单选题{{B}}Passage 1{{/B}} On the morning of September 11th, I boarded the train from Washington Heights in Upper Manhattan just as usual and went to the Body Positive office in the South Street Seaport of Lower Manhattan. While I was leaving the subway at 8:53 am, a man ran down the street screaming, "Someone just bombed the World Trade Center." Those around me screamed and shouted "No!" in disbelief. However, being an amateur photographer, and thinking that I might be able to help out, I ran directly toward the WTC. I stopped just short of the WTC at a comer and looked up. There before me stood the gaping hole and fire that had taken over the first building. I stood there in shock taking pictures, wanting to run even closer to help out, but I could not move. Soon I saw what looked like little angels floating down from the top of the building. I began to cry when I realized that these " angels" —in fact, desperate office workers--were coming down, some one-by-one, some even holding hands with another. Could I actually be seeing this disaster unfold with hundreds of people around me crying, screaming and running for safety? As I watched in horror, another white airliner came from the south and took aim at the South Tower. As the plane entered the building, there was an explosion and fire and soon debris (碎片) began to fall around me. It was then that I realized that we were being attacked and that this was just not a terrible accident. Yet, I still could not move, until I was pushed down by the crowd on the street, many now in a panic running toward the water, as far from the WTC as they could possibly get. All around me were the visual reminders of hundreds of people running in panic. There were shoes, hats, briefcases, pocketbooks, newspapers, and other personal items dropped as hundreds of people ran for safety. Much has been written about the disaster already. We have learned so much in such a small amount of time about appreciating life. In some way we must move forward, bury the dead, build a memorial for those lost, and begin the coping and healing process for the survivors. But healing takes time. Some have been able to head right back to work, others seek counseling, while others remain, walking through the streets with expressionless faces. However, we are all united in our grief.

单选题What are those of us who have chosen careers in science and engineering able to do about our current problems? First, we can help destroy the false impression that science and engineering have caused the current world trouble. On the contrary, science and engineering have made vast contributions to better living for more people. Second, we can identify the many areas in which science and technology, more considerably used, can be of great service in the future than in the past to improve the quality of life. While we can make many speeches, and pass many laws, the quality of our environment will be improved only through better knowledge and better application of that knowledge. Third, we can recognize that much of the dissatisfaction we suffer today results from our very successes of former years. We have been so greatly successful in attaining material goals that we are deeply dissatisfied that we cannot attain other goals more rapidly. We have achieved a better life for most people, but we are unhappy that we have not spread it to all people. We have reduced many sources of environmental disasters, but we are unhappy that we have not conquered all of them. It is our raised expectations rather than our failures which now cause our distress. Granted that many of our current problems must be cured more by social, political, and economic instruments than science and technology, yet science and technology must still be the tools to make further advances in such things as clean air, clean water, better transportation, better medical care, more adequate welfare programs, purer food, conservation resources, and many other areas.

单选题By education, I mean the influence of the environment upon the individual to produce a permanent change in the habits of behavior, of thought and of attitude. It is in being thus susceptible to the environment that man differs from the animals, and the higher animals from the lower. The lower animals are influenced by the environment but not in the direction of changing their habits. Their instinctive responses are few and fixed by heredity. When transferred to an unnatural situation, such an animal is led astray by its instincts. Thus the "ant-lion" whose instinct implies it to bore into loose sand by pushing backwards with abdomen, goes backwards on a plate of glass as soon as danger threatens, and endeavors, with the utmost exertions to bore into it. It knows no other mode of flight, "or if such a lonely animal is engaged upon a chain of actions and is interrupted, it either goes on vainly with the remaining actions(as useless as cultivating an unsown field)or dies in helpless inactivity". Thus a net-making spider which digs a burrow and rims it with a bastion of gravel and bits of wood, when removed from a half finished home, will not begin again, though it will continue another burrow, even one made with a pencil. Advance in the scale of evolution along such lines as these could only be made by the emergence of creatures with more and more complicated instincts. Such beings we know in the ants and spiders. But another line of advance was destined to open out a much more far-reaching possibility of which we do not see the end perhaps even in man. Habits, instead of being born ready-made(when they are called instincts and not habits at all), were left more and more to the formative influence of the environment, of which the most important factor was the parent who now cared for the young animal during a period of infancy in which vaguer instincts than those of the insects were molded to suit surroundings which might be considerably changed without harm. This means, one might at first imagine, that gradually heredity becomes less and environment more important. But this is hardly the truth and certainly not the whole truth. For although fixed automatic responses like those of the insect-like creatures are no longer inherited, although selection for purification of that sort is no longer going on, yet selection for educability is very definitely still of importance. The ability to acquire habits can be conceivably inherited just as much as can definite responses to narrow situations. Besides, since a mechanism—is now, for the first time, created by which the individual(in contradiction to the species)can be fitted to the environment, the latter becomes, in another sense, less not more important. And finally, less not the higher animals who possess the power of changing their environment by engineering feats and the like, a power possessed to some extent even by the beaver, and preeminently by man. Environment and heredity are in no case exclusive but always-supplementary factors.
