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， 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 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.
【小题1】 According to the passage， people are advised to take more Vitamin D because_________.
| A．it is nutritious |
| B．it can‘t harm people’s health |
| C．it is not taken enough every day |
| D．it can lower cancer risk |
| A．Have more meat | B．Have some sunshine |

Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief above was longlived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ.Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many firsttime parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary，Mary Ruebush，an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
【小题1】The kings of France and England in the 16th century closed bath houses because ________.
| A．they believed disease could be spread in public baths |
| B．they thought bath houses were too dirty to stay in |
| C．they lived healthily in a dirty environment |
| D．they considered bathing as the cause of skin disease |
| A．Approving. | B．Afraid. | C．Curious. | D．Uninterested. |
| A．By providing examples. |
| B．By making comparisons. |
| C．By following the order of importance. |
| D．By following the order of time. |
| A．To stress the role of dirt. |
| B．To introduce the history of dirt. |
| C．To present the change of views on dirt. |
| D．To call attention to the danger of dirt. |

In today's fast-paced (快节奏) society, few people take time to enjoy the midday meal．Most of us just rush right through it. We grab a quick salad, or buy a sandwich and eat at our computers, Sometimes, if there is a deadline around the corner, we just skip lunch．
The development of technology hasn't done our eating habits much good either．We are constantly distracted by e-mail, social media, and 24 - hour news．Even when we do sit down for lunch, we are more connected to our hand - held electronic devices．
Long working hours can cause all kinds of health problems, and many developed countries have put in place labor laws specifically regarding the lunch break．These laws give employees the right to take a break during a long work shift, but it's up to them whether they do so or not．
Frank Partnoy, a former Wall Street trader, says that employers should encourage workers to take time off for lunch．This is because long lunch breaks can benefit both individuals and society.
Writing in The Guardian, Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective（认识）． A break from work allows us to think strategically and outside the box．It also puts our daily tasks into a broader context（背景）．
What we eat at lunch is also important．In Partnoy' s opinion, a fast food lunch is more harmful than not having lunch at all． And it's not just about calories and unhealthy food．Recent studies show that fast food also has negative effects on how we think．
However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down, something that hardly can be achieved in a noisy and over — packed fast food chain．
Despite these benefits, some employees might still be unwilling to take time off for lunch．Partnoy's suggestion? Make skipping lunch difficult: Employers could ask workers to fill out a form stating their reasons for skipping the meal．
【小题1】What does the underlined phrase "skip lunch" mean in the first paragraph?
| A．have a quick lunch | B．don't have lunch |
| C．work while having lunch | D．take a lunch break |

WASHINGTON－School lunches have been called many things, but a group of retired military officers is giving them a new label: national security threat.
That's not a reference to the mystery meat served up in the cafeteria line either. The retired officers are saying that school lunches have helped make the nation's young people so fat that fewer of them can meet the military's physical fitness standards, and recruitment will be difficult.
A new report being released Tuesday says more than 9 million young adults, or 27 percent of all Americans ages 17 to 24, are too overweight to join the military. Now, the officers are advocating for passage of a wideranging nutrition bill that aims to make the nation's school lunches healthier.
The military group acknowledges that other things keep young adults out of the armed services, such as a criminal record or the lack of a high school diploma. But weight problems that have worsened over the past 15 years are now the leading medical reason that recruits are rejected.
Although all branches of the military now meet or exceed recruitment goals, retired Navy Rear Adm. James Barnett Jr., a member of the officers group, says the obesity trend could affect that.
“When over a quarter of young adults are too fat to fight, we need to take notice，” Barnett said. He noted that national security in the year 2030 is “absolutely dependent” on reversing child obesity rates.
This isn't the first time the military has gotten involved in the debate over school lunches. During World War Ⅱ， military leaders had the opposite problem, reporting that many recruits were rejected because of stunted growth and inadequate nutrition. After the war, military leaders pushed Congress to establish the national school lunch program so children would grow up healthier.
Today, the group is urging Congress to eliminate junk food and highcalorie beverages from schools, put more money into the school lunch program and develop new strategies that help children develop healthier habits.
【小题1】What is the main problem of the lunches in schools according to the military officers?
| A．The meat in the lunches is mysterious. |
| B．The lunches are too expensive. |
| C．The lunches contain too much fat. |
| D．There is inadequate nutrition in the lunches. |
| A．slow in mind | B．state of being fat |
| C．quick in movement | D．lack of confidence |
| A．The lunches in American schools are not very healthy. |
| B．During World War Ⅱ，many people could not join the army because of overweight. |
| C．According to the author , overweight was the key reason why many recruits were rejected. |
| D．By now, Congress hasn't eliminated junk food and highcalorie beverages from schools. |
| A．School lunches: a national security threat? |
| B．National security in danger ? |
| C．Retired officers tired of school lunches |
| D．The recruitment of 2030 |

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism (新陈代谢) that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious（恶性的）circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
【小题1】What is the main purpose of this passage?
| A．To advocate eating more raw and whole foods. |
| B．To tell the differences between raw and processed foods. |
| C．To inform people of the harm of processed foods. |
| D．To warn people of the problem of obesity. |
| A．it is essential for people to protect their vital organs |
| B．foods with natural enzymes help people keep fit |
| C．we’d better be cautious about raw and whole foods |
| D．giving up cooked and refined foods is a new lifestyle |
| A．destroy body’s cells | B．are difficult to digest |
| C．may lead to obesity | D．stop body’s metabolism |
| A．Active approaches to avoid acid. |
| B．Different causes of acid accumulation. |
| C．Correct ways to cook raw foods. |
| D．Suitable types of raw and whole foods. |
| A．Processed foods are good for our appetite mechanism. |
| B．Eating the right types of raw and whole foods does good to our body. |
| C．The accumulation of acid in the digestive tract makes digestion more effective. |
| D．Processed foods also comfort the digestive tract. |

Was the London Olympics a success? Many people hold different opinions. However one thing is certain, London could win a gold medal for hosting the “greenest” Games ever, BBC News reported.
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste. and transport. But things had to be different in London because seven years ago it bid for the Olympics through the concept of “a One Planet Olympics”.
What is most impressive is that London used the construction of the Olympic Park as an opportunity to clean up polluted areas — 2 million tons of contaminated (被污染的) soil were removed and 200 old factory buildings, were torn down, according to sustainablebusiness.com. But that’s not all —. 99 percent of the debris (废瓦砾) were reused to build the Olympic Park. For example, part of the Olympic Stadium’s roof is made from 2,500 tons of steel tubes recycled from old gas pipelines.
As well as using recycled materials, all venues were built with green building techniques. The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed. Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent, according to sustainablebusiness.com.
The effort that London made to deal with waste also deserves praise. Water used for drinking and watering plants was from collected rainwater or recycled wastewater. In this way. about 30-40 percent less water was used in total. Waste food packages were either recycled or processed and turned into renewable energy.
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport. For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions.
The clean anti-doping (反兴奋剂) result also added to the greenness of the Games. The International Olympics Committee (IOC) said that the devices used this time were the most accurate and advanced. Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games.
【小题1】To make the Olympic Park green, London _______.

When your parents advise you to “get an education” in order to raise your income, they tell you only half the truth. What they really mean is to get just enough education to provide manpower（人力资源）for your society, but not so much that you prove an embarrassment to your society.
Get a high school diploma, at least. Without that, you will be occupationally dead unless your name happens to be George Bernard Shaw or Thomas Alva Edison, and you can successfully dropout in grade school.
Get a college degree, if possible. With a B. A., you are on the launching pad. But now you have to start to put on the brakes. If you go for a master’s degree, make sure it is an M.B.A., and the famous law of diminishing(逐渐减少的) returns begins to take effect.
Do you know, for instance, that long-haul truck drivers earn more per year than full professors? Yes, the average salary for those truckers was $24000 while the full professors managed to earn just $23030.
A doctorate is the highest degree you can get. Except for a few specialized fields such as physics or chemistry where the degree can quickly be turned to industrial or commercial purposes, if you pursue such a degree in any other field, you will face a future which is not bright. There are more doctors unemployed or underemployed in this country than any other part of the world.
If you become a doctor in English or history or anthropology or political science or languages or—worst of all—in philosophy, you run the risk of becoming overeducated for our national demands. Not for our needs, mind you, but for our demands.
Thousands of doctors are selling shoes, driving cars, waiting on table, and endlessly filling out applications month after month. They may also take a job in some high school or backwater(闭塞) college that pays much less than the doorkeeper earns.
You can equate the level of income with the level of education only so far. Far enough, that is, to make you useful to the gross national product, but not so far that nobody can turn much of a profit on you.
【小题1】 According to the writer, what the society expects of education is to turn out people who ______.
| A．will not be a disgrace to society |
| B．will become loyal citizens |
| C．can take care of themselves |
| D．can meet the nation’s demand as a source of manpower |
| A．they are improperly educated |
| B．they are of little commercial value to their society |
| C．there are fewer jobs in high schools |
| D．they prefer easier jobs that make more money |
| A．with diplomas |
| B．who specialize in physics and chemistry |
| C．who are valuable to the gross national product |
| D．who receive little education |
| A．Bernard Shaw didn’t finish high school, nor did Edison. |
| B．One must think carefully before pursuing a master’s degree. |
| C．The higher your education level, the more money you will earn. |
| D．If you are too well-educated, you’ll be overeducated for society’s demands. |
| A．a means of providing job security and financial security and a means of meeting a country’s demands for technical workers |
| B．a way to broaden one’s horizons |
| C．more important than finding a job |
| D．an opportunity that everyone should have |
