这个单元有 5 章：主题课文"一次被低估的流感"、词汇延展（看病流程词族 + 身心健康搭配）、语法延展（被动语态纵深——从一般被动到完成被动、情态被动、被动不定式）、功能句型（口语 Part 2 描述健康问题 + Writing Part 1 Essay 引例）、FCE 考点与 8 题自测。
学完你能：用 200+ 医疗词描述一次就医经历；在书面语里自如切换主被动，让句子显得客观专业；Writing Part 1 Essay 里能用"Studies have shown that... / It is believed that..."这类客观句式立论——这是 B2 写作拿高分的关键信号。
预计时间：1.5 周。被动语态是 B2 语法的"重炮"，也是中国学生最容易"用错"而非"不会"的一项——形式不难，难在"什么时候该用被动"。
级别提醒：FCE Reading & Use of English Part 4（key word transformations）每年必考一道被动改写；Writing Part 1 Essay 要求"客观学术语气"，被动语态就是它的外壳。
健康单元 = 就医词族 + 被动语态纵深 + Essay 客观句式。课文带你看一次从"扛着不去医院"到"被医生留观"的完整经历，词汇按"症状/诊疗/康复"三组展开，语法攻克 B2 写作最需要的"客观学术腔"。
主题课文 · 一次被低估的流感
课文 · A Flu I Shouldn't Have Ignored
课文精讲 · B2 健康阅读的三条暗线
论读 B2 健康类文章，别只盯单词
第一条暗线：时态。"I told myself / I kept going / I was dragged"——一般过去时讲主线；"I had been given / had been developing / had been ignoring"——过去完成进行时讲"更早发生的事"。Reading Part 5 完形最爱靠时态线索出题。
第二条暗线：被动。was examined / was prescribed / is considered / are given / was forced——全文被动贯穿。B2 健康类文章天然偏客观，被动就是它的语气。写作模仿时，把"我开了药"换成"药被开给我"，立刻学术感上来。
第三条暗线：科普常识。抗生素不治病毒、退烧药退不下才算高烧——这些是 Part 1 阅读里常见的"事实细节题"考点。B2 阅读不考偏门医学，但考你能不能读懂科普逻辑。
考试怎么考：FCE Reading Part 6 互文阅读常拿"健康/睡眠/饮食"四篇短文匹配观点；Part 4 改写每年至少一道 "they gave me antibiotics" ↔ "I was given antibiotics"。
① prescribe medicine 开药（被动：be prescribed）
② run a fever / have a temperature 发烧
③ bring a fever down 退烧
④ recover from 从…康复（recover from a cold）
⑤ be diagnosed with 被诊断为…（B2 高频）
词汇延展 · 就医与身心健康词族
四组就医词族
（可参看「健康就医词族」深化页）| 组 | 核心词块 | 搭配/备注 |
|---|---|---|
| 症状 | sore throat, runny nose, cough, fever, headache, stomach ache, dizzy, exhausted, nauseous, rash | have a headache / feel dizzy（feel + adj） |
| 诊疗 | make an appointment, check-up, examine, prescribe, prescription, diagnosis, blood test, X-ray, surgery, ward | make an appointment with the doctor |
| 康复 | recover from, get over, make a full recovery, rest up, discharge from hospital, side effect, vaccine | get over a cold = 熬过感冒 |
| 心理健康 | wellbeing, stressed out, burn out, anxiety, depressed, cope with, relax, mindfulness, work-life balance | burn out / burnout 过劳 |
词形转换 · Part 3 必练
| 动词 | 名词 | 形容词 | 副词 |
|---|---|---|---|
| treat | treatment | — | — |
| recover | recovery | recovered | — |
| diagnose | diagnosis | diagnostic | — |
| prescribe | prescription | — | — |
| anxious | anxiety | anxious | anxiously |
| depress | depression | depressed / depressing | — |
① depressed vs depressing：人用 depressed（I feel depressed），事用 depressing（The news is depressing）。Part 3 必考。
② 看病搭配：see a doctor（不是 see doctor）；make an appointment（元音前 an）。
③ recover 是不及物：recover from a fever（不能说 recover a fever，那是"找回"）。
④ health vs healthy：physical health（名词）；a healthy diet（形容词）。Part 3 常考 health → healthy。
⑤ 发烧说法：英式 have a temperature / have a fever 都对；美式更爱 fever。说"高烧"是 a high temperature，不说 a high fever（虽然能懂，但剑桥偏好 temperature）。
语法延展 · 被动语态纵深
被动语态全时态表
（可参看「被动语态」深化页）| 时态 | 主动 | 被动 |
|---|---|---|
| 一般现在 | Doctors prescribe antibiotics. | Antibiotics are prescribed. |
| 一般过去 | The doctor examined me. | I was examined. |
| 现在进行 | They are building a new hospital. | A new hospital is being built. |
| 过去进行 | She was treating a patient. | A patient was being treated. |
| 现在完成 | They have tested the vaccine. | The vaccine has been tested. |
| 过去完成 | I had ignored the symptoms. | The symptoms had been ignored. |
| 将来 | They will discharge him tomorrow. | He will be discharged tomorrow. |
| 情态动词 | You must take this twice a day. | This must be taken twice a day. |
B2 被动的四种高级用法
| 用法 | 结构 | 例子 |
|---|---|---|
| It is said/believed that... | It + be + 过去分词 + that 从句 | It is believed that stress causes many illnesses. |
| sb is said/believed to do | sb + be + 过去分词 + to 不定式 | He is known to be an expert. |
| 被动不定式 | to be done / to have been done | The meeting is to be held next week. |
| get + 过去分词（口语被动） | get done | I got treated at the clinic.（口语，比 be treated 更随意） |
什么时候用被动？——B2 最容易丢分的判断
论不是所有句子都要被动
① 不知道动作发出者时：My bike was stolen.（不知道谁偷的）
② 动作发出者不重要时：The new hospital was opened last year.（谁开的不重要）
③ 想强调承受者时：Antibiotics are prescribed only for bacterial infections.（强调抗生素）
④ 学术/客观语气：It is believed that... / It has been shown that...——Essay 里用这些避免"I think"。
什么时候别用被动：口语 Part 2 讲自己的故事，主动更自然；全是被动会显得像机器人。B2 评分看"主被动切换自然"。
① "They gave me antibiotics" 改写：I was given antibiotics.（双宾语被动：把间接宾语 I 提前）
② "People say that he is rich" 改写：He is said to be rich.（It is said that = sb is said to）
③ 完成被动别漏 been：The report has been written（不是 has written）。
④ 进行被动别漏 being：The house is being built（不是 is built）。
⑤ 不及物动词没有被动：happen / appear / disappear 不能用被动。The accident was happened 是错的。

下一单元预告 · Science & Technology
论从健康到科技，B2 语法怎么接力
语法接力：本单元专攻被动；Unit 7 把被动和完成时态、进行时态揉在一起考——"现在完成进行被动""将来完成时"这种复杂时态综合，是 B2 阅读里学术文章的标配。
词汇接力：健康词族讲完，Unit 7 进入科技词族（innovation / breakthrough / device / algorithm / artificial intelligence），同样按"研发/使用/争议"分组。
现在就做：把本单元课文里的被动句全部圈出来，盖住英文自己回译主动句——主被动互译是 Part 4 的核心训练。
