热身

先用你已有的英语简单回答：

1. 当你很想参加，但还不能确定时，你通常会立刻答应，还是先说明不确定？
2. 拒绝朋友的邀请时，怎样既说清楚，又不显得冷淡？

A Sunday concert

Aisha and Lena met briefly at a workshop and recently ran into each other again while Daniel was visiting the arts center. On Thursday evening, they are talking with him outside Maple Court about a free outdoor concert on Sunday.

Part A — The invitation

Aisha: Lena and I are going to an outdoor concert on Sunday. You should come with us.

Daniel: I'd love to, but I have a project due Monday morning.

Lena: You could join us later. The music starts at six, but it goes until nine.

Daniel: I might be able to come after I finish the first draft. Where is it?

Aisha: On the lawn behind the Harbor Street Arts Center. Would you like to join us if you're free?

Daniel: I'd like to. Let me see if I can get most of the work done on Saturday.

Lena: No pressure. We just need a clear answer before we leave on Sunday.

Daniel: That's fair. I'll message you by three on Sunday afternoon.

Aisha: Perfect. And if work takes longer, maybe another time.

Part B — A clear answer

At 2:40 on Sunday afternoon, Daniel sends a group message.

Daniel: Hi, you two. I'm afraid I can't make it tonight. The project is taking longer than I expected, and I don't want to arrive for only the last few minutes.

Aisha: No problem. Thanks for letting us know before we leave.

Lena: Absolutely. Maybe another time.

Daniel: Thanks for understanding. I hope you have a great evening.

Aisha: Thanks. Good luck with the project.

That evening, Aisha and Lena go to the concert as planned, while Daniel stays home to work. Daniel has given them a clear answer, so nobody is waiting for another message.

本课负荷说明

本课展示10项核心表达。第1—7项是全新主动项目，供第12课安排整合检索；第8项复现邀请表达，第9—10项是高频基础表达唤醒。本课只配置学习和迁移机会，不自行宣称学习者已经完成R。

1. You should come with us.

你应该和我们一起去。朋友间热情、随意的邀请。对不熟悉的人可能显得过于直接，可改用第8项。

We're going to the night market. You should come with us.

2. You could join us later.

你可以晚一点加入我们。用于提供一个可选择的方案，不表示对方必须这样做。

You could meet us after dinner.

3. I might be able to …

我或许能…… 用于说明尚未确定的可能性。它不是接受；如果对方需要做安排，应补充何时给明确答复。

I might be able to come after seven. I'll let you know by noon.

4. I'd love to, but …

我很想……，不过…… 先表达积极态度，再说明限制。适合朋友和熟悉的同事。

I'd love to, but I already have plans.

5. Let me see if I can …

我先看看能不能…… 用于暂时不能确定时争取一点时间。后面要给出明确回复时间，不能让对方一直等。

Let me see if I can move one appointment. I'll tell you this afternoon.

6. I'm afraid I can't make it.

恐怕我参加不了。礼貌、中性，适合朋友、邻居和一般同事。make it 在这里指“能到场”。

I'm afraid I can't make it on Friday.

7. Maybe another time.

下次再约。用于友好结束婉拒，适合确实愿意以后再约的情况；如果你并不想再约，不必作虚假承诺。

I can't make it this week. Maybe another time.

8. Would you like to join us?

你愿意加入我们吗？复现此前学过的礼貌邀请功能。比 You should come with us 更适合不太熟悉的人。

A few of us are having lunch. Would you like to join us?

9. No pressure.

不用有压力。基础表达唤醒，用于明确告诉对方可以自由决定。语气应真诚，不能说完后继续逼问。

Let me know tomorrow. No pressure.

10. Thanks for letting me know.

谢谢你告诉我。基础表达唤醒，用于接受对方的明确回复，不让婉拒变得尴尬。

I'm sorry you can't come, but thanks for letting me know.

Don't Say It That Way

容易说出的句子	更自然的表达	原因
I maybe come.	I might be able to come.	maybe 不能直接替代句中的情态动词
I might come, so count me in.	I might be able to come. I'll confirm by noon.	might 不是确认参加
I cannot join your activity.	I'm afraid I can't make it.	日常邀请中更自然
I don't want.	I'd love to, but I already have plans.	先回应邀请，再说明限制

---

本课只建立一个语法系统：在社交邀请中表达热情建议、可选方案和不确定可能性。 三个情态动词后面都接动词原形。

A. should：友好、较强的建议或邀请

You should come with us.
You should try the afternoon class.

说话者认为这是个好主意。在朋友间可以很热情，但它仍比普通邀请更有推动力；对新邻居或普通同事，Would you like to…? 往往更稳妥。

B. could：一种可选择的办法

You could join us later.
We could meet near the entrance.

could 提供选项，不表示这就是唯一方案，也不表示已经决定。

C. might：尚未确定的可能性

I might come after seven.
Lena might bring a friend.

might 表示可能，但说话者还没有确认。主人需要人数时，应继续问：

When can you let me know?

回答者应给出明确时间：

I'll confirm by three.

D. 形式

主语	情态动词	动词原形
You	should	come
You	could	join
I	might	arrive

不要加 to，也不要给动词加 -s：

You should come.
She might join us.

不要写成 should to come 或 she might joins。

快速辨析

选择 should、could 或 might。每题只有一个最符合语境的答案。

1. I strongly think this event would be fun for you. You __________ come with us.
2. You cannot arrive at six, but arriving at seven is one possible plan. You __________ join us later.
3. I have not checked my work schedule, so I __________ be able to come.
4. We do not have to meet at the gate; the café is another option. We __________ meet there.
5. Nina has not answered yet. She __________ come, but we don't know.
6. This band is one of your favorites. You really __________ see them live.

---

本课网页已配有完整对话、逐句播放和影子跟读。重点听邀请、保留可能性和明确婉拒在语气上的区别。

热情邀请的重音

邀请朋友时，通常突出活动或 come，语调友好：

You should COME with us.
You should see this BAND.

如果整句都很重，should 可能听起来像施压。可以比较：

You SHOULD come with us.
You should COME with us.

第二句通常更像热情邀请。

might的保留语气

说 might 时不要用已经确定的兴奋语气，后面可短暂停顿，再补充确认时间：

I MIGHT be able to come … / I'll confirm by three.

朗读与自录

录制下面三句。回听时判断：第一句是否热情，第二句是否像提供选项，第三句是否清楚表达“不确定”。

1. You should come with us.
2. You could join us after dinner.
3. I might be able to come, but I'll confirm tomorrow.

不要模仿特定口音。目标是让听者听清你的态度和确定程度。

---

A. 理解检查

判断正误。正确写 T，错误写 F。

1. The concert is on Saturday.
2. Daniel has work due on Monday morning.
3. Lena says Daniel must arrive before six.
4. Daniel's first answer is a definite yes.
5. Daniel promises to send a clear answer by three on Sunday.
6. He sends his refusal before the promised time.

B. should、could还是might

用 should、could 或 might 完成句子。

1. This book club is very friendly. You __________ come with me next week.
2. If six is too early, you __________ meet us at seven.
3. I have to check whether I am working, so I __________ be able to join you.
4. We __________ sit outside, or we can get a table inside.
5. Marta has another appointment. She __________ arrive late.
6. You love old photographs. You __________ visit this exhibit.

C. 这句话表示什么？

选择最准确的功能：A 热情建议／邀请；B 可选方案；C 尚未确定的可能性。

1. You should come to the picnic. ___
2. You could take the later bus. ___
3. I might be free after eight. ___
4. We could have coffee instead. ___
5. Sam might join us. ___
6. You should meet Lena. ___

D. 把婉拒补完整

从方框中选择，每项只用一次。

I'd love to, but · Let me see if I can · I'm afraid I can't make it · Maybe another time · Thanks for letting me know

1. “____________________ I already have plans on Sunday.”
2. “____________________ finish the report tonight. I'll confirm tomorrow morning.”
3. “____________________ this evening. I have to work late.”
4. “I won't be free this weekend. ____________________.”
5. A: “I can't join you tonight.” B: “No problem. ____________________.”

E. 关系与语域选择

每题选择更合适的一项。

1. 你邀请一位很熟的朋友去听他喜欢的乐队：

   • a. You should come with us.
   • b. Your attendance is requested.

2. 你邀请刚认识的邻居参加楼里的简单聚会：

   • a. You have to come with us.
   • b. Would you like to join us?

3. 熟悉的同事邀请你参加周五晚餐，但你已经有安排：

   • a. I'd love to, but I already have plans.
   • b. No.

4. 朋友说自己可能参加，但你需要提前订票：

   • a. Great, I'll buy your ticket now.
   • b. When can you let me know for sure?

5. 对方已经明确婉拒：

   • a. Thanks for letting me know.
   • b. Are you sure? You really should change your plans.

F. 独立阅读：三条邀请回复

下面的邀请与回复不属于主对话。

Invitation
A few of us are going to the Riverside food market on Saturday at 11:00. Would you like to join us? Please tell me by Friday evening because I need to reserve a table for lunch.

Reply 1 — Jordan
Yes, I can come. I'd love to join you.

Reply 2 — Priya
I might be able to join you after noon. Let me check one appointment, and I'll give you a definite answer by Friday at four.

Reply 3 — Alex
I'm afraid I can't make it on Saturday. Thanks for inviting me, and maybe another time.

回答：

1. Who has definitely accepted?
2. Who has definitely declined?
3. Whose answer is still uncertain?
4. When will that person give a definite answer?
5. Why does the organizer need answers by Friday evening?
6. Can the organizer treat Priya as confirmed yet? Why or why not?

G. 实用互动写作

一位熟悉的同事邀请你参加周六下午的桌游活动。你很想去，但必须先确认一项家庭安排。写一条40—70词的英文回复：

• 先积极回应邀请；
• 明确表示目前还不确定；
• 说明你何时会给最终答复；
• 不要让对方把你算作已确认参加。

把回复交给真人伙伴或语音助手。请对方随机回复以下一项，但不要提前告诉你：

• they need a final answer two hours earlier;
• the activity will start one hour later;
• no reservation is needed after all.

收到变化后，再写25—45词，确认新的时间或给出明确接受／婉拒。两条消息共同构成互动写作证据。

H. Delayed retrieval from Lesson 9

Close Lesson 9 and do not look at its expression list. Read each new situation once and begin speaking within five seconds. There is no phrase bank, Chinese translation, target wording or first-letter cue.

1. Check whether a familiar coworker's Tuesday lunch period is open.
2. Find out whether a friend already has something scheduled for Saturday morning.
3. Wednesday is impossible. Offer Thursday as the replacement.
4. You both agree on six o'clock at the station. State the agreed time and place in one short sentence.
5. The time changed, but you hope to keep the west entrance. Check whether that unchanged location is acceptable.
6. The Sunday eleven-o'clock arrangement is complete. End the exchange with a short, friendly closing.

这些题只为第9课六项新词块配置近距离检索机会。功能相同的表达可以完成沟通；只有实际无提示说出对应词块，才登记该词块的R。

---

任务一：60—120秒无稿回应

选择一个你真实可能收到的邀请：朋友聚餐、同事活动、邻里聚会或户外活动。只写“关系—活动—限制—答复时间”四类关键词，然后独自扮演邀请者和受邀者录音：

1. 发出邀请，再切换角色回应；
2. 在两边的台词中使用 should / could / might 中适合情境的至少两项；
3. 如果不能立刻确定，给出明确回复时间；
4. 最后明确接受或婉拒，不留下悬而未决的承诺。

任务二：随机关系互动

把下面指令交给真人伙伴或语音助手：

Choose one relationship without telling me first: close friend, familiar coworker, or new neighbor. Invite me to a simple social activity. After my first reply, randomly add one change: a later start, a ticket deadline, or a different day. Do not write my lines for me. If I only say I might come, ask when I can confirm. Continue until I give a definite answer and you respond naturally.

你需要根据关系选择热情或较礼貌的说法，根据变化提出可选方案，并在结束前明确“参加／不参加”。如果对方仍在等待你的答复，任务尚未完成。

三天后的间隔复习

三天后不要看本课表达表：

1. 用一句话热情邀请熟悉的朋友；
2. 为无法准时到场的人提供一个可选方案；
3. 说一句不确定答复，并补充确认时间；
4. 分别对朋友和熟悉的同事作一次自然婉拒；
5. 录制60秒，把其中一次婉拒改成明确接受。

保存两次录音，比较自己是否把 might 错说成了确定答复。

---

为每项选择：能做到／还不稳定／需要重学。

• 我能用 should 热情建议熟悉的人参加活动，而不把它说成命令。
• 我能用 could 提出可选择的时间或参加方式。
• 我能用 might 表达未确定的可能性，并知道它不是接受。
• 我能在说“可能参加”后给出明确回复时间。
• 我能用词块自然接受或婉拒邀请，而不是只说 yes / no。
• 我能根据朋友、熟悉同事和新邻居调整语气。
• 我能在收到临时时间变化后重新回应。
• 我能在互动结束前给出明确答复，不留下待兑现承诺。
• 我完成了网页正常对话和逐句跟读，并能在不看文字时听懂Daniel最后是否参加。

如果有两项以上选择“需要重学”，先重做第5部分和第7部分B、D、E，再完成三天后的间隔复习。
