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？

请问郭老师 这是这次的寂静 请帮我分析一下下 如果问的是主旨 这主旨是啥？

请数学老师讲解思路 答案为1/30 谢谢老师

Although fruit can no longer grow once it is picked, it continues for some time to respire, taking in oxygen and giving off carbon dioxide, similar to the way human beings breathe. A similar to the way human beings breathe. B similarly to human beings who are breathing. C just like the breathing of human beings. D as human beings when breathing E just as human beings do when they breathe 老师，我在网上看到如下的答疑，similar to /like 只能就近修饰前面的n，所以ABC错误，这句话我不太理解，是说similar to和like在这里是修饰respire的吗？ 此外，还有个地方不理解，（like后面是不是应该+句子，similar to 后面+n ）才能表示比较呢？

请英吉老师回答~谢谢! 请老师看第五题，我当时看到C时是很想选C的，但是看完E后觉得E更直接，E说一些找不到停车位的车会在城里晃来晃去当等待游客时。我觉得原文建造停车场就能减少这个情况，挺像阐述逻辑链条的对立面的，请问我应该要怎样的的思路才能排除E呢？！谢谢~

请数学老师解答 勾股定理我已经忘的差不多了 这题怎么判断

请郭老师解答 另外b为什么是错的

请王文静老师回答，谢谢！这题我是这样下手的，AC分一组，强调advocate这个动作; BDE分一组重点倾向去修饰reformers这些人，所以我哦才留了BD. 请问老师这样想对吗？你在直播课里说advocate后面跟名词，我觉得这个算是比较细的语法点，请问advocate后加名词这个语法点是不会错的么？谢谢~

请王文静老师回答～谢谢！ 这题我不知道从何下手，感觉题目是说把用油的车换成用天然气的。所以，觉得前面应该要有“用油”这个表达和未划线部分的run on clearner-burning natural gas对应，所以我觉得BE比较对应。但答案是A..麻烦老师解答一下下手点！

思路： 能排除ACD，留下BE。 我一开始选了B因为觉得语义最通顺：本地猫起源于非洲野猫 4000年之前，which一个前所未有的短时间给本地猫进化以及 （4000年）是足够的为身体变化。 E 后面用的是一个同位语 divergence 指代主干的事情 这点我能接受 这个one 指的是谁啊？ 我一开始以为指的是时间 然后看Ron说 指代的是divergence 我就不能理解了。 网上搜到的解释给的答案是E。求老师讲解BE。 谢谢

19年OG这题貌似还没录入你们系统。 想问老师排除了ABC,当时在DE之间徘徊。。。后来选错了，但是D怎么不如E呢?
