deep与deeply的用法区别两者均可表示“深”、“深深地”，修饰具体的动作, 有时可互换：The doctor asked me to breathe deep [deeply]. 医生叫我做深呼吸。修饰静止状态、介词短语或表示深夜等，通常用deep(偶尔也用deeply)：He sat there deep in thought. 他坐在那儿深思。The meeting continued deep into the night. 会议一直开到深夜。Karen and Dave are deeply in love with each other. 凯伦与戴夫俩人深深地相爱着。修饰带有感情色彩的动词(如 hate, dislike, love, admire, hurt, regret 等)，通常要用 deeply，另外，修饰形容词、过去分词等，一般也要用 deeply：He deeply hates fish. 他很不喜欢吃鱼。We deeply regret your misfortune. 我们对你的不幸深表遗憾。I am deeply grateful to you. 我衷心感谢你。He was deeply moved by [at] the story. 听了这个故事，他深受感动。
