Third Conditional

E se o passado pudesse ser diferente? O Third Conditional é a chave para viajar no tempo com as palavras! Ele expressa arrependimentos, alívios ou sonhos sobre o que poderia ter acontecido, mas não aconteceu. Use para imaginar um passado alternativo: “E se eu tivesse feito diferente?” – e descubra o resultado com would have. 

Vamos começar lembrando que o Third Conditional (Terceiro Condicional) é usado para falar sobre situações hipotéticas ou irreais no passado.

Sua estrutura é formada por duas orações: a oração condicional é introduzida por if + past perfect, e a outra oração é formada por would have/wouldn’t have + past participle. 

If she had studied, she wouldn’t have failed the test
(Se ela tivesse estudado, ela não teria reprovado na prova)

If + past perfect / wouldn’t have + past participle

had studied: past perfect (verbo to study no passado perfeito)

wouldn’t have failed: would have + past participle (verbo to fail no particípio passado)

Quando a oração começa com if, ela é separada da segunda oração por vírgula. Caso contrário, não há vírgula.

She wouldn’t have failed the test if she had studied
(Ela não teria reprovado na prova se tivesse estudado)

If I had gone to the beach, I would have made sandcastles
(Se eu tivesse ido à praia, eu teria feito castelos de areia)

If + past perfect / would have + past participle

had gone: past perfect (verbo to go)

would have made: would have + past participle (verbo to make)

I would have made sandcastles if I had gone to the beach
(Eu teria feito castelos de areia se tivesse ido à praia)

If I had seen Mark, I would have talked to him
(Se eu tivesse visto o Mark, eu teria conversado com ele)

If + past perfect / would have + past participle

had seen: past perfect (verbo to see)

would have talked: would have + past participle (verbo to talk)

I would have talked to Mark if I had seen him.
(Eu teria conversado com Mark se o tivesse visto)
