Final answer:
To convert the sentence 'Amy writes the report' to passive voice, use the present tense form of 'to be,' resulting in the sentence 'The report is written by Amy.'
Step-by-step explanation:
To change an active verb to passive, you must add the correct form of the verb to be appropriate for the tense of the sentence. In the example you provided, 'Amy writes the report,' we must use the present tense form of the verb to be which is 'is', and then add the past participle of the verb 'write,' which is 'written.'
The correct passive construction of your sentence would be: 'The report is written by Amy.'
