Passive Voice Transformation:

The active voice sentence "They go to school everyday" can be transformed into the passive voice as follows:

Everyday, school is gone to by them.

Explanation of the Transformation:

1. Identifying the subject and object: In the given active voice sentence, "They" is the subject and "school" is the object.

2. Changing the positions: In the passive voice, the object becomes the subject and the subject becomes the object. Therefore, "school" becomes the subject and "they" becomes the object.

3. Using the appropriate passive verb form: The verb "go" is changed into "is gone to" in the passive voice. The preposition "by" is used to show the doer of the action, which is "them" in this case.

4. Adding the time expression: The time expression "everyday" is retained in the passive voice sentence.

Benefits of Using Passive Voice:

1. Emphasizes the object: In the passive voice, the object becomes the focus of the sentence, which can be useful in certain contexts.

2. Hides the doer of the action: In some situations, it may be desirable to hide the identity of the doer of the action, which can be accomplished through the use of passive voice.

3. Adds variety to writing: Using passive voice can add variety to writing and prevent it from becoming monotonous.

4. Creates a formal tone: Passive voice is often used in formal writing to create a more objective and detached tone.

Conclusion:

In summary, transforming an active voice sentence into passive voice requires identifying the subject and object, changing their positions, using the appropriate passive verb form, and adding a time expression if necessary. While passive voice has its benefits in certain contexts, it should be used judiciously and not overused as it can make writing less clear and direct.
