标题: OG 12-51 谢谢大家 [打印本页] 作者: Sophin 时间: 2011-2-8 22:01 标题: OG 12-51 谢谢大家 51. One variety of partially biodegradable plastic beverage container is manufactured from small bits of plastic bound together by a degradable bonding agent such as cornstarch. Since only the bonding agent degrades, leaving the small bits of plastic, no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded.
Which of the following, if true, most strengthens the argument above?
(A) Both partially biodegradable and nonbiodegradable plastic beverage containers can be crushed completely flat by refuse compactors.
(B) The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to
compensate for the weakening effect of the bonding agents.
(C) Many consumers are ecology-minded and prefer to buy a product sold in the partially biodegradable plastic beverage containers
rather than in nonbiodegradable containers, even if the price is higher.
(D) The manufacturing process for the partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing process for nonbiodegradable plastic beverage containers.
(E) Technological problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container.
答案是B，请各位大牛们解释一下。。。谢谢 作者: crazyyeah 时间: 2011-2-9 01:15
两种饭盒: A饭盒是聚乙烯做的, B饭盒是聚乙烯加玉米纤维做的. 当它们扔掉土里的时候玉米纤维被降解了, 聚乙烯都留着. 所以B饭盒也会造成污染. B选项说, B饭盒的制造需要比A饭盒的聚乙烯更多, 所以加强了原文的结论, B饭盒的污染甚至比A的更大作者: Sophin 时间: 2011-2-9 11:17 标题: thanks 谢谢！解释得很具体。。。作者: 含草舵手 时间: 2012-6-22 13:08

下列哪一项加强以上观点？
(A) Both partially biodegradable and nonbiodegradable plastic beverage containers can be crushed completely flat by refuse compactors. 部分可生物分解和不可生物分解的塑料饮料容器都可以被垃圾压缩机所粉碎。
(B) The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bonding agents. 部分可生物降解饮料罐所用的塑料比不可降解的饮料罐用的塑料多，其目的是为了弥补粘合剂减弱的效果。
(C) Many consumers are ecology-minded and prefer to buy a product sold in the partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher. 许多顾客关系生态问题因此愿意购买部分可降解塑料容器而不愿购买不可降解容器，即使前者价格高。
(D) The manufacturing process for the partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing process for nonbiodegradable plastic beverage containers. 可降解塑料容器比不可降解容器的制作过程产生的垃圾废料要少
(E) Technological problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container. 当前循环利用的技术问题阻碍了塑料食品和饮料容器的再利用，无论其是否可降解。
