Water problem in the future will become more intense and more complex. Our increasing population will tremendously increase urban wasters, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for processing wasters. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volume of liquid wasters, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever-increasing quantities of agricultural chemicals. From this, it is apparent that serious steps must be taken immediately to develop corrective measures for the pollution problem.
There are two ways by which this pollution problem can be settled. The first relates to the treatment of wastes to decrease their pollution danger. This involves the processing of solid wasters
prior to
disposal and the treatment of liquid wasters to permit the reuse of the water or minimize pollution upon final disposal.
A second approach is to develop an economic use for all or a part of the wastes. Farm manure(肥料)is spread in fields as a nutrient or organic supplement. Wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Wastes from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are exploring potential economic uses for their waste products. [br] The phrase "prior to" in Paragraph 2 probably means______.
选项
A、during
B、after
C、before
D、beyond
答案
C
解析
语义词义题。按照常理推断,处理污水应该先过滤掉固体物质,然后再对剩下的液体进行处理,所以prior to一定是“在……之前”的意思。另外,在文章第二段的末尾有minimize pollution upon final disposal,与前面的disposal相对应,应该可以分析出,这个disposal是final的,所以prior to是“在……之前”的意思。故答案为C。
