Present perfect (I have done) 1

به این مثال توجه کنید:

Tom is looking for his key. He can’t find it now.

He has lost his key.

He has lost his key.”"  معنی این جمله این است که کلیدش را از چند دقیقه قبل گم کرده و هنوز پیداش نکرده است.

This is the present perfect (simple) tense:

I/we/they/you have (=I’ve, etc.) lost.     

He/she have (=he’s, etc.) lost.              

  I (etc.) haven’t lost.         He/she hasn’t lost
Have you (etc.) lost?      Has he/she lost?
