Do you want to live another 100 years or more? Some experts say that scientific progress will one day help humans to last tens of years longer than what is now seen as the natural limit(限制)of the human life span(壽命).
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate(保守估計).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said progress in using genes as well as nanotechnology(納米技術(shù))makes it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who research into aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also disagree on what kind of life the super aged might live. “It remains to be seen whether you could be healthy enough to have good quality of life when you pass 120.” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
小題1:By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A.they believe that there is no limit of living
B.they are sure to find the truth about long living
C.they have got some ideas about long living
D.they are able to make people live beyond the present life span
小題2:Donald Louria’s attitude toward long living is that_____.
A.people can live from 120 to 180
B.it is still doubtful how long humans can live
C.the human body is designed to last about 120 years
D.it is possible for humans to live longer in the future
小題3:The underlined “ it” (Para. 4) refers to_____.  
A.a(chǎn) great push
B.the idea of living beyond the present life span
C.the idea of living from 200 to 300
D.the conservative estimate
小題4:What would be the best title for this text?
A.Living longer or not
B.Science, technology and long living
C.No limit for human life
D.Healthy lifestyle and long living

小題1:C 推理題。根據(jù)本句we are knocking at the door of immortality (永生),指我們敲響了永生的門,說明我們已經(jīng)了解到了一些關(guān)于永生的秘密,結(jié)合第一段內(nèi)容可知C正確。
小題2:D 細(xì)節(jié)題。根據(jù)第二段最后3行“ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years說明他認(rèn)為人類永生是有可能的,故D正確。
小題3:B 推理題。這里的it就是指上一段里的“ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.活的時間超過現(xiàn)在的預(yù)測。故B正確。
小題4:A 主旨大意題。本文討論的主要就是人類在未來是否可以活的更久一點,故A項正確。
點評:對于人類是否可以活得更為久遠(yuǎn),文章中給出了答案。屬于科普類的短文,此類文章的最大的障礙是詞匯以及考生對閱讀內(nèi)容的不熟悉,需要考生在閱讀的時候有足夠的耐心。要養(yǎng)成在上下文串聯(lián)中猜測詞義的能力,根據(jù)上下文中出現(xiàn)的同義詞,近義詞,反義詞,以及詞義的解釋來理解生詞。同時要抓住文章的中心,不要受其他信息的影響。要根據(jù)題目及選項以及文章的上下文串聯(lián)合理的判斷推理。

根據(jù)短文內(nèi)容,從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。
Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas.  1  
Most Americans would find it hard to imagine what life would look like without cars. 2 . The polluted air becomes poisonous and dangerous to health.
 3 . That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of the car engine by something else.  4 . Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down.  5 .
Although cars have led us to a better life, they have also brought us new problems.
A.Thus the problem of air pollution would become less important than that of unemployment.
B.Americans know cars very well.
C.However, some have realized the serious problems of the air pollution that is caused by cars.
D.One way to get rid of the polluted air is to build a car that does not pollute.
E. However, the number of vehicles has continued to increase in recent years.
F. Americans won’t live without cars!
G. Inventors are now working on steam cars as well as electric cars.

From the health point of view we are living in a marvelous age. We are immunized (免疫) from birth against many of the most dangerous diseases. A large number of once deadly illnesses can now be cured by modern drugs and medical treatment. It is almost certain that one day cures will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the unbelievable slaughter (屠殺) of men, women and children on the roads. Man vs the motor-car! It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.
It has been rightly said that when a man is sitting behind a steering wheel (方向盤), his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man’s very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They are ill-mannered and aggressive, willful as two-year-olds and absolutely selfish. All their hidden disappointments and regrets seem to be brought by the act of driving.
The surprising thing is that society smiles so kindly on the motorist and seems to forgive his behavior. Everything is done for his convenience. Cities are allowed to become almost impossible to live in because of heavy tragic; towns are made ugly by huge car parks; the countryside is ruined by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten.
It is high time a world system of laws were created to reduce this senseless waste of human life. As for driving, the laws of some countries are not strict and even the strictest are not strict enough. Here are a few examples of some the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict annual tests for safety. Even the smallest amount of alcohol in the blood can affect a person’s driving ability. Present drinking and driving laws (where they exist) should be made much stricter. Maximum and minimum speed limits should be introduced on all roads. Governments should lay down safety specifications (規(guī)范) for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately severe. But surely nothing should be considered as too severe if it results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.
小題1:The main idea of this passage is _________.
A.Traffic accidents are mainly caused by motorists.
B.Thousands of people the world over are killed each year.
C.The laws of some countries about driving are not too strict.
D.Only stricter traffic laws can prevent accidents.
小題2:What does the author think of society toward motorists?
A.Society laughs at the motorists.
B.Huge car parks are built in the cities and towns.
C.Victims of accidents are nothing.
D.Society forgives their rude driving.
小題3:Why does the author say: “his car becomes the extension of his personality?”
A.Driving can show his real self.
B.Driving can show the other part of his personality.
C.Driving can bring out his character.
D.His car can express his temper.
小題4:Which of the followings is NOT mentioned as a way against traffic accidents?
A.Build more highways.B.Make stricter driving tests
C.Test drivers every three years.D.Raise age limit and lay down safety specifications.
小題5:The attitude of the author is  _________.
A.ironical B.criticalC.a(chǎn)ppealingD.favorable

As the father of a student, I have experienced first hand what a great teacher is. My son was in the 4th grade last year, and he had a teacher called Miss Green. I believe that when he is an adult he will surely look back on her as the best teacher he has ever had.
My son has attention deficit disorder(注意力缺損癥) that makes it a little more difficult for him to learn. She was able to change her teaching methods for him so that he could keep up with the rest of the class. As a result, he got straight As on many subjects. She regarded her class as a family and they even had their own class song. She would often have them sing it to encourage them and develop a team spirit for them. When she saw that they were no longer listening carefully to what she was teaching, she would have them close their textbooks, stand up all around the room and throw around a small football. This helped them clear their minds and then focus on the lesson again. Besides, she was quick to reply to any phone calls or emails from us and got rid of our worries about children quickly.
When my son went to the 5th grade this year, we happened to pass her classroom. When she saw my son, her face lit up(露出喜色) and she came out and hugged him. She generally loves all of the children in her classroom and that love really shows. I can only pray(祈禱) that my son will continue to get teachers just like her for the rest of his school years.
小題1:With the teacher’s help, the writer’s son ______.
A.became the best student in his class
B.was interested in singing songs
C.quickly finished his 4th grade lessons
D.improved his grades greatly
小題2:Which of the following is NOT true about Miss Green?
A.She regarded the students as members of a family.
B.She had special ways to help students study.

D.She usually made a quick reply to parents’ emails.
小題3:The underlined phrases “focus on” in Paragraph 2 means ______.
A.look forward toB.pay attention to
C.get away fromD.take care of
小題4:We can learn from the text that ______.
A.Miss Green was the best teacher at the school
B.a(chǎn)ll the students in the school liked Miss Green
C.Miss Green didn’t teach the writer’s son in the 5th grade

Today’s children are the “result” of the modern society. Our parents have jobs that keep them busy almost all day long. They only have a free day in a week. This doesn’t allow them to keep an eye on their children.
On the other hand, the modern society gives more freedom to the children than they could “handle”. As a child, you don’t know how to grow up by yourself until you reach a certain age. That is why you need school and parents to be by your side all the time. If you don’t have either of them you may make a lot of mistakes. The social system of the modern society is very lenient especially with the children.
Most of the children today are rebels (判逆者). They are rude. They are given too much freedom by their families. This is their parent’s mistake. They ought to know that the freedom they give to their children is misunderstood.
For example it is a bad thing for a 17 – year – old child to go out in the evening on weekends. Parents are also guilty of the way their children show up in the street or at school. The same guilt belongs to the teaching system as well. Pupils shouldn’t be allowed to dress like they were on a fashion presentation at school.
Another important fact we can think of regarding the freedom of children is their free will of spending money. Parents shouldn’t allow their children to spend money on whatever they want.
I think children are given too much freedom not only by their parents, but also by the society. The latter is more to be blamed!
小題1:The writer implies that parents’ busy lifestyle         .
A.makes their children become independent
B.may lead to a tense parent – child relationship
C.is harmful to their children’s health
D.is likely to create a troubled generation
小題2:What does the underlined word “l(fā)enient” (in Para 2) mean?
A.Not responsibleB.Not strict.C.Unkind.D.Unfair.
小題3:It seems that the writer agrees that students          .
A.should stay at home on weekends
B.can wear trendy clothes at school
C.had better wear school uniform at school
D.can be allowed to go out in the evenings
小題4:According to the writer, which of the following takes the primary responsibility for children’s problems?
A.The social environment.B.The educational system.
C.Each family.D.The school.

When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much.
But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line.
Ergonomics is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that’s working on a factory assembly line or sitting in front of a computer.
The monitor
You should not have to tilt(傾斜) your neck up or down to lock at the screen. Your eyes should be level with the top of the screen.
How far away should you sit? Reach your arm out so your fingertips just touch the screen.
The keyboard
It should be directly in front of you. Don’t unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists “neutral,” which means straight, not bent. This puts less strain on your nerves and muscles.
Arms should be close to the body. Don’t look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don’t have to reach for it.
The chair
Your feet shouldn’t dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there.
The Body
If you think of your body as a collection of right angles when you sit at a computer, you should be just fine.
Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat.
小題1:The passage mainly talks about        .
A.a(chǎn)voiding pains caused by using PCB.the science of ergonomics
C.illness caused by a computerD.how to keep fit
小題2:The underlined word “ergonomics” most probably means ______ in Chinese.  
A.管理學(xué)B.人機工程學(xué)C.機械工程學(xué)D.經(jīng)濟學(xué)
小題3:How high should a monitor be placed according to the passage?
A.As high as your arms.
B.A little higher than your eyes.
C.A little lower than your eyes.
D.At the same level as your eyes.
小題4:How shouldn’t a keyboard be placed?
A.Tilting away from you.B.Tilting up toward you.
C.Flat.D.Not mentioned.
小題5:How should you place your foot?
A.Rest them on a phone book.B.Rest them on the floor.
C.They should rest flat.D.They should dangle.
