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？

作文，感觉这个有点难找，有些地方不知道驳了算不算抬杠，请英吉老师指点一下改善一下我的思路，谢谢！

作文，感觉这个找不到更多点能驳了，请英吉老师赐教！以及马上要考试了，请问作文一定要找四个以上才稳吗？

May老师，我这个题解出来是纯算数做出来，感觉有点麻烦，有没有比较简便的方法可以做这个题呢？ 谢谢老师

金栩竹老师，这道题为什么要选择to doing 呢？to do 与to doing有哪些区别呢？感觉没怎么见过to doing 的形式。

Tina老师，这个E的those of 没有问题吗？这个指代的是哪里呢？ B哪里有问题呢？C的错误是在of嘛？

Tina老师，这个come在这里是谁的谓语呀，前面efforts 的谓语不是aimed吗？这里也只有一个连词，连词后的account不也是谓语么。

【张慧雯】老师 不好意思，不好意思🤦‍♀️ 刚刚手抖打错字了。 就是这道题，我刚重新看了一会，文章思路大致有了谱，但是这个题要问什么，自己怎么定位到原文这里，不太懂了。其他题中，像这样的，让你找最不可能的，排除东西做的题，也都不太懂🤦‍♀️

请英吉老师看一下我这个作文的思路有无什么不足，打问号的是我不太确定的，谢谢！
