Do you love holidays but hate the increase weight that follows? You are not alone.
But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report consisted of ten lines, and it cost me $215.
With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.
Do not miss meals. Before yon leave home for a feast(宴會(huì)),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.
Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.
Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables.
If you have a sweet tooth, try mints (薄荷) and fruits. They don’t have fat content as cream and chocolate.
Don’t let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(過多的) calories.

Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them, sense them, without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately, your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(輻射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
【小題1】What is the main idea of the passage?
| A.How to detect nuclear radiation. |
| B.How radiation kill a man. |
| C.The mystery about nuclear radiation. |
| D.Serious damage caused by nuclear radiation. |
| A.Nuclear radiation can cause cancer to human beings. |
| B.Nuclear radiation can be safe to human beings if its level is low. |
| C.Nuclear radiation can be detected by human senses. |
| D.Nuclear radiation is just like common radio waves. |
| A.The hurt cells can stay in the body many years and then grow into cancer. |
| B.It can do harm to a person while the victim isn't aware the damage has occurred. |
| C.Nuclear radiation can kill a person very easily. |
| D.Radiation can seldom kill a person immediately. |
| A.die of cancer after many years | B.die immediately |
| C.have a child who may be born weak | D.a(chǎn)ll of the above |

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes--Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect (反射) on the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands--Hand injuries can happen because the hands are moved in the same way hundreds of times. If you use a keyboard for a long time, follow this rule: Stop sometimes and exercise your hands and fingers in different ways.
Your back--Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back and your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.

Air pollution is a leading cause of cancer and classified among Group 1,or top, human carcinogens (致癌物質(zhì)), said the International Agency for Research on Cancer (IARC), which is the World Health Organization's (WHO) cancer agency, on Oct 17,2013.
The most widely used system for classifying carcinogens comes from the IARC, which places them into five groups. Group 1 carcinogens definitely cause cancer in humans. Group 2A is probably carcinogenic to humans, Group 2B is possibly carcinogenic, the carcinogenicity of Group 3 in humans is unclassifiable, and Group 4 is probably not carcinogenic to humans. Only a little more than 100 are classified as Group 1 cancer-causing substances, including ultraviolet radiation and tobacco smoke.
“Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants,” the lARC's Dana Loomis said in a statement. “The results from the reviewed studies point in the same direction: the risk of developing lung cancer is significantly increased in people exposed to air pollution.”
In 2010, lung cancer resulting from air pollution killed 223,000 people worldwide, and there was also convincing evidence that it increases the risk of bladder (膀腕) cancer, according to the IARC.
Air pollution is already known to raise risks for a wide range of illnesses, including respiratory and heart diseases.
Air pollution is global, although the levels of it vary over space and time.
Loomis said people in Asia, eastern North America, some places in Central America and Mexico, as well as North Africa have relatively high exposure. Developing countries with large populations and booming manufacturing sectors, such as China, are particularly at risk.
Many cities in China, such as Beijing, frequently see smog. This week, Harbin, the capital city of Heilongjiang province, became the first Chinese city to officially suspend classes due to serious smog
Many developed countries face similar problems, although to a lesser degree than most developing nations. In Europe, levels of many pollutants have fallen. But between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5—tiny particles with a diameter of less than 2.5 micrometers—that are higher than the WHO safety limits, says a report published by the European Environment Agency on Oct 15.
Although both the composition and levels of air pollution can vary dramatically from one location to the other, the 1ARC said its conclusions apply to all regions of the world.
“Given the scale of the exposure affecting people worldwide, this report should send a strong signal to the international community to take action without further delay,” said Christopher Wild, director of the IARC.
【小題1】What might be the best title of the passage?
| A.Signals of air pollution |
| B.Safety limits of air pollution |
| C.Air pollution, cancer risk |
| D.Air pollution, smog risk |
| A.To focus on cancer-causing substances. |
| B.To evaluate the air quality. |
| C.To study the developing risk of cancer. |
| D.To send signals to the international community. |
| A.The composition and levels of air pollution vary from place to place. |
| B.More and more people in developing countries are exposed to air pollution. |
| C.Developed countries face air pollution, the level of which is higher than the safety limits. |
| D.A large number of people worldwide are exposed to air pollution. |

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.

All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.
Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for sleep mainly. TVs, computers and other things should not be in your bedroom if at all possible.
Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
Establish a pre-bedtime rule that will help you focus on sleep. You can try deep thought,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is best for you.
Things such as room temperature, noise and light levels and even your bed mattress(床墊) can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences.
【小題1】Which of the following is the best title for the text?
| A.How to Deal with Sleep Problems |
| B.What is the Process of Sleep |
| C.Where Should We Sleep |
| D.How to improve Sleep Quality |

Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people - up to 3 percent of the population - sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families - hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.
【小題1】What caused the happening mentioned in the passage during Amanda’s running?
| A.She couldn’t breathe in enough air in the race. |
| B.She didn’t eat anything before the race. |
| C.She had been running all summer without a rest. |
| D.She neither drank enough water nor ate enough of the right kind of foods. |
| A.There is no need to worry when sweating too much, even in cold weather. |
| B.Hyperhidrosis may have a bad effect on your health. |
| C.Doctors have discovered why people get hyperhidrosis. |
| D.Hyperhidrosis is a serious disease and no treatment can help. |
| A.tell teens the proper ways to take exercise in summer. |
| B.tell teens not to run in hot summer. |
| C.tell teens to pay attention to hyperhidrosis in the summer exercise |
| D.tell teens how to keep healthy. |

There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:
I’ll never lose weight --- I come from a fat family
Wrong! While we can’t change the body type we are born with, we can’t blame our genes for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.
I am fat because I burn calories slowly
Wrong! Fatness is not caused by a slow metabolism(新陳代謝). If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.
Exercise is boring
Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that’s fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.
No pain, no gain
Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don’t, rest and seek medical advice.
【小題1】What does the author think about being fat?
| A.It is the family genes that make people fat. |

| D.It is the consequence of people’s unbalanced lifestyle. |
| A.By taking varied exercise. |
| B.By choosing simple exercise. |
| C.By doing regular exercise. |
| D.By sticking to outdoor exercise. |
| A.Keeping fit is essentially a painful experience. |
| B.Exercise should be stopped if continuous pain is felt. |
| C.Pain in exercise is a precondition for reaching your goal. |
| D.Getting used to pain leads to positive changes in your body. |
| A.To declare the importance of keeping fit. |
| B.To clarify some misconceptions about fatness and exercise. |

Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化化學(xué)物質(zhì)) that may help stop the cell damage that can lead to disease.Researchers have been studying green tea’s effect on everything from cholesterol (膽固醇) to the risk of certain cancers,with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”,or problems with daily activities or basic needs,such as dressing or bathing.
Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled,compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older.Green tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more education,lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness.They also tended to be more socially active and have more friends and family to rely on.But even with those factors accounted for,green tea itself was tied to a tower disability risk,the researchers said.
People who drank at least five cups a day were onethird less likely to develop disabilities than those who had less than a cup per day.Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (緩沖) against disabilities,lead researcher Yasutake Tomata did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts,they do contain caffeine and small amounts of vitamin K,which means it could affect drugs that prevent blood clotting (凝固).
【小題1】What does the underlined word “peers” mean in the first paragraph?
| A.Fathers. |
| B.Brothers. |
| C.People of the same age. |
| D.People living in the same neighborhood. |
| A.Antioxidant chemicals can lead to disease. |
| B.Those who often drink green tea can’t develop “functional disability”. |
| C.“Functional disability” is related to problems with daily activities or basic needs. |
| D.People who drink at least five cups a day are not likely to become functionally disabled. |
| A.How the study was proved. |
| B.Why green tea lovers can keep agile. |
| C.What healthier diets include. |
| D.How to lower the disability risk. |
| A.Those who drank green tea can’t develop “functional disability”. |
| B.Green tea alone kept people agile as they grew older. |
| C.How green tea might offer a buffer against disabilities. |
| D.Green tea extracts seem to increase leg muscle strength in older women. |
| A.vitamin K is contained in caffeine |
| B.vitamin K is good for our blood |
| C.vitamin K is bad for our health |

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.
【小題1】What does the first paragraph mainly tell us?
| A.Something sportsmen should not do in practising yoga. |
| B.Basic skills that are required in performing yoga. |
| C.The performance of the sportsmen at the First World Yoga Championships. |
| D.The unique setting where yoga is performed. |
| A.To compare the differences between the young and the old. |
| B.To describe the extensive popularity of yoga in the US. |
| C.To emphasize the importance of practising yoga. |
| D.To explain the strong influence of public figures in the US. |
| A.It is a type of exercise which benefits the body and mind. |
| B.It makes muscles and joints stronger by stretching. |
| C.It contains exercise,breathing and meditation. |
| D.It is similar to the sports like football or running. |
| A.Women to be mothers. | B.Teenagers under 16. |
| C.Adult men. | D.Children with autism. |
