这部分主要学习如何用 What's the matter? 询问和回答常见的健康问题，并学习 should 的基本用法。

对话场景: 通常是两个人在讨论身体状况，一方给出建议。
核心句型练习:
- A: What's the matter, Ben?
- B: I hurt myself playing soccer.
- A: You should see a doctor and get an X-ray.
- B: OK, I think I should.
- A: And you shouldn't run for a week.

这部分拓展了更多健康问题（如 have a nosebleed），并引入了 What should you do when you have a ...? 的句型来集中练习建议，通过一个关于“登山者”的故事，将 should 的用法融入到叙事中。

知识拓展:
- 流鼻血: have a nosebleed
- 建议:
  - Sit down and put your head back. (坐下，把头向后仰。) - 错误示范，现代医学建议向前倾。
  - Put your head down slightly. Pinch the soft part of your nose. (稍微低下头，捏住鼻子柔软的部分。)
  - Hold it for a few minutes. (坚持几分钟。)
阅读文章《山上的问题》:
- 故事梗概: Aron Ralston 在一次登山事故中被巨石压住手臂，无法脱身，他面临是等待死亡还是自己做出选择的艰难处境。
- 核心词汇: be in control of, get into trouble, give up, cut off his arm, spirit
- 主题: 探讨了在极端情况下，求生的勇气和自救的重要性。

区分 have a ... 和 ... hurts:
- I have a headache. (我有头痛。)
- My head hurts. (我的头疼。) 两者意思相近，但 have a + 身体部位 + ache 是更固定、更常见的搭配。
should 后面跟动词原形:
- 错误: You should to see a doctor.
- 正确: You should see a doctor. (should 本身就含有“应该”的意思，后面不能再加 to。)
反身代词的使用:
- 错误: He hurt him.
- 正确: He hurt himself. (伤的是他自己，所以用反身代词。)
牢记 have a + 病症 的搭配:
- have a cold (感冒), have a fever (发烧), have a cough (咳嗽), have a stomachache (胃痛) 等，这是固定的用法。
