A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma(黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence(發(fā)生率)faster than any other cancer in the United States.
But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles(雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
【小題1】The underlined word “flaws” in the 2nd paragraph most probably means       .

A.evidences B.facts C.faults D.failures
【小題2】People with fair skin and freckles         .
A.seldom use sunscreen
B.a(chǎn)re more in danger of skin cancer
C.can be free from the harm of the sun
D.often expose themselves to the sun
【小題3】We can learn from the passage that         .
A.sunscreen users get skin cancer more often
B.the volunteers have proved the effect of sunscreen
C.the new study was based on the experiences of volunteers
D.the number of skin cancer patients is increasing in America
【小題4】Which of the following can be the best title for this passage?
A.Sunscreen to Prevent Skin Cancer

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊貓)eats only one particular type of bamboo(竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶)will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet(多樣化飲食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
【小題1】We can infer from the text that humans and animals _________.

A.depend on one sense in choosing food
B.a(chǎn)re not satisfied with their food
C.choose food in similar ways
D.eat entirely different food
【小題2】Which of the following eats only one type of food?
A.The white butterfly. B.The small bird.
C.The bear. D.The fox.
【小題3】Certain animals change their choice of food when ___________.
A.the season changes
B.the food color changes
C.they move to different places
D.they are attracted by different smells
【小題4】We can learn from the last paragraph that __________.
A.food is chosen for a good reason
B.French and British food is good
C.some people have few choices of food
D.some people care little about healthy diet

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(guò)多的) calories.

Cell phones:  is there a cancer link?
Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病學(xué)) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ” said Linet. “We don’t have the evidence that there’s much danger. ”
Studies so far suggest a weak connection between EMFs(電磁場(chǎng)) and illness— so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.
【小題1】From the passage we can learn that some people are worried because _______.

A.they have evidence that the use of cell phones can lead to cancer
B.they make a fuss over cell phone use
C.some experts have given a warning
D.cell phones are responsible for brain tumors
【小題2】By saying “I don’t support warning labels for cell phones, ” Dr Martha Linet has the idea that _______.
A.the worrying is unnecessary
B.cancer-warning labels should be on cell phones
C.there is a link between cell phones and cancer
D.cell phones have nothing to do with cancer
【小題3】Which of the following best describes the attitude of the author towards the debate?
A.Optimistic. B.Objective.
C.Opposite. D.Casual. ]

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.
【小題1】According to the report         is the disease most difficult to fight.

A.malaria B.tuberculosis C.AIDS D.influenza
【小題2】To prevent these diseases, a large amount of money is needed to          .
A.to buy food and pay for the caretakers
B.do research work, buy drugs and devices
C.take care of the families of the deaths
D.set up more hospitals and health institutions
【小題3】We can infer from the text that reducing infectious diseases is          .
A.to help the countries develop better
B.to promote cooperation between countries
C.to help people get more scientific knowledge
D.to help people get a cleaner environment
【小題4】Most serious infectious diseases spread mainly in         .
A.Africa B.South America
C.Asia D.developing countries
【小題5】To fight the diseases,         is necessary.
A.better environment
B.cooperation between different people

Are you stressed out, scared or worried all the time? Do you avoid going to certain places, seeing friends or doing certain things because of your worries? Do your worries keep you awake at night? If you’ve answered yes, you may be suffering from anxiety.
Anxiety is a normal and necessary part of life. Anxiety is your brain’s way of telling you about danger. It is anxiety which helps you jump out of the way if a car is speeding towards you. But if it gets out of hand, anxiety can get in the way of your getting on with life and can become a real problem. If this is the case for you, treatment may be a helpful way for you to get your anxiety under control.
Anxiety is a normal part of life. Some people may feel uneasy if moving to a new place and some may get overly anxious in certain situations. There are lots of reasons for this. One main reason is after a stressful thing which has happened in your life. So, if you are involved in a car crash, it’s quite likely that you will be more worried than other people around cars and driving.
Being anxious also probably runs in families. If your parents suffer from anxiety then you are more likely to be anxious too. This is probably partly due to genetics, and partly because of how things are when you’re growing up.
Even though people don’t talk about it much, anxiety is one of the most common mental health problems. About 1 in 4 people will have an anxiety problem at some time in their life.
If you have an anxiety problem it’s hard for other people to understand why something that doesn’t worry them, like being in a crowd of people, can be so scary for you. This can make you feel separated and lonely, as may become worse and worse.
The good news is there are lots of excellent treatments available for anxiety. These include taking therapies (療法) and drugs.
【小題1】Which of the following statements is true about anxiety?

A.With anxiety you are far away from traffic accidents.
B.It’s abnormal for people to get too anxious after a stressful thing.

Below are some smart ways to stay healthy suggested by some American experts.

Drink More Coffee
When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”
Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.
“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”
Take a Walk for Your Memory
Aerobic (有氧運(yùn)動(dòng)的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (腦衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.
It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”
Early to Bed, Early to Eat
“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.
“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”
Use the 20-Second Rule
What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.
Imagine the Worst to Feel Better
Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.
【小題1】 According to Sanjiv Chopra, most people should not drink more than ______ cups of coffee a day.
A.twoB.threeC.fourD.six
【小題2】Which of the following may help people on a diet to improve their results?
A.Raising their heart rate.B.Taking a walk for their memory.
C.Eating at fixed times.D.Sleeping in every morning.
【小題3】According to Shawn Achor, if people place their shoes and exercise clothes next to their bed at bedtime, they’re more likely to ______ the next morning.
A.do exerciseB.set a goal
C.cut 20 seconds offD.sleep 20 minutes more
【小題4】 Why should people spend a little time imagining their life without good things?
A.To experience surprise.B.To feel better.
C.To consider their own blessings.D.To prepare for the worst.

New rules will let millions of Americans know where more of their food comes from. The law is known as COOL -- Country of Origin Labeling(標(biāo)簽).
American congress first passed the law in 2002. Stores have had to label seafood by country of origin since 2005. But industry pressure delayed other requirements until last week.
Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts. But the rules are complex, and many foods are not included. For example, organ meats are free to be labeled. So are processed foods, including cooked or smoked foods.
The same food may sometimes have to be labeled and other times not. Fresh or frozen peas, for example, have to be labeled but not canned peas. Foods that are mixed with other foods are also excluded. Mixed nuts, for example, do not need to be labeled. The same is true of a salad mix that contains different things like lettuce and carrots. Or a fruit cup that combines different fruits. Also, the law doesn’t include restaurants and other food service organizations. Department of Agriculture officials say the law is really meant for larger grocery stores.
The United States has imported more and more food in recent years to save money and expand choices. Country-of-origin labeling has become more common lately but has still been limited in many stores.
Food safety is one reason why some shoppers pay close attention to where foods came from. For example, when a large number of people recently got sick from salmonella(沙門(mén)菌病), officials blamed peppers from Mexico. Yet the last big food scare involved spinach grown in California. But labeling is also a way for people to know they are getting what they want. Some want to buy local foods or foods from a particular country.
The country-of-origin labeling law gives stores 30 days to correct any violations(違反) that are found. Stores and suppliers that are found to be deliberately violating the law could be fined 1,000 dollars per violation. Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.
Some food safety activists say they are generally pleased with the law. They call it a good step that will give people more useful information.
【小題1】Why has more and more food been imported to the United States in recent years?

A.It is economical and provides people with more choices.
B.Foreign food is of higher quality than native food.
C.Americans need more and more food recently.
D.The United States is short of food supply.
【小題2】Consumers are more concerned about where foods come from because________.
A.they are curious about the origin of the food.
B.most of them are particular about the tastes
C.they are concerned about food safety
D.most of them are food safety activists
【小題3】The new rules of the country-of-origin labeling law will come into effect________.
A.right now B.in a month C.in three months D.in half a year
【小題4】Which of the following can be inferred from the text?
A.Store owners are most likely to be the supporters of the law.
B.The government of America will possibly forbid importing peppers from Mexico.
C.Federal inspectors couldn’t take measures to enforce the law.
D.Most Americans prefer imported vegetables to the vegetables grown in local places.
