问题 Nuclear power plants are some of the largest producers of______ wastes, with each plant producing barrels of radioactive material that must be stored in special protective containers.
选项 A、biodegradable
B、hazardous
C、reasonable
D、durable
答案B
解析 B选项：hazardous的意思为“危险的，危害的”，如：These conditions arevery hazardous for shipping．(这些情况对航海非常不利。)句意：核电站是某些有害废物的最大制造者。每一个核电站产生成桶的放射性物质，必须存放在专门的防护容器里。故选B。其他三项意思分别是：biodegradable能进行生物降解的；reasonable合理的，适度的；durable持久的，耐用的。
