本题考查为“the main idea of the passage”,
全文思路为:提出integrated producers困难的原因,以及minimills避免economical problem的方法。这种对比关系一定要存在于选项之中。
纵观选项,只有
“Minimills and specialty-steel mills are more economically competitive than integrated producers because they use new technology and avoid the costs of the iron-smelting process”最为合适
22(A)
根据“features of minimills”及各选项定位原文
选项(A)—“whereas specialty-steel mills preserve flexibility in their operations”,故错误
选项(B)—“they sell their finished products locally”,故正确
选项(C)—“the minimills, …, have dispensed almost entirely with …the iron-smelting process, including the mining and preparation of the raw materials and the blast-furnace operation”,正确
选项(D)—“Both take advantage of new technology for refining and casting steel, such as continuous casting, as soon as it becomes available”,故正确
选项(E)—“The minimills reprocess scrap steel into a limited range of low-quality products,”
正确
23(C)
根据“Japanese integrated producers”定位原文
“One might conclude that the older labor-intensive machinery still operating in United States integrated plants is at fault for the poor performance of the United States industry, but this cannot explain why Japanese integrated producers, who produce a higher-quality product using less energy and labor, are also experiencing economic trouble.” Japanese integrated producers用于反驳红色字体,即
“labor-intensive machinery cannot be blamed for the economic condition of United States integrated steel producers”
24(E)
根据“the organization of the third paragraph”定位第三段
作者先提出假设性原因“excessive labor, energy, and capital costs, as well as manufacturing inflexibility”,接着详述,再Japanese例反,最后提出“an inherently inefficient process”,即
选项(E)概括最佳
“General statements are made and details given; then an explanation is proposed and rejected, and an alternative is offered”
25(E)
查找“specialty-steel mills”的特点
“the minimills, like specialty-steel mills, have dispensed almost entirely with the archaic energy and capital-intensive front end of integrated steelmaking: the iron-smelting process, including the mining and preparation of the raw materials and the blast-furnace operation”
选项(E)为直接转述
“do not operate blast furnaces; }/”
26(A)
作者自始至终并没有提到raw material不足的问题,只是说明处理方法的不同带来economic development的不同
“a paper-manufacturing company that experiences difficulty in obtaining enough timber and other raw materials to meet its orders”
27(E)
关键词“supporting evidence”,“explanation of the economic condition of integrated steel producers”
明确integrated steel producers面临的困难及产生困难的原因即可正确作答本题
只有选项(E)最为接近
“Those nations in which iron-smelting operations are carried out independently of steel production must heavily subsidize those operations in order to make them profitable”
