　　Cell Phones Increase Traffic, Pedestrian Fatalities(手机增加交通行人死亡)

2017年职称英语试题理工类复习模拟试题及答案

　　Cell phones are a danger on the road in more ways than one. Two new studies show that talking on the phone while traveling, whether you're driving or on foot, is increasing both pedestrian deaths and those of drivers and passengers, and recommend crackdowns on cell1 use by both pedestrians and drivers。

　　手机在路上有多种多样的危险。两个新的研究表明，不管开车还是步行时打手机，都会增加行人、司机和乘客死亡的危险，所以该研究建议严厉限制行人和司机使用手机。

　　The new studies, lead-authored by Rutgers University, Newark, Economics Professor Peter D. Loeb2, relate the impact of cell phones on accident fatalities to the number of cell phones in use, showing that the current increase in deaths resulting from cell phone use follows a period when cell phones actually helped to reduce pedestrian and traffic fatalities. However, this reduction in fatalities disappeared once the numbers of phones in use reached a "critical mass" 3 of 100 million, the study found.

　　这是一项第一作者为罗格斯大学纽瓦克分校的经济学教授Peter D. Loeb的新研究成果，它把手机的意外Ic命的影响和大量手机使用数量联系起表明目前由于手机所引起的死亡数目有所增加，而在此之间的一段时间里，手机事实上能够帮助降低行人和交通致命率。但研究发现，当手机使用人数达到1亿这个临界数量时，手机降低交通致命率的作用就消失了。

　　These studies looked at cell phone use and motor vehicle accidents from 1975 through 2002, and factored in4 a number of variables, including vehicle speed, alcohol consumption, seat belt use, and miles driven. The studies found the cell phone-fatality correlation to be true even when including factors such as speed, alcohol consumption, and seat belt use.

　　这些研究涉及到从1975年到2002年间的手机使用和机动车辆事故之间的关系，也涉及包括车速、酒精消耗、安全带的使用和行驶的里数等其他方面。这些研究表明甚至当考虑比如速度、酒精消耗和安全带的使用这些因素时，二者之间的关联也是真实存在的。

　　Loeb and his co-author determined that, at the current time, cell phone use has a "significant adverse effect on pedestrian safety" and that “cell phones and their usage above a critical threshold5 adds to motor vehicle fatalities." In the late 1980s and part of the 1990s, before the numbers of phones exploded, cell phone use actually had a "life-saving effect" in pedestrian and traffic accidents, Loeb notes. "Cell-phone users' were able to quickly call for medical assistance when involved in an accident. This quick medical response actually reduced the number of traffic deaths for a time," Loeb hypothesizes.

　　在目前，Loeb和他的合者决定手机的使用“在行人安全上有严重的反作用”并且“手机的使用数量已经超过了临界数量也增加了机动车辆的致命性。”在20世纪80年代末和90年代的一段时间，在手机使用数量达到大爆炸之前，手机的使用确实在交通事故中起到过“保护生命的作用”。“当发生交通意外时，手机使用者能够快速地打电话寻求医疗帮助，这种快速的医学求救反应确实能在一定时间内减少一定数量的事故死亡”，Loeb假设。

　　However, this was not the case when cells were first used in the mid-1980s, when they caused a "life-taking effect" among pedestrians, drivers and passengers in vehicles. In those early days, when there were fewer than a million phones, fatalities increased, says Loeb, because drivers and pedestrians probably were still adjusting to the novelty of using them, and there weren't enough cell phones in use to make a difference in summoning help following an accident, he explains.

　　但是，在20世纪80年代当手机开始被使用时并不是这样，在那时手机在行人、司机和乘客间造成了 “致命的效果。”在早些日子里，那时有不到一百万部手机，致命率增加了，Loeb说，因为司机和行人或许在那时还在适应怎样使用它们，还没有足够的手机能够在事故中呼叫帮助，他解释说。

　　The "life-saving effect" occurred as the volume of phones grew into the early 1990s, and increasing numbers of cells were used to call 911 following accidents, leading to a drop in fatalities, explains Loeb. But this life-saving effect was canceled out6 once the numbers of phones reached a "critical mass" of about 100 million and the "life-taking effect" - increased accidents and fatalities outweighed the benefits of quick access to 911 services, according to Loeb.

　　这“保护生命的效果”是在20世纪90年代当大数量的手机被使用的时候出现的，越来越多的手机在事故之后拨打“911” .求助，这就降低了致命率，Loeb解释说。但是一旦手机的使用量超过大约一亿的“临界数量”时，这种保护生命的效果就被抵消了，而且这种“致命的效果”——增加了事故和死亡——超过了能快速呼叫“911”服务的好处，根据Loeb所说。

　　Loeb and his co-authors used econometric models to analyze data from a number of government and private studies. He and his co-authors recommend that governments consider more aggressive policies to reduce cell phone use by both drivers and pedestrians, to reduce the number of fatalities.

　　Loeb和他的合著者们使用计量经济模式来分析从许多政府和私人研究中得来的数据。他和他的合著者们都推荐政府采取强制性措施来减少司机和行人的手机使用数量，来减少死亡事件的发生。

　　A Right after cell phones were invented.

　　B Before the number of cell phone users reached a critical mass

　　C When cell phone users totaled to a certain number.

　　D When the number of cell phones decreased to a certain number.

　　3. What is said about cell phone use in paragraph 4?

　　A The number of cell phones in use exploded in the late 1980s and part of the 1990s.

　　B The number of traffic deaths was reduced in the late 1980s and part of the 1990s due to cell phone use.

　　C Cell phone users are likely to be involved in traffic accidents.

　　D The use of cell phones has a life-saving effect for pedestrians and drivers.

　　4. What is said about cell phone use in the mid-1980s in paragraph 5?

　　A It had a life-taking effect because there weren't enough cell phones in use then.

　　B The increased use of cell phones then caused a "life-taking effect."

　　C Traffic fatalities increased then because the number of cell phones in use decreased.

　　D Traffic fatalities decreased then because the number of cell phones in use increased.

　　5. Which of the following statements DOES NOT answer the question "What caused the "life-saving effect" to occur in the early 1990s?"

　　A There were more cell phone users during that period.

　　B The number of cell phone users reached about 100 million.

　　C More cell phones were used to call 911 when accidents occurred.

　　D Cell phones enabled people to have quick access to 911 services.

　　答案与题解：

　　1. D 根据短文第一段的内容，Loeb 教授的最新研究发现，开车或行路时打手机使司机和行路人的死亡率上升，并建议采取严厉措施限制司机和行路人使用手机。B 是错误理解，因为只有行路人被提到。

　　2. B 短文第二段最后两个句子提供了答案：在手机使用者达到 1 亿的临界点之前，手机的使用的确减少了交通事故的死亡率。A、C 和 D 的表述内容都没有在文章中提到。

　　3. B A 是错误选择，因为该段的第四个句子 In the late 1980s and part of the 1990s, before the numbers of phones exploded, ...表明。手机数量在 80 年代末期和 90 年代早期还未激增。C 的表述内容没有在文章中提到。句子…cell phone use actually had a “life-saving effect”用的是过去式，说的是发生在 80 年代末期和 90 年代早期的事情，而 D 句用的是一般现在时，表示通常的状况，所以是错误的选择。

　　4. A第五段的大概意思是，80 年代中期，交通事故的死亡率增加，因为人们还在适应这一新事物，没有足够的手机让人们在发生交通事故时及时求救。该段没有讨论 80 年代中期手机数量的增减问题，所以 B、C 和 D 都是错误选择。

　　5. B第六段最后一个句子说，当手机使用者数量达到 100 万时，life-saving effect 就被抵消了，life-saving effect 超过了手机使用者能迅速呼叫 911 服务的优点。所以，B 不是问题的答案。其他选项都表述了该段的内容。

　　The Worker's Role in Management

　　Traditionally, it has been the worker's role to worker and management's role to mange. Managers have planned and directed the firm's operation with little thought consulting the labor force. Managers have rarely felt compelled to obtain the worker's opinions or to explain their decisions to their employees. At most, companies have provided "suggestion boxes" in which workers could place ideas for improving procedures. In recent years, however, many management specialists have been arguing that workers are more than sellers of labor-they have a vital stake in the company and many be able to make significant contributions to its management. Furthermore, major company decisions profoundly affect workers and their dependents. This is particularly true of plant closings, which may put thousands on the unemployment lines. Should workers, then, play a stronger role in management?

　　Workers should have a role in management. At the very least, the labor force should be informed of major policy decisions. (A common complaint among rank-and-file workers is the lack of information about company policies and actions.) Between 1980 and 1985 about five million workers were the victims of plant closings and permanent layoffs, often with no warning. At least 90 day's notice ought to be given in such instances so that workers have time to adjust. Management should consult workers before closing a plant, because the workers might be able to suggest ways of improving productivity and reducing costs and might be willing to make concessions that will keep the plant operating.

　　It should become a general practice to include workers in some managerial decision making. There ought to be representatives of the workers on the firm's board of directors or other major policymaking groups. If rank-and-file workers are given a voice in the planning and management of the work flow, they will help to make improvement, their morale will rise, and their productivity will increase. As a further incentive, they must be given a share in the company's profits. This can be done through employee stockownership plans, bonuses, or rewards for efficiency and productivity. Finally, when a plant can no longer operate at a profit, the workers should be given the opportunity to purchase the plant and run it themselves.

　　A. Right

　　B. Wrong

　　C. No mentioned

　　An Observation and Explanation

　　It is worth looking at one or two aspects of the way a mother behaves towards her baby. The usual fondling, cuddling and cleaning requite little comment, but the position in which she holds the baby against her body when resting is rather revealing. Careful studies have shown the fact that 80 per cent of mothers hold their infants in their left arms, holding them against the left side of their bodies. If asked to explain the significance of this preference most people reply that it is obviously the result of the predominance of right-handedness in the population. By holding the babies in their left arms, the mothers keep their dominant arm free for manipulations. But a detailed analysis shows that this is not the case. True, there is a slight difference between right-handed and left-handed females; but not enough to provide an adequate explanation. It emerges that 83 per cent of right-handed mothers hold the baby on the left side, but so do 78 per cent of left-handed mothers. In other words, only 22 per cent of the left-handed mothers have their dominant hands free for actions. Clearly there must be some other, less obvious explanation.

　　The only other clue comes from the fact that the heart is on the left side of the mother's body. Could it be that the sound of her heart-beat is the vital factor? And in what way? Thinking along these lines it was argued that perhaps during its existence inside the body of the mother the unborn baby gets used to the sound of the heart beat. If this is so, then the re-discovery of this familiar sound after birth might have a calming effect on the infant, especially as it has just been born into a strange and frighteningly new world. If this is so then the mother would, somehow, soon arrive at the discovery that her baby is more at peace if held on the left against her heart, than on the right.

　　1. We can learn a lot by observing the position in which a mother holds her baby against her body
