Introduction
In English grammar, voice is used to describe the relationship between the subject and the verb in a sentence. There are two types of voices: active voice and passive voice. Active voice is when the subject performs the action stated by the verb, while passive voice is when the subject receives the action.

Conversion of active voice to passive voice with two verbs
When there are two verbs in an active sentence, the first verb is the main verb and the second verb is the auxiliary verb. The main verb is the action verb that describes what is happening in the sentence, while the auxiliary verb helps to form the tense of the sentence.

To convert an active sentence with two verbs to passive voice, follow these steps:

1. Identify the subject, main verb, and auxiliary verb in the active sentence.
2. Move the object of the active sentence to the beginning of the passive sentence.
3. Use the auxiliary verb "be" in the same tense as the main verb in the active sentence.
4. Add the past participle of the main verb after the "be" verb.
5. Use "by" before the subject of the active sentence to show who performed the action (optional).

Example
Active: She is writing a letter.

1. Subject: She; Main verb: writing; Auxiliary verb: is
2. Object: a letter
3. Passive: A letter is being written by her.
4. "Is" is in the present tense, so "be" should also be in the present tense.
5. "By her" is optional.

Conclusion
Converting active voice to passive voice with two verbs can be done by identifying the subject, main verb, and auxiliary verb, moving the object to the beginning of the sentence, using the appropriate tense of "be" and adding the past participle of the main verb. The use of "by" before the subject of the active sentence is optional.
