Section Ⅳ　Discovering Useful Structures 现在进行时的被动语态 教材示例 1．(教材原句)What is being done to help them? 2．(教材原句)I know that they're being hunted and their habitat is getting smaller. 3．(教材原句)What measures are being taken to help them? 4．(教材原句)Much is being done to protect wildlife，but if we really want to save the planet，we must change our way of life. 我的发现 以上句子中的黑体部分为现在进行时的被动语态，其构成形式为be (am/is/are)＋being＋动词的过去分词。 一、含义 现在进行时的被动语态表示现在或现阶段正在进行或发生的被动动作，强调主语是动作的承受者。 二、结构 1．肯定式：主语＋am/is/are ＋being done... Some trees are being cut down in the park. 公园里的一些树木正在被砍伐。 2．否定式：主语＋am/is/are＋ not being done... It is reported that the water in the lake is not being protected now. 据报道，这个湖里的水现在没有得到保护。 学生用书↓第49页 3.一般疑问式：Am/Is/Are (not)＋主语＋being done...?

(把①句改为一般疑问句) ④Where is a modern school being built?
