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？

麻烦金老师回答，这题because 后面说明原因，原因还比较长，一句完整的话比较好，所以我首先考虑 A C D 然后在对比差异点上 关于到底是 especially 还是 specially ，还有削弱能力这个表达上实在选不出ACD 哪个更好 不是特别清晰

麻烦金老师回答，这题我读到的大概语意是M这类人居住在什么地方，后面的划线部分应该是紧接着修饰的，然后就没有下手点了，想听听老师的思路。

麻烦金老师帮我辨析一下BC 我能大概GET这题是在考比较考点，就是少数名族毕业生比其它类型的毕业生的四倍，我比较迷惑的点是C答案里面的这个as as ，这个不是同级比较么？顺着读，少数名族毕业生接近四倍和其它毕业生一样，感觉不通顺，相反我觉得B答案少数名族毕业生比其它类型的多四倍，读起来顺一点。我对比较级的这几个词理解的不是很透彻，麻烦老师帮忙辨析一下。

数学老师您好，这道是前两天更新的jj题目，因为我没有学过国内的高中数学，所以我不太能够理解答案里面所说的：K>0,可以判断出抛物线的极植点在x的上方？我想如果a（x-b)^2+k一直小于0，那这个抛物线就不会和x轴有交点

老师 我在想这道题是不是可以选A，我想的根据条件一，先假设中间大小的角和x相等，所以得出：3x+10+x+x=180，可以算出x和中间大小的角相等的情况下等于34，然而34应该是x最大的可能性，所以x一定小于34，锁体条件一单独成立。老师我不知道我的解题思路对不对，求指教

May老师，这道鸡精题目我算出来是A，确定答案对吗？

这题完全不懂 麻烦数学老师解答一下 谢谢

请数学老师讲解 一下图片题 另外我之前问的一道题 您没有解答清楚b选项 A certain list consists of 3 different numbers. Does the median of the 3 numbers equal the average (arithmetic mean) of the 3 numbers? (1)The range of the 3 numbers is equal to twice the difference between the greatest number and the median. (2)The sum of the 3 numbers is equal to 3 times one of the numbers.

麻烦金老师帮我解答一下这道语法题，首先我特别迷惑的点是关于这个which的指代，麻烦老师帮我辨析一下，之前老师说which不能指代整句话，要在前句有与之对应的名词，如果出现多个名词which的出现就会犯指代不清楚的错误，就是说前句只有一个名词不管是单复数都可以用which准确指代上是这个意思吗？刚开始做这题的时候一眼扫过去有results 和 company’s cost-cutting measures， profits 三个复数名词就排除掉了了ABC，因为我觉得which 在这里会犯指代不明的错误。事后看了正确答案，是因为of the company’s cost-cutting measures 只是results 的修饰语 ？那也还有profits 呢，从语意出发我觉得没毛病，但是这个which在这里有点指代不明。相反我觉得我错选的D答案前句的语意是“公司削减成本措施的结果在其利润中很明显”with。。（伴随）这这样一个结果，语意很通顺，也没有什么歧义，麻烦老师帮我辨析一下这几个点

麻烦金老师帮我解答一下这道语法题，老师我看到assumed 这个词就觉得后面应该接一个虚拟语气，我这样判断会不会太武断？我直接就排除掉ACD了 。还有就是纠结了一下这个代词的问题，这个IT指代到stategic ？, Morocco？关于这个their 犹豫了一下这个顺着读是摩洛哥对法国人感兴趣，但是看这个代词their 和 they 应该是法国人对摩洛哥感兴趣
