What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure(暴露，接觸) to loud music, and both now wear hearing aids（助聽(tīng)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（暫時(shí)） 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（細(xì)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 (分貝) 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

You’re sitting on the train home and the person opposite you yawns(打哈欠). Suddenly, you’re yawning with him, though you’re not tired.
This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的) yawning, which showed that humans communicate regularly with out words.
Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we’re feeling. “Emotions are closely linked with states of internal(內(nèi)部的) responses,” he explained. “ There are also more visible changes in our gestures and facial expression. When we’re in a group, these signals can spread to another person. For example, there’s the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure.
Hugo Critchley further explained, “Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note of how you’re sitting— it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(微妙的) but clear signals that show emotions.”
So, what lessons can we learn from this? “ Spend time with happy people— otherwise your health could suffer,” said Critchley.” When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.”
小題1: According to Hugo Critchley, ________.
A．emotions are as visible as facial expressions
B．we yawn more frequently when we have a cold
C．emotions are connected with states of internal responses
D．the change of blood pressure is not linked with the change of emotions.
小題2:The underlined word “synchronies” in Paragraph 4 means “_____”.
A．move slowlyB．change rapidlyC．relax temporarilyD．respond accordingly
小題3:From the passage we can learn ________.
A．sadness is as contagious as happiness
B．a(chǎn)nger is less contagious than friendliness
C．surprise is more contagious than smile
D．surprise is the most contagious among emotions
小題4:Which of the following statements is true according to the passage?
A．Emotions have delicate influence on fellow humans.
B．Children like copying the actions of the fellow humans.
C．Scientists are still confused about contagious yawning
D．People tend to communicate more with body language.

Although considered an excellent exercise, jumping rope has never received widespread acceptance because of two reasons. First, most people recognize jumping rope as an excellent form of cardiovascular(心血管的)exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes in order to achieve a beneficial physical effect. Second, many regard it as somewhat boring and overly repetitive(重復(fù)乏味的)—not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun as long as you find a proper way to practise it. Instead of doing the usual two-foot bounce(跳)over and over again, players good at rope-jumping often change their pattern every 10 or 20 jumps: a single bounce, a double-bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping.
Nowadays researchers are discovering that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres(半球)to perform equally to each other.
In short, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life.
小題1: One reason that can explain why rope-jumping has not spread widely is that
　　　.
A．it benefits the cardiovascular system
B．it is too difficult for people to learn to jump
C．it is believed to be boring and repetitive
D．it requires little equipment, time and space
小題2: The first sentence in Paragraph 2 means that　　　in rope-jumping.
A．there is only one proper way to follow
B．the usual way should not be used again
C．the easiest way is always the best one
D．there are different kinds of ways to follow
小題3:According to the researchers, jumping rope　　　.
A．only prepares the brain for learning
B．is suitable for students only
C．helps both brain hemispheres work together
D．can be dangerous for old people
小題4:What does the writer think of rope-jumping?
A．He is strongly against it.
B．He is for it.
C．The passage doesn’t mention it.
D．He knows little about it.

Eight in 10 Americans eat fast food at least once a month and half eat it every week according, to a Gallup Poll. Yet most people who eat fast food know it’s bad for them. So why do they keep eating it?
The answer is simple: the benefits of eating fast food outweigh the long-term implications for most people. However, once you read these reasons why all those trips to the drive through may be slowly killing you, you may just want to stop eating fast food after all.
1. Fast food makes you fat.
A 15-year study of over 3,000 people found that eating fast food is linked to weight gain and insulin resistance. In others words, fast food makes you fat and increases your risk of type 2 diabetes. You probably know this already. But here’s something you may not know.
2. Fast food is addictive.
The more you eat fast food, the more you crave it. One study found that fast food is “a potentially addictive substance that is most likely to create dependence in vulnerable populations.” If you eat fast food once a week or more, you may be addicted to it.
3. Fast food is affecting your kids.
According to the CDC, childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years. Kids have an amazing ability to recall ads they’ve seen. Fast food marketers know this, and design ads accordingly. Research shows strong associations between increases in advertising for non-nutritious foods and rates of childhood obesity.
4. Fast food “burgers” don’t have much burger in them.
One study found that most fast food burgers are composed of about 50 percent water and the actual meat content is only 2.1 to 14.8 percent. So what makes up the rest of it, you ask? Chemical fillers and preservatives, mostly. That’s why we see read horror stories about burgers that don’t go bad.
5. Even “healthy” fast food isn’t that healthy.
Fast food restaurants are catering to consumer demands to produce healthier options. The problem is, their definition of “healthy” is quite lax. One of the healthiest dishes at Burger King, the Garden Fresh Salad Chicken Caesar with TENDERGRILL Chicken and dressing, still has almost 500 calories and 28 grams of fat, and nearly a day’s worth of sodium.
6. Fast food is inhumane to animals.
Okay, this one may not be a reason why fast is killing you, but it’s still a compelling reason to stop eating fast food. 9 billion animals were slaughtered in the US alone in 2012 and much of that meat is for your fast food burgers and chicken sandwiches. Large factory farms resemble more of a “business” than a “farm.” Animals suffer in crowded spaces where they rarely have access to the outdoors or sunlight. They are pumped full of antibiotics to combat disease, which runs rampant in these conditions. Livestock is one of the biggest sources of pollution and environmental negligence, according to the UN.
7. Fast food sodas are loaded with sugar.
High fructose corn syrup (HFCS) is the cheap sweetener most fast food restaurants use in their sodas, desserts, and many other products. Princeton University researchers linked HFCS consumption to obesity in an animal study. Rats given HFCS gained more weight and body fat than those given table sugar.
小題1:How many factors are mentioned which can account for the reason why fast food is slowly killing you?
A．Seven.B．Three.C．Four.D．Five.
小題2:According to the text, we know that_____.
A．many people keep eating fast food because they know nothing about the harm which fast food will bring them
B．fast food plays a key role in children’s growth
C．eating fast food is connected to weight gain and insulin resistance.
D．many fast food restaurants are can offer a good and healthy meal to consumer
小題3:What is the purpose of the passage?
A．To help us make right decisionsB．To advise us to stop eating fast food
C．To tell us how to keep fitD．To encourage us to be humane to animals

    Feel tired lately?Has a doctor said he can’t find anything wrong with you?Perhaps he sends you to a hospital,but all the advanced equipment there shows there is nothing wrong with you.
Then,consider this:you might be in a state of sub-health(亞健康).
Sub-health,also called the third state or gray state,is explained as borderline state between health and disease.
According to the investigation by the National Organization,over 45 percent of sub-health people are middle-aged or elderly.The percentage is even higher among people who work in management positions as well as students around exam-week.
Symptoms(征兆)include a lack of energy,depression,slow reactions,insomnia(失眠),agitation, and poor memory.Other symptoms include shortness of breath,sweating and aching in the waist and legs.
The key to preventing and recovering from sub-health,according to some medical experts,is to form good living habits, alternate work and rest, exercise regularly,and take part in open air activities.
As for meals,people are advised to eat less salt and sugar.They should also eat more fresh vegetables,fruits,fish because they are rich in nutritional elements—vitamins and trace elements(微量元素)—that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化道).They also say that a balanced diet is very helpful in avoiding sub-health.
小題1:When you are in a state of sub-health,you should ________.
A．stay home and keep silent
B．go to a doctor and buy some medicine

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(蒸發(fā)), 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（霍亂）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.
小題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
小題2:The underlined word “hypothermia” in Paragraph 6 possibly means a serious medical condition caused by_______.
A．lower temperature than normal
B．higher temperature than normal
C．more cases of malnutrition
D．cases of waterborne diseases
小題3:According to the passage, climate change has both positive and negative effects on ______.
A．food supplies and buildings
B．freshwater resources and homes
C．human health and food supplies
D．human health and homes
小題4:The passage is mainly meant to tell us _______.
A．how global warming leads to changes in the climate
B．how climate change affects people worldwide
C．why climate change affects our crop growth
D．why climate change contributes to all bad results

British researchers have found that children’s IQ predicts their probability of becoming vegetarians (素食者) as young adults.
Recent studies suggest that vegetarianism may be associated with lower cholesterol (膽固醇), reduced risk of overweight and heart disease.
“We know from other studies that brighter children tend to behave in a healthier fashion as adults—they’re less likely to smoke, less likely to be overweight，less likely to have high blood pressure and more likely to take exercise.” lead author Catharine Gale said, “This study provides further evidence that people  with a high IQ tend to have a healthier lifestyle.”
In the study, Gale’s team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age.
“Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30.”Gale said. 
The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan, and 33.6 percent said they were vegetarian but also ate fish or chicken.
There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken，the researchers added.
One expert said the findings weren’t the whole answer，however.
“We don’t know the beliefs or attitudes of the parents of the children，nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood.” said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas.
小題1:From the article，we know that ________.
A．brighter children are likely to become vegetarians when they are ten.
B．people with a higher IQ will not be overweight
C．brighter children are likely to have a healthier lifestyle
D．overweight may cause high blood pressure
小題2:What does the underlined word “vegan” in the sixth paragraph mean?
A．Someone who only eats vegetables.
B．Someone who chooses not to eat meat or fish.
C．Someone who likes eating meat and fish.
D．Someone who likes eating vegetables.
小題3:This study left some unanswered questions EXCEPT “________”．
A．Did the vegetarian children grow up in a family with a vegetarian parent?
B．Did the children eat a primarily vegetarian diet at the age of 10?
C．Were meatless meals regularly served in the participants’ families?
D．Did the vegetarian children really have a high IQ?
小題4:The main idea of the passage is that ________.
A．the low IQ children will be unhealthier when they grow up
B．being vegetarians can reduce the risk of overweight and heart disease
C．IQ is important to vegetarians
D．high IQ children are more likely to become vegetarian when they grow up
