本课目标

学完本课，你能够和家人、室友或共同生活的人分配家务并确认责任，具体做到：

• 询问一项家务轮到谁做；
• 区分“不得不做”“为了完成目标需要做”和“原先约定由谁做”；
• 在分工不均时提出交换；
• 最后复述每个人负责的事项，避免双方理解不同；
• 写一条40—70词的分工消息，并完成一段60—90秒的无稿协商。

本课只有一个现实任务：分配家务并确认责任。

热身

先用你已经会的英语简单回答，不必写完整句子：

1. 你最常做哪两项家务？哪一项最容易被忘记？
2. 两个人都以为“对方会做”时，怎样确认才能避免争吵？

场景词汇

• laundry 待洗或正在洗的衣物；洗衣这件事
• recycling 可回收物；回收处理
• unload the dishwasher 把洗碗机里的干净餐具取出
• fold the laundry 把洗好的衣物叠好
• chore list 家务清单

The Saturday list

It is Saturday morning at Maya and Ben's home. Their daughter is finishing her homework at the kitchen table while Maya and Ben look at the chore list on the refrigerator.

Maya: Before we start the day, we need to decide who's doing what. The laundry, bathroom, groceries, dishes, and recycling are all still on the list.

Ben: Right. Whose turn is it to clean the bathroom?

Maya: I think it's your turn to clean it. I did it last weekend.

Ben: You're right. And I thought you were supposed to take the recycling downstairs.

Maya: I am. I also have to pick up the groceries before noon.

Ben: Sorry, what was that? I didn't catch the time.

Maya: Before noon. The pickup time is between eleven and twelve.

Ben: Got it. I have to finish my lesson plans this morning, but I can take the recycling down first if that helps.

Maya: That would help, thanks. Then you're taking the recycling.

Maya: Thanks. I'm supposed to start the laundry, right?

Ben: Yes, and I'm doing the dishes after breakfast.

Maya: Just to check, you mean unloading the clean dishes first?

Ben: Exactly. Then I'll load the breakfast dishes. Do you want to trade the bathroom for the laundry?

Maya: No, let's keep those two as they are. You have three tasks, and I have two, but the grocery trip takes longer.

Ben: Fair enough. So you're picking up the groceries and doing the laundry, and I'm cleaning the bathroom, doing the dishes, and taking out the recycling, right?

Maya: Almost. We need to fold the laundry together after lunch.

Ben: Let me make sure I've got this right: I have the bathroom, dishes, and recycling. You have the groceries and laundry. We fold everything together.

Maya: That's it. Now the list is clear.

By the end of the afternoon, every item on the list is checked off.

本课负荷说明

本课有七项全新主动表达：第1—7项。第8—10项来自第4课，本课需要在新场景中主动检索。第4课的 I didn't catch… 不重复列入本课十项核心表达，但会在第7部分的新情境中完成近距离检索。

1. Whose turn is it to …?

这次轮到谁……？用于共同承担、轮流进行的事情，语气中性，适合家人、室友或熟悉的同事。

Whose turn is it to take out the trash?

2. It's my / your turn to …

这次轮到我／你…… 用于说明当前轮次。对不熟悉的人直接说 It's your turn 可能显得生硬；先确认旧安排更稳妥。

I cooked yesterday, so it's your turn to cook tonight.

3. We need to decide who's doing what.

我们需要决定谁负责什么。适合在开始一组共同任务前把分工说清楚，语气中性。

We have thirty minutes before the event. We need to decide who's doing what.

4. I have to … before …

我必须在……之前…… 用于说明有截止时间、规则或现实限制。

I have to return the key before five.

5. I thought you were supposed to …

我原以为按约定应该由你…… 用于核对先前分工。I thought 能表明这是你的理解，但如果语气很重，仍可能像责备；适合先确认事实。

I thought you were supposed to call the repair office.

6. Do you want to trade?

你想交换一下吗？用于交换任务、座位或轮次，语气随意到中性。

I'll wash the dishes, and you take out the trash. Do you want to trade?

7. So you're doing …, and I'm doing …, right?

所以你负责……，我负责……，对吗？用于在分工结束时快速确认双方责任。

So you're writing the message, and I'm making the call, right?

8. Just to check, you mean …?

确认一下，你指的是……吗？这是第4课词块 CH023，用于合作式确认一个具体细节。

Just to check, you mean this Saturday, not next Saturday?

9. Sorry, what was that?

抱歉，你刚才说什么？用于整句都没听清。这是第4课的 CH024。

Sorry, what was that? The vacuum is loud.

10. Let me make sure I've got this right.

我确认一下自己有没有记对。这是第4课词块 CH027；后面应复述全部关键分工，而不只说 right?。

Let me make sure I've got this right: you bring the food, I bring the drinks, and we arrive at six.

Don't Say It That Way

容易说出的句子	更自然的表达
Who's turn is it?	Whose turn is it?
You clean the bathroom.	I thought you were supposed to clean the bathroom.
You do what?	Just to check, which task are you doing?
I am suppose to do it.	I am supposed to do it.
We exchange?	Do you want to trade?

本课只建立一个语法系统：怎样说明一件事为什么要做，以及原先由谁负责。 三种结构后面都接动词原形，但说话者选择它们的原因不同。

A. have to：外部要求或现实限制

I have to pick up the groceries before noon.
Ben has to finish his lesson plans this morning.

截止时间、工作要求或客观情况让这件事不能不做。主语是第三人称单数时用 has to。

B. need to：完成目标所需的步骤

We need to decide who's doing what.
We need to fold the laundry after lunch.

说话者把它看成实际需要，不一定来自正式规定。主语是第三人称单数时用 needs to。

C. be supposed to：已有约定、规则或角色期待

Maya is supposed to start the laundry.
Ben is supposed to clean the bathroom.

重点是“先前已经这样安排或大家这样期待”。形式随主语变化：

在核心词块 I thought you were supposed to… 中，were supposed to 指先前理解的安排。现阶段把整句作为自然的核对方式使用即可。

主语	have to	need to	be supposed to
I / you / we / they	have to	need to	am / are supposed to
he / she / Ben / Maya	has to	needs to	is supposed to

三种结构后面都用动词原形：

has to clean
needs to leave
is supposed to call

不要写成 has to cleans 或 is suppose to call。

D. 否定形式不要混淆

You don't have to do the dishes today.
You don't need to do the dishes today.

两句都表示“今天没有必要做”，不是“禁止做”。

You aren't supposed to put this pan in the dishwasher.

这句表示按照规则或说明不该这样做。以上仍属于同一个“义务与责任”系统；本课不增加其他情态动词作比较。

快速判断方法

先问自己一句：

• 有明确截止时间、规定或现实压力吗？→ have to
• 这是完成目标所需的一步吗？→ need to
• 这是之前约好的分工或角色期待吗？→ be supposed to

真实对话中有时不只一种说法合语法。练习会给出清楚的语境线索；自由表达时，应选择最符合你想强调的原因的一项。

本课网页已配有完整对话、逐句播放和影子跟读。先用正常对话完成理解，再用逐句模式模仿人物重音。

分工时，听者最需要听清的是谁和什么任务。把这两个信息词读清楚，功能词可以自然变轻：

BEN is supposed to clean the BATHROOM.
MAYA has to pick up the GROCERIES.
WE need to fold the LAUNDRY.

自然语流中的 to 通常较轻。你可能听到 have to 接近 /hæf tə/，supposed to 的两个词也会紧密连接。不要为了模仿而写成 hafta 或 supposta；书面形式仍然是 have to 和 supposed to。

对比重音

换一个重读词，纠正的信息也会改变：

I'M supposed to take out the recycling.
（不是你，是我。）

I'm supposed to take out the RECYCLING.
（不是普通垃圾，是回收物。）

朗读与录音

读下面三句各两遍。第一遍重读人物，第二遍重读任务：

1. Maya is supposed to do the laundry.
2. Ben has to clean the bathroom.
3. We need to put the groceries away.

回听时只检查：不看文字，你能否听清负责人和任务？不需要模仿特定口音。

---

A. 理解检查

判断正误。正确写 T，错误写 F。

1. Maya and Ben are deciding how to divide today's chores.
2. Ben cleaned the bathroom last weekend.
3. Maya has to pick up the groceries before noon.
4. Ben and Maya decide to trade the bathroom and laundry.
5. They plan to fold the laundry together.

B. 阅读一份新的家务安排表

下面是另一户家庭的周六安排，不是主对话内容。读表后回答问题。

Saturday Chore Plan

Person	Before noon	After lunch	Note
Riley	Start laundry before 10:00; pick up groceries at 11:00	Wipe the kitchen counters	The laundry room closes at 6:00.
Jordan	Take out recycling before 9:00; clean the bathroom	Vacuum the living room	The recycling truck comes at 9:15.
Together	Put the groceries away at 11:45	Fold the laundry	Check both jobs off the list.

回答：

1. Who is supposed to take out the recycling?
2. Which task does Riley have to start before 10:00?
3. What do Riley and Jordan need to do together at 11:45?
4. Does Jordan need to vacuum the living room before lunch?
5. Why does the recycling have to go out before 9:00?

C. 选择责任的来源

根据括号里的意义线索，用 have to、need to、be supposed to 的正确形式填空。每题只选最符合线索的一项；第7—8题括号还指定了需要变成否定式的结构。

1. The truck arrives at 9:15, so Jordan __________ take out the recycling before nine. (external deadline)
2. Riley and Jordan __________ decide who is doing each job before they begin. (practical step)
3. They agreed yesterday that Riley __________ start the laundry. (earlier agreement)
4. Maya's pickup window ends at noon, so she __________ collect the groceries before then. (external deadline)
5. Ben __________ clean the bathroom because that is his task on today's list. (assigned responsibility)
6. To finish the laundry, Maya and Ben __________ fold the clothes after lunch. (practical step)
7. Today is not your turn, so you __________ clean the bathroom. (no external requirement; negative have to)
8. This cup is hand-wash only. You __________ put it in the dishwasher. (contrary to instructions; negative be supposed to)

D. Unit 1 repair phrases — near retrieval

Close Lessons 1—4 and cover the expression list above. There is no phrase bank. Read each new situation and begin speaking within five seconds. Do not translate it first.

1. Your partner says, “I'll take the recycling out after lunch.” You expected it to happen before lunch. Check the timing with one cooperative question.
2. A vacuum starts just as your partner explains the whole plan. You hear none of the sentence. Ask them to repeat it politely.
3. You hear the sentence, but you miss only the name of the chore. Tell your partner exactly which part you did not hear.
4. Your partner gives you three details: Maya—laundry; Ben—bathroom; both—groceries. Repeat all three details so your partner can confirm your understanding.

本题的情境没有中文、目标原句或首字母提示。只有在不回看表达表的情况下主动说出第4课词块，才算完成 CH023、CH024、CH025、CH027 的近距离R。

E. 完成家务协商

从方框中选择最合适的表达。每项只用一次。

Whose turn is it · my turn · who's doing what · supposed to · trade · right

1. We have six jobs and only two hours. We need to decide __________.
2. __________ to clean the kitchen?
3. You cooked last night, so it's __________ to cook tonight.
4. I thought Alex was __________ call the landlord.
5. This task takes longer than mine. Do you want to __________?
6. So you're doing the laundry, and I'm doing the dishes, __________?

F. 把意思说得自然

根据情境写出自然英文，不必逐字翻译。

1. “这次轮到谁把回收物拿出去？”
2. “我必须在五点前取钥匙。”
3. “为了完成打扫，我们需要给地板吸尘。”
4. “我原以为按分工应该由你洗餐具。”
5. “你想交换一下吗？”
6. “所以你负责卫生间，我负责洗衣服，对吗？”

G. 实用互动写作

阅读情境，写一条40—70词的英文消息：

你和室友 Sam 今天要完成四项家务：买杂货、洗衣服、打扫卫生间、处理回收物。回收物必须在上午九点前拿出去。原先约定 Sam 打扫卫生间。请提出一份公平分工，并让 Sam 确认或更改一项。

写完后，把消息交给真人伙伴或语音助手。请对方只改变一项分工，再写一条20—40词的回复，完整确认最终计划。两条消息合起来才算完成互动写作。

---

第一步：做一份与你有关的简短安排

写下今天或本周真正需要完成的4—6项家务。如果你独居，可以把“分工”改为给不同日期或时间段分配任务；重点仍是说明每项任务的责任和必要性。

至少标出：

• 一项有截止时间、需要用 have to 说明的任务；
• 一项为了完成目标、需要用 need to 说明的任务；
• 两项已经约定负责人、需要用 be supposed to 说明的任务。

第二步：录制60—90秒说明

不要写完整稿，只看“任务—负责人—原因—确认”四类关键词。说明：

1. 有哪些家务；
2. 哪项轮到谁做；
3. 为什么某项必须在特定时间前完成；
4. 是否需要交换；
5. 最后完整确认每个人负责什么。

录音两次。第二次减少停顿，但不要为了速度省略负责人或截止时间。

第三步：随机互动

把下面的指令交给真人学习伙伴或语音助手：

You are sharing six household tasks with me today. Do not write my sentences for me. Ask me to divide the tasks first. After I suggest a plan, secretly choose one action: say that one task has a deadline, remind me that one task was already assigned to me, ask to trade one task, or correct one detail in my summary. Do not tell me your choice in advance. Continue until I repeat the complete final plan accurately.

你需要根据对方未预告的变化继续协商，并使用三种责任表达中的至少两种。最后必须复述全部分工；只念预先写好的安排不算完成随机互动。

72小时后的间隔复习

三天后，不看本课正文或表达表：

1. 随手写下四项家务和两个人名；
2. 用硬币或随机数把任务分给两人；
3. 在45秒内开始说明谁负责什么；
4. 分别用 have to、need to、be supposed to 各说一句；
5. 请伙伴临时改一项，再完整确认最终安排。

保存这次录音，与今天的第二次录音比较。如果三种结构的理由仍然混淆，重做第7部分B和C。

---

为每一项选择：能做到／还不稳定／需要重学。

• 我能询问一项家务轮到谁做。
• 我能用 have to 说明截止时间、规则或现实限制。
• 我能用 need to 说明完成目标所需的步骤。
• 我能用 be supposed to 说明先前约定或已有分工。
• 我不会把 don't have to 错解成“禁止做”。
• 我能提出交换任务，而不是只说分工不公平。
• 我能在没有中文或原句提示时调用第4课的四个修复词块。
• 对方临时改变一项责任后，我能继续互动并完整确认最终分工。
• 我能写出一条40—70词的分工消息，并回复一次变化。

如果有两项以上选择“需要重学”，先重做第7部分C、D和G，再完成72小时后的间隔复习。
