Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化化学物质) that may help stop the cell damage that can lead to disease.Researchers have been studying green tea’s effect on everything from cholesterol (胆固醇) to the risk of certain cancers，with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”，or problems with daily activities or basic needs，such as dressing or bathing.
Specifically，almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled，compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older.Green tea lovers generally had healthier diets，including more fish，vegetables and fruit，as well as more education，lower smoking rates，fewer heart attacks and strokes，and greater mental sharpness.They also tended to be more socially active and have more friends and family to rely on.But even with those factors accounted for，green tea itself was tied to a tower disability risk，the researchers said.
People who drank at least five cups a day were onethird less likely to develop disabilities than those who had less than a cup per day.Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (缓冲) against disabilities，lead researcher Yasutake Tomata did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts，they do contain caffeine and small amounts of vitamin K，which means it could affect drugs that prevent blood clotting (凝固)．

| A．Fathers. |
| B．Brothers. |
| C．People of the same age. |
| D．People living in the same neighborhood. |

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
【小题1】From Paragraph 1, we learn that ________.
| A．diet products fail to bring out people’s potential |
| B．people are fed up with diet products |
| C．people have difficulty in choosing diet products |
| D．diet products are misleading people |
| A．hesitate before they enjoy diet foods |
| B．pay attention to their own eating habits |
| C．watch their weight rather than their diet |
| D．try out a variety of diet foods |
| A．losing weight is effortless |
| B．diet products bring no pain |
| C．it costs a lot to lose weight |
| D．diet products are free from calories |
| A．lack basic nutrients | B．are over-consumed |
| C．are short of chemicals | D．provide too much energy |

Comera is the only place in the world which has a whistle(口哨)language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley cannot easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.
We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of the telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.
The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera island you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.
【小题1】If a person on Comera island is ill, .
| A．others will phone the doctor in town |
| B．the whistle language will pass the news to the doctor |
| C．his family will take him to the doctor |
| D．people will take him to the hospital |
| A．killed the special ways of speaking |
| B．whistled all the news and opinions |
| C．helped Comera people to communicate |
| D．did not appear on Comera island yet |
| A．it attracts visitors every year |
| B．no visitors have ever been there |
| C．people there have special ears to hear whistles |
| D．people there use the whistle language to communicate with each other |
| A．It is not easy for a person to live on Comera island if he cannot whistle. |
| B．The whistle language can only be found on Comera island. |
| C．The whistle language has been used for hundreds of years on the island, but will not be used any longer. |
| D．The record shows that one best whistler can be heard by others seven miles away. |

Air pollution is a leading cause of cancer and classified among Group 1,or top, human carcinogens (致癌物质), said the International Agency for Research on Cancer (IARC), which is the World Health Organization's (WHO) cancer agency, on Oct 17,2013.
The most widely used system for classifying carcinogens comes from the IARC, which places them into five groups. Group 1 carcinogens definitely cause cancer in humans. Group 2A is probably carcinogenic to humans, Group 2B is possibly carcinogenic, the carcinogenicity of Group 3 in humans is unclassifiable, and Group 4 is probably not carcinogenic to humans. Only a little more than 100 are classified as Group 1 cancer-causing substances, including ultraviolet radiation and tobacco smoke.
“Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants,” the lARC's Dana Loomis said in a statement. “The results from the reviewed studies point in the same direction: the risk of developing lung cancer is significantly increased in people exposed to air pollution.”
In 2010, lung cancer resulting from air pollution killed 223,000 people worldwide, and there was also convincing evidence that it increases the risk of bladder (膀腕) cancer, according to the IARC.
Air pollution is already known to raise risks for a wide range of illnesses, including respiratory and heart diseases.
Air pollution is global, although the levels of it vary over space and time.
Loomis said people in Asia, eastern North America, some places in Central America and Mexico, as well as North Africa have relatively high exposure. Developing countries with large populations and booming manufacturing sectors, such as China, are particularly at risk.
Many cities in China, such as Beijing, frequently see smog. This week, Harbin, the capital city of Heilongjiang province, became the first Chinese city to officially suspend classes due to serious smog
Many developed countries face similar problems, although to a lesser degree than most developing nations. In Europe, levels of many pollutants have fallen. But between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5—tiny particles with a diameter of less than 2.5 micrometers—that are higher than the WHO safety limits, says a report published by the European Environment Agency on Oct 15.
Although both the composition and levels of air pollution can vary dramatically from one location to the other, the 1ARC said its conclusions apply to all regions of the world.
“Given the scale of the exposure affecting people worldwide, this report should send a strong signal to the international community to take action without further delay,” said Christopher Wild, director of the IARC.
【小题1】What might be the best title of the passage?
| A．Signals of air pollution |
| B．Safety limits of air pollution |
| C．Air pollution, cancer risk |
| D．Air pollution, smog risk |
| A．To focus on cancer-causing substances. |
| B．To evaluate the air quality. |
| C．To study the developing risk of cancer. |
| D．To send signals to the international community. |
| A．The composition and levels of air pollution vary from place to place. |
| B．More and more people in developing countries are exposed to air pollution. |
| C．Developed countries face air pollution, the level of which is higher than the safety limits. |
| D．A large number of people worldwide are exposed to air pollution. |

Car crashes are the top killer of American teenagers．Most of the crashes result from distracted driving not paying attention to the road．
Ryan Didone was a fifteen-year-old passenger in a car that hit a tree．He was one of the nation's more than thirty thousand victims of traffic crashes in 2008．Nearly four thousand deaths, about twelve percent, involved drivers aged fifteen to twenty．Ryan's father, Thomas Didone, is a police captain in Montgomery County, Maryland．He said, "It was an inexperienced, immature driver who felt that he was invincible(不可战胜的), driving at night with a carload of kids．He was distracted, he was going too fast, and it ended up causing one death and some upsetting experiences and tragedy for the rest of the community."
Jim Jennings from the Allstate Insurance Company said "The number one cause of distracted-driving accidents is the mobile phone．Talking on the phone or reaching for it is like drinking four beers and driving．If you're texting while driving, you are twenty-three times more likely to get into an accident than somebody who isn't．
Reaching for a cell phone when it's going off, you're nine times more likely to get into an accident than normally driving," The insurance industry recently held a safety event near Washington for teen drivers．
At first, nineteen-year-old Kevin Schumann easily avoided large, inflatable dolls thrown in front of the car to represent children．He also avoided orange cones representing the edge of the road．Then, as part of the test, he started texting. He hit several cones and at least one doll．
Debbie Pickford from the Allstate Insurance Company said, "Teens are especially at risk from distracted driving—and not just because they lack experience on the roads．What we know from research on teen brain development, is that teens don't really have fully developed brains until they are twenty-five years old. You put those two things together and you get a much, much higher risk.”

As a nation we are becoming more aware of the food we and our children are eating.The recent campaign to improve school dinners by celebrity(名人) chef Jamie Oliver has helped raise awareness of our fast food lifestyles.While we may be trying to eat more healthily，it seems we still have some bad habits.
?Healthy eaters or just trendy?
Are there certain things that you do and don’t eat and why？With so many food programmes and books telling you what you should and shouldn’t eat to be healthy，it’s hard to make choices.
Some people are vegetarians for moral reasons，some don’t like the taste of meat and there are one or two people who do it because it’s trendy.Likewise，it can be trendy to follow the latest celebrity’s diet because it’s what the famous are doing.

People are eating out more often now，not just on special occasions as in the past.The choice of restaurants has also diversified.Italian，Chinese and Indian restaurants have been around for years but have now been joined by Mongolian，Japanese，Mexican and so on.Bars and pubs are still popular for food and often promote English cuisine made with local produce.
“We enjoy eating out a couple of times every month whether with friends or just as a couple.We like trying new things so we go to different restaurants.” said Craig,25，County Durham.
?Eating on the go
From chocolate bars to sandwiches more people are eating on the go—on the street，in cars or on buses and trains.While our parents and grandparents may frown at this behaviour，considering it to be bad manners，people eat on the go because they are rushing from one place to another.And in the home the number of people sitting down at a dining table for their evening meal is on the decrease as meal times become more informal.
“If I’m running late for work I don’t think twice about eating toast in the car or on the bus but I know my mum wouldn’t approve，” said Stacey,24.

Everyone has got two personalities—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control your behavior, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.
If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to upset people, so you never express your real feelings. You're quite shy and you aren't very confident.
If you sleep on your stomach, you are a rather secretive（不坦率的）person. You worry a lot and you're always easily upset. You're very stubborn（顽固的）, but you aren't very ambitious. You usually live for today not for tomorrow. This means that you enjoy having a good time.
If you sleep curled up（卷曲）, you are probably a very nervous person. You have a low opinion of yourself and so you're often defensive. You're shy and you don't normally like meeting people．You prefer to be on your own. You're easily hurt.
If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You're usually careful. You have a confident personality. You sometimes feel anxious, but you don't often get depressed. You always say what you think even if it annoys people.
