语法总结
疑问词 + to do
课文里的 I'll tell you where to get off. 把 where 和 to do 连在一起，表示“该在哪儿下车”。这类结构既简洁，又很适合出现在口语和叙事里。
相似句：
- He showed me where to wait for the bus.
- I didn't know how to get back home.
as far as we go 的固定表达
This is as far as we go. 不是单纯比较距离，而是“我们只能到这儿为止”。这种结构常用来表示范围、限度或终点。
相似句：
- This is as far as I can help you today.
- We walked as far as the station and then turned back.
分词短语作伴随状语
Looking round, I realized... 里 Looking round 不是完整谓语，而是伴随主句动作出现的分词结构，主语仍然是 I。
相似句：
- Turning back, she saw the bus leaving.
- Looking out of the window, he noticed the rain had stopped.
人物认知变化的叙事句型
本课的笑点来自“先以为自己快到站了，后来才发现坐过头”，所以 I thought... / I realized... 这类句型特别关键。
相似句：
- I thought it was the right road, but I was mistaken.
- Only then did I realize that I was the last passenger.
