12、tate: 21 it, it would not be possible to pay the soldiers and policemen who protect us; 22 the workers in government offices who 23 our health, our food, our water, and all 24 things that we can not do for ourselves. By 25 of taxation, we pay for things that we need as 26 as we need somewhere to liv

13、e and something to eat. In most countries, a direct tax on persons, 27 is called income tax, exists. It is arranged in such a way that the poorest people pay 28 , and the percentage of tax grows greater as the taxpayers 29 grows. In England, for example, the tax on the 30 peo-ple goes up as high as

14、ninety-five percent! But countries with direct taxation nearly always have 31 taxation too. Many things imported into the country have to pay taxes or“duties“. 32 , it is the men and women who buy the imported things in the shops who really 33 pay the duties, in the 34 of higher prices. In some coun

15、tries, too, there is a tax 35 things sold in the shops. If the most necessary things are taxed, a lot of money is collected, but the poor people suffer 36. If unnecessary things like jewels and fur coats are taxed, 37 is obtained, but the tax is fairer, as the 38 pay it. Probably this last kind of i

20、. 40 Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in roboticsthe science of conferring various human capabilities on machines. And if scientists have yet to cr

21、eate the mechanical version of science fiction, they have begun to come close. As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly a

22、rms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can per

23、form some kinds of brain and bone surgery with submillimeter accuracyfar greater precision that highly skilled physicians can achieve with their hands alone. But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at

24、 least a few decisions for themselves goals that pose a real challenge. “While we know how to tell a robot to handle a specific error,“ says Dave Lavery, manager of a robotics program at NASA, “we cant yet give a robot enough common sense to reliably interact with a dynamic world.“ Indeed the quest

25、for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend tha

26、t forecast by decades if not centuries. What they found, in attempting to model thought, is that the human brains roughly one hundred billion nerve cells are much more talentedand human perception far more complicatedthan previously imagined. They have built robots that can recognize the error of a

27、machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of winding forest road or the single suspicious fac

28、e in a big crowd. The most advanced computer systems on Earth cant approach that kind of ability, and neuroscientists still dont know quite how we do it. 41 Human ingenuity was initially demonstrated in_. （ A） the use of machines to produce science fiction （ B） the wide use of machines in manufactur

29、ing industry （ C） the invention of tools for difficult and dangerous work （ D） the elites cunning tackling of dangerous and boring work 42 The word “gizmos“ (line 1, paragraph 2) most probably means_. （ A） programs （ B） experts （ C） devices （ D） creatures 43 According to the text, what is beyond man

30、s ability now is to design a robot that can （ A） fulfill delicate tasks like performing brain surgery （ B） interact with human beings verbally （ C） have a little common sense （ D） respond independently to a changing world 44 Besides reducing human labor, robots can also_. （ A） make a few decisions f

31、or themselves （ B） deal with some errors with human intervention （ C） improve factory environments （ D） cultivate human creativity 45 The author uses the example of a monkey to argue that robots are _ （ A） expected to copy human brain in internal structure （ B） able to perceive abnormalities immedia

32、tely （ C） far less able than human brain in focusing on relevant information （ D） best used in a controlled environment 45 The Supreme Courts decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled

33、 that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of “double effect“, a centuries-old moral principle holding that an action having two effectsa good one that is intended and a harmful one that is foreseenis permissible if the a

34、ctor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients pain, even though increasing dosages will eventually kill the patient. Nancy Dubler, director of Montefiore Medical Center, contends that the

35、 principle will shield doctors who “until now have very, very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death.“ George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescri

36、bes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. “Its like surgery,“ he says. “We dont call those deaths homicides because the doctors didnt intend to kill their patients, although they risked their death. If youre a

37、physician, you can risk your patients suicide as long as you dont intend their suicide. “ On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying

38、. Just three weeks before the Courts ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the under-treatment of pain and the aggressive use of “ineffectual and forced medical pro

39、cedures that may prolong and even dishonor the period of dying“ as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based car

40、e, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. “Large numbers of physicians seem unconcerned with the pain their patients are needlessly an

41、d predictably suffering,“ to the extent that it constitutes “systematic patient abuse.“ He says medical licensing boards “must make it clear. that painful deaths are presumptively ones that are incompetently managed and should result in license suspension. “ 46 From the first three paragraphs, we le

42、arn that_. （ A） doctors used to increase drug dosages to control their patients pain （ B） it is still illegal for doctors to help the dying end their lives （ C） the Supreme Court strongly opposes physician-assisted suicide （ D） patients have no constitutional right to commit suicide 47 Which of the

43、following statements is true according to the text? （ A） Doctors will be held guilty if they risk their patients death. （ B） Modern medicine has assisted terminally ill patients in painless recovery. （ C） The Court ruled that high-dosage pain-relieving medication should be prescribed. （ D） A doctors

44、 medication is no longer justified by his intentions. 48 According to the NASs report, one of the problems in end-of-life care is_. （ A） prolonged medical procedures （ B） inadequate treatment of pain （ C） systematic drug abuse （ D） insufficient hospital care 49 Which of the following best defines th

45、e word “aggressive“ (line 3, paragraph 7)? （ A） Bold （ B） Harmful （ C） Careless （ D） Desperate 50 George Annas would probably agree that doctors should be punished if they_. （ A） manage their patients incompetently （ B） give patients more medicine than needed （ C） reduce drug dosages for their patie

46、nts （ D） prolong the needless suffering of the patients 50 A weather map is an important tool for geographers. A succession of three of four maps presents a continuous picture of weather changes. Weather forecasts are able to determine the speed of air masses and fronts; to determine whether an indi

47、vidual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant functi

48、on of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time. All students of geography should be able to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a la

49、rge geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States weather Bureau issues information a-bout approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day “outlook“ which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an analysis of the upper air levels with often set the stage for the development of air
