问题     (1)In 1967, in response to widespread public concern aroused by medical reports of asbestos related death, the National Medical Research Council(NMRC)organized a committee of enquiry to investigate the health threats associated with the use of asbestos in the building industry. After examining evidences provided by medical researchers and building workers and management, the Council published a report which included advices for dealing with asbestos. The report confirmed the findings of similar research in the United States and Canada Exposure to relatively small quantities of asbestos fibers, they concluded, was directly responsible for the development of cancers, asbestosis(石棉沉着病)and related diseases. Taking into account evidence provided by economists and building industry management, however, the report assumed that despite the availability of other materials, asbestos would continue to play a major role in the British building industry for many years to come because of its availability and low cost.    (2)As a result, the Council gave a series of recommendations which were intended to reduce the risks to those who might be exposed to asbestos in working environments. They suggested that, where possible, asbestos-free materials should be employed. In cases where asbestos was employed, it was recommended that it should be used in such a way that loose fibers were less likely to enter the air. The report advised that special care should be taken during work in environments which contain asbestos. Workers should wear protective equipment and take special care to remove dust from the environment and clothing with the use of vacuum cleaner.
    (3)The report identified five factors which determine the level of risk involved. The state and type of asbestos is critical to determining the risk factors. In addition, dust formation was found to be limited where asbestos was used when wet rather than dry.
    (4)The choice of tools was also found to affect the quantities of asbestos particles that enter the air. Machine tools produce greater quantities of dust than hand tools and, where possible, the use of the latter was preferred.
    (5)A critical factor which takes place in risk reduction is the adequate ventilation of the working environment. When work takes place in an enclosed space, more asbestos particles circulate and so natural or machine ventilation should be used. By closely following these advices, it was claimed that exposure can be reduced to a reasonably practical minimum. [br] Which of the following statements is NOT the suggestion put forward by the NMRC?
选项 A、Special care should be taken when at work.
B、It is better for people to use asbestos-free materials.
C、The quantities of asbestos should be reduced.
D、Asbestos should continue to function for years.
答案 D
解析 第1段末句指出，未来石棉仍会在英国建筑业中发挥主要作用。这句话虽出自国家医疗研究理事会，但原文assumed一词表明这只是他们的一个论断，并不是他们提出的建议，D是本题答案。根据第2段可知，A、B都是NMRC提出的建议，均可排除。最后三段都是关于如何减少石棉颗粒，属于NMRC的建议，故可排除C。解答本题时考生要抓住题干的关键词suggestion，在理解全文大意的前提下，通过浏览选项很快便能得出正确答案。
