Wikipedia is a free-access, free content Internet encyclopedia(百科全书), supported and hosted by the non-profit Wikipedia Foundation. Wikipedia is ranked among the ten most popular websites and is considered the Internet’s largest and most popular general reference book. Now, Wikipedia is becoming Wookiepedia as scientists hope the informative website will help us reach out to intelligent life forms. So aliens can learn about the human race.

Astronomers would like to beam (播送) the entire contents of Wikipedia into space in the hope of contacting aliens. They want to send messages to hundreds of star systems and planets 20 light years away using radio telescopes. The Search for Extraterrestrial Intelligence Institute, in California, wants to use powerful radio telescopes to try to reach Chewbacca and his mates in a galaxy（银河系）far away.

The plans will be discussed by astronomers at the weekend as some scientists fear the reply from ET might not turn out to be friendly. Institute scientist David Black said, “One question is if there are dangerous creatures we might be drawing their attention to ourselves. Another is if we go ahead, what message should be sent? There could be many civilizations out there，but if they are all listening and no one is broadcasting or responding, then nothing will happen.”

Professor Stephen Hawking, who has warned that intelligent aliens probably exist and we should keep a safe distance from them, is among those. “If aliens visit us, the outcome would be much as when Columbus landed in America which didn’t turn out well for the Native Americans,” he said.

Signals from Earth’s radio and TV broadcasts have been heading out in space for some 60 years reaching around 5,000 stars.

1.What does the underlined word those in the fourth paragraph refer to?

A. aliens from space

B. astronomers sending signals

C. scientists for the plans

D. scientists against the plans

2.What has Prof. Stephen Hawking warned?

A. intelligent aliens would probably land in America.

B. the plans will be in vain and nothing will happen.

C. none of the civilizations would reply.

D. aliens would bring disasters to the human race.

3.Which can be the best title?

A. Wikipedia, the most popular website

D. Wikipedia to result in a disaster

Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment . “We didn’t know at that time that there even was an environment, let alone that there was a problem with it, ”says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement . Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times, ”says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.

According to US government reports , emissions (排放) from cars and trucks have dropped from 10. 3 million tons a year to 5. 5 tons . The number of cities producing CO beyond the standard has been reduced from 40 to 9 . Although serious problems still remain and need to be dealt with , the world is a safer and healthier place . A kind of “Green thinking ” has become part of practices .

Great improvement has been achieved . In 1988 there were only 600 recycling programs , today in 1995 there are about 6, 600 . Advanced lights , motors , and building designs have helped save a lot of energy and therefore prevented pollution .

Twenty –five years ago , there were hardly any education programs for environment . Today , it’s hard to find a public school , university , or law school that does not have such a kind of program . ” Until we do that , nothing else will change! ” say Bruce Anderson .

1.According to Anderson , before 1970, Americans had little idea about ___

Different View

At age 14, 15 and 16, the way we looked was the most important thing in the world to us. My friends and I wanted nothing less than perfection.

In high school, we joined the gymnastics team, and our because even more important to us. We had no fat, only muscle. On the weekends, we would go to the beach, of our flat stomachs.

One summer day, all my friends were at my house . At one point, I was running back to the pool. I on a bee, and while it was dying under my foot, it stung (蛰) me. I instantly started to feel . That night, I began to run a high fever and my leg and foot were red, hot and swollen. I couldn’t walk. I could barely .

When my foot started to go numb, everyone became more . My foot was not getting enough blood. I had to go to the , and my leg hurt as if it were badly broken. I couldn’t move. All I could do was think about how soft my middle was becoming. That me more than any concern over my leg.

That would all when I heard the doctors mention possibly cutting off my foot. It was still not getting the supply it needed. The doctors would have to speed up their treatment.

Never before did I have such great for my foot. And walking seemed like a from the gods. Less and less would I want to hear my friends talk about and who was wearing what. More and more I expected visits from other kids in the hospital, who were quickly becoming my friends.

One girl came to visit me . Every time she came, she brought flowers. She was recovering from cancer and felt she should come back and the other patients.

She still had no hair, and she was swollen from medications she had been taking. I would not have given this girl a second before. I now loved every inch of her and looked forward to her .

Finally, I was improving and soon I went home. My leg was still swollen, I was walking, and I had my foot! When I would go back to the hospital, I often saw my friend. She was still visiting people and good cheer. I thought if even there was an angel on this earth, it had to be her.

John was waiting for the girl whose heart he knew，but whose face he didn’t，the girl with the rose．Thirteen months ago，in a Florida library he took a book off the shell and found himself interested in the notes in the margin(页边)．The soft handwriting showed a thoughtful soul and insightful(有洞察力的)mind．

In front of the book，he discovered the name，Miss Hollis Maynell. With time and effort he got her address．He wrote her a letter introducing himself and inviting her to keep in touch．

During the next year and one month the two grew to know each other through the mail．A romance started．John requested a photograph，but she refused．She felt that if he really cared, it wouldn’t matter what she looked like．Later they agreed on their first meeting—7:00 pm at Grand Central Station in New York．

“You’ll recognize me,” she wrote，“by the red rose I’ll be wearing my coat.” So at 7：00 he was in the station looking for the girl with the red rose．

A girl in a green suit was coming toward him，her figure long and slim and her eyes were blue as flowers．Almost uncontrollably came to her，and just at this moment he saw Hollis Maynell—a woman well past 40．The girl was walking quickly away．

He did not hesitate(犹豫)，saying，“I’m John，and you must be Miss Maynell．I am so glad you could meet me. May I take you to dinner?”

The woman smiled, “I don’t know what this is about，son，” she answered，“but the young lady in the green suit begged me to wear this rose on my coat．And she said if you were to ask me out to dinner，I should tell you that she is waiting for you in the restaurant across the street．She said it was some kind of test!”

It’s not difficult to admire Miss Maynell’s wisdom. The true nature of a heart is seen in its response to the unattractive.

2.Why did John uncontrollably go up to the young girl in the green suit?

A．Because he knew it was Miss Hollis Maynell.

B．Because she was the very lady he was waiting for.

C．Because he was drawn to her beautiful appearance.

D．Because John didn’t want to meet Miss Hollis Maynell

3.We can find John was a person who ________.

A．was easy to change his mind

B．was casual and independent

C．judged a person by his looks

D．valued a person’s inner spirit

4.What’s the theme of the story?

A．The wisdom is shown in one’s action.

B．Love can be met by chance if you like.

C．You should never judge a book by its cover.

D．A noble heart is seen in its response to the unattractive.

It is easy to lose patience with science today． The questions are pressing: How dangerous is air pollution? What about low-level radiation? When will that horrible earthquake strike California? And why can't we predict weather better? But the evidence is often described as "uncertain", forcing scientists to base their points of view almost as much on intuition（直觉）as on science．

When historians and philosophers of science listen to these questions, some conclude that science may not be able to solve all these problems any time soon． The unknowns can grow into riddles that are impossible to solve． Because of the unstable and changing state of the earth's atmosphere, for example, scientists have struggled for centuries to predict the weather with precision（精确） but failed．

The case is different for scientists of astronomy． For example, they think that the gravitational force of a nearby space vehicle, though tiny, is able to change the path of a much larger planet if the vehicle spends enough time close to it． With the aid of Newton's laws of gravitational attraction, ground controllers can predict the path of a planetary probe （探测仪）-or satellite-with incredible accuracy． They do this by calculating the gravitational force from each of the passing planets until the probe speeds beyond the edge of the solar system．A much more difficult task is to calculate what happens when two or three times of such force pull on the probe at the same time． Such procedures can, of course, be very difficult, but for experiments, they are effective．

This range of questions-from simple problems to those impossibly complex-has resulted in nicknames for various fields of study: "soft" sciences and " hard " sciences．“Soft” sciences admit a great degree of uncertainty． Academicians tend to judge fields such as sociology, psychology, and political science as “soft” because they are assumed to be understandable, of unnecessary mathematical accuracy, and concerned with everyday affairs such as interpersonal relationships． However, "hard" sciences, such as astronomy and chemistry, are said to offer precise answers． Precise definitions for "hard" sciences vary, but the characteristics of "hard" sciences include: producing testable predictions; performing controlled experiments; relying on quantifiable data and mathematical models; a high degree of accuracy and objectivity; and generally applying a pure form of the scientific method
