Antarctica differs fundamentally from the Arctic regions. The Arctic is an ocean,(55)with drifting packed ice and surrounded by the land masses of Europe, Asia, and North America. The Antarctic is a continent nearly as(56)as Europe and Au stralia combined, centered roughly(57)the South Pole and(58)by the most unobstructed water areas of the world—the Atlantic, Pacific, and Indian Oceans.
The continental ice(59)is more than two miles high at its center; thus, the air over the Antarctic is far more refrigerated than it is over the Arctic regions. This(60)air cascades off the land with such(61)that it makes the nearby seas the stormiest in the world and renders(62)those regions whose counterparts at the opposite end of the(63)are inhabited. Thus, more than a million persons live within 2,000 miles of the North Pole in an area that(64)most of Alaska, Siberia, and Scandenavia—a region(65)in forest and mining industries. Except for a handful of weather stations, within the same distance of the South Pole there is not a single tree, industry, or settlement.
A.valleys
B.villages
C.paths
D.ranges

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.
