举一反三
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.
Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.
小题1:We may learn from Paragraph 1 that_________.
| A．the decline of exercise rates is newly discovered |
| B．the study suggests 31% of female adults get too little exercise |
| C．the good enough data has been collected from only one country |
| D．the industrial revolution has changed the way people live to some degree |
| A．have little time to exercise |
| B．hate to get regular exercise |
| C．take more exercise to lose weight |
| D．exercise more than men in their country |
| A．powerful | B．rich | C．lazy | D．unpopular |
| A．Worldwide Lack of Enough Exercise |
| B．New Health Discovery |
| C．Evolvement of Human Beings |
| D．Benefits of Taking Exercise |
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. |
“We need to take more seriously the possibility that a positive emotional style is a major player in disease risk,” says psychologist Sheldon Cohen, the study’s lead researcher.
In a previous study, Cohen and his colleagues found that people who tended to be cheerful and lively were least likely to develop sniffles, coughs, and other cold symptoms(症状).
Those findings were interesting, but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead, it was still probable that a person’s underlying personality is what matters.
Evidence suggests, for instance, that certain people are naturally more likely to be outgoing and optimistic, with high self-respect and a sense of control over life. This would mean that who we are, not how we feel, finally decides our chances of catching colds.
To figure out which mattered more (personality or emotions), the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. They told the researchers about the positive and negative feelings they had experienced that day.
The results showed that everyone in the study was equally likely to get infected. Their symptoms, however, differed depending on the types of emotions that they had reported over the previous 2 weeks.
Among those who reported good moods and had been infected with the flu virus, for example, 28 percent developed coughs and stuffy(堵塞)noses. On the other hand, those symptoms struck 41 percent of people who had been less positive. Scientists argue about whether negative emotions or positive emotions have a stronger effect on how healthy we are. For now, it can’t hurt to look on the bright side more often than not!
小题1:What is the text mainly about?
| A．how to get rid of colds | B．Attitude determines life |
| C．Smiles turn away colds | D．Different opinions about colds |
| A．ignorant | B．well-informed | C．energetic | D．in low spirits |
| A．health. | B．personality. | C．quality | D．mood |

If greenhouse gas emissions keep increasing at the current rate, global temperature is expected to rise between 2°C and 6°C by 2100. This doesn’t sound much, but a 5°C change is the difference between the current warm period and an ice age.
Global warming leads to other changes in the climate: melting ice, more evaporation(蒸发), changes in geographical patterns of rainfall, heavier downpours separated by longer dry spells, more frequent heat waves, more intense hurricanes, and sea level rise.
These changes could affect crop growth as drought, increased evaporation and shrinking glaciers（冰川）disrupt water supply. Some crops could suffer heat stress. While there may be benefits in some regions, overall climate change is likely to have a negative impact on global food supplies. The impacts of climate change on agriculture will vary widely around the world. A global temperature rise of 1–2 °C is expected to increase food production in some regions, particularly mid-latitude areas. But in tropical regions even a small amount of warming could reduce crop yields. A temperature rise of 3 °C or more could threaten global food resources, as all regions are likely to experience negative impacts overall.
Freshwater resources could also diminish, especially in tropical regions, as rain patterns change and evaporation speeds up. Some communities could lose essential melt water as glaciers disappear, while more intense rainfall and hurricanes could cause more flooding, leading to water pollution and bacterial diseases such as cholera（霍乱）becoming more widespread.
Climate change could lead to a variety of health impacts – both positive and negative. On the negative side, scientists anticipate more cases of malnutrition, heatstroke and waterborne diseases such as cholera. Although some populations will benefit from a reduced risk of cold-related illnesses such as hypothermia, overall a warming world is likely to have negative effects on human health.
Scientists also expect damage to homes and buildings from more intense hurricanes, heavier rainfall and rising sea levels. Climate change is likely to affect infrastructure by increasing the risk of both coastal and inland flooding around the world, owing to a combination of heavier rainfall, rising sea levels and increased storm damage. Homes and buildings could also be affected by the thawing of frozen ground and greater risk of forest fires.
The consequences of climate change will have an impact on people around the world.

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. |
