For more than twenty 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 on spaceships travelling through space, on the chance that someone may be receptive to such message.
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 channels at one 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 the evolution (进化) of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of 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 civilization 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.

One bitterly cold day, a snowstorm blew into our area. Needing firewood, I quickly set out with my best friend, Bruce, to look for a tree to cut down. I was glad to have Bruce along. Cutting down a tree in a snowstorm can be dangerous. So it was important to have a friend who could warn me of dangers.
When I chose a big 23-meter-tall tree and prepared to cut it down, my best friend suddenly warned me,“Don’t cut down that tree! It’s too close to the power line!”I wasn’t sure about it. So I decided to disregard his warning. I wanted to finish the job quickly and go home. So I began cutting down the tree. When the tree fell, there was no longer any doubt whether my friend was right.
The tree caught the power line, bringing it to the ground. I considered cutting the tree off the line. After all, electricity can’t travel through wood, so I could safely remove the tree. As I reached out my finger to touch the tree, pain ran up my arm and through my head. I had been shocked!
After I returned home and told my mother what had happened, she quickly called the power company. Workers from the power company soon arrived on the scene. One of them asked if I had touched the tree, and when I told him I had, his face turned pale.
“You should have been killed,”he said.
So why am I still alive? It was my boots that saved my life.
Within two hours, the workers removed the tree. Soon the snowstorm calmed down—but not my mother.
Even though she was glad I wasn’t hurt, my mother was still serious with me. After all, I shouldn’t have brushed off my friend’s warning.
Through this experience, I learned it’s important to listen to people who offer a different perspective. Taking the time to listen might actually save a lot of time and trouble. It certainly would have kept me from getting the“shock of my life.”

Reading poems is not exactly an everyday activity for most people．In fact, many people never read a poem once they get out of high school．
It is worth reminding ourselves that this has not always been the case in America．In the nineteenth century, a usual American activity was to sit around the fireside in the evening and read poems aloud．It is true that there was no television at the time, nor movie theaters, nor World Wide Web, to provide diversion．However, poems were a source of pleasure, of self-education, of connection to other people or to the world beyond one’s own community．Reading them was a social act as well as an individual one, and perhaps even more social than individual．Writing poems to share with friends and relations was, like reading poems by the fireside, another way in which poetry has a place in everyday life．
How did things change? Why are most Americans no longer comfortable with poetry, and why do most people today think that a poem has nothing to tell them and that they can do well without poems?
There are, I believe, three factors：poets, teachers, and we ourselves．Of these, the least important is the third: the world surrounding the poem has betrayed us more than we have betrayed the poem．Early in the twentieth century, poetry in English headed into directions unfavorable to the reading of poetry．Readers decided that poems were not for the fireside or the easy chair at night, and that they belonged where other difficult-to-read things belonged．
Poets failed the reader, so did teachers．They want their students to know something about the skills of a poem, they want their students to see that poems mean something. Yet what usually occurs when teachers push these concerns on their high school students is that young people decide poems are unpleasant crossword puzzles．
53. Reading poems is thought to be a social act in the nineteenth century because___________．
A. it built a link among people B. it helped unite a community
C. it was a source of self-education D. it was a source of pleasure
54. The underlined word “diversion” most probably means “___________”．
A. concentration B. change C. amusements D. stories
55. According to the passage, what is the main cause of the great gap between readers and poetry?
A. Students are becoming less interested in poetry．
B. Students are poorly educated in high school．
C. TV and the Internet are more attractive than poetry．
D. Poems have become difficult to understand．
56. In the last paragraph, the writer question___________．
A. the difficulty in studying poems B. the way poems are taught in school
C. students’ wrong ideas about poetry D. the techniques used in writing poem
“Can I see my baby?” asked the happy new mother. The bundle (婴儿包) was placed in her arms and when she moved the fold of cloth to look upon his tiny face, she held her breath—the baby had been born without ears. Time, however, proved that the baby’s hearing was perfect except his appearance.
One day when he rushed home from school and threw himself into his mother’s arms, he cried out bitterly, “A boy, a big boy … called me—a f-…freak.” She sighed, knowing that his life was to be endless of heartbreaks.
He grew up, handsome for his misfortune. A favorite with his fellow students, he might have been class president but for that. He developed a gift for literature and music.
The boy’s father had a talk with the family doctor. Could nothing be done? “I believe we could transplant on a pair of outer ears, if they could be donated ,” the doctor decided. So the search began for a person who would make such a sacrifice for a young man. Two years went by. Then, “You’re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’s a secret.” said the father.
The operation was brilliantly successfull. His talents blossomed into genius. School and college became a series of successes. Later he married and entered the diplomatic(外交) service. “But I must know!” he urged his father. “Who gave so much for me? I could never do enough for him.”
“I do not believe you could,” said the father, “but the agreement was that you are not to know … not yet.” The years kept the secret, but the day did come … one of the darkest days that ever pass through a son. He stood with his father over his mother’s casket(灵柩). Slowly and tenderly, the father stretched forth a hand and raised the thick, reddish-brown hair to let out the secret.

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”. Personally, I couldn’t do without the phone entirely, which makes me unusual, Because the telephone is changing our lives more than any other piece of technology.
Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been with at school all day. If the phone did not exist, would she have anything to talk about?
Point 2 The mobile phone means that we are never alone. “The mobile saved my life,” says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance to her rescue.
Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are , where they are going, and how their last meeting went.
Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”
Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously (同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access the Internet, the biggest library on Earth.
1．How do you understand ‘Point 1 —The telephone creates the need to communicate,…’？
A．People don’t communicate without telephone.
B．People communicate because of the creating of the telephone.
C．People communicate more since telephone has been created.
D．People communicate more because of more traffic.
2．Which points do you think support the idea that phones improve people’s life?
a．Point 1． b．Point2． c．Point3． d．Point 4． e．Point 5．
A．c, d B．a, e C．a, c D．b, e
3．It is possible to talk to several complete strangers simultaneously through .
A．the TV screen B．a fax machine
C．the phone line hooked up to the computer D．a microphone
4．The best heading for the passage is .
A．Phone Power B．Kinds of Phone
C． How to Use Phones D．Advantage of Phones

Bollworms are a traditional threat to cotton crops．Young ones feed on the boll，the part of the cotton plant that contains the seeds．
A bacterium known as Bt is able to kill bollworms and some other pests．Bt is the short form for Bacillus thuringiensis．It was discovered in the early twentieth century．Farmers began using Bt as a natural pesticide(杀虫剂)．
Then，in the 1990s，researchers found a way to grow cotton plants that contain a Bt gene．The genetically improved cotton plant produces liquid that kills bollworms．Farmers around the world are now growing an estimated fourteen million hectares of Bt cotton．
Cotton bollworms also attack other crops．But scientists in China recently reported that Bt cotton may help prevent bollworm in other crops growing nearby．
The study involved crops grown in six provinces of northern China between 1992 and 2008．The study area contained three million hectares of cotton and twenty-two million hectares of corn，peanuts，soybeans and vegetables．
The researchers say the study suggested that Bt cotton not only controls bollworm on the transgenic cotton，but also may reduce its existence on other crops．And that reduction，they say，may decrease the need for insecticide use in general．
But the researchers also pointed out concerns．They say bollworms could develop resistance to the cotton plants designed to resist them．And they noted that insects called mirids have become “key pests” of cotton in China．They said this is because of a decrease in pesticide use made possible by Bt cotton．
The researchers say they do not believe that Bt cotton alone can solve all insect problems．Instead，they say farmers in China should consider it just one part of pest management systems．
1．What is Bt in this passage?
A．It's a kind of hi-tech invention． B．It's a natural bacterium．
C．It's a kind of pest． D．It's a man-made pesticide．
2．Bt cotton has all the advantages EXCEPT that ________．
A．it resists bollworms
B．it does good to other crops growing around
C．it reduces the use of insecticide
D．it helps to develop new insects
3．The underlined word “ones” in the first paragraph refers to ________．
A．bollworms B．cotton crops C．cotton seeds D．pests
4．From the passage，we can infer ________．
A．farmers around the world are now growing a large area of Bt cotton
B．researchers are probably now searching for new ways to solve other cotton problems C．bollworms could not exist in Bt cotton any longer
D．Chinese scientists found the way to grow Bt cotton
