Present perfect

Have/ has + past participle (worked, seen, etc)

We use the present perfect for past experience when we don't say exactly when they happened.

• We often use ever and never when we ask or talk about past experiences. They go before the main verb.

In American English, we use the present perfect and the simple past with yet and already.

• already is used in + sentences and goes before the main verb.
• yet is used wth - sentences and ?. It goes at the end of the phrase.

Well, no, it’s quite logical, but it does have different uses. We often use present perfect for talking about something which happened in the past which is important now.

 Let's take a look to this images with examples:

My Chinese teacher has given me some homework. (= I have the homework to do now.)

I’ve forgotten. (= I can’t remember now.)

She’s broken her leg. (= Her leg is still broken now.)

We also use present perfect with just for talking about a recent action.

 Sara’s just made a cake.
