This document discusses the future passive voice in English grammar. It explains that in passive sentences, the thing receiving the action is the subject and the thing doing the action can be optionally included. The future passive is formed using "will/shall + be + past participle" and optionally "by + the thing doing the action". Examples are provided of changing active sentences into the passive voice in the future tense, including affirmative, negative, and interrogative sentences. Bibliography sources on the future passive voice in English are also listed.
