问题     The pollution of Hong Kong’s beaches by oil from a damaged tanker last year recalls a similar incident which took place in Britain in 1967 when the Torrey Canyon, a huge oil tanker, split in two and caused disaster in coastal areas. Shoals of fishes were killed, sea birds hopelessly fouled with oil and coastal holiday resorts put out of business for several weeks. As a result of this particular incident scientists are becoming restless at the thought of Britain’s inability to cope with national disasters on a large scale. The reason for their concern is that technology is rapidly outstripping (超越) man’s ability to control it.
    Oil tankers, for instance, have been allowed to get bigger and bigger without sufficient thought being given to emergency braking and maneuvering arrangement. Collisions at Sea continue, but little effect has been made to develop safety devices as effective as those used for aircraft.
    Scientists were outspoken in expressing their concern during a recent meeting of the British Association. Unanimous approval was voiced when the leading speaker urged that a permanent national rescue services should be established, equipped for any emergency and ready to move off immediately.
    of all the possible disasters mentioned, the one promoting most discussion was a major release of radioactivity from a nuclear power station. one does not need a particularly vivid imagination to visualize the other possibilities discussed. What would be the effect of a jumbo-jet crashing on a large chemical plant handling destroying liquids? Could the tapping of natural gas lead to any form to collapse? Suppose a lorry full of a highly poisonous chemical crashed unseen into a large reservoir? Dams can burst, abnormal conditions can lead to massive electrical blackouts.
    An intensive study of such possibilities could at least reduce the effects of future disasters. For example, it would mean that a number of technical alternatives (such as the choice between detergent or chalk for dispersing oil) could be examined and tested in advance so that specially trained expert would know exactly what action was needed in a given emergency. [br] The main idea of the final paragraph is that______.
选项 A、in an emergency all the technical alternations should be studied
B、experts should be specially trained to determine the exact difference between detergent and chalk
C、we ought to decide what measures to take before a disaster occurs
D、technical experts should be examined and tested to see whether they are capable of selecting the right course of action in a future emergency
答案 C
解析 主旨大意题。最后一段的核心内容在于最后一句话“it would mean that a number of technical alternatives(such as the choice between detergent or chalk for dispersing oil) could be examined and tested in advance so that specially trained expert would know exactly what action was needed in s given emergency(这就意味着，许多技术方面的选择，诸如是选择洗涤剂还是白垩来去除油污，可以提前进行研究和测试，以便经过专门培训的专家可以准确地了解在紧急情况下应该采取何种行动) ”。根据这句话，可以看出A) 选项中的all the technical alternations与事实不符，而B) 和D) 的陈述有明显的错误。
