COuld anyone say to me the meaning of "cover story". It seems it is referred to journalism world, a kind of report, article or the like.
Yes, you are correct. It's used in journalism. It's the story that is promoted by the biggest headlines and pictures on the cover.
To take a simple example, let's say Drew Barrymore is on the cover of People magazine, and it has the headline (along with many other smaller ones) Drew: Happy at Last! The cover story is the one about Drew Barrymore.
Or Time may show an artists drawing of the plant on fire, and the cover story is about global warming.
