     UNIDAD 7


   Ponga los verbos entre paréntesis en la forma adecuada.


1. El presente perfecto simple se forma con have + participipio de pasado. En la tercera persona del singular empleamos has en vez de have. Si el verbo es regular, el participio de pasado se hace añadiendo -ed al infinitivo2; pero si es irregular, hay que estudiarse la lista de la unidad 9.

   Veamos ahora la conjugación de un verbo regular y de otro irregular para ilustrar mejor esto:
   work (trabajar→regular)
   I have worked (he trabajado)
   you have worked
   he has worked
   she has worked
   it has worked
   we have worked
   you have worked
   they have worked

   sing (cantar→irregular)
   I have sung (he cantado)
   you have sung
   he has sung
   she has sung
   it has sung
   we have sung
   you have sung
   they have sung

   La formas de arriba se contraen de la siguiente manera: quitamos ha, y ponemos un apóstrofo en su lugar:
   work (trabajar→regular)
   I've worked (he trabajado)
   you've worked
   he's worked
   she's worked
   it's worked
   we've worked
   you've worked
   they've worked

   sing (cantar→irregular)
   I've sung (he cantado)
   you've sung
   he's sung
   she's sung
   it's sung
   we've sung
   you've sung
   they've sung

   En la negativa, se pone not detrás de have/has. En la interrogativa, have/has va delante del sujeto.
   He has worked today. (afirmativa » Ha trabajado hoy.)
   He has not worked today./He hasn't worked today. (negativa)
   Has he worked today? (interrogativa)
   We have sung two songs. (afirmativa » Hemos cantado dos canciones.)

3. El presente perfecto simple se usa para acciones que empezaron en el pasado y que se remontan hasta el presente. El presente perfecto simple está conectado con el presente, pero el pasado simple no tiene ninguna conexión con el presente. Ejemplos:

13. El pasado perfecto simple y el continuo son los pasados del presente perfecto simple y el continuo. Por lo tanto, las reglas que acabamos de mencionar para los tiempos presentes se aplican a sus respectivos pasados.

   He has been singing. (presente perfecto continuo » Ha estado cantando/Lleva cantando.)

   They had never been to London. (pasado perfecto simple » No habían estado nunca en Londres.)
   He had been singing. (pasado perfecto continuo » Había estado cantando/Llevaba cantando.)

   Además de esto, hay que tener en cuenta que el pasado perfecto (ya sea simple o continuo) es más pasado que el pasado simple o el continuo. Esto lo podemos representar de la siguiente manera:
   — — — ↓ — — — — — ↓ — — — — ↓ — —
   (pasado perfecto) ← (pasado) ← (presente)

   Veamos los ejemplos de abajo para ilustrar mejor este punto:
