Fear can be fun. Many young people queue up to ride very fast and scary roller coasters, screaming but enjoying themselves. Other people like to read “goose bumps (雞皮疙瘩)” books or watch horror movies at night, scared to death but feeling excited. Why do people like being scared?
　　Fear is an ancient way of surviving. Being scared makes animals, including humans escape from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. Those who lacked a strong fear response were more likely to be killed, leaving the more fearful and careful to pass their genes onto the next generation.
　　How do scientists explain why shaking over such scary things is fun? “Some kids will go to a scary movie and love it and laugh over it, others will feel anxious and hide their faces and some won’t even set foot in the cinema,” said Ned Kalin, a US scientist. “Which kind of person you are depends partly on experiences you’ve had and partly on your genes.”
　　What happens in the brain when something frightens you? Nerves that begin at the eyes and ears lead to a part of the brain called the amygdale. When you suddenly see a snake, for example, the amygdale makes you freeze, sweat, have a quickened heartbeat, or run very fast. However, seeing the snake also uses another part of the brain, the cortex. It analyzes the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. Think of the amygdale as the engine and the cortex as the brake.
　　Back to the first question: Why do some people like to make themselves scared? “One reason is that we can play games with fear, find ways to reduce the scariness by looking away or thinking of something else,” Kalin said. “To believe we have control over a situation gives us a feeling of power.” “Scary movies or novels are good practice to prepare young people for the real thing. Thrills such as roller coaster rides also go to the brain’s pleasure centre.”
　　And there might be some evolutionary advantage to being able to adjust this system that is there to protect people.
　　72. How many questions are answered in the passage?
　　A. 2. 　　　B. 3. 　　　C. 4.　　　 D. 5.
　　73. Some people like to be scared because______.
　　A. they are afraid that the fear genes will be passed onto their children
　　B. it’s a good practice to get prepared for the real frightening situation
　　C. it can help them show their own personalities
　　D. they will feel powerful after getting rid of fear
　　74. Which of the following is true about the people who are not easily scared?
　　A. Their cortex is better at analyzing the situations.
　　B. They are more likely to suffer from potential danger.
　　C. They are born unaffected by anything horrible.
　　D. They lack a strong response towards threat.
　　75. What is the best title of the passage?
　　A. Ready to scream? 　　　　B. How to be scared?
　　C. Willing to shake?　　　　D. Why to be scared?
72.B;73.D;74.B;75; A

　　72．選B。作者先后回答了一下這三個(gè)問(wèn)題：Why do people like being scared?/ How do scientists explain why shaking over such scary things is fun?/ What happens in the brain when　　　　something frightens you?
　　73．選D。從原文第五段To believe we have control over a situation gives us a feeling of　　　　power可知D正確。
　　74．選B。A選項(xiàng)所提的遺傳問(wèn)題在文章第二段“l(fā)eaving the more fearful and careful to pass　　　　their genes onto the next generation.”是用來(lái)解釋“Fear is an ancient way of surviving.” 與A選項(xiàng)表述完全無(wú)關(guān)。原文第五段提到“Scary movies or novels are good practice to prepare young people for the real thing.”這里的good practice值得是看恐怖電影和讀恐怕小說(shuō)；而B(niǎo)選項(xiàng)中所說(shuō)的good practice指的是 “to get prepared for the real frightening situation”；二者完全不同。C選項(xiàng)內(nèi)容文章沒(méi)有涉及。
　　75．選A。從文章中“Fear can be fun”，“screaming but enjoying themselves”，“l(fā)ike to 　　　read “goose bumps” books… but feeling excited ”，“shaking over such scary things is fun”等文字中可以看出文章時(shí)圍繞著恐懼帶給人們刺激與興奮而言的。Scream一詞指（因恐懼﹑痛苦或興奮）尖聲喊叫；而shake則（指人）發(fā)抖, 打顫；脫離了文章的語(yǔ)境，willing to shake不能表達(dá)文章的核心內(nèi)容；而B(niǎo)、D則與文章中心不符。

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?
A．Three kinds of lonelinessB．Loneliness and disease

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

In some urban centers, workaholism is so common that people do not consider it unusual:
They accept the lifestyle as normal. Government workers in Washington D.C, for example, frequently work sixty to seventy hours a week. They don’t do this because they have to; they do it because they want   to.
Workaholism can be a serious problem. Because true workaholics would rather work than do anything else, they probably don’t know how to relax.
Is workaholism always dangerous? Perhaps not. There are, certainly, people who work well under stress. Some studies show that many workaholies have great energy and interest in life. Their work is so pleasurable that they are actually very happy. For most workaholics, work and entertainment keep them busy and creative.
Why do workaholics enjoy their jobs so much? There are several advantages to work. Of course, it provides people with paychecks, and this is important. But it offers more than financial security. It provides people with self?confidence; they have a feeling of satisfaction when they’re produced a challenging piece of work and are able to say,“I made that.” Psychologists claim that work gives people an identity through participation in work, they get a sense of self and individualism. In addition, most jobs provide people with a socially acceptable way to meet others. Perhaps some people are compulsive about their work, but their addiction seems to be a safe-even an advantageous-one.

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.                             
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.                                               
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.                                                              
66. People are finding less and less time for relaxing themselves because_____.                                                 
A. they do not know how to enjoy themselves                                       
B. they do not believe that relaxation is important for health      C. they are travelling fast all the time                                                    
D. they are becoming busier with their work  
67. According to the writer, the most important character for a good manager is his ________.   
A. not fearing stress                                                B. knowing the art of relaxation         
C. high sense of responsibility                                  D. having control over performance   
68. Which of the following statements is true?  
A. We can find some ways to avoid stress. 
B. Stress is always harmful to people. 
C. It is easy to change the habit of keeping oneself busy with work.  
D. Different people can withstand different amounts of stress.  
69. In Paragraph 3, "such a reaction" refers back to_______. 
A. "making a choice between 'flight' or 'fight'"                                                         
B. "reaction to stress both chemically and physically"                                                     
C. "responding to crises quickly"
D. "losing heart at the signs difficulties" 
70. In the last sentence of the passage, "do so " refers to ______.     
A. "expose ourselves to stress"                              
B. "find ways to deal with stress" 
C. "remove stress from our lives"                   
D. "established links between diseases and stress"

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.

When I was a kid, my Mom liked to make breakfast food for dinner every now and then. And I remember one night in particular when she had made breakfast after a long, hard day at hospital.
On that evening so long ago, my Mom placed a plate of eggs, sausage and extremely burned toast in front of my dad. I remember waiting to see if anyone noticed! Yet all my dad did was reach for his toast, smile at my Mom and ask me how my day was at school. I don't remember what I told him that night, but I do remember watching him spread butter and jelly on that toast and eat every bite!
　When I got up from the table that evening, I remember hearing my Mom apologize to my dad for burning the toast. And I'll never forget what he said: "Honey, I love burned toast."
Later that night, I went to kiss Daddy good night and I asked him if he really liked his toast burned. He took me in his arms and said, "Your Momma put in a hard day at work today and she's really tired. And besides – a little burned toast never hurt anyone!"
You know, life is full of imperfect things and imperfect people. What I’ve learned over the years is that learning to accept each other’s faults is one of the most important keys to creating a healthy, growing, and lasting relationship. This good quality is the base of any relationship --- husband-wife or parent-child or friendship! As far as I’m concerned, I’m not the best engineer as expected. However, I have made my efforts. That’s enough.
So learn to take the good, the bad, and the ugly parts of your life. Burnt toast isn’t a deal-breaker! Don’t put the key to your happiness in someone else’s pocket but into your own.
小題1:When his mother put the burnt biscuit on the table, the author _____.
A．wanted to see how his father reacted
