say they will have made it by the year 2020.Carol Packer repots. Machines that walk，speak and feel are no longer science fiction.Kismet is the name of an android(机器人)which scientists have built at the Massachusetts Institute of Technology(MIT).Kismet is different from the tradition。al robot because it can show human emotions.Its eyes.ears and lips move to show when it feels happy.sad or bored.Kismet is one of the first of a new generation of androids—robots that 100k like human beings—which can imitate human feelings.Cog，another android invented by the MIT, imitates the action of a mother However,scientists admit that so far Cog has the mental ability of a two year old. The optimists(乐观主义者)say that by the year 2020 we will have created humanoids(机器人)with brains similar to those of an adult human being.These robots will be designed to look like people to make them more attractive and easier to sell to the public.What kind of jobs will they do？ In the future，robots like Robonaut ，a humanoid invented by NASA，will be doing dangerous jobs，like repairing space stations They will also be doing more and more of the household work for US.In Japan，scientists are designing androids that will entertain US by dancing and playing the piano. Some people worry about what the future holds：will robots become monsters(怪物)？Will people themselves become increasingly like robots？ Experts predict that more and more people will be wearing micro-computers，connected to the Internet，in the future.People will have micro-chips in various parts of their body，which will connect them to a wide variety of gadgets(小装置).Perhaps we should not exaggerate(夸大)the importance of technology，but one wonders whether , in years to come，we will still be falling in love，and whether we will still feel pain.Who knows？ 第11题：Kismet is different from traditional robots because A．it thinks for itself B．it is not 1ike science fiction C．it Can 100k after two-year—olds D．it seems to have human feelings

E.J. Masicampo and Roy Baumeister of Florida State University discovered this by doing some experiments on that most popular of laboratory animals, the impoverished undergraduate. They asked 121 psychology students who had volunteered for the experiment to watch a silent video of a woman being interviewed that had random words appearing in bold black letters every ten seconds along the perimeter of the video. This was the part of the experiment intended to be mentally taxing. Half of the students were told to focus on the woman, to try to understand what she was saying, and to ignore the words along the perimeter. The other half were given no instructions. Those that had to focus were exerting considerable serf-control not to look at the random words. When the video was over, haft of each group was given a glass of lemonade with sugar in it and half was given a glass of lemonade with sugar substitute. Twelve minutes later, when the glucose from the lemonade with sugar in it had had time to enter the students' blood, the researchers administered a decision-making task that was designed to determine if the participant was using intuition or reason to make up his mind. The students were asked to think about where they wanted to live in the coming year and given three accommodation options that varied both in size and distance from the university campus. Two of the options were good, but in different ways: one was far from the campus, but very large; the other was close to campus, but smaller. The third option was a decoy, similar to ope of the good options, but obviously not quite as good. ff it was close to campus and small, it was not quite as close as the good close option and slightly smaller, if it was far from campus and large, it was slightly smaller than the good large option and slightly farther away. Psychologists have known for a long time that having a decoy option in a decision-making task draws people to choose a reasonable option that is similar to the decoy. Dr. Masicampo and Dr. Baumeister suspected that students who had been asked to work hard during the video and then been given a drink without any sugar in it would be more likely to rely on intuition when making this decision than those from the other three groups. And that is what happened; 64% of them were swayed by the decoy. Those who had either not had to exert mental energy during the showing of the video or had been given glucose in their lemonade, used mason in their decision-making task and were less likely to be swayed by the decoy. It is not clear why intuition is independent of glucose. It could be that humans inherited a default nervous system from other mammals that was similar to intuition, and that could make snap decisions about whether to fight or flee regardless of how much glucose was in the body. Whatever the reason, the upshot seems to be that thinking is, indeed, hard work. And important decisions should not be made on an empty stomach. The word "taxing" in the fast paragraph means A．tiring. B．imposing taxation. C．paying taxation. D．relaxing.

A．brief B．precise C．simplified D．extensive

The only solid piece of scientific truth abut which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th. century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can' t be answered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention. According to the author, really good science ______. A．would surprise the brightest minds of the 18th century Enlightenment B．will help people to make the right choice in advance C．will produce results which cannot be foreseen D．will bring about disturbing results

A．ingredient B．reliance C．shelter D．inclination
