1. The prisoner is being released.

2. The prisoner will learn some skills after being released.

In sentence 1 , is is being released an example of the passive continuous tense?

In sentence 2, is being the main verb and released an adjective complement? if not how are these two words functioning?

Thank you.

CarewIn sentence 1

It is present continuous tense, passive voice.

CarewIn sentence 2

It is a non-finite (gerundial-participial) clause, the object (complement) of the preposition "after".

Here are some other examples (active voice).

After eating breakfast, we got ready for school.
After running a mile, she was exhausted.
Mom watched TV after doing the dishes.

(passive voice)

After being repaired, the car looked good.
After being red-carded in three games, the footballer was kicked off the team.

CarewThe prisoner will learn some skills after being released.

'after' is one of several subordinators which can be followed by a participle clause. The subject of the participle clause is implicitly the subject of the main clause. Therefore, 'being' in this clause is a substitute for 'he is' or 'he has been'. 'he' comes from 'the prisoner' and an appropriate tense must be chosen for the paraphrase because participles have no tense. So an equivalent sentence is this:

The prisoner will learn some skills after he has been released.


Rockford has been on the school board since being appointed in 2015.
(since he was appointed)
Unfortunately, he died before seeing the Health Care Bill passed in Congress.
(before he saw)
Although spending millions on attack ads, the candidate is still far behind in popularity with state voters.
