Eco City Farms(生态城市农场) are becoming more popular in cities and towns around the Unites States.
Eco City Farms in Edmonton, Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a working-class community(社区). People do not have very much money. And they have limited access to fresh food in markets.
Over the past two years, the farm has attracted volunteers from the community like Marcy Clark. She schools her four children at home. On a recent day she brought them to Eco City Farms for a lesson. Her son Alston Clark thinks his experience is very valuable.“I like coming out here,”he says,“You know, you connect with the earth, where your food comes from. You appreciate the food a little bit more.”
Margaret Morgan started Eco City Farms. She thinks of it as a place where people can learn to live healthier lives. “Growing food in a community brings people together,”she continues,“Every piece of what we do here is a demonstration(示范) to show people everything about how to have an eco-friendly community.”she says. From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees, but improving the soil with compost(肥料)made from food waste.
Eco City Farms is an experimental operation. The farm gets its power not from the local electricity networks, but from the sun with solar panels. In winter, the green house use a geothermal(地热)system.
Vegetables can be grown all year. So once a week, all winter long, neighbors like Chris Moss and her three children bike to the farm to pick up a share of the harvest.
“I like eating the vegetables ”say five-year-old Owen Moss.

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】What is the main idea of the passage?
| A．How to detect nuclear radiation. |
| B．How radiation kill a man. |
| C．The mystery about nuclear radiation. |
| D．Serious damage caused by nuclear radiation. |
| A．Nuclear radiation can cause cancer to human beings. |
| B．Nuclear radiation can be safe to human beings if its level is low. |
| C．Nuclear radiation can be detected by human senses. |
| D．Nuclear radiation is just like common radio waves. |
| A．The hurt cells can stay in the body many years and then grow into cancer. |
| B．It can do harm to a person while the victim isn't aware the damage has occurred. |
| C．Nuclear radiation can kill a person very easily. |
| D．Radiation can seldom kill a person immediately. |
| A．die of cancer after many years | B．die immediately |

Now Hear This
What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure to loud music, and both now wear hearing aids as a consequence. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分贝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume.'? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather. "I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "
| Levels of Common Noises Normal conversation 50 — 65 dB Food blender 88 dB Jet plane flying above a person standing outside 103 dB Rock band during a concert 110 — 140 dB |
| A．loud music is a major cause of hearing loss |
| B．famous people tend to have hearing problems |
| C．teenagers should stay away from school bands |
| D．the problem of hearing damage is widely known |
| A．not to be seen | B．to fill with sound |
| C．to become larger in size | D．to make good again |
| A．a list of harmful sounds |
| B．the effect of rock concerts |
| C．the noise levels of familiar sounds |
| D．relationship between daily activities and hearing loss |
| A．When your ears feel warm, your hair cells are dead. |
| B．Drummer Andrew Sather gives good advice. |
| C．Many are taking the risk of losing hearing. |
| D．Doctors know how to cure hearing loss. |

When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.
It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of ‘the sporting spirit’ is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.
Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally – admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.

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. |

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans，”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”
【小题1】How many groups of mice are there finally in all in the experiment?
| A．Four. | B．Five. | C．Six. | D．Seven. |
| A．The biological clock regulates mood in humans. |
| B．People born in winter are at higher risk for physical health disorders. |
| C．Being born in winter has a negative effect on people's mental health. |
| D．The length of light will influence the behavior of the mice. |
| A．ended | B．torn | C．hit | D．divided |
| A．A jobhunter. | B．A student in the university. |

I am wearing a small red ribbon this morning to remind myself and others around me that today is World AIDS Day.
The red ribbon, an international symbol of AIDS awareness, is gaining increasing public recognition as more Chinese, from top leaders to movie stars, wear it today.
Gone were the days when the topic of HIV/AIDS was a public and media taboo(禁忌). Over the past few years, we have watched, read and heard many stories from doctors, volunteers and public health officials at the forefront of HIV/AIDS prevention and treatment.
Quite a few people with HIV/AIDS have come forward to share their experiences on TV or in the media.
The local and central governments have become more forthcoming (be helpful) with their new prevention and treatment programmes, and financial input. The latter rose from less than 1 million yuan (US$ 121,000) in 1986 to a pledge of 800 million yuan (US$98.8 million) in the year of 2006.
The change from silence to public and media campaigns with official promises has been remarkable, especially since China battled through the SARS crisis.
But have we got a full understanding on HIV/AIDS? What do we know about the extent of HIV/AIDS in China?
The figures, ranging from confirmed cases to estimates, remain debated. After all, no more than a year has passed since the policy of free medical tests was make public. Unknown numbers from the high-risk groups drug addicts and people working in sex- related place as well as farmers who once sold blood could still be reluctant to come forward.

If a city wishes to host the Olympics, it must submit a proposal(提交提案) to the IOC. After all proposals have been submitted, the IOC votes. If no city with the fewest votes is eliminated, the voting continues, until a majority winner is determined. Typically the Games are awarded several years in advance, allowing the winning city time to prepare for the Games.
In selecting the site of the Olympic Games, the IOC considers a number of factors, and chiefly among them is which organizing committee seems most likely to stage the Games effectively. The IOC also considers which parts of the world have not yet hosted the Games. For instance, Tokyo, the host of the 1964 Summer Games, and Beijing, that of the 2008 Games, were chosen in part to popularize the Olympic movement in Asia. Because of growing importance television worldwide, the IOC in recent years has also taken into account the host city’s time zone. Whenever the Games take place in the USA or Canada, for example, American television networks are willing to pay specially higher amounts for television rights because they can broadcast popular events live in the best viewing hours.
Once the Games have been awarded, it is the duty of the local organizing committee----not the IOC or the NOC of the host city’s country to provide them with money. This is often done with a part of the Olympic television revenues(收入), and corporate sponsorships(社团赞助), tickets sales, and other smaller revenue sources. In many cases there is also direct government support. Although many cities have achieved amounts of money by hosting the Games, the Olympics can be financially risky. When the financial gains from the Games were less than expected, the city was left with large debts.
【小题1】_______will be determined to host the Olympic Games by the IOC.
A. A city that submits a proposal B. A majority winner in voting
C. A city that has perfect time zone D. One that hasn’t hosted the Games
【小题2】 Which of the following words can be used to replace the word “ selecting” in paragraph 2?
| A．electing | B．hoping | C．choosing | D．thinking |
| A．can’t broadcast popular events live in the best viewing hours |
| B．will be forbidden to broadcast live sporting events |
| C．are willing to pay much higher amounts for television rights |
| D．will not pay for the Canadian television networks |
| A．The host city must be left with large debts |
| B．The city may achieve a lot of money |
| C．There is no financial risk in hosting the Olympic Games |
| D．It is impossible that the host city couldn’t make money |
| A．How to host Olympic Games | B．Winner or loser |
