Welcome to English in a minute! When you listen to American English, you will probably hear this idiom: SLEEP LIKE A ROCK. How dose a rock sleep? Let’s listen: Sleep like a rock 睡得安稳 A: I remember you said you were getting a new bed last weekend. How do you like it? B: I love it! My old bed totally bit the dust, but the new mattress is great. I slept like a rock last night. A: That's good to know. I have not been sleeping well at all lately. Maybe I should think about getting a different mattress, too. If you slept like a rock, you slept very well. You can’t wake a rock, because it’s not alive. You can also say you slept like a log to mean the same thing. And that's English in a Minute.
