period of time,using a large number of example sentences and practice questions to improve their proficiency and ability to switch between the two voices.This practice method helps students consolidate their knowledge and improve the accuracy of language use.Concentrated practiceBlocked practiceComprehensive exercisesChapter exercisesComprehensive exercises05Analysis of Common Errors in Active Voice and Passive VoiceSummary:In the conversion of active voice and passive voice,the order of subject and object is often reversed,leading to sentence structure confusion.In active voice,the subject usually appears before the object,but in passive voice,the object becomes the subject,and the original subject is placed at the end of the sentence or expressed in other ways.Therefore,during the conversion process,special attention needs to be paid to maintaining the correct word order and avoiding the inversion of subject object.Inversion of subject and objectSummaryDetailed

active and passive voices It is helpful to compare examples of senses using the active and passive voices to see the differences and appropriate the contexts in which each voice is appropriate As language learners progress in their English studies,they will enroll more complex uses of the passive voice,so as in complex senses and long texts Continuing practice and exposure to authentic materials will help develop expertise in this areaPractice makes perfectCompare and contrastFuture learningLearning suggestions and perspectives感谢您的观看THANKS
