这个单元有 5 章：主题课文"我的梦想职业"、词汇延展（职业词族）、语法延展（must 与 have to）、功能句型（聊梦想与规划）、KET 考点与自测。
学完你能：用 70+ 职业词汇聊工作、梦想和规划；must/have to 表达"必须/不得不"，区分"建议"和"必须"。
预计时间：1 周。
前后衔接：上接 Unit 10 家乡，下接 Unit 12 科技——"职业"是 KET 口语 Part 1（What do you want to be?）和阅读人物匹配的场景。
职业单元 = 职业词族 + must/have to + 梦想规划句型。课文带你看 Emily 和朋友的职业梦想，词汇按"职业/工作场所/规划"分组，语法攻克"必须做的事"。
主题课文 · 我的梦想职业
课文 · What Do You Want to Be?
课文精讲 · must vs have to
论一个"主观必须"，一个"客观不得不"
must = 主观义务/说话人要求："You must study hard"——妈妈的要求（主观）。
have to = 客观规定/外部需要："You have to pass many exams"——考试的客观要求；"Dad has to drive to the office"——客观需要。
时间上的区别：must 没有过去式（过去用 had to）；mustn't 表"禁止"（千万别），don't have to 表"不必"（不需要）。
考试怎么考：KET 完形：mustn't（禁止）vs don't have to（不必）——这两个是最常考的一对。
① grow up 长大（want to be when I grow up）
② want to be 想成为（职业：I want to be a doctor）
③ study hard 努力学习（hard 是副词）
④ pass an exam 通过考试（pass 及格 / fail 不及格）
⑤ do my best 尽我最大努力
三组词族 · 职业、工作、规划
| 组 | 核心词 | 搭配/备注 |
|---|---|---|
| 常见职业 | doctor, nurse, teacher, pilot, vet, engineer, driver, cook, shop assistant, police officer, postman, dentist | a/an + 职业（I'm a student） |
| 工作动作 | work, help, teach, drive, cook, look after, save, build, repair | work as（作为…工作）/ work for（为…工作） |
| 工作场所 | office, hospital, school, shop, airport, factory, police station | work in a hospital / at a school |
| 规划词 | future, dream, plan, grow up, study, pass, exam, university, job | in the future（将来）；go to university |
① 职业前要有 a/an：My mum is a doctor（不是 My mum is doctor）。但"成为"用 become：I want to become a teacher。
② work as / work for：work as a nurse（作为护士工作）；work for a company（为一家公司工作）。
③ job 和 work：job 可数（three jobs）；work 不可数（a lot of work）。"我有很多工作"说 I have a lot of work，不说 many works。
