易错点一：情态动词should/shouldn't提建议 & advice不可数属性
should/shouldn't后接动词原形，用于提建议；advice（建议）是不可数名词，无复数形式，常用a piece of advice表示“一条建议”，学生常错误加s或搭配不当。
易错题1
You have a cold. You ______ drink more hot water and have a good rest.
A. should B. shouldn't C. shoulds D. to should
易错题2
My teacher gave me some useful ______ on how to stay healthy.
A. advice B. advices C. an advice D. a advices
易错点二：too much / too many / much too 辨析
三者在健康场景中出现频率极高，学生常混淆修饰对象：
• too much：修饰不可数名词，如too much junk food
• too many：修饰可数名词复数，如too many hamburgers
• much too：修饰形容词/副词，表“实在太……”，如much too tired
易错题3
Eating ______ junk food is bad for your stomach. You should eat more vegetables.
A. too many B. too much C. much too D. many too
易错题4
After staying up late playing games, I felt ______ tired to go to school this morning.
A. too much B. too many C. much too D. so many
易错点三：maybe 与 may be 混淆
• maybe：副词，意为“也许”，放句首作状语，相当于perhaps
• may be：情态动词may + be动词，意为“也许是”，放主语后作谓语
学生常将二者混用，错误表达为Maybe he is ill写成May be he is ill。
易错题5
______ you have a fever. You should take your temperature.
A. May be B. Maybe C. May D. Be

易错点四：疾病类固定搭配
单元核心疾病搭配是学生易错重灾区，需严格记忆：
• 患病用have a + 疾病：have a cold/fever/cough/stomachache
• 看医生用see a doctor/go to the doctor's，不能用go to the doctor
• 牙疼用have a toothache，不能说have toothache

易错点六：-ed / -ing 形容词辨析
延续Unit1的情绪类形容词辨析，结合健康场景强化记忆：
• -ed形容词：修饰人，表“感到……的”，如tired/excited/stressed
• -ing形容词：修饰事物/活动，表“令人……的”，如tiring/exciting/stressful

易错点七：lie 的多含义及变形辨析
