Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"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".
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（纳米技术）make 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 specialize in ageing 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 differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology(老龄学) Center. "At present people who could get to that point are not in good health at all."
【小题1】By saying "we are knocking at the door of 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 living forever |
| D．they are able to make people live past the present life span |

| C．No Limit for Human Life |
| D．Healthy Lifestyle and Long Living |
【小题1】C
【小题2】D
【小题3】B
【小题4】A
解析试题分析：本文是一篇科技说明文。文章就“人的寿命是否可以更长”科学家发表了不同方面的意见。
【小题1】C推理判断题。第二段Michaed Zey教授说 “我认为我们正在敲击永生之门，保守的估计，到2075年我们就会看到它的曙光”。由此可知他们有关于长生不老的一些想法。
【小题2】D推理判断题。由第三段可知Donald Louria 对待长生的态度是乐观的，他认为在将来人们有长寿的可能。可以活120～180岁甚至更久，200～300岁。A项表述得太具体。
【小题3】B 词义猜测词题。文章的前三个自然段讲述一些专家认为利用纳米和基因技术可以延长人类寿命，第四段则以However, many scientists who specialize in aging are doubtful about it…一句开头，转折说明许多科学家对此提出质疑，所以这个it指的是上文提出的观点。
【小题4】A主旨大意题。通读短文可知全文都在谈论人类是否可以更长寿的问题。部分专家学者很乐
观，也有部分专家并不这样看好。A项正好概括了这两个方面。文章虽提到了科学，技术，但它们只
是作为人类可以长寿的论据出现的。因此B项不对。C项只是部分人的观点。

Empathy(同情心) lets us feel another person’s pain and drives us to help. Do any other animals feel empathy? Scientists recently found that rats(老鼠) do, too.
Most people don’t like rats. In many people’s eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other’s pain.
Scientists placed pairs of rats in plastic cages(笼子) for two weeks. During this time they got to know each other. Then they put one of the rats from each pair into a small container(容器) in the cages. The small container had a door. It was so designed as to fall to the side when the free rat touched it. Many of the trapped(困住的) rats squeaked(吱吱叫) to show their discomfort. The other rats of the pairs could see their suffering(受苦的) friends clearly.
In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats’ favorite chocolate in the cages, but the rats didn’t eat it until they had saved their friends successfully. Scientists also found that female rats seemed to act more empathetic than male rats.
“The results are the first to show that rats take action in response to another’s trouble,” Decety said. “Monkeys and chimpanzees have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural.”
【小题1】A person with empathy is often _____.
| A．kind-hearted | B．clever | C．active | D．strong |
| A．Because they were not hungry at that time. |
| B．Because chocolate was not their favorite food. |
| C．Because they wanted to save the trapped rats first. |
| D．Because they were afraid that the chocolate was bad. |
| A．Monkeys. | B．Chimpanzees. | C．Rats. | D．Cats. |
| A．Rats can feel other animals’ pain. |
| B．Chocolate is rats’ favorite food. |
| C．Rats are empathetic and can feel each other’s pain. |
| D．Female rats are more empathetic than male rats. |

Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.
【小题1】From the passage, we know that Wagner Marcenes ______.
| A．works as the leader of the Institute of Dentistry at Queen Mary, University of London. |
| B．and his researchers accumulate some studies to find out some ways to cure all major disease. |
| C．is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies. |
| D．thinks that the most serious problem caused by tooth decay is cancer that will last for a long time. |
| A．is listed in the most common of all 291 major diseases and injuries which will last for a long time.. |
| B．is closely related to industrialized diet which calls for people to eat slowly. |
| C．increases in Africa now because developing countries are becoming developed countries. |
| D．will cause phychological disorder which will affect people’s communication. |
| A．arouse people’s concern about caries and take measures to deal with it. |
| B．tell the result of the Global Burden of Disease 2010 study. |
| C．warn people in Africa to adjust their diet to prevent caries. |
| D．tell doctors that caries affects a person’s quality of life. |
| A．indifferent | B．concerned | C．angry | D．negative |

Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors?
The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking.
One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green.
Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about!
These facts help to make more believable some of the “believe it or not” stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call “thinking” by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line.
Many stories are told of the fish that get away and the clever “old hand” ones that can’t be caught. The more often a fish is nearly caught, the more difficult it will be to interest it next time.
【小题1】The last two paragraph’s mainly discuss _________.
| A．whether a fish can think as man does |
| B．how a fish could escape from danger |
| C．how to catch a fish more easily |
| D．whether a fish is believable |
| A．Fish can hear and see |
| B．How clever is a fish? |
| C．Fish can play tricks |
| D．How scientists help fishermen. |
| A．it’s difficult to catch fish; |
| B．fish are cleverer sometimes than fishermen |
| C．fish seem to learn by their experience |
| D．fewer people will be interested in fish |

It's not about how much money you make, and it's not about who your daddy is. We're talking about being attractive in general, whether it's on a job interview or just gaining the respect of your colleagues . . .
Ask lots of questions
If you come across as a know-it-all (even if you really do know it all!), it really pushes people away. Rather, asking lots and lots of questions makes people feel like you care, you can be trusted.
Great body language
Your body language says a lot about you - it says whether you have confidence, or simply if you really care. Talking physically, it is one of the most important physical characteristics you need!
Stay busy
Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive. Always be busy with something, even if for some reason you have to make something up.
Show your pearly whites (or just smile)
Smile more, no matter how ugly your teeth are. I'm not kidding about this one. It's not all about the teeth. If you are smiling genuinely, you can draw everyone for 100 meters around to you.
Wear what fits
Wear clothing that fits you. For women, wearing tight pants or shirts is not attractive. Things that just fit you and your shape are the best but not tight. Wear things that fit you nicely, please . . . And for goodness sake, both sexes, stay away from logos and printed shirts! Most people you may ask do not find this attractive. Stop being some company's billboard(广告牌).
Be interested in other man
Be interested in the other person. Don't talk about. If you are truly interested in the person, it will come across. And if you want to talk about yourself, you'll find that putting the other person first actually opens him up to return the favor and ask you questions. See how fun this is?
【小题1】It is your ________ that makes you attractive.
| A．your family background |
| B．fashionable tight clothes |
| C．your appearance and your wealth |
| D．proper body language and behavior |
| A．always smile and show your pearly teeth |
| B．keep asking lots of questions |
| C．are interested in other people’s personal affairs |
| D．always wear clothes that fit you |
| A．gain praises from your boss and colleagues |
| B．look attractive among people |
| C．show that you are interested in your job |
| D．get promoted in your company |
| A．Wearing a shirt with printed logos |
| B．Keeping talking about your own experiences and talents |
| C．Staying still, not making any body language |

Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly bombarded with products that are hazardous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reverse damage to some extent.
【小题1】What is the probably the best title of the text?
A. Obese smoking and death B. Key findings about smoking
C Taking charge of your health D. Obesity and smoking
【小题2】Which of the following is true according to the text?
| A．Obese smokers are less likely to suffer from cancer |
| B．Obese smokers are more likely to suffer from cancer |
| C．Obese smokers .tend to gain fewer body mass index. |
| D．Obese smokers tend to get heavier than those Who never smoke |
| A．easy and possible | B．difficult and impossible |
| C．easy ant worthwhile | D．difficult but worthwhile |
| A．To inform the readers of the findings about obese smoking. |
| B．To warn the readers of the danger of obese smoking. |
| C．To tell us what obese smoking is. |
| D．To call on the obese smolkers to quit smoking. |

In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this.
We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycle them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if all of us think about the problem, we will have a better and cleaner planet in the future.
【小题1】This passage mainly tells us about ______.
| A．the problems we are facing today about environment and the ways to solve them |
| B．the unlimited natural resources in the world |
| C．our rivers are being polluted by waste from factories |
| D．the ways early man protected the environment |
| A．If we eat more vegetables, more food can be saved. |
| B．In the past, there was no need for people to think about environmental protection. |
| C．If we keep on cutting trees, forests will disappear. |
| D．We shouldn’t take more and more fish out of the sea, or there will soon be no fish left. |
| A．Man is cleverer than any other animal. |
| B．Man will destroy himself if he doesn’t solve the problem. |
| C．Modern fishing methods are helpful in our fishing industry. |
| D．We should make more laws in order to survive. |
| A．will never be used up | B．are being polluted |
| C．are as plentiful as in the past | D．are being used up very quickly |

He came into the room to shut the windows while we were still in bed and I saw he looked ill. He was shivering, his face was white, and he walked slowly as though it ached to move.
"What's the matter, Schatz?"
"I've got a headache."
"You better go back to bed."
"No. I'm all right."
"You go to bed. I'll see you when I'm dressed."
But when I came downstairs he was dressed, sitting by the fire, looking a very sick and miserable boy of nine years. When I put my hand on his forehead I knew he had a fever.
"You go up to bed," I said, "You're sick."
"I'm all right," he said.
When the doctor came he took the boy's temperature.
"What's is it?" I asked him.
"One hundred and two."
Downstairs, the doctor left three different medicines in different colored capsules（胶囊） with instructions for giving them. One was to bring down the fever, another a purgative(泻药), the third to overcome an acid condition. The germs of influenza（流感）can only exist in an acid condition, he explained. He seemed to know all about influenza and said there was nothing to worry about if the fever did not go above one hundred and four degrees. This was a light epidemic(传染病；传染性的) of flu and there was no danger if you avoided pneumonia（肺炎）.
Back in the room I wrote the boy's temperature down and made a note of the time to give the various capsules.
"Do you want me to read to you?"
"All right. If you want to, " said the boy. His face was very white and there were dark areas under his eyes. He lay still in the bed and seemed very detached（超然的；冷漠的）from what was going on.
I read aloud from Howard Pyle's Book of Pirates（海盗）;but I could see he was not following what I was reading.
"How do you feel, Schatz?" I asked him.
"Just the same, so far," he said.
I sat at the foot of the bed and read to myself while I waited for it to be time to give another capsule. It would have been natural for him to go to sleep, but when I looked up he was looking at the foot of the bed, looking very strangely.
"Why don't you try to sleep? I'll wake you up for the medicine."
"I'd rather stay awake."
After a while he said to me, "You don't have to stay in here with me, Papa, if it bothers you."
"It doesn't bother me."
"No, I mean you don't have to stay if it's going to bother you."
I thought perhaps he was a little lightheaded and after giving him the prescribed capsules at eleven o'clock I went out with my gun and the young hunting dog….I killed two quail(鹌鹑), and missed five, and started back pleased to have found a covey of quail close to the house and happy there were so many left to find on another day.
At the house they said the boy had refused to let anyone come into the room.
"You can't come in," he said. "You mustn't get what I have."
I went up to him and found him in exactly the position I had left him, white-faced, but with the tops of his cheeks flushed（发红）by the fever, staring still, as he had stared, at the foot of the bed.
I took his temperature.
"What is it?"
"Something like a hundred," I said. It was one hundred and two and four tenths.
"It was a hundred and two," he said.
"Who said so?"
"The doctor."
"Your temperature is all right," I said. "It's nothing to worry about."
"I don't worry," he said, "but I can't keep from thinking."
"Don't think," I said. "Just take it easy."
"I'm taking it easy," he said and looked straight ahead, He was evidently holding tight onto himself about something.
"Take this with water."
"Do you think it will do any good?"
"Of course it will."
I sat down and opened the Pirate book and began to read, but I could see he was not following, so I stopped.
"About what time do you think I'm going to die?" he asked.
"What?"
"About how long will it be before I die?"
"You aren't going to die. What's the matter with you? "
"Oh, yes, I am, I heard him say a hundred and two."
"People don't die with a fever of one hundred and two. That's a silly way to talk."
"I know they do. At school in France the boys told me you can't live with forty-four degrees. I've got a hundred and two."
He had been waiting to die all day, ever since nine o'clock in the morning.
"You poor Schatz," I said. "Poor old Schatz. It's like miles and kilometers. You aren't going to die. That's different thermometer（温度计）. On that thermometer thirty-seven is normal. On this kind it's ninety-eight."
"Are you sure?"
"Absolutely," I said, "It's like miles and kilometers. You know, like how many kilometers we make when we do seventy miles in the car?"
"Oh," he said.
But his gaze at the foot of the bed relaxed slowly. The hold over himself relaxed too, finally, and the next day it was very slack(松驰的) and he cried very easily at little things that were of no importance.

Working with a group of baboons (狒狒）in the Namibian desert, Dr. Alecia Carter of the Department of Zoology，Cambridge University set baboons learning tasks involving a novel food and a familiar food hidden in a box. Some baboons were given the chance to watch another baboon who already knew how to solve the task, while others had to learn for themselves. To work out how brave or anxious the baboons were, Dr. Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake.
She found that personality had a major impact on learning. The braver baboons learnt, but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did. In effect, despite being made aware of what to do, they were still too shy to do what the experienced baboon did.
The same held true for anxious baboons compared with calm ones. The anxious individuals learnt the task by observing others while those who were relaxed did not, even though they spent more time watching.
This mismatch between collecting social information and using it shows that personality plays a key role in social learning in animals, something that has previously been ignored in studies on how animals learn to do things. The findings are significant because they suggest that animals may perform poorly in cognitive (认 知的）tasks not because they aren’t clever enough to solve them，but because they are too shy or nervous to use the social information.
The findings may impact how we understand the formation of culture in societies through social learning. If some individuals are unable to get information from others because they don’t associate with the knowledgeable individuals，or they are too shy to use the information once they have it，information may not travel between all group members, preventing the formation of a culture based on social learning.
【小题1】What is the first paragraph mainly about?
| A．The design of Dr. Carter’s research. |
| B．The results of Dr. Carter’s research. |
| C．The purpose of Dr. Carter’s research. |
| D．The significance of Dr. Carter’s research. |
| A．Those that have more experience. |
| B．Those that can avoid potential risks. |
| C．Those that like to work independently. |
| D．Those that feel anxious about learning. |
| A．Some baboons are intelligent but slow in learning. |
| B．Some baboons are shy but active in social activities. |
| C．Some baboons observe others but don’t follow them. |
| D．Some baboons perform new tasks but don’t concentrate. |
| A．storing information |
| B．learning from each other |
| C．understanding different people |
| D．travelling between social groups |
