常见错误Common mistakes
易错句子The dregs of the coffee is at the bottom of the cup.正确表达The dregs of the coffee are at the bottom of the cup.
dregs 表示“残渣、沉渣”时是复数名词，作主语时谓语必须用复数 are。汉语“残渣”没有单复数区别，学习者容易误用单数 is。
易错句子The dregs are on the bottom of the cup.正确表达The dregs are at the bottom of the cup.
表示某物在容器内部的底部要用介词 at（at the bottom of），不能用 on；on 强调贴在某个表面上，不表示“在……内部底端”。
易错句子He left many dregs in the cup.正确表达He left some dregs in the cup.
dregs 指不可数的残余物，虽用复数动词，但不能用 many 这类可数数量词，要用 some 等表示不确定数量的词。
