单选题 on the morning of September' 11 th, 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 corner 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{{B}}Directions:{{/B}} There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. All types of stress study, whether under laboratory or real-life situations, study mechanisms for increasing the arousal level of the brain. The brain blood flow studies show that reciting the days of the week and months of the year increases blood flow in appropriate areas, whereas problem solving which demands intense concentration of a reasoning type produces much larger changes in the distribution of blood in the brain. Between these basic studies of brain function and real-life situations there is still a considerable gap, but reasonable deduction seems possible to try and understand what happens to the brain. Life consists of a series of events which may be related to work or to our so-called leisure time. Work may be relatively automatic--as with typing, for instance. It requires intense concentration and repetition during the learning phase to establish a pattern in the brain. Then the typist's fingers automatically move to hit the appropriate keys as she reads the words on the copy. However, when she gets tired she makes mistakes much more frequently. To overcome this she has to raise her level of arousal and concentration but beyond a certain point the automatic is lost and thinking about hitting the keys leads to more mistakes. Other jobs involve intense concentration such as holding bottles of wine up to a strong light and turning them upside down to look for particles of dirt falling down. This sounds quite easy but experience teaches that workers can do this for only about thirty minutes before they start making a mistake. This is partly because the number of occasions with dirt in the bottle is low and the arousal level, therefore, fails. Scientists have shown that devices to raise arousal level will increase the accuracy of looking for relatively rare events. A recent study of the effect of loss of sheep in young doctors showed that in tests involving a challenge to their medical judgment when short of sleep they raised their arousal level and became better at tests of grammatical reasoning as well.

单选题No woman can be too rich or too thin. This saying often attributed to the late Duchess of Windsor embodies much of the odd spirit of our times. Being thin is deemed as such a virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better—or worse—part of my life. Being rich wouldn't be bad either, but that won't happen unless an unknown relative dies suddenly in some distant land, leaving me millions of dollars. Where did we go off the track? When did eating butter become a sin, and a little bit of extra flesh unappealing, if not repellent? All religions have certain days when people refrain from eating, and excessive eating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat—or even only somewhat overweight—is bad because it implies a lack of moral strength. Our obsession with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that, in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem—too much fat and a lack of fiber—than a weight problem. The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually hazardous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall lifestyle. Thinness can be pure vainglory.

单选题Whatever happened to the death of newspaper? A year ago the end seemed near. The recession threatened to remove the advertising and readers that had not already fled to the Internet. Newspapers like the San Francisco Chronicle were chronicling their own doom. America's Federal Trade commission launched a round of talks about how to save newspapers. Should they become charitable corporations? Should the state subsidize them ? It will hold another meeting soon. But the discussions now seem out of date. In much of the world there is the sign of crisis. German and Brazilian papers have shrugged off the recession. Even American newspapers, which inhabit the most troubled come of the global industry, have not only survived but often returned to profit. Not the 20% profit margins that were routine a few years ago, but profit all the same. It has not been much fun. Many papers stayed afloat by pushing journalists overboard. The American Society of News Editors reckons that 13, 500 newsroom jobs have gone since 2007. Readers are paying more for slimmer products. Some papers even had the nerve to refuse delivery to distant suburbs. Yet these desperate measures have proved the right ones and, sadly for many journalists, they can be pushed further. Newspapers are becoming more balanced businesses, with a healthier mix of revenues from readers and advertisers. American papers have long been highly unusual in their reliance on ads. Fully 87% of their revenues came from advertising in 2008, according to the Organization for Economic Cooperation & Development(OECD). In Japan the proportion is 35%. Not surprisingly, Japanese newspapers are much more stable. The whirlwind that swept through newsrooms harmed everybody, but much of the damage has been concentrated in areas where newspaper are least distinctive. Car and film reviewers have gone. So have science and general business reporters. Foreign bureaus have been savagely cut off. Newspapers are less complete as a result. But completeness is no longer a virtue in the newspaper business.
