1. Many books are published every year.
Explanation: In the sentence, we are talking about books being published, which is an action done by someone or something (not specified in the sentence). When using the passive voice, we need to use the auxiliary verb "to be" in the appropriate tense (present simple in this case) + the past participle form of the main verb. Therefore, "published" is the past participle form of the verb "to publish."

2. I am invited to her birthday party.
Explanation: In this sentence, the subject "I" is the one receiving the action of being invited. Again, when using the passive voice, we need to use the auxiliary verb "to be" in the appropriate tense (present simple in this case) + the past participle form of the main verb. Therefore, "invited" is the past participle form of the verb "to invite."

3. The house is built too slow.
Explanation: In this sentence, the subject "the house" is the one undergoing the action of being built. Again, we use the passive voice by using the appropriate tense (present simple) of the auxiliary verb "to be" + the past participle form of the main verb. Therefore, "built" is the past participle form of the verb "to build."

4. The exercise is written every lesson.
Explanation: In this sentence, the subject "the exercise" is the one undergoing the action of being written. To form the passive voice, we use the appropriate tense (present simple) of the auxiliary verb "to be" + the past participle form of the main verb. Therefore, "written" is the past participle form of the verb "to write."

5. Little children are loved by everyone.
Explanation: In this sentence, the subject "little children" are the ones receiving the action of being loved. When using the passive voice, we use the appropriate tense (present simple) of the auxiliary verb "to be" + the past participle form of the main verb. Therefore, "loved" is the past participle form of the verb "to love."

6. The new restaurant is visited by schoolchildren.
Explanation: In this sentence, the subject "the new restaurant" is the one receiving the action of being visited. To form the passive voice, we use the appropriate tense (present simple) of the auxiliary verb "to be" + the past participle form of the main verb. Therefore, "visited" is the past participle form of the verb "to visit."
