Searching for life on other planets

For more than thirty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages, as well as messages on spaceships traveling through space, on the chance that someone may receive such messages.

Scientists are using powerful radio telescopes to “listen” to signals from about 1,000 stars, all within 100 light years of Earth. In addition, they will scan the entire sky to listen for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight million channels at a time. Scientists are looking for any signal that stands out from the background noise.

Of the 200 billion stars in the Milky Way galaxy, scientists find that five percent are like our sun. Perhaps half of them have a planet like Earth. Such a planet would be a reasonable distance from the star for temperatures to be right for life. Based on the planets in our galaxy, most scientists agree that one or more of these planets may support some life.

However, many scientists wonder whether intelligent life exists on other planets. Some believe that thirty years of searching without any intelligible messages shows that no one is out there. They say that intelligence comparable to ours is unlikely.

Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time some scientists think it is likely that civilizations much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

To look for signals from distant stars, scientists _____.

A. have sent up spaceships to other planets

B. have sent radio and television messages to outer space

C. are listening to the radio messages all the year round

D. will use computers to pick up background noise

According to the passage, how many planets in our galaxy might be inhabitable?

A. 5 billion.    B. 10 billion.  C. 15 billion.  D. 200 billion.

Some scientists believe no other planet has life because ______.

   A. most of the researches have been done over the radio

   B. thirty years of searching doesn’t have any result

   C. we didn’t send messages on spaceships

   D. none of the other stars is right for life

Some scientists think there might be more advanced civilizations on other planets because _____.

A. some planets support more advanced civilizations

B. some civilizations have sent us signals we can’t recognize

C. the evolution of intelligence on other planets is unlike ours

D. some planets in our galaxy are much older than the earth

Which of these statements is true based on the information in the passage?

A. The earth is one of the oldest planets in our galaxy.

B. Most scientists believe that there is intelligent life on other planets.

C. Scientists are trying different ways to find signs of life on other planets.

D. More advanced civilization than ours have developed on other planets.

We all have our ways of marking time. As a photographer, my life is measured from one story to the next. My oldest son was born in the middle of a long story about the Endangered Species Act. My daughter came along with a pack of gray wolves.

Twenty stories later, though, it’s the story in Alaska that I’ll remember best. It was the story about the loss of wilderness — and the story during which my wife Kathy got cancer. That’s the one that made time stand still. I stopped taking pictures on the day when she found that tumor (肿瘤). Cruelly, it was Thanksgiving. By Christmas, she had become very weak. Some days she was so sick she couldn’t watch TV.

Early examination saves time. But ours was not early. By the time you can feel it yourself, it’s often bigger than the doctor want it to be.

Cancer is a thief. It steals time. Our days are already short with worry. Then comes this terrible disease, unfair as storm at harvest time. But cancer also has the power to change us, for good. We learn to simplify, enjoying what we have instead of feeling sorry for what we don’t. Cancer even made me a better father. My work had made me a stranger to my three kids. But now I pay attention to what really matters. This is not a race. This is a new way of life and new way of seeing, all from the cancer.

In the end each of us has so little time. We have less of it than we can possibly imagine. And even though it turns out that Kathy’s cancer has not spread, and her prognosis (诊断) is good. We try to make it all count now, enjoying every part of every day.

I’ve picked up my camera again. I watch the sky, searching for beautiful light. When winter storms come, Kathy and I gather our children and take the time to catch snowflakes (雪花) on our tongues. After all, this is good. This is what we’re living for.

1.As a photographer, the author used to ______.

A. leave his daughter with a pack of gray wolves

B. express his love for his family in a special way

C. miss a great many important historical moments

D. devote much more to his career than his family

2.Why did the author decide to stop taking pictures?

A. To cure his own disease.                                    B. To spend more time with his wife.

C. To seek a better position.                                   D. To leave the wilderness alone.

3.What is the biggest change the cancer has brought to the author?

A. He treasured every bit of time with his family.

B. He has become a stranger to his children.

C. He takes his work more seriously.

D. He focuses more on medical care.

4.The author and his family catch snowflakes on their tongues probably because ______.

A. the snowflakes taste very good                       

B. snowflakes are what they feed on

C. they regard that as a way to enjoy life            

D. there is beautiful light in the snowflakes

Pacing and Pausing

Sara tried to befriend her old friend Steve's new wife, but Betty never seemed to have anything to say. While Sara felt Betty didn't hold up her end of the conversation, Betty complained to Steve that Sara never gave her a chance to talk. The problem had to do with expectations about pacing and pausing.

Conversation is a turn-taking game. When our habits are similar, there's no problem. But if our habits are different, you may start to talk before I'm finished or fail to take your turn when I'm finished. That's what was happening with Betty and Sara.

It may not be coincidental that Betty, who expected relatively longer pauses between turns, is British, and Sara, who expected relatively shorter pauses, is American. Betty often felt interrupted by Sara. But Betty herself became an interrupter and found herself doing most of the talking when she met a visitor from Finland. And Sara had a hard time cutting in on some speakers from Latin America or Israel.

The general phenomenon, then, is that the small conversation techniques, like pacing and pausing, lead people to draw conclusions not about conversational style but about personality and abilities. These habitual differences are often the basis for dangerous stereotyping (思维定式). And these social phenomena can have very personal consequences. For example, a woman from the southwestern part of the US went to live in an eastern city to take up a job in personnel. When the Personnel Department got together for meetings, she kept searching for the right time to break in --- and never found it. Although back home she was considered outgoing and confident, in Washington she was viewed as shy and retiring. When she was evaluated at the end of the year, she was told to take a training course because of her inability to speak up.

That's why slight differences in conversational style --- tiny little things like microseconds of pause --- can have a great effect on one's life. The result in this case was a judgment of psychological problems --- even in the mind of the woman herself, who really wondered what was wrong with her and registered for assertiveness training.

1.What did Sara think of Betty when talking with her?

A. Betty was talkative.                                                       B. Betty was an interrupter.

C. Betty did not take her turn.                              D. Betty paid no attention to Sara.

2.57. According to the passage, who are likely to expect the shortest pauses between turns?

A. Americans.                     B. Israelis.                 C. The British.            D. The Finns.

3.58. We can learn from the passage that ______.

A. communication breakdown results from short pauses and fast pacing

B. women are unfavorably stereotyped in eastern cities of the US

C. one's inability to speak up is culturally determined sometimes

D. one should receive training to build up one's confidence

After years of searching, a truth seeker was told to go to a cave, in which he would find a well. “Ask the well what is   36  , ” he was advised, “and the well reveal (告诉,揭露) it to you.” Having found the well, the seeker asked that most basic and important   37  . And from the depths came the answer: “Go to the village crossroad, and there you shall find what you are seeking.”

Full of   38   the man ran to the crossroad to   39   only three rather uninteresting shops. One shop was selling pieces of metal, another sold   40  , and thin wires were for sale in the third. Nothing and no one there seemed to   41   much to do with the revelation of truth.

Disappointed, the seeker returned to the well to demand an   42  , but he was told only: “You will   43   in the future.”

As years went by, the   44   of his experience at the well gradually   45   until one night, while he was walking, the sound of sitar (西塔琴) music   46   his attention. It was wonderful and it was   47   with great skill and inspiration.

Deeply  48  , the truth seeker felt drawn towards the   49  . He looked at the fingers dancing over the strings. And then suddenly he let out a cry of joyful   50  : the sitar was made out of wires and pieces of metal and wood just like   51   he had once seen in the three stores.

At last he understood the   52   of the well: we have already been given everything we need; our   53   is to assemble (聚集) and use them in the proper way. Nothing is   54   so long as we recognize only fragments (碎片). But as soon as the pieces are put together, something new appears, whose nature we could not have   55   by considering the fragments alone.
