The public commonly associates steroid use with big-time athletics. But the drugs may be even more of a menace to teenagers. The synthetic hormones can stunt a young person’s growth by prematurely closing the ends of the long bones in the skeleton. That means a 1.7 metre, 15-year-old high school student who uses steroids “might get bigger but won’t get any taller”, according to a US doctor.
Nearly seven percent of boys in the US try steroids before the end of high school, according to a 1988 study by professors Charles Yesalis and William Buckley, of Penn State University. The estimate comes from a poll of 3,400 seniors in 46 public and private schools across the US.
“Abusers of Steroids did it to improve their appearance and to excel at sports,” Professor Yesalis said. “Parents, teachers and coaches make boys believe that to be an ideal male you need to have these. Then they say: ‘you can’t play games to have fun; you play games to win.’”
“Such attitudes put many high school athletes at high risk of becoming abusers of steroids,” said Mike Gimbel, director of Baltimore County Office of substance Abuse. “For these athletes, the pressure to perform is incredible,” he said. “It was inevitable that it would seep down to high school level.”
小題1:The word “big-time” in Paragraph 1 most nearly means “________”.
A.long timeB.good timeC.top rankD.modern
小題2:Why are steroids even more of a threat to teenagers?
A.Because they make teenagers grow too tall.
B.Because they make teenagers get too big.
C.Because they prevent teenagers from getting taller and taller.
D.Because they give teenagers too much pressure.
小題3:Which of the following statements is implied but not mentioned?
A.School athletes have too much pressure.
B.Steroids can help people have lots of muscles.
C.The pressure chiefly comes from parents, teachers and coaches.
D.Girls are not interested in steroids.

健康問題一直是生活中的熱點話題。尤其對于女性來說,你知道穿矮高跟鞋和純粹的高跟鞋對你身體健康的影響嗎?
Healthy knees aren't the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos(細高跟鞋).
"It takes a long time to feel the effects of knee osteoarthritis(骨關(guān)節(jié)炎)— and once you do, it is too late," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School's department of physical medicine.
"I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said.”They are better for your feet than stiletto heels, but just as had for your knees.”
The idea that high heels are bad for your health isn't new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained(扭傷)ankles and back problems.
But in 1998, Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage(軟骨)surrounding the knee.
The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.
"This study confirms what we all intuitively(直覺地)know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopedic Surgeons who was not connected to the study.
1. What’s the main idea of the passage?
                                                                           
2. Which sentence in the passage is the closest in meaning to the following one?
In my opinion, it is similar to smoking, for smoking one cigarette does little harm but if you smoke all your life, it’ll be very painful.
                                                                          
3. Please fill in the blank in the passage with proper words or phrases to complete the sentence.(within ten words)

Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situation-for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.
The third kind of loneliness is the most severe. Unlike the second type, chronic (the opposite of “temporary”) usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person’s social contacts, for example, friends, family members, co-workers, etc. we depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease, while temporary and situational loneliness can be a sad, and sometimes dangerous condition.
小題1:How would you treat temporary loneliness according to the passage?     
A.Talk to friends.B.Just ignore it.
C.Go to see a doctor.D.Ask your teachers for guidance.
小題2:“It” in the last sentence of the second paragraph refers to ___________.
A.temporary lonelinessB.situational loneliness
C.a(chǎn) new placeD.sleeplessness
小題3:Why do psychologists want to help chronically lonely people?
A.Chronic loneliness can cause family problems.
B.Chronic loneliness can cause serious illness
C.Chronic loneliness can not be overcome.
D.Chronic loneliness is incurable.
小題4:What is the best title for the passage?

Drinking small amount of hard Japanese rice wine apparently never hurt 114-year-old Kamato Hongo.She is now the world’s oldest living person, according to Guinness World Records.
“Hongo inherited(繼承)the title Monday after the death of the previous record holder, Maud Farris-Luse ,of Coldwater , Mich.,”the record-keeping company said on its website.Farris-Luse was 115 years and 56 days old then.
“Hongo, born on Sept .16,1887, was raised on a farm and counts drinking Japanese rice wine among her favorite things ─ along with black salt, pork ,sashimi(生魚片)and green tea,”according to Guinness. “She also likes traditional Japanese dancing.”
“The key is not storing up stress,”said her 45-year-old grandson Tsuyoshi Kurauchi. “If you do that, you can eat or drink anything.”

Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years.  And indeed,  cutting fat  to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates(碳水化合物) have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates — which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body —— dietary fat is more easily converted to body fat. Therefore, it’s more likely to stay on buttocks, thighs and bellies.? 
But cutting fat from your diet doesn’t necessarily mean your body won’t store fat. For example, between nonfat and regular cookies, there’s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight again. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn’t losing weight. Then he showed his food diary to his coach and revealed he’d been eating half a pound of jelly beans a day. “They don’t have any fat,” he explains. But they had enough sugar to keep him from shedding an ounce. ? 
Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt(酵母乳)that contained exactly the same amount of calories. One group’s yogurt label said “high fat”—the other, “l(fā)ow fat.” The “l(fā)ow fat” yogurt group ate significantly more calories later in the day than the other group. “People think they’ve saved fat and can indulge themselves later in the day with no adverse consequences,” says Richard Mattes, a nutrition researcher at Purdue University. “But when they do that, they don’t compensate very precisely, and they often end up overdoing it.”
小題1:What lessons did the computer programme learn ?
A.Overeating will cause weight gain
B.He can eat half a pound of jellybeans a day
C.He can’t didn’t eat any fat
D.His coach gave him a lecture
小題2:Prof. Barbara’s ecperiement proved that _______________.
A.two groups ate the same amount of calories
B.two groups ate the same wmount of yogurt
C.the “ low fat” yogurt group ate more calories later in the day than the other group
D.people increase the number of calories they eat per day and gain group
小題3:According to the author ,________has less calories.
A.fat
B.protein and carbohydrates
C.low-fat soups
D.sugar
小題4: What can you infer from the text ?
A.To keep from being overweight, people have to eat nofat food
B.The calories from fat just do it a little quicker than from protein and carbohydrates
C.People should avoid temptation
D.Americans realize that it is necessary to count calories before eating the food

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(壽命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遺傳的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.    
小題1:What does "these two killers" in the second paragraph refer to? 
A.gene technology and another treatment of the two diseases.
B.The two murderers who killed the cloned baby
C.The two diseases of cancer and heart disease
D.Hereditary diseases and cancer
小題2: What's the main idea of the third paragraph?
A.How gene technology can be applied in the field of treating hereditary diseases.
B.Gene technology can be used to clone human babies.
C.Gene technology can help people to give birth of a baby.
D.Gene technology can help the English imperial family out
小題3:In what way gene technology can help to treat hereditary diseases?
A.Using gene technology, people with hereditary diseases can have more living days.
B.Using gene technology, scientist finds the wrong gene and corrects it.
C.Using gene technology, human babies can be cloned.
D.Doctors can cure cancer and heart disease with the help of gene technology.
小題4:What is the main purpose of writing this passage?
A.Expressing the writer's idea that gene technology will benefit people
B.Telling people the advantages of gene technology
C.Telling the readers that gene technology will not benefit people
D.Explaining that gene technology will also do harm to the humanity

Zinc(鋅) is one of about 20 elements necessary for good health. It is present in the body in a very small amount but makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.
Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate(硫酸鹽) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.
The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein(蛋白質(zhì)) foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. Food markets should add these elements so that more people could get needed amount of these necessary matters.
小題1:Which of the following statements is true?
A.Scientists found how zinc works a long time ago.
B.People need a large amount of zinc to be healthy.
C.Zinc allows important chemical actions to take place in cells.
D.Zinc must be used in the course of medical operation.
小題2: One of the results from the study of zinc is that _______.
A.there’s only a little zinc in the human body
B.food rich in protein contains more zinc
C.some physical problems are caused by lack of zinc
D.a(chǎn)ny patient who receives zinc sulphate gets well immediately
小題3:The best title for the passage may be _______.
A.A New Discovery B.Zinc and Health

Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being weight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts (內(nèi)臟)when you were a baby and the chance that you would become overweight?
Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.
You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.
Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.
So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.
小題1:The “l(fā)ink” in Paragraph 2 refers to the relationship between _______.
A.bacteria and the chance of being overweight
B.obesity and diabetes
C.diets and the chance of being overweight
D.bacteria and exercise
小題2:Which of the following is NOT the function of “good” bacteria?
A.Helping to digest food.
B.Helping to take nutrients from food.
C.Helping to regulate weight.
D.Making a person ill.
小題3:The purpose of writing this passage is to _______.
A.introduce the role of bacteria in children’s weight
B.a(chǎn)nalyze the influence of obesity on kids
C.give advice on how to lose weight quickly
D.explain the function of bacteria in foods

Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?

Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for(滿足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.
小題1: The passage tells us that Charles Darwin    .
A.was a great English scientist
B.a(chǎn)lways liked doing the experiments that others thought difficult
C.thought even the simplest thing was important
D.didn’t get well with others
小題2: The underlined phrase “set aside” most probably means    .
A.throw awayB.store up
C.put to useD.realize
小題3: The author of the passage tries to    .
A.convince us that Charles Darwin, Galileo and Newton are the greatest scientists in the world
B.draw the conclusion that basic sciences are simple things
C.prove that two sheets of paper, with the same size and shape, will fall at the same speed
D.draw our attention to everyday happenings around us
小題4:Which of the following is TRUE?
A.Darwin really did foolish experiments.
B.According to some people Darwin did foolish experiments.
C.It is believed by all the people that things could be important though they seemed to be simple.
D.Galileo and Newton worked out ancient Greek physics.
