Решение:
- 1. The original sentence is in the active voice: "Fiona takes the dog for a walk every day."
- 2. The object ("the dog") becomes the subject in the passive voice.
- 3. The verb "takes" is in the simple present tense. In the passive voice, we use the present tense of "to be" (is/am/are) + the past participle of the main verb.
- 4. The past participle of "take" is "taken".
- 5. Since "the dog" is singular, we use "is".
- 6. The phrase "for a walk" and the adverbial phrase "every day" remain in the sentence.
- 7. The agent "by Fiona" can be added.
- 8. Therefore, the passive form is: "The dog is taken for a walk by Fiona every day." or "The dog is taken for a walk every day."
Ответ: The dog is taken for a walk (by Fiona) every day.
