hello my name is ruthy
eventhough im not good at grammar but i can tell u some of that
present perfect simple is use to express and action from the past until now
and it has just finished.
eg. i have painted the wall blue ( that mean that i finish painting it already and now it is blue)
present perfect continuous is used to express and action from the past too but it is in progress now it hasn't finished yet.
eg. i have been painting the wall blue ( that mean that i started pain it at any time in the past but now i am still painting it. some part of the wall are blue but some still white)
but the same of this two tense is that happen in the past but have the present result
eg. it has rain here because the grown are wet.
it has been raining here because the grown are wet.
that two are the same.
that all from me. sorry in advance if there are any mistake
