Johns dog will be taken back by him.否定式： will/shall + not + be + 过去分词Eg. The work wont be finished until next week.一般疑问式：will/shall+主语+be+过去分词Will the house be painted again next month?特殊疑问式：特殊疑问词+shall/will+主语+be+过去分词+其他Where will the cinema be built?Step4：认真观察下列句子，总结将来时的被动语态的形式(1) 主语+谓语+宾语，例如：主动:Well build a new house next year. 被动:A new house will be built(by us) next year.(2) 主语+谓语+间接宾语+直接宾语(习惯上把间接宾语变为被动语态的主语)主动: My mother will give me a shirt.被动: I will be given a shirt (by my mother).主动: My mother will give me a shirt.被动: A new shirt will be given to me (by my mother).(3)主语+谓语+宾语+宾补。主动: Well ask him to help you tomorrow.被动: He will be asked to help you (by us). Step5:英语中“主动形式”表“被动意义”的情况：(1). A. sth need/want/require/+doing 主动表被动 表示“某物需要/该被” B. sb/sth be worth doing 主动表被动 表示“ 某物值得”The bike needs requiring.The book is worth reading.(2) 表示主语的某种属性的词：sell， wash，write，read，act，cut，draw，drive， wash，clean，wear等，这些词通常与副词连用，主动表被动。Eg. The books sell well. 这些很书畅销。(3) 系动词look，feel，sound，smell，taste，seem，appear，go，prove，turn等形容词/名词。Eg. Ice feels cold. His idea sounds good. “日清过关”三级达标训练题（共24分） 基础题：用所给动词的适当形式填空 1.
