The active-passive voice is used to change the focus of a sentence. The active voice emphasizes the subject performing the action, while the passive voice emphasizes the action being done to the subject. Writers may choose to use the passive voice to shift the focus onto the recipient of the action or to make the sentence more formal or impersonal. Additionally, the passive voice can be used to avoid placing blame or responsibility on a specific individual. **

The passive voice is used when the focus is on the action being done rather than the doer of the action. It is often used when the doer is unknown, unimportant, or when it is obvious. The active voice, on the other hand, is used when the focus is on the doer of the action. It is more direct and clear, making the sentence more engaging and easier to understand. **

The preterite of the active voice is transformed into the passive voice by changing the conjugation of the verb and adding the appropriate form of the verb "ser" followed by the past participle of the main verb. For example, the active voice sentence "Ellos compraron el libro" (They bought the book) can be transformed into the passive voice as "El libro fue comprado por ellos" (The book was bought by them). In this transformation, the conjugated verb "compraron" is changed to "fue comprado" and the subject "ellos" becomes the agent introduced by the preposition "por." **

To convert the passive voice to active voice, you need to identify the subject performing the action and make it the focus of the sentence. Then, you should place the subject at the beginning of the sentence and rephrase the sentence to show the subject performing the action. For example, "The book was read by me" can be changed to "I read the book." Converting active voice to passive voice involves identifying the subject performing the action and making it the object of the sentence. Then, you should place the object at the beginning of the sentence and rephrase the sentence to show the object being acted upon. For example, "She wrote the report" can be changed to "The report was written by her." **

To convert the simple past tense of the active voice into the passive voice, the object of the active sentence becomes the subject of the passive sentence. The verb in the active sentence is changed to the past participle form and the subject of the active sentence is introduced with the preposition "by" or omitted entirely. For example, in the active sentence "The chef cooked the meal," the passive form would be "The meal was cooked by the chef." **

Of course! Active voice is when the subject of the sentence performs the action, while passive voice is when the subject receives the action. For example, in active voice, "The cat chased the mouse," the subject (cat) is performing the action (chased). In passive voice, the sentence would be "The mouse was chased by the cat," where the subject (mouse) is receiving the action (chased). Let me know if you need more examples or assistance with active and passive voice! **

To determine if a sentence is in the passive or active voice, look for the subject performing the action. In the active voice, the subject performs the action, while in the passive voice, the subject receives the action. For example, "The cat chased the mouse" is in the active voice because the subject "cat" is performing the action "chased." On the other hand, "The mouse was chased by the cat" is in the passive voice because the subject "mouse" is receiving the action "chased." **

To write a sentence in the active voice, the subject of the sentence performs the action. For example, instead of saying "The ball was kicked by the boy," you would say "The boy kicked the ball." This makes the sentence clearer and more direct, as the focus is on the person or thing performing the action. **
