章節(jié)摘錄

　　Correct Answer：C　　Argument Evaluation　　Reasoning:　　Conclusion:　　相比以往，更多人對(duì)長(zhǎng)時(shí)的政治信息感興趣?！　remise:　　一個(gè)半小時(shí)長(zhǎng)的競(jìng)選廣告的觀看人數(shù)有大幅提高。　　Solution:　　思考方向：　　并沒有更多人對(duì)長(zhǎng)時(shí)的政治信息那么感興趣?！　∷蛳魅酰骸　“胄r(shí)的競(jìng)選廣告是插播在很受歡迎的電視劇里，人們不得不看。　　A項(xiàng)：制作半小時(shí)長(zhǎng)競(jìng)選廣告的候選人在投票中并沒有贏得競(jìng)選；競(jìng)選最終結(jié)果與題目無關(guān)。　　B項(xiàng)：半小時(shí)長(zhǎng)的競(jìng)選廣告在播出之前已經(jīng)被廣泛推廣了；與人們對(duì)政治信息是否感興趣無關(guān)?！　項(xiàng)：為了更好接觸不同選民，多數(shù)競(jìng)選短片廣告插播在多種節(jié)目中；與題目無關(guān)?！　項(xiàng)：整體來說，含有時(shí)政辯論的常規(guī)時(shí)長(zhǎng)的電視節(jié)目是否受歡迎，主要倚賴電視節(jié)目里辯論仲裁人的個(gè)人魅力；與題目無關(guān)?！　?2. Two computer companies， Garnet and Renc09 each pay Salcor to provide health insurance for their employees. Because early treatment of high cholesterol can prevent strokes that would otherwise occur several years later， Salcor encourages Garnet employees to have their cholesterol levels tested and to obtain early treatment for high cholesterol. Renco employees generally remain with Renco only for a few years， however. Therefore， Salcor lacks any financial incentive to provide similar encouragement to Renco employees: Which of the following， if true， most seriously weakens the argument?　　A. Early treatment of high cholesterol does not eliminate the possibility of a stroke later in life:　　B. People often obtain early treatment for high cholesterol on their own*　　C. Garnet hires a significant number of former employees of Renco.　　D. Renco and Garnet have approximately the same number of employees.　　E. Renco employees are not， on average9 significantly younger than Garnet employees.　　Correct Answer：C　　Argument Evaluation　　Reasoning:　　Conclusion:　　Salcor公司缺乏財(cái)務(wù)獎(jiǎng)勵(lì)來為Renco員工提供類似的鼓勵(lì)方案?！　remise:　　Renco侖司的職員在Renco工作的時(shí)間不長(zhǎng)?！　olution：　　思考方向：　　Salcor公司愿意為Renco提供鼓勵(lì)方案，從中獲利?！　∫蚬怪茫骸　arnet公司中很大的一部分員工是Renco公司跳巢過來，從而Salcor公司可以賺兩次錢。　　A項(xiàng)：對(duì)膽固醇高進(jìn)行早期治療并不能在以后完全避免中風(fēng)的可能；與題目無關(guān)。　　B項(xiàng)：人們經(jīng)常自主接受降膽固醇的治療；支持了結(jié)論，并不是削弱?！　項(xiàng)：Renco和Garnet公司擁有近乎同等數(shù)量的員工；與題目無關(guān)。　　E項(xiàng)：Renco員工的平均年齡并不比Garnet員工年輕許多；與題目無關(guān)?！　?3. Though sucking zinc lozenges has been promoted as a treatment for the common cold， research has revealed no consistent effect. Recently， however， a zinc gel applied nasally has been shown to greatly reduce the duration of colds. Since the gel contains zinc in the same form and concentration as the lozenges， the greater effectiveness af the gel must be due to the fact that cold viruses tend to concentrate in'the nose， not the mouth. Which of the following， if true， most seriously weakens the argument?　　A. Experimental subjects who used the zinc gel not only had colds of shorter duration but also had less severe symptoms than did those who used a gel that did not contain zinc.　　B. The mechanism， by which zinc affects the viruses that cause the common cold has not been conclusively established.　　C. To make them palatable， zinc lozenges generally contain other ingredients， such as citric acid， that can interfere with the chemical activity of zinc.　　D. No zinc-based cold remedy can have any effect unless it is ta.ken or applied within 48 hours of the initial onset of cold symptoms.　　E. Drug-company researchers experimenting with a nasal spray based on zinc have found that it has much the same effect on coldsi.as the gel does.　　……
