The family took the duck to a doctor who treats animals．The doctor gave the duck to the Goose Creek Animal Sanctuary(动物保护区)．Animal sanctuaries provide homes for animals and teach people about their care．
The doctor said it was easy to understand why people thought the duck was dead. He said ducks generally do not move a 1ot，especially after being shot．And he said its low body temperature helped it survive in the refrigerator．
That was enough to make the duck famous around the world．The Tallahassee newspaper published the story that was re-printed in many different countries．But that was not the end of the story．
Workers at the wildlife sanctuary named the duck Perky．And they got the doctor to give an operation to repair the duck’s damaged wing．During the operation，Perky stopped breathing--not just once but two times．The doctor tried to save Perky by giving her oxygen．But he finally said the duck had died．A few seconds later, however, Perky began to move．Reports say the people in the operating room were so happy that they cried.
Workers at the wildlife sanctuary say Perky will not have any more operations. It seems the drugs that were used had side-effects on her．Perky is expected to live at the sanctuary．And a local company has begun to sell T-shirts showing a picture of the lucky duck. Money from the sale of the shirts will help pay for Perky’s care．

The Red Panda can be found in forested mountains. They’re originally from the forested mountain in the Himalayas in India, Nepal and Southern China. Bamboo is the most important part of their diet. They only eat the young leaves and shoots (嫩芽) of a bamboo plant. Red Pandas have a very low metabolic(新陈代谢的) rate in order to deal with their low energy diet and cool environmental temperatures.
They’re very shy and gentle and don’t hang around the wild too much during the day. If they feel endangered, they’ll stand on their back legs and make a hissing(嘶嘶) sound. Red Pandas are good climbers and spend most of their time living mainly in trees. Their claws are very strong and help them hold onto the branches. They sleep in an unusual way by curling up tightly and wrapping their tails around their heads while sitting on a branch. Sometimes they’ll sleep with their head beneath their chest and behind their back feet. This is the same position as an American raccoon sleeps.
小题1:You can tell that the Red Panda is a member of the raccoon family from ____.
| A．its name | B．its appearance | C．its diet | D．its living place |
| A．The Red Panda can only be found in India, Nepal and Southern China. |
| B．The Red Panda’s tail can help it stay balanced when it is high up in the trees. |
| C．The Red Panda eats the whole of the bamboo. |
| D．The Red Panda has high metabolic rate when the temperature is low. |
| A．They will hang around the wild during the day. |
| B．They will climb into the trees. |
| C．They will wrap their tails around their heads. |
| D．They will stand on their back legs and make a hissing sound. |

“ 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 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 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 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.”
小题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 living forever |
| D．they are able to make people live past the present life span |
| 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 |
| A．a 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 |
| A．Living longer or not |
| B．Science, technology and long living |
| C．No limit for human life |
| D．Healthy lifestyle and long living. |
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
小题1:According to the new findings, taking steps to prevent northern forest fires may _______.
| A．result in a warming climate |
| B．cause the forest fires to occur more frequently |
| C．lead to a longer fire season |
| D．protect the forests and the environment there |
A．analyze  all aspects of how northern fires influence climate |
| B．indicate that forest fires will pollute the atmosphere |
| C．suggest that people should take measures to protect environment |
| D．suggest that the fires will speed up climate warming |
| A．released | B．absorbed | C．created | D．disturbed |
| A．warm the climate as the assumption goes |
| B．allow more snow to reflect more sunlight into space and thus cool the climate |
| C．destroy large areas of forests and pollute the far-off sea ice |
| D．help to gain more energy rather than release more energy . |
“Helping survivors (生还者) of the earthquake and killer waves in the Indian Ocean last week is a race against time” says Kofi Annan , the United Nations secretary-general .
The concern about offers of international aid is based on history. Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our aim to give and receive support from one another under stressful surroundings. Social support consists of the exchange of resources among people based on their interpersonal ties.
Those of us with strong support systems appear betterable to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over a range of illnesses, from depression to heart disease, show that the presence of social support helps people prevent illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways. First, friends, relatives, and co-workers may let us know that they value us. Our self-respect is strengthened when we are popular with others despite our faults and difficulties. Second, other people often provide us with informational support. They help us to notice and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting(转移...注意力)us from our worries and troubles. Finally, other people may give us instrumental support: a financial aid, material resources, and needed services -- that reduces stress by helping us deal with our problems.
59. Research shows that people"s physical and mental health _______.
A. depends on the social welfare (福利)systems which support them
B. has much to do with the amount of support they get from others
C. depends on their ability to deal with daily worries and troubles
D. is closely related to their strength for dealing with major changes in their lives
60. The underlined word" cushions" in Para.3 means _______.
A. adds up to B. does away with
C. reduce the effect of D. depends on
61. Helping a sick neighbor with some repair work is an example of _______.
A. instrumental support B. informational support
C. social companionship D. the strengthening of self-respect
62. Social companionship is very important because _______.
A. it helps strengthen our ties with relatives
B. it enables us to get rid of our faults and mistakes
C. it makes our leisure-time activities more enjoyable
D. it draws our attention away from our worries and troubles
In ancient times, people had to use the sun and the moon to tell time. They got up when the sun came up and worked in the fields until the sun went down.
Man-made things
The sand clock is made of two glass balls joined by a narrow neck. The top ball was filled with sand. The sand slowly moved through the neck into the bottom ball. People knew how much time had passed when all the sand had fallen to the bottom ball.
People also made the water clock. They made a small hole near the bottom of a pot. Then they filled the pot with water. Markings inside the pot showed how much time passed as the water dripped (滴) out of the hole.
Nature’s Clocks in Living Things
◆Animals’ Body Clock
Animals do not need clocks to know time. They have a way of telling time by their bodies. Birds know when to fly to warmer places before winter. Some animals know when to keep more food for the cold winter months. Some fish know when it is time to move up the river and lay eggs.
◆Plants have their own clocks
Plants also have their own clocks to keep time. Plants know when to open flowers or when to drop their leaves.
◆The Body Clock in Human Beings
People also have their own body clocks. When we get used to our lives, our body clocks can be very accurate (准确的). It can tell us when it is time to wake up. It can also tell us when to eat or to go to sleep.
