Below is some advice on how to prevent cancer:
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 remarkably cut their prostate(前列腺) cancer risk by 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. So don’t skimp(节省)on the Sushi!
6. 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.
7. 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.

People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding (繁殖) rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical (等级的) societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”
When a goby grows to within 5-10% of the size of its larger competitor, it .

A.faces danger B.has breeding rights
C.eats its competitor D.leaves the group itself

Science Fiction
The science fiction type of entertainment is considered by most to be fathered by Jules Verne (A Journey to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sci-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.
Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969 location at Cape Canaveral, Florida.
One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in 1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author’s name has been made into an adjective—Orwellian—and has become a warning descriptor for situations where privacy is lost and the individual becomes sacrifice under a totalitarian(极权主义) government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record that still stands.
What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. Advances in genetics(遗传学) cause fantasies of the end of disease, horrors of eugenics(优生学), and thrillers where creatures disappearing long ago are brought back to life. The science fiction author’s self-determined role is that of field glasses for humanity—searching the world of future possibilities upon the road which we are traveling.
What can science fiction offer to people?

A.A forecast of how a new discovery could influence mankind.
B.A thoughtful look at the present drawbacks of technology.
C.An analysis of why a new technology could be used to harm human.
D.A thoughtful look at the past and what brought us to this point in history.

Which of the following best summarizes the description of Nineteen Eighty-Four?

A.A prediction of future technologies.
B.A warning of cruel and unfair ruling.
C.The consequence of scientific findings.
D.An imaginary perfect world of freedom.

From the passage we can learn that _____.

A.Nineteen Eighty-Four adopted some popular terms
B.H.G. Wells predicted the Internet in the late 1800s
C.Cape Canaveral was mentioned in Jules Verne’s fiction
D.Star Trek movie series were based on space exploration

According to the author, what is the role of science fiction in society?

A.A moral compass.
B.A reference of technology.
C.A record of science development.
D.A consideration of possibilities.

Does money buy happiness? Not! Ah, but would a little more money make us a little happier? Many of us smirk(傻笑,假笑) and nod. There is, we believe, some connection between financial fitness and emotional fulfillment. Three in four American college students—nearly double the 1970 proportion— now consider it “very important” or “essential” that they become “very well off financially”. Money matters.
But a surprising fact of life is that in countries where nearly everyone can afford life’s necessities, increasing wealth matters surprisingly little. The connection between income and happiness is “surprisingly weak,” observed University of Michigan researcher Ronald Inglehart in one 16-nation study of 170,000 people. Once comfortable, more money provides diminishing returns(报酬递减). The second piece of pie, or the second $100,000, never tastes as good as the first. Even lottery winners and the Forbes’ 100 wealthiest Americans surveyed by University of Illinois psychologist Ed Diener have expressed only slightly greater happiness than the average American. Making it big brings temporary joy. But in the long run wealth is like health: its complete absence can create suffering, but having it doesn’t guarantee happiness. Happiness seems less a matter of getting what we want than of wanting what we have.
Has our happiness, however, floated upward with the rising economic tide? Are we happier today than in 1940s, when two out of five homes lacked a shower or tub? Actually, we are not. Since 1957, the number of Americans who say they are “very happy” has declined from 35 to 32 percent. Meanwhile, the divorce rate has doubled, the teen suicide(自杀) rate has increased nearly three times, the violent crime rate has gone up nearly four times, and depression has mushroomed. Economic growth has provided no boost to human morale. When it comes to psychological well being, it is not the economy.
I call this soaring wealth and shrinking spirit “the American paradox.” More than ever, we have big houses and broken homes, high incomes and low confidence, secured rights and reduced civility. We are good at making a living but often fail at making a life. We celebrate our prosperity(繁荣) but long for a purpose. We treasure our freedoms but long for connection. In an age of plenty, we feel spiritual hunger.
Which of the following statements best expresses the author’s view?

A.The more money we earn, the less returns we have.
B.The more money we earn, the happier we would be.
C.In the long run, money cannot guarantee happiness.
D.In the long run, happiness grows with economy.

“The second $100,000 never tastes as good as the first” because _____.

A.it is not so fresh as the first $100,000
B.it is not so important as the first $100,000
C.profit brought by it is less than that from the first $100,000
D.happiness brought by it is less than that from the first $100,000

According to the passage, people do well in making a living but don’t _____.

A.have any primary aim B.know how to spend money

My favorite English teacher could draw humor out of the driest material. It wasn’t forced on us either. He took Samuel Johnson’s dictionary, Addison’s essays, and many other literary wonders from the eighteenth century and made them hilarious, even at eight o’clock in the morning. The thing that amazed me most was that the first time I read these works on my own some of them seemed dead, but the second time, after his explanation, I couldn’t believe that I hadn’t seen the humor. The stories and poems and plays were suddenly filled with allusions(典故) and irony andhilarious moments. I learned more from him than from any other teacher.
My least favorite English teacher also made people laugh. Some students found him to be wonderfully funny. Many others did not. He assigned journals over a six week period, to be written in every day. At the end of the six weeks I had a notebook full of bits and pieces about my ideas, short stories, reactions to what we had read, and so on. Our teacher announced that we would be grading each other’s journals. Mine was passed to Joe, that class clown, who always behaved in a funny or silly way. He saw it fit to make joke of and said, “This writing isn’t fit to line the bottom of a birdcage.” Our teacher laughed at that funny remark. It hurt me so much that the anger from it has driven my writing and teaching ever since.
So what makes the difference? Humor is one of the most powerful tools teachers or writers have. It can build up students and classes and make them excited about literature and writing, or it can tear them apart. It is true that humor is either productive or counter-productive and self-defeating.
The passage mainly discusses _____.

A.teaching B.literature
C.humor D.knowledge
