PRESENT PERFECT SIMPLE vs PRESENT PERFECT CONTINUOUS

PRESENT PERFECT SIMPLE vs PRESENT PERFECT CONTINUOUS

http://www.aulafacil.com/Ingejerc/Lecciones/Lecc21.htm1.- Present perfect continuousEsta forma verbal se emplea cuando interesa destacar la accin en s misma ms que el resultado; no se precisa si la accin ha finalizado o no (la accin comenz en el pasado y puede que acabe de terminar o que incluso contine). I have been reading a book (resalto lo que he estado haciendo; no indico si he finalizado el libro o no) Este tiempo se utiliza tambin para indicar la duracin de una accin que comenz en el pasado (y que acaba de finalizar o an contina). I have been playing tennis for two hoursI have been waiting for him for 1 hour (puede que la otra persona acabe de llegar o que yo an siga esperando; el contexto determinar un sentido u otro)

El empleo de este tiempo indica que el emisor considera que la duracin ha sido larga. 2.- Present perfect simpleDescribe una accin que comenz en el pasado y que acaba de finalizar. Pone el nfasis en el resultado y no en la accin en si misma.I have read a book (destaco que he ledo un libro, que lo he terminado, y no el hecho de haber dedicado un tiempo a la lectura).

En el siguiente ejemplo se puede observar la diferencia entre estas dos formas verbales:I have done my homework (indico que ya lo he finalizado)I have been doing my homework (indico la actividad que he estado desarrollando; no informo de si he terminado mis deberes o no) Se utiliza tambin para indicar cuantas acciones se han realizado en un tiempo determinado. Today I have read ten booksEl empleo de este tiempo informa indirectamente sobre el presente, ya que conlleva que la situacin no ha cambiado. He has gone to Canada (esta persona sigue en Canda o est de viaje hacia all; en cualquier caso todava no ha regresado)I have broken my leg (la pierna sigue rota; an no ha sanado) Si no se da informacin sobre el presente hay que utilizar el "past simple". He went to Canada (no se informa de si l sigue all o ya volvi)I broke my leg (puede que la pierna ya est curada o que an siga rota) En aquellos verbos en los que no se utiliza la forma continua (leccin 17) hay que recurrir en todos estos supuestos al "present perfect simple". 1.- Escribe el verbo entre parntesis en "present perfect" o "present perfect continuous" segn corresponda:
