Passage Three

The whole industrial process which makes many of the goods and machines we need

and use in our daily lives, is bound to create a number of waste products which

upset the environmental balance or the ecological(生态的)balance as it is known. Many of these waste products can be prevented or disposed(处理) of sensibly, but clearly while more and more new goods are produced and made complex, there will

be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power

stations. Many people therefore see pollution as only part of a larger and more complex problem, that is,

the whole process of industrial production and consumption of goods. Others see the problem mainly in

connection with agriculture, where new methods are helping farmers grow more and more on their

land to feed our everincreasing population. However, the land itself is gradually

becoming worn out as it is being used, in some cases, too heavily, and artificial

fertilizers(人造肥料) cannot bring back the balance.

Whatever is underlying(潜在的)reasons, there is no doubt that much of the pollution caused could be controlled if only companies,

individuals and governments would make more efforts. In the home there is an obvious need to control litter(杂乱的废物)and waste. Food is wrapped up three or four times in packages that all have to be disposed of; drinks are

increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is

a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by

persuading many of us to buy things we don't want to buy. Pollution and waste continue to be a problem

everyone can help to solve by cutting out unnecessary buying, excess consumption and careless disposal of

the products we use in our daily lives.

44. The main cause of pollution is______.

A. the production of new industrial goods

B. increased amounts of unnatural substance

C. our ever-increasing population

D. the release of artificial substances into the environment
