情景导入
早晨的校门口，同学们从四面八方赶来：小杰坐地铁 3 号线，小雨爸爸开车送，浩浩骑共享单车，还有人干脆走路来。
英语老师做了个小调查："How do you come to school?"
答案五花八门：By subway! By car! By bike! On foot!
咦，为什么别的都用 by，走路却用 on foot？这一课我们就来学"交通方式"的说法，还要学会用英语聊交通规则。
核心词汇
交通方式类（注意都用 by，只有步行用 on foot）：
| 单词/短语 | 意思 | 例句 |
|---|---|---|
| by bus | 乘公交车 | I go to school by bus. |
| by subway | 乘地铁 | She goes to work by subway. |
| by train | 乘火车 | We go to Beijing by train. |
| by plane | 乘飞机 | They go to Sanya by plane. |
| by ship / by ferry | 乘轮船 / 渡轮 | You can go there by ship. |
| by bike | 骑自行车 | He goes to the park by bike. |
| by taxi | 乘出租车 | Let's go by taxi. |
| on foot | 步行 | I go to school on foot. |
交通规则类：
| 单词/短语 | 意思 | 例句 |
|---|---|---|
| traffic lights | 交通信号灯 | Look at the traffic lights. |
| slow down | 减速 | Slow down at a yellow light. |
| stop and wait | 停下等待 | Stop and wait at a red light. |
| go | 通行 | Go at a green light. |
句型与语法
核心问句：How do you go to...?（你怎么去……？）
- How do you go to school? — I go to school by bus. / On foot.
- How does your father go to work? — He goes to work by subway. （注意三单 goes！）
by + 交通工具，中间不加任何词：
- by bus ✅ by a bus ❌ by the bus ❌
建议句型：Let's go... / You can go...
- Let's go to the park by bike. （我们骑车去公园吧。）
- You can go there by the No. 15 bus. （你可以坐 15 路公交去。）
交通规则祈使句（红黄绿三句诀）：
| 信号灯 | 英语规则 |
|---|---|
| red light 红灯 | Stop and wait at a red light. |
| yellow light 黄灯 | Slow down and stop at a yellow light. |
| green light 绿灯 | Go at a green light. |
听说训练
交通方式小调查（问三个同学并记录）：
- A: How do you come to school? （你怎么来上学？）
- B: I usually come to school by bus. Sometimes I come on foot. （我通常坐公交，有时步行。）
- A: How does your mother go to work? （你妈妈怎么上班？）
- B: She goes to work by subway. （她坐地铁上班。）
红绿灯快答：一人喊颜色，一人说规则——Red light! → Stop and wait! / Green light! → Go!
辨析对比
- by + 交通工具是介词短语，放在句尾：I go to school by bike.
- 同样的意思也能用动词表达：I ride a bike to school. / I take a bus to school. / I walk to school.
- 对应关系：by bike = ride a bike；by bus = take a bus；on foot = walk；
- 注意主语三单时动词要变：He takes a bus. / She walks to school.
文化角
不同国家的交通很不一样：在英国和澳大利亚，汽车靠左行驶，过马路要先看右边；在德国，很多孩子骑自行车上学，自行车道非常完善；在美国，黄色的 school bus（校车）地位特殊——校车停车时，后面所有车辆都必须停下等待。
而我们杭州的地铁（subway，英式英语叫 underground）和公共自行车系统，也常让外国游客竖起大拇指！
易错点
- on foot 说成 by foot：I go to school by foot. ❌ → I go to school on foot. ✅（步行是唯一用 on 的）
- by 后加冠词：by a bus / by the bike ❌ → by bus / by bike ✅（by 后面直接跟交通工具原形）
- 三单形式忘变：How does he goes to school? ❌ → How does he go to school? ✅（does 已经"背走"了 s）
- 交通灯规则张冠李戴：黄灯是 slow down（减速），不是 go；听力题最爱在这里挖坑。
考点
- How do you go to...? 问答（by + 交通工具 / on foot）——单选、情景对话必考；
- on foot 与 by 短语的辨析（易错题第一名）；
- by bike = ride a bike、by bus = take a bus 的同义句转换（小升初高频）；
- 交通灯规则连线题：red—stop / yellow—slow down / green—go；
- 第三人称单数：How does she go...? — She goes... 的一致性。
