Cross, ugly, sour, and moody can all describe a bad mood. Cross is a mild, brief annoyance, often with children. Ugly describes a mood or crowd turning hostile. Sour describes bitterness after a disappointment. Moody describes unpredictable mood swings. Ugly 'unattractive' is not compared.

这四个词都可以表示情绪或气氛不好，但程度和语气不同：cross最轻微、短暂，ugly最强烈、带有敌意甚至暴力的意味，sour是失望后留下的怨恨和不快，moody则是反复无常的性格特点。这里不比较cross的“交叉、横过”义，ugly的“丑陋（外貌）”义，以及sour的“酸的（味觉）”义。
