概念：
在一个词的词根前面或后面加上某个词缀来产生新词，这种构词法称为派生法或词缀法。加在前面的词缀叫前缀，加在后面的词缀叫后缀。一般情况下，前缀往往改变词根的词义，不改变词根的词性；而后缀往往改变词根的词性，有些也涉及意义的变化。

过去进行时:表示过去某一具体时刻或某段时间内正在发生、持续进行的动作。
本质：“过去 + 正在进行”，强调动作在过去的 “时间节点 / 时间段” 中处于 “未完成、持续进行” 的状态。
例：She was watching TV at 8 o'clock last night.（昨晚 8 点，她正在看电视。-强调 “8 点这个时刻” 动作正在进行）
The past continuous tense
句式 例句
肯定句 He was reading a novel.（他正在读小说。）
否定句 They were not playing football.（他们没在踢足球。）
一般疑问句 Were you listening to music （你当时在听音乐吗？）
特殊疑问句 What was she doing at that moment （那一刻她在做什么？）

The past continuous tense
构成规则: “be 动词的过去式（was/were）+ 动词 - ing 形式” 构成
tips：
主语为第一 / 三人称单数（I, he, she, it）时，用 “was”；
主语为第二人称 / 复数（you, we, they）时，用 “were”。
常见时间状语
过去进行时的识别依赖 “过去时间标志”，以下为高频时间状语：
具体时刻：
at 8 o'clock last night, at that moment, at this time yesterday
时间段：
from 3 to 5 p.m. last Sunday, during the meeting, all afternoon
从句引导词：
when当…… 时，常用一般过去时;while在…… 期间，常用过去进行时

The past continuous tense
维度 过去进行时 （Past Continuous） 一般过去时
（Simple Past）
核心含义 强调 “动作正在进行的过程”（未完成） 强调 “动作完成的事实 / 结果”（已结束）
时间关联 与 “具体时刻 / 持续时段” 绑定 与 “笼统过去时间” 绑定（如 yesterday, last year）
例句对比 He was writing a letter at 7 p.m.（7 点时正在写信 —— 强调过程） He wrote a letter at 7 p.m.（7 点写了一封信 —— 强调 “写了” 这个结果）
