易错句子The delay compounded by the bad weather.
正确表达The delay was compounded by the bad weather.
汉语没有动词的被动形态变化，学习者容易漏掉被动语态的助动词。这里 delay 是被坏天气“加重”的，需要用被动结构 be + 过去分词，即 was compounded；只写 compounded 会让句子缺少谓语，读起来像名词短语。

易错句子The heavy rain compounded with the traffic jam.
正确表达The heavy rain compounded the traffic jam.
compound 表示“使（问题、困难等）恶化”时是及物动词，后面直接跟宾语，不加介词。with 是受汉语“和/与……”或 combine with 的影响误加的，去掉 with 后 compound 直接带宾语 the traffic jam 才符合该词义的结构。

易错句子The committee compounds of ten members.
正确表达The committee is composed of ten members.
compound 的词义是“把不同成分混合成一体”，并不表示“由……组成/构成”。表示整体由若干部分构成要用 be composed of（或 consist of）；把 compound 当作 compose 使用，既不合词义也用错了结构，因此改为 is composed of。
本组反义词对应 compound 作动词、意为“使（问题/困难）加重、恶化”的义项。表示减轻、缓解或改善负面情况；若要表达“混合”义，反义概念是 separate 等，不在此组。
