【精练】3. Toxicologist: A survey of oil-refinery workers whowork with MBTE, an ingredient currently usedin some smog-reducing gasolines, found analarming incidence of complaints aboutheadaches, fatigue, and shortness of breath.Since gasoline containing MBTE will soon bewidely used, we can expect an increasedincidence of headaches, fatigue, and shortnessof breath.Each of the following, if true, strengthens thetoxicologist’s argument EXCEPT:
没有看到except，还在纠结为什么会有好几个加强项，我真是活腻了……
逻辑链:调查表明，gasoline含有的MBTE含有令人BLABLABLA的物质，在这里工作的工人会BLABLABLA
因此，是MBTE罪魁祸首
问削弱或无关~~ ~~~
(A) Most oil-refinery workers who do not work withMBTE do not have serious health problemsinvolving headaches, fatigue, and shortnessof breath.——support(B) Headaches, fatigue, and shortness of breath areamong the symptoms of several medicalconditions that are potentially serious threatsto public health.——bingo！因为这个是一个常见的病，不一定是MBTE搞的(C) Since the time when gasoline containingMBTE was first introduced in a fewmetropolitan areas, those areas reported anincrease in the number of complaints aboutheadaches, fatigue, and shortness of breath.——support(D) Regions in which only gasoline containingMBTE is used have a much greater incidenceof headaches, fatigue, and shortness of breaththan do similar regions in which only MBTEfreegasoline is used.——support(E) The oil-refinery workers surveyed werecarefully selected to be representative of thebroader population in their medical historiesprior to exposure to MBTE, as well as inother relevant respects.——support

To prevent harbor porpoises from getting tangled in its nets and suffocating, a fishing company installed acoustic alarms on all its boats that fish in waters off Massachusetts. The sound emitted temporarily disorients the porpoises and frightens them away. Since the installation of the alarms, the average number of porpoises caught in the company's nets has dropped from eight to one per month. The alarms, therefore, are saving the lives of harbor porpoises in those waters.Which of the following is an assumption on which the argument depends?
逻辑链：为了保护HP,一个fishing公司在船上安装了警报器来把鱼吓走
这个措施让被捕到的鱼下降了
因此可以保护鱼
问assumption：为了保护HP，其他公司会不会装呢，如果其他没有，继续捕鱼，目的保护HP就不会达到了
(A) The use of acoustic alarms increases the number of commercial fish caught by the fishing company's boats.——irrelevant(B) When disoriented, harbor porpoises are not significantly more likely to be killed by other boats.——bingo！安装警报器会让鱼disorient，如果鱼这样会被其他船抓走，目的就达不到(C) Environmentalists advocate the use of acoustic alarms as a means of protecting the harbor porpoise population.——irrelevant(D) The alarms were installed at the time of year when harbor porpoises are most plentiful in the Massachusetts waters.——irrelevant(E) The cost of installing acoustic alarms on fishing boats is less than the cost of repairing nets damaged by harbor porpoises.——irrelevant，跟利益无关啊啊啊30. 1:05
An advertising agency must leave its office building. To save overhead costs, it is considering setting up a "virtual office" instead of moving to an adjacent office building. Employees will do their work on computers, as they do now, but will do so at home, sharing their work with colleagues by communicating text and designs to colleagues' computers through telephone lines, receiving typed comments, and then revising the work until it is satisfactory.Which of the following, if true, indicates a disadvantage of the virtual office plan?
逻辑链：为了节省成本，这个公司让员工回家工作，这样可以减少成本，而且通过邮件什么的可以进行交流
问缺点：会不会这个公司要经常开会，或者需要group工作呢(A) The agency can move its computers and associated equipment into employees' homes without purchasing any new equipment or requiring employees to purchase such equipment.——support(B) To reach the current office building and return home, employees spend an average of one and a half hours per day commuting, usually in heavy traffic.——support(C) The employees of the advertising agency are accustomed to autonomy in monitoring their own progress and productivity.——support(D) Employees would be able to adapt quickly to using computers in a virtual office setting, since employees' current use of computers to produce designs requires a high level of skill.——support(E) Expressions and gestures in face-to-face exchanges are an important aid to employees in gauging the viability of new ideas they have proposed.——bingo！面谈很重要31. 50sThe symptoms that United States President Zachary Taylor began showing five days before his death are consistent with arsenic poisoning. Recent examination of Taylor's bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor's contemporaries. These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal dose of the poison.Which of the following is most strongly supported by the statements given?
逻辑链：假设T是因为A毒死的
最近报告发现T骨头里的A含量比一般服用致死A剂量死去的人少很多
问结论：也就是Z不一定是因为A死的(A) The symptoms that Taylor began showing five days before his death are consistent with poisoning other than arsenic poisoning.——new information(B) Taylor's death was not the result of any kind of poisoning.——no sense(C) The symptoms that Taylor began showing five days before his death were not caused by a lethal dose of arsenic.——bingo！(D) The symptoms that Taylor began showing five days before his death grew more severe each day.——no sense(E) It is unusual for a person who has ingested a lethal dose of arsenic to survive for more than a day.——no sense |
