PRESENT PFECT TENSE WITH FOR AND SINCE.
Introduction.
We use present perfect tense to talk about action which started in the past and continues up to the present. For and since are used with the present perfect to indicate time. We use for+a period of time when consider the duration, or by considering its starting point, with since+a point in time.
For+a period of time.
We use for to talk about a period of time (a few days, half an hour, two years...)
Examples,
I have worked here for five years.
She has lived here for twenty years.
We have taught at this school for a long time.
Alice has been married for three months.
They have been at the hotel for a week.
Since+a point in time.
We use since to talk about a specific point in time, or a time when the action started (last year, June 8, 9 o’clock, since this morning, since last week, since yesterday..)
Examples,
I have worked here since 1990. She has lived here since 1980.
We have taught at this school since 1965.
Alice has been married since March 2nd.
They have been at the hotel since last Tuesday.
Note: for and since can be used with the past perfect.
Since can only be used with perfect tenses, for can also be used with the simple past.
LESSON 8.
BRITISH ENGLISH AND AMERICAN ENGLISH.
Although technically we all speak the same language (English), there are many differences between British English and American English:
Pronunciation – Although the word might be spelt the same, it is possible that people from the UK and America pronounce it differently. E.g. the word ‘tomato’ is pronounced ‘tom - ah- to’ in the UK but ‘tom - ay- to’ in the USA and the word ‘mobile’ is pronounced ‘mow - bile’ in the UK but ‘mow - bl’in the USA.
Spelling – There are a few major spelling differences between British and American English. This is because British English has generally kept the spelling of words that it has taken from other languages but American English has changed the spelling to look more like how the word actually sounds when you say it.
