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.

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple.
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP section and pays for the bill with the wave of an arm.
Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits.
When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
The article is intended to .

A.warn people of the possible risks in adopting RFID technology
B.explain the benefits brought about by RFID technology
C.convince people of the uses of RFID technology
D.predict the applications of RFID technology

We know from the passage that with the help of RFID tags, people .

A.will have no trouble getting data about others
B.will have more energy for conversation
C.will have more time to make friends
D.won’t feel shy at parties any longer

Passive RFID tags chiefly consist of .

A.scanning devices B.radio waves C.batteries D.chips

Why are some people worried about RFID technology?

A.Because children will be tracked by strangers.
B.Because market competition will become more fierce.
C.Because their private lives will be greatly affected.
D.Because customers will be forced to buy more products.

The last paragraph implies that RFID technology .

A.will not be used for such matters as buying milk
B.will be widely used, including for buying milk
C.will be limited to communication uses
D.will probably be used for pop music

When I met him, I had a lot of anger inside of me. I’ve lived my whole life in Spanish Harlem, but in my neighborhood, there are shoot-ups all the time. I know kids who have been shot or beaten up. I have friends who ended up in prison. I could have ended up that way, too, but Mr. Clark wouldn’t let that happen.
Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact, the scores of our whole class rose. One day, he took our class to see The Phantom of the Opera, and it was the first time some kids had ever been out of Harlem. Before the show, he treated us to dinner at a restaurant and taught us not to talk with our mouths full. We did not want to let him down.
Mr. Clark was selected as Disney’s 2000 Teacher of the Year. He said he would draw three names out of a hat; those students would go with him to Los Angeles to get the award. But when the time came to draw names, Mr. Clark said, “You’re all going.”
On graduation day, there were a lot of tears. We didn’t want his class to end. In 2001, he moved to Atlanta, but he always kept in touch. He started giving lectures about education, and wrote a bestselling book based on his classroom rules, The Essential 55. In 2003,
Mr. Clark took some of us on a trip to South Africa to deliver school supplies and visit the orphanages (孤儿院). It was the most amazing experience of my life. It’s now my dream to one day start a group of women’s clubs, helping people from all backgrounds.

Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat, when a manager gets a new sports car, a big house and pleasure boats dance into view.
The many needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears.
The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War Ⅱ, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses.
By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared; the “life-enriching” level. While the other levels involve physical satisfaction, that is, the need in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called “luxury” items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing.
On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.
According to the passage, man will begin to think about such needs as housing and clothing only when .

A.he has saved up enough money
B.he has grown dissatisfied with his simple shelter
C.he has satisfied his hunger
D.he has learned to build houses

It can be inferred from the passage that by the end of World War Ⅱ, most Americans .

A.were very rich
B.lived in poverty
C.had the good things on the first three levels
D.did not own automobiles

Which of the following is NOT related to “physical satisfaction” ?

A.A successful career. B.A comfortable home.
C.A good meal. D.A family car.

What is the main concern of man on the fourth level?

A.The more goods the better.
B.The more mental satisfaction the better.
C.The more “luxury” items the better.
D.The more earnings the better.

The story goes that some time ago, a man punished his 3-year-old daughter for wasting a roll of gold wrapping paper. Money was tight and he became infuriated(愤怒的) when the child tried to decorate a box to put under the Christmas tree. Nevertheless, the little girl brought the gift to her father the next morning and said, "This is for you, Daddy."
The man was embarrassed by his earlier overreaction, but his anger flared again when he found out the box was empty. He yelled at her, stating, "Don't you know, when you give someone a present, there is supposed to be something inside? The little girl looked up at him with tears in her eyes and cried, "Oh, Daddy, it's not empty at all. I blew kisses into the box. They're all for you, Daddy."
The father was crushed. He put his arms around his little girl, and he begged for her forgiveness.
Only a short time later, an accident took the life of the child. It is also told that her father kept that gold box by his bed for many years and, whenever he was discouraged, he would take out an imaginary kiss and remember the love of the child who had put it there.
In a very real sense, each one of us, as humans beings, have been given a gold container filled with unconditional love and kisses from our children, family members, friends, and God. There is simply no other possession, anyone could hold, more precious than this.
The 3-year-old girl was punished by her father for ________.

A.wasting gold
B.wasting wrapping paper
C.putting the box under the Christmas tree
D.bringing the gift to her father

What’s inside the box according to the little girl?

A.nothing B.air C.kisses D.gold wrapping paper

Choose the best title for the passage.

A.The kisses in the box. B.A girl and his father
C.A love story D.The box under the Christmas tree.

Do you sometimes argue about what seems to you to be simple fact? Do you argue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit?
If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant’s trunk said it was like a snake. The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear as he touched the animal’s tusk. The fourth, who got hold of the elephant’s tail insisted that it was like a rope. The fifth man said it looked like a tree as he put his arms around one of the elephant’s legs. The sixth, who was tall and got hold of the elephant’s ears, said it was like a huge fan.
Each man’s idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.
To see how hard it is for even one person to make up his mind about a“simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water in the third. Now put your left hand in the ice water. Put your right hand in the hot water. After thirty seconds, put both hands in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it’s hot!
What makes people think about simple facts differently?

A.The fact that simple facts differ from one another.
B.The fact that people have different experience in the same simple fact.
C.The fact that people often disagree with one another.
D.The fact that it’s hard to make up one’s mind about simple facts.

Which of the following temperatures can the word “lukewarm” be applied to?

A.Around 1℃ B.Above 60℃ C.Around 25℃ D.Below 0℃

After reading the last paragraph, we may think of.

A.Newton’s law B.Gallileo’s theory of falling objects
C.Einstein’s theory of relativity D.Marx’s On Capital

The main idea of this passage is.

A.people often judge something according to his own experience
B.people often agree about simple facts
C.it’s hard for a person to make up his mind about a simple fact
D.don’t care too much about simple facts
