4. 区分过去进行时与一般过去时的差异
学习目标
时态核心定义
过去进行时,表示过去某一时刻正在发生的动作。
也可表示过去某段时间内持续进行的动作。
侧重强调:过去动作的“持续性、正在进行”状态。
常用来描述过去突发意外的背景动作。
基本句型结构(肯定句)
核心公式:主语 + was/were + 现在分词(doing)
单数主语用 was,复数主语用 were
例句:I was reading books at 8 last night.
译文:昨晚八点我正在看书。
基本句型结构(否定句)
公式:主语 + was/were + not + doing
缩写:wasn’t / weren’t + 现在分词
例句:They weren’t playing football then.
译文:那时他们没有在踢足球。
基本句型结构(一般疑问句)
公式:Was/Were + 主语 + doing + 其他?
肯定回答:Yes, 主语+was/were.
否定回答:No, 主语+wasn’t/weren’t.
例句:Was she sleeping at that time?
基本句型结构(特殊疑问句)
公式:特殊疑问词 + Was/Were + 主语 + doing?
用于询问过去正在做的具体事情
例句:What were you doing yesterday evening?
译文:昨晚你正在做什么?
动词ing变化规则
1. 一般动词直接加ing:read→reading
2. 以不发音e结尾,去e加ing:write→writing
3. 重读闭音节,双写尾字母加ing:run→running
4. ie结尾变y加ing:lie→lying
核心时间标志词(必考)
1. at that time / at that moment 在那时
2. at + 具体时间 + yesterday 过去具体时刻
3. from 7 to 9 last night 过去时间段
4. while / when 引导的过去时间状语
when与while用法精讲
when:可接瞬间动词、延续动词,译为“当……时”
while:只接延续动词,多用于过去进行时
经典句式:长动作(进行时)+ when + 短动作
长动作持续中,突发短动作发生
when例句
I was walking home when it began to rain.
译文:我正走回家,这时突然下雨了。
was walking 长动作,began 突发短动作
贴合单元意外事件的写作场景
while例句
My mum was cooking while I was doing homework.
译文:我做作业的时候,妈妈正在做饭。
while连接两个同时进行的过去长动作
前后均使用过去进行时
时态辨析(重点难点)
过去进行时:强调正在进行、持续状态
一般过去时:强调动作已经完成
例:I read a book last night.(读完了)
例:I was reading last night.(一直在读)
高频易错点1
瞬间动词无进行时态
die/arrive/start/begin 不能用于进行时
错误:He was arriving at 8 yesterday.
正确:He arrived at 8 yesterday.

单复数主语搭配出错
单数/不可数名词/人称I/he/she/it → was
