英语人教版九年级全册主动语态变被动语态.docx 免费在线阅读

（1）知识目标：明白英语中的两大语态即：主动语态和被动语态。 （2）能力目标：掌握主动语态如何变成被动语态，提高解题能力，提高中考被动语态题目的答对率。 四、教学重点：主动语态各种时态的结构变成被动语态的方法。 五、教学难点：使役动词和感官动词的被动语态，以及如何分辩中文的句子应采用何种语态。 六、教学辅助： ppt 七、教学过程： Step 1:Lead in1.读句子,看看不同在哪里？ ①、We clean our classroom every day ②、 Our classroom is cleaned by us every day学生细心观察这两个句子，第一个句子为主动语态，第二句子为被动语态。 教师提问：被动语态的结构和标志？ 学生回答：be+p.p和by+sb. 2.教师与学生口头复习p.p.的构成。 使学生明白主动和被动语态的区别。从而得出主动语态变成被动语态的方法：即:、“主变宾、宾变主,谓语动词变被动” 注:主变宾即主语变为介词by宾语Step 2:小组讨论：主动语态变成被动语态学要几个步骤？ 学生自由发言，教师总结：把主动语态改为被动语态可按“一变 、二套、三注意” 来进行。 ①变－－－把主动语态的宾语改为被动语态的主语，把主动语态的主语改为被动语态的介词by的宾语。②套－－－根据原句的时态套用相应时态。 ③注意－－注意人称的变化而引起的主谓一致问题。 例：①Many people speak English. English is spoken by many people. ②He washed his shoes yesterday. His shoes were washed by him yesterday.Step 3:一些特殊情况的主动语态变成被动语态的方法总结。 1.一些使役动词let, have, make等或感官动词see、 hear、 watch、 notice等在主动语态中后面接的动词不定式不带to，但改为被动语态时，要补上to。如：The boss makes the workers work 18 hours a day. The workers are made to work 18 hours a day by the boss.I saw him enter the house. He was seen to enter the house by me.The teacher let them leave the classroom after class. They were let to leave the classroom by the teacher after class.We hear her sing in the room every day. She is heard to sing in the room every day.2.[注意]当使用see/hear/watch sb doing sth时，变为被动语态时，doing保持不变。如：eg. I saw him going into the shop.主动 He was seen going into the shop.被动 3.含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一般变间接宾语为主语时比较多。 eg. My uncle gave me a present on my birthday. I was given a present on my birthday. 如果把直接宾语指物改为主语，则在间接宾语指人前加适当的介词。 如上句还可以说：A present was given to me yesterday Step 4:教师提出：take place, happen, belong to无被动语态；商场开业（open）无须用被动语态。 Step 5:把下列主动句改为被动句 ①Lily writes many letters every day. 主动②They visited this farm last year.（主动）③We have learned 3000 English words so far.（主动）Step 6:布置作业:思考：被动语态如何变成主动语态？
