问题 Fungi are important in the process of decay, which returns ingredients to the soil, enhances soil fertility, and decompose animal debris.

选项

答案decompose—decomposes

解析 译文:腐殖化作用使各种成分回归到土壤中、增强土壤的肥沃性并分解动物的残骸。真菌在腐殖化的过程中起着重要作用。
分析:考查并列结构。本题中的and连接了并列的谓语部分。and前用了returns和enhances,它后面也应与之一致,用第三人称单数的decomposes。另需注意fungi是fungus的复数形式。
