In the passage the author is primarily concerned with ________. likely be ______. D. executions and murders63. The author39。 B. the effects of execution and the effects of isolation D. argue for the value of the death penalty62. The passage attempts to establish a relationship between ______. B. initiate a vetos murder rate, which began when executions stopped, is no coincidence. It is convincing evidence that the death penalty does deter many murderers. If the bill reestablishing the death penalty is vetoed, innocent people will be murderedsome whose lives may have been saved if the death penalty were in effect. This is literally a life or death matter. The lives of thousands of innocent people must be protected.61. The principal purpose of this passage is to ________. With the possible exception of equal rights, perhaps the most controversial issue across theUnited States today is the death penalty. Many argue that it is an effective deterrent (威懾) to murder, while others maintain there is no convincing evidence that the death penalty reduces the number of murders.D. Biology and the Scientific AgeC. The Nature of Science and ScientistsB. On Distinguishing Fact from FictionA. Hypotheses and Theories D. necessarily precedes applied science, leading to the discovery of the cell58. A scientist interested in adding to our general knowledge about oxygen would probably call his approach _______.A. pure scienceB. environmental scienceC. applied scienceD. agricultural science59. Which of the following statements does the author imply?A. In science, it is not difficult to distinguish fact from fictionB. Practicalminded people can understand the meaning and objectives of pure science.C. Scientists engaged in the theoretical research should not be blamed for ignoring the practical side of their discoveries.D. Today few people have any nation of the meaning of science.60. The best title for the passage is B. necessarily results from applied science and the discovery of a cell D. an attempt to explain natural phenomena57. Pure science, leading to the construction of a microscope, ________. B. classified knowledge they know from experience that most knowledge is eventually applied.56. To define science we may simply call it ________. Sometimes practicalminded people miss the point of pure science in thinking only of its immediate application for economic rewards. Chemists responsible for many of the discoveries could hardly have anticipated that their findings would one day result in applications of such a practical nature as those directly related to life and death. The discovery of one bit of information opens the door to the discovery of another. Some discoveries seem so simple that one is amazed they were not made years ago。 he must solve them. Toward that end specialists in the field of biology and related fields of interest are directing much of their time and energy. Even in the true sciences distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses (假設) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited (使不相信). The exacts status of any explanation should be clearly labeled to avoid confusion. The word science is heard so often in modem times that almost everybody has some notion of its meaning. On the other hand, its definition is difficult for many people. The meaning of the term is confused, but everyone should understand its meaning and objectives. Just to make the explanation as simple as possible, suppose science is defined as classified knowledge (facts).Passage Five C. They should replace all the harmful substances. A.
