正确答案: D
125%
题目：某资本家投资100万元，每次投资所获得的利润为25万元，假定其资本有机构成为4：1，那么该资本家每次投资所实现的剩余价值率为（ ）
解析：本题考点：剩余价值率。 该题是考查政治经济学中的剩余价值率。剩余价值率m‘=m，利润与剩余价值在量上是一样的，都是25万元，资本有机构成为c：v=4：1，全部预付资本c+v为100万元，所以可变资本v为20万元，因此剩余价值率m’=25/20=125%，D为正确答案。

根据以下资料，回答下面的题目。The social sciences are flourishing.As of 2005,there were almost half a million professional social scientists from all fields in the world, working both inside and outside academia. According to the World Social Science Report 2010,the number of social-science students worldwide has swollen by about 11% every year since 2000.Yet this enormous resource in not contributing enough to today’s global challenges including climate change, security,sustainable development and health.(41)______Humanity has the necessary agro-technological tools to eradicate hunger , from genetically engineered crops to arificial fertilizers . Here , too, the problems are social: the organization and distribution of food, wealth and prosperity.(42)____This is a shame—the community should be grasping the opportunity to raise its influence in the real world. To paraphrase the great social scientist Joseph Schumpeter:there is no radical innovation without creative destruction .Today ,the social sciences are largely focused on disciplinary problems and internal scholarly debates,rather than on topics with external impact.Analyses reveal that the number of papers including the keywords “environmental changed” or “climate change” have increased rapidly since 2004,(43)____ When social scientists do tackle practical issues ,their scope is often local:Belgium is interested mainly in the effects of poverty on Belgium for example .And whether the community’s work contributes much to an overall accumulation of knowledge is doubtful. The problem is not necessarily the amount of available funding (44)____this is an adequate amount so long as it is aimed in the right direction. Social scientists who complain about a lack of funding should not expect more in today’s economic climate.The trick is to direct these funds better.The European Union Framework funding programs have long had a category specifically targeted at social scientists.This year,it was proposed that system be changed:Horizon 2020,a new program to be enacted in 2014,would not have such a category ,This has resulted in protests from social scientists.But the intention is not to neglect social science ; rather ,the complete opposite.(45)____That should createmore collaborative endeavors and help to develop projects aimed directly at solving global problems. 请在第____处填上正确选项。[A] It could be that we are evolving two communities of social scientists:one that is discipline-oriented and publishing in highly specialized journals,and one that is problem-oriented and publishing elsewhere,such as policy briefs.[B] However,the numbers are still small:in 2010,about 1,600 of the100,000 social-sciences papers published globally included one of theseKeywords.[C] the idea is to force social to integrate their work with other categories, including health and demographic change food security, marine research and the bio

根据以下资料，回答下面的题目。In the 2006 film version of The Devil Wears Prada, Miranda Priestly, played by Meryl Streep, scold her unattractive assistant for imagining that high fashion doesn’t affect her.Priestly explains how the deep blue color of the assistant’s sweater descended over the years from fashion shows to department stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn’t be more out of date or at odds with feverish world described in Overdressed, Elizabeth Cline’s three-year indictment of “fast fashion”.In the last decades or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely.Quckier turnrounds mean less wasted inventory, more frequent releases, and more profit.Those labels encourage style-conscious consumers to see clothes as disposal—— meant to last only a wash or two, although they don’t advertise that——and to renew their wardrobe every few weeks.By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking all industry long accustomed to a seasonal pace.The victims of this revolution, of course, are not limited to designers.For H&M to offer a 5.95 knit miniskirt in all its 2300-plus stores around the world, it must rely on low-wage, overseas labor, order in volumes that strain natural resources, and use massive amount of harmful chemicals.Overdressed is the fashion world’s answer to consumer activist bestsellers like Michael Pollan’s The Omnivore’s Dilemma.Mass-produced clothing, like fast food, fills a hunger and need, yet is non-durable, and wasteful,” Cline argues, Americans, she finds, buy roughly 20 billion garments a year——about 64 items per person——and no matter how much they give away, this excess leads to waste.Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named SKB, who, since 2008 has make all of her own clothes——and beautifully.But as Cline is the first to note, it took Beaumont decades to perfect her craft; her example, can’t be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment——including H&M, with its green Conscious Collection Line——Cline believes lasting-change can only be effected by the customer.She exhibits the idealism common to many advocates of sustainability, be it in food or in energy.Vanity is a constant; people will only start shopping more sustainably when they can’t afford to it.Priestly criticizes her assistant for her
