There was a sweet smell of incense (香) in the air as the wellmuscled man moved his legs into a position well behind his head.It was something that the human body really should not be able to do.But what else would you expect at the First World Yoga Championships?

What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure(暴露，接触) to loud music, and both now wear hearing aids（助听器） as a result. 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（暂时） 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（细胞） 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 may 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 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 at the risk of losing hearing. |
| D．Doctors know how to deal with hearing loss. |

Climate change could affect food supplies, water resources, human health and homes.
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.
【小题1】With global temperature increased by 1–2 °C, _______.
| A．crops yields could be increased in tropical regions |
| B．food production could rise throughout the world |
| C．chances are that food resources would be threatened overall |
| D．mid-latitude areas are likely to experience positive impacts |
| A．lower temperature than normal |
| B．higher temperature than normal |

Bad teeth can be painful and even be deadly. Infections of the gums(牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉质), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
【小题1】According to the passage，what is the function of fluoride?
| A．Making the surface on teeth much cleaner. |
| B．Protecting gums from being infected. |
| C．Keeping holes on teeth from forming. |
| D．Slowing down bacterial growth and acid production. |
| A．do harm to | B．account for |
| C．contribute to | D．stand for |
| A．To warn us of the deadly infections of gums and teeth. |
| B．To introduce the advantages of fluoridated toothpaste. |
| C．To draw our attention to the dental care of young children. |

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(调查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

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（肥胖）. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract（消化道）, 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 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（过敏原） 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 (新陈代谢) 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 circle in its tracks, people need to consume food and supplements that will neutralize（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】 It can be inferred from Para. 2 that __________.
| A．foods with natural enzymes help people keep fit |
| B．we’d better be cautious about raw and whole foods |
| C．it is essential for people to protect their vital organs |
| D．giving up cooked and refined foods is a new lifestyle |
| A．destroy body’s cells | B．may lead to obesity |
| C．are difficult to digest | D．stop body’s metabolism |
| A．To warn people of the problem of obesity. |
| B．To advocate eating more raw and whole foods. |
| C．To inform people of the harm of processed foods. |
| D．To tell the differences between raw and processed foods. |
| A．Different causes of acid accumulation. |
| B．Correct ways to cook raw foods. |
| C．Suitable types of raw and whole foods. |
| D．Active approaches to avoid acid. |
