e.g. I’ve made spaghetti for lunch. (i.e. there is spaghetti for lunch.) I haven’t done my homework. (i.e. I don’t have any homework to give you.) I’ve bought a new dress. (i.e. I have a new dress.) I’ve lost my keys. (i.e. I don’t know when or where I lost them, but I haven’t got them now.)
e.g. Did you use tinned or fresh tomato for the spaghetti sauce? I didn’t do my homework because I had to study for another exam. Where did you buy the dress? When did you last use your keys?
e.g. That’s £30, please. - Sorry, did you say £30 or £13?
e.g. I’ve had three exams this week.
and sometimes implied, especially with ever and never :
e.g. Have you ever been to Greece? (i.e. at some time in your life ) - No, and I’ve never been to Italy either.
But be careful with the implied time reference:
e.g. (At 3 p.m.) I’m hungry. I haven’t had lunch. but (At 9 p.m.) I’m going to have a big dinner. I’m very hungry because I didn’t have lunch today. (Today still continues but lunchtime has finished.)
e.g. Peter has just phoned. (But to talk about the details, as always, we continue in the Past Simple: What did he want? - He said he can’t come this evening. )
e.g. Don’t buy any butter this afternoon. I’ve already bought some.
It’s too early to go out. I haven’t had breakfast yet. (I’m going to have it now.) Have you seen The Iron Lady yet? (I know you go to the cinema every week, so I’m sure you’re going to see the film some time.) Compare: Has John phoned? (I don’t know if he is going to phone.) Has John phoned yet? (Either he said he was going to phone, or he usually phones.)
N.B. All of the above reflects British usage. In many cases, the Americans use the Past Simple when the British use the Present Perfect.
We also use the Present Perfect to talk about the duration of actions which began in the past and continue in the present. For indicates the duration of the action and since the point in time when the action began:
e.g. I have a watch. I’ve had it for three years. I’ve had it since 2009. I think I have delirium tremens. I haven’t had a drink for three hours. I haven’t had a drink since lunchtime.
e.g. How long have you been here? - For half an hour / Since 9:30.
Notes
a. You cannot use the present simple in these cases, i.e. you must say I have known him for 3 years , not I know him for three years. b. You cannot use since ….. ago instead of for , i.e. you must say I have worked here for three years , not I have worked here since three years ago. c. You cannot use Since when …? instead of How long …? d. You can use a subordinate clause in the Past Simple after since , e.g. I have lived in this house since I was ten. e. Do not confuse How long ..? + Present Perfect with How long ago ..? + Past Simple. e.g. How long have you been here? - For half an hour. How long ago did you arrive? - Half an hour ago. f. You can only use since with the Present Perfect. For can be used with the Present Perfect for actions which are still continuing, and with the Past Simple for actions which have finished. Compare: Rajoy has been President of Spain for 4 months (and he is still President). He has been President since December. Zapatero was President of Spain for 7 years (but he isn’t President now). He was President from 2004 to 2011. g. Do not confuse for , which answers the question How long..? with during , which answers the question When..? e.g. When did Winston Churchill first become Prime Minister of Great Britain? – During the Second World War, in 1940 to be exact. How long was he Prime Minister? - For six years. h. We do not use for with expressions such as all day, all week etc. e.g. I’m very hungry. I haven’t had anything to eat all day.
N.B. British and American usage is the same with for and since.
A. Put the verb in brackets into the correct tense, incorporating adverbs in the correct place.
B. Translate into English:
