C
A new age is coming. Call it what you will: the service economy, the information age, the knowledge society. It all translates to a fundamental change in the way we work. Already we’re partly there, the percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the range of the economic transformation can’t be measured by numbers alone, because it also is giving rise to important new way of thinking about the nature of work itself. Long-held ideas about jobs and careers, the skills needed to succeed, even the relation between individuals and employers — all these are being challenged.
We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip, would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more valid, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information service will be superior. It will be the way you do your job.
66. A characteristic of the new age mentioned in the passage is that .
A. the service industry mainly relies on females
B. manufacturing industries are steadily increasing
C. more people are in the service industry than before
D. the work in the service industry is more comfortable than that in manufacturing industry
67. Which of the following is true according to the passage?
A. People’s traditional concepts about jobs need changing.
B. The relation between employees and employers is becoming tense.
C. More women than men are in the work force.
D. Part-time jobs are more welcome than full-time jobs.
68. By mentioning the invention of “the chip”, the author means to say that .
A. we haven’t paid enough attention to the importance of high technology
B. the chip is the most important invention today
C. the power of science and technology is beyond our imagination
D. it’s a great challenge to apply new inventions to our life
69. We may draw a conclusion from the passage that .
A. information will play a greater role in people’s work and daily life in the future
B. we can foresee the future if technology develops fast enough
C. the ability of performing routine tasks gives you an advantage in work
D. robots will replace people to do all the work both in manufacturing and service industries
70. The author’s attitude to the coming age is .
A. doubtful B. enthusiastic C. satisfied D. Uncertain

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
A. what stem cells were B. whether they would grow back
C. how long it would take to re-grow D. how they would re-grow
41. A newt will re-grow its leg if _____.
A. its ankle was cut off but the nerve bundle was good
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle were cut off
42. What do the underlined words “these materials” refer to?
A. Nerve bundles and proteins. B. Proteins similar to n-AG.
C. Stem cells and proteins. D. Stem cells and nerve bundles.
43. The first sentence of the passage _____.
A. acts as a lead–in B. shows where researchers got their new ideas
C. states the author’s opinion D. describes the result of researchers’ studies
