Here's why:
* Active voice: In an active sentence, the subject performs the action. The sentence structure is "Subject + Verb + Object".
* Two-part verbs: These are verbs that are made up of two words, usually an auxiliary verb (like "have", "be", "will") and a main verb (like "eaten", "been", "go").
Here are some examples:
Active Sentence with a Two-Part Verb:
* *She has eaten the cake.* (Subject: She; Verb: has eaten; Object: the cake)
Active Sentence without a Two-Part Verb:
* *The dog barked at the mailman.* (Subject: The dog; Verb: barked; Object: the mailman)
The presence of a two-part verb is determined by the tense and aspect of the verb, not by whether the sentence is active or passive.
