Do junk food ads make kids fat? Should they be banned? Based on the evidence, more and more experts say yes. The latest support comes from a group of New Zealand experts who say they've made a link between kids watching television and bad health.
Researchers from the University of Otago in Dunedin studied 1000 children from age 3 to 26．They found that those who watched television more than two hours a day had higher levels of obesity（肥胖）, blood cholesterol（胆固醇）and smoking — as well as lower levels of physical fitness — when they reached adulthood than kids who watched less than two hours a day.  
Why? Partly because while they are watching TV kids aren't getting out, exercising and playing with other kids, and burning off the calories. But more insidiously（不知不觉地）, while watching TV, they're being shown a lot of ads for drinks and foods of uncertain nutritional value, most of which are full of sugar and fat.
Across the globe, about 155 million kids are obese, according to the International Obesity Task Force. The dangerous thing is not just the well-being of these kids as they grow up, but hundreds of billions of dollars of health costs spent on adults with heart disease, diabetes（糖尿病）, and the disabilities these disease will cause.
In Australia, two thirds of children are overweight and one third are obese. Twenty years ago, only about ten per cent were obese. And Australia has the greatest amount of junk food ads per hour of television than any other country in the world, including the US and the UK. About 30 per cent of all ads in kids' viewing time are for food or drinks. Most of them are for junk food: burgers, chips, soft drinks and sweets —high in fat, salt or sugar.
Here in Australia, experts are also calling for a ban on TV advertising of junk food to kids. The Coalition on Food Advertising to Children （CFAC） wants to make changes to laws, hoping it can ban all food advertising on TV during the time of the day when children under 12 years old are watching. This includes early and afternoon time, and evening TV between 5 pm and 9 pm.

A healthy dose of sunshine may be the secret to staying young, British scientists have disclosed.
Vitamin D is produced naturally by the skin in response to sunlight and may help to slow the ageing process and protect against heart disease, according to the study.
Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres - a biological marker of ageing found in DNA．As people get older, their telomeres get shorter and they are easy to have illnesses.
But the study found women with high levels of vitamin D had comparatively longer telomeres - a sign of being biologically younger and healthier.
The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.
Lead researcher Dr Brent Richards said: "These results are exciting because they prove for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D．
"This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."
He said further studies are required to confirm the findings.
Professor Tim Spector, head of KCL's twin research unit, and a co-author of the report, added: "Although it might sound absurd(荒谬的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process."
Vitamin D made by the action of sunlight on the skin accounts for 90 per cent of the body's supply, but lower levels can also be obtained through food such as fish, eggs and breakfast cereals.
Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.

Over the last 70 years,researchers have been studying happy and unhappy people and finally found out ten factors that make a difference.Our feelings of well-being at any moment are determined to a certain degree by genes.However,of all the factors,wealth and age are the top two.
Money can buy a degree of happiness.But once you can afford to feed,clothe and house yourself,each extra dollar makes less and less difference.
Researchers find that,on average,wealthier people are happier.But the link between money and happiness is complex.In the past half-century,average income has sharply increased in developed countries,yet happiness levels have remained almost the same.Once your basic needs are met,money only seems to increase happiness if you have more than your friends,neighbors and colleagues.
“Dollars buy status,and status makes people feel better,”conclude some experts,which helps explain why people who can seek status in other ways—scientists or actors,for example—may happily accept relatively poorly-paid jobs.
In a research,Professor Alex Michalos found that the people whose desires—not just for money,but for friends,family,job,health—rose furthest beyond what they already had,tended to be less happy than those who felt a smaller gap(差距).Indeed,the size of the gap predicted happiness about five times better than income alone.“The gap measures just blow away the only measures of income,”says Michalos.
Another factor that has to do with happiness is age.Old age may not be so bad.“Given all the problems of aging,how could the elderly be more satisfied?”asks Professor Laura Carstensen.
In one survey,Carstensen interviewed 184 people between the ages of 18 and 94,and asked them to fill out an emotions questionaire.She found that old people reported positive emotions just as often as young people,but negative emotions much less often.
Why are old people happier?Some scientists suggest older people may expect life to be harder and learn to live with it,or they’re more realistic about their goals,only setting ones that they know they can achieve.But Carstensen thinks that with time running out,older people have learned to focus on things that make them happy and let go of those that don’t.
“People realize not only what they have,but also that what they have cannot last forever,”she says.“A goodbye kiss to a husband or wife at the age of 85,for example,may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20.”
小题1:According to the passage,the feeling of happiness______.
A．is determined partly by genes
B．increases gradually with age
C．has little to do with wealth
D．is measured by desires
小题2:Some actors would like to accept poorly-paid jobs because the jobs______.
A．make them feel much better
B．provide chances to make friends
C．improve their social position
D．satisfy their professional interests
小题3:Aged people are more likely to feel happy because they are more______.
A．optimistic
B．successful
C．practical
D．emotional
小题4:Professor Alex Michalos found that people feel less happy if______.
A．the gap between reality and desire is bigger
B．they have a stronger desire for friendship
C．their income is below their expectation
D．the hope for good health is greater
Parents who smoke often open a window or turn on a fan to clear the air for their children, but experts now have identified a related threat to children's health that isn't as easy to get rid of: third-hand smoke。
That's the term being   1  to describe the invisible yet poisonous mixture of gases and particles(颗粒) clinging(依附) to smokers' hair and   2 , not to mention cushions and carpeting, that stays long after second-hand smoke has cleared from a room. The remaining   3 heavy metals, carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in,   4 if they're crawling or playing on the floor。
Doctors from MassGeneral Hospital for Children in Boston coined the term "third-hand smoke" to   5 these chemicals in a new study that   6 on the risks they pose to infants and children. The study was published in the  7 issue of the journal Pediatrics。
"Everyone knows that second-hand smoke is bad, 8 they don't know about this," said Dr. Jonathan P. Winickoff, the lead author of the study and an assistant professor of pediatrics at Harvard Medical School。
"When their kids are   9 the house, they might smoke. Or they smoke in the car. Or they strap(用带子捆扎) the kid in the car seat in the back and crack the window and   10 , and they think it's okay because the second-hand smoke isn't getting to their  11 . We needed a term to describe these tobacco toxins that aren't  12 ."
The study reported on  13 toward smoking in 1,500 households across the United States. It found that the vast majority of both smokers and nonsmokers were   14 that second-hand smoke is harmful to children. Some 95 percent of nonsmokers and 84 percent of smokers  15 with the statement that "inhaling smoke from a parent's cigarette can   16 the health of infants and children"。
But   17 fewer of those surveyed were aware of the  18 of third-hand smoke. Since the term is so new, the researchers asked people if they agreed with the statement that "breathing air in a room   19 where people smoked yesterday can harm the health of infants and children"。
Only 65 percent of nonsmokers and 43 percent of smokers agreed with that  20 , which researchers interpreted as acknowledgement of the risks of third-hand smoke。

Healthy knees aren’t the main consideration in choosing high heels,but new research says chunky heels are just as bad for the knees as spindly stilettos（细高跟鞋）.“It takes a long time to feel the effects of knee osteoarthritis（骨关节炎）—and once you do it,it is too late,”said Dr.Casey Kerrigan,leading researcher of the study and associate professor at Harvard Medical School’s department of physical medicine.“I compare it to smoking—one cigarette is not painful,but over a lifetime it is.Wide-heeled shoes feel comfortable,so women wear them all day long,”Kerrigan said.“They are better for your feet than stiletto heels,but just as bad for your knees.”
In the study,researchers had twenty women wear two pairs of shoes with three-inch heels,one with a narrow heel and the other with a thick one.The scientists compared how much pressure was put on the women’s knees by both types of shoes.The women also walked bare-foot to test normal pressure.The scientists found that both types of shoes applied equal amounts of pressure to the knees.Compared with walking barefoot,the heels increased pressure on the inside of the knee by 26 percent.Increased pressure on the knee eventually leads to arthritis,experts say.
The idea that high heels are bad for your health isn’t new—scientists have warned women for years that they contribute to problems ranging from corns to hammer toes,tendonitis,knee pain,sprained(扭伤)ankles and back problems.But in 1998,Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis,a painful joint disease that destroys cartilage(软骨)surrounding the knee.The first study looked only at stiletto heels,and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.“This study confirms what we all intuitively（直觉地）know that high-heeled shoes of any kind are not good for our health,”said Dr.Glem Pfeffer,a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.

Vitamin E supplements(补充品)，which millions take in the hope of longer, healthier lives, may do more harm than good, researchers reported on Wednesday.?
In fact, people taking high doses(剂量)of vitamin E may in some cases be more likely to die earlier, although the reasons are not clear, said Dr. Edgar Miller of Johns Hopkins University in Baltimore, who led the study.“I think people take vitamin E because they think it is going to make you live longer, but this(study)doesn’t support that.”Miller told reporters.?
Miller and colleagues re?analyzed 19 studies of vitamin E and health between 1993 and 2004. The tests involved more than 136,000 mostly elderly patients in North America, Europe and China. People who took 200 international units of vitamin E a day or more died at a higher rate during the study, which lasted three years, than people who did not take supplements, they told a meeting of the American Heart Association.“It’s about a 5 percent increased risk at 45 years in the tests combined together，”Miller said.“That doesn’t sound like a lot but if you apply it to 25 percent of the (U.S.)adult population taking vitamin E, that is significant.”?
Miller, whose findings are also being published online by the Annals of Internal Medicine, said two?thirds of people who take vitamin E supplements take 400 IU or more.“We don’t think that people need to take vitamin E supplements, which they can get enough from the diet,”he said. Nuts, oils, whole grains and green leafy vegetables are all rich in vitamin E.?
小题1: People take vitamin E supplements, hoping that________.?
A．they can lose weight easily?
B．they may live a longer and healthier life?
C．they can get more and more beautiful?

A．Miller and his team based their research on 19 cases of vitamin E and health between 1993 and 2004?
B．Miller thinks it unnecessary for people to take vitamin E supplements?
C．Miller supposes it impossible for people to get enough vitamin E from their diets?
D．Miller played an important role in the tests conducted by the researchers
小题3:  Which of the following contains rich vitamin E??
A．Nuts.
B．Whole grains.?
C．Green leafy vegetables.
D．All of the above.
小题4: What is this text mainly about??
A．It is reported in a study that vitamin E may do more harm than good to people to live longer and get healthier.
B．Dr.Edgar Miller and his colleagues studied many cases of vitamin E and health.?
C．Dr.Edgar Miller advises that people should not depend on vitamin E supplements for longer and healthier lives.
D．People who took 200 international units of vitamin E a day or more died at a higher rate than people who did not take supplements.
Do you wake up in the morning dreading the moment that your feet have to hit the floor for you to get ready for work? If that’s the case, join most of Americans. Very few people wake up to that annoying alarm clock and spring out of bed excited about having to go to work.
As if that were not enough, most of us have to fight traffic getting there, usually an hour’s drive. Then, when we get to work, we have to fight with unruly co-workers or a nagging boss. And to make matters worse, you have to fight the same traffic going in the opposite direction just to get back home.
Making dinner, fixing plates, eating and then straightening up afterwards is a job within itself. If that sounds like your life, you probably have a J-O-B. you know what J-O-B stands for? Just Over Broke, that’s what! With a job, most Americans are living paycheck-to-paycheck and hating every minute of it. I know because I was doing the same thing: trading time for money. And, I came to a conclusion that it stinks (糟糕透了)! Big time!
Looking around at my co-workers, friends and relatives, I saw that they were all doing the same thing I was doing. They were complaining about the same things I was complaining about : not having enough time or money. And, I decided that I wanted to do something different.
So, I started a home-based business. There are several to choose from. The extra income has done so much for our family. We can vacation more. We have been able to give more. And, we’ve even been able to do something calling save! It’s been amazing.
Therefore, if you’re sick and tired of being sick and tired, it’s time you make a change, too. The definition of insanity (疯狂) is doing the same thing over and over and expecting different results. I know you aren’t stupid. If you continue to do what everyone else is doing: trading time for money, you’re going to keep getting what everyone else is getting: being broke and not having the time to do what is really important to you.
Do your due diligence. Find a home-based business that works well for you. Go to work, and live the life you’ve always imagined!
小题1:According to Paragraph 1, which of the following statements is TRUE about most Americans?
A．Most Americans are excited to go to work every day.
B．Most Americans are used to sleeping in the morning.
C．Most Americans are tired of having to go to work every morning.
D．Most Americans have alarm clocks to wake them up in the morning.
小题2:By writing the first three paragraphs, what feeling does the writer express?
A．Regret.B．Joy.C．Pride.D．Dissatisfaction
小题3:What does “something different” in Paragraph 4 refer to?
A．To set up a business at home.B．To complain about life and work.
C．To spend more time on holidays.D．To resign from the former job and get a new one.

B
As a kid, I can remember going to the supermarket and grabbing eggs off the shelf. I would run them home to my mother because they were usually going into a delicious cake. Times have changed. Cage-free? Organic? Brown? White? Omega-3s(一种脂肪酸)?Help! Here are some tips to help you figure out which eggs you should be eating.
Brown or white? In fact, color is simply a sign of the breed of hen. Find the freshest egg with the most flavor and let color be a secondary concern.
Extra Omega-3s? Omega-3 eggs come from a hen whose diet has added flaxseed (亚麻籽)，which produces an egg containing an average of 225 mg of Omega-3 fatty acids and vitamin E. The countless health benefits for humans make these eggs an attractive purchase. My opinion? Eat a piece of fresh fish and get a pure pill of Omega-3s. Let eggs be eggs.
Does your egg need exercise? Free-range eggs are from hens raised without the limit of a cage, though they may or may not have spent much time outdoors. Organic eggs are from hens whose food must meet organic standards. These hens must be raised humanly, and they must be given time to the outdoors. Hey, happier hens do lay tastier eggs.
Does local make a difference? Nothing is better than local eggs. They may have a feather or two stuck to them or be a little imperfect in shape and may or may not be certified organic; however, they have one quality. I know exactly where my food came from and how it came into being! In some cases I can even ask the farmer when the eggs were laid and what they were fed.
55.What’s the best title for this passage?
A．Which Eggs Should You Be Eating?       B．Eggs Are Changing as Times Are Changing
C．Which Kind of Egg Is the Best?           D. The First Concern When Choosing Eggs
56. What does the author think of extra Omega-3s eggs?
A．They are a good choice for people to buy.   
B．They contain fewer Omega-3s than fresh fish.
C．They have the highest content of pure Omega-3s.
D．They are not the best source of Omega-3s.
57. The underlined word “free-range” probably means “________ ”
A．wild        B．cage-free         C．organic        D．Omega-3-free
58.According to the passage, which of the following has nothing to do with an egg’s quality?
A．The egg’s color.                         B．The hen’s exercise.  
C．The hen’s living conditions.                D．The hen’s food.
