Day10.一般过去时：高频不规则动词过去式归类参考答案与详解
第一部分解析
1.bought |【解析】buy 的过去式，属于 ABB 型（buy-bought-bought）。
2.went |【解析】go 的过去式，ABC 变异型，标志词 just now。
3.did; see |【解析】还原陷阱！ 疑问句借用 did 后，see 必须用原形。
4.had |【解析】have 的过去式。
5.read |【解析】拼写陷阱！ AAA 型，read 的过去式拼写不变，但读音变为 /red/。
第二部分解析
6.cost |【解析】双重陷阱。 首先 AAA 型 cost 拼写不变；其次 did 后动词还原。
7.ate; drank |【解析】eat-ate; drink-drank。注意 i 变 a 的分类规律。
8.told; gave |【解析】tell-told; give-gave。动作接连发生，时态一致。
9.find; searched |【解析】第一空 did 后还原；第二空 search 是规则动词加 ed。
10.taught |【解析】拼写坑！ teach-taught。注意不要写成 thought（想）。
11.thought |【解析】“我原以为”，说明“以为”这个动作发生在过去。
12.left; shut |【解析】leave-left；shut 是 AAA 型，过去式不变。
第三部分解析
13.cut |【解析】AAA 型。 cut 的过去式还是 cut，且 who 引导的问句没用 did 时直接用过去式。
14.fell; hurt |【解析】对比考点。 fall 变 fell；hurt 虽是过去动作，但位于 didn't 后需还原，且 hurt 本身也
是 AAA 型。
15.rose; set |【解析】rise-rose；set 是 AAA 型（set-set-set）。
16.spent; doing |【解析】spend-spent；注意 spend time (in) doing 结构。
17.put |【解析】AAA 型。 put 过去式不变。
18.kept |【解析】keep-kept。语境提示昨晚发生的持续动作。30 天早背晚练——初中英语语法强基训练计划
Day 10：一般过去时：高频不规则动词过去式归类
一、时态判定：寻找“过去”的坐标
一般过去时表示过去某个时间发生的动作或存在的状态。
1.时间状语（信号词）： yesterday, last night/week, ... ago (如 two days ago), in 2020 (过去的年份), just now (刚才)。
2.语境暗示： 看到 used to, I thought...（我原以为）或上下文已经设定了过去背景。
二、动词过去式的规则变化（快速复习）
一般加 -ed (work→worked)
以 e 结尾加 -d (live→lived)
辅音+y 结尾，变 y 为 i 加 -ed (study→studied)
重读闭音节（辅元辅），双写末尾字母加 -ed (stop→stopped, plan→planned)
三、高频不规则动词：逻辑分类记忆（核心干货）
不要死记硬背！按发音和构词规律分类，记忆效率提升 3 倍：
A. “三位一体”型（AAA 型：原形-过去式-过去分词全同）
口诀： 设(set)置放(put)下让(let)它切(cut)，受伤(hurt)读(read)书花钱(cost)打(hit)。
注：read 过去式读音变为 /red/。
B. “中间变元音”型（ABB 型：过去式与过去分词相同）
i → u： dig → dug, stick → stuck
ee → e： meet → met, keep → kept, sleep → slept, feel → felt
ay → aid： say → said, pay → paid
买卖带来教与想（aught/ought）： buy → bought, sell → sold, bring → brought, teach → taught, think → thought
C. “骑马捉鱼”型（i → a：i 变 a，变出过去式）
i → a： sit → sat, drink → drank, sing → sang, swim → swam, begin → began
D. “变化无常”型（容易混淆的明星词）
o → e： know → knew, throw → threw, grow → grew
经典必考： go → went, do → did, eat → ate, give → gave, see → saw, come → came, run → ran
四、句型转换的“陷阱”：助动词 did
否定句： 主语 + didn't + 动词原形。
(×) He didn't went. → (√) He didn't go.
疑问句： Did + 主语 + 动词原形
(×) Did you saw him → (√) Did you see him
五、避坑指南
1.拼写陷阱：passed vs past
passed 是动词 pass 的过去式；past 是介词或名词。
例：He passed the exam. / He walked past me.
2.动作连续性
当描述过去连续发生的几个动作时，所有动词必须全部使用过去式（即时态一致原则）。
例：He stood up, put on his coat and left.
3.习惯性动作
used to do sth. 表示“过去常常做某事（现在不做了）”，本身就是过去时。
例：I used to play piano.
