教科版（五四学制）英语七下Unit4语法讲解及习题: 一般过去时&过去进行时、used to 本单元两大核心语法： 1. 一般过去时（Past simple）和过去进行时（Past continuous）（搭配when/while/as） 2. used to （过去常常、曾经） 一、语法知识点精讲 （一）一般过去时 & 过去进行时（when / while / as） 1. 一般过去时（Past simple） · 含义：描述过去已经完成、结束的短暂动作/单次事件 · 结构：主语 + 动词过去式 · 例句（贴合本单元“榜样、先驱、励志人物”话题）： He became a great pioneer when he was young. 他年轻时成为了一名伟大的先驱。 2. 过去进行时（Past continuous） · 含义：描述过去某一个时间点，正在持续进行、未完成的长动作 · 结构：主语 + was/were + 动词-ing · I/he/she/it → was + doing · we/you/they → were + doing · 例句： He was working hard to help others all his life. 他一生都在为帮助他人而不懈努力。 3. 三大连接词用法区别 连接词 时态搭配规则 含义 when 长动作（过去进行时）+ when + 短动作（一般过去时） 当……的时候（一个动作打断了另一个正在进行的动作） while 前后都用过去进行时，表示两个长动作同时持续发生 正当……期间 as 随着……；一边……一边……，多表示动作同步进行、伴随变化 伴随同步发生 · 例句 a. I was reading when he came. 他来的时候，我正在看书。（短动作打断长动作） b. My mom was cooking while I was doing my homework. 我做作业的时候，妈妈正在做饭。（两个长动作同时进行） c. As he was growing up, he learned to help more people. 随着他慢慢长大，他学会了帮助更多人。 4. 易错提醒 ❌ 错误：When I arrive, he slept. ✅ 正确：When I arrived, he was sleeping. （描述过去的事，从句短暂动作用一般过去时，主句持续背景用过去进行时） （二）used to 的用法 1. 核心含义 · used to + 动词原形：过去常常做某事，但是现在已经不做了 · 只用于描述过去，没有现在时和将来时 2. 句式结构 · 肯定句：主语 + used to + 动词原形 He used to live a very hard life. 他过去曾经过着非常艰苦的生活。 · 否定句：主语 + didn’t use to + 动词原形 He didn’t use to have much money. 他过去并没有很多钱。 · 一般疑问句：Did + 主语 + use to + 动词原形? Did you use to play sports every day? 你过去每天都运动吗？ 3. 易错避坑 ❌ 否定：He usedn’t to...（初中阶段不常用） ✅ 标准否定：He didn’t use to... ❌ 疑问句：Used he to...（初中阶段不常用） ✅ 标准疑问：Did he use to... ❌ 混淆：be used to（习惯于） 区分：used to do = 过去常常做；be used to doing = 习惯于做 二、专项练习题 （一）用动词正确形式填空（一般过去时/过去进行时） 1.
