CAB 儘管自然平衡的古老范式對於研究進化論和生態學的科學家來說根本毫無價值,但這個想法在美學上是令人滿意的,這一事實在很大程度上是其歷久彌新的原因。 ACA 儘管自然平衡的古老范式顯然是科學家研究進化論和生態學的基礎,但這個想法在美學上已經過時,這個事實在很大程度上是造成它被長期忽視的原因。 個人認為ACA較合適, 用邏輯來想,如果毫無價值怎麼會是范式呢?GRE不會考我們需要特定領域專業知識,我們不用去想生態學裡是否有自然平衡(我覺得肯定有).

Although the venerable paradigm of the balance of nature is (i)      scientists studying evolution and ecology, the idea is aesthetically (ii)      , a fact that is largely responsible for its (iii)      through the ages.

b^2 - 4ac大于0 不可以判断是否是为整数,考虑十字相乘的组合可能更为简洁明了

What is the least positive integer b such that the equation x2 +bx +18 =0 has two integer solutions for x?

提问:Fiera市的青少年犯罪率常年稳定,在curfew前一年激增12%,小概率事件持续的概率非常小,故第二年应当恢复原水平。所以Fiera的犯罪率在宵禁后下降10%究竟是回归定律在起作用,还是宵禁在起作用呢?

In an attempt to reduce the number of violent crimes committed by juveniles, the city of Fiera imposed a curfew requiring juveniles—everyone younger than eighteen—to be indoors between the hours of 11 P.M. and 6 A M. In the two years since the curfew was imposed, the number of violent crimes committed by juveniles in Fiera has fallen by almost ten percent. Clearly, therefore, the curfew has proven effective at reducing violent juvenile crime.

C选项的确提供了犯罪率回归平均值的可能,但注意这里只是一种可能性。 这里要weaken,我们还是要打破因果之间的逻辑链,即curfew并不一定是造成犯罪率下降的因素(例如,存在其他因素),那么D选项的这个事实,与犯罪率下降相关性高,也就是有其他因素在影响犯罪率。相比C与D,D的削弱更直接(most weaken)。

我这里理解的empire是大企业大集团,后面说地域分隔、出现独立政权我给理解成了地方政府可以给企业便利之类的以权谋私天高皇帝远那种意思55555,谁能知道这里empire就是政权啊

To understand what accounts for the durability of the Chinese empire, we must first (i)                   of deterministic explanations attributing it to an unusually convenient topographic setting. The empire’s terrain, divided into natural enclaves by mountain ranges and huge rivers, was as (i)                  the emergence of small independent polities as any other part of the world.

答案应该是 E

During the early years of the United States environmental movement in the 1960s and 1970s, alarmed activists, warning that nature was in danger of being irredeemably destroyed by human activity, demanded a variety of environmental protections, including the preservation of wilderness areas as national parks. But these environmentalists conceptual framework came under scrutiny shortly thereafter as cultural critics-especially those who were part of the theory revolution that transformed and preoccupied literary study into the end of the century-began to spread the postmodern wisdom that these parks musealized nature and that the wilderness they tried to preserve was not the primeval wild but a social construction. A consensus was growing that all areas of human life-from people's personal attitudes to the mediascapes they inhabited to the ideas they formed and the built worlds in which they dwelt-were socially constructed and these attitudes were quickly extended to nature, especially since ecologists and environmental historians had become so clear in demonstrating the determinative effects on nature of human beings, from ancient to modern times.

One important result of this change in thought was that a number of qualities that 1960s and 70s activist ecologists had felt nature self-evidently possessed seemed to be suddenly undercut and in a startling and provocatively contrarian manner. Most important, natures once apparent otherness seemed suddenly to be no more. In fact, it seemed to vanish in a number of different ways. Human beings had so encroached on nature, the apocalypticisms had shown, that nature was no longer independent of people.Supplementing this sense of radical contemporary change were environmental historians insights into how radically the earths ecosystems had been reshaped over the course of human history,from the emergence of mankind to the invention of agriculture to the rise of modern society. Ideas of a timeless or pure nature were thus discredited. Finally, on the level of intellectual history. nature's “otherness” was undermined in an equally decisive manner when cultural theorists began to argue that this supposed attribute was not only a socially constructed ideology, but an ideology of surprisingly recent vintage. The “otherness” of nature was an ideology that had been put in place during the romantic period of the nineteenth century-and put in place so decisively that it seemed to be the nature of nature.
