Risk of death is 3.5 to 5 times greater for obese (肥胖的) smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.www.zxxk.com
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (斷奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans，”said study researcher McMahon. “If the mechanism (機制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”
【小題1】How many groups of mice are there finally in all in the experiment?
| A．Four. | B．Five. | C．Six. | D．Seven. |
| A．The biological clock regulates mood in humans. |
| B．People born in winter are at higher risk for physical health disorders. |
| C．Being born in winter has a negative effect on people's mental health. |
| D．The length of light will influence the behavior of the mice. |

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. |
| 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 |
| A．interesting | B．strange | C．significant | D．a(chǎn)mazing |
| 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 |
| A．eating a good lunch | B．doing puzzles |
| C．eating a large supper | D．taking aerobic exercise |

If a city wishes to host the Olympics, it must submit a proposal(提交提案) to the IOC. After all proposals have been submitted, the IOC votes. If no city with the fewest votes is eliminated, the voting continues, until a majority winner is determined. Typically the Games are awarded several years in advance, allowing the winning city time to prepare for the Games.
In selecting the site of the Olympic Games, the IOC considers a number of factors, and chiefly among them is which organizing committee seems most likely to stage the Games effectively. The IOC also considers which parts of the world have not yet hosted the Games. For instance, Tokyo, the host of the 1964 Summer Games, and Beijing, that of the 2008 Games, were chosen in part to popularize the Olympic movement in Asia. Because of growing importance television worldwide, the IOC in recent years has also taken into account the host city’s time zone. Whenever the Games take place in the USA or Canada, for example, American television networks are willing to pay specially higher amounts for television rights because they can broadcast popular events live in the best viewing hours.
Once the Games have been awarded, it is the duty of the local organizing committee----not the IOC or the NOC of the host city’s country to provide them with money. This is often done with a part of the Olympic television revenues(收入), and corporate sponsorships(社團贊助), tickets sales, and other smaller revenue sources. In many cases there is also direct government support. Although many cities have achieved amounts of money by hosting the Games, the Olympics can be financially risky. When the financial gains from the Games were less than expected, the city was left with large debts.
【小題1】_______will be determined to host the Olympic Games by the IOC.
A. A city that submits a proposal B. A majority winner in voting
C. A city that has perfect time zone D. One that hasn’t hosted the Games
【小題2】 Which of the following words can be used to replace the word “ selecting” in paragraph 2?
| A．electing | B．hoping | C．choosing | D．thinking |
| A．can’t broadcast popular events live in the best viewing hours |
| B．will be forbidden to broadcast live sporting events |
| C．a(chǎn)re willing to pay much higher amounts for television rights |
| D．will not pay for the Canadian television networks |
| A．The host city must be left with large debts |
| B．The city may achieve a lot of money |
| C．There is no financial risk in hosting the Olympic Games |
| D．It is impossible that the host city couldn’t make money |
| A．How to host Olympic Games | B．Winner or loser |
| C．Applying for host for Olympics | D．The Olympic Games |

If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks (口罩) trying their best to stop the swine flu (豬流感). And the masks aren’t only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask!
But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC’s reporter Sharyn Alfonsi talked with germ (細菌) expert Dr. Elaine Larsen. It turns out that when you sneeze (打噴嚏) the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected (被感染).
However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won’t become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else’s nose, mouth or their mask.
Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often.
【小題1】According to Para.1, in Mexico you can see that ____.
| A．the patients are treated in the open air |
| B．some doctors work in the street |
| C．people speak little to each other in the street |
| D．many people wear masks in the street |
| A．breathing | B．Speaking | C．touching others | D．sneezing |
| A．sick people will be infected |
| B．germs can spread very far |
| C．germs spread very quickly |
| D．few people will be infected |
| A．the mask will be old and worn out |
| B．you’ll love the feeling of wearing it |
| C．germs will be kept away from you |
| D．it will be easy for you to be infected |
| A．Keeping the masks dry. | B．Changing the masks often. |
| C．Choosing very thick masks. | D．Wearing big masks. |

Are you having too much salt? You might not think so, but people in China eat on average (平均) about 12 grams of salt each day, that is much higher than the 6 grams suggested by the World Health Organization. You could be eating too much without realizing it, because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages.
What problems can eating too much salt cause? To answer that question, first let’s take a look at what salt is.
Salt is a chemical compound. It is made of sodium (鈉) and chloride (氯化物). Salt is used to keep and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride to work.
But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been connected with other conditions, such as heart and kidney (腎) problems.
If you want to cut down on salt, the good news is, there are plenty of simple things to do. Here are some tips:
*Cut back on high salt foods.
Most foods contain some salt. But some foods such as cheese, bacon, pickles (泡菜), smoked fish and chips are almost always high in salt because of the way they are made. You can still enjoy them, but try to have these in smaller amounts, or eat them less often.
*Choose reduced salt bread and breakfast cereals.
Bread and breakfast cereals (谷物) are major source of salt in the diet, not that they’re necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you’re shopping, take the time to compare the salt levels on a few similar products. And always try to choose the ones lower in salt.
*Avoid adding salt to cooking and at table. Instead, you could use herbs and spices (香料) such as garlic (大蒜) and lemon juice to add flavor to meals.
【小題1】Many people in China don’t realize they are eating too much salt because ______.
| A．salty food tasted better than reduced salt food |
| B．they do not calculate the amount of salt they eat |
| C．a(chǎn)bout 3/4 of the salt we eat is already in the food we buy |
| D．few people experience problems from eating too much salt |
| A．cut back on food with less salt |
| B．eat less heavily salted food |
| C．eat as much reduced salt bread as is wanted |
| D．stop eating bread and breakfast cereals |
| A．To warn people of food containing too much salt. |
| B．To inform people of the right amount of salt taken each day. |
| C．To advise people to be careful about the amount of salt they eat. |
| D．To promote (促進) the right way to make reduced salt food. |

Try physical activity
When you are nervous, angry or upset, try reducing the pressure through exercise of physical activity. Running, walking, playing tennis or working in your garden are just some of the activities you might try. Physical exercise will relieve your anxiety and worry and help you to relax. Your body and your mind will work together to ease the stress in your life.
Share your stress
It helps to talk to someone about your anxiety and worries. Perhaps a friend, family member, teacher or even your leader can help you a better view of what is troubling you.

Schedule time for both work and entertainment. Don’t forget, play can be just as important to your over-all well-being as work. You need a break from your daily routine to just relax and have fun. Go window-shopping or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.
Make a list of things you need to do
Stress can result from disorganization and a feeling that “there is so much to do, and not enough time.” Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything.

Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
【小題1】What is the best possible title of the passage?
| A．Drug and Food | B．Food and Health |
| C．Cancer and Health | D．Health and Drug |
| A．Some of the additives in our food are added to the food itself and some are given to the living animals |
| B．Researchers have known about the potential dangers of food additives for about sixty-eight years. |
| C．Drugs are always given to animals for medical reasons |
| D．Food may cause forty percent of cancer in world. |
| A．Because of science, diseases caused by polluted food have been virtually eliminated. |
| B．It has caused a lack of information concerning the value of food. |
| C．The scientists have preserved the color of meats, but not of vegetables. |
| D．Because of the application of science, some potentially harmful substances have been added to food. |
| A．They preserve the color of meats. |
| B．They preserve flavor in packaged foods. |
| C．They are the objects of research |
| D．They cause the animals to become fatter. |
| A．trouble-making | B．color-retaining |

Honey from the African forest is not only a kind of natural sugar, it is also delicious.
Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper - a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
【小題1】Why is it difficult to find a wild bees' nest?
| A．It's small in size. | B．It's hidden in trees. |
| C．It's covered with wax. | D．It's hard to recognize. |
| A．A bee. | B．A bird. |
| C．A honey seeker. | D．A beekeeper. |
| A．it gets its food | B．it goes to church |
| C．it sings in the forest | D．it reaches into bees' nests |
| A．Wild Bees | B．Wax and Honey |
| C．Beekeeping in Africa | D．Honey-Lover's Helper |
