Definition: The active voice is that by which the action indicated by the main verb of a sentence is performed by the subject of the same. In Russian, just like in English, most sentences are constructed in active voice.
The structure is the same as in English: Subject + Verb + Complement
Examples:
In Russian, for write a Passive sentence you can add the suffix ся(ца) after the verb if the verb finished in consonant but if the verb finished in vowel you must add the suffix сь; but these suffixes not ever are used because the verb must be a reflexive verbs. Subject + Verb + (ся or сь) + Complement
Examples:
Salsa is danced by my
Сальса танцуется моим.
Salʹsa tantsuet·sya moim.
The book is written by you.
Книга написана вами.
