题目内容
阅读下面短文，回答问题。 随着人类使用有机燃料的数量逐步增加，排入大气中的温室气体也越来越多。这些温室气体包括二氧化碳、甲烷、水蒸气、臭氧、氟利昂等。有关资料显示，最近35年间．大气中的二氧化碳含量增加了32.3%。目前，全世界仍在以每年220亿立方米的速度向大气排放二氧化碳。最近35年间，地球的平均气温达到15.3摄氏度，比工业化以前提高了0.7摄氏度。这一趋势不改变，人类的生存将面临严重威胁。 俄罗斯一些科学家在温室气体的利用方面进行了卓有成效的研究。他们认为，人类可以在燃烧产生的气体中分离出二氧化碳，把它用于生态上无害、经济上高效的生产工艺流程。比如用于食品、制冷工业，用来生产尿素、甲醇、碱、苛性钾等化工产品，可在冶金工业中充当金属的保护层，还可用于制造灭火剂。 俄罗斯科学家研究出一种应用干热电站的高效燃烧新工艺。这种新工艺的应用可以避免大量的废气尤其是温室气体排入大气，同时可从废气中得到浓度高达95%的工业用二氧化碳。提取这种二氧化碳所需的成本比常规方法大大减小。 另外，俄罗斯科学家还发明了一种将二氧化碳用于石油开采的新工艺。这种工艺是将石油开采中产生的伴生气体充分燃烧，可将燃烧产生的二氧化碳压入油层，增加油层的压力。 目前，这两种利用温室气体的工艺已经通过专家鉴定，并已开始在俄罗斯全国推广应用。 (佚名《温室气体利用与研究》) 第三段中“这种新工艺”的优点是： ①应用于热电站②避免废气产生③减少二氧化碳排入大气 ④提取高浓度工业用二氧化碳⑤降低二氧化碳提取的成本

Passage 4 Many United States companies have, unfortunately, made the search for legal protection from import competition into a major line of work. Since 1980 the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidence by foreign governments. Another 340 charge that foreign companies "dumped" their products in the United States at “less than fair value”. Even when no unfair practices are all alleged, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief. Contrary to the general impression, this quest for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop an intricate Web of marketing, production, and research relationships. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company. Internationalization increases the danger that foreign companies will use import relief laws against the very companies the laws were designed to protect. Suppose a United States-owned company establishes an overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports--and that the United States company received a subsidy from a foreign government to build its plant abroad--the United States company’s products will be uncompetitive in the United States, since they would be subject to duties. Perhaps the most brazen case occurred when the ITC investigated allegations that Canadian companies were injuring the United States salt industry by dumping rock salt, used to deice roads. The bizarre aspect of the complaint was that a foreign conglomerate with United States operations was crying for help against a United States company with foreign operations. The "United States" company claiming injury was a subsidary of a Dutch conglomerate, while the "Canadian" companies included a subsidary of a Chicago firm that was the second largest domestic producer of rock salt. The passage warns of which of the following dangers
