Brain Transplants

Research on the human brain has been attracting more and more scientists in recent years.   71   If we compare a human brain to a hard disc, what the scientists are doing is to make better use of the hard disc.

The idea that a human brain could be transplanted (移植) may come from Frankenstein. In 1999, an experiment turned a bear into a dolphin (海豚).   72   They were made of the memory area in the dolphin’s brain containing information about swimming. They had a series of useful information, which was saved into a button – sized chip (芯片). Later the information was transplanted into the action memory area in the bear’s brain.   73   It proved to be a highly successful experiment and a bear was turned into a dolphin.

Recently, another memory transplant was performed at the Motor Nerve Rescarch Instance of the University of California. The experiment bad an entire transplant of the memory area.   74   The transplant was performed from a dog named Cenius to a dog named idiot. Cenius could follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. However, Idiot had no contact with people since its birth. It because an animal with nothing in its brain, without any memory.

  75   When the two dogs woke up, Idiot had grasped all the abilities Cenius possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But Cenius gave no response to its master, and did not recognize him at all.

       A．The experiment was a complete success.

       B．It included actions, moods, logic, words, images, etc.

       C．Then it was released (释放) by means of electric power.

       D．Different images have different meanings in the memory area.

       E．Using the most advanced technology, detailed images were produced.

       F．Discoveries show that messages are carried by the central nervous system in the brain.

       G．One of the latest topics is how to change the human brain or combine it with the computer.

Are you a team person? Are you at your best as part of a small, tightly united group of dedicated workers? If so, the future may hold more for you than you think.

   1.    That’s happening in those areas of business and data processing where one person and a computer can replace a team of workers.

2.  High technology has led to a new type of teamwork in a number of fields, including advertising, scientific research, engineering design, architecture and ocean exploration.

Through computer networking, scientists, engineers, and technicians at different locations — often thousands of miles apart --- can work on the same project at once.    3.    

Examples? An engineering team can now design and try out a robot system --- a new manufacturing process, or an entire factory — before it is built. An architectural team can do the same with a building or a bridge. A medical team can simulate a dangerous operation before performing it on a patient.

Of course, computer-assisted team effort doesn’t end with investigation and simulation.  4.  “CAD-CAM --- computer-aided design and manufacture --- is breaking down barriers between traditional design and manufacturing functions.” explains Dr. Prakash Rao, an engineering manager at General Electric. “Interdisciplinary(跨学科的) teams and engineers follow a product from concept to production. Everything is interconnected like a network.”

5.   A team that produces robots may use them to explore space and ocean depths. For high-technology teamwork, the future seems limitless.

A. They can exchange ideas, try out different designs, and test their results.

B. It now usually continues into actual design, manufacturing, and testing.

C. In the future, team work will be highlighted by the introduction of new technology.

D. Sometimes, a computer-aided effort can extend beyond production.

E. But, elsewhere, teamwork is very much alive.

F. It ends in the products which are extensions of the traditional design.

G. High technology, some predicted, would make team work a thing of the past.

Why do some people have many friends while others do not?   1.  However, it is not so. Let’s look at two psychological experiments which will give you the key to happy interpersonal relations.

The first experiment is called the “Hawthorne effect” after Hawthorne, Illinois, where the experiment took place. A group of psychologists examined the work patterns of two groups of workers in the Western Electric Company.   2.  The psychologists changed the working conditions for one group twice but left the other group alone. They were surprised to find that productivity increased on both occasions and in both groups. They concluded that the increase in productivity came from the attention given to the workers by the management. It had increased their motivation and so they had worked harder. In other words, if you take an interest in others, they will want to please you and you will have good relations with them.

 3.  After Martin Luther King, Jr was killed in 1960s, a teacher, Jane Elliott, living in an all-white town decided to help her class of young children understand why the Civil Rights Movement had been necessary in America.

She divided the class into two groups: one with blue eyes and other with brown eyes. Other eye colors such as hazel or green were excluded from his exercise. Then she told the class that brown-eyed people were cleverer than blue-eyed ones because of an agent for brown color found in their blood. Blue-eyed people were stupid, lazy and not to be trusted. Jane Elliott did not need to say any more. The brown-eyed students quickly got used to their new role as the leaders of the class. The blue-eyed students became quiet and withdrawn. Then she discovered something very interesting. Four poor brown-eyed readers began to read fluently in a way they had never done before.  4.  So if you want to be successful and happy, take an interest in others whether they are your classmates or workmates. Congratulate them on their success and sympathize with them in their troubles. 5. 

A．Before the experiment the management talked to both groups of workers and explained that they wanted to find the best working environment for them.

B．Remember that the way you treat others will decide their attitude and behavior to you.

C．The second experiment shows what happens to personal relations if you are rude to or ignore others.

D．The ones who have more friends usually are those who care about others.

E. Jane Elliott had shown that the way people are treated affects not only their behavior but also their confidence and their performance.

F. You may even imagine that this ability was something they were born with because it seems so effortless to them.

G. The second experiment tells us what teachers said had a great effect on the students.

Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas.  1  

Most Americans would find it hard to imagine what life would look like without cars. 2 . The polluted air becomes poisonous and dangerous to health.

 3 . That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else.  4 . Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down.  5 .

Although cars have led us to a better life, they have also brought us new problems.

A．Thus the problem of air pollution would become less important than that of unemployment.

B．Americans know cars very well.

C．However, some have realized the serious problems of the air pollution that is caused by cars.

D．One way to get rid of the polluted air is to build a car that does not pollute.

E. However, the number of vehicles has continued to increase in recent years.

F. Americans won’t live without cars!

G. Inventors are now working on steam cars as well as electric cars.
