Japan is getting tough about recycling—and not inthe paper and plastic kind of way. Recently, thecountry requires that all electronic goods—TVs,VCRs, stereos, and more—be recycled. But recyclingwill not beleft to consumers, instead, the devices willbe sent to the original manufacturer for properdisposal.
The new law poses a few challenges to manufacturers who are now rushing to set up collectionnetworks and perfecting techniques to disassemble and recycle older products.With an eyetoward the future, they are also integrating easily recycled materials into new products.Plastics, a major component of most electronicproducts,pose a particular obstacle becausetheir quality becomes worse and worse 如何检查癫痫with age,losing strengthand flexibility even ifreprocessed.NEC Corp. overcomes this problem by creating a plastics sandwich, in which thefilling is 100 percent recycled plastic and the outer layers a mixture of 14 percent recycledmaterial.The resulting plastic has sufficient strength and toughness for use as a case fordesktop PCs. The company, in cooperation with plastic maker Sumitomo Dow, has alsodeveloped a new plastic, which engineers claim retains its mechanical properties throughrepeated recycling. NEC uses the plastic, which is also flame-retardant (阻燃的) in batterycases for notebook PCs.
Meanwhile, Matsushita Electric, maker of the Panasonic brand, is avoiding plastic in favor ofmagnesium (镁). Magnesium, says the company, is ideal for re cycling because it retains itsoriginal strength throughrepeated reprocessing. Matsushita西安癫痫病医院 has developed moldingtechniques to form magnesium into the case for a 21-inch TV. Unfortunately, the magnesiumcase and energy-saving features make the TV about twice as expensive as an ordinarymodel.The company hopes, however, that increased use of magnesium will eventually bringprices down.

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plastics sandwich 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plastics sandwich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(ideal for recycling),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。
