FOR, DURING, WHILE.

CÓMO Y CUÁNDO UTILIZAR FOR, DURING O WHILE.
Estas tres palabras se usan para expresar "períodos de tiempo" y, básicamente,
se traducen como FOR (durante), DURING (durante) y WHILE (mientras). Y el hispanohablante suele tener dudas acerca de cuándo utilizarlos correctamente.


FOR and DURING
Se usa FOR + período de tiempo para expresar cuánto tiempo dura algo. Observa estos ejemplos:

We watched televisión for two hours last night.Miramos televisión durante dos horas anoche.
Eliza is going away for a week in May.
Eliza se va durante una semana en mayo.
Where have you been? I've been waíting for ages.
¿Dónde  has estado? He estado esperando (durante) añares.

Se usa
DURING + sustantivo para expresar cuándo algo sucede (no "cuánto tiempo dura"). Observa estos ejemplos:

I fell asleep during the movie.
Me quedé dormido durante la película.
We met a lot of nice people during our vacation.

Conocimos mucha gente interesante durante nuestras vacaciones.
The ground ís wet. It must have rained during the night.
El suelo está humedo. Debe haber llovido durante la noche.

 
Recuerda entonces que no puedes usar during para expresar cuánto dura algo (como ocurre en español). Presta atención:
CORRECTO 
  >>   It rained for three days.INCORRECTO >>  It rained during three days.

DURING and WHILE
Como ya has visto during se usa con la estructura during + sustantivo. Por el contrario while se usa con la estructura while + sujeto + verbo. Observa estos ejemplos:

I fell asleep during the movie.Me quedé dormido durante la película.
the movie = NOUN

I fell asleep while I was watching the movie.Me quedé dormido mientras estaba mirando la película.
I + was watching = SUBJECT + VERB

Otro ejemplo utilizando ambas versiones:

We met a lot of interesting people during our vacation.
Conocimos mucha gente interesante durante nuestras vacaciones.
We met a lot of interesting people while we were on vacation.
Conocimos mucha gente interesante mientras estábamos de vacaciones.
