C. diet products bring no pain
D. diet products are free from calories
C. are short of chemicalsD. provide too much energy
a hospital, but all the advanced equipment there shows that there is nothing wrong with you.
Then, consider this: you might be in a state of sub-health (亚健康). Sub-health, also called the third
state or gray state, is explained as a borderline(界限) state between health and disease.
According to the survey by the National Health Organization, over 45 percent of sub-healthy people
are middle-aged or elderly. The percentage is even higher among people who work in management
positions as well as students around exam-week.
Symptoms include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory.
Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from sub-health, according to some medical experts, is to form
good living habits, alternate work and rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements -- vitamins and other elements that are important to
the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause
unhealthy changes in the digestive tract (消化道). They also say that a balanced diet is very helpful in
avoiding sub-health.
B. When you are in a state of sub-health, you should go to see a doctor and buy some medicine.
C. When you are in a state of sub-health, you should have yourself examined in foreign countries.
D. When you are in a state of sub-health, you should find out the reasons and relax yourself.
B. they have lost their living hopes
C. they have more pressure in life and work
D. they begin to get older
B. sleep more
C. form good living habits
D. take more medicine
B. cause to take place
C. keep oneself busy with
D. get tired of
阅读下面一篇短文,从所给选项中选出最恰当的句子,并将其字母标号填在相应的横线上。选项中有两项为多余选项。
something that you can"t sleep at night? 1 This worry in your mind can made your body feel bad.
You may feel angry, frustrated, scared, or afraid-which can give you a stomachache or a headache.
2 Good or normal stress might happen when you"re called to answer a question in class or when
you have to give a speech. This kind of stress that can help you to get things better done. 3
But bad stress can happen if the stressful feelings keep going over a long time. You may not feel
well if your parents are fighting, if a family member is sick, if you"re having problems at school, or if
you"re going through anything else that makes you upset every day. 4
5 That means making good decisions about how to spend your time. If you"re only dealing with
school stuff and have no time to play, you can get stressed. Make sure you keep yourself in mind:
Sleep, Exercise , Leisure(休闲),and Food. If you take care of yourself and get enough sleep and food,
and if you exercise and leave time for fun stuff, you"ll probably be less stressed out!
B. Can you tell a kind of stress from another one?
C. The best way to keep stress away is to have a balanced life.
D. That kind of stress isn"t going to help you, and it can actually make you sick.
E. Since bad stress is harmful for us, you"d better try to change it into good stress.
F. If so, then you know what stress is. Stress is what you feel when you are worried or
uncomfortable about something
G. For example, you may do a better job on your test if the stress pushes you to prepare
well before the test.
in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But
relaxation is essential for a healthy mind and body.
Stress (压力) is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad
thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose
to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand (承受) depends very much on the individual. Some
people are not afraid of stress, and such characters are obviously prime material for managerial
responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in
whatever form, we react both chemically and physically. In fact we make choice between "flight or fight"
and in more primitive days the choices made the difference between life or death. The crises we meet
today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when
such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since
we can"t remove stress from our lives (it would be unwise to do so even if we could), we need to find
ways to deal with it.
B. they believe that work is superior to relaxation
C. they are traveling fast all the time
D. they are becoming busier with their work than ever before
B. knowing the art of relaxation
C. high sense of responsibility
D. having control over performance
B. Stress is always harmful to people"s health
C. It"s easy to change the habit of keeping oneself busy with work.
D. Different people can bear different amount of stress.
B. "find ways to deal with stress"
C. "remove stress from our lives"
D. "establish links between diseases and stress"
B. to try to deal with it
C. to regard it as a vital motivation
D. to find some relaxation
These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?" Most of these old people had no answer. Several replied, "Well, perhaps at age 80."
What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr. Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks.
All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel(血管) system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society.
Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
B. 3
C. 50
D. 30
B. are too old to work in the fields
C. are still working in the fields
D. benefit from physical work
B. Having been married for 90 years.
C. Hard physical work.
D. Having no intentions.
B. is seriously polluted
C. is rich in oxygen and pollution-free
D. is extremely smelly
B. Stress and pressure.
C. Daily hard work.
D. Good genes.
