单选题An orator, whose purpose is to persuade men, must speak the things they wish to hear, an orator, whose purpose is to move men, must also avoid disturbing the emotional effect by any obtrusion of intellectual antagonism, but an author, whose purpose is to instruct men, who appeals to the intellect, must be careless of their opinions and think only of truth. It will often be a question when a man is or is not wise in advancing an unpalatable opinion, or in preaching heresies. But it can never be a question that a man should be silent if unprepared to speak the truth as be conceives it. Deference to popular opinion is one great source of bad writing and is all the more disastrous because the deference is paid to some purely hypothetical requirement. When a man fails to see the truth of certain generally accepted views, there is no law compelling him to provoke animosity by announcing his dissent. He may be excused if he shrink from the lurid glory of martyrdom. He may be justified in not placing himself in a position of singularity. He may even be commended for not helping to perplex mankind with doubts which he feels to be founded on limited and possibly erroneous investigation. But if allegiance to truth lays no stern command upon him to speak out his immature dissent, it does lay a stern command not to speak out hypocritical assent. There are many justifications of silence, there can be none of insincerity.

单选题When it comes to the slowing economy, Ellen Spero isn't biting her nails just yet. But the 47-yearold manicurist isn't cutting, filling or polishing as many nails as she'd like to, either. Most of her clients spend ＄12 to ＄50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I'm a good economic indicator," she says. "I provide a service that people can do without when they're concerned about saving some dollars." So Spero is downscaling, shopping at middle-brow Dillard's department store near her suburban Cleveland home, instead of Neiman Marcus. "I don't know if other clients are going to abandon me, too" she says. Even before Alan Greenspan's admission that America's red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year's pace. But don't sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economy's long-term prospects, even as they do some modest belt-tightening. Consumers say they're not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "there's a new gold rush happening in the ＄4 million to ＄10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks sec silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan's hot new Alain Ducasse restaurant used to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

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There was (a pause of) complete stillness (which) the (buzzing) of the bees among the pink roses sounded (as loud as) the fight of an aircraft.

单选题The narrator in the story said: "I have to meet him!" because ______.

单选题{{B}}Passage Four{{/B}} A mysterious phenomenon is the ability of over-water migrants to travel on course. Birds, bees, and other species can keep track of time without any sensory cues from the outside world, and such "biological clocks" clearly contribute to their "compass sense." For example, they can use the position of the Sun or stars, along with the time of day, to find north. But compass sense alone cannot explain how birds navigate the ocean: after a flock traveling east is blown far south by a storm, it will assume the proper northeasterly course to compensate. Perhaps, some scientists thought, migrants determine their geographic position on the Earth by celestial navigation, almost as human navigators use stars and planets, but this would demand of the animals a fantastic map sense. Researchers now know that some species have a magnetic sense, which might allow migrants to determine their geographic location by detecting variations in the strength of the Earth's magnetic field.

单选题Unfortunately most of the science fiction films of the 1970s were not much influenced by 2001 A Space Odyssey. Skillfully directed by Stanley Kubrick, 2001. which appeared in 1968, set new standards for science fiction films. During the next decade, every one of the dozens of science fiction movies released was compared to 2001 , and all but a few were found sadly lacking. Admittedly, Kubrick had one of the largest budgets ever for a film of this kind, but, in my opinion, much of the movie's power and appeal was achieved through relatively inexpensive means. For example, the musical score, which was adapted in large part from well-known classical compositions, was reinforced by the use of almost kaleidoscopic visual effects, especially during the space travel sequences. Spectacular camera work was edited to correspond precisely to the ebb and flow of the music. After 2001, the dominant theme of science fiction films shifted from the adventures of space travel to the problems created on earth by man's mismanagement of the natural environment and the abuse of technology by a totalitarian state. Overpopulation and the accompanying' shortages of food prompt the state to impose extraordinary controls on its citizens. No fewer than twenty-nine films were made around this theme in the years between 1970 and 1977, including Survivors and Chronicles. In the opinion of this reviewer, until Star Wars was released in 1977, science fiction films were reduced to shallow symbolism disguising to a greater or lesser degree a series of repetitive plots. But Star Wars was different. It offered us a return to imaginative voyages in space and confrontation with intelligent life on other planets. Unlike the other science fiction films of the decade, Star Wars presented technology as having solved rather than aggravated ecological problems. The special effects created to simulate space vehicles hurtling through the blackness of the universe were reminiscent of the artistic standards set by 2001.

单选题For anyone who has experienced an earthquake, the experience can be frightening and traumatic. In addition of the movement of the ground, people need to concerned with collapsing buildings and falling debris, such as flying glass. The majority of the injuries and death that occur from the earthquakes are due to falling objects and structures. The effect of an earthquake can also cause dangerous landslides, fires, gas line explosions and flood-waters from collapsing dam. The goal of seismologists is to understand the earthquake and other seismic activity on Earth. This information, when shared with people in earthquake prone areas, can help decrease the number of deaths and injuries that may occur. One of the most destructive effects of earthquake is tsunami. Tsunami, giant ocean waves, from after an earthquake has occurred on the ocean floor. If the tsunami crashes into land, it may cause destruction. The difficulty with protecting people from tsunami is that they may come without warning and at an extremely high speed. Once undersea earthquakes occur, the ocean floor rises and sinks. This is when tsunami may begin to form. Along with this shifting of the ocean floor, there is also a large masses of seawater that may drop or rise. To adjust the sudden change in sea level, the mass of water moves upward and downward. As it is moving, a series of reactions come long. Low waves begin to move from the point of the epicenter outward. These waves will increase in height as they come closer to the shore. Underwater landslides caused by earthquakes may also form tsunamis. On land, the focus of an earthquake's destruction is usually buildings and property. Most of the buildings today are built using strict building codes. These codes require that the building can withstand the swaying motion of the ground during an earthquake. However, there buildings, like skyscrapers, may sway so violently that they may tip over and cause damage to lower structures nearby. One factor that affects the intensity of an earthquake is the local geology. The type of land that beneath the buildings can determine the way the buildings respond to an earthquake. Building that are constructed on loose soil and rock. Likely soil and rock vibrate as if they were jelly. When buildings are constructed on this type of land, they tend to have an exaggerated motion and to sway violently.
