Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.

Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them, sense them, without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated（辐射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
【小题1】Which of the following statements is true?
| A．Nuclear radiation is just like common radio waves. |
| B．Nuclear radiation can cause cancer to human beings. |
| C．Nuclear radiation can be detected by human senses. |
| D．Nuclear radiation can be safe to human beings if its level is low. |
| A．By damaging its heart. | B．By killing a few cells. |
| C．By hitting any place in its body. | D．By killing many cells in important organs. |
| A．die of cancer after many years | B．die immediately |
| C．have a child who may be born weak | D．all of the above |

Health experts are calling for action to increase cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community to fight cancer actively, saying it should be fought in the way HIV/AIDS has been fought in Africa.
Cancer kills more than 7.5 million people a year worldwide. Almost two-thirds are in low-income and middle-income countries.
They discover cancer kills more people in developing countries than AIDS, tuberculosis (肺结核) and malaria (疟疾) combined. But the world spends only 5% of its cancer resources in those countries.
Felicia Knaul from Harvard Medical School was one of the writers of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.
Felicia Knaul says, “And we are seeing how this is attacking young women. It’s the number two cause of death in Mexico for women thirty to fifty-four. All over the developing world, it’s the number one cancer-related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.”
Professor Knalul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower-cost drugs.
【小题1】What would be the best title for the passage?
| A．Cancer – a leading cause of death in poor countries |
| B．What should we do in preventing and treating cancer? |
| C．What makes the first killer in developing countries? |
| D．Experts urge more efforts to fight cancer. |
| A．many Mexican women suffer from breast cancer |
| B．there is not enough medicine for cancer there |
| C．many Mexican women can’t afford medical care |
| D．patients with breast cancer are treated differently |
| A．breast cancer is a great threat to young women |
| B．people don’t pay enough attention to breast cancer |
| C．breast cancer is the second killer among women in Mexico |
| D．patients can be treated effectively in developing countries |
| A．The cancer patients. | B．The health experts. |
| C．Community health workers. | D．Young women. |
| A．The number of cancer cases is decreasing. |
| B．HIV/AIDS is not being taken seriously in Africa. |
| C．Over 7.5 million people die of cancer every year. |
| D．It is very expensive to treat cancer. |

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.
"How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.
The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.
Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.
The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.
Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.
We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
【小题1】The underlined word is best replaced by __.
| A．Injure | B．Benefit | C．Push | D．Shape |
| A．All physical activities are equally harmful. |
| B．Yoga causes much less injuries than other physical activities. |
| C．Similar researches have been done before. |
| D．Yoga, like any other form of exercise, can hurt people. |
| A．Teachers lack the knowledge of students’ limits. |
| B．Modern lifestyle decreases our flexibility. |
| C．The body doesn’t tell when you are in real pain. |
| D．Students themselves might not be in good physical condition. |
| A．It’s a shame not to practice yoga. |
| B．One should push the limits in order to be perfect. |
| C．The majority should give up yoga for it may cause harm. |
| D．One should enjoy the physical and mental benefit that yoga brings. |

“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 the 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．objective | B．costly | C．unreliable | D．illegal |
| 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 |
| 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 |

FDA proposed the most sweeping food safety rules in decades, requiring farmers and food companies to be more cautious in the wake of deadly outbreaks in peanuts, cantaloupe (瓜），and leafy greens.
The long-overdue regulations are aimed at reducing the estimated 3,000 deaths a year from foodbome illness. Just since last summer, outbreaks of listeria (李氏杆菌）in cheese and salmonella(沙门氏菌）in peanut butter, cantaloupe and mangoes have been linked to more than 400 illnesses and as many as seven deaths, according to the Centers for Disease Control. The actual number of those sickened is likely much higher.
The FDA’s proposed rules would require farmers to take new precautions against contamination (污染）,to include making sure workers5 hands are washed, irrigation (灌溉） water is clean, and that animals stay out of fields. Food manufacturers will have to submit food safety plans to the government to show they are keeping their operations clean.
Many responsible food companies and farmers are already following the steps that the FDA would now require them to take. But officials say the requirements could have saved lives and prevented illnesses in some of the large-scale outbreaks that have hit the country in recent years.
In a 2011 outbreak of listeria in cantaloupe that claimed 33 lives ，for example, FDA inspectors found pools of dirty water on the floor and old, dirty processing equipment at the Colorado farm where the cantaloupes were grown. In a peanut butter outbreak this year linked to 42 salmonella illnesses ，inspectors found samples of salmonella throughout a New Mexico peanut processing plant and multiple obvious safety problems ，such as birds flying over uncovered trucks of peanuts and employees not washing their hands.
Under the new rules, companies would have to lay out plans for preventing those sorts of problems and how they would correct them.
“The rules go very directly to preventing the types of outbreaks we have seen/，said Michael Taylor, FDA’s deputy commissioner for foods.
【小题1】The main task of FDA is probably______
| A．to protect and promote the public health |
| B．to help those sickened recover |
| C．to research on food safety measures |
| D．to deal with water pollution |
| A．inspecting the whole process of food production |
| B．improving food processing equipment on farms |
| C．preventing water pollution in food production |
| D．urging food companies to lay out plans |
| A．Inspectors. | B．Farmers |
| C．Manufacturers. | D．Workers. |
| A．The new regulations should have come into practice earlier. |
| B．The 2011 outbreak of listeria is the most serious ever. |
| C．Farmers and food companies are strongly against the new rules. |
| D．Colorado and New Mexico are worst hit by food pollution. |

I’m glad to find this comment which has some sort of support in this quest（寻求）I have to eat raw（未煮熟的）foods. I’m an unhealthy 49 years old and have come to the conclusion that it’s now or never, so I am taking a dive into the raw eating lifestyle.
I have to cook for my family and prepare what they want to eat. I’m trying to plan out this better so I have some of these unusual foods ready for myself.
I’ve read several books written by Ann Wigmore and like her approach to the living foods.
Last week I attempted fasting（禁食）and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn’t sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family.
This week I started to make a drink called rejuvelac made of sprouted wheat（芽麦）. This is fairly new to do for me and the drink smelled sort of musty（发霉的）and tasted kind of like a musty lemon. The kids tasted it and almost threw up but surprisingly it tasted good to me. It is supposed to help in digestion（消化）.
I’ve made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I’m very frustrated(受挫的) with the smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress.

India has many festivals, with some celebrations that last for weeks. However, none of them come even close to Holi, India’s most colorful and fun festival. Celebrated on the day following the full moon, this year’s festival happens to be on March 19th.
As with most Indian festivals, this one also has many different folk stories. Most of them center around the success of good over evil. The most popular one is about a king, who hates his son Prahlada for loving the creator of the Universe—Lord Vishnu. When every attempt to stop him fails, his sister, Holika believed to be immune(免疫的) to fire, joins in the effort by inviting the young boy to sit with her inside a huge fire. Helped by the power of Lord Vishnu, Prahlada escapes safely, while the evil Holika is burned to death. To remember this event, huge outdoor fires are lit in the night before Holi in order to clean the air of evil spirits and to celebrate the death of the evil.
So what’s so great about this day? While there are some fun parades(游行) and folk songs and dance performances, the most fun of all is walking to the streets and splashing(泼洒) people with water guns and dry colors and even covering them with entire buckets of colored water. On this day, everybody is fair game, no matter how old or how young.
At about midday, the splashing comes to an end and people living close to oceans or rivers usually take a bath in the water to clean themselves before going home to a delicious home-made big dinner and a well-deserved short sleep, following this full day of fun and activities.
【小题1】Why does the king dislike his son Prahlada?
| A．Because Prahlada doesn’t love him. |
| B．Because Prahlada is rude to Holika. |
| C．Because Prahlada loves Lord Vishnu. |
| D．Because Prahlada concentrates on his own success. |
| A．with the help of Lord Vishnu |
| B．because of his good luck |
| C．by beating his aunt Holika |
| D．using his amazing talent |
| A．fights against others fairly |
| B．enjoys splashing people |
| C．plays a trick on others |
| D．is the aim of splashing water |
| A．they have got dirty with dry colors and colored water |
| B．going home with colored water means bad luck |
| C．they believe clean water will bring good luck |
| D．taking a bath shows their true love for Lord Vishnu |
