Unit 4 Back in time

专题02 语法提升·易错题专项训练

一般过去时的特殊疑问句（what/why/how/when 引导）

询问过去发生的动作、状态、时间、方式、原因等，是一般过去时的核心交际句型，核心分为两类结构，答语需严格使用一般过去时对应作答。

1. 对动作提问：特殊疑问词 + did + 主语 + 动词原形 + 其他？（适配what/where/how/when等疑问词）

核心规则：助动词did无单复数变化，后必须接动词原形，不可接过去式

2. 对状态提问：特殊疑问词 + was/were + 主语 + 其他？（适配what/why/how等疑问词）

核心规则：主语为单数/不可数名词用was，复数主语用were，无需加助动词did

第一步：锁定疑问词——根据答语核心信息，匹配对应的疑问词（问动作/事物用what，问时间用when，问方式用how，问原因用why）

第二步：判断句型结构——对动作提问加助动词did，对状态提问用was/were，不可混用

第三步：规范动词形式——did后必须接动词原形，答语中实义动词用过去式，be动词用was/were
