构、表过去某时正在进行的动作、
when/while句型
语法专项突破
考频分析
初三外研版中,过去进行时是动词时态的重要考点,考频占时态考点的15%左右,主要分布在核
心题型:单项选择(1-2题)、完形填空(1-2题)、语法填空(1题)、书面表达(场景化应用,体
现动作连贯性)。在when/while引导的时间状语从句题目中,过去进行时与一般过去时的区分及
was/were+doing结构的正确运用是解题关键。
考查内容
·动词分类应用:系动词、实义动词、情态动词、助动词的辨析与功能
。时态与语态:过去进行时(was/were+doing结构)的基本构成,表过去某时正在进行动作的语境判
断,when/while句型中时态搭配规则,主动语态与被动语态的转换
·非谓语动词:todo、doig、do的固定搭配与句法功能(作宾语、宾语补足语、定语等)
知识点一:过去进行时的结构与用法
1.基本结构(be动词+现在分词)
1.肯定句:主语+was/were+doing(动词现在分词)
例句:(I)I was reading a book at8p.m.last night.(主语为I,be动词用was)
(2)They were playing basketball when I arrived.(主语为They,be动词用were)
2.否定句:主语+was/were+not+doing
例句:She was not(wasn't)watching TV at that time.
2.核心用法(表过去特定时间正在进行的动作)

A版知识点全解
1.时间标志:at8o'clock yesterday evening(昨晚8点)、this time last Monday(上周一这个时候)等
具体过去时间点
例句:He was doing his homework at9p.m.yesterday..(强调昨晚9点正在进行的动作)
2.无明确时间标志时,通过上下文暗示过去某时刻正在进行
例句:The phone rang while she was cooking.(烹饪动作在电话响时正在进行)
3.when/while句型(过去进行时与一般过去时的连用)
1.when引导时间状语从句(主句用过去进行时,从句用一般过去时)
例句:I was walking home when it started to rain.(下雨时我正在走路,stat为短暂性动词用一般过去
时)
2.while引导时间状语从句(主从句均用过去进行时,表动作同时进行)
例句:While my mom was washing clothes,I was cleaning the room.(妈妈洗衣服和我打扫房间同时进
行)
知识点二:过去进行时的核心用法与句型
1.基本结构与含义
1.主动语态结构:主语+was/were+动词现在分词(doing)(主语为单数/第三人称单数时用was,复
数/第二人称时用were)
2.含义:表示过去某一特定时间点或时间段正在进行的动作,强调动作的’持续性”和”未完成性
2.时间标志词
1.具体时间点:at9o'clock last night(昨晚9点)、this time yesterday(昨天这个时候)、fiom8tol0
a.m.last Sunday(上周日上午8点到l0点)
2.时间状语从句:when+一般过去时句子(当…时,强调另一个动作突然发生)、while+过去进行
时句子(当…期间,强调两个动作同时进行)
3.核心句型(when/while用法)
1.whn引导时间状语从句(从句用一般过去时,主句用过去进行时〉
结构:主句(过去进行时)+when+从句(一般过去时)
例句:I was walking home when it started to rain.(我正步行回家,突然开始下雨了。)
2.while引导时间状语从句(主从句均用过去进行时,表”同时进行”)
结构:主句(过去进行时)+whil+从句(过去进行时)
例句:My brother was playing video games while I was doing homework.(我弟弟在玩游戏时,我正在
写作业。)

3.while也可单独引导时间状语(后接现在分词,省略主语和was/were)
例句:She fell asleep while reading a novel.(她读小说时睡着了。)
4.被动语态
1.结构:主语+was/were+being+动词过去分词(was/were体现”过去”,being体现”进行',过去分
词体现”被动”)
2.例句
(I)The classroom was being cleaned by students at4p.m.yesterday..(昨天下午4点,学生们正在打扫
教室。)
(2)A song was being sung by her while her mother was cooking.(她妈妈做饭时,她正在唱歌。)
5.常见错误提醒
1.误用一般过去时:当强调”过去某时正在做某事”时,不可用动词过去式,需用'was/were+doing”
错误:He watched TV at8p.m.last night.(仅表”昨晚8点看了电视”,未体现”正在看)
正确:He was watching TV at8p.m.last night.(昨晚8点他正在看电视。)
2.when与while的区别:when后可接短暂性动词(如start,ring),while后需接延续性动词(如read,
play)
错误:While the phone rang,I was taking a shower..
正确:When the phone rang,I was taking a shower.(电话铃响时,我正在洗澡。)
知识点三:过去进行时
1.基础结构
1.肯定句:主语+was/were+动词-ing形式
→例句:She was reading a book at8p.m.last night.
2.否定句:主语+was/were+not+动词-ing形式
→例句:They were not playing football when I called,
3.疑问句:Was/Were+主语+动词-ing形式?
→例句:Were you watching TV at9o'clock yesterday?
2.时间状语(中考必背)
1.at8p.m.last Friday(上周五晚上8点)
→例句:He was doing his homework at8p.m.last Friday.
2.this time yesterday(昨天这个时候)
→例句:We were having a class this time yesterday.

3.when the rain started(当雨开始下的时候)
→例句:I was walking home when the rain started.
3.when/while句型(中考核心)
1.whn引导时间状语从句(从句用一般过去时,主句用过去进行时)
→例句:I was cooking when the phone rang
2.while引导时间状语从句(主从句均用过去进行时,表示动作同时进行)
一→例句:While my mother was washing clothes,I was doing my homework.
3.while+动词-ing形式(省略主语和be动词)
→例句:She fell asleep while reading a novel..
考法精析
考法一:过去进行时基本结构及用法
核心:根据主语人称/数选择正确be动词(was/were),结合时间标志词判断是否使用过去进行时
真题1(语法填空):
They-(play)basketball when the teacher came.
答案:were playing
解析:由时间标志词"'when the teacher came'”(一般过去时从句)可知,主句动作在过去某时正在进
行,主语They为复数,be动词用were,后接play的现在分词playing。
真题2(单项选择):
My sisterTV at 8 p.m.last night.
A.watches B.watched C.was watching D.will watch
答案:C
解析:由时间标志词”at8pm.last night'”(过去具体时间点)可知,动作在过去某时正在进行,用
过去进行时,主语My sister为单数,be动词用was,watch的现在分词为watching。
考法二:过去进行时与时间状语匹配
核心:根据时间状语的类型(具体时间点/特续时间段)及引导词(when/while),判断是否使用过
去进行时并正确构建句子结构
真题1(语法填空):
My sister(listen)to music when I(get)home yesterday.
答案:was listening:got
解析:由时间标志词'whn”可知,主句表示”过去某时正在进行的动作,用过去进行时(主语单数
用was listening),从句表示”另一个动作突然发生”用一般过去时(get的过去式为got)。
真题2(单项选择):
Theybasketball from 3 p.m.to 5 p.m.last Saturday.
A.play B.played C.were playing D.are playing
初三下册外研版
【寒假专版】
A版知识点全解
答案:C
解析:由时间标志词'fom3p.m.to5p.m.last Saturday'(过去持续时间段)可知,动作在过去特定
时间段内持续进行,用过去进行时,主语复数用were playing。
考法三:过去进行时与when/while句型的综合运用
核心:结合时间标志词判断动作发生的背景,掌握when/while引导时间状语从句时主从句时态的搭
配规则(when后接一般过去时,while后接过去进行时或省略主语和be动词的现在分词形式)
真题1(单项选择):
ITV when my father came back last night.
A watch B watched C was watching D am watching
答案:C
解析:由时间标志词'when my father came back last night',可知,主句动作在从句动作发生时正在进
行,需用过去进行时,结构为”was/were+现在分词',主语为I,be动词用was,watch的现在分词
为watching。
真题2(语法填空):
While Tom(play)basketball on the playground,it suddenly began to rain.
答案:was playing
解析:while引导时间状语从句时,主从句动作同时进行,主句began”为一般过去时,从句需用过
去进行时,结构为"was/were+现在分词”,主语Tom为第三人称单数,be动词用was,play的现在
分词为playing。
解题小妙招
时态语态妙招
时态判断看标志,没有标志品语境:
过去进行两标志,具体时点段持续:
when主长从短暂,while两长同时行:
be动词随主语变,was配单were配复;
现在分词加ing,时态结构要牢记。
