Unit 1 Our world语法(现在进行时的被动语态)讲解导学案-2026-2027学年沪教版英语必修第一册暑假衔接

Unit1 Our world语法讲解与练习 现在进行时的被动语态精讲 一、定义 现在进行时被动语态，表示此时此刻正在被做/现阶段一段时期持续被开展的动作，突出动作正在进行，主语是动作承受者。 区分两组易混时态： 1.一般现在时被动 am/is/are done：常态、客观规定、经常性被做 2.现在进行时被动 am/is/are being done：此刻/现阶段正在被实施 二、固定核心结构 基础公式 主语 + am /is/are + being + 动词过去分词 (done) 拆解三部分缺一不可： 1.am/is/are：匹配主语单复数、人称，体现现在时 2.being：标志 “进行”，绝对不能省略（最高频易错点） 3.done：被动含义，不规则动词特殊变形需熟记 四种句式（带单元例句） *肯定句：主语 + am/is/are + being done More trees are being planted around the globe. 全球各地正在种植更多树木。 *否定句：主语 + am/is/are + not + being done The polluted oceans are not being cleaned fast enough. 被污染的海洋没有得到快速清理。 *一般疑问句：Am/Is/Are +主语+ being done? Is the plastic waste being recycled in this community? 这个社区的塑料垃圾正在被回收吗？ *特殊疑问句：疑问词 + am/is/are +主语+ being done? What new green rules are being carried out worldwide? 全球正在推行哪些新环保法规？ 三、两大核心用法 用法 1：此时此刻正在发生（即时场景） 标志词：now, right now, at the moment, Look!, Listen! 例句：Look! Endangered animals are being protected in this reserve. 看！这片保护区里的濒危动物正在受到保护。 用法 2：现阶段持续进行（此刻不一定在现场操作） 标志词：these days, currently, at present, nowadays 例句：New renewable energy stations are being built these years. 近些年新能源电站一直在修建。 拓展特殊用法（高一拔高考点） 与 always/constantly连用，带强烈感情色彩（批评/惋惜） 例句：Natural resources are always being wasted by some factories. 总有工厂在不断浪费自然资源（表批评） 四、主谓一致规则 1.单数可数名词/不可数名词 → is being done The river is being purified. 这条河流正在被净化。 2.复数名词 → are being done Rivers are being purified. 多条河流正在被净化。 3.I 搭配 am being done I am being asked to join the environmental activity. 我正被邀请参加环保活动。 五、高频易错点 1.漏写 being ❌ The park is built. ✅ The park is being built. 2.主谓不一致：复数主语误用is，单数误用are 3.短暂瞬间动词无进行被动：die, finish, stop 不用于此结构 4.区分主动进行与被动进行： People are saving water.（主动） Water is being saved.（被动） 【配套专项练习题】 第一大题 用所给词正确形式填空 1.At present, thousands of new trees ________ (plant) along the coast. 2.Look!
