Adults|Grammar|Intermediate|11. I have done and I did

Study this example situation:

Read the rules

The present perfect (something has happened) is a present tense. It always tells us about the situation now. «Tom has lost his key» = he doesn’t have his key now (see Lesson 5).

The past simple (something happened) tells us only about the past. If somebody says «Tom lost his key», this doesn’t tell us whether he has the key now or not. It tells us only that he lost his key at some time in the past.

Do not use the present perfect if the situation now is different. Compare:

1. They‘ve gone away. They’ll be back on Friday. (they are away now)

They went away, but I think they’re back at home now. (not They’ve gone)

2. It has stopped raining now, so we don’t need the umbrella. (it isn’t raining now)

It stopped raining for a while, but now it’s raining again. (not It has stopped)

Read the rules

You can use the present perfect for new or recent happenings:

1. «I‘ve repaired the TV. It’s working OK now.» «Oh, that’s good.»

2. Have you heard the news? Sally has won the lottery!

Use the past simple (not the present perfect) for things that are not recent or new:

1. Mozart was a composer. He wrote more than 600 pieces of music. (not has been… has written)

2. My mother grew up in Scotland. (not has grown)


1. Do you know that somebody has invented a new type of washing machine?

2. Who invented the telephone? (not has invented)

Read the rules

We use the present perfect to give new information (see Lesson 5). But if we continue to talk about it, we normally use the past simple:


— Ow! I‘ve burnt myself.

— How did you do that? (not have you done)

— I picked up a hot dish. (not have picked)


— Look! Somebody has spilt something on the sofa.

— Well, it wasn’t me. I didn’t do it. (not hasn’t been … haven’t done)


Complete the sentences using the verbs in brackets. Use the present perfect where possible. Otherwise use the past simple.


Put the verb into the correct form, present perfect or past simple
