问题 PASSAGE TWO
What is the reason for asbestos’ being in extensive use at present?

选项

答案Because of its availability and low cost.

解析 题目问的是目前石棉被广泛使用的原因。根据对文章大意的把握可将答案定位到首段最后一句:虽也可使用其他替代材料,但由于石棉使用方便、价格低廉(because of its availability and low cost),所以将继续在英国建筑业发挥主要作用。由此可知本题答案为Because of its availability and low cost。
