3.Frequently asked questions
Present perfect vs past simple: what's the difference?
The past simple is for finished actions at a known time; the present perfect is for past actions linked to now, with no stated time. Compare "I saw that film last night" (the time is stated) with "I have seen that film before" (an experience, no time given). The present perfect also describes a period that is still going on: "She has lived in Paris since 2010" means she still lives there, while "She lived in Paris in 2010" is about a finished time.
Is it correct to say "I have seen him yesterday", or should it be past simple?
No, say "I saw him yesterday": finished time words like yesterday, ago, last week and in 2020 need the past simple, not the present perfect. The present perfect can't go with a stated finished time, so "They have finished the project yesterday" and "I have met your brother last week" are wrong. Use the present perfect when no time is given ("I have seen him") or with words that mean up to now, such as ever, never, before and so far: "Have you ever met him?"
Present perfect or past simple with "today", "this week" and "this morning"?
Use the present perfect while the period is still going on ("I have drunk three coffees today") and the past simple once it is over. This morning depends on when you speak: at 10 a.m. you can say "I have had two meetings this morning", but in the evening the morning is finished, so you say "I had two meetings this morning." The same logic works with this week, this year and this summer: "We have studied Spanish this year" means the year is not over yet.
"I have lived here for five years" or "I lived there for five years": present perfect or past simple with for?
Both are correct: "I have lived here for five years" means you still live here; "I lived there for five years" means you moved away. Use the present perfect for a period that continues up to now and the past simple for a finished one: "They have been married for 5 years" (still married), but "They were married for 5 years" (not any more). Questions follow the same rule: ask "How long have you lived here?" about now, but "When did you move here?" about a finished moment.
Is "I just ate" or "Did you eat yet?" correct, or do you need the present perfect?
Yes, "I just ate" and "Did you eat yet?" are correct in American English, where the past simple with just, already and yet is common. British English usually prefers the present perfect here: "I've just eaten", "Have you eaten yet?" Both are understood everywhere, and the present perfect is correct in both varieties. The rule for finished time words stays the same: say "I ate at noon", not "I have eaten at noon", in British and American English alike.
