Below is some advice on how to prevent cancer:
8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon(结肠) cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate(石榴)Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.
3. Relax
Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of stressing about the past or future, focus on the present and relax!
4. Take Selenium(硒)
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate(前列腺) cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi(寿司)
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp(节省)on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
There’s no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen(致癌物质) in their urine(尿) than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a percent lower risk of metastasis(转移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.

Children of America are getting fatter every time. 13% of the children at the age of 6 to 11 are overweight(too fat).
When we look at children"s lives today in the USA, we can see the root(origin)of the problem--sports and foods. Young children like sports but they don"t have enough around the start of high school. That"s especially true for girls. Meanwhile, to make matters worse, schools are becoming much more interested in sports teams. So children are not able to get enough exercise just when they need it the most. There is also the food problem. Children get most of their calories(热量) at restaurants or parties or somewhere else away from home. They often drink too many Cokes. Parents have a lot of fears about telling a child he needs to lose weight-- they are afraid it will push a child into an eating disorder. Some parents fear that pushing children to lose weight means their children will think they"re not good enough, or not loved because of their weight. Parents need to come to terms with the fact that the family is very important to the children. The most useful program for children is called "family weight control". This is good news. Mom and Dad, even if they don"t have weight problems, have to go through the same program as their children and learn how to get some exercise and how to eat healthily.

How to Be a Winner
Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
“In 1997 I was found to have developed diabetes (糖尿病) . Believing my career (职业生涯)was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it----the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn’t finished yet. Nothing is to stand in my way.”
Karen Pickering
Swimming World Champion
“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success—you can’t follow a career in any field without being well-organized. List what you believe you can achieve. “Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”
Kirsten Best
Poet & Writer
“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological (心理的) tool.”

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine,newspaper,radio and television ads,promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs,slim the face,smooth wrinkles,or in some other way to add to beauty or desirability.
Often such products are nothing more than money­making things for their promoters. The results they produce are questionable,and some are dangerous to health.
To understand how these products can be legally promoted to the public,it is necessary to understand something of the laws covering their regulation. If the product is a drug,FDA(Food and Drug Administration)can require proof under the Food,Drug,and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device,FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health,FDA can request the producer or distributor to remove it from the market voluntarily,or it can take legal action,including seizure(查封)of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor,which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously,most of the devices on the market have never been the subject of court proceedings(法律诉讼),and new devices appear continually. Before buying,it is up to the consumer to judge the safety or effectiveness of such items.
小题1:It can be inferred that the ads mentioned in the text are________.
A.objectiveB.costlyC.unreliableD.illegal
小题2:FDA can ask for the proof of safety and effectiveness of a product ________.
A.if it is a drug
B.if it is a device
C.if its consumers make complaints
D.if its distributors challenge FDA"s authority
小题3:The Relaxacisor is mentioned as________.
A.a product which was designed to produce electricity
B.a product whose distributor was involved in a legal case
C.a successful advertisement of a beauty product
D.an example of a quality beauty product
小题4:The author intends to________.
A.make consumers aware of the promoters" false promises
B.show the weakness of the law on product safety
C.give advice on how to keep young and beautiful
D.introduce the organization of FDA

There is one type of illness in the world that affects more people than anything else and is very deadly. If untreated this illness could affect everything you do. What is this illness? Depression. Serious depression requires professional treatment. Self-induced depression is something each of us can change.
Everyone"s circumstances are different, but the causes of self-induced depression are common: low self-esteem, hurtful thinking and a bad attitude.
So how can we change the way we think, feel, and cultivate a cheerful attitude?
First we must look at ourselves, truly and honestly examining our motives for what we wish to achieve. If you are dissatisfied because you feel you haven"t or can"t do anything, then one step is needed - to set goals.
Always start your goals relatively small and easy to attain. Think of them as sand; one grain may be insignificant but as a group they form the beach. Once you have set and attained small goals for yourself, move on to slightly larger, more challenging goals.
It takes more than just setting goals to be happy. It takes positive thinking. How can we attain this?
There are a number of factors that can make us think negatively and one of those is diet.
In my opinion, a person who eats a lot of take out and fast food is feeding their body junk. Start by eating better foods which give the body much NEEDED minerals. If your physical body is happy, it"s much easier for your mental body or "thinking ability" to be happy.
Next, exercise. A half-hour a day is recommended for positive well being. Then think about good memories you had, or generally think of things that make you smile. Remember, everything you wear costs money but to wear a smile is free. A smile can be the difference between an average day and a great day.
If you follow these steps, positive change is inevitable.
小题1:Which of the statements about depression is TRUE?
A.Depression is a kind of illness that can’t be cured like some cancer.
B.Depression can all be cured successfully by patients themselves.
C.Those who suffer from depression feel dissatisfied with themselves.
D.Those who suffer from depression live in similar circumstances.
小题2:According to the passage we can learn that ____________.
A.a practical goal can help people to achieve a sense of success
B.we shouldn’t be satisfied with small goals that are insignificant
C.we should avoid challenging goals that may lead to failure
D.people can enjoy happiness only if they set reasonable goals
小题3:In order to achieve positive thinking a person should do these things EXCEPT____________.
A.set challenging goalsB.eat healthier foods
C.exercise half an hour a dayD.always wear a smile
小题4:What’s the passage mainly about?
A.To prove the argument that depression can be changed.
B.To analyze the danger depression can bring to people.
C.To introduce to readers how to keep positive thinking.
D.To recommend some ways to deal with depression.
