please could you explain to me where to use open/opened, close/closed?
Thanks a lot.
The park is open. why not opened?
The park is closed. why not close?
I thought that "The park is closed." means The park is closed now [current status = present tense].
I see, as a [past action = past tense], e.g. this "The park was/has closed.".
Sorry for bothering,
"Closed" in this sentence is an adjective describing the status of the park.
The closing of the park took place in the past, even though the statement is in the present - It is closing = present action; It is closed = past action, stated now and indicating the status of the park.
When you close a park, it is closed. It has been closed, but that's not the point.
When you open a park, it is open. It has been opened, but that's not the point either.
The forms of the adjectives are different. That's the confusion.
