Unit 2 School rules（期中知识清单）四年级英语上学期（冀教版三起·新教材）

知识清单·冀教版四年级上册 Unit 2 School rules 知识梳理 知识点拨 【考点一】谈论规则的 “should/shouldn't” 句型 【考点二】否定祈使句（标识类） 【考点三】学校场景与规则匹配 考点一：谈论规则的 “should/shouldn't” 句型 In the canteen,we should wait in line.(在食堂，我们应该排队。） 解析：考查 “场景 + 规则” 的对应能力，需要明确不同地点（图书馆、教室、食堂等）的专属规则，避免混淆。 （一）核心结构： 1.肯定（应该做）：主语 + should + 动词原形 + 其他 2.否定（不应该做）：主语 + shouldn't + 动词原形 + 其他 （注：should/shouldn't 后永远跟动词原形，如 “should stand”“shouldn't eat”，不能加 s/es） （二）场景应用： 场景 肯定句（应该做） 否定句（不应该做） 图书馆 We should be quiet. We shouldn't eat. 教室 We should listen to teachers. We shouldn't run or jump. 食堂 We should wait in line. We shouldn't push. 【记忆口诀】 规则用 should，应该做的原形上；否定 shouldn't 加，不做的事也原形抓。 【大显身手】 一、单项选择题。 （ ）1.We ______ be quiet in the library. A. should B. shouldn't C. can't D. are （ ）2.______ run in the classroom! It's dangerous. A. Not B. Don't C. Doesn't D. Isn't （ ）3. In the canteen, we ______ wait in line. We ______ push others. A. should; shouldn't B. shouldn't; should C. can; can't D. are; aren't （ ）4.—Look at the sign! What does it mean? —It means “______ the grass”. A. Walk on B. Keep off C. Litter on D. Run on （ ）5.We should ______ to school on time every day. A. get B. gets C. getting D. got 考点二：否定祈使句（标识类） Don't litter！（不要乱扔垃圾！）；Don't run！（不要跑！） 学校标识常用 “否定祈使句” 提醒禁止行为，结构简单、语气明确，是日常交际和规则传达的重点。 （一）核心结构：Don't + 动词原形 + 其他 （注：开头 “D” 大写，句末用感叹号；动词必须用原形，如 “Don't litter” 不能说 “Dont litters”） （二）常见标识对应句型： 1.不践踏草地：Don't walk on the grass! 2.不喧哗：Don't be noisy! 3.不在书上写字：Don't write in the book! 【记忆口诀】 标识禁止用 Don't，动词原形紧跟后；大写开头叹号尾，规则提醒记心扉。 【大显身手】 1、 判断题（对打 “√”，错打 “×”） 1.We shouldn't be quiet in the library.（ ） 2.Don't write in the book! It's a rule.（ ） 3.In the classroom, we should run to be fast.（ ） 4.We should stand in line in the canteen.（ ） 5.“Keep off the grass” means we can walk on the grass.（ ） 考点三：学校场景与规则匹配 In the canteen, we should wait in line.（在食堂，我们应该排队。） 解析：考查 “场景 + 规则” 的对应能力，需要明确不同地点（图书馆、教室、食堂等）的专属规则，避免混淆。 高频场景与规则对应表： 学校场景 关键规则（should/shouldn't） Library should be quiet/stand in line；shouldn't eat/write in books Classroom should listen to teachers/keep clean；shouldn't run/jump Canteen should wait in line/eat up food；shouldn't push/litter Playground should walk on the right；shouldn't walk on the grass 【记忆口诀】 图书馆静不吃喝，教室听讲不跑跳；食堂排队不推挤，操场靠右不踩草。 【大显身手】 一、仿写句子（结合学校场景）。 1.用 “should” 仿写（图书馆场景）：_____________________________________________ 2.用 “shouldn't” 仿写（教室场景）：_____________________________________________ 3.用 “Don’t...” 仿写（操场标识）：_______________________________________________ 写作指引 一、写作。 请以 “My School Rules” 为题，写一篇英语短文，介绍你学校的 2-3 条规则，说明规则对应的场景和遵守规则的原因。要求：句子通顺，不少于 40 词。 （一）写作指导（分 3 步，可直接套用） 第一步：梳理思路：确定 2-3 个学校场景（如图书馆、食堂），对应每条场景的规则。 第二步：拆解写作结构（分 “开头 - 中间 - 结尾”，每部分写 1-2 句） 1.开头：总述 “学校有很多规则”； 2.中间：分述 1-2 条规则（场景 + should/shouldn't 句型）； 3.结尾：说明遵守规则的好处（如 “keep safe”“make school tidy”）。 第三步：必用核心句型 写作时优先用这些前单元学过的句型，既符合要求又不易出错： 1.We have many school rules. 2.In the ..., we should ... 3.We shouldn't ... because ... 4.Following rules helps us ... （二）范文： My School Rules We have many good rules at my school. In the library, we should be quiet. We shouldn't eat or drink there. It helps others read well. In the canteen, we should wait in line. We shouldn't push. It keeps us safe. I like following school rules. They make our school tidy and happy. 综合训练 一、单项选择题 （ ）1. We ______ quiet in the library yesterday.
