小編：環球教育整理 14588. The author is primarily concerned with
(A) showing that a certain interpretation is better supported by the evidence than is an alternative explanation
(B) developing an alternative interpretation by using sources of evidence that formerly had been unavailable
(C) questioning the accuracy of the evidence that most scholars have used to counter the author‘s own interpretation
(D) reviewing the evidence that formerly had been thought to obscure a valid interpretation
(E) presenting evidence in support of a controversial version of an earlier interpretation.
選 A
A 作者沒有否認 “ 農民不滿 ” 這個事實，而是對 F 提出的解釋提出了質疑，他先是用證據(句 2)否定了作者的證據(F 認為沒有新地了，實際上一直有)，然后提出了自己的解釋，是新的國際貿易格局中，蕭條波及了仍然有地的國家，導致產品價格一直下跌，農民才不滿。
關于蕭條再說幾句，粗糙地理解，蕭條就是有糧食賣不出去。對于國內農業 frontier 已經關閉的國家，也就是原有的土地上產出的糧食的價格受影響;對于仍然不斷開墾新地的國家(比如十九世紀晚期美國)，形勢是糧食本來就賣不出去，還增加供給(墾種新地，增產)，那可以想象價格就會一直走低，越跌越低，農民當然不開心。
9. According to the author, changes in the conditions of international trade resulted in an
(A) underestimation of the amount of new land that was being famed in the United States
(B) underutilization of relatively small but rich plots of land
(C) overexpansion of the world transportation network for shipping agricultural products
(D) extension of agrarian depressions beyond national boundaries
(E) emphasis on the importance of market forces in determining the prices of agricultural products
選 D
見句 5，“Consequently, agrarian depressions no longer were local or national in scope, and they struck several nations whose internal frontiers had not vanished or were not about to vanish.”
本句的 nations 當然包括美國，因為句 2 明確告訴我們，美國整個十九世紀及以后一直有 new lands 。
10. The author implies that, after certain territories and countries had been joined into an interdependent market system in the nineteenth century, agrarian depressions within that system
(A) spread to several nations, excluding those in which the internal frontier remained open
(B) manifested themselves in several nations, including those in which new land remained available for farming
(C) slowed down the pace of new technological developments in international communications and transportation
(D) affected the local and national prices of the nonagricultural products of several nations
(E) encouraged several nations to sell more of their agricultural products on foreign markets
選 B
見句 4、5、6 。
11. The author‘s argument implies that, compared to the yearly price changes that actually occurred on foreign agricultural markets during the 1880‘s, American farmers would have most preferred yearly price changes that were
(A) much smaller and in the same direction
(B) much smaller but in the opposite direction
(C) slightly smaller and in the same direction
(D) similar in size but in the opposite direction
(E) slightly greater and in the same direction
選 D
讓我們推測，1880 年代的美國農民，希望價格怎么變，用腳想都知道，他們希望價格大漲，他們好賺錢。
changes (價格)波動，文中我們知道，美國農民一直不滿，價格一直在跌，所以只能從 opposite direction 里選，淘汰 ACE，B 是“漲一點(比跌幅小得多)”，D 是“跟跌幅程度差不多的漲幅”。當然選 D 。好，穿襪子吧。
