Present Perfect vs. Present Perfect Continuous
The use and the structure:
Present perfect is used to:
- Talk about situations which started in the past and they still last
- Focus on the result not the time which was devoted to completing the action
- Talk about our experience
- Say that something has just been done
Subject + have/has + past participle (III column) / a verb with –ed ending.
I have read this book 3 times already.
b) Present Perfect Continuous is used to:
- to show the length of the action
- to show the action is continued
Subject + have/has + been + a verb with –ing ending
