Después de aprender Must vs Have To, en está lección aprenderás Future Perfect Continuous.
El Future Perfect Continuous, también llamado a veces el futuro perfecto progresivo, es un tiempo verbal que describe acciones que continuarán hasta un punto en el futuro. El futuro perfecto continuo consiste en will + have + been + the verb’s present participle (verb root + -ing).
Cuando describimos una acción en el Future Perfect Continuous, nos estamos proyectando hacia adelante en el tiempo y mirando hacia atrás a la duración de esa actividad. La actividad habrá comenzado en algún momento del pasado, presente o futuro, y se espera que continúe en el futuro.
Examples:
- In November, I will have been working at my company for three years.
- At five o’clock, I will have been waiting for thirty minutes.
- When I turn thirty, I will have been playing the piano for twenty-one years.
- By the end of this year, I will have been living in Aguascalientes for 4 years.
- By July of next year, Bill will have been working in the same company for 25 years.
- The students will have been studying English for 10 months by December.
- By 3pm, I will have been waiting for you for 2 hours.
Questions:
- How long will you have been working on your project by the end of this year?
- How long will you have been studying English by the time you travel to USA?
- By the end of this class, what will you have been doing all morning/ evening?
Nonaction Verbs Do Not Use the Future Perfect Continuous
Recuerde que los verbos sin acción como ser, parecer o conocer no son adecuados para el futuro perfecto continuo. En cambio, estos verbos toman el futuro perfecto, que se forma con will + have + past participle.
