期末复习学案七年级下册英语 Unit 8 Once upon a Time
一、单元逻辑
本单元以“故事”为载体,核心任务是用一般过去时讲好一个故事。复习不再是背单词,而是掌握“故事链”:开端(Once upon a time)→ 发展(动词过去式串联)→ 高潮(冲突/对话)→ 结局(寓意)。
单元核心图谱
故事名称
核心语法载体
必背寓意(英文)
The Lion and the Mouse
一般过去时(并列动作)
Kindness is never wasted.
The Emperor's New Clothes
否定疑问句、感叹句
Honesty is the best policy.
The Ugly Duckling
情感变化描写
Don't judge by appearance.
The Fisherman and the Genie
条件状语从句(If...)
Wisdom beats power.
二、知识梳理
板块 1:核心词汇“深挖”(拒绝死记硬背)
一级必会(会写+会用)
词汇
深度拆解与易错警示
bite – bit
动词,“咬”。⚠️易错:过去式是不规则变化 bit,不是 bited。短语:bite through(咬穿)。
catch – caught
动词,“抓住”。⚠️易错:过去式 caught 读音 /kɔːt/,常考拼写。
lie
动词,本单元指“撒谎”。⚠️大坑:lie 有三个意思,七下只考“撒谎”(lied-lied)。八上会考“躺;位于”(lay-lain)。口诀:规则的“撒谎”(lied),不规则的“躺”(lay)。
decide
动词,“决定”。固定搭配:decide to do sth.(决定做某事),否定:decide not to do。
afraid
形容词,“害怕的”。固定搭配:be afraid to do(不敢做);be afraid of doing(担心发生某种后果)。
fisherman
名词,“渔夫”。⚠️易错:复数是 fishermen(man → men),不是 fishermans。
二级认读(见词知义)
• net (网), neighbour (邻居), silly (愚蠢的), duckling (小鸭子), feather (羽毛), powerful (强大的).
板块 2:功能短语“活用”
短语
考点透视
once upon a time
故事专用开头,= long long ago。只用于过去时,不能与 now/tomorrow 连用。
pretend to do sth.
假装做某事。to 后面必须接动词原形。
make/keep/break a promise
许诺/守信/失信。promise 可作名词也可作动词:promise to do。
set ... free
释放……。free 是形容词作宾补。
instead of
代替,而不是。⚠️大坑:of 是介词,后接名词、代词或动名词 (doing)。
to one's surprise
令某人惊讶的是。类似结构:to one's joy(令某人高兴的是)。
板块 3:重点句型“解码”
1. 否定疑问句(表惊讶/反问)
◦ 原文:Didn't you know the time?
◦ 译法:难道你不知道时间吗?(暗示“你应该知道”)
◦ 答法:事实求是。知道就说 Yes, I did.(不,我知道);不知道就说 No, I didn't.(是的,我不知道)。
2. 感叹句(What 引导)
◦ 原文:What lovely clothes!
◦ 公式:What + adj. + 可数名词复数/不可数名词 (+ 主谓)!
◦ 对比:How lovely the clothes are! (How + adj. + 主谓)
3. 故事中的虚拟语气(了解)
◦ 原文:If someone set me free, I would make them rich.
◦ 含义:这是一种假设(妖怪被关着,还没被放),所以动词用了 set (did),would 表意愿。
板块 4:语法聚焦——一般过去时(叙事的灵魂)
1. 句式结构回顾
句式
结构
示例
肯定句
主语 + 谓语(过去式)
The mouse helped the lion.
否定句
主语 + didn't + 动原
The lion didn't eat the mouse.
一般疑问句
Did + 主语 + 动原?
Did the emperor like the clothes?
特殊疑问句
疑问词 + did + 主语 + 动原?
Where did you go?
2. 高频不规则动词“通关卡”(期末必考)
AAA型:let-let-let, put-put-put, read-read-read (读音变)
ABB型:catch-caught-caught, teach-taught-taught, buy-bought-bought
ABA型:come-came-come, become-became-become
ABC型:bite-bit-bitten, see-saw-seen, go-went-gone, take-took-taken
3. 难点突破:all alone vs lonely
• all alone:副词短语,表客观状态,“独自一人”(没人陪)。The house is all alone on the hill.
• lonely:形容词,表主观感受,“孤独的、寂寞的”(心里苦)。The old man feels lonely.
三、典例精讲(思维可视化)
例1(动词时态与语态)
The emperor ______ (ask) two officials to check the cloth yesterday, but they ______ (see) nothing.
解析:yesterday 是过去时标志。第一空填 asked;第二空,see 是不规则动词,过去式是 saw。
答案:asked; saw
例2(句型转换陷阱)
The fisherman set the genie free because he promised to do so. (对划线部分提问)
解析:对原因提问用 Why。注意原句是过去时,助动词用 Did。set 在这里是过去式(set-set-set),提问后要还原为动词原形 set。
答案:Why did the fisherman set the genie free?
例3(词义辨析)
The ugly duckling sat ______ in the corner, feeling very ______.
A. alone; alone B. lonely; alone C. alone; lonely D. lonely; lonely
解析:第一空修饰 sat(动词),表示“独自坐着”(客观),用 alone;第二空 feel 是系动词,后接形容词,表示“感到孤独”(主观),用 lonely。
答案:C
四、过关检测(分层闯关)
A层·基础通关(夯实双基)
1. 单词拼写:The hunter used a big n_____ to catch the lion.
2. 短语互译:做出承诺 ____________;代替 ____________
3. 句型转换:The mouse bit through the net.(改为否定句)
The mouse ______ ______ through the net.
B层·能力提升(语法攻坚)
4. 语法填空:The emperor was afraid ______ (wear) the "new clothes".
5. 单选:—Didn't you see the sign "No Smoking"? —______. I won't do it again.
A. Yes, I did B. No, I didn't C. Yes, I didn't D. No, I did
6. 完形填空:The lion was caught, but the little mouse set him ______ (freely, free).
C层·素养拓展(读写结合)
7. 微写作:请用英语写出《塞翁失马》的核心寓意(不超过15个词)。

五、参考答案与解析
1. net

3. didn't bite(⚠️注意:助动词 didn't 后必须用动词原形 bite,不能用 bit)
4. to wear(固定搭配 be afraid to do sth.)
5. B(事实是我没看见,所以用否定 No, I didn't. 翻译成“是的,我没看见”。)
6. free(set...free 是固定搭配,free 作宾补)
7. Bad luck may turn into good luck. / Good things can go wrong.
