(+by+动作的执行者)否定句：主语+wasn’t/weren’t

+动词过去分词

(+by+动作的执行者)定义：核心结构：be动词选择：时间标志词：

表示过去某个时间里，主语承受的动作或发生的被动状态（即动作的承受者作主语）

被动语态（一般过去时）was：用于主语是单数（I/he/she/it/单数名词/不可数名词）were：用于主语是复数（we/you/they/复数名词）yesterday（昨天）、lastweek（上周）、ago（……以前）、in2022（在2022年）、atthattime（在那时）、justnow（刚才）等be(was/were)+动词的过去分词

Activity2注意事项：

动词过去分词的构成：规则动词加-ed（如：cleaned,finished）；

不规则动词需牢记特殊形式（如：done,seen,written）；主动语态变被动语态时，主动句的宾语变被动句的主语，主动句的主语变被动句的by短语（可省略）；不及物动词（如：happen,occur,appear等）没有被动语态，因为它们不能承受动作。

Activity2被动语态（一般过去时）Activity3主动语态变被动语态
