SECOND CONDITIONAL

El segundo condicional se usa para expresar la consecuencia de una acción o situación irreal en el presente o futuro. 

EJEMPLO:

• If I won the lottery, I would travel around the world.
• If I had more free time, I would play more sport.

Para hacer una oración en el segundo condicional, usamos:

If + past simple, would/wouldn’t + verb.

• If I lived in a big city, I would go out more often.
• If I lived in a big city, I wouldn’t need a car.

Como con todos los condicionales, también puedes invertir esta estructura:

• I’d go out more often if I lived in a big city.

THIRD CONDITIONAL

El tercer condicional se considera un condicional irreal, puesto que se refiere al pasado, pero no a lo que realmente ocurrió, sino a lo que podría haber ocurrido y a cómo ese hecho habría tenido otras consecuencias:

EJEMPLO:

• If I hadn't gone to Marta's party, I would never have met my wife 
• If I had studied the right things, I would have passed that exam 

Por ese carácter irreal, solemos utilizar este condicional para hablar de nuestros arrepentimientos, de las cosas que, vistas en perspectiva, habríamos hecho de otra manera:

EJEMPLO:

• If I hadn't gone to the casino after the Christmas party, I wouldn't have lost all my money

O de las oportunidades perdidas:

• If I had done an Erasmus programme in the UK, my English would have improved

2. if we had all remembered to close the windows in the house, none of the furniture would have been damaged by water.

3. if i had asked first where there were promotions, i would have taken advantage of the mall discounts.
