A Southampton University team found that people who were vegetarians by 30 had recorded five IQ points higher on average at the age of 10. Researchers said it could explain why people with a higher IQ were healthier as a vegetarian diet was connected to lower heart disease and obesity rates. The study of 8,179 people was reported in the BritishMedicalJournal.
Twenty years after the IQ tests were carried out in 1970, 366 of the participants said they were vegetarians — although more than 100 reported eating either fish or chicken.
Men who were vegetarians had an IQ score of 106, compared with 101 for non-vegetarians; while female vegetarians averaged 104, compared with 99 for non-vegetarians. There was no difference in the IQ scores, between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken.
Researchers said the findings were partly related to better education and higher class, but it remained statistically significant after adjusting for these factors.
Vegetarians were more likely to be female, to be of higher social class and to have higher academic or vocational qualifications than non-vegetarians. However, these differences were not reflected in their annual income, which was similar to that of non-vegetarians.
Lead researcher Catharine Gale said, “The findings that children with greater intelligence are more likely to report being vegetarians as adults, together with the evidence on the potential benefits of a vegetarian diet on heart health, may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk of coronary heart disease in adult life.
But Dr Frankie Phillips of the British Dietetic Association said，“It_ is_ like _the _chicken  _and _egg. Do people become vegetarians because they have a very high IQ or is it just that they are clever enough to be more aware of health issues？”
小題1: What’s the result of the research mentioned in the text?
A．Intelligent children are more likely to become vegetarians later in life.
B．Children with a higher IQ are less likely to have heart disease later in life.
C．Intelligent children tend to belong to higher social class later in life.
D．Children with a healthier heart tend to have a higher IQ later in life.
小題2:It was found in the research that________.

I’m a teacher. But there are days, like today, when I wonder why. The results of an English quiz taken by my fifth-graders were depressing. Despite my best efforts, the world of pronouns remains a mystery to them. How I wish there were a way to make the study of our language as exciting as a computer game, so the glazed (目光呆滯) looks would not appear in their eyes at the mention of the word “grammar.” I remember my husband’s words: “Why don’t you quit? You’d probably make more money by doing something else, and you wouldn’t have papers to grade every night.”
Tonight I have a stack of papers to grade, which I promised my students I would return tomorrow. But a friend, whom I haven’t seen in a year, is visiting from Belgium, and I told her I would keep this evening free.
Sitting in traffic behind a distant stoplight, it’s hard not to replay the day. A voice reports the body of a local youngster, missing for weeks, has been identified.
This missing child has had a deep effect on my students. They wondered, “If it happened to her, could it happen to me?”
My children had found the answer themselves. They got out their pencils, markers and made cards. Cards were written with words of compassion and love for a mother and father they didn’t know. Cards were filled with red hearts, golden crosses, flowers and angels. Their cards, intended to comfort others, comforted the children themselves by leading them past the anxiety, back into the world of security (安全) that should be theirs.
And then I remember why I’m still teaching. It’s the children. They’re more important than a lifetime filled with quiet evenings and more valuable than a pocket filled with money. My classroom, a child-filled world of discovery, of kindness and of caring is the real world.
It’s time to call my friend. I have promises to keep. She’ll understand. After all, she’s a teacher.
小題1:The writer wonders why she is a teacher because _____.
A．her students often play games in class
B．teaching is not a well-paid job
C．her students feel bored with grammar
D．she feels frustrated at teaching
小題2: The students’ attitude to the missing child’s parents might be that of _____.
A．doubtB．unconcern C．sympathy D．tolerance
小題3:What is the most important according to the writer?
A．A pocket filled with money.
B．The kind and caring children.
C．A lifetime filled with quiet evenings.
D．The freedom to control her own time.
小題4:What promise will the writer keep?
A．To grade papers that night.B．To help a student with homework.
C．To accept her husband’s advice.D．To meet her old friend.

When my son, Mark, was in the third grade, he saved all his pocket money for over three months to buy holiday presents. The third Saturday in December Mark said he had made his list and had twenty dollars in his pocket.
I drove him to a nearby supermarket. Mark picked up a hand basket and went in while I waited and watched in the car. It took Mark over 45 minutes to choose his presents. Finally he came to the checkout counter (交款處) and reached into his pocket for his money. It was not there! There was a hole in his pocket, but no money. Mark stood there holding his basket, tears falling down his face.
Then a surprising thing happened. A woman came up to Mark and took him in her arms. "You would help me a lot if you let me pay for you," said the woman. "It would be the most wonderful gift you could give me. I only ask that one day you will pass it on. When you grow up, I  would like you to find someone you can help. When you help others, 1 know you will feel as good about it as I do now."
Mark took the money, dried his tears and ran back to the checkout counter as fast as he could. That year we all enjoyed our gifts almost as much as Mark enjoyed giving them to us.
I would like to say ’"thank you" to that very kind woman, and tell her that four years later, Mark went house to house collecting blankets (毯子) and clothes for the homeless people in the fire. And I want to promise her that Mark will never forget to keep passing it on.

I am a strong believer that if a child is raised with approval, he learns to love himself and will be successful in his own way.
Several weeks ago，I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines．I kept asking him to sit down, telling him that he would concentrate better. He sat but seconds later, as if he didn’t even notice he was doing it, he got up again．I was getting frustrated, but then it hit me．I started noticing his answers were much quicker and accurate when he stood up．Could he be more intent while standing up？
This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet, calm child was a sure way to success．This child would have the discipline to study hard, get good grades and become someone important in life．
Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality traits，and all you can do is loving and accepting them．As parents，throughout their growing years and beyond that, we need to be our kids' best cheerleaders，guiding them and helping them find their way.
I have stopped asking my son to sit down and concentrate．Obviously, he is concentrating just in his own way and not mine．We need to learn to accept our kids' ways of doing things．Some way may have worked for me but doesn't mean we need to carry it through generations．There is nothing sweeter than being individual and unique．It makes us free and happy and that's just the way I want my kids to live their own life．

In many parts of the world，cars play an important role in daily life and many societies would not exist without them. So the idea that in 20 years’ time, no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean much saving，no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself, and it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis，who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together.
Davis says cars will be fitted with some intelligent devices to regulate the distance between one car and another. The car will automatically speed up, or slow down, to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people. By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen. And by 2020, cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the normal amount.” says Davis. “But all the others in the train would bum about ten percent 0f the normal amount, and so produce about ten percent of the pollution.”
小題1: We know from the passage that governments and car manufacturers        .
   A. do not believe the prediction that no one will own cars by 2020
   B. are devoted to the technological revolution in car industry
C. consider the predictions seriously
   D. have put the super-intelligent car into mass production
小題2: Which of the following will be the characteristic of the cars of 2020?
   A. The car will speed up out of control．
   B. We will own as many cars as we want．
C. All cars will be driven by computers．
D. Cars will produce more pollution than present ones．
小題3:The leader of the research team believes that the present car culture will change because        .
A. cars play a very important role in daily life
B. many societies would stop functioning without cars
C. cars should not be owned by one individual
D. it causes many deaths to human society
小題4:The expression closest in meaning to the phrase “in convoy” in the last paragraph is        .
A. in line         B. sidelong
C. side by side     D. shoulder to shoulder
小題5: What will happen if cars are joined to each other electronically in 2020？
A. Motorists will get a clear view of the road．
B. The weather condition will not have effect on motorists．
C. There will be less pollution caused by car．
D. All trains will burn less fuel than present．

Malaria, the world’s most widespread parasitic (寄生蟲引起的)disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can’t) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.        
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn’t kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.  
小題1:According to paragraph 1, many people don’t seek care because ________.
A．they are too poor
B．it is unusual to seek care
C．they can remain unaffected for long
D．there are too many people suffering from the disease
小題2:People suffering from malaria ________.
A．have to kill female mosquitoesB．have ability to defend parasites
C．have their red blood cells infectedD．have sudden fever, followed by chills
小題3:Which of the following may be the reason for the wide spread of the disease?
A．Its resistance to global warming.
B．Its ability to pass on the virus frequently.
C．Its outbreaks in cities with large populations.
D．Its ability to defend itself and resist new drugs.
小題4: It can be inferred from the passage that ________.
A．no drugs have been found to treat the disease
B．the alternative treatment is not easily available to most people
C．malaria has developed its ability to resist parasites
D．nobody knows what will be the drug to treat the disease

Good Genes Mean Long Life
Scientists have discovered that living to the age of 100 may have nothing to do with the lifestyle you lead and everything to do with the type of genes you have.
For the lucky carriers of “Methuselah” genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern (組合).
The “Methuselah” genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare.
The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old.
Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children.
The studies show that tiny mutations (變異) in the make-up of some genes can greatly increase a person’s lifespan (壽命). Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy.
David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread.
“If we know which genes control longevity (長壽) then we can … target them with drugs. That makes it possible to slow down ageing,” he told The Times.
“Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged (義不容辭的) to take it.”
小題1:According to the article, which of the following is the most important if a person is to live to the age of 100?
A．Eating healthy food every day.B．Having the right types of genes.
C．Having a healthy lifestyle.D．Taking drugs that prevent ageing.
小題2:According to the article, the ApoC3 gene is found in ________ of people over 100 years old.
A．10% B．20%C．30% D．50%
小題3:Which of the following statements is TRUE of the research led by Professor Nir Barzilai?
A．The team studied the genes of over 100 people over 100 years of age.
B．The researchers found that mutations in certain genes lead to longer life.
C．The researchers found ways to develop drugs that could cure age-related diseases.
D．The study suggested that most people have genes that could lengthen their lives.
小題4: According to David Gems, ________.
A．drugs to slow ageing will be very expensive
B．modern science will be able to find more longevity genes
C．it is the duty of medical scientists to fight the problems of ageing
D．scientists can make new genes that will allow longer life

Honeybees
Honeybees can do three kinds of jobs.
It is one of the most unusual insects in the world. Bees are special because they divide up their honeybee work. Each bee has a certain job to do.
The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蠟). They store honey there for food. Workers are always cleaning and fixing the hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe.
Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.
The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day.
小題1:The bee’s nest is called a _______.    
A．hive B．honeycomb C．drone D．wax
小題2:Which jobs do workers do?
A．They lay 2, 000 eggs each day and build a nest.
B．They mate with the queen bee and then starve.
C．They clean the hive and keep it cool.
D．They attack the queen bee.
小題3:According to the story, bees _______.  
A．a(chǎn)re very dangerous insects
B．will attack anything or anyone to protect the hive, if necessary
C．a(chǎn)re like any other insect that flies
D．eat each other as food
小題4:The drone is driven away when its job is finished, because _______.  
A．it attacked the workersB．it is no longer needed in the hive

A scientist who developed a way to calculate how much water is used in the production of anything from a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of “virtual water (虛擬水)”, a calculation method that has changed the nature of trade policy and research.
Allan has written seven books and published more than 100 papers.
The Stockholm International Water Institute said this idea is now embedded (埋藏) in the production of foods and industrial products. The institute said Allan’s work had made a big effect on global trade policy and research, especially in water-scarce (缺水的) regions.
“The improved understanding of trade and water management issues on local, regional and global scales are of the highest value for the successful and sustainable (可持續(xù)的) use of water resources,” it said.
“People do not only use water when they drink it or take a shower,” the institute said. “Behind the morning cup of coffee, there are 140 liters of water that was used to grow, produce, package and ship the beans.” That is about as much water as a person in England uses on average for all daily drinking and household needs.
“For a single hamburger, about 2,400 liters of water are needed. In the USA, the average person uses nearly 7,000 liters of virtual water every day.” It said that was more than three times the average use of a Chinese person.
小題1:Allan was awarded the prize because _______.
A．he wrote seven books on trade policy
B．he published more than 100 papers on water management
C．he found a new kind of water in water-scarce areas
D．he came up with the idea of virtual water
小題2:Which of the following is TRUE according to the passage?
A．The average American uses about 7,000 liters of water a day.
B．The average Chinese uses nearly 2,300 liters of virtual water a day.
C．An Englishman usually drinks about 140 liters of coffee a day.
D．A hamburger usually contains about 2,400 liters of water.
小題3:What do we learn about John Anthony Allan from the passage?
A. He won the 2008 Nobel Prize.        B. He has written over 100 books.
C. He works at the University of London.        D. He lives in the USA.
小題4:What effect does the idea of virtual water have?
A．It helps us realize the importance of trade.
B．It helps people do successful business.
C．It helps us make use of water scientifically.
D．It tells us how much water we use a day.
