When I was a boy, I belonged to the Boy Scouts (童子军), so I used to go camping every summer, and once something happened which I have never been able to explain.
We were camping in a place above a river. After arriving, we all rushed down to the river and had a swim. Standing by the river, we noticed that it was surrounded (环绕) by cliffs (悬崖). If someone wanted to reach the river at this point, he had to walk past our camp.
Several days later, the scoutmaster had to be away for a day. That afternoon, we had supper early. We were sitting round the fire, eating and talking, when a man walked past and went down towards the river. We all felt that this man looked very strange, but, because each of us was afraid of looking very stupid, no one said anything.
We ate rather slowly, taking as long as possible. After finishing, we collected our plates together so that we could take them to the river where we always washed them. But no one moved towards the river—we stood looking at each other ashamed. Then all shouting at once, we began talking about the man who had walked past us. We agreed how strange he looked and we wondered what he could be doing by the river. We knew that he could only return by passing through our camp.
An hour passed. Then one of the boys suggested we should creep (悄悄移动) down by the river so that we could see what the man was doing. Moving very slowly and keeping in the shadow, we crept down towards the bank. One boy climbed a tree so that he could see everything clearly. He called to us that there was no one there, so we ran down to the bank, looking everywhere carefully. We could not understand where the man had gone.
When it got dark, we went back to our camp feeling bewildered. We told the scoutmaster what had happened in the evening. Smiling, he doubted if we had seen the man, but finally suggested we go and look again. We did, but there was no one there.
Many years have passed, but I still remember it as if it were yesterday. What did we see? I do not know.

Scientists have long believed one way to stop the Earth’s air from warming is by planting more trees. The idea is that more trees will take in or absorb(吸收) some of the CO2 in the air. CO2 is a gas released by cars, factories and other human activities. The gas traps heat in the Earth’s air, which warms the planet. However, two new studies have found that trees may not be as helpful in reducing CO2 as thought.
The first study was done at Duke University in Durham, North Carolina. Researchers pumped(打气) extra CO2 into a test area where green trees were growing. The trees grew thirty-four percent faster during the first three years. However, in time, the trees slowed to about their normal growth rate. The scientists say this is because trees need other nutrients(营养素), such as nitrogen(氮).
In the second study, researchers from Duke and Bowdoin College in Brunswick, Maine examined the soil(泥土) around trees. They discovered that as the leaves broke down into the soil, all the carbon was not trapped in the soil. Much of it was let into the air as CO2.
The findings of the two studies were published last month in Nature magazine. They suggest there is limited(有限的) value in planting trees to reduce the CO2 pollution in the air.
Forest planting has been a part of negotiations(谈判) on a world agreement to reduce greenhouse gases that scientists believe cause global warming. The United States, Canada, Japan and some other countries have supported the idea. But this new research suggests the idea is not as effective as environmental activists(积极分子) had thought. Scientist Ram Oren of Duke University led the study on tree growth. He says that earlier estimates(估计) on the ability of forests to absorb CO2 were overly hopeful.
Some other scientists say the research provides some of the first evidence on how trees react(反应) to CO2. Some other scientists say the research disputes(质疑) a belief among some coal and power companies. The companies say that more CO2 in the air will not create harmful global warming. Instead, they say it will increase forests and other plants.
1.Why did the researchers put trees in extra CO2 in the first study?
A. To learn whether trees can still absorb CO2 under extreme conditions.
B. To get more oxygen from these trees.
C. To know how much CO2 that trees can absorb.
D. To see the effect of CO2 on the growth rate of these trees.
2.What happened to the leaves falling from the trees in the second study?
A. They broke down and the main parts turned into oxygen.
B. They broke down and the carbon had mainly turned into CO2.
C. They broke down and the carbon was mainly absorbed in the soil.
D. They absorbed more CO2.
3.Scientist Ram Oren thinks that common beliefs of the tree’s ability to absorb CO2 are __________.
A. just right B. not acceptable
C. a bit too cheerful D. too dangerous
Experts know that a disaster is coming but they do not know when it will happen. They do know that it could cause a lot of damage. They think it will be worse than a hurricane. The disaster they are worried about is an earthquake.
There is a break in the earth’s crust (外壳). It is called the San Andreas Fault. The San Andreas Fault is in California. Many earthquakes happen along the San Andreas Fault. In 1989 there was a big earthquake on the fault. The earthquake was called the “Loma Prieta Earthquake”. Many people were hurt or died. Many buildings were ruined. Lots of people lost their homes. Roads and bridges were also damaged.
A large earthquake could happen in Southern California. Many small earthquakes have happened in the last year. Earthquake experts think that a large earthquake will happen there soon. They think a big earthquake will happen in the next few years.
The San Andreas Fault has many power lines stretched across it. There are water channels close to the earthquake fault. A large earthquake in Southern California would destroy energy and water supplies (供应). Lots of people would be without power or water for weeks. Buildings that have not been built strong enough would be destroyed. Not all hospitals would be able to help people who were injured. Many people would die or be homeless.
People need to be prepared. They need to know what to do if an earthquake happens. Everyone in California should have a survival kit at home. The emergency kit (应急箱) would include food and water. There should be medication and first aid supplies in the kit. A good survival kit will also have a portable radio, flashlights and spare batteries. All of the supplies in the kit should last at least 3 days.

F. Scott Fitzgerald, born on September 24, 1896, an American novelist, was once a student of St. Paul Academy, the Newman School and attended Princeton University for a short while. In 1917 he joined the army and was posted in Alabama, where he met his future wife Zelda Sayre. Then he had to make some money to impress her.
His life with her was full of great happiness, as he wrote in his diary “My own happiness in the past often got such joy that I could share it even with the person dearest to me but had to walk it away in quiet streets and take down parts of it in my diary.”
This side of paradise, his first novel, was published in 1920. Encouraged by its success, Fitzgerald began to devote more time to his writing. Then he continued with the novel the Beautiful and Damned (1922), a collection of short stories Thales of the Jazz Age (1922), and a play The Vegetable (1923). But his greatest success was the novel The Great Gatsby, published in 1925, which quick brought him praise from the literary world. Yet it failed to give him the needed financial（财政的） security(安全，保障). Then, in 1926, he published another collection of short stories All the Sad Young Men.
However, Fitzgerald’s problems with his wife Zelda had an effect on his writing. During the 1920s he tried to reorder his life, but failed. By 1930, his wife had her first breakdown and went to a Swiss clinic. During this period he completed novels Tender Is the Night in 1934 and The love of the last Tycoon in 1940. While his wife was in hospital in the United States, he got totally addicted to alcohol（酒精）. Sheila Graham, his dear friend, helped him fight his alcoholism.
