[FW] Why cannot I use the current finished mode for die?

Have pp indicates that "everything has been done since now ".

MR. CHEN has taught English for 30 years. --- indicates that the teach operation lasted for 30 years,
MR. CHEN has died for 30 years. --- it's done! MR. CHEN Cannot Die. Die again the next day until today!

Dead can be used to describe the word "death", and "delayed". Before describe the word, it must be an animated word. Therefore, "death" must be replaced
MR. CHEN has been dead for 30 years

The act of "wedding" is also the same. You cannot perform the "wedding" operation every day! After a person is "married", it is the "Married" legal representative, which can be maintained every day, so
Mr. And mrs. Chen have been married 20 years.
