tly, the country requires that all electronic goods—TVs, VCRs, stereos, and more—be recycled. But recycling will not beleft to consumers, instead, the devices will be sent to the original manufacturer for proper disposal.

The new law poses a few challenges to manufacturers who are now rushing to set up collection networks and perfecting techniques to disassemble and recycle older products.With an eye toward the future, they are also integrating easily recycled materials into new products. Plastics, a major component of most electronicproducts,pose a particular obstacle because their quality becomes worse and worse with age,losing strengthand flexibility even if reprocessed.NEC Corp. overcomes this problem by creating a plastics sandwich, in which the filling is 100 percent recycled plastic and the outer layers a mixture of 14 percent recycled material.The resulting plastic has sufficient strength and toughness for use as a case for desktop PCs. The company, in cooperation with plastic maker Sumitomo Dow, has also developed a new plastic, which engineers claim retains its mechanical properties through repeated recycling. NEC uses the plastic, which is also flame-retardant (阻燃的) in battery cases for notebook PCs.

Meanwhile, Matsushita Electric, maker of the Panasonic brand, is avoiding plastic in favor of magnesium (镁). Magnesium, says the company, is ideal for re cycling because it retains its original strength throughrepeated reprocessing. Matsushita has developed molding techniques to form. magnesium into the case for a 21-inch TV. Unfortunately, the magnesium case and energy-saving features make the TV about twice as expensive as an ordinary model.The company hopes, however, that increased use of magnesium will eventually bring prices down.

Choose correct answers to the question:

According to the present regulations of Japan, the recycling of paper and plastic will be the responsibility of______.

A.the government

B.a kind of plastics with different integration in each layer

C.a kind of plastics with maximum strength and flexibility

D.a kind of plastics made of 100% recycled materials

In the passage, it is implied but NOT stated that_____.A.disposing the plastics is one of NEC Corp’s businesses

B.magnesium is an ideal material for the case of TV

C.21-inch TV with magnesium case isn’t very popular so far

D.magnesium must be better than the plastics

nough to light lampBulbs—oreven to mn a small electric motoris almost unbelievable，but several kinds of fish are able todo this．Even more strangely。this curious power hasBeen acquired inDifferent waysBy fishBe。longing to veryDifferent families． Perhaps theBest known are the electric rays，or torpedoes(电鱼)，of which several kindslive in warm seas,They posses on each side of the head，behind the eyes，a large organ consis—ting of a number of hexagonal shaped cells rather like a honeycomb．The cells are filled with ajeUy—like substance，and contain a series of flat electric plates．One side，the negative side，ofeach plate．is supplied with very fine nerves，connected with a main nerve coming from a specialpart of theBrain．Current passes from the upper，positive side of the organDownwards to thenegative，lower side．Generally it is necessary to touch the fish in two places，completing the cir-cuit，in order to receive a shock． The strength of this shockDepends on the size of the fish，but newlyBorn ones only about5 centimeters across canBe made to light theBulb of a pocket flashlight for a few moments， while a fully grown torpedo gives a shock capable of knocking a manDown，and，if suitablewires are connected，will operate a small electric motor for several minutes． Another famous example is the electriceel．This fish gives an even more poweIful shock．The system i8Different from that of the torped。in that the electric plates run longitudinally(纵向)and ale supplied with nerves from the spinal(脊骨)cord．Consequefitly，the current passesalong the fish from head to tail．The electric or gans of these fish are really altered muscles andlike all muscles are apt(1ikely)to tire，so they are not able to produce electricity for very long．The power of producing electricity may serve these flshBom forDefence and attack． （）It canBe seen from the passage that__________．
