(不要喝太多含糖饮料。) 【核心词组积累】 · look after 照顾 / 保护 (等同于 take care of) · green vegetables 绿叶蔬菜 (vegetable 为可数名词) · give ... a break 让……休息一下 · check your phone 检查/刷手机 · get enough sleep 获得充足的睡眠 (sleep 在此处作不可数名词) · at least twice a day 每天至少两次 (once 一次，twice 两次，三次及以上用 基数词 + times) · more than... 超过…… / 多于…… (等同于 over) · sweet drinks 含糖饮料 / 甜饮料 【核心句型精讲与真题演练】 📌 句型 1：表达健康建议的情态动词（should / shouldn't） 1/4 学科网（北京）股份有限公司 · 核心结构： · 肯定提议：主语 + should + 动词原形 (+ 其他). (应该/需要做某事) · 否定劝阻：主语 + shouldn't + 动词原形 (+ 其他). (不应该/不要做某事) · 💡 避坑提示： 期末必考常青树！ should 和 shouldn't 属于情态动词，用来提出合理的建议。牢记它们的金科玉律：后面紧跟动词原形。任凭主语是第三人称单数，动词也绝不能变形。 (1) 单项选择 ( ) 1. Your eyes are tired. You should ______ a break right now. A. gives B. give C. giving ( ) 2. Children ______ play computer games for too long. It's bad for their eyes. A. should B. shouldn't C. can 📌 句型 2：不可数名词与可数名词的修饰辨析（less / too many） · 核心结构： · 少吃/做……：Eat/Do + less + 不可数名词. · 太多……：too many + 可数名词复数 / too much + 不可数名词 · 💡 避坑提示： 文本中的 candy 被视作不可数名词，因此表示“少吃糖”必须用 less candy。而 drinks 是可数名词复数，因此表示“太多饮料”必须用 too many sweet drinks。真题里非常喜欢将 many 和 much、less 和 fewer 混在一起考查名词的数。 (1) 单项选择 ( ) 1. To look after your teeth, you should eat ______ candy. A. less B. many C. fewer ( ) 2. Don't eat ______ hamburgers. They are not healthy food. A. too much B. too many C. less 📌 句型 3：动名词作主语与频率表达（Eating fish is good...） · 核心结构： 动词-ing形式 (+ 宾语) + be动词(is) + 形容词. (做某事是……的) · 💡 避坑提示： 当我们想把一个动作（比如 eat fish）当作一句话的主语时，必须把动词变成 ing 形式（动名词）。例如课文原句：Eating fish is good too.。这时候，整件事情当作单数看待，后面的 be 动词必须用 is。 (1) 单项选择 ( ) 1. ______ sports every day is a good habit for our health. A. Play B. Plays C. Playing (2) 句型转换（每空一词） 2. I brush my teeth twice a day. (对划线部分提问) ______ ______do you brush your teeth? 【综合通关：阅读理解判断真题演练】 阅读短文，判断下列句子是否符合短文内容，符合的填 “T”，不符合的填 “F”。 How to have a healthy life? Here is some good advice for you.

B (根据常识和后句“这对他们的眼睛有害”可以推断，孩子们“不应该”长时间玩电脑游戏，故选 shouldn't) 📌 随堂真题演练 2： 1. A (candy 在本处作不可数名词，表示“少吃”用 less 修饰。fewer 只能用来修饰可数名词复数，故选 A) 2. B (hamburgers 是可数名词复数，表示“太多”时应该使用 too many。too much 只能用来修饰不可数名词) 📌 随堂真题演练 3： 1. C (空格处在句中作主语，应当使用动名词形式 Playing，表示“每天做运动”这一项行为习惯) 2. How often (对频率词 twice a day “一天两次”提问，疑问词固定使用表示频率的 How often 引导) 📌 综合通关（阅读判断）： 1. F (文章中明确指出 “Eating fish is good too”，说明吃鱼对眼睛有好处，而非有害) 2. F (短文提到 “We shouldn't check our phones or watch TV so often”，不应该频繁刷手机看电视，题干句意反了) 3. F (原文提到每次刷牙要 “for more than two minutes” 超过两分钟，题干中的 less than 意为少于，表述错误) 4. T (根据课文基础推断，建议吃像坚果这样的健康零食，少吃糖，说明坚果健康而糖果不健康，表述正确) 5. T (原文指出不应该喝太多甜味饮料 “Don't drink too many sweet drinks”，这能保护牙齿健康，表述完全符合题意) $
