USO
Em um contexto já situado no passado, usamos o Past Perfect para mostrar que a ação à qual nos referimos é anterior às que acontecem no texto.
Ex.: I was talking to her, and suddenly, I realised that we had met once before. Note que o Past Perfect deve estar sempre inserido em um contexto já no passado, ou sua utilização estará errada.
FORMA
O Past Perfect é formado pelo verbo auxiliar "have" no passado (had) e o Past Participle do verbo principal.
Ex.: Thomas had been terribly disappointed when he met her.
*Forma Afirmativa: When I arrived there, I saw that I had gone to the wrong place. They had lived in the same building for two years and didn't know each other.
*Forma Interrogativa Had you been there before? Had I worked with them?
*Forma Negativa I hadn't seen them until then. Hugh hadn't realized that the situation was so serious.

SINTESE: "BEYOND THE 20th CENTURY
O texto trata de ficções cientificas de livros e filmes com histórias baseadas em previsões sobre a vida no futuro.
Por mais óbvias que algumas previsões possam ser, elas não aconteceram.
O Almanaque do Futuro fez poucas previsões para o século 20, como por exemplo, que os livros irão ficar mais caros.
