③ 本质理解
动名词与不定式 是小托福 B2 阶段的核心语法点。它解决的问题是：当你想表达时间、状态、条件或修饰关系时，动词该怎么变形。不要死背规则，要先理解它在句子里承担什么功能——是描述习惯？是讲过去？是预测未来？还是给名词加修饰？
小托福语言形式与含义部分（Language Form and Meaning）约 30% 的题目直接考这个点。
④ 变形与用法表
| 规则 | 说明 | 例句 |
|---|
| 后接 doing | enjoy, finish, avoid, mind, suggest, practice, keep | I enjoy shopping. / Avoid wasting money. |
| 后接 to do | want, hope, decide, plan, expect, would like, agree | They expect shoppers to notice. |
| 后接 sb to do | want, ask, tell, encourage, expect, advise | Shops encourage customers to buy. |
| stop doing vs stop to do | stop doing = 停止做；stop to do = 停下来去做 | He stopped talking. / He stopped to talk to me. |
⑤ 三大题型用法
听力理解 Listening
校园对话/通知/讲座里，动名词与不定式 常出现在老师布置任务、通知时间、解释规则时。抓标志词。
语言形式 Language Form
四选一填空：给句子挖空，选正确变形。考点就是上面变形表里的规则。
阅读理解 Reading
课文/广告/信件里出现时，它承载关键信息（时间、条件、原因）。读题时先定位它。
⑥ 易错陷阱（高频丢分点）
- ① enjoy 后接 doing： ✗ I enjoy to shop. → ✓ I enjoy shopping。enjoy/finish/avoid/mind/practice 都接 doing。
- ② want/expect 后接 to do： ✗ I want going. → ✓ I want to go。want/hope/decide/plan/expect 接 to do。
- ③ make sb do（不加 to）： This makes people walk slowly（make + 宾语 + 动词原形）。但被动要加 to：People are made to walk slowly.
- ④ advise sb to do： Experts advise shoppers to make a list.（advise 后接 sb to do）。
⑦ 小托福考点拆解
| 题型 | 怎么考 | 解题策略 |
|---|
| 听力对话 | 两人讨论计划/规则，动名词与不定式 出现在答句 | 听第二个人的回答，抓动词变形 |
| 语言形式 | 四选一：给动词选正确形式 | 先找时间标志词，再定时态 |
| 阅读理解 | 问某句话的含义/原因 | 定位 动名词与不定式 所在句，答案就在前后一句 |
⑧ 必背例句（5 句）
1. Many teenagers enjoy shopping, but do you know how shops make you spend money? Retailers use psychology to encourage customers to buy more.
2. For example, they arrange the most expensive products at eye level.
3. They expect shoppers to notice them first.
4. Stores often play soft music; this makes people walk slowly and spend more time inside.
5. Bigger shops try to put the bakery near the entrance — the smell of fresh bread makes customers feel hungry, so they buy more food.
这 5 句来自 Unit 10 课文，熟读后能脱口而出，考试时直接套用。
⑨ 口语实战句型
口语 · 聊购物
Do you enjoy shopping?
I enjoy window shopping, but I do not like spending money. I usually plan to buy only what I need.
enjoy doing / plan to do 自然嵌入。
写作 · 消费建议
Experts advise shoppers to make a list. If you avoid buying things you do not need, you can save money.
advise sb to do / avoid doing 是 B2 写作加分句。
听力 · 商店广播
We encourage customers to use the entrance on the left. Please avoid using the elevator if you are in a hurry.
encourage sb to do / avoid doing 是服务用语高频。

㉕ 推荐拓展资源
- ETS 官方小托福页面：ets.org/toefl_junior（官方样题、分数对照）。
- 可汗学院英语语法专区（免费）：按 A1–B2 级别选练。
- 每天 15 分钟：BBC Learning English 6 Minute English，练听力与词汇。
- 写作练习：用本单元句型写 3 句日记，发给老师或自己对照范文。
㉖ 一页纸总结（Cheat Sheet）
本语法点一句话总结：
- 用什么结构：[动词变形]
- 什么时候用：[时间/场景标志]
- 肯定：主语 + 变形 + 宾语
- 否定：主语 + 助动词 + not + 原形
- 疑问：助动词 + 主语 + 原形？
- 最常见错点：[三单 s / 时间标志 / 不规则过去分词]
- 记忆口诀：看到标志想时态，看到主语想三单，看到完成想 have done。
把这张 cheat sheet 打印出来贴在书桌前，做题前扫一眼。一周后你会发现它已经长在脑子里了。
㉗ 与其他语法点的联系
- 时态要和时间状语一致：看到 yesterday 用过去，看到 already 用完成。
- 主谓一致：第三人称单数主语，一般现在时动词加 s。
- 被动语态：be + 过去分词，时态由 be 动词体现。
- 从句中的时态：主句过去时，从句通常也用过去时（间接引语规则）。
- 情态动词后永远接动词原形，不管主语是谁。
㉘ 教师批注：这个语法点怎么考
小托福语言形式与含义部分（Language Form and Meaning）约 30 道题，每题给一个句子挖空，从四个选项中选正确变形。监考老师多年经验：80% 的题可以靠"标志词"秒选——看到 every day 就一般现在，看到 yesterday 就一般过去，看到 already 就现在完成，看到 if + 现在就第一类条件句。剩下 20% 考不规则变形和主谓一致，必须靠背。
阅读部分考这个语法点时，通常不直接问"这是什么时态"，而是问"这句话暗示了什么"或"为什么作者用这个词"。这时你要识别：被动语态 = 强调动作而不是人；现在完成 = 强调对现在的影响；情态动词 = 表达建议/规则/可能性。
考场提醒：涂卡前再扫一眼主语是不是第三人称单数，动词有没有加 s；否定句和疑问句里助动词后面的动词是不是原形。这两个错误中国学生每年丢分最多。
