八年级一般过去时知识点
过去进行时 概念：表示过去某时正在进行的动作或状态。基本结构：was\were 动词的现在分词（V·ing）常用的时间状语有 this morning,the whole morning,all day yesterday,from nine to ten yesterday(昨天从九点到十点),When\while 从句(从句常用过去式) ,while 从句(从句常用过去进行时）等。 例：
She was reading English this morning.今天早晨她正在读英语。
Tom was doing his homework from nine to ten yesterday. 昨天从九点到十点汤姆正在做家庭作业。
My parents were watching TV when I came home last night. 昨晚当我到家的时候我的父母正在看电视。
否定结构：wasn't \ weren't 单词的现在分词（V·ing），
因此，以上3句的否定句为：She wasn't reading English this morning.
Tom wasn't doing his homework from nine to ten yesterday.
My parents weren't watching TV when I came home last night.
一般疑问句：把was\were提到句子前面。
以上3句的一般疑问句为：
Was She reading English this morning?

Tom was doing his homework from nine to ten yesterday.
Yes,he was.\No,he wasn't.
Were your parents watching TV when you came home last night?
Yes,they were.\No,they weren't.
对比1：
My father was watching TV when I came home yesterday.昨天当我到家时，爸爸正在看电视。
主句（过去进行时） when引导的时间状语从句（一般过去时）
While my father was watching TV,I came home yesterday.
while引导的时间状语从句（过去进行时），主句（一般过去时）
对比2：My father was watching TV while my mother was cooking yesterday.
昨天当妈妈在做饭时，爸爸正在看电视。（主句和时间状语从句都使用了过去进行时，强调2个动作同时发生）
