Question

Commonplace acts and utterance of the child are praised and quoted.
change the voice

Answer 1

The active voice sentence of the given sentence is as follows:

Everyone praises and quotes the commonplace acts and utterance of the child.

This was an object implied case. In such cases we have to supply the object from our side. The object becomes the subject in active voice. In this sentence we supplied the object 'Everyone' from our side. The sentence was in Simple Present tense, so we used the rules of the Simple Present tense.
