The difference between lay and lie is subtle, and even native speakers will often get thetwo confused.
What's the difference? When you laysomething down, you are acting on an objectand setting it down. For example, you lay ablanket on the bed. When you lie down, you, the subject, are assuming a horizontalresting position. Since there is no objectbeing acted upon, you lie down on the bed.
Lay和lie的區別很微妙，就算是母語英語的人也經常搞混。
有什麼區別呢？你如果lay某物，你就是把某個物體放下。比如說你lay一個毯子在床上。而你lie，就是自己作為受力物體在保持水平的姿勢。既然lie的受者是自己，所以就是自己躺在床上。
