You also use the same past participle form to make a PASSIVE sentence. Look at these examples:
An active sentence (the subject of the sentence "does" the verb..)
Bees make honey.
A passive sentence:
Honey IS MADE by bees.
If you know the names for certain grammatical terms in English, the DIRECT OBJECT of the verb (HONEY) goes to the subject place, you put a form of the "to be" next, and that verb is in THE SAME TENSE as the original active sentence, and then you put the PAST PARTICIPLE form of the verb next. Finally, what was originally the subject of the sentence (Bees) goes to the end of the sentence with the word "by" in front of it.
One of our presidents used the passive form of a sentence to his advantage. If he had said the active form of the sentence, he would have said,
"I made mistakes."
You can avoid taking responsibility for your actions by using the passive form of a sentence, because you do not always have to include the original subject if you don't want to.
The PASSIVE form of the sentence "I made mistakes." would be "Mistakes were made BY ME."
