单选题{{B}}Text 3{{/B}} Autonomous robots are able to move and decide by themselves. At a simple level, these can include robot vacuum cleaners that "decide" what to react to human behaviors without human intervention. The University of the West of England's David McGoran takes his Heart Robot on a touchy feely tour, allowing it to come face to face with a spider-like robot built by Matt Denton of Micromagic Systems. Both robots are being displayed at the London Science Museum until July 31st. The heart robot that "enjoys" being hugged and stroked could be among the first robots to signify a new era of "emotional machines" used for medical treatment and enjoyment, according to one of its inventors. It has a beating heart which rises when the body is shaken, but slows down when treated calmly. In addition, Heart's eyes flutter in response to touch. David McGoran, of the University of the West of England, predicts the part-puppet, part-machine creation he helped develop is an example of how robots will increasingly adopt human characteristics. "Right now we're seeing the first implementations in toys, "he told BBC News. "There are little robotic dinosaurs. There's a new robotic toy from the film Wall-E that's coming out, and that's a very expressive robot." Nevertheless he believes there could be major implications for social care, with research already taking place into giving elderly care homes robots that express emotions. "This raises really interesting social and ethical questions," said Mr. McGoran. He added that there could be many benefits, particularly for people taking medical treatment. "If scientists can put this natural interface into robots then it would be much easier for us to relate to robots. " The Heart Robot is on display alongside a face-tracking insect-like robot. The "ic Hexapod" by Micromagic Systems has been programmed to recognize human facial features and follow people as they move around. It tracks human faces and takes photos. Like the Heart Robot, it is billed as an example of the increasingly sophisticated ways in which machines are able to recognize and mimic human behavior.

单选题{{B}}Text 3{{/B}} Sociologists (社会学家) tell us that we are heading for a society leisure. The trend is unmistakable. One hundred years ago, they point out a worker put in twelve or thirteen hours a day, six days a week, and week followed week without an annual vacation. But over the years the picture has changed. Today the typical work week has five eight-hour days, and workers enjoy about three weeks of paid vacation every year, with the result that today me spend less than as much time on the job as people did before. In spite of this, today's worker may not feel that he has a great deal of leisure time. This is because a lot of the non-work time is taken up with fulfilling family and social obligations. For example, he feels that he should spend some time with his children every day, and if a man does physical activity in his job, that too cuts into his free time. Nevertheless, the final result is that we do have more leisure-more time free from the obligation of work or any other social requirement. Leisure is time not used to earn money or to do things around the house which save money. It is time spent only in seeking satisfaction, and we give up what we are doing when it no longer satisfies us. Leisure gives us the opportunity to recover from the physical and mental fatigue (疲倦) of work and it frees our creative talents from the pressure placed on us by the job. Today's leisure is time programmed for doing what you want to. It does not have to be made up the next day. This is something new. It really frees a person from the workshop to enjoy, for a time, things in which he is interested. Man is about to go out to the playground.

单选题In the earliest stages of man's development he had no more need of money than animals. He was content with very simple forms of shelter, made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him. As he became more civilized, however, he began to want better shelter, more efficient tools and weapons, and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands. For these things he had to turn to the skilled people Such as smiths, leather workers or carpenters who were springing up everywhere. It was then that the question of payment arose. At first he got what he wanted by a simple process of exchange. The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer in exchange for an axe or a plough. But as more and more goods which had no fixed exchange value came on the market, exchange became too complicated to be satisfactory. Another problem arose when those who made things wanted to get stocks of wood or leather, or iron, but had nothing to offer in exchange until their finished goods were ready. Thus the difficulties of exchange led by degrees to the invention of money. In some countries, easily handled things like seeds or shells were given a certain value and the farmers, instead of paying the smith for a new axe by giving him some meat or grain, gave him so many shells. If the smith had any shells left when he had bought his food, he could get stocks of the raw materials of his trade. In some countries quite large things such as cows or camels or even big flat stones were used for trade. Later, pieces of metal, bearing values according to the rarity of the metal and the size of the pieces, or coins were used. Money as we know it had arrived.

单选题{{B}}Text 2{{/B}} "Hi there. How's it going?" "Oh, fine, fine. How about this weather, huh?" "Well, I guess we can always use the rain." What's that? This story? Oh, just a little look at small talk. You know, those seemingly meaningless conversations you have dozens of times a day. Maybe you're waiting for the elevator. Or in a line at the bank. It all seems pretty trivial. Idle chatter about traffic doesn't do much more than fill the air with empty words that are quickly forgotten. But you should know that small talk actually has a big place in our lives. Pat Oliver, assistant professor on arts, says that, "Left unchecked, small talk can be an invasion. It's so powerful. It does something to you." "Every morning after spending an hour and a half on the freeway I start the day with small talk with my secretary," Oliver says, "If I don't make small connection with another person, I can't work." What causes it? As a rule, you're either trying to force something into your life, or you're using conversation as an invisible force field to keep them out. You can be wanting to connect with another person, and small talk is your introduction to more meaningful conversation. The way people use small talk is usually determined by where they happen to be at the time. Take the elevator, for instance. Now there's prime territory. Nobody knows anyone and there's no reason to start a conversation, but invariably, someone does. Making conversation in such peaceful social settings, according to Oliver, "can confirm your territory. It's a way of feeling liked and accepted." The topics of small talk don't matter. In fact, you don't want anything more taxing than the weather or the traffic. It's non-threatening talk in a threatening situation. However, the rules change quickly when you're with lots of people doing lots of talking. Let's say you're at a party. Now it's time to use small talk as a way of making others feel more comfortable around you, so you don't look silly standing by the food table alone all night.
