Show answer & explanation
Correct answer: A
Explanation
Correct Answer
The teacher checks the homework every Friday.
Explanation
To convert a sentence from passive voice to active voice, the object performing the action in the passive agent phrase ("by the teacher") shifts to become the grammatical subject of the active sentence. Meanwhile, the original subject ("The homework") shifts to the object position after the verb.
The original passive sentence uses the simple present tense form "is checked" to show a recurring habit or schedule. When moving this to the active voice, the simple present tense must be maintained. Since the new subject "The teacher" is singular, it pairs with the singular simple present verb form "checks". This results in the clear active construction: "The teacher checks the homework every Friday."
Incorrect Alternatives:
The option "The teacher has checked the homework every Friday" incorrectly alters the tense to the present perfect.
The option "The homework was being checked by the teacher every Friday" keeps the sentence in the passive voice and incorrectly changes the tense to the past continuous.
The option "The teacher was checking the homework every Friday" incorrectly alters the tense to the past continuous.
Key Points
Word: The teacher checks the homework every Friday.
Meaning: The structurally accurate active conversion that retains both the original simple present tense and the intended contextual meaning.
Grammatical Role: Active voice declarative clause (functions to clearly denote the subject executing the action).
