The first role i hope to know
is
when can u use (ed) and (ing) in ur studies
If you want to say any thing about any person , you should use adj + ed
for example: when i say >>>this person is so bore....i should use (ed) like bored
so when you discribe any body he is bore you can say . he is so bored
give this role for any adjective for persons
but
when i say about things >>i should use adj + ing
for example : this movi is so boring / exciting / facinating / interesting
