(2) Tom lets his little sister water flowers everyday.→ They are made to work ten hours a day.→ His little sister is let to water flowers everyday by Tom.5. 如果主句中有两个宾语(间接宾语和直接宾语),可以将其中任何一个变成被动句的主语。常用双宾语的动词:show/give/offer/send /bring/lend/teach/buy例如:The teacher gives the pupils some advice.直接宾语间接宾语→The pupils are given some advice by the teacher.→Some advice is given to the pupils by the teacher.宾变主,主变宾,by短语后面跟。谓语动词变被动,be后“过分”来使用。被动语态的基本用法1. 当不知道或没必要说明动作的执行者时,可以不用by短语。Most of his money is spent on the car.2. 当动作的执行者是谈话的中心时,可以用by短语。Chinese is learned by more and more foreigners.3. 强调动作的承受者时。A lot of trees are planted every spring.一、把下列句子变为含被动语态的句子。1.Mr. Li corrects the students’ homework every morning.The students’ homework is corrected by Mr. Li every morning.2.People play basketball all over the world.Basketball is played by people all over the world.主语主语谓语宾语谓语宾语练一练 3.
