高考英语阅读练习题及答案

　　Mr, Jonhs was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers.

How astonished the customers were to discover that he was not burned at all. You can well imaging that he had increasing business in asbestos roofing materials.
