Subject be (not) past participle I am/was (not) supported You/We/They are/were (not) He/She/It is/was (not) Revision 23021 Mr Wu is talking about the school Environment Week. Read what he says below and pay attention to the use of the passive voice. Last year, many trees were planted at the school during the Environment Week. This year, other eco-friendly activities will be organized. A recycling event is going to be held at our school. You can donate old clothes and shoes. They’ll be sent to poor areas. I hope everyone will take an active part in at least one activity and also vote for the activity you want to see in the future. 新课讲授 Read and summarise 23021 We form the passive voice in the simple future tense like this. subject will (not) be/be (not)going to be past particle I will (not) be/am (not) going to be supported. You/We/They will (not) be/are (not) going to be He/She/It will (not) be/is (not) going to be 23021 一般将来时的被动语态 定义：表示将来某个时间里，动作被执行、承受的状态 核心用途：不强调“谁做”，只强调“被做” 语境标志：常搭配将来时间状语（next week, tomorrow等） 与前两种时态被动的区别：动作发生在“未来” 核心结构：两种常用形式，语义相近，用法有差异 Explanation 23021 核心结构一： will be + 动词过去分词(PP) 基本结构：主语 + will be + 动词过去分词 用法侧重：强调意愿、预测，或未明确计划的将来动作 变否定：will + not（可缩写为won't）+ be + 过去分词 变疑问：Will + 主语 + be + 过去分词？ 关键：will无人称变化，所有人称均可用 23021 肯定句：A recycling event will be held at our school. （一场回收活动将在我校举行） 否定句：A recycling event won't be held at our school. 疑问句：Will a recycling event be held at our school? 肯定回答：Yes, it will. 否定回答：No, it won't. 解析：will be + held（hold的过去分词），表预测 23021 核心结构二：be going to be + 动词过去分词(PP) 基本结构：主语 + be going to be + 动词过去分词 用法侧重：强调计划、安排好的将来被动动作 变否定：be + not + going to be + 过去分词 变疑问：Be + 主语 + going to be + 过去分词？ 关键：be动词随主语人称、数变化（am/is/are） 23021 肯定句：An environmental show is going to be held at the town hall.（一场环保展将在市政厅举行） 否定句：An environmental show is not going to be held... 疑问句：Is an environmental show going to be held... 肯定回答：Yes, it is. 否定回答：No, it isn't. 解析：is going to be + held，表提前安排好的活动 23021 重点辨析：will be vs be going to be 相同点：均表示一般将来时被动，语义基本一致 will be：无计划、表意愿/预测。e.g. He will be invited.（可能临时决定） be going to be：有计划、表安排。e.g. He is going to be invited.（已确定） 判断技巧：看是否有明确的计划、安排或准备。 两者可互换，语境不同，侧重点不同 23021 1. Some books will be sent to the village.（无明确计划，表意愿） 2. Some books are going to be sent to the village.（有计划，已安排） 3. A new park will be built here.（预测，不确定具体时间） 4. A new park is going to be built here next month.（计划好，有时间） 核心：是否有“提前安排”的暗示 23021 一般将来时的被动语态使用场景 场景1：强调动作的承受者，突出被作用的对象 e.g. Other eco-friendly activities will be organized this year.（强调活动） 场景2：动作执行者不明确、不重要，无需提及 e.g. Leaflets will be sent to all people in the town.（无需说谁送） 场景3：表示计划、安排好的将来被动动作 e.g. The show is going to be held this Friday evening.（已确定时间） 23021 关键注意点一：动词过去分词 被动语态的核心：无论哪种时态，均需用动词过去分词 规则动词：加-ed（如organize→organized, design→designed） 不规则动词：需牢记（如hold→held, send→sent, do→done） 易错点：混淆过去式和过去分词（如send→sent，不可写sended） 技巧：结合前单元所学，整理本单元高频不规则分词 23021 关键注意点二：句式转换细节 否定句：只变will或be动词，过去分词保持不变 错误：will be not organized → 正确：will not be organized 疑问句：将will或be动词提前，其他成分不变 错误：Will be a show held? → 正确：Will a show be held? 回答时：用will或be动词呼应，简洁明了 23021 关键注意点三：by+执行者的用法 by+动作执行者，用于明确“谁做的动作”，可省略 e.g. The posters will be designed by Sandy.（明确执行者Sandy） 执行者不明确时，直接省略by部分，避免冗余 e.g. The posters will be designed.（无需说谁设计） 注意：by后接人称代词时，用宾格（如by him, by us） 23021 核心口诀总结 一般将来被动态，两种结构要记牢 will be加过分，意愿预测用得到 be going to be加过分，计划安排错不了 否定not加will/be，疑问will/be提前到 过分形式要记准，by加执行者可省掉 23021 Practice We use the passive voice in the simple future tense when the action has not taken place yet.
