内容正文:

知识清单·北京版四年级上册 Unit3 Be a Nice Person 知识梳理 知识点拨 【考点一】礼貌请求句型(委婉表达) 【考点二】提建议 / 表义务的句型 【考点三】疑问词 + 不定式的结构 考点一:礼貌请求句型(委婉表达) 1. —Would you do me a favour , please? —Sure, Mike. 解析:这句话是极委婉的礼貌请求句型,用于向他人客气地寻求帮助,核心是 “请求帮忙” 的固定表达。 (1)结构:Would you + 动词原形 + 其他 + , please? (2)固定短语:“do me a favour”,“帮某人一个忙”,是日常交际中请求帮助的常用短语。 (3)易错点提醒 “do” 必须用原形:因为 “Would you” 后接动词原形,不能写成 “Would you does...?”; “me” 不能换成 “I”:“do” 是动词,后面要接宾格,“I” 是主格,只能作主语,不能作宾语; “favour” 是固定搭配:不能说成 “do me a help”,“do sb a favour” 是固定短语,记住即可。 2. —May I use your bat? —Sure. Here you are. 解析:这组对话是礼貌请求许可 + 肯定回应的典型交际场景,用于 “向他人借物品(球拍)”,前一句是请求,后一句是同意并递物 (1)结构:May I + 动词原形 + 其他? (2)作用:是非常礼貌的请求许可句型,意为 “我可以…… 吗?”,比 “Can I...?” 语气更正式、更客气,适合向他人借东西、请求做某事时使用。 (3)适用场景:同学之间、朋友之间借物品(如球拍、文具、书籍等)时的对话。 比如:体育课上想借同学的乒乓球拍,就可以说 “May I use your bat?”,对方同意后递球拍时说 “Sure. Here you are.”。 (4)易错点提醒 “May I” 后接动词原形:不能写成 “May I using your bat?” 或 “May I uses your bat?”; “Here you are.” 语序固定:不能调换为 “Here are you.”,否则意思错误; “bat” 的语境理解:结合 “借物品” 场景,优先理解为 “球拍”,而非 “蝙蝠”(避免语义混淆)。 3. —Could you sweep the floor please, Baobao? —Sure. 解析:这组对话是委婉请求帮忙 + 简洁肯定回应的日常交际场景,用于 “礼貌请宝宝扫地” 并得到同意,前一句聚焦 “请求对方做事”,后一句聚焦 “回应请求” (1)结构:Could you + 动词原形 + 其他 + , please? + 称呼? (2)作用:是 Can you...? 的委婉形式,意为 “你能…… 吗?”,语气比 Can you...? 更客气,适合请他人帮忙做具体事情(如扫地、递东西等)。 (3)适用场景:熟悉的人之间请帮忙做家务或小事,比如: 妈妈请宝宝扫地:“Could you sweep the floor please, Baobao?” → 宝宝回应:“Sure.” 同学请你帮忙递尺子:“Could you pass me the ruler please?” → 你回应:“Sure.” (4)易错点提醒 “Could you” 后接动词原形:不能写成 “Could you sweeping the floor...?”(“sweeping” 是现在分词,错误); “sweep the floor” 不能漏 “the”:“floor” 是特指 “当前的地板”,必须加定冠词 “the”,否则语法错误; “Could” 不表 “过去”:这里 “Could you” 不是 “can you” 的过去式,而是专门表 “委婉请求”,不用纠结时态,记住 “请求用 Could you + 原形” 即可。 【大显身手】 一、单项选择题。 ( )1. —______ do me a favour, please? —Sure. What do you need? A. Would you B. Will you C. Do you ( )2.—May I use your bat? —______ A. Sorry, I can’t. B. Sure. Here you are. C. No, I don’t. ( )3.—Could you ______ please? The floor is dirty. —Of course! A. sweep floor B. sweep the floor C. sweeping the floor ( )4.—Could you ______ the floor please, Baobao? —Sure. I’ll do it now. A. sweeps B. sweeping C. sweep ( )5.If you want to ask your friend to help you carry books, you can say: ______ A. May I carry the books? B. Would you do me a favour, please? C. Do you carry the books? 考点二:提建议 / 表义务的句型 We should stand in line and get on one by one. 解析:这句话是提建议 / 表规则的典型表达,用于告诉他人 “应该排队、依次上车”,核心涵盖 “情态动词 should 的用法”“并列结构” 和 “固定短语”。 (一)核心语法:情态动词 should 表 “应该” 1.结构:主语 + should + 动词原形 + 其他 2.作用:should 是情态动词,没有人称变化(无论主语是 I/we/you/he/she,都用 should),意为 “应该”,用于提出合理建议、说明规则或义务(比如遵守公共秩序、养成好习惯)。 3.本句应用:We should...(我们应该……),明确建议 “我们要遵守排队上车的规则”,语气友好且有指导性,不生硬。 (二)并列结构:and 连接两个动词原形 1.结构:should + 动词原形1(stand) + and + 动词原形2(get on) 2.解析:句中用and(和)连接两个并列的动作 ——“stand in line”(排队)和 “get on”(上车),因为两个动作都受情态动词should修饰,所以两个动词都必须用原形,不能说 “should stands” 或 “should getting on”。 示例对比: ✅ 正确:We should read and write.(我们应该读和写。) ❌ 错误:We should reads and writing. (三)必记固定短语(结合生活场景) 1.stand in line 含义:排队(指按顺序排成一列,不插队)。 生活场景:买文具时、上公交车时、操场集合时,都可以说 “stand in line”。 例句:We should stand in line at the supermarket.(我们在超市应该排队。) 2.get on 含义:上车(特指上公交车、大巴车、火车等大型交通工具;上小汽车用 “get in”)。 搭配:get on + 交通工具(如 get on the bus 上公交车,get on the train 上火车)。 3.one by one 含义:一个接一个地(强调 “依次、不拥挤”,常用来补充说明 “怎么做”)。 用法:通常放在句末,修饰动作。 例句:The students go into the classroom one by one.(学生们一个接一个走进教室。) (四)整句意思与使用场景 1.完整句意:“我们应该排队,一个接一个地上车。” 2.使用场景:常用于提醒他人遵守公共秩序,比如: 老师对学生说:“When we take the school bus, we should stand in line and get on one by one.”(我们坐校车时,应该排队,一个接一个上车。) 家长对孩子说:“At the bus stop, we should stand in line and get on one by one.”(在公交站,我们应该排队,一个接一个上车。) (五)易错点提醒 1.should 后面必须接动词原形,不能加 “s” 或 “ing”(如不能说 “We should stands...”)。 2.“上车” 的表达:上公交车 / 火车用 “get on”,上小汽车用 “get in”,不要混淆。 3.“one by one” 是固定搭配,不能改成 “one and one” 或 “one by two”。 【大显身手】 1、 单项选择 ( )1. We should ______ in line when we wait for the bus. A. stand B. stands C. standing ( )2.—What does “get on” mean in “get on the bus”? —It means “______”. A. 下车 B. 上车(公交 / 火车等) C. 上车(小汽车) ( )3.The students go into the classroom ______ before class. A. one and one B. one by one C. one to one ( )4.We should ______ and ______ quietly in the library. A. read; write B. reads; writes C. reading; writing ( )5.The sentence “We should stand in line and get on one by one.” is often used ______. A. at the bus stop(公交站) B. in the bedroom(卧室) C. at the dining table(餐桌旁) 考点三:疑问词 + 不定式的结构 Would you please tell me where to find some food? 解析:这句话是礼貌请求 + 疑问词 + 不定式结构的典型表达,用于委婉询问 “找食物的地点”。 (1) 核心句型:礼貌请求 “Would you please...?” 1.结构:Would you please + 动词原形 + 其他? 2.作用:是极委婉的请求句型,比 “Will you...?” 更礼貌,意为 “请你…… 好吗?”。 3.示例:本句中 “Would you please tell...?” 表示 “请你告诉我…… 好吗?”。 (二)双宾语结构:“tell me sth” 1.结构:tell + 间接宾语(人) + 直接宾语(事) 2.解析:“tell” 是及物动词,需接 “双宾语”—— 3.间接宾语:me(“我”,指人,用宾格); 4.直接宾语:where to find some food(“去哪里找食物”,指要告诉的内容)。 (三)“疑问词 + 动词不定式” 结构 1.结构:where + to find + some food 2.作用:相当于宾语从句(可替换为where I can find some food),用 “疑问词 + 不定式” 能让句子更简洁,表达 “做某事的地点 / 方式 / 时间”。 3.解析: 疑问词where:表 “在哪里”,询问地点; 不定式to find:“find”(找)用动词不定式形式,跟在疑问词后; 宾语some food:“find” 的对象,指 “一些食物”。 (四)整句意思与场景 1.句意:“请你告诉我去哪里找一些食物好吗?” 2.场景:向他人礼貌询问 “找食物的地点” 时使用(比如迷路找食物、游戏中找道具等场景)。 (五)拓展学习(同类结构) 询问 “做什么”:what to do(如:Could you tell me what to buy? 你能告诉我买什么吗?) 询问 “怎么做”:how to do it(如:Please show me how to draw a cat. 请给我展示怎么画猫。) 【大显身手】 ( )1. —______ tell me where to find some food? —Sure. A. Will you B. Would you please C. Do you ( )2. “Would you please tell me where to find some food?” Here, “me” is a ______. A. subject(主语) B. direct object(直接宾语) C. indirect object(间接宾语) ( )3. Which part is “疑问词 + 不定式” structure in “Would you please tell me where to find some food”? A. Would you please B. tell me C. where to find some food ( )4. You can replace “where to find some food” with ______. A.where I can find some food B. where find some food C. where can I find some food ( )5.—Would you please ______ me how to make a cake? —Of course. A. telling B. tell C. tells 写作指引 一、写作。 Write a short passage about your ways be a Nice Person in Daily Life. It should fit the unit theme "Be a Nice Person", include 5-6 sentences.
