问题 Exposure to asbestos fibres can cause cancer ______.
Exposure to asbestos fibres is harmful to people’s health ______.

选项 A、so the use of asbestos is limited
B、but asbestos will continue to be used for a long time to come
C、so other new kinds of materials are under development
D、but they will not be so when ventilation devices are used

答案B

解析 事实判断题。第二段第四句指出,报告同时也认为,虽然已有了其他建筑材料,石棉在英国建筑业未来的许多年中将继续起重要作用,因为它易得到且成本低。"so the use of asbestos is limited"与"but they will not be so when ventilation devices are used"都不对,因为即使如此,石棉对人仍有伤害。全国医学研究会所给的一些建议只能减少(reduce)石棉绒对人体的伤害,却不能杜绝,见第三段第一句。"so other new kinds of materials are under development"也不对,其他材料业已存在,而不是正在研制(under development)。
