People bury treasure to stop other people from taking it. They choose a quiet place, dig a deep hole and bury the treasure in it. Then they make a map of where the treasure is or write down other clues（线索）that will help them or someone else to find it again.
In Britain a few years ago, a writer wrote about some treasure that he had buried. He put clues in the story to help readers find it. Thousands of people hunted for the treasure. They dug holes all over Britain, hoping to find it.
One of the most popular adventure stories ever written is Robert Louis Stephenson's “Treasured Island”, an exciting story about a young boy, Jim Hawkins, who is captured by pirates (海盗) and later finds some buried treasure.
Then there is the true story about a man who had to travel overseas for a year. He did not trust banks, so he buried his life savings in a park. Then he went away. On his return, he went straight to the park. But the park was no longer there. In its place there was a huge building.
And then there was the man who buried his savings, all in bank notes, in a waterproof（防水的）bag. When he dug it up years later, there was nothing left. Worms and insects had eaten the bag and everything in it.
And of course, these are stories about people who bury things and either forget where they have buried them or lose the map.

On the day of a big event, many people came to Big Bend Mountain to watch. John Henry and the salesman stood side by side. Even early in the day, the sun was burning hot.
The competition began. John Henry kissed his hammer and started working. At first, the steam-powered drill worked two times faster than he did. Then, he started working with a hammer in each hand. He worked faster and faster. In the mountain, the heat and dust were so thick that most men would have had trouble breathing. The crowd shouted as clouds of dust came from inside the mountain.
The salesman was afraid when he heard what sounded like the mountain breaking. However, it was only the sound of John Henry at work. Polly Ann and her son cheered when the machine was pulled from the tunnel of the mountain. It had broken down. Polly Ann urged John Henry to come out. But he kept working, faster and faster. He dug deep into the darkness, hitting the steel so hard that his body began to fail him. He became weak, and his heart burst.
John Henry fell to the ground. There was a terrible silence. Polly Ann did not move because she knew what had happened. John Henry’s blood spilled over the ground. But he still held one of the hammers. “I beat them,” he said. His wife cried out, “Don’t go, John Henry.”“Bring me a cool drink of water,”he said. Then he took his last breath.
His friends carried his body from the mountain. They buried him near the house where he was born. Crowds went there after they heard about John Henry’s death.

The TV shows a baby’s pram (婴儿车) rolling off a train platform as the mother makes a mad rush to save her son, but she is too late and it falls onto the rails in front of an incoming train. This heart-stopping scene happened yesterday at Ashburton station in Melbourne, Australia. But the story has a happy ending: the six-month-old baby survived with just a cut on his forehead, although the pram was dragged about 35 metres by the braking train. The nurse Jon Wright said the boy just “needed a feed and a sleep” and didn’t need to stay in hospital.
“Luckily, he was strapped (绑) into his pram at the time, which probably saved his life. I think the child is extremely lucky, ” Wright told the Herald Sun newspaper after the baby was taken to hospital with minor injuries.
Fortunately the train was already slowing down to stop at the station so it stopped quickly when the driver put on the brakes as soon as he saw the pram fall in front of him. Rail firm Connex is to look into how the pram rolled off the platform. The accident came one day after Connex started a child safety awareness activity warning parents to keep babies strapped into their prams at all times while on platforms.
The accident happened at the same time as the “balloon boy ”story in the US, in which a six-year-old Colorado boy was reported to be trapped in a flyaway balloon. However, he was later found hiding in the family’s garage. Many people believe that it had all been a publicity stunt by the parents. No such doubts surround the baby on the train platform.In the accident, the baby .
| A．almost fell onto the rails |
| B．needed to stay in hospital |
| C．was badly injured by the train |
| D．was pulled a long distance in the pram by the train |
The child was not killed most probably because.
| A．the mother strapped him into his pram |
| B．the platform is not very high |
| C．he was well fed and asleep |
| D．the mother rushed to save him |
Why could the train stop quickly?
| A．Because it had just begun to move. |
| B．Because it was moving slowly at that time. |
| C．Because the mother took measures quickly. |
| D．Because the driver saw the pram fall. |
The underlined word “stunt” in the last paragraph probably means .
| A．something silly | B．something funny |

The Red Panda isn’t much bigger than an average size house cat. At first you may think it’s a bear because of its name. They’re actually a member of the raccoon(浣熊) family which you can tell if you look at their appearance. The Red Panda has a long bushy tail that is useful in two ways. It helps them stay balanced when they are high up in the trees and it keeps them warm in cold weather. Their fur is thick and reddish brown, which may be why they’re known as the fire fox.
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.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 |
Which of the following is TRUE according to the passage?
| 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. |
What will Red Pandas do when they are in trouble?
| 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. |
The Red Panda holds onto the branches with its ____.
| A．tail | B．fur | C．back legs | D．claws |
Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
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.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 |
Earlier studies about northern forest fires ________.
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 |
The underlined phrase “soaked up” in the last paragraph most probably means ________.
| A．released | B．absorbed | C．created | D．disturbed |
From the text we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ______.
| 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 . |
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 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.”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 |
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 |
70. The underlined “ it” (Para. 4) refers to_____.
| 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 |
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. |
