The Healthy Habits Survey shows that only about one third of American seniors(年长者) have correct habits. Here are some findings and expert advice.
1.How many times did you brush your teeth yesterday?
·Finding：About 33% of seniors brush their teeth only once a day.
·Step：Remove the 300 kinds of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2.How many times did you wash your hands or bathe yesterday?
·Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number that doctors advise.
·Step：We touch our faces around 3,000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
·Finding：Seniors are not fighting germs as well as they should.
·Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge（海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm, in the winter especially, we wear quite out off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that my life has its  too.
One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma(哮喘), and  the air is so  that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it became of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.
Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or entertainment(娱乐活动). Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising --- and , what is more, shops are often only a short walk away.
Is life better then, in the city? Perhaps it is , when you are in your teens(十几岁)or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.

Doctors say obesity，also known as severe overweight，is a complex condition.A doctor may advise medical interventions(医疗干预) in addition to changes in behavior.But experts say the more successful weight­loss plans include a well­balanced diet and exercise.
People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use.To lose weight，you can reduce the number of calories you take in，or increase the number you use，or both.Experts at the National Institutes of Health say to lose weight，a person should do some moderate or intensive physical exercise most days of the week.This could include fast walking，sports or strength training.
A recent study looked at four of the most popular dieting plans in the United States.Researchers at Stanford University studied more than three hundred overweight women，mostly in their thirties or forties.Each woman went on one of the four plans：Atkins，The Zone，Ornish or LEARN.The women attended diet classes and received written information about the food plans.At the end of a year，the women on the Atkins diet had lost the most，more than four and a half kilograms on average.
Christopher Gardner led the study，reported in the Journal of the American Medical Association. He said the Atkins diet may be more successful because of its simple message to lower the intake of sugar.Also，he said the advice to increase protein in the diet leads to more satisfying meals.
But last week，another report suggested that only a small minority of people have long­term success in dieting.Researchers at the University of California found that most dieters regained their lost weight within five years.And often they gained back even more.But those who kept the weight off generally were the ones who exercised.

The World Health Organization and several other United Nations agencies are calling for a major new effort to fight malaria, tuberculosis and AIDS. These three infectious diseases killed almost 6 million people last year. That is about 10 percent of the total number of deaths around the world last year.
The WHO and UN agencies released a new report at the World Economic Forum in New York City earlier this month. The document says that deaths around the world from malaria and tuberculosis could be cut in half by the year 2010. It also says the number of deaths from AIDS could be reduced 25 percent within that same time period.
The report is called “Calling Up the Response to Infectious Diseases.” It calls for huge new investments in methods to prevent and treat infectious diseases. Officials say money is needed for research and to purchase drugs. Money is also needed to devices to prevent diseases, such as bed nets. Bed nets prevent mosquitoes that carry malaria from biting people while they sleep.
David Heymann, director of the infectious disease program at the World Health Organization, says that providing effective drug treatments is important for improving peoples’ health and economic well – being. Reducing disease can also help improve economic growth in developing countries.
The WHO report also describes successful health programs in developing countries. In Peru, for example, the number of tuberculosis cases was cut in half by increasing the treatment to control the disease. In Vietnam, malaria was reduced 97 percent through the use of bed nets. And in Uganda, cases of the virus that causes AIDS were cut in half among pregnant women and children through the use of anti – AIDS drugs.
This new international health campaign is estimated to cost about 12,000 million dollars a year. So far, officials say the campaign has about 2,000 million dollars. The WHO says the campaign will need stronger relationships among government, private aid agencies, and drug companies to succeed.

American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations.
From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. “With regards to physical levels, we didn’t find much of a difference between rich and poor countries,” Guthold said, “Growing up in a poor country doesn’t necessarily mean kids get more physical activities.”
The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary.
The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country aside from Zambia.
Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.
People show deep concern for kids’ lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated（认为）that urbanization could be a factor as well as easy access to cars and TVs.
小题1:If you are sedentary, you ____________.   
A．are a diligent student spending much time doing homework
B．have at least an hour of exercise outdoors 5 days a week.
C．like watching TV and playing computer games

小题2:Which of the following statements is true as to Guthold’s finding?
A．Most children around the world don’t meet the exercise recommendation.
B．Girls in every country are no more active than boys.
C．Children in rich countries relatively get less physical activity.
D．Only 4% of the girls from Egypt are not active in exercise.
小题3:All the following statements are wrong except _______.
A．Children in poor countries get more physical activities.
B．Girls in Egypt are more active than those in India.
C．Couch potatoes are those children addicted to snacks.
D．Children in Myanmar are less sedentary than those in St .Lucia.
小题4:What would the writer be most likely to discuss in detail in the paragraph that follows?

A new study has found evidence of aggressive (攻击性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.
The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.
Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.
“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”
The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.
The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.
Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (维生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.
小题1:The underlined word “cure” in Paragraph 1 probably means ______.
A．a medical treatment B．a kind of vitaminC．a kind of germD．a kind of rice

小题3:Why did Christian Eijkman raise some chickens?
A．To eat them.
B．To carry out his experiments.
C．To give the Javanese a surprise.
D．To make money by selling them.
小题4:If a person doesn’t get enough vitamins in his diet, he’d better ______.
A．eat more riceB．eat more meatC．eat some chicken D．eat vitamin pills
小题5:We can learn from the passage that ______.
A．beri-beri was caused by chickens
B．the Javanese didn’t like vitamins
C．Christian Eijkman’s experiment was successful
D．the Javanese’s disease was caused by a kind of germ
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.
小题1:The purpose of the author in writing this passage is to ______.
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
小题2:The underlined word “stunning” means ______.
A．interesting 　B．strangeC．significant　D．amazing
小题3:According to the text，more exercise ______.
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
小题4:In order to keep brain healthy，we should avoid ______.
A．eating a good lunch B．doing puzzles
C．eating a large supper D．taking aerobic exercise
Why are people interested in eating raw foods or whole foods (天然健康食品) ? One reason is that eating these types of food reduces the risk of acid (酸) accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked 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 overweight. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive system, where it becomes increasingly acidic. 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 (加工食品) 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 the result is weight gain and obesity.
The accumulation of acid in the digestive system 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 circle in its tracks, people need to consume food and supplements that will neutralize 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. One effective way is to choose raw and whole foods appropriately according to your health conditions and personal preferences.
小题1:It can be inferred from Para. 2 that __________.
A．we’d better be cautious about raw and whole foods
B．foods with natural enzymes help people keep fit
C．it is important for people to protect their vital organs
D．giving up cooked and refined foods is a new lifestyle
小题2:Processed foods are unhealthy because they __________.
A．destroy body’s cellsB．harm your stomach

小题3:What is the main purpose of this passage?
A．To warn people of the problem of overweight.
B．To inform people of the harm of processed foods.
C．To advocate eating more raw and whole foods.
D．To tell the differences between raw and processed foods.
小题4:What is likely to be talked about following the last paragraph?
A．Different causes of acid accumulation.
B．Correct ways to cook raw foods.
C．Active approaches to avoid acid.
D．Suitable types of raw and whole foods.
