初二英语 · 语法复习
明明记住了went，为什么写成didn’t went还是错？一般过去时的关键，不只是背过去式，还要弄清一句话里由谁承担过去时标记。
适用：初二英语基础复习｜建议用时：25分钟
01 / 学习目标与规则
一般过去时描述过去发生的动作或过去存在的状态。常见时间表达有yesterday、last week、two days ago，但判断时也要看上下文。
含实义动词的肯定句使用过去式：She visited the museum yesterday. 否定句使用did not + 动词原形：She did not visit the museum yesterday. 一般疑问句是Did + 主语 + 动词原形：Did she visit the museum yesterday?
be动词单独处理：I/he/she/it常用was，you/we/they常用were；否定式wasn't/weren't；疑问句把was/were放到主语前。不要写Did you were tired?
规则变化如work→worked、live→lived、study→studied、stop→stopped。不规则形式需要逐项掌握，如go→went、see→saw、buy→bought、have→had、do→did。
规则动词双写不能只凭最后一个字母判断，stop属于相应的重读闭音节情形。
02 / 例题讲解
She ___ (go) to the library last Saturday. 答案went。时间为上周六，肯定句中的go变为过去式。
改为否定句：She didn't go to the library last Saturday. did已经承担过去时标记，因此后面恢复go，不能写didn't went。
They were busy yesterday. 改为疑问句：Were they busy yesterday? 本句谓语是be，不借助did。
03 / 自测：先完成，再看答案
1. We ___ (watch) a film last night.
2. Tom ___ (study) English yesterday afternoon.
3. I ___ (not buy) anything at the shop yesterday.
4. ___ you ___ (see) Lucy at school yesterday?
5. My parents ___ (be) at home last Sunday.
6. 改错：Did he finished his homework last night?
7. 把She was tired yesterday.改为否定句和一般疑问句。
8. 用45—60个英语单词描述上个周末，至少包含三个过去式，并说明一件事情的感受。
04 / 参考答案与解析
先完成练习，再向下核对。比起只看对错，更值得记录的是：自己在哪一步想错了。
1. watched：规则动词加-ed。
2. studied：辅音字母+y结尾，变y为i加-ed。
3. didn't buy：否定结构后接原形。
4. Did；see：助动词在前，实义动词用原形。
5. were：主语为复数，描述过去状态。
6. finished改为finish。不要重复标记过去时。
7. She wasn't tired yesterday. / Was she tired yesterday?
8. 参考范文（49词）：Last Saturday, I visited my grandparents with my parents. We cooked lunch together and talked about our week. In the afternoon, I helped my grandfather clean the garden. On Sunday, I finished my homework and read a short story. I felt tired but happy because I spent time meaningfully.
05 / 自查清单
圈出作文里的动词，逐一检查：过去动作是否用过去式？did后面是否用原形？was/were是否与主语搭配？不要仅检查时间词，也要检查每一句的谓语。若第3、4、6题有错，用同一个动词连续写一组肯定、否定、疑问句。
06 / 学完这一篇，留下一个方法
任选go、study、watch中的一个动词，连续写出肯定句、否定句和一般疑问句。写完只查一件事：did后面是不是原形？
