Most people would agree that it would be wonderful if humans could regenerate (再生) limbs. Those who have lost their arms or legs would be complete again. The day is still far off when this might happen. But in the last 10 years, doctors have reported regeneration in smaller parts of the body, most often fingers.
Regeneration is not a newly-discovered process. For centuries, scientists have seen it work in some kinds of animals. Scientists now are looking for a way to turn on this exciting ability in more highly-developed animals, including humans. Their experiments show that nerves (神经), cell chemistry and the natural electric currents in the body all seem to have a part in this process.
The body of every animal contains general purpose cells that change into whatever kind of cells the body needs. These cells collect around the wound. They form a mass called a blastema (芽基). The cells of the blastema begin to change. Some became bone cells, some muscle cells, some skin cells. Slowly, a new part re-grows from the body outward. When completed, the new part is just like the old one.
More than 200 years ago, Italian scientist Luigi Spallanzani showed that younger animals have a greater ability to regenerate lost parts than older animals. So do animals lower on the ladder of evolutionary (进化的) development. The major differences seem to be that less-developed animals have more nerves in their tails and legs than humans do in their arms and legs.
Another helpful piece of information was discovered in the late 1800s. Scientists found that when a creature is injured, an electrical current flows around the wound. The strength of the current depends on how severe the wound is and on how much nerve tissue (组织) is present.

TOKYO—A child-like robot that combines the roles of nurse, companion and security guard is to go on the market to help the growing ranks of elderly Japanese with no one to look after them.
The “Wakamaru” robot can walk around a house 24 hours a day, warning family, hospitals and security firms if it perceives (notices) a problem. It will, for example, call relatives if the owner fails to get out of the bath.
Cameras implanted in the “eye-brows” of the robot enable it to “see” as it walks around an apartment. The images can be sent to the latest cellphones, which display the pictures.
Mitsubishi Heavy Industries, which developed Wakamaru, plans to start selling the metre-high robots by April, 2005, for about ＄15,000 Cdn.
Wakamaru, which speaks with either the voice of a boy or girl, is also designed to provide companionship, greeting its “papa” when he comes home.
It is the first household robot able to hold simple conversations, based on a vocabulary of around 10,000 words. It cannot only speak but can understand answers and react accordingly.
It will ask “Are you all right ?” if its owner does not move for some time. If the answer is no, or there is no answer, it will telephone preset numbers, transmitting images and functioning as a speakerphone.
Wakamaru will inform a security firm if there is a loud bang or if an unknown person enters the house while the owner is out or asleep. It can recognize up to 10 faces.
But like most robots it cannot climb stairs.
It can be set to remind forgetful people when it is time to take medicine, eat and sleep.
Mitsubishi adapted Wakamaru from robots it already makes to go around nuclear power facilities. The idea to use the technology in the home came from a company employee.
The project chief said :“Looking at the ageing of society and the falling birth rate we decide that this could work as a business. We want to offer Wakamaru as a product that helps society.”
The technology has gained nation-wide publicity in Japan among increasing concern over how to look after the ever-growing number of old people. The life expectancy of Japanese women has shot up to almost 85, the highest in the world.
At the same time, extended families are being replaced by nuclear families. This has left many Japanese anxious about their elderly parents, whom they rarely see because of their long hours at the office.

With many college graduates struggling to find jobs, one of the most important for you to understand is that you're in school all your life. In fact, your real education is just beginning.
I'd like to pass on a few lessons that you didn't necessarily get in school. If you've been out of school for a few years or a lot of years, they could still teach you something.
· Develop relationships and keep networking, if I had to name a single characteristic shared by all the truly successful people I've met, I'd say it is the ability to create and nurture (培育) networks of contacts. Start strengthening your relationships now, so that they'll be in place when you really need them later. In the classroom it was mostly about individual performance. Success in real life requires relationships.
· Set goals. Ask any winner what the key to his or her success was, and you'll hear four consistent messages: vision, determination, persistence, and setting goals. If you don't set goals and determine where you're going, how will you know when you get there? Goals give you more than a reason to get up in the morning; they are an incentive (激励)to keep you going all day.
· Sense of humor. I'm a firm believer in using humor, though not necessarily jokes. A good sense of humor helps one understand the unconventional(非传统的), tolerate the unpleasant, and overcome the unexpected. There are plenty of times to be serious, but I believe that keeping things light and comfortable encourages better teamwork.
· Volunteer. It might be hard to do a lot of volunteer work at first, but people who help others on a regular basis have a healthier outlook on life.

After years of hearing drivers complain about scratches (划痕) on their cars, Japan's Nissan Motor Company has officially announced the next big thing--a paint that not only resists scratches and scrapes, but actually repairs itself within a few days.
The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin (弹性树脂) that is able to heal minor (较小的) marks caused by car wash equipment, parking lot encounters, road debris (石头碎片) or even on-purpose destruction.
The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works.
Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace (痕迹) that they were ever there.
The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period.
Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents.
But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 US to the price of a car.
It plans to use its new chemical mixture only on its X-Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores, as well.
63. From the article, we can find that_______.
A. the paint has already been used on cars by now
B. it beats other products of its kind in its lengthy effect
C. car damage is mainly caused by scratches and scrapes
D. marketing this paint in Europe is not under way
64. The paint used on cars can_________.
A. last 3 years before it is re-applied again
B. fade only in a few days
C. help to protect cars from minor paint damage
D. reduce car scrape incidents to 20 percent
65. What does the underlined part refer to?
A. Certain models of Nissan.
B. Name for one kind of paint.
C. Somewhere in Japan.
D. A word standing for a car-dealer store.
66. What can be inferred from the article?
A. The paint was developed by Nissan Motor Company.
B. The paint might work better in summer than in winter.
C. The mark on the car could disappear as soon as the paint is applied.
D. The paint is very popular in Japan.

We often focus on building relationships with others so that we forget the essential first step: being friends of ourselves. That is the crucial first step if we are to have good relationships with others. How can we have good relationships with others if we don't even have good relationship with ourselves? The problem might be worse than we expect. Maybe we don't like ourselves without realizing it.
For example, maybe you have made mistakes in the past which you feel bad about. You might be disappointed with yourself on why you could make such mistakes. Even if that happened in distant past, your subconscious (潜意识) mind still has a reason not to like yourself.
You might wish that you were born in different family, or that you have different background. Maybe you could not accept the fact that you are not as lucky as others, who seem to get whatever they want effortlessly because of their background.
You might have some personal traits that you don't like. For example, you may be an introvert ( 内向的人) and you don't like it; you wish you are an extrovert (外向的人).
Your achievements relate to others. They might have better achievements than you, and no matter how hard you tried, it might seem impossible for you to match them. You might then think that it's because you are not smart enough or don't have enough talents.
Is there anything that resonates (产生共鸣) with you? All these give reasons to you not to like yourself. That in turn makes it difficult for you to be a good friend to yourself.
Fortunately, there are always things you can do to fix the situation. Here are some tips:
1. Forgive yourself.
2. Accept things you can't change.
3. Focus on your strengths.
4. Write your success stories.
5. Stop comparing yourself with others.
6. Always be true to yourself.

A. Resonating is very important for making friends.
B. How to make friends with ourselves is very difficult.
C. Writing your success contributes to stopping comparing with others.
