交通工具:
- subway / underground (地铁)
- train (火车)
- bus (公共汽车)

这些句型是进行旅行对话和写作的骨架。

问: How long does it take? / How long does it take to get to... by...?
(这需要多长时间？/ 坐...去...需要多长时间？)
答:
- It takes (about) 40 minutes.
  (大约需要40分钟。)
- It takes (me) 10 minutes to walk to the park.
  (我步行到公园需要10分钟。)

问: Where would you like to go? / What are you doing for vacation?
(你想去哪里？/ 你假期打算做什么？)
答:
- I'd like to go to Hainan. / I'm going to Beijing.
  (我想去海南。/ 我打算去北京。)
- I hope to visit the Great Wall.
  (我希望去参观长城。)
- That sounds interesting / relaxing / exciting.
  (听起来很有趣/很放松/很刺激。)

这是本单元最重要的语法点,当表示已经安排好、有确定计划的将来动作时，特别是表示位置移动的动词（如 go, come, leave, arrive, fly, travel 等），可以使用现在进行时。

结构: am / is / are + 动词-ing
例句:
- I am leaving for Shanghai tomorrow.
  (我明天动身去上海。)
- They are flying to Hong Kong next week.
  (他们下周要飞往香港。)
- He is coming to visit us this afternoon.
  (他今天下午要来看我们。)
对比:
- I go to school every day. (我每天都去学校。 - 习惯性动作)
- I am going to the cinema tonight. (我今晚要去看电影。 - 今晚的计划)

本单元集中学习了 how 的多种用法，用来提问不同信息。

How do you...? (询问方式)
- How do you get to school? (你怎么去学校？)
How far...? (询问距离)
- How far is it from here? (从这里有多远？)
How long...? (询问时间长度或物体长度)
- How long does it take? (需要多长时间？)
- How long is the river? (这条河有多长？)
How often...? (询问频率 - 虽然常在第二单元出现，但也是 how 的重要用法)
- How often do you exercise? (你多久锻炼一次？)

掌握了以上知识点,你就可以进行以下场景的对话和写作了：

问路与指路:
- "Excuse me, is there a post office near here?" (打扰一下，这附近有邮局吗？)
- "Yes, it's across from the bank." (有的，它在银行对面。)
- "How can I get there?" (我怎么去那里？)
- "You can take the No. 5 bus and get off at the third stop." (你可以坐5路公交车，在第三站下车。)
制定旅行计划:
