We can use plastics as a substitute_______wood.

C、 for

D、 instead of

everyday products such as beverage containers, toys, and furniture.The widespread use of plastics demands proper disposal of plastic waste.Plastics make up almost 13 percent of the urban solid waste stream, a dramaticincrease from 1960, when plastics were less than one percent of the wastestream. The largest category of plastics are found in containers and packaging(e.g. soft drink bottles, lids, shampoo bottles), but they are also found indurable (e.g. appliances, furniture) and nondurable goods (e.g. diapers, trashbags, utensils, and medical devices）. The recycling rate for different types ofplastics varies greatly, resulting in an overall plastic recycling rate of only8 percent, or 2.7 million tons in 2011.

Currently, the UShas the capacity to recycle plastics at a greater rate as a latest technologyhas come into being that helps in converting plastic waste disposal intoa good source of green fuel. A new process for turning plastics into fuel wasinvented. First, many different kinds of unwashed plastics are melted together.Then a special chemical is used to turn the fluid into a vapor（蒸汽）. Thisreduces the plastic to its most basic elements to make it have a high fuelvalue. It is tested that 86 percent of what goes in comes out as fuel. And 8percent of the recycled plastic is used to run the system. This technology willreduce the country’s dependence on foreign oil and theamount of plastic waste in its landfills（垃圾填埋场）．

Scientists sayplastic-to-oil technology is still new and developing. They say it is not yetknown if the process is environmentally friendly. And some question whetherturning plastics into oil can even be considered “recycling”.Carson Max is with the publication Resource Recycling, a magazine that reportson the plastic recycling industry. He says because there is a lot of plasticwaste and a great demand for oil, the recycling technology may create greatchanges in both industries. “So they’re getting value from something that would otherwise go to thelandfill, things that wouldn’t be accepted into a recycler.”

26. According to the article, the great increase in use ofplastic goods requires_______.

A. richer source of green fuel

27. The word “converting” inParagraph 2 most probably means “_______”．

A. coloring

C. consuming

D. transforming

28. What will the plastic-to-oil technology result in？

A. Less dependence on imported oil

B. Increase in plastic waste

C. Production of more plastic goods

D.Disappearance of landfills

29. What is Carson Max’s attitude towards the plastic-to-oiltechnology？

A. Positive

B. Negative

C. Critical

D. Indifferent

30. What is the passage mainly about？

A. The important function of plastics in everyday life

B. The new technology of plastic waste disposal

C. The development of plastics industry

D. The categories of plastics

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.

(23) 45 out of every 100 tones of wood fibre used to make paper in Australia comes from waste paper, the rest comes directly from virgin fibre from forests and plantations. By world standards this is a good (24) since the world-wide average is 33 percent waste paper. Governments have encouraged waste paper collection and (25) schemes and at the same time, the paper industry has responded by developing new recycling technologies that have (26) even greater utilization of used fibre. (27) , industry's use of recycled fibres is expected to increase at twice the rate of virgin fibre over the coming years.

Already, waste paper (28) 70% of paper used for packaging and advances in the technology (29) to remove ink from the paper have allowed a higher recycled (30) in newsprint and writing paper.
