摘要： keep doing/keep on doing (1)keep doing侧重表示"持续不停地做某事"或"持续某种状态".如: The girl kept crying all the time. 那个女孩一直在哭. The baby kept sleeping about four hours. 这个婴儿连续睡了大约四个小时. (2)keep on doing 表示"总不断做某事".不表示静止状态.不能与sitting, sleeping, lying, standing这类 词连用.如: It kept on raining for seven days. Don't keep on asking such silly questions.
