1.[C]推理判断题。文章首段提到了电子产品的回收利用与纸张和塑料不同;本段最后一句中的but表明了以上不同点在于电子产品的回收不依靠消费者,而依靠生产者。结合以上两点,可以推断纸张和塑料的回收利用主要靠消费者,因此选项C为正确答案。
2.[B]事实细节題。本题考査列举处。第2段第3句列举了塑料的特性,对照选项和该句,就能发现文中明确提到选项A、C、D,而选项B显然与原文意思相反。
3.[B]事实细节题。本题考査复合句的理解。第2段第4句是一个非限制性定语从句,是plasticssandwich的定义,选项B是对该定语从句所述亊实的总结,因此选项B正确。选項A在文中没有提及;选项C中的maximum是对原文sufficient的曲解;选项D中的100%这一数据不准确,文中只提到plasticssandwich里层是100%的再生塑料。
4.[C]推理判断题。本题考査转折处。最后一段倒数第2句中的Unfortunately一词指出了用镁作机壳的电视机很贵,从而暗示它们并不受消费者欢迎,所以选项C正确。选项A属原文明确表达的意思。本段第2句只指出镁是一种理想的再生材料(idealforrecycling),因此选项B不对;全文并未比较塑料和镁哪个更好,因此选项D不对。
5.[A]主旨大意题。文中作者只是客观地描述亊实,吿知读者日本的电子产品再循环使用的一些新变化和新技术,抓住这个主旨就能选出正确答案A。作者并未发表任何个人观点,也未做出任何指示或預测。
