Two scientists in California now think they can find out a person’s real age.Jeffery Bada and Patricia Masters do chemical tests on teeth.When we are born the amino acids(氨基酸)in our teeth are in one form.Then,as we grow older these amino acids change into a second form.Every year,one thousandth of the amino acids changed.So,by testing just one tooth and counting the number of amino acids in each form,Bada and Masters can work out a person’s age.They tested a tooth from the body of an Eskimo(爱斯基摩人)woman who died 1 600 years ago.From the appearance of her body,she was between 50 and 60 years old when she died.The tooth test put her age at 53.Then the Russian Government sent them a tooth from an old man in Georgia.The tooth said she was 99.Her real age was 96.The Russians are now hoping to send more teeth,from the very old people without birth certificates(出生证明书).But there are problems.Some of the centenarians(百岁老人)have lost all their teeth.The others want to keep their teeth until they drop out naturally.So the Russian Government and the American scientists have to wait and hope.
61.Jeffery Bada and Patricia Masters believe that they can tell a person’s age according to_______.
A.an experiment on his bone
B.the shape and condition of his teeth
C.a test on the amino acids within his body

B.The number of amino acids in a 20-year-old man is different from that when he was seven.
C.Amino acids in one teeth changes without affecting their forms.
D.Scientists now can tell how long a person will live by testing his teeth.
63.Why are the two scientists asked to find out some very old Russians’ age?
A.Because the Government wants to know how long these old people can live.
B.Because they have no birth certificates.
C.Because people who have tooth problems tend to live longer.
D.Because the Government wants to know their dates of birth and death.
64.In order to find out the exact age of some people over 100,both the Russian Government and American scientists_______.

One of the most important things in the world is friendship. In order to have friends, you have to be a good friend. But how can you be a good friend at school?
Listen—Listen when they are talking. Don’t say anything unless they ask you a question. Sometimes it’s not necessary for you to have anything to say; they just need someone to talk to about their feelings.
Help them—If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don’t do everything they want you to do. Try to take an extra pencil or pen with you to classes in case they forget one. Have a little extra money in your pocket in case they forget something they need.
Be there for them—Be there for your friends to help make them feel better in hard times. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control, but if you can’t stay with me at my worst, you are sure not to deserve to be with me at my best.” Always remember this! If you don’t want to stay with your friends when they’re in hard times, then you don’t deserve to be with them when they’re having a good time!
_________—Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you’ll remember these things when you’re all old!While your friend is talking to you about his or her feelings, you should __________.
A.give him or her some advice | B.calm him or her down |
C.just listen unless asked | D.share your feelings as well |
What can we learn from Marilyn Monroe’s words?
A.Life without a friend is death. |
B.A friend is easier lost than found. |
C.A man is known by his friends. |
D.A friend in need is a friend indeed. |
Which of the following can be put in the blank of the last paragraph?

An ageing society is one in which the population of people over the age of 60 is increasing. This is a social problem. Can we solve it with the help of robots?
Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck,an expert in human animal relationship ,and Nancy Edwards, a professor of nursing, are leading the animal assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and left satisfaction. ”No one will argue that an older person is better off being more active, challenged, or stimulated(刺激),”Edwards points out.” The problem is how we promote (促进)that, especially for those without friends or help. A robotic dog could be a solution.”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
”I talk to him all the time, and he responds to my voice,” says a seventy year old lady, ”When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
”At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry.” Beck says.” But it’s amazing how quickly we have given up that belief.”
”Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels. Or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”Which of the following can be the best title?
A.Dogs and the Old |
B.Medical Examination and the Old |
C.Robots Serving the Old |
D.Dogs Needn’t Feeding |
The purpose of Beck and Edwards’ study is to____ .
A.understand humananimal relationship |
B.make lonely old people’s life better |
C.find the causes of old people’s loneliness |
D.promote the animalassisted research |
What is the advantage of AIBO over live dogs?
A.It is easier to keep at home. |
B.It can help the disabled people. |
C.It responds to all the human orders. |
D.It can watch TV with its owner. |
The author seems to suggest that the future robotic dogs may.
A.cure certain diseases |
B.keep old people active |
C.change people’s beliefs |
D.look more like real dogs |
I always felt sorry for the people in wheelchairs. Some people, old and weak, cannot get around by themselves. Others seem perfectly healthy, dressed in business suits. But whenever I saw someone in a wheelchair, I only saw a disability, not a person.
Then I fainted(昏倒)at Euro Disney due to low blood pressure. This was the first time I had ever fainted, and my parents insisted that I rest for a while after first aid. They said to me, “Never mind!” I agreed to take it easy, but as I stepped toward the door, I saw my dad pushing a wheelchair in my direction! Feeling the color burn my cheeks, I asked him to wheel that thing right back to where he found it.
I could not believe this was happening to me. Wheelchairs were fine for other people but not for me, as my father wheeled me out into the main street, people immediately began to treat me differently.
Little kids ran in front of me, forcing my father to stop the wheelchair suddenly. Bitterness set in as I was thrown back and forth.
”Stupid kids! They have perfectly good legs. Why can’t they watch where they are going?” I thought. People stared down at me, pity in their eyes. Then they would look away, maybe because they thought the sooner they forgot me the better.
”I’m just like you!” I wanted to scream.” The only difference is you’ve got legs, and I have wheels.”
People in wheelchairs are not stupid. They see every look and hear each word. Looking out at the faces, I finally understood: I was once just like them. I treated people in wheelchairs exactly the way they did not want to be treated. I realized it is some of us with two healthy legs who are truly disabled.What do the underlined words mean in Paragraph 2?
A.Don’t mind. |
B.Don’t worry. |

Many years ago the idea of disabled people doing sport was never heard of. But when the yearly games for the disabled were started at Stoke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change.
Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had been asked by the British government to set up an injuries centre at Stoke Mandeville Hospital near London. His ideas about treating injuries included sport for the disabled.
In the first games just two teams of injured soldiers took part. The next year 1949, five teams took part. From those beginnings, things have developed fast. Teams now come from abroad to Stoke Mandeville every year. In 1960 the first Olympics for the disabled were held in Rome, in the same place as the normal Olympic Games. Now, every four years the Olympic Games for the disabled are held, if possible, in the same place as the normal Olympic Games, although they are organized separately. In other years Games for the disabled are still held at Stoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about 40 countries took part. Unfortunately, they were held at Stoke Mandeville and not in Los Angeles, along with the other Olympics.
The Games have been a great success in helping the progress of international friendship and understanding, and in proving that being disabled does not mean you can’t enjoy sport. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include disabled events at the Olympic Games for the ablebodied. Perhaps a few more years is still needed to persuade those fortunate enough not to be disabled that their disabled fellow athletes should be included.The first games for the disabled were heldafter Sir Ludwig Guttmann arrived in England.
A.40 years |
B.21 years |
C.10 years |
D.9 years |

An entire industry has been built upon the assumption that image is everything, but when it comes to it, an appealing image is not enough.If there is no substance(事实)behind the image, the product, service or person will fail eventually.
First of all, one should consider how important image is in the selling of products and services.Advertising agencies have raised the art of creating an image to a state of near perfection.Public concept of that product or service is certainly managed by the images created by the advertising agencies.But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back.For example, the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness.But the recent scandal(丑闻)showed that behind that image, it cheated in business practices.Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit.Although the image had been nearly perfect, the reality, behind the image has led to the downfall of the word-famous accounting firm.
Similarly, personal advisers can build up a public image for politicians and movie stars.Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons.But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune.With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.
To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person.But image is only half of the equation(等式).What lies behind that image is every bit as important as the image itself—the person or product must deliver truth on that image or there is little chance for long-term success.The down fall of the Arthur Andersen accounting firm is due to ________.
A.its previous images. | B.its dishonesty in business. |
C.its bad management. | D.its poor service. |
Why did some famous people fall from grace?
A.They failed to live up to their images. |
B.Their images were not well built up. |
C.They felt much pressure from the public. |
D.They paid little attention to fame and fortune. |
The structure of the passage is _________.
A:ArgumentP:PointC.ConclusionThe author tries to argue that ________.
A.image creates everything. |
B.image is the key to success. |
C.truth is unlikely ever to be equaled. |
D.truth and image are equally important. |
