Question

The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.
小題1:What is most likely to be discussed in the paragraph that follows?

A．Ways to reduce the costs of building dams.

B．Steps to improving water use management.

C．Measures to deal with worldwide water shortages.

D．Approaches to handling the pressure on water supply.

小題2:From the first two paragraphs we learn that________.

A．much of the world's water is available for use

B．people in high rainfall countries feel lucky

C．the costs of water redistribution should be considered

D．water can be easily carried through pipes across the world

小題3:The text is mainly about________.

A．water supply and increasing population

B．water shortages and environmental protection

C．water redistribution and wildlife protection

D．water use management and agriculture

Answer 1

小題1:B
小題2:C
小題3:D

文章主要講述了水資源的管理和農(nóng)業(yè)的問題。
小題1:B 推理題。文章談?wù)摿怂�資源管理方面存在的嚴(yán)重問題，那么接下來應(yīng)該是討論解決問題的具體方法。
小題2:C 推理題。根據(jù)文章前兩段可知全世界存在著嚴(yán)重的水短缺的問題，那么降雨豐沛的國(guó)家應(yīng)該是副詞的幸運(yùn)。故C正確。
小題3:D 主旨大意題。文章主要講述了水資源的管理和農(nóng)業(yè)的問題，故D正確。
