The document discusses the use of passive voice in translation between English and Spanish. It notes that while some English passive voice sentences can be directly translated into Spanish passive voice, not all can. Specifically, it provides the example of how "Congress was sent a new law" would be translated into Spanish using the active rather than passive voice. The document also notes that some Spanish verbs are simply not used in the passive form. It concludes by stating that passive voice is most commonly used in instructions, orders and signs.
