Why we use the present perfect?

           It helps us connect the past and the present. It allows us to talk about experiences and actions that started in the past but are relevant to now.

    It is a language teaching method developed by Dr. James Asher that coordinates language learning with physical movement. It mimics how children learn their mother tongue by having learners respond to imperative commands (e.g., "stand up") with actions, reducing stress and accelerating comprehension before requiring speech.
