have + been + v(ing) = present prefect progressive have + been - v(ed) - ? what is this?

have + been + ~ing = the present perfect progressive tense in the active voice
have + been + ~ed = the present perfect tense in the passive voice

the passive voice vs. the active voice
All full-time colleagues "have been informed." = Someone "has informed" all full-time colleagues.
A man "has been arrested." = The police "have arrested" a man.
The owner of the jewelry "has been informed."= Someone "has informed" the owner of the jewelry.
The jewelry "has been damaged."=Someone "has damaged" the jewelry.

When the doer is not important or you do not want to mention him, your sentence can be written in the passive voice.

eg:-He was driving too quickly and killed.
This pattern is used to form progressive,may be passive voice in verb.
eg:-KITTY is being punished in classroom.
eg:-KITTY was being questioned at a police station in Taipei.
eg:-Government has been complained about the Economic recession TW.
eg:-Air and sea rescue operation has been going on (searched all night) for the crew of a fishing trawler which sank in the Taiwan Strait(Channel)..
