In Toeic test, Part 1 shows a picture to testers, and they instruct to pick up an appropriate description. A picture shows that a man wears clothes, and several examples described are provided like the following.
#1. A man is putting on a jacket.
#2. A man is wearing a jacket.
#2 of two is a correct answer. As everyone knows, #1 expresses the ongoing of action. #2 expresses the state of completed action. I don't know the situation is well described though.
As you know, Be verb + ing shows that ongoing action is happening, but #2 shows the state in contrast with the same form. I want to know the reason for the difference and which verbs there are to the expression of the state.
