Below is some adviee on how to prevent cancer.
Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon 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.
Drink Pomegranate（石榴）Juice
The deep red juice of the pomegranate contains various chemicals, 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(阻碍) the growth of lung cancer.
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!
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.
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 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.To prevent yourself from catching colon cancer, you should eat ____ as often as possible.

Researchers have found that people's mental abilities hit the highest point at 22 before beginning to get worse just five years later.
Professor Timothy Salthouse said the results told us that treatment which was planned to prevent or make overage-connected conditions better may need to start earlier, long before people become retired (退休).
"Almost half of those over 50 is not clear about the main cause of the fall of mental abilities. Results show that the age-connected cognitive decline (认知衰退) begin in healthy, educated adults when they are in their 20s and 30s, " he said. Tests like those are often used to show mental disabilities and the falling, including dementia (痴呆症).
The research by the University of Virginia found that in nine out of 12 tests the common age at which the top performance appeared was 22.
The first age at which performance was much lower than the highest scores was 27—for three tests about reasoning, speed of thought and space imagination.
Memory was shown to fall from the average age of 37. In the other tests, poorer results were shown by the age of 42.
However, the report published in the magazine "Neurobiology Of Ageing", found that abilities that are based on collected knowledge, such as performance on tests of getting vocabulary (词汇) or general information, increased until at the age of 60.
The study of 2, 000 men and women lasted over seven years. The people attending the study, aged between 18—60, were asked to do picture puzzles, remember words and stories and mark patterns in letters and signs.
Twenty-seven has long had unhelpful connotations (隐含意义), as it is the age at which many popular musicians died, including Jimi Hendrix, Jim Morrison, Brian Jones, Janis Joplin and Kurt Cobain. Which of the following is NOT true?
| A．People's mental abilities perform best at 22. |
| B．People's mental abilities begin to get worse at 27. |
| C．People's mental abilities have nothing to do with age. |
| D．Many people don't know what cause mental abilities' falling. |
The tests of the study were planned to find __________.
| A．the difference of males and females |
| B．ways to help the people find better jobs |
| C．better ways to treat dementia of some old people |
| D．age has an effect on performance of mental abilities |
People at the age of 27 perform worse mainly at __________.
| A．reasoning, speed of thought and space imagination |
| B．getting vocabulary or general information |
| C．all of the mental abilities |
| D．only the ability of memory |
What is the best title of the passage?
| A．Twenty-seven Has Long Been Unhelpful |
| B．Mental Abilities Start to Fall at 27 |
| C．27 Musicians Died Earlier |
| D．How to Get Better Mental Abilities |
The European Union announced plans on Tuesday to temporarily ban the use of animal cloning for food production, while allowing imports of food derived from the offspring (后代) of clones from the United States and elsewhere.
The report from the European Commission followed a call by EU lawmakers in July for a total ban on food derived from cloned animals and their traditionally bred offspring, citing ethical concerns over the industrial production of cloned meat.
The Commission said a temporary five-year EU ban on cloning for food production was justified on animal welfare grounds, but said banning imports of food from the offspring of clones was unnecessary and would disrupt global trade.
"Food from cloned animals is safe. In fact, the scientific opinion is that it cannot be differentiated in any way from food normally bred animals. The issue is animal welfare," EU Health and Consumer Commissioner John Dalli told reporters.
Food derived from the offspring of clones presents no such animal welfare issues, and banning its sale and import would be impossible because the origin is untraceable, Dalli said.
"Such a prohibition would lead to a ban of imports of any food of animal origin (meat, milk and processed products) from third countries allowing the cloning technique," the report said.
"We're not going to regulate for the world," Dalli added.
But animal welfare groups criticized the Commission's decision, saying it had bowed to pressure from third countries.
"We do not accept the Commission's position that it would be impossible to enforce a ban that includes the offspring of cloned animals, as (other) meat traceability systems are already in place, " said Sonja Van Tichelen, director of the Eurogroup for Animals. From the passage we can infer that the ban is __________.
| A．justified | B．welcome |
| C．controversial | D．meaningless |
Which of the following is TRUE according to the passage?
| A．The ban is permanent. |
| B．The imports of food from the offspring of clones are not banned. |
| C．Animal welfare groups support the ban. |
| D．The ban has been put into effect. |
Which of the following is the reason for Commission's decision on the ban according to animal welfare groups?
| A．The origin of food derived from the offspring of clones is Untraceable. |
| B．Food from cloned animals is safe. |
| C．The issue is for animal welfare. |
| D．The pressure comes from third countries. |
What might be the most suitable title for the passage?
| A．The plans of the European Union |
| B．A temporary five-year EU ban |
| C．The EU proposes a ban on animal cloning for food |
| D．The danger of food derived from cloned animals |
In the modern world more and more people meet the problem of identity. The most interesting example is that of a so-called "banana", which refers to an American who has an Asian face but holds Western values.
In Shanghai, there now live a group of people from abroad. They look no different from the locals and speak fluent Chinese or even Shanghai dialect, but when it comes to writing Chinese characters, they are almost illiterate (文盲). Jack is such an example. He never learned to read or write Chinese characters, which he finds mysterious and difficult. From time to time, he files to the US as he does not feel Shanghai is where he comes from. "But when I am in the States, I feel that's not my home either," he said.
At De Gaulle Airport in France, there is a Swiss man who has been living in the waiting-room for a long time because he lost his passport during his travels. He was refused entry into several countries. But when he was eventually allowed to return to Swizerland, he refused to leave the airport. His reason was very simple—"I am sure who I am. I need no acknowledgement from others," he said during an interview. For this reason he was honored by the Western media as "the Hero of identity".
As the Internet becomes more and more popular, the problem of identity becomes more serious. In a virtual world, people can have different addresses registered with different names. In the Internet chat room, even one's gender (性别) is hard to determine. It seems that in the global village, people are saying hello every day to each other without knowing whom they are talking to.
What will be the next crisis (危机) of identity? With the development of cloning technology, it might be: who is the real "I"? What does the passage mainly talk about?
| A．The importance of identity. |
| B．The crisis of identity. |
| C．Differences between Eastern and Western cultures. |
| D．Difficulty in living in foreign counties. |

A "banana" in the passage is in fact an __________.
| A．American traveling to Asia |
| B．American keeping Eastern culture |
| C．American born in Asia |

| C．only people traveling abroad have problems of identity |
| D．people don't need to worry about identity |
It is common to consider learning as something that takes place in school, but much of human learning occurs outside the classroom, even from birth and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human-service workers need to understand how certain experiences change people's behaviors. Employers, politicians, and advertisers make use of the principles of learning to affect the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain. Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later outputs knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person's experiences. The author thinks "Learning" in the passage most refers to __________.
| A．life-long learning |
| B．family learning |
| C．learning after graduation |
| D．behavior learning |
The underlined "siblings" in the second paragraph probably means __________.
| A．teachers | B．classmates |
| C．doctors | D．brothers or sisters |
Which period of children's life do they begin to learn how to behave well according to the passage?
| A．After they go into society. |
| B．Before they enter school. |
| C．When they are at school. |
| D．Before they are born. |
Which of the following is WRONG according to the passage?
| A．As a matter of fact, learning begins with formal school education. |
| B．Teachers need to understand the best ways to educate their students. |
| C．People need to understand how certain experiences change their behaviors. |
| D．Employers should study the principles of learning to manage their workers well. |
