18、 nice smell so he tasted the brown water. It was quite delicious and one of the worlds favorite drink was invented.Tell something about Lu Yu and his Cha Jing. Grammar Focus. . Grammar一般过去时态的被动语态的构成 英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。We cleaned the classroom yesterday. 我们昨天打扫了教室。（主动

19、语态，主语we是clean这一动作的执行者）The classroom was cleaned yesterday. 教室昨天被打扫。（被动语态，主语the classroom是clean这一动作的承受者）一、一般过去时被动语态一般过去时被动语态的结构为“主语+ was /were +及物动词的过去分词 （+by+动作的执行者）.”。Trees were planted last spring.去年春天种了树。二、被动语态的用法：1. 不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。 e.g. English is spoken all over the world. 全世界都在说英语

20、。2. 需要突出或强调动作的承受者。 e.g. This dictionary is used by most students. 这本字典是大多数学生在用的。三、主动语态变被动语态应注意的问题1. 有些短语动词相当于及物动词，变为被动句时介词或副词不能去掉。2. 含有双宾语的主动句变为被动句时，通常把指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指物”的直接宾语变为主语，则在间接宾语前加to或for。 3. 主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式，变为被动语态时应加上不定式符号to。4. 系动词、

21、不及物动词或某些短语动词（happen, take place, come true, fall asleep）没有被动语态。. PracticeWork on 4a:1. Tell Ss to read the sentences in 4a and rewrite the sentences using the passive voice. 2. 做题方法点拨示例： 点拨：原句为一般过去时态，原句的谓语动词为sold，宾语为the fridge；改为被动语态时，应将the fridge作主语，谓语动词用was sold的形式。 点拨：分析原句的句子结构可知，stole是谓语动词，my ca

22、mera是句子的宾语；改为被动语态句时，应将my camera作句子主语，谓语动词用was stolen的形式。3. 最后，教师与同学们一起校对答案，并对学生们有疑问的地方进行解释，或做出合理的分析点拨。 Where were these photos taken? We were advised not to go out alone.
