This morning, I woke up at 9:00. Mom made porridge, but I was in a hurry to watch cartoons, so I just grabbed a handful of candies. Mom said it's not good to skip breakfast, but I didn't listen. At noon, we had a picnic with my family in the park. Dad made sandwiches with lettuce and chicken—those were yummy! But my cousin brought a big bag of potato chips, and I ate almost half of it. Mom said, “Lily, too many chips will make you thirsty.” She was right—I drank three cups of cola after that. In the afternoon, I felt a little sick. Grandma gave me an apple, and that made me feel better. For dinner, Grandma cooked my favorite: steamed fish, stir-fried cabbage, and white rice. I ate all the vegetables—Grandma said I grew taller! I think tomorrow I'll eat more healthily. 任务一：根据日记内容，在思维导图的分支中填写Lily周日的食物（每空1个短语）。 任务二（健康饮食周计划卡）： 设计一张“Healthy Weekly Plan”（选3天，如周二、周四、周六），用英语填写每天三餐的健康食物，并在计划卡底部写一句鼓励健康饮食的话（如 “Eat well, feel great!” ）。 Day Breakfast Lunch Dinner Slogan: 参考解析 基础练 一、词汇分类 Healthy: tomatoes, grapes, oats, carrots, juice Unhealthy: chips, biscuits, candies, burgers, cola 二、语音找朋友 ow 组（选填 4 个示例）：yellow, cow, window, crow 解析：这些单词里的 “ow” 字母组合发 /əʊ/ 音 。比如 yellow 中 “ow” 发 /əʊ/ ，和 slow 的 “ow” 发音一致 。 oa 组（选填 4 个示例）：goat, coat, boat, soap 解析：“goat（山羊）”“coat（外套）”“boat（船）”“soap（肥皂）” 里的 “oa” 都发 /əʊ/ 音 。 三、根据提示写句子 1. You shouldn't eat too much junk food. 解析：用shouldn't表达“不应该”，too much修饰不可数名词junk food。 1. We should eat fruit every day. 解析：用should表达“应该”，every day说明频率。 1. Sally eats dinner too quickly. She should eat slowly. 解析：前句描述问题（too quickly），后句用should提建议（slowly修饰eat）。 1. Just a few biscuits for breakfast are not enough. You should eat bread and milk. 解析：结合“a few biscuits不够健康”的语境，用should建议替换为bread and milk。 1. These candies are bad for your teeth. You shouldn't eat them. 解析：用be bad for说明危害，shouldn't否定“吃糖果”的行为。 提升练 四、用方框内词汇填空（每词限用一次）： 1. should; healthy 解析：“应该吃健康食物”，healthy修饰food。 1. too many; a few 解析：too many修饰可数名词biscuits（“太多饼干”）；a few表示“少量（足够）”。 1. should; slowly 解析：“应该慢慢吃晚餐”，slowly（副词）修饰eat。 1. junk; shouldn't 解析：cola和chips是junk food（垃圾食品）；shouldn't表示“不应该经常吃”。 五、单项选择 1. A 解析：should引导建议，否定回答用shouldn't，考查情态动词用法。 1. C 解析：tomatoes等属于healthy food（健康食物），对应chant中“Go”类食物的描述。 1. B 解析：never（从不）吃蔬菜，符合“胃不开心”的原因。 1. C 解析：否定祈使句以Don't开头，考查祈使句结构。 1. B 解析：because引导原因，回答why的提问。 六、句型转换 1. We shouldn't eat unhealthy food. （注：原句“should eat healthy food”的否定需逻辑调整，若题目为“should eat junk food”，则否定为“We shouldn't eat junk food.” 此处按“健康食物应吃，不健康不应吃”逻辑改写。） 解析：should的否定形式是shouldn't，后接动词原形。 1. Don't take too much junk food. 解析：祈使句否定在句首加Don't。 1. Sally eats dinner quickly because she wants to play. 解析：用because连接“吃得快”和“想玩”的因果关系。 1. How does the stomach feel? 解析：对“bad（感受）”提问，用how；主语stomach是第三人称单数，助动词用does。 1. The doctor says we should eat slowly. 解析：间接引语中，祈使句“Eat slowly”转换为“should + 动词原形”。 七、【新情境·健康咨询】补全对话 1. B 解析：询问“饮食有什么问题”，用What's wrong with... 1. E 解析：回答午餐内容“汉堡和可乐”，对应不健康饮食 1. C 解析：询问“是否吃早餐”，用Do you have... 1. D 解析：建议“别吃太多垃圾食品”，用Don't eat... 1. A 1. 解析：建议“晚餐也应慢慢吃”，用should eat slowly 拓展练 八、【新情境·新题型】日记阅读与健康计划设计 任务一（思维导图填写） · Morning: a handful of candies · Noon (Picnic): sandwiches with lettuce and chicken、potato chips、cola · Afternoon: an apple · Evening: steamed fish、stir-fried cabbage、white rice 任务二（健康饮食周计划卡示例） Day Breakfast Lunch Dinner Tuesday milk, whole-grain bread, pear brown rice, beef, broccoli noodles, eggs, tomatoes Thursday oatmeal, yogurt, banana pasta, chicken, spinach steamed pork, carrots, soup Saturday cereal, milk, orange rice, tofu, green beans grilled fish, lettuce, salad Slogan: “Healthy eating, happy every day!” 解析： 本题考查健康饮食的实践应用。计划卡需涵盖谷物（如whole-grain bread, rice）、优质蛋白（如beef, chicken）、蔬菜（如broccoli, carrots）和水果（如pear, banana），确保营养均衡。标语需贴合主题，简洁易记，呼应日记中Lily“想明天吃得更健康”的想法，强化“健康食物选择”的意识。 2 / 2 学科网（北京）股份有限公司 $$
