文章：According to many analysts, labor-management relations in the United States are undergoing a fundamental change: traditional adversarialism is giving way to a new cooperative relationship between the two sides and even to concessions from labor. These analysts say the twin shocks of nonunion competition in this country and low-cost, high-quality imports from abroad are forcing unions to look more favorably at a variety of management demands: the need for wage restraint and reduced benefits as well as the abolition of "rigid" work rules, seniority rights, and job classifications. Sophisticated proponents of these new developments cast their observations in a prolabor light. n return for their concessions, they point out, some unions have bargained for profit sharing, retraining rights, and job--security guarantees. Unions can also trade concessions for more say on the shop floor, where techniques such as quality circles and quality-of-work­ life programs promise workers greater control over their own jobs. Unions may even win a voice in investment and pricing strategy, plant location, and other major corporate policy decisions previously reserved to management. Opponents of these concessions from labor argue that such concessions do not save jobs, but either prolong the agony of dying plants or finance the plant relocations that employers had intended anyway. Companies make investment decisions to fit their strategic plans and their profit objectives, opponents point out, and labor costs are usually just a small factor in the equation. Moreover, unrestrained by either loyalty to their work force or political or legislative constraints on their mobility, the companies eventually cut and run, concessions or no concessions. Wage-related concessions have come under particular attack, since opponents believe that high union wages underlay much of the success of United States industry in this century. They point out that a long-standing principle, shared by both management and labor, has been that workers should earn wages that give them the income they need to buy what they make. Moreover, high wages have given workers the buying power to propel the economy forward. f proposals for pay cuts, two-tier wage systems, and subminimum wages for young workers continue to gain credence, opponents believe the U.S. social structure will move toward that of a less-developed nation: a small group of wealthy investors, a sizable but still minority bloc of elite professionals and highly skilled employees, and a huge mass of marginal workers and unskilled laborers. Further, they argue that if unions willingly engage in concession bargaining on the false grounds that labor costs are the source of a company's problems, unions will find themselves competing with Third World pay levels-a competition they cannot win. 想请问郭老师，这题opponents观点是在第三段，但是原文和选项要怎么对照呢...怎么从观点看出态度？

这道题感觉像是要找规律，但还是没有思路，想请教一下老师，谢谢

麻烦唐瑭老师解答一下～这道题在做的时候我其实问题有点没读懂，就读了最后一句，然后提取出来的关键点是在讲tax一直在征收but汽油的税收没有增加，只有CE选项提到的汽油，但是C在讲汽油进口是新东西，所以我选了E。想麻烦老师解释一下正确选项C，再告知一下这道题应该看哪句话。谢谢～

这道题答案选E但我选了D，难道这里的land不是动词然后intact不应该用副词吗？求解答谢谢！

麻烦唐瑭老师解答一下～这道题我做对了，但是没太懂，我定位了最后一句，感觉在讲maize和monarch butterfly之间的关系。没太读懂各选项，但只有C提到了这两个东西，所以选了C。麻烦老师讲解一下～

请王文静老师回答一下这个问题，谢谢！具体疑惑附在图二了

麻烦唐瑭老师解答一下～这道题看了题目后我没有回看题干，想问一下题目是不是在说利润增涨和涨价没有关系？我选了D，正确答案C，麻烦老师讲一下CD，谢谢～

这道题选E，我错选了D，请唐瑭老师讲解一下这种类型的题该怎么写？必须看完全文吗？怎么对比选项？希望老师把方法讲得详细一点，谢谢！

请王文静老师解答一下，谢谢1.不太会判断ACD（C是因为the magazines’…consumption to convince…money无法作主语？D是因为with不好所以排除？2. 感觉后半段“出版者说服R地中产去花钱是内政主要部分”和破折号之前部分的句意并列不了

老师我想问一下这道题，从6b=ab不是可以推出a=6吗，有点懵，求解答谢谢老师！

这道题答案选A，请问老师怎么用A推出来呀？我自己总感觉虽然能确定四个数的大小，但是比值大小不太确定
