Task 1: Stem Cell Research Script
Gregory: The Republican party in America is opposing stem cell research. I find it hard to beli eve that in this day and age, someone would do that.
Lillian: Stem cell research sounds pretty impressive, I?ll admit. But just what is it? Gregory: Well, a stem cell is a special type of cell. It is a general cell that, when it devides, can become any sp ecific type of cell.
Lillian: You mean, a stem cell can become a heart cell? Or a brain or a kidney cell? Gregory: That? s about it. Stem cells are a part of the body?s maintenance and repair system. When they div ide, they can become any cell type.
Lillian: I guess there would be some tremendous medical advantages in that sort of research. Gregory: You?ve said a mouthful. Recently, scientists were able to help a man who lost a jaw bone for cancer. They recreated bone material for his jaw from stem
cells. What it means is that since the new bone was created out of the person?s own cells, there was no problem with rejection because the DNA was the same.
Lillian: I bet the person was delighted. Why would anyone oppose that sort of
research? It would seem to have endless potential to benefit the human race.
Gregory: I agree, but there are people who think we should not interfere with nature
and manipulate “what is natural”.
Lillian: It?s easier to hold such a narrow view if you?re not in a position to need the benefits of th e research. If you?re missing a jawbone because of cancer, you probably support the research.
1. What is the passage mainly about? 2. Who is against stem cell research? 3. What is special abo ut a stem cell?
4. When can a stem cell become another cell type?
5. According to the passage, why do some people oppose stem cell research? Keys: 1.B 2.A 3.A 4.A 5.D
Task 2: The Improvement of Rice Script
Scientists now know a lot more about a grain that people have eaten for ten thousand years. (S1) Research teams around the world have completed a map of the (S2) genes of rices. The findings a ppeared last week in the (S3) journal Nature.
The aim is to speed up the improvement of rice. The scientists (S4) warn that the kinds of rice pla nts used now have reached the limit of their (S5) productivity. Yet world rice production must (S6) grow by an estimated 30 percent in the next twenty to meet demand. By 2025, as many as 4.6 bil lion people will depend on rice for (S7) survival. There is a lot of pressure on breeders to improve the crop, and the rice genome is a valuable tool to do that. (S8) Plant breeders have already used preliminary information from the rice genome to create experimental strains of rice that better re sist cold and pests.
The researchers also say rice is an excellent choice for genetic mapping and engineering. Rice gen es have only about 390 million chemical bases. That maight sound like a lot. But other major food grains have thousands of millions. (S9) The new map could better explain more than just rice. Ric e shares a common ancestor with other cereal crops. Because rice is the first cereal crop to be ful ly analyzed, researchers expect that sufficient knowledge of its genetic information will reveal the heredity of more complex grains, including corn, wheat and barley.
(S10) While significant progress has been made in the analysis of the rice genome, the mapping o f human genes is also making headway. When scientists can identify and manipulate genes that c ause certain diseases, mankind will cure them easily. The human genetic map may help us control a person?s height, weight, appearance and even length of life.
Task3: The First Cloned Cat
Script
In the age-old battle of cats and dogs, score one for the cats. Researchers at Texas A&M Universit y recently announced that they have successfully cloned a cat name Rainbow— the first pet ever c loned — after several years of unsuccessful efforts to clone a dog name Missy.
The ork, financed by a company hoping to provide pet-cloning services to wealthy owners, adds c ats to a growing list of successfully cloned animals that includes pigs, sheep, cattle and mice. The success demonstrates cloning is a technology that could be transferred to other animal famili es as well. The accomplishment may provide new tools for studying diseases such as cats? AIDS, a valuable research model for AIDS in humans.
Research into animal cloning remains an important scientific alternative until the issue of human cloning is settled. And that seems unlikly in the immediate future, for it involves religious and mo ral principles. There are, for example, groups that insist no one should be allowed to take on the r ole of God the Creator.
To create cloned cat embryos for the experiment, researchers transferred DNA from adult cat cell s into egg cells stripped of their own genetic information. Out of 82 attempts with cloned embryo s, one attempt resulted in a failed pregnancy, and another yielded a kitten named CC, delivered fr om a surrogate mother on December 22. The kitten?s name refers to “Carbon Copy” and “Copyca t”, the name of the cloning project.
Cloning attempts with dogs have proven unsuccessful in part because dogs?reproductive cycles a re more complicated.
The technique may also work with endangered cats such as the African wildcat, fishing cat and bl ackfooted cat.
Ironically, the increased knowledge of cat reproduction may best be suited for developing cat con traceptives to control the U.S. cat population. 1.Which of the following would be the best title for the passage?
1. What did researchers at Texas A&M University recently announce?
2. Which animals are NOT mentioned in the passage as having been cloned?
3. According to the passage, why is human cloning unlikely to happen in the near future?
4. What does the passage say about the pregnancy and birth in cat cloning? Keys: 1.A 2.B 3.C 4. B 5.C
VI. Further Listening and Speaking
Task1: Confident enough to control your fate? Script
Some people are born with the belief that they are masters of their own lives. Others feel they ar e at the mercy of fate. New research shows that part of those feelings are in the genes. Psychologists have long known that people confident in their ability to control their fates are mor e likely to adjust well to growing old than those who feel they drift on the currents of fate. Two researchers who questioned hundreds of Swedish twins report that such confidence, or lack of it, is partly genetic and partly drawn from experience.
They also found that the belief in blind luck— a conviction that chance plays a big role in life— is s omething learned in life and has nothing to do with heredity.
The research was conducted by Nancy Pedersen, a professor of psychology at the University of So uthern California in Los Angeles. The results were recently published in the United States in the J ournal of Gerontology.
People who are confident of their ability to control their lives have an “internal locus of control”, and have a better chance of being well adjusted in their old age, said Pedersen. An “external locu s of control”,believing that outside forces determine the course of life, has been linked to depress ion in latter years, she said.
“ We are trying to understand what makes people different. What makes some people age slowl y and others have a more difficult time?” she said.
The study showed that while people have an inborn tendency toward independence and self-con fidence, about 70 percent of this personality trait is affected by a person?s environment and lifeti me experiences.
Pedersen?s studies, with various collaborators, investigate the aging process by comparing sets of twins, most of whom were separated at an early age.
The subjects were drawn from a list first compiled about 30 years ago, registering all twins born i n Sweden since 1886. The complete list, which was extended in 1971, has 95,000 sets of twins. 1. Which of the following is concerned with blind luck?
2. Which of the following is related to an external locus of control?
3. According to the passage, what is true of one?s inborn tendency towards self-confidence?
4. What subjects were mostly used in Pedersen?s studies? 5. What is the main idea of the passag e?
Keys: 1.A 2.B 3.C 4.C 5.D
Task 2: Is it moral to clone humans?
Script
Laura: Did you hear about that peculiar cult that claimed to have created the world?s
first human clone?
Ian: Yeah, I did! They also said that it was aliens that created life on earth over
25,000 years ago. What are they on?
Laura: I know! It was so obviously just part of an elaborate hoax to bring publicity to
their crazy movement. But I don?t think the truth can be far off. Scientists have been working on i t for years.
Ian: Sure, but most scientists are working on cloning human cells or body parts that can be used to repair or replace damaged organs. Not complete human beings! That?s just science fiction! Laura: Well, the science may seem to be very advanced, but the idea is not a new one.
In A Journey to the West, Sun Wu-kung, the Monkey King, can clone himself from the hairs on his head. He just plucks a few hairs, chews them a bit, and when he spits them out, they change into replicas of him!
Ian: Really? Now that would be cool! You could send your clone to school while
you went to the cinema, and then it could do your homework! Wow! Now that I think of it, it wou ld be kind of fun to have a clone!
Laura: You would say that! Don?t you think it?s slightly immoral? I mean, it?s just
like having a slave. Doesn?t the clone deserve a life of his own?
Ian: Sure, but human beings must learn to strike a balance between the welfare of
a patient and of a clone.

Throughout the day, energy rises and falls. At its peak, you're likely to perform 30 to 40 percent faster and more accurately, than at its lowest, says Lynne Lamberg. So by synchronizing your schedule with your natural energy supply ,it will help you use it more efficiently.
She also says, alertness is highest and concentration the most between 9a.m. and early afternoon — the best time to crunch numbers or write a report. You should dive into the hardest tasks first, and your extend high-energy mornings with a late lunch. Many people are still going strong until 1 or 2 p.m., so why break the momentum?
During mid-afternoon, you might attend to some routine tasks, such as paying bills or sorting through a pile of junk mail. Work that involves physical activity, such as running down the hall to
photocopy a memo, or talking to other people (that includes phone calls)— will keep your energy level from dropping way down.
When full alertness returns— around 4 p.m.— you might do a few small projects that give you a feeling of satisfaction and accomplishment. Send off an important letter. Or plan and prioritize for the next day.
The dark side of your cycle is equally important: For daylong energy we need a good night's sleep. On average, Americans get about seven-and-one-half hours, although some need more and others get by on less. We 're getting enough sleep if we wake up without the help of an alarm clock and don't feel the urge to nap during the day.

Ex2: T F T T F
Script:
(Do you feel depressed when you read newspapers? Does the news always seem bad? To many people it does, but not to Alexander Dubois, a French scientist living in London. Unlike many scientists, he believes that the world will be a better place in the future. His book, What a Wonderful Life, will be on sale, and Globe sent Reporter Catherine Brown to talk to him. Here is part of their conversation.)
Catherine Brown: What changes will we see in the next few years?
Alexander Dubois: Today, work is the most important part of many people's lives. In the future, machines will do much of our work. This means that we'll have more time to think about how to live happily.
Catherine Brown: What developments will there be in medical science?
Alexander Dubois: The day will come when we will eliminate killer diseases such as diphtheria and typhoid. Also, there will be fewer babies
born with birth defects because doctors will be able to operate on children before they are born.
Catherine Brown: And what about natural resources? Will there be an adequate supply of coal, oil and gas?
Alexander Dubois: Of course! Research shows that there are sufficient resources for the next 20,000 years within one kilometer of the earth's
surface.
Catherine Brown: Will cities continue to grow and become more and more
overcrowded?
Alexander Dubois: No, they won't. People will return to smaller communities
where they can really know their neighbors and participate in community life.
Catherine Brown: Aren't you worried about the possibility of nuclear war?
Alexander Dubois: Yes, I am. I expect there will be a nuclear war in the future,
but it won't end our world. Life will continue.
Statements:
1. Alexander Dubois holds an optimistic point of view for the world's future.
2. Alexander Dubois believes that, people's jobs will play the most important part in their lives.
3. Alexander Dubois thinks that,6 some defects in babies will be treated before birth.

Scripts:
Professor Zimbardo: Time perspectives are easy to identify when people are making decisions. For some people, it’ s only about what is in the immediate situation, what other people are doing, and what they are feeling. And those people, when they make their decision in that form, we’ re going to call “ present-oriented ” , because their focus is what is now.
Student A: Then maybe , I’ m not ” present-oriented ” . It seems what I care most is always what will be in the future.
Professor Zimbardo: Yes. You might be among those ” future-oriented ” . There focus is always about anticipated consequences. OK, anybody here who is neither “ present-oriented ” nor “ future-oriented ” ?
Student B: Myself. I think neither of your description about this two time perspectives fits me well.
Professor Zimbardo: Then you mast belong to the third type. We call them “ pat-oriented ” because they focus on what was. For them, both the present and the future are irrelevant. Thire decisions are based on past memories.
Student B: That’ s true, but sometimes, I just fell my time perspectives are a mixture. Professor Zimbardo : That ’ s very likely the case. There are actually six time perspectives: past-positive or past-negative; present-hedonistic or present-fatalist: future-oriented or transcendental future, as a matter of fact, these six time perspectives might coexist in a person. But they are biased in different situations. Either of them may rise to be the dominating one that influences us to make decisions. But we’ re totally unaware.
Student A : But do those perspectives show bias in their influence on human life, for example, positive or negative?
Professor Zimbardo: In a sense, that’ s right. Any time perspective in excess has more negatives than positives, you know what those future-oriented people sacrifice for success. They sacrifice family time . they sacrifice friend time. They sacrifice fun time. And they sacrifice sleep. So it affects their health. And they live for work, achievement and control.
Student B: Yes. That’ s ture. We just never realized that before. But professor, do you think time perspective is something inherent or something we learn?
Professor Zimbardo: People ’ s time perspectives result from the social environment and their life experiences, and they can be learned and be changed . That’ s the last point I want to make today.
one needs to develop the mental flexibility to shift time perspectives fluidly, depending on the demands of the situation; that’ s what you’ re got to learn to do. The optimal temporal mix is What you get from the past-positive gives you roots. What you get from the future is wings to soar to new destinations, new challenges. What you get from the present hedonism is energy, the energy to explore yourself, places, people, sensuality.

Around the Corner
by Henson Towne
Around the corner I have a friend,
In this great city that has no end.
Yet the days go by and weeks rush on,
And before I know it, a year is gone.
And I never see my old friend's face,
For life is a swift and terrible race,
He knows I like him just as well,
As in the days when I rang his bell,
And he rang mine.
But we were younger then,
And now we are busy, tired men.
Tired of playing a foolish game,
Tired of trying to make a name.
Just to show that I'm thinking of him.
But tomorrow comes and tomorrow goes,
And distance between us grows and grows.
Around the corner! — yet miles away.
And that's what we get and deserve in the end.
Around the corner , a vanished friend.

Script:
Almost every American wears a watch, and in nearly every room in an American home,
there's a clock.
The desire to save time and handle work efficiently also leads Americans to buy many kinds of machines. These range from household appliances to equipment for the office such as calculators, photocopy machines and computers. One popular machine is the videocassette recorder, which gives Americans a new kind of control over time. Fans of professional football don't have to miss the Sunday afternoon game on TV because of a birthday party. They simply videotape it and watch the game in the evening. What's more, they can actual save time by fast-forwarding through all the sales ads and commercials shown during te game. So a 3.5-hour game, seen later on, might only last 1.5 hours.

Script:
What will life be like 100 years from now? Some experts are optimistic; others, far more pessimistic. They think that by then the population will have doubled. We will have run out of essential materials, like oil and coal. We may even have run out of water to drink. They believe that we will be living like chickens- living in little boxes, and eating artificial food.
But those who are more optimistic say that life in the future will be much better than it is today. We may be living in well-designed , systematic communities. We may be getting more sunlight, breathing fresher air, living in a better environment and leading far more pleasant lives than we are today.
Life will certainly have become far more mechanized by the year 2100. It may even have become too mechanized. Mechanization has already caused quite a few problems and will cause still more. For example, many jobs will have been “automated”. People will no longer be able to learn only one job in their lifetime. Many of the jobs that young people are doing today will have become unnecessary by the time they are 40.

4) Because they want to change them into apartment buildings
5) It saves people time for traveling back and forth
Script:
Starting in the early 1900s, many Americans living and working in large cities moved to the suburbs. They wanted to live where they could have a large house and yard, instead of a small apartment with no yard. The problem that this has brought is that as the cities have grown larger, people must travel a long way to their place of work. Often the trip takes as much as two hours each way. Thus they have very little time to enjoy their houses and yards.
Therefore, during the last decades of the 20th century, some people became interested in moving back to the business areas of the cities. Many old buildings with businesses or factories on the first few floors have upper floors that are empty- Other old buildings are completely empty. Architects have been buying these buildings and changing them into attractive apartment buildings. Most have large comfortable rooms with big windows, which let in a lot of light. The apartments in these buildings are quickly bought by people who want to move back downtown. As one new apartment owner said,
