Passage OneOn November 19, 1863, Abraham Lincoln went to Gettysburg in Pennsylvania to speak at the National Soldiers Cemetery. The Civil War was still going on. There was much criticism of President Lincoln at that time. He was not at all popular. He had been invited to speak at Gettysburg only out of courtesy. The principal speaker was to be Edward Everett, a famous statesman and speaker of the day. Everett was a handsome man and very popular everywhere.It is said that Lincoln prepared his speech on the train while going to Gettysburg. Late that night, alone in his hotel room and tired out, he again worked briefly on the speech. The next day Everett spoke first. He spoke for an hour and 57 minutes. His speech was perfect example of the rich oratory of the day. Then Lincoln rose. The crowd of 15,000 people at first paid little attention to him. He spoke for only nine minutes. At the end there was little applause. Lincoln turned to a friend and remarked, “I have failed again.” On the train back to Washington he commented sadly, “That speech was a flat failure, and the people are disappointed.”Some newspapers at first criticized the speech. But little by little, as people read the speech, they began to understand better. They began to appreciate its simplicity and its deep meaning. It was a speech which only Abraham Lincoln could have made.Today, every American school child learns Lincoln’s Gettysburg Address by heart. Now everyone thinks of it as one of the greatest orations ever given in American history.1. In 1863, Abraham Lincoln was _______A. very critical B. unpopularC. very popular D. very courteous2.

Since it affects human lives, it is a health problem. Since it affects property and health, it is an economic problem. Since it affects living organisms, it is a problem in conservation of natural resources. Since it affects the senses, it is an aesthetic problem.Man, like other organisms, has always polluted his environment with the by-products of his actions. As an organism, he removes wastes from his digestive and metabolic (新陈代谢) processes. As a social creature, he removes things from the environment and changes it as he seeks housing, clothing, food, and relaxation for his family unit. So long as population density is low in a particular area, the environment is able to accommodate these alterations. When population density gets too high, however, deterioration of the natural environment – air, water, and soil – begins.High population density is not the sole cause of the marked increase in pollution problems within the past two or three decades. Not only are populations growing in size, but they are also demanding a higher standard of living. Ever-increasing demands are made upon the earth’s natural resources for industrial purposes which, in turn, result in the formation of wastes.Why has this been allowed to happen? Many experts say that the basic reason is man’s failure to recognize that he is an integral part of nature. Traditionally man has viewed himself as being in a constant struggle with nature. Thus, to understand the present pollution problem and to take action that will halt and reverse the current trend, all of us need first to understand the interrelationships that exist between man and the rest of nature.6. Which of the following statements is TRUE according to the writer?A. Pollution is a health problem because it affects senses.B. Pollution is an economic problem because it affects living organisms.C. Pollution is entirely brought about by man’s digestive and metabolic processes.D. Besides man, other organisms also pollute the environment.7. It can be concluded from the passage that .A. if population density is well-controlled, pollution will be brought downB. man is so creative that he can eventually put an end to pollutionC. man always pollutes his surroundings on purposeD. the environment, once polluted, is irretrievable8. According to the passage, all the following statements are true EXCEPT .A. the recent grave pollution problems are caused exclusively by high population densityB. people are paying more attention to the improvement of living conditionsC. the more demands people make on natural resources, the more wastes are formedD. ever-increasing demands are also responsible for the increasing pollution problems9. According to the experts mentioned in the passage, .A. man is conquering nature B. nature manipulates manC. man is the opposite of nature D. man is a part of nature10. In order to cope with pollution, we need first to .A. solve the problem of the population boomB. slow down unrestricted economic growthC. know how serious environment pollution isD. understand the interrelationship between man and naturePassage ThreeDo you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labor through your work you may say that you’re “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as: “Get up, John! You’ll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.You can’t change your energy cycle, but you can learn to make you life fit it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning, but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle, but you’ll get up steam and work better at your low point.Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.11. If a person finds getting up early a problem, most probably__A. he is a lazy personB. he refuses to follow his own energy cycleC. he is not sure when his energy is lowD. he is at his peak in the afternoon or evening12. Which of the following may lead to family quarrels according to the passage?A. Unawareness of energy cycles.B. Familiar monologuesC. A change in a family member’s energy cycleD. Attempts to control the energy cycle of other family members13. If one wants to work more efficiently at his low point in the morning, he should_A. change his energy cycle B. overcome his lazinessC. get up earlier than usual D. go to bed earlier14. You are advised to rise with a yawn and stretch because it will___A. help to keep your energy for the day’s workB. help you to control your temper early in the dayC. enable you to concentrate on your routine workD. keep your energy cycle under control all day15. Which of the following statements is NOT TRUE?A. Getting off to work with a minimum effort helps save one’s energyB. Dr. Kletman explains why people reach their peaks at different hours of day.C. Habit helps a person adapt to his own energy cycleD. Children have energy cycles, too.Passage FourIt is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior.So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption (爆发) for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures.The speed of sound in water is roughly one mile a second --- slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean especially low-frequency ones can often travel thousands of miles.16. The passage is chiefly about .A. an effort to protect an endangered marine speciesB. the civilian use of a military detection systemC. the exposure of a U.S. Navy top-secret weaponD. a new way to look into the behavior of blue whales17. The underwater listening system was originally designed .A. to trace and locate enemy vesselsB. to monitor deep-sea volcanic eruptionsC. to study the movement of ocean currentsD. to replace the global radio communications network18. The deep-sea listening system makes use of .A. the sophisticated technology of focusing sounds under waterB. the capability of sound to travel at high speedC. the unique property of layers of ocean water in transmitting soundD. low-frequency sounds traveling across different layers of water19. It can be inferred from the passage that .A. new radio devices should be developed for tracking the endangered blue whalesB. blue whales are no longer endangered with the use of the new listening systemC. opinions differ as to whether civilian scientists should be allowed to use military technologyD. military technology has great potential in civilian use20. Which of the following is true about the U.S. Navy underwater listening network?A. It is now partly accessible to civilian scientists.B. It has been replaced by a more advanced system.C. It became useless to the military after the cold war.D. It is indispensable in protecting endangered species.
