A new report said scientists may not be far from giving apes the ability to think and talk like humans. The report is about experiments which transplant human cells into animals for medical purposes.
It claimed that concerns about the creation of talking apes should be taken seriously. It should also draw people’s attention to the possibility that the medical research about creating “humanised” animals is going to generate monsters.
A regulatory(监管的)body is needed to closely monitor any experiments that many risk creating animals with human-like consciousness or giving them any appearance or behavioural traits that too closely resemble humans, the report said.
Scientists would, for example, be prevented from replacing a large number of an ape’s brain cells with human brain cells until more is known about the potential risks. This has already been done in simpler animals like mice, which is judged to be less risky.
Under the new UK guidelines, the power to regulate tests on animals containing human material would be transferred to a body with wider responsibility for animal testing in the Home Office.
While there is no risk from experiments currently being carried out in Britain, it is possible that ethical (道德的) boundaries could be crossed within the next few years if scientists are not careful, the experts said.
Professor Thomas Baldwin, a member of the Academy of Medical Sciences working group that produced the report, said the possibility of humanised apes should be taken seriously.
He said, “The fear is that if you start putting very large numbers of human brain cells into the brains of primates(灵长类动物)you might transform the primates into something that has some of the abilities that we regard as distinctly human, such as speech, or other ways of being able to manipulate or relate to us.”
Professor Martin Bobrow, chair of the academy working group that produced the report, said, “The very great majority of experiments present no issues beyond the general use of animals in research and these should continue to proceed under the current regulations.”
Lord Willis, chair of the Association of Medical Research Charities, said, “AMRC only supports research that is absolutely necessary and where no suitable alternative methods are available.”

Strategy 1: Bring your own cup to Starbucks |
|
|
You'll get a 10-cent discount, and it's one less paper cup to end up in a dustbin |
The store won't create more waste when they throw away a cup |
|
Strategy 2: Turn off your computer |
|
|
When in standby mode, your PC is still using energy |
Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds |
|
Strategy 3: Reuse plastic bags |
|
|
Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag |
You're reducing pollution. The amount of oil it would take to make just 14 plastic bags would run your car for one mile |
|
Strategy 4: Use recycled paper in the bathroom |
|
|
Most of the toilet paper we use is made from trees found in forests previously untouched by humans |
If every household replaced one roll of toilet paper with a recycled one,424,000trees would still be standing. Look for eco paper towels too |
|
Strategy 5: Buy energy-efficient appliances(电器) |
|
|
Replace the old fridge with an Energy Star appliance and you'll use 15 percent less energy. It might be a little expensive to buy, but you'll save money on your electricity bills and help the environment |
If we all used one Energy Star appliance at home, it would be like planting 1.7 million acres of new trees |
|
Strategy 6: Plant a tree |
|
|
Adding green to your garden is beautiful and earth-pleasing |
Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year |
1.What is the best title for the passage?
|
A.Strategies to Save Money |
|
B.Ways to be Earth-Friendly |

Is there a limit to the number of years that a person can expect to live? Can changes in life-style add years to one’s life? Throughout history people have sought answers to these questions and others.
Various myths offer the hope of great longevity. In the imaginary land of Shangri-La, for example, people are said to lead a charmed existence for a thousand years. The Spanish explorer Ponce de Leon was convinced that he would find the Foundation of Youth in what is now the state of Florida. According to the Bible, Methuselah lived to be more than 900 years old.
The subject of longevity is fascinating, and scientists study individuals such as Jeanne Calment to learn about the aging process. Calment died in 1997 in Arles, France, at the age of 122. She never married, and she lived in her own apartment until moving to a retirement community when she was 109.
Most scientists agree that bodies will last, at best, about 125 years. This potential has changed little since modern human beings appeared more than 100 thousand years age. Recent improvements in medicine and the environment have extended life expectancy, especially for those from poorer parts of the world. It is not clear, however, whether such improvements will lengthen life expectancy beyond a certain point.
Life expectancy is the number of years an infant can be expected to live, given the conditions into which it is born. Life expectancy, therefore, is affected by nutrition, medical care, and social and political circumstances. An individual’s genetic makeup is also an important factor. Children from long-lived families can hope to enjoy long lives themselves. According to recent data, the average life expectancy worldwide in 1998 was 67 years. This can be compared with an average life expectancy of 77 in the United States.
In 1970 the average life expectancy worldwide was 61 years, or 6 years less than it was in 1998. This same period saw a drop in infant mortality -— the death of a child before the first birthday-—from 80 births out of 1,000 to 54 births out of 1,000. According to some researchers, the rise in the average life expectancy is due primarily to the drop in infant mortality. It is not so much that adults are living to an older age. It is, rather, that more people are living into adulthood because more children are surviving beyond their first birthdays.
1.Infant mortality is defined as ________ .
A. the number of children born alive
B. the kinds of behavior typical of very young children
C. the number of children, out of 1,000 births, who die before their first birthday
D. the typical and obvious thoughts of very young children
2.Although it may be possible to improve the life expectancy of a particular group of people, ________ .
A. it is more difficult to affect the rate of infant mortality
B. it is unlikely that one will be able to extend the potential life span of human beings in general
C. the process of evolution is extending the potential life span beyond 125 years
D. the potential that bodies will last, at best, about 125 years has changed much since modern human beings appeared
3.One can infer that people have at times imagined that ________ .
A. people live longer in the state of Florida
B. a long life is a burden rather than a blessing
C. it is possible to find a way to live for centuries
D. life expectancy is affected by a couple of factors
4.One can conclude that ________ .
A. the aging process can be stopped.
B. the aging process is inevitable.
C. life expectancy in the United States will soon reach 125 years.
D. the average life expectancy worldwide is decreasing

阅读下面短文并回答问题,然后将答案写到答题卡相应的位置上(请注意问题后的词数要求)。
[1] Parents and educators battle over how much homework kids should have, and how often they should have it. This past school year, my eldest daughter's teacher did not assign too much homework, and often gave the kids extra time during class to get it done. Meanwhile, my daughter's dear friend — who attends the same school and is in the same grade — struggled nightly with her lengthy homework assignments. She had work to do every night, extra projects to complete, and assignments to complete over holiday break.
[2] So which was the lucky kid? Some might argue that my child was — she had more time to play, and spent less time stressing over assignments. Others might feel that my child was missing out on a key element of her education by not having what she was learning during the school day reinforced.
[3] To be honest, I'm not really sure which camp I'm in, but it's debates like this one that have sparked a homework revolution between parents and schools all over the country. A New York Times article reported that the school district in Galloway, N.J., is considering a proposal to limit weeknight homework to 10 minutes for each year of school — 20 minutes for second-graders, 30 minutes for third-graders, etc. — and ban assignments on weekends, holidays and school vacations. The school district in Pleasanton, Calif., is looking at a similar proposal. __________, other schools around the country are introducing homework-free holidays, no-homework nights, and goal-work — instead of homework — that can be completed throughout the school day.
[4] Most of these changes are in response to annoyed parents who see lengthy homework assignments competing with what little family time they have each day. The documentary "Race To Nowhere" spurred(激起)more debate by highlighting the unnecessary pressure on kids in today's educational system.

I once had my Chinese MBA students brainstorming on “two-hour business plans”. I separated them into six groups and gave them an example: a restaurant chain. The more original their idea, the better, I said. Finally, five of the six groups presented plans for restaurant chains. The sixth proposed a catering(餐饮) service. Though I admitted the time limit had been difficult, I expressed my disappointment.
My students were middle managers, financial analysts and financiers from state-owned enterprises and global companies. They were not without talent or opinions, but they had been shaped by an educational system that rarely stressed or rewarded critical thinking or inventiveness. The scene I just described came in different forms during my two years’ teaching at the school. Papers were often copied from the Web and the Harvard Business Review. Case study debates were written up and just memorized. Students frequently said that copying is a superior business strategy, better than inventing and creating.
In China, every product you can imagine has been made and sold. But so few well-developed marketing and management minds have been raised that it will be a long time before most people in the world can name a Chinese brand.
With this problem in mind, partnerships with institutions like Yale and MIT have been established. And then there’s the “thousand-talent scheme”: this new government program is intended to improve technological modernization by attracting top foreign-trained scientists to the mainland with big money. But there are worries about China’s research environment. It's hardly known for producing independent thinking and openness, and even big salary offers may not be attractive enough to overcome this.
At last, for China, becoming a major world creator is not just about setting up partnerships with top Western universities. Nor is it about gathering a group of well-educated people and telling them to think creatively. It’s about establishing a rich learning environment for young minds. It’s not that simple.
1.Why does the author feel disappointed at his students?
|
A.Because there is one group presenting a catering service. |
|
B.Because the six groups made projects for restaurant chains. |
|
C.Because all the students copied a case for the difficult topic. |
|
D.Because the students’ ideas were lacking in creativeness. |
2.Which of the following scenes is NOT considered as lack of creation?
|
A.Papers were often downloaded from the Internet. |
|
B.Students often said that copying is a preferable business strategy. |
|
C.Students combine knowledge and critical thoughts to solve a problem. |
|
D.Case study debates were written up as well as recited. |
3.The underlined word “scheme” in the forth paragraph means__________.
|
A.timetable |
B.theme |
C.project |
D.policy |
4.We can infer from the passage that ___________.
|
A.China can make and sell any product all over the world |
|
B.high pay may not solve the problem of China’s research environment |
|
C.cooperation with institutions has been set up to make a Chinese brand |
|
D.the new government program are aimed at encouraging imagination |
5.Which is the best title of the passage?
|
A.Look for a New Way of Learning |
B.Reward Creative Thinking |
|
C.How to Become a Creator |
D.Establish a technical Environment |
