Look carefully at these 2 sentences.
仔细看下面这两个例句。
He smells of fish.

He’s smelling the fish.

The second sentence is an action – not a state. The man wants to know if the fish is OK to eat.
第二句是一个动作——不是一个状态,那人想知道鱼是不是可以吃的意思

Sorry, what did you say? I was thinking about my holiday.
The first sentence is an opinion but the second sentence is an action.
第一句是一个意见,而第二句是一个动作。
