初二英语新教材Unit 2知识清单:can / could 的请求用法,家务与礼貌请求全讲透(含范文与自测)

各位家长好,我是长沙英语王若敏 Via 老师。

如果说 Unit 1 是"过去的事",那 Unit 2 就是"家里的事"——家庭生活 + 家务分工 + 礼貌请求。这个单元的语法核心是情态动词 can / could 的请求用法,是初中阶段最实用、最贴近日常生活的语法点——孩子终于可以用英语礼貌地说"请帮我……可以吗?"了。

三、核心语法:can 和 could 的请求用法

情态动词 can / could 在这个单元是重点中的重点——它不只是"能力",更是日常礼貌对话的桥梁。

(一)can 的三大用法(必考)

用法
含义
例句
能力
会、能够
I can sweep the floor.
请求
请你……
Can
 you help me?
许可
我可以……吗?
Can
 I watch TV now?

(二)could 的两大考点(必背)

1. 委婉请求(比 can 更礼貌)

  • Could you (please) pass me the salt?
  • Could you please help me with the dishes?

2. 过去能力(一般过去时里 could = was/were able to)

  • I could swim at the age of five.

(我五岁时就会游泳。)

(三)回答 Could 问句用 can 不用 could(铁律!)

  • — Could I use your bike?

— Yes, you can. ✅ — Yes, you could. ❌

为什么? Could 在委婉请求中是现在时态(只是语气更客气),不是过去时。回答时回到 can 即可。

(四)could 的所有用法(6 个层级)

  • 现在委婉请求
    :Could you please open the door?
  • 现在委婉许可
    :Could I borrow your pen?
  • 过去能力
    :I could ride a bike when I was five.
  • 过去委婉请求
    :He asked if I could help him.
  • 虚拟语气(高级)
    :If I were you, I could go.(九年级会学到)
  • could have done(本应能)
    :You could have told me earlier.

初中阶段重点掌握 1、2、3 三种。

(五)Could you please ... ? 三步否定回答

步骤
例句
1. 道歉
Sorry, I ...
2. 给原因
I have to ... / I'm busy with ...
3. 提出替代
Could you ask ... ? / Maybe next time.

完整示例:

  • — Could you please clean the living room?
  • — Sorry, I can't. I have to do my homework now. Maybe you can ask Dad?

四、写作专题:家务分工表(My Family Chores)

写作任务:用英语介绍家里的家务分工情况,60-80 词。

(一)写作思路——三段式

  • 开头
    :总述——In my family, everyone does chores.
  • 主体
    :分 2-3 个家人介绍具体分工(who does what when)
  • 结尾
    :表达感受——doing chores makes our home clean and sweet

(二)写作词汇宝箱

维度
词汇
家人
father, mother, brother, sister, grandma
时间
on school days, on weekends, every evening, after dinner
动作
sweep, fold, take out, make, wash, clean
感受
fair, helpful, happy, sweet

(三)写作黄金句型(必背 5 条)

  • 总述
    :In my family, everyone does chores.
  • 职责
    :My mother cooks delicious meals, and my father does the dishes after dinner.
  • 自己
    :On school days, I make my bed and take out the rubbish.
  • 周末
    :At the weekend, we clean the house together.
  • 感受
    :Doing chores makes our home clean and sweet. / I think everyone should help out at home!

(四)参考范文:My Family Chores

In my family, everyone does chores. My mother cooks delicious meals every day, and my father does the dishes after dinner. My little sister is only four, but she can put away her toys.

On school days, I make my bed and take out the rubbish. Sometimes I help my mother fold the clothes. On the weekend, we clean the house together — I sweep the floor, my father cleans the living room, and my mother tidies the kitchen.

Doing chores makes our home clean and sweet. I think everyone should help out at home!

(五)保底模板(考试直接套用)

In my family, everyone does chores.

On school days, I ______ (自己做的家务 1) and ______ (自己做的家务 2). My mother ______ (妈妈做的), and my father ______ (爸爸做的).

At the weekend, we ______ (周末一起做的家务). Doing chores makes our home ______ (形容词). I think everyone should ______!


五、易错点(这些坑千万别踩!)

  • housework 不可数
    :many housework(错)much housework(对)。但 chores 可数:do many chores。
  • 回答 Could 用 can 不用 could
    :Yes, you could.(错)Yes, you can.(对)。
  • could 是现在时态
    :could 在请求里不表示过去。Could you please ... 是现在的礼貌。
  • could 表过去能力用 was/were able to 替代
    也可以:I could swim = I was able to swim(过去)。
  • borrow 和 lend 方向相反
    :I borrow a book from you.(我向你借书)/ You lend a book to me.(你借我书)。
  • take out the rubbish 不加冠词 a
    :the rubbish(对)a rubbish(错)。

六、自测 3 题(检验你是否真的懂了)

第 1 题 — ______ I use your ruler, Lily? — Sure, you ______. But please give it back soon.

A. Could; canB. Can; couldC. Could; couldD. Can; can

答案:A 解析:问句用 Could 表委婉,回答用 can

第 2 题 — Could you please pass me the salt? — ______

A. Yes, you could.B. No, thanks.C. Sure, here you are.D. Sorry, you couldn't.

答案:C 解析:Sure, here you are. 是正确答语

第 3 题 My sister ______ to cook when she ______ only five years old.

A. could; isB. could; wasC. can; isD. can; was

答案:B 解析:过去能力用 could;过去时用 was


七、本单元口语实战(每天练 3 遍)

情境
句型
想看对方的书
Could I borrow your book, please?
请对方帮忙倒垃圾
Could you (please) take out the rubbish?
邀请对方来家里

答应帮忙

Unit 2 的 can/could 礼貌请求是英语"开口说"的真正起点。把"Could I / Could you"两个句型每天默念 10 遍,写作把黄金句型 5 条抄一遍,这一篇就稳了。

下一篇我们讲 Unit 3 Same or Different?——比较的话题,形容词和副词的比较级,期中考的"分值大户",单选完形写作三大题型都考。

这份 Unit 2 清单,怎么用最划算

Via 老师划重点
Unit 2 的核心是「can / could 的请求用法」,写作落点是「家务分工表(My Family Chores)」。建议用法:先让孩子把「核心词汇 + 必背短语」两张表扫一遍(约 15 分钟),再跟着语法精讲过一遍例句,然后当场做「自测题」——做错的题,回到对应的语法小节重看。最后把「易错点」当检查表用,一条条对照自己的作业。

📚 完整版资料:本单元知识清单已整理成 PDF 打印版 + Word 可编辑版,含完整词汇表、语法精讲、范文与全解全析,约 10 页。公众号后台回复 「八上U2」 即可领取。

八上 8 个单元的清单会陆续更新,跟学校进度走,本周学到哪单元就打印哪单元,别提前囤着不消化。
