The next big breakthrough in artificial intelligence could come from giving machines not just more logical capacity, but emotional capacity as well.
Feelings aren't usually associated with inanimate machines, but Rosalind Picard, a professor of computer technology at MIT, believes emotion may be just the thing computers need to work effectively. Computers need artificial emotion to understand their human users better and to achieve self-analysis and self-improvement.
The more scientists study the "wetware" model for computing—the human brain and nervous system—the more they conclude that emotions are a part of intelligence, not separate from it. Emotions are among the tools that we use to process the tremendous amount of stimuli in our environment. They also pay a role in human learning and decision making. Feeling bad about a wrong decision, for instance, focuses attention on avoiding future error. A feeling of pleasure, on the other hand, positively reinforces an experience.
"If we want computers to be genuinely intelligent, to adapt to us, and to interact naturally with us, then they will need the ability to recognize and express emotions, to have emotions, and to have what has come to be called 'emotional intelligence,'" Picard says.
One way that emotions can help computers, she suggests, is by helping keep them from crashing. Today's computers produce error messages, but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense. A healthy fear of death could motivate a computer to stop trouble as soon as it starts. On the other hand, self-preservation would need to be subordinate to service to humans. It was fear of its own death that prompted HAL, the fictional computer in the film 2002: A Space Odyssey, to kill most of its human associates.
Similarly, computers that could "read" their users would accumulate a store of highly personal information about us—not just what we said and did, but what we likely thought and felt.
"Emotions not only contribute to a richer quality of interaction, but they directly impact a person's ability to interact in an intelligent way," Picard says. "Emotional skills, especially the ability to recognize and express emotions, are essential for natural communication with humans."
In the future computers will tend to be made ______.
A．fictional
B．humanized
C．economical
D．operational

Steven and Mary took a taxi to the station. They got out and Steven picked up the heavy suitcase. They could not find a porter, but a young man offered to help them with the case.
"Where are you going？" he asked.

In many stories on TV and in science-fiction books, men travel to faraway stars. They have quick, easy journeys. But so far, men have been able to reach only the earth’s own moon.
Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to move faster than the speed of the light. Nothing can move that fast except light itself.
Strange things happen to an object when it moves rapidly. The object weighs more. An object moving at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A clock runs more slowly. A man would not age so fast as he would on the earth.
Light travels more than 186,000 miles a second, or about 11 million miles a minute. In one year, light travels six trillion miles. That great distance is called a light-year. It is used to measure distance in space.
The star closest to our sun is Alpha Centauri. It is more than four light-years away. If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星) in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years
1．In this passage the words “closest to our sun” means the star（）.
A、the earth we live on
B、Alpha Centauri
C、the Big Dipper
D、the moon
2．A one-way journey to Alcaid would take（）.
A、about nine years
B、less than four years
C、almost 200 years
D、less than 100 years
3．Why do we measure the distance in light-years instead of miles?（）
A、Units of light-years sound better.
B、Using light- years reduced the number of figures used.
C、We used to measure distance in light-years long ago.
D、We do not make mistakes when we use light-years.
4．If a stone moved at the speed of light, it（）.
A、would weigh twice more than it is motionless
B、would weigh as much as it is on earth
C、would weigh less than it is on earth
D、would not have weight at all
5．This story is mainly about （）.
A、the distance between the sun and the other stars
B、the problems of traveling to faraway stars
C、what happens when we travel faster than the speed of light
D、the tool we use when we go to faraway stars

You probably have a long mental list of moments and facts you wish you could remember—but actually you cannot. The good news,【B1】______, is that while such memories may be currently【B2】______, they are not entirely gone, and could theoretically be【B3】______, according to a new brain research. In the study, biologist Jeffrey Johnson【B4】______16 college participants through an FMRI machine (which【B5】______nervous activity via blood flow)to compare brain patterns【B6】______memory formation and recall. First, he showed the students various common words and had them【B7】______a few tasks: say the word backwards in your head,【B8】______its uses, and picture how an artist would【B9】______it. Then, 20 minutes later, after the students re-entered the FMRI machine, Johnson showed them the list of words and asked them to recall【B10】______they could from before. Finally, he compared brain activity from both【B11】______and what he found will surprise you.

阅读文章，回答下列各题： As we know, if we want to keep our healthy and have a strong body, our eating habits are very important in our daily life. There are times when most of us would rather eat sweets and ice cream than meat and rice. Actually, sweets and ice cream are not bad for the stomach if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite. Meanwhile, it is important for us to eat our meal at the same time each day. When we feel hungry, it shows that our bodies need food. When we feel angry or excited, we may not want to eat. When we are worded, we may not want to, eat, either. A long time ago, in England, some judges used to decide whether, a man was telling the truth by giving him some dry bread. If the man could not swallow the bread, it was a sign that he wasn' t telling the troth. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth. A man who is worrying about something has difficulty in swallowing anything dry. He loses his appetite and does not want to eat anything if he is worrying something. We have to develop good ,eating habits because__________
A. we want to be healthy and strong
B. we want to enjoy our food
C. we want to eat more
D. we want to save time

第10题
My wife and I spent two weeks in London last year. We went there in autumn. We think it is the best season to visit England. The weather is usually quite pleasant and there aren't too many tourists in October.
We stayed in a small hotel in the West End. It was convenient as we did most of our sight seeing on foot. Taxis were too expensive; the bus routes were too difficult for us to understand; and my wife didn't like traveling by underground. She said it made her feel shut in.
We went to look at the places, which all tourists see. We saw Buckingham Palace, the National Gallery and Piccadilly Circus. We went shopping in Oxford Street and spent too much money. What we liked most, though, was going to the theatre. We don't have the chance to see such wonderful plays at home. A lot of people say English food is very bad. We didn't think so. It's true that most of the restaurants are French or Italian or Chinese, but we had some very good meals.
In fact, we enjoyed our holiday so much that we have booked another trip to England for this year. We're going to take our umbrellas, though. I'm sure we'll need them.
1)、While in London, the writer and his wife usually got around on foot.
A.T
B.F
2)、The wife didn't like traveling by underground because it was not fast enough.

3)、They could visit good museums in London that they have no chance of doing at home.

4)、In London it is not easy for people to find English restaurants.
A.T
B.F
5)、They are going to take their umbrellas because it often rains in London.
