2017年英語四級閱讀理解能力提升訓(xùn)練題
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 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 (鎂). Magnesium, says the company, is ideal for re cycling because it retains itsoriginal strength throughrepeated reprocessing. Matsushita 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.

參考答案
1.[C] 推理判斷題。文章首段提到了電子產(chǎn)品的回收利用與紙張和塑料不同;本段最后一句中的but表明了以上不同點(diǎn)在于電子產(chǎn)品的回收不依靠消費(fèi)者，而依靠生產(chǎn)者。結(jié)合以上兩點(diǎn)，可以推斷紙張和塑料的回收利用主要靠消費(fèi)者，因此選項(xiàng)C為正確答案。
2.[B] 事實(shí)細(xì)節(jié)題。本題考査列舉處。第2段第3句列舉了塑料的特性，對照選項(xiàng)和該句，就能發(fā)現(xiàn)文中明確提到選項(xiàng)A、C、D,而選項(xiàng)B顯然與原文意思相反。
3.[B] 事實(shí)細(xì)節(jié)題。本題考査復(fù)合句的理解。第2段第4句是一個非限制性定語從句，是plastics sandwich 的定義，選項(xiàng)B是對該定語從句所述亊實(shí)的總結(jié)，因此選項(xiàng)B正確。選項(xiàng)A在文中沒有提及;選項(xiàng)C中的maximum是對原文sufficient的曲解;選項(xiàng)D中的100%這一數(shù)據(jù)不準(zhǔn)確，文中只提到plastics sandwich里層是100%的再生塑料。
4.[C] 推理判斷題。本題考査轉(zhuǎn)折處。最后一段倒數(shù)第2句中的Unfortunately一詞指出了用鎂作機(jī)殼的'電視機(jī)很貴，從而暗示它們并不受消費(fèi)者歡迎，所以選項(xiàng)C正確。選項(xiàng)A屬原文明確表達(dá)的意思。本段第2句只指出鎂是一種理想的再生材料(ideal for recycling),因此選項(xiàng)B不對;全文并未比較塑料和鎂哪個更好，因此選項(xiàng)D不對。
5.[A] 主旨大意題。文中作者只是客觀地描述亊實(shí)，吿知讀者日本的電子產(chǎn)品再循環(huán)使用的一些新變化和新技術(shù)，抓住這個主旨就能選出正確答案A。作者并未發(fā)表任何個人觀點(diǎn)，也未做出任何指示或預(yù)測。
