Explanations and examples of active and passive voice are here.
To change the sentence "I have been registering scores like that" into passive voice, you need to follow a few steps:
Step 1: Identify the subject, verb, and object of the sentence.
- Subject: I
- Verb: have been registering
- Object: scores like that
Step 2: Move the object to the beginning of the sentence (as the new subject).
- Object: Scores like that
Step 3: Add the verb "to be" in a suitable tense (based on the original verb tense). Since the original verb is "have been registering," we need to use the appropriate form of "to be," which is "have been" in present perfect continuous tense.
- Object becomes subject: Scores like that
- Verb "to be" in present perfect continuous tense: have been
Step 4: Change the original main verb (registering) to its past participle (registered).
- Original verb: registering
- Past participle: registered
Step 5: Add the preposition "by" before the original subject.
- Original subject: I
- Preposition "by": by
Putting it all together, the passive voice sentence becomes: "Scores like that have been registered by me."
Remember that in passive voice constructions, the doer of the action (I, in this case) becomes less important and often omitted.
