Answer:
In the passive voice, the sentences become the following:
1. Outdoor games are enjoyed by the children.
2. The crops were destroyed by the floods.
Step-by-step explanation:
The original sentences are in the active voice, which means they emphasize the performer of the action. To transform them into passive sentences, we need to emphasize the receiver of the action. Thus, what is the object in the active voice becomes the subject in the passive voice.
1. outdoor games
2. the crops
Now we identify the verb tense. We must add the auxiliary "be" in the same tense as the original sentence. The main verb is used in its past participle form.
1. enjoy (present) -> are enjoyed
2. destroyed (past) -> were destroyed
Finally, the subject of the active sentence becomes the agent of the passive, preceded by the preposition "by":
1. by the children
2. by the floods
Thus, we have:
1. Outdoor games are enjoyed by the children.
2. The crops were destroyed by the floods.
