Diferença entre Simple Past e Present Perfect

Hello guys!

Vou tentar ajudá-los com a diferença entre Simple Past e Present Perfect.
Como a teacher Fabi postou anteriormente, o Present Perfect é uma ação indefinida, enquanto que a ação no Simple Past já terminou.

SIMPLE PAST
Wolfgang Amadeus Mozart was an American musician and composer. He lived from 1756 to 1791. He started composing at the age of five years old and wrote more than 600 pieces of music. He was only 35 years old when he died.

Nós usamos o Simple Past para eventos especificos no passado. Mozart já passed away. Ele não vai mais compor música alguma, portanto, a ação está finished.

PRESENT PERFECT
Tom is looking for his keys. He can’t find it.
He has lost his keys. (He lost them and still can’t find them.)

Have/has lost é Present Perfect. Tom perdeu as chaves e ainda não as encontrou.

Hope I could help it. ;-)

Bye
Teacher Dri
