单选题I don"t ever want to talk about being a woman scientist again. There was a time in my life when people asked constantly for stories about what it"s like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-time and the nature of black holes. At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement—jobs, research papers, awards—was viewed through the lens of gender politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus right brain, or nature versus nurture, 1 would instantly fight fiercely on my behalf and all womankind. Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations: I don"t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn"t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don"t study sociology or political theory. Today I research and teach at Barnard, a women"s college in New York City. Recently, someone asked me how may of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don"t dismiss those concerns. Still, I don"t tell them "war" stories. Instead, I have given them this：the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that"s a sight worth talking about.

单选题I had been working in the trauma unit at a local hospital for about a year. You get used to families thinking that a "coma" patient is moving their hand or doing something that they were asked to do. "Following commands" is what we call it. Often it"s "wishful thinking" on the families" part. Nurses can easily become callous to it. On this particular night during visiting hours, my patient"s wife came in. I had taken care of him for several nights. I was very familiar with his care and what he was able to do. Actually, he didn"t do anything. He barely moved at all, even when something would obviously hurt him, such as suctioning. His wife was very short, about 5 feet tall. She had to stand on a stool to lean over him, so that she could see his face and talk to him. She climbed up on the stool. I spoke to her for a few minutes, and then stepped out to tend to my other patient. A few minutes later, she came running out of the room. In an excited voice, she said, "Donna, he"s moving his hand!" I immediately thought that it was probably her imagination, and that he had not actually done it on purpose. He had been there about a month at the time and had never made any movements on purpose. I asked her what had happened and she said, "I asked him to squeeze my hand and he did!" This led me to another train of questioning. "But, did he let go when you asked him to?" She said yes, that he had done exactly what she asked. I went into the room with her, not really believing that I would see anything different than I had always seen. But I decided that it would be better to pacify her than to make her think I didn"t believe her or that she was somehow mistaken. She asked him to squeeze her hand, which he did. I said, "Well, ask him to let go." He continued to squeeze for a moment, so that when he finally did let go, I really still didn"t believe that he had done it on purpose. So, I said, "Ask him to hold up one finger." He did as asked. Well, this was starting to get my attention. I looked at him, his face still somewhat swollen and his eyes still closed. "Stick out your tongue!" I said. He did it. I almost fell on the floor. It was the first time I had ever seen anyone "wake up".

单选题Graduate school and college are similar ______ you have to choose a field of study and do research.

单选题You can"t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names 1 they feel unhappy about them. However, some people do 2 this course of action—particularly artists! What makes an artist want to change their name? Sometimes it"s for purely 3 reasons, such as the Nobel Prize winning poet from Chile, Neflali Reyes. He didn"t want his father to 4 he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. 5 other times the reason may appear strange; take the case of the Portuguese poet Femando Pessoa, 6 wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, 7 , people change their names, for social, historical, political, or cultural reasons. Here are some of the most 8 . The person"s real name is just 9 long and difficult to remember. Let"s be honest, Madonna Louise Ciccone is not as 10 to remember as just plain "Madonna". And short names are much easier to remember: William Bradley became Brad Pitt and Edson Arantes do Nascimento became Pele.

单选题The media can impact current events. As a graduate student at Berkeley in the 1960s, I remember experiencing the events related to the People's Park that were occurring on campus. Some of these events were given national media coverage in the press and on TV. I found it interesting to compare my impression of what was going on with perceptions obtained from the news media. I could begin to see events of that time feed on news coverage. This also provided me with some healthy insights into the distinctions between these realities. Electronic media are having a greater impact on the people's lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to a global village, or what one writer calls the electronic city. Consider the information that television brings into your home every day. Consider also the contact you have with others simply by using telephone. These media extend your consciousness and your contact. For example, the video coverage of the 1989 San Francisco earthquake focused on "live action" such as the fires or the rescue efforts. This gave the viewer the impression of total disaster. Television coverage of the Iraqi War also developed an immediacy. CNN reported events as they happened. This coverage was distributed worldwide. Although most people were far away from these events, they developed some perception of these realities. In 1992, many people watched in horror as riots broke out on a sad Wednesday evening in Los Angeles, seemingly fed by video coverage from helicopters. This event was triggered by the verdict (裁定) in the Rodney King beating. We are now in an age where the public can have access to information that enables it to make its own judgements, and most people, who had seen the video of this beating, could not understand how the jury (陪审团) was able to acquit (宣布……无罪) the policemen involved. Media coverage of events as they occur also provides powerful feedback that influences events. This can have harmful results, as it seemed on that Wednesday night in Los Angeles. By Friday night the public got to see Rodney King on television pleading, "Can we all get along?" By Saturday, television seemed to provide positive feedback as the Los Angeles riot turned out into a rally for peace. The television showed thousands of people marching with banners and cleaning tools. Because of that, many more people turned out to join the peaceful event they saw unfolding on television. The real healing, of course, will take much longer, but electronic media will continue to be a part of that process.

单选题What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a special-purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated or manual driven cars. A special-purpose 1ane system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway (高速公路) capacity. Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system way was in place, automated driving could begin whenever the driver was on suitably equipped roads. If special-purpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special onramp (入口引道). As the driver approached the point of entry for the highway, devices installed on the roadside would electronically check the vehicle to determine its destination and to ascertain that it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this case, the transition from manual to automated control would take place on the entrance ramp. An alternative technique could employ conventional lanes, which would be shared by automated and regular vehicles. The driver would steer onto the highway and move in normal fashion to a "transition" lane. The vehicle would then shift under computer control onto a lane reserved for automated traffic. [The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers (非法进入者) could be swiftly identified by authorities. ] Either approach to joining a lane of automated traffic would harmonize the movement of newly entering vehicles with those already traveling. Automatic control here should allow for smooth merging without the usual uncertainties and potential for accidents. And once a vehicle had settled into automated travel, the driver would be free to release the wheel, open the morning paper or just relax.
