He is well known to you.
Step 1: Understanding the Concept:
This question requires changing a sentence from active voice to passive voice. The active voice focuses on the doer of the action, while the passive voice focuses on the receiver of the action.
Step 2: Detailed Explanation:
1. Identify the subject (You), verb (know), and object (him) in the active sentence.
2. The object of the active sentence ('him') becomes the subject of the passive sentence ('He').
3. The verb 'know' is in the simple present tense. The passive form is 'is/am/are + past participle (V3)'. So, it becomes 'is known'.
4. The verb 'know' is followed by the preposition 'to', not 'by'.
5. The subject of the active sentence ('You') becomes the object of the preposition ('to you').
6. The adverb 'well' is placed before the verb phrase.
