For past events with a connection to the present

The present perfect tense is quite complicated to explain. It is used when an action that happened in the past continues to have a strong connection in the present. The best way to understand it is to look at some examples. They are followed in each case by a short explanation:

I have lost my dictionary. (I don't have my dictionary now; can you help me find it?)

Mary has fixed my computer (My computer is working now and I'm happy about it!)

You haven't eaten very much. (Don't you feel well? Don't you like it?)

I haven't read his letter. (I haven't had time yet. What does he say?)

Have you seen my calculator? (- I want to use it now!)

Has she had an accident? (- Someone said she's in hospital!)

Have you done your homework? (- It's due today!)
