What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the ba
sic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.
It is exciti
ng to imag
ine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future. According to the passage, human death is now mainly caused by _______.
| A．diseases and aging | B．acci dents and war |

| A．heart disease will be far away from us |
| B．human brains can decide the final death |
| C．the basic materials of cells will last forever |
| D．human organs can be repaired by new medicine |
We can learn from the passage that _____.
| A．human life will not last more than 120 years in the future |
| B．human have to take medicine to build new skin cells now |
| C．much needs to be done before humans can have a longer life |
| D．we have already solved the technical problems in building new cells. |
Have you ever heard the story of the four-minute mile? Many years ago, people believed that it was impossible for a human being to run a mile in less than four minutes until Roger Banister proved it wrong in1954.
What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who does not know how to swim, falls in deep waters? They drown. If an animal who has not learned swimming could escape by swimming, why not you? Because you believe you will drown while the animal does not.
Have you ever wondered why the letters are organized in a particular order on hour keyboard? You might have thought it is to increase the typing speed. Most people never question it. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam if the operator typed too fast.
These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers a direct command to your nervous system.
I used a snake in my workshops for children to show them how unrealistic some of their beliefs are. Students of a school in India, said snakes were slippery, slimy (黏糊糊的) and poisonous. After doing an exercise for changing beliefs, they handled my snake and found it to be dry and clean. They also remembered that only three types of poisonous snakes exist in India.
Did this story end the way you thought? Review your beliefs now and find out which ones you need to change.

What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

learning better at school shows power in your job
the better you are at school subjects, the more helpful they are in your career.
learning each subject well is an ability in many jobs.

Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens(过敏原), prompting researchers to ask: Are cats and dogs really safe for children?
A study finds that, contrary to many parents’ fears, owning cats or dogs does not increase a child’s risk of developing allergies, and in fact, may actually protect them. The study’s lead author, Dr. Dennis Ownby of the Medical College of Georgia, said that even he was “very surprised” by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first years of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps “exercise” their immune（免疫的） systems early in life so that they’re better able to resist allergic diseases later.
“There’s something very important in the first years of life when the immune system is developing that we can retrain it away from an allergic response,” said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child’s allergy risk, they say if a family already has one or more animals, there’s no need to get rid of them.
41. Why do the researchers feel “very surprised” by the results of the study?
A. Because the results are contrary to what they have expected.
B. Because so many families are going to get rid of their cats and dogs.
C. Because parents are so much worried about their children.
D. Because children with animals may develop allergies easily.
42. Compared with children who have pets, those who haven’t ________.
A. will lose the chance to develop immune system
B. may suffer allergic diseases more often
C. will reduce the harm from bacteria
D. are more likely to resist allergic diseases
43. It can be inferred from the passage that ________.
A. pets are ill-treated by their owners
B. fewer families would like to own cats and dogs
C. keeping pets is a good way to keep children healthy
D. the results of the study can make families with pets feel at ease
44. The underlined word “it” in the fifth paragraph refers to ________.
A. the early life B. an allergic disease
C. immune system D. something important
45. What may be the best title of the passage?
A. How to protect your kids from allergies.
B. Your pets may be helping your kids.
C. Bacteria do good to your kids.
D. Advantages of owning pets.
When a 13-year-old Virginal girl started sneezing, her parents thought it was merely a cold. But when the sneezes continued for hours, they called in a doctor. Nearly two months later the girl was still sneezing, thousands of times a day, and her case had attracted worldwide attention.
Hundreds of suggestions, ranging from “put a clothes pin on her nose” to “have her stand on her head” poured in. But nothing did any good. Finally, she was taken to Johns Hopkins Hospital where Dr. Leo Kanner, one of the world’s top authorities on sneezing, solved the baffling (难以理解的) problem with great speed.
He used neither drugs nor surgery for, curiously enough, the clue for the treatment was found in an ancient superstition(迷信) about the amazing bodily reaction we call the sneeze. It was all in her mind, he said, 
a view which Aristotle, some 3,000 years earlier, would have agreed with heartily.
Dr. Kanner simply gave a modern psychological interpretation to the ancient belief that too much sneezing was an indication that the spirit was troubled; and he began to treat the girl accordingly.
“Less than two days in a hospital room, a plan for better scholastic and vocational（职业的） adjustment, and reassurance about her unreasonable fear of tuberculosis（肺结核） quickly changed her from a sneezer to an ex-sneezer,” he reported.
Sneezing has always been a subject of wonder, awe and puzzlement. Dr Kanner has collected thousands of superstitions concerning it. The most universal one is the custom of begging for the blessing of God when a person sneezes— a practice Dr. Kanner traces back to the ancient belief that a sneeze was an indication that th
e sneezer was possessed of an evil spirit. Strangely, people over the world still continue the custom with the traditional, “God bless you” or something else.
When scientists look at the sneeze, they see a remarkable mechanism（身体机制） which, without any conscious help from you, takes on a job that has to be done. When you need to sneeze you sneeze, this being nature’s clever way of getting rid of an annoying object from the nose. The object may be just some dust in the nose which nature is trying to remove.

A. was ill B. was mentally ill
C. had heavy mental burden D. had attracted world-wide attention
52. When the girl began to sneeze continuously, ___________.
A. a lot of people offered their advice

A. using Aristole’s method B. giving her psychological treatment
C. practicing superstition D. treating her tuberculosis
54. When a person sneezes, we say “God bless you” because____________.
A. it’s a tradition B. the person is possessed of an evil spirit
C. the person is ill D. God will bless those who sneeze
55. According to scientists, people sneeze because _____________.
A. they are ill B. to sneeze is human nature
C. they do not need any conscious help D. there are unwanted things in their noses
Global warming may or may not be the great environmental crisis of the 21st century, but — regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments(承诺) to avoid it. But the more dramatic and meaningful these commitments seem, the less l
ikely they are to be observed.
Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and — without major technological breakthroughs — we can’t do much about it.
From 2003 to 2050, the world’s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions(排放) (mainly, CO2) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world’s poor to their present poverty and freeze everyone else’s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.
No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.” Con
sider the Kyoto Protocol(京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories(签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.
The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.
The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.
46. What is said about global warming in the first paragraph?
A. It may not prove an environmental crisis at all.
B. It is an issue requiring worldwide commitments.
C. Serious steps have been taken to avoid or stop it.
D. Very little will be done to bring it under control.
47. According to the author’s understanding, what is Al Gore’s view on global warming?
A. It is a reality both people and politicians are unaware of.
B. It is a phenomenon that causes us many inconveniences.
C. It is a problem that can be solved once it is recognized.
D. It is an area we actually have little knowledge about.
48. G
reenhouse emissions will more than double by 2050 because of ________.
A. economic growth
B. wasteful use of energy
C. the widening gap between the rich and poor
D. the rapid advances of science and technology
49. The author believes that, since the signing of the Kyoto Protocol, ________.
A. politicians have started to do something to better the situation
B. few nations have adopted real tough measures to limit energy use
C. reductions in energy consumption (消耗) have greatly cut back global warming
D. international cooperation has contributed to solving environmental problems
50. What is the message the author intends to convey?
A. Global warming is more of a moral issue than a practical one.
B. The ultimate solution to global warming lies in new technology.
C. The debate over global warming will lead to technological breakthroughs.
D. People have to give up certain material comforts to stop global warming.
