How to form the present perfect | Present perfect continuous

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!)
Forming the Present Perfect
Affirmative: Subject + Have / Has + Past Participle

Negative: Subject + Haven't / Hasn't + Past Participle

Question: Have / Has + Subject + Past Participle
With words of unfinished time
The present perfect tense is used with words or expressions of unfinished time. Unfinished time started in the past and continues into the present. (So, this week, for example, means all the days so far this week including today.) Here are some sentences in the present perfect. The expressions of unfinished time are shown in bold.
