گذشته ساده:
زبان عمومی و اختصاصی
past simple
to talk about single past completed actions. Often the time is mentioned:
A few weeks ago a woman called to report a robbery at her house.
But no time reference is necessary if it is already known:
How did the burglar break in without anybody hearing him? (in the story I just told you about)
to give a series of actions in the order that they happened:
The burglar came in through the front door, picked up the woman’s handbag, emptied it out, and stole her purse.
گذشته استمراری:
زبان عمومی و اختصاصی
Past Continuous
We use the past continuous
to provide the background scene to an action or event (usually in the past simple). We often use words like when, while, and as:
It happened at five in the afternoon while she was watching the news on TV.
He was doing his homework in his bedroom when the burglar came into the house.
It is possible to have more than one background scene happening at the same time:
He was doing his homework in his bedroom while I was reading an article.
کاربرد used to و would برای عادت و تکرار در گذشته:
زبان عمومی و اختصاصی
We use used to + infinitive or would + infinitive (contracted to ‘d in spoken English) to talk about past repeated actions:
She used to keep the front door locked, (but she stopped doing this)
She would leave the door unlocked whenever she was at home.
“Would is unusual in the negative form and in Yes/No questions.”
-We use used to + infinitive to talk about permanent situations that are usually no longer true:
Bill Murphy used to work for the police force, (but he doesn’t now)
not Bill Murphy would work for the police force.
-We do not use used to if we want to talk about how long the situation lasted:
Bill Murphy worked for the police force for over 17 years,
(not Bill Murphy used to work for the police force for over 17 years.)
