Dear teachers,<br/><br/>Would you be so kind to explain how differently would you feel about these two?<br/><br/>1. I have practiced the piano for an hour.<br/><br/>2. I have been practicing the piano for an hour.<br/><br/>My guess is,<br/><br/>1. ............and that is enough for today.<br/><br/>2. ............and I want to continue more.<br/><br/>This guess might fit in some situation,<br/><br/>but, they might not be always like this........<br/><br/>How would you choose differently<br/><br/> 1. have + pp(past participle) <br/><br/> and <br/><br/> 2. have been ***ing(present participle)<br/><br/>in your daily life?<br/><br/>Is there any clear key to distinguish between these two?<br/><br/>Warmest regards,<br/><br/>blissfarm
