学 习 过 程
环节 学习流程及内容 二次备课
Step1 Step2 Step3 Step4 Read the learning objectives. Lead-in 任务一: （指向目标一；检测目标一） Ask and answer :Talk about who invented the tea and when. Presentation 任务二: （指向目标二；检测目标二） 1、Underline the passive voice sentences in grammar focus. 2、Analyze all the examples in Grammar Focus with the class. 英语动词有两种语态，即 （Active Voice）和 （Passive Voice）。当主语为动词的 时，谓语的形式为 语态；当主语为动作的 时，谓语要用 语态。 一、被动语态的构成 The classroom is cleaned by the students every day. 一般现在时被动语态： 主语 + ______________ + ________ The tea was invented by Shen Nong 5000 years ago. 一般过去时被动语态： 主语 + ______________ + ________ 二、一般过去时的被动语态句型结构 肯定句：Eg. This meal was made by Tom. 主语+was/were+过去分词（ + by…) 否定句: Eg. This meal was not made by Tom. 主语+ was/were+ not +过去分词 (+by…) 一般疑问句:Eg. Was this meal made by Tom Was/Were+主语+过去分词(+ by …) Eg. What was made by Tom 特殊疑问句：特殊疑问词+ was/were+主语+过去分词（+ by ...) 一般过去时的被动语态几种特殊情况： 含有短语的主动语态变被动语态 短语动词在变成被动语态时，不能去掉构成短语动词的介词或副词. They took good care of my child. My child was taken good care of by them. 感官动词和使役动词的被动语态 即feel , hear , listen , look , watch , see , notice ； have , make , let 这些词在主动句中，其后的动词不定式不加to，但变被动句时必须加to. I saw him play basketball last Sunday. He was seen to play basketball last Sunday. 3.接双宾的谓语动词主动变被动 Sandy gave me a book.(Sandy gave a book to me.) 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: I was given a book by Sandy. 如果把指“物”的直接宾语变为主语，则在间接语前加to或for The book was given to me by Sandy. 这样的词还有pass, lend, bring等. 4.不能用于被动语态的情况 ①系动get/turn/become/seem/look/sound/smell/taste/feel+adj.不能变成被动结构。 ②happen, take place, break out, belong to, cost，be worth doing, run out, come out, come true等作谓语时，不能用于被动语态。 Practice 4a Rewrite the sentences using the passive voice. 4b Make students understand the meaning of the words in 4b，then finish it.
