Using the present and past participles as adjectives

Today, you learnt that the past participle form can be used in the following ways:

(1) in the past perfect tense (had + past participle)
e.g. He watched television after he had completed his homework.

(2) in the present perfect tense (has/have + past participle)
e.g. I have completed my homework.

(3) in the passive form (is/are/was/were/- been + past participle)
e.g. All the apples were eaten by the hungry boy.

(4) as adjectivies (past participle + noun)
e.g. The poor trapped rat is squeaking loudly.

The present participle form can also be used as an adjective.
(present participle + noun)
e.g. What amazing feats the acrobat is capable of!
