●What prevents depression:tea,coffee or hot chocolate?
Women who drink for or more cups of coffee a day are a fifth less likely to become depressed.Drinking two or three cups reduces the risk by 15 percent. This is the result of a study of 51,000 women over ten years, published in the Journal of the American Medicine Association.
One theory is that caffeine reduces the  effect of the chemical adenosine(腺苷) in the brain, which can make us feel sleepy by slowing down nerve cell activity. Some anti-depressants also work by blocking the adenosine receptors. Coffee was found to be far more influential on depression levels than hot chocolate or tea due to the high caffeine content.
●How many eggs can we healthily eat: one a day or two a day?
Neither-eat them freely. We’ve long been warned to stick to two or three eggs a week because of their high cholesterol(膽固醇)content. But according to the Food Standards Agency, there is no recommended limit to how many eggs we can healthily eat, unless you have been told to cut down by your doctor.
There is no evidence that eating eggs raises cholesterol levels, and researchers found that eggs contain less cholesterol than in the past because hens are no longer given bone meal, which was banned in the 1990s after the BSE(瘋牛病) cresis.
Research by the British Egg Council found that a medium egg gives you around 100 mg of cholesterol, a third of the 300mg recommended daily limit.
小題1:What is considered to fight depression best?
A.Tea.B.Chocolate.C.Adenosine.D.Coffee.
小題2:We can infer from the text that     
A.too much caffeine will probably make people sleepy
B.coffee contains less caffeine than tea or hot chocolate
C.one is depressed if his brain chemical adenosine is active
D.tea and hot chocolate have no effect on men’s depression
小題3:What can we learn about eggs from the text?
A.We should stick to two or three eggs a week in general.
B.Eat as many eggs as you like unless your doctor advises you not to.
C.Eggs contain more cholesterol at present than ever before.
D.One egg daily and you’ll get more cholesterol than recommended.

小題1:D
小題2:C
小題3:B

Bad teeth can be painful — and worse. They can even be deadly. Infections (感染)of the gums (牙齦)and the teeth can cause bacteria (細(xì)菌)to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk. For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齒 保健)he needed. He was twelve years old.
Experts at the National Institutes of Health 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 the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child 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 (法瑯質(zhì)), the hard surface on teeth, to help prevent holes from forming.
31.According to the passage, bad teeth can be ____________.
A.painful  B. deadly  C.preventive  D.incurable
32.The writer uses the boy's death as an example to show that   _______?
A. not only adults but the young may suffer from teeth problem
B. babies with bad teeth can easily die
C. the doctors should be responsible for the case
D. the boy was not fed with his breast milk
33. What's the main idea of paragraph 4 and 5?
A. How to develop babies' teeth.           B. Why to protect babies' teeth
C. How to keep babies' teeth clean         D. Why to keep babies' teeth clean
34. The passage tells us that _______.
A. Enamel is most widely used to protect teeth in the world
B. Bad teeth may affect the health of adults and the young
C. Breast milk can cure babies' bad teeth
D. Babies' teeth should be brushed once per day
35.Which of the following can be used as the title of the passage?

Young people looking for a job with good pay, flexible hours and job security should consider working in health care, according to a list of the top 15 best jobs in the US for young people.
Health care is the fastest growing sector of the US economy and nearly half of what are considered the top jobs for young people are in the sector, Forbes.com said.
With a medium annual salary of $33,470, dental assistants topped the ranking, while medical assistants, who earn about $28,860, came in No. 3, followed by physical therapist assistants who make a medium salary of nearly $50,000 and health aides who earn $20,560.
Teachers of self-enrichment courses such as pottery and art, were the only non-health job in the top five.
"Almost every one of these requires physical contact," Laurence Shatkin, the author of the book "150 Best Jobs for Your Skills," told Forbes. com. "You have to show up to do them, so you're not being shipped overseas, and they can't be done by a robot."
Shatkin studied which jobs have the highest concentration of 16 to 24 year olds, pay well and have opportunities for entry level positions. He based the ranking on annual salary and openings and projected growth. Many of the jobs do not require a college degree.
Fitness trainers and aerobics instructors, pharmacy technicians and surgical technologists were also among the top 10 jobs for young people.
Because many of the jobs can be done on a part-time basis, they offer the flexibility for people to continue their education while doing them. Some of the jobs offer career prospects and advancements.
"Young people may not have figured out what their priorities are yet," Shatkin told Forbes.com.   "They may use these jobs to discover what they like and where they fit in."
小題1:From the passage, we know that health care is a sector where people in the USA can ________.

If your recurring(經(jīng)常性的)dreams are worrying you,you can rest assured and needn’t worry.Psychologists say in the vast majority of these cases,this is just the mind’s way of dealing with stress and conflicts,problems and concerns.It’s a good thing.
They call be surprisingly vivid and real,or fragmented and weird.They can be comforting or frightening.Our dreams can tell us a lot about what we are really thinking.Dreams give us an x-ray of our unconsciousness(潛意識(shí)).They tell us,particularly when we are at life’s passages or turning points.
Lisa Oppenheim had the same dream whenever she was about to move to a new home or a new city.It’s always just a feeling of needing to stay safe.Experts say disturbing dreams often occur around major life events.For Lisa,it was moving.For others,it can be marriage or divorce,the death of a loved one or pressure at work.
Doctor Siegel has studied the meaning of dream for nearly 30 years.He believes stressful or upsetting dreams can be a sign of what’s buried deep inside our minds.

But many dreams are scary and horrible.How can we understand these nightmares? Doctor Siegel says they are reflecting especially intense emotion or unresolved conflict.The stronger the emotion in the dream,whether it’s pleasure or fear,the likelier the dream is to be important.
Knowing what your recurring dreams or nightmares mean can be liberating.Some nightmares can be a sign of serious psychological problems,such as post-dramatic stress disorder.If they are extremely disturbing or violent or the cause of severe anxiety,you should see a professional therapist(治療專家).

These days, people are concerned about the growing number of kids who are overweight. The number of overweight kids has increased a lot over the last 30 years. Today, more than 15% of the kids aged 6 to 19 are overweight.
In a recent study in the USA, 1,168 boys and girls were asked about the problem. More than half of them said too many girls were overweight.
What does “Overweight” Mean?
Most people who are overweight have too much body fat. The person who is overweight weighs more than is healthy. Being overweight can lead to health problems, like heart disease. Overweight kids also may feel sad about the way they look. Sometimes they get laughed at by other kids and it is harder for overweight kids to make friends.
Why Are Some Kids Overweight?
When asked why some kids were overweight, many kids said it was because overweight kids didn’t exercise enough or eat right. Others said that kids were overweight because fast food restaurants serve the wrong foods or it’s a problem of genes.
How Are the Kids Trying to Lose Weight?
Plenty of kids said they have tried to lose weight and they have been trying to do the following:
● go on a diet – 17%
● eat healthy and exercise – 64%
● eat out less – 4%
● take medicine – 5%
It’s great that kids are thinking about weight problems and are trying to solve them. It’s like putting together a difficult puzzle. Understanding that there’s a problem is one piece. Understanding what causes kids to be overweight is another. And knowing that eating healthy and exercising are the best ways to fix the problem is a very important piece.

If you haven’t heard or seen anything about Road Rage in the last few months, you’ve probably been avoiding the media. There have been countless stories about this new and scary phenomenon, considered a type of aggressive driving. You have most likely encountered aggressive driving or Road Rage recently if you drive at all.
While drunk driving remains a critical problem, the facts about aggressive driving are surely as disturbing. For instance, according to the National Highway Transportation Safety Association, 41,907 people died on the highway last year. Of those deaths, the agency estimates that about two-thirds were caused at least in part by aggressive driving behavior.
Why is this phenomenon occurring more than ever now, and why is it something that seemed almost nonexistent a few short years ago? Experts have several theories, and all are probably partially correct. One suggestion is sheer overcrowding. In the last decade, the number of cars on the roads has increased by more than 11 percent, and the number of miles driven has increased by 35 percent. However, the number of new road miles has only increased by 1 percent. That means more cars in the same amount of space; and the problem is magnified in urban areas. Also, people have less time and more things to do. With people working and trying to fit extra chores and activities into the day, stress levels have never been higher. Stress creates anxiety, which leads to short tempers. These factors, when combined in certain situations, can spell Road Rage.
You may think you are the last person who would drive aggressively, but you might be surprised. For instance, have you ever yelled out loud at a slower driver, sounded the horn long and hard an another car, or sped up to keep another driver from passing? If you recognize yourself in any of these situations, watch out!
Whether you are getting angry at other drivers, or another driver is visibly upset with you, there are things you can do to avoid any major conflict. If you are easily influenced by Road Rage, the key is to discharge your emotion in a healthy way. If you are the target of another driver’s rage, do everything possible to get away from the other driver safely, including avoiding eye contact and getting out of their way.
小題1:The first sentence in Para. 1 implies that ______.  
A.onemaybeangeredbymediareportsandwantstoavoidthem
B.themediacoinedtheterm“RoadRage”onlyafewmonthsago
C.RoadRagehasreceivedmuchmediacoverageinthelastfewmonths

A.relieveB.causeC.spreadD.prevent
小題3:Which of the following characterizes aggressive driving?
A.Talking while driving.
B.Driving at high speed.
C.Sounding the horn when passing.
D.Shouting at another driver.
小題4:The last paragraph is intended to _________.

The word “sport” first meant something that people did in their free time. Later it often meant hunting wild animals and birds. About a hundred years ago the word was first used for organized games. This is the usual meaning of the word today. People spend a lot of their time playing football, basketball, tennis and many other sports. Such people play because they want to. A few people are paid for the sport they play. These people are called professional sportsmen. They may be sportsmen for only a few years, but during that time the best ones can earn a lot of money. For example, a professional footballer in England earns more than 30,000 dollars a year. The stars earn a lot more. International golf and tennis champions can make more than 500,000 dollars a year. Of course, only a few sportsmen can earn as much money as that.
Perhaps the most surprising thing about sportsmen and money is that the stars can earn more money from advertising than from sports. An advertisement for sports equipment does not simply say “Buy our things”. It says “Buy the same shirt and shoes as …”. Famous sportsmen can even advertise things like watches and food. They allow the companies to use their names or a photograph of them and they are paid for this. Sport is no longer just something for people’s spare time.
小題1:From the passage we can learnt that_______.
A.  people spend too much money on sports
the development of sport is slower than any other activity
most people enjoy sport because they can earn money
nowadays sport is not merely a pastime for people
小題2:Nowadays, the word “sport” means “________” .
A.what people do in their spare timeB.hunting wild animals and birds
C.organized games D.something people are paid to do

 The common cold is the world's most widespread illness, which is a plague that man receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions, explorers have reported being free from colds until coming into contract again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War, soldiers who spent long periods in the trenches, cold and wet, seldom caught colds.
In the Second World War, prisoners at Auschwitz concentration camp, naked and starved, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to relieve the symptoms.
小題1:The writer offered ___ examples to support his argument.
A.4B.5C.6D.3
小題2:Arctic explorers may catch colds when___.
A.they are working in the isolated Arctic regions
B.they are writing reports in terribly cold weather
C.they are free from work in the isolated Arctic regions
D.they are coming into touch again with the outside world
小題3:Volunteers taking part in the experiments in the Common Cold Research Unit___.
A.suffered a lotB.never caught colds
C.often caught coldsD.became very strong
小題4:The passage mainly discusses___.
A.the experiments on the common cold
B.the fallacy about the common cold
C.the reason and the way people catch colds
D.the continued spread of common colds

Britain is set to face an increase in cold winters, with up to one-in-seven hitting the UK with longer periods of time when temperatures are below freezing, a study has suggested.The prediction was based on research that found out how low solar activity affected winter weather patterns.
However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age".The findings appear in the journal Environmental Research Letters."We could get to the point where one-in-seven winters are very cold, as we had at the start of last winter and all through the winter before last," said co-author Mike Lockwood, professor of space environment physics at the University of Reading.
Using the Central England Temperature (CET) record, the world's longest instrumental data series that dates back to 1659, the team said that in general temperatures during recent winters had been obviously lower than the longer-term temperatures."The mean CET for December, January and February for the recent relatively cold winters of 2008 ~ 2009 and 2009~2010 were 3.50℃ and 2.53℃ respectively," they wrote."However, the mean value for the previous 20 winters had been 5.04℃.The series of lower winter temperatures in the UK during the last three years had raised questions about the probability of more similar, or even colder, winters occurring in the future."
Last year.Professor Lockwood and colleagues published a paper that found a link between fewer sunspots and atmospheric conditions that "blocked" warm westerly winds reaching Europe during winter months, opening the way for cold easterly winds from the Arctic and Russia to sweep across the region.Professor Lockwood, while acknowledging that there were a range of possible meteorological factors (氣象因素) that could influence blocking events, said the latest study moved things forward by showing that there was "improvement in the predictive skill" when solar activity was taken into consideration.
小題1:We can know from the second paragraph that _____.
A.research shows that Britain will soon fall into an ice age
B.Mike Lockwood's research focuses on space environment physics
C.it was quite cold in Britain over the entire winter last year
D.so far one-in-seven winters have been very cold in Britain
小題2:The.underlined word "mean" in Paragraph 3 is closest in meaning to "_____".
A.a(chǎn)verageB.stableC.ungenerousD.changeable
小題3:What can we infer from the last paragraph?
A.It was sunspots that blocked warm westerly winds reaching Europe.
B.Meteorological factors hardly have any influence on blocking events.
C.The latest study done by Professor Lockwood was of little practical value.
D.Considering solar activity or not affects the accuracy of weather forecasting.
小題4:What's the best title of the passage?
A.Another big danger approaching the UK
B.Research finds out solar activity is to blame for the cold
C.UK faces more cold winters due to weaker solar activity
D.Changes in weather patterns should be responsible for low solar activity
