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.

阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。

Time, a faithful company of our life, is a universal topic. People are always curious about what it is, how it travels and who it meets.

Stephen Hawking, one of the world’s smartest physicists, once said. “I’m fascinated by time.”

Many of us are, and the popularity of time travel novels, movies and TV series has proved that. After Palace and Startling by Each Step achieved astonishing ratings last year, Palace 2 aired on January 20, attracting time travel fans back to TV.

Woody Allen’s movie Midnight in Paris achieved great success. It was nominated for Best Picture, Directing, Original Screenplay and Art Direction for the 2012 Academy Awards.

Dream of heroism

Time travel TV series and movies connect both today and the past, thus offering room for imagination. Imagination creates a chance for the young to fulfill a dream that is hard to achieve in reality.

Chinese writer Xi Juan is a pioneer of time-travel stories in China. In 1993 she published a love story about a young woman time traveling to ancient times. The leading role’s modern personality and perception of love help her win the heart of a cool, handsome martial art master. Such a plot satisfies female fans’ love fantasy.

Starting from the late 1990s, novels about men traveling back to the past prevailed (盛行), with a Step into the Past as the most popular example. In these stories, the male leading roles accomplish great things with their modern skills and wisdom.

It is usually “a dream of heroism come true”, along with enviable romances.

Eye candy

“I’m hooked by the shows because they are characterized by dramatic and poetic love and have eye-pleasing actors,” Xia Xiaoyan, who works for a foreign-owned enterprise in Shanghai, explained her love for time travel TV series.

Her comment echoes a 2011 survey by Creat Marketing Research Co Ltd in China. When asked about what is so appealing about time travel TV series, 21 percent of respondents answered, “These attractive characters.”

A bigger reason behind the popularity of time travel stories, however, is the relaxation they offer, according to the survey.

Cai Yinong agrees. “Many people are facing tremendous pressure in their fast-paced lives, so this genre is more relaxing than other shows as it provides people with a terrific outlet to escape reality,” Cai told China Daily.

Cultural homesickness

“Which dynasty would you like to live in if you could travel to the past?” asked a survey launched by Shanghai University and Shanghai Social Sciences Association last December.

About 60 percent of the 2,543 respondents chose Tang Dynasty, while Qing Dynasty, and the Spring and Autumn and Warring States periods were the other top two destinations.

The survey results reflects people’s definition of the good days: prosperous economy and culture, steady society, fair and uncorrupted politics, and opening up to the outside world.

As for the movie Midnight in Paris, it features modernity versus cultural homesickness. The New York Times commented, “The past seems so much more vivid, more substantial, than the present. The good old days are so attractive because we were not around, however much we wish we were.”

More than half of the parents in the United States are helping, or have helped, support their adult children who have been hit by high unemployment and poor wages(工资), according to a new survey. It showed that present economic conditions are discouraging young adults from leaving home and forcing those who have already gone, so-called boomerang kids, to return.
“Parents are continuing their financial involvement longer than we expected,” said Ted Beck, president of National Endowment for Financial Education (NEFE).
About 60 percent of parents questioned in the survey said they’re helping their adult children who are no longer in school financially. Half are providing housing and nearly half are helping with living expenses.
For an increasing number of adult children, the situation is bad. Two-thirds of adult children, aged 18 to 39, who are not in school said they faced tougher financial pressures than previous generations, according to the survey. And nearly one-third of parents agreed that it was easier for them to find their financial feet than for their children.
Parents are helping their children out of genuine concern because they do not want to see them struggle. But Beck said that parents who make sacrifices(牺牲) to help their adult children should be careful about their own finances.
“If you are taking on extra debt or delaying(推迟) retirement to help your adult child, you could be making a mistake and putting your own financial future in danger,” Beck warned.
Boomerang children can also cause other problems for their parents. Thirty percent of parents said they had given up privacy since their adult children moved back home, while more than a quarter have taken on added debt, and seven percent have delayed retirement. But the survey also showed 42 percent of adult children living at home are helping with the cooking and cleaning.
【小题1】According to the text, boomerang kids refer to ____.

Most drinks stating that they are fruit­ flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

“Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be non­existent，” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. __1__ It will increase profits, and consumers won't always realize they are being tricked.”

Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry­ flavored products sold in stores.    __2__  Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

__3__ Let's take jam as an example. Some strawberry­ flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.

__4__ Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading.   __5__ Unfortunately, it is also legal and widespread，” Tokelove said. “It's time to take measures to protect the consumers' rights.”

E. It is important and necessary to demand a small amount of flavoring in the products.

F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.

G. The Food Commission suggested all flavors used in a product should be listed on the packaging.
