Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people - up to 3 percent of the population - sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families - hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.
小題1:What caused the happening mentioned in the passage during Amanda’s running?
A.She couldn’t breathe in enough air in the race.
B.She didn’t eat anything before the race.
C.She had been running all summer without a rest.
D.She neither drank enough water nor ate enough of the right kind of foods.
小題2:What can we infer from Paragraph 4?
A.There is no need to worry when sweating too much, even in cold weather.
B.Hyperhidrosis may have a bad effect on your health.
C.Doctors have discovered why people get hyperhidrosis.
D.Hyperhidrosis is a serious disease and no treatment can help.
小題3:The purpose of writing this passage is to____________.
A.tell teens the proper ways to take exercise in summer.
B.tell teens not to run in hot summer.
C.tell teens to pay attention to hyperhidrosis in the summer exercise
D.tell teens how to keep healthy.

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.
?Eating out
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.
小題1:What can we infer from the text?
A.Our parents think highly of the eating habits mentioned in the text.
B.We should get rid of the bad habits and try to be healthier.
C.Japanese restaurants have been around for years.
D.It’s good for people to eat out more frequently.
小題2:People find it difficult to decide what to eat to keep healthy because ________.
A.different programmes and books have different ideas about healthy eating
B.there are many celebrities having different diet styles
C.what the famous are doing is different from ours
D.they have some bad eating habits
小題3:The underlined word “diversified” in Paragraph 4 probably means “________”.
A.made a great change
B.made a big difference
C.had a rapid increase
D.had a wide variety
小題4:Craig often goes to different restaurants because ________.
A.he likes trying new things
B.he follows the latest celebrity diet
C.he enjoys the meal with his friends
D.he has more special occasions to celebrate

Children and teenagers who spend lots of time in front of screens---especially TVs---are   easier to get more weight as they grow, according to a new study.
The findings agree with the research suggesting all that inactive sitting and always watching   advertisements may lead to poor eating habits.
Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the   study, 17 percent were overweight or obese(肥胖的). Twenty-four percent of the 3,500 boys   were also above a healthy weight.
The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games.
From one survey to the next, each one-hour increase in children’s daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI)(體質(zhì)指數(shù)), which measures weight in connection with height. There’s an increase of about half a pound in weight per extra hour of TV.
“The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,” says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston.
“It's important for parents to know that all the obesity-causing(引起肥胖的)screens really should be limited in their children's lives.” Falbe says. “When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink.” What's more, she says, “they can get into a hibernating(冬眠) state on the sofa, even if children are sitting down while playing a computer game.”
小題1:Which of the following statements can be the best title for the text?
A.A new study on screens.
B.TVs do harm to children.
C.The less TV time, the fatter.
D.Too much screen time leads to obesity.
小題2: How many children took part in the study?
A.4,300B.3,500
C.7,800D.9,800
小題3:According to the study, one extra hour screen time will cause children about ______ pound
fatter.
A.0.1B.0.5
C.0.3D.0.7
小題4:According to Falbe , what should parents do to stop children getting fat?
A.Limiting the time of children watching TV.
B.Buying children food advertised on TV.
C.Not allowing children to watch TV.
D.Encouraging children to play computer games.

Losing weight comes with a lot of health benefits—including making your brain sharper.
Yes, it turns out that overweight may damage cognitive functions (認(rèn)知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
小題1:There is less research on overweight and cognitive functions because researchers _____.
A.believe overweight only affects our body
B.have focused on ways to sharpen people’s mind
C.do not consider overweight a main cause for low cognitive ability
D.a(chǎn)re clear about the relation between weight and mental functions
小題2:The result of Gunstad’s study shows that ______.
A.losing weight has little effect on people’s memory
B.losing weight can improve people’s mental functions
C.overweight people are likely to have psychology problems
D.overweight people’s abilities of concentration differ greatly
小題3:What is Gunstad planning to prove next in his research?
A.Slim people are smarter than overweight people.
B.Healthy diet is better than exercise in losing weight.
C.Traditional ways of losing weight are better than operation.
D.Overweight people will get smarter by taking more exercise.
小題4:Which of the following is the best title for th e text?
A.Body Weight and Health
B.Losing Weight by Operation
C.Ways to Improve Mental Functions

Drinking eight cups or two litres of water a day is longstanding advice. But is there any scientific basis for it, asks Dr Chris van Tulleken.
You know those ads that remind us that even a small drop in hydration(水合作用) levels can massively affect performance so you need to keep hydrated with whatever brand of super drink they're selling?
They seem pretty scientific don't they? Man in white coat, athlete with electrodes attached and so on. And it's not a hard sell because drinking feels right - you're hot and sweating so surely replacing that fluid must be beneficial.
Well earlier this year sports scientists in Australia did an extraordinary experiment that had never been done before.This group wanted to find out what happened to performance after dehydration. So they took a group of cyclists and exercised them until they lost 3% of their total body weight in sweat.
Then their performance was assessed after rehydration with either 1) nothing, 2) enough water to bring them back to 2% dehydration or 3) after full rehydration.
So far nothing unusual, but the difference between this and almost every other study that's ever been done on hydration was that the cyclists were blind to how much water they got. The fluid was given intravenously without them knowing the volume.
This is vital because we all, and especially athletes, have such an intimate(密切的)psychological relationship with water consumption.
Remarkably, there was no performance difference between those that were fully rehydrated and those that got nothing. This study was part of a growing movement to "drink to thirst" which hopes to persuade athletes not to over hydrate with the potentially fatal consequence of diluting your sodium level, causing hyponatraemia.
Perhaps the result shouldn't be so surprising. Humans evolved doing intense exercise in extreme heat and dryness. We are able to tolerate losses in water relatively well whereas even slight over hydration can be far more dangerous. In simple terms, being too watery is as bad for you as being too concentrated.
小題1:What’s the main idea of the passage?
A.There is no scientific basis for drinking eight cups of water a day
B.People used to drink eight cups of water a day
C.An experiment about whether people should drink eight cups of water.
D.People shouldn’t believe longstanding advice.
小題2:what does the word“dehydration ”in paragragh 4 mean?
A.doing exerciseB.losing water
C.drinking waterD.having a rest
小題3:What is NOT TRUE according to the passage?
A.Drinking too much water is bad for us
B.Sports scientists in Australia did an extraordinary experiment for the first time.
C.Those that were fully rehydrated and those that got nothing performed differently.
D.The cyclists didn’t know how much water they got.

Country-dwellers(農(nóng)村居民) often say the constant noise, heavy traffic and crowds of the city would drive them mad. Well, they might be right, according to the latest research. City residents are more likely to develop mental illnesses than those who live in villages, a study has found.
Researchers from Cardiff university examined the lifestyles of more than 200,000 people in Sweden and found that those who lived in urban areas were more at risk from mental illnesses than people who lived in villages.
The experts don’t know exactly why this is but they suggest that town and city residents are more likely to be ostracized(排擠) by those around them. They are more likely to experience discrimination(歧視) if they do not fit in, which can lead to them feeling anxious and even developing mental illnesses.
Dr Stanley Zammit, who led the research said that people living in towns and cities are more likely to develop other mental illnesses that result in personality changes — a condition known as non-affective psychosis(非情感性精神病).
Earlier this year an official report found that village-dwellers live an average of two years longer than those living in towns and cities. According to figures from the Office of National Statistics in the UK, men who live in villages are likely to live for between 78 and 79 years, while those in towns and cities can expect to survive to an age of 76. Women on average survive to their 81st birthday in towns and cities, but live to between 82 and 83 in villages. The small marked town of Wimborne Minster in rural Dorset was named the healthiest place to live in.
小題1:What is the passage mainly about?
A.Country-dwellers are more likely to develop mental illnesses.
B.City-dwellers are more likely to develop mental illnesses.
C.Country-dwellers live longer than city-dwellers.
D.City-dwellers live longer than country-dwellers.
小題2:The research from Cardiff University was based on the people’s _________.
A.interests.B.characters.C.occupations.D.lifestyles.
小題3:It can be inferred that  ___________.
A.people like living in towns and cities
B.city-dwellers enjoy their peaceful city life
C.village-dwellers are more likely to be looked down upon by others
D.village-dwellers get along better with their neighbors than city-dwellers.
小題4:Non-affective psychosis is a kind of mental illnesses that is linked to ________
A.character change B.temperature rise
C.pressure increaseD.energy weakening
小題5:We can learn from the last paragraph that generally ________ .
A.women living in villages live the longest

Healthy people with stressful jobs who work long hours but get little satisfaction from what they do have twice the risk of dying from heart disease as satisfied employees, according to a study. Job stress has been known to cause heart problems in people who already have cardiovascular disease (心血管病). Finnish scientists have now shown that even in healthy people the pressures of work can take their toll. High blood pressure, lack of exercise, smoking and being overweight contribute to heart disease—a leading killer in many industrialized countries.
But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the medical histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role.
Workers who had the highest job-related stress levels at the start of the study were more than twice as likely to die of heart disease, according to the study published in The British Medical Journal. Work stress involves too much work as well as a lack of satisfaction and feeling undervalued and unappreciated. Many people work long hours but if the effort is rewarding the stress is minimized.
The British Heart Foundation said the results support earlier research showing that people in jobs with low control, such as manual(體力的) workers, could be as great risk of heart disease than other employees. “ It is advisable for people to try to minimize levels of stress at work and for employees to allow people to have more control at work and to be rewarded for their successes,” the foundation said in a statement.
小題1:Healthy people may die from heart disease of ____________.
A.too much job stress B.working too hardC.feeling valuedD.being satisfied
小題2:Which one of the following is NOT right according to this passage?
A.High blood pressure is likely to cause heart disease.
B.Being overweight may cause heart disease.
C.Job stress is most likely to cause heart disease.
D.Working long hours must cause heart disease.
小題3:The underlined word “minimized” in the third paragraph means “_________”.
A.increasedB.reducedC.raisedD.cured
小題4:The author’s purpose in writing the passage is to _________.
A.a(chǎn)dvise people not to work long hours
B.suggest that everyone be satisfied with everything
C.a(chǎn)sk us to learn to enjoy ourselves
D.tell us that job stress threatens our health nowadays.
