Doctors say obesity，also known as severe overweight，is a complex condition.A doctor may advise medical interventions(醫(yī)療干預(yù)) 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.

Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet.
Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don’t get your heart rate up within this level—you just aren’t working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include:
* Running
* Walking (at least 4 to 4.5 mph)
* Swimming
* Bikingk3s5u
* Elliptical Training
* Yoga
Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each session. To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include:
* Weight Training
* Yoga
* Resistance Training
* Plyometrics
Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include:
* Stretching
* Yoga
* Pilates
So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible?
【小題1】If your purpose is to _______, you can choose swimming as your exercise form.

A．keep muscles and bones strong
B．build a strong and healthy heart
C．keep body flexible
D．reduce risk of injuries and pain in joints and muscles
【小題2】After reading this passage, we know that ________.
A．Yoga is really better for people than running
B．The three kinds of training have links with one another
C．Flexibility training helps you build up your muscles
D．The more exercise you do, the better
【小題3】Which of the following is closest in meaning to “session” in Paragraph 3?
A．meeting B．gathering C．term D．period
【小題4】The paragraph following this article may discuss_______.
A．how to build up our strength
B．how to choose an exercise type
C．how to find a good workout dealing with two or three of these goals
D．how to be more flexible

There was a sweet smell of incense (香) in the air as the well­muscled man moved his legs into a position well behind his head.It was something that the human body really should not be able to do.But what else would you expect at the First World Yoga Championships?
On September 25，the world’s leading yoga experts arrived in the US to find out who was the best.But the real prize was to turn yoga into a proper Olympic event.
“Yoga is a combination of bodybuilding，Miss World，Mr Universe and gymnastics，” said championship organizer Bikram Choudhury.“There are some 70 people from more than 20 countries competing in this event.Why not have yoga at the Olympics？”
The public cannot decide whether or not Choudhury’s dream will come true.But he is right about one thing：yoga has become popular with young and old people all over the world.In the US alone,15 million people practise yoga.Everyone is at it，including Madonna and Ricky Martin.
Yoga started in India more than 5,000 years ago.The name means “to join together”．That is to bring the body and mind together into one pleasing experience.The whole system of yoga is built on three things：exercise，breathing and meditation (沉思)．
The yoga that we know today is mostly physical yoga.It’s seen as a type of exercise，but is different from sports like football or running.When we do yoga，we move our body into positions that stretch the muscles and joints，making them stronger.
One of the best things about yoga is the fact that everyone can do it.To women，it means a flat stomach，more shapely legs and a graceful body.To men，it is a way of becoming stronger and more athletic.
There are also specially­designed yoga classes for pregnant women or children suffering from mental disabilities，such as autism (孤獨(dú)癥)．As for teenagers，meditation and simple breathing exercises can help them learn to calm down，relax and concentrate better.But teenagers under  16  are  not supposed to do the body exercises as it could have a bad effect on their natural growth.

I know what you’re thinking: pizza? For breakfast? But the truth is that you can have last night’s leftovers in the a.m. if you want to.
I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don’t have time, others think they’re “saving” calories, still others just don’t like breakfast food.
But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R. D., who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers—it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
【小題1】The word “l(fā)eftovers” in Paragraph 1 probably means _________.

A．food remaining after a meal
B．things left undone
C．meals made of vegetables
D．pizza topped with fruit
【小題2】What can we infer from the text?
A．Working women usually have breakfast in a hurry.
B．Many people have wrong ideas about breakfast.
C．There are some easy ways of cooking a meal.
D．Eating vegetables helps save energy.
【小題3】The text is written mainly for those ________.
A．who go to work early
B．who want to lose weight
C．who stay up late
D．who eat before sleep

What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure(暴露，接觸) to loud music, and both now wear hearing aids（助聽器） as a result. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary（暫時(shí)） hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells（細(xì)胞） somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分貝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume.'? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather."I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "

Levels of Common Noises
Normal conversation                            50 — 65 dB
Food blender                                  88 dB
Jet plane flying above a person standing outside      103 dB
Rock band during a concert                      110 — 140 dB
【小題1】From Paragraph 1, we can learn that ___________                  .
A．loud music is a major cause of hearing loss
B．famous people may have hearing problems
C．teenagers should stay away from school bands
D．the problem of hearing damage is widely known
【小題2】In Paragraph 3, the underlined word "recondition" means__________ .
A．not to be seen B．to fill with sound
C．to become larger in size D．to make good again
【小題3】The purpose of the chart at the end of the article is to show__________   .
A．a(chǎn) list of harmful sounds
B．the effect of rock concerts
C．the noise levels of sounds
D．relationship between daily activities and hearing loss
【小題4】Which of the following statements will Dr. Sam Levine probably agree?
A．When your ears feel warm, your hair cells are dead.
B．Drummer Andrew Sather gives good advice.
C．Many are at the risk of losing hearing.
D．Doctors know how to deal with hearing loss.

Bad teeth can be painful and even be deadly. Infections of the gums(牙齦) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12­year­old boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉質(zhì)), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
【小題1】According to the passage，what is the function of fluoride?

A．Making the surface on teeth much cleaner.
B．Protecting gums from being infected.
C．Keeping holes on teeth from forming.
D．Slowing down bacterial growth and acid production.
【小題2】The underlined phrase “interfere with” in Para.5 probably means “________”．
A．do harm to B．a(chǎn)ccount for
C．contribute to D．stand for
【小題3】What is the purpose of the author in writing the passage?
A．To warn us of the deadly infections of gums and teeth.
B．To introduce the advantages of fluoridated toothpaste.
C．To draw our attention to the dental care of young children.
D．To present the research results about dental care.

Putting in water fountains (飲水器) 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 nutritionist(營養(yǎng)學(xué)家) at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage consumption(飲料消費(fèi)量).
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 the different groups. But by the end of the school year, children in the schools with water fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.
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 (食欲). 
【小題1】What do we know about the survey from the passage?

A．The teachers were also encouraged to drink water.
B．The students surveyed were all overweight.
C．It surveyed children in the countryside.
D．It lasted for a whole school year.
【小題2】 What can be learned from the last paragraph?
A．Drinking water certainly decreases appetite.
B．Further research is needed to confirm the finding.
C．The experts will encourage all the students to drink water.
D．Why students drinking more get less pounds will be clear soon.
【小題3】 What would be the best title for the passage?
A．Schools with water fountains
B．Drink more water and become thinner
C．Water fountains at schools help kids stay thin
D．Water consumption at some German schools
