（9大考点 · 基础+提升+拓展 三层训练 · 附详细解析）
★ 考点一：过去进行时（was/were + doing） ★
⚠ 易错速记：① 结构：was/were + V-ing；I/He/She/It → was doing；You/We/They → were doing；② 用法：过去某时刻正在进行的动作（At 8pm yesterday, I was reading.）；过去某段时间内持续动作（She was studying all morning.）；③ 常与when/while连用：When you called, I was taking a shower. / While I was cooking, he was setting the table.；④ 易错：was/were后接doing不是do（× was read → √ was reading）；when可接短暂/延续动词，while只接延续动词；⑤ 与一般过去时区别：过去进行时强调"正在进行/未完成"，一般过去时强调"已完成"
