军队职称英语考试C级补全短文考点：Fire-Fighting Fabric
Each year thousands of people worldwide are killed or seriously injured by fires started in mattresses.46.To help prevent fires in crowded public spaces，E.I.Du Pont de Nemours&Co.recently invented a fire resistant fabric（防火织物）。The company claims that this fabric significantly reduces the combustibility（易燃性）of mattresses and upholstered（装有套子或垫子的）furniture.In tests conducted by a Boston-based hotel chain，the material has proved very efficient in preventing or delaying the combustion of mattresses and furniture after fires have been started.47.California and several other states are considering new regulations that would require the use of fire-resistant furniture in public places（defined as area where 10 or more people gather）。48.American laws require hotels to buy fire-resistant mattress covers，though covers made of fiber glass（纤维玻璃）and cotton do exist and are used by some companies.49.
