Dear teachers:
I'm confused about four grammers.
"S+have/has+been+Ving" & "S+have/has + P.P."
"S+will / shall have + P.P." & "S+will / shall have been + V-ing"
I know the difference in them but I don't really understant how to use them correctly.
Can you tell me how to ues them ?
Thank you for your help
