问题 An area several times as large is suffering a decline in productivity as it is________ by overuse.
选项 A、depressed
B、defaulted
C、deteriorated
D、degraded
答案D
解析 逻辑关系题：因果。[D]degraded “降级，退化”，常指使某物价值、质量等降低、降级，或坏的习惯和行为毁坏某人的品格，使他堕落或地位降低，如 to degrade oneself by cheating and telling lies (因欺骗说谎而自甘堕落)。句子当中是说过度使用使这块土地退化了，并且 degraded 与 decline 形成同义关系。[A] depressed“使沮丧，压下”，指使事物活力、效力等下降，或使人心情沮丧消沉; [B] defaulted “不履行责任，不履行契约”，如 default a loan(不偿付贷款)；[C] deteriorated “恶化，变坏”，通常指关系或病情等恶化。
