Cell phones:  is there a cancer link?
Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病學) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ” said Linet. “We don’t have the evidence that there’s much danger. ”
Studies so far suggest a weak connection between EMFs(電磁場) and illness— so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.
小題1:From the passage we can learn that some people are worried because _______.
A.they have evidence that the use of cell phones can lead to cancer
B.they make a fuss over cell phone use
C.some experts have given a warning
D.cell phones are responsible for brain tumors
小題2:By saying “I don’t support warning labels for cell phones, ” Dr Martha Linet has the idea that _______.
A.the worrying is unnecessary
B.cancer-warning labels should be on cell phones
C.there is a link between cell phones and cancer
D.cell phones have nothing to do with cancer

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 “________”.

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.
Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock(家畜).During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.
People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy saving.
House building becomes a great challenge(挑戰(zhàn))to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy saving houses.
小題1:What did people begin to consider as electricity was no longer cheap?
A.The climate of their areas.
B.The energy for their houses.
C.The fashions for their houses.
D.The building materials for their houses.
小題2:People in some areas gain a source of heat by _________.
A.keeping their livestock downstairs
B.protecting their livestock from the cold
C.sharing their houses only with their cows
D.living on the second floor with their livestock
小題3:The underlined words “natural law” in the third paragraph refer to the fact that ________.
A.heat raises the temperature in the houses
B.heat goes in the upward direction
C.heat goes up if temperature is raised
D.heat increases the temperature of rocks
小題4:From the passage, we can conclude that __________.
A.people will no longer consider building materials in the future
B.energy saving buildings will become more popular in the future
C.a(chǎn)lmost all people will move into the houses heated by large rocks
D.energy engineers will devote themselves only to modern technology.

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

Going on holiday not only makes you feel good while you’re there, you also gain the health benefits for months, new research shows.
Jetting off to destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found.The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed.Experts say workers should always take their full holiday entitlement(權利)each year, but as many as one in three don’t.
The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working.The average blood pressure of those on holiday dropped by six percent while the workers saw their blood pressure rise by two percent over the same period.The sleep quality of holidaymakers improved by 17 percent while that of the non-holidaymakers deteriorated by 14 percent.
The study also found the ability of vacationers to recover from stress, known as the stress-resilience test improved by 29 percent.There was a 71 percent fall in stress resilience scores among workers.Tests showed a fall in blood glucose levels, reducing the risk of diabetes (糖尿病), trimmer waistlines and improved mood and energy levels, with the effects sustained for at least two weeks after returning home.
The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK’s largest healthcare charity.
小題1:According to the passage, how many people go on holiday?

People who are cheerful and relaxed are less likely to suffer from colds. It’s possible that being full of vim and vigor helps the body fight illnesses, say the researchers from Carnegie Mellon University (CMU) in Pittsburgh.
“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(癥狀).   
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!
小題1:What is the text mainly about?
A.how to get rid of coldsB.Attitude determines life
C.Smiles turn away colds D.Different opinions about colds
小題2:The word “full of vim and vigor” underlined in Paragraph 1 probably means_______.
A.ignorantB.well-informedC.energeticD.in low spirits
小題3:According to the finding a leading factor of catching colds should be one’s _______.
A.health.B.personality.C.qualityD.mood
小題4:By saying the last paragraph, the writer intends to suggest_______.

A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.
David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (動態(tài)) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
小題1:What is the passage mainly about?
A.Teens’ sleep is linked to their relationship with people around them.
B.Lack of adequate sleep puts teens at risk of many bad consequences.
C.Modern technology has something to do with teens’ sleep problems.
D.It is necessary for teens to join in sports and positive social activities.
小題2:According to Maume’s analysis, who will probably have a poor night’s sleep?
A.Teens who feel like talking with their parents.
B.Teens who have friends sharing their dreams.
C.Teens who feel contented about themselves.
D.Teens who lack a sense of security at school.

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(社團贊助), 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.
小題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
小題2: Which of  the following words can be used to replace the word “ selecting” in   paragraph 2?
A.electingB.hopingC.choosingD.thinking
小題3:If the Games take place in Canada, American television networks___.
A.can’t broadcast popular events live in the best viewing hours
B.will be forbidden to broadcast live sporting events
C.a(chǎn)re willing to pay much higher amounts for television rights
D.will not pay for the Canadian television networks
小題4:According to the last paragraph, which following statement is true?
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
小題5:Which of the following can be the best title of this passage?
A.How to host Olympic GamesB.Winner or loser
C.Applying for host for OlympicsD.The Olympic Games
