Unit 1 People at work（期中知识清单）英语外研版三起四年级下册（新教材）

知识清单·外研版三起四年级下册 Unit1 People at work 知识梳理 知识点拨 【考点一】What does he/she do?第三人称单数特殊疑问句及回答 【考点二】Is he/she a...?第三人称单数一般疑问句及回答 【考点三】一般现在时第三人称单数动词变化 【考点四】职业名词与工作地点的搭配 考点一：What does he/she do?第三人称单数特殊疑问句及回答 A: What does he do? B: He's a scientist. 解析 问句：特殊疑问句，用于询问第三人称单数（he/she/单数人名）的职业。 a.疑问词What：意为“什么”，引导职业询问； b.助动词 does：因主语是第三人称单数，且谓语动词 do 是实义动词，需用助动词 does 构成疑问，动词 do 用原形； c.主语 he/she：指代第三人称单数的人。 答句：He/She is a(n) + 职业名词，He's = He is，She's = She is，说明职业身份。 易错点：主语是第三人称单数时，问句必须用 does，不能用 do；职业名词前要加 a/an（元音音素开头用 an，如 an ostrich，辅音音素开头用 a，如 a teacher）。 【大显身手】 ( )1.—What ______ she do? —She's a nurse. A. do B. does C. is ( )2.What does your father ______? A. do B. does C. is 3.填空 —What does he do? —He's a ______ (science). 4.句型转换 He is a cook.（对划线部分提问） ______ ______ he ______? 考点二：第三人称单数一般疑问句 Is he/she a...? 及回答 A: Is he a farmer? B: No, he isn't. He's a scientist. 解析 问句：一般疑问句，结构为 Is he/she a(n) + 职业名词?，用于确认第三人称单数的职业。 语调：读升调（↗）； 回答：肯定回答 Yes, he/she is.，否定回答 No, he/she isn't.，否定回答可补充正确职业。 易错点：问句中 Is 不能换成 Does；否定回答缩写为 isn't，不能写成 isnt。 【大显身手】 ( )1.—Is she a teacher? —______. She's a writer. A. Yes B. No C. OK ( )2—Is he a police officer? —______. He keeps the city safe. A. Yes B. No C. Hi 3.填空 —Is he a ______ (farm)? —No, he isn't. 4.句型转换 She is a doctor.（改为一般疑问句） ______ ______ a doctor? 考点三：一般现在时第三人称单数动词变化 He works hard. She helps people. He brings letters to people. 解析 一般现在时中，主语是第三人称单数（he/she/it/单数人名/单数事物）时，谓语动词要变化： a.一般动词：直接加 -s，如 work → works，help → helps； b.以 s/x/ch/sh/o 结尾的动词：加 -es，如 go → goes，watch → watches； c.以辅音字母 + y 结尾的动词：变 y 为 i 再加 -es，如 study → studies。 易错点：动词变化后，不能再用助动词 does 同时修饰（如 He works hard. 正确，He does works hard. 错误）。 【大显身手】 ( )1.He ______ in a school. A. work B. works C. working ( )2.My uncle ______ (bring) letters to people. A. bring B. brings C. bringing 3.填空 She ______ (help) people at night. 4.句型转换 They work at night.（改为单数句，主语为 he） He ______ at night. 考点四：职业名词与工作地点的搭配 A teacher works in a school. A doctor works in a hospital. A farmer works on a farm. 解析 常见职业与地点搭配： teacher — school（学校） doctor/nurse — hospital（医院） farmer — farm（农场） driver — bus/taxi（公交车/出租车） cook — restaurant（餐馆） police officer/fireman — police station/fire station（警察局/消防站） 易错点：介词搭配：work in a school/hospital，work on a farm，work at night。 【大显身手】 ( )1.A doctor works ______ a hospital. A. in B. on C. at ( )2.A teacher works ______ a school. A. in B. on C. at 3.填空 A farmer works ______ a farm. 4.句型转换 A cook works in a restaurant.（对划线部分提问） ______ ______ a cook work? 写作指引 My Dream Job 写作指导及范文 一、写作 请以 “My Dream Job” 为题，写一篇英语短文，描述你自己的理想职业，需包含：你想成为的职业、工作地点、工作内容、职业意义。要求：1. 句子通顺，思路清晰有条理。2. 不少于 40 字。 （一）写作指导（分 3 步，可直接套用） 第一步：梳理写作思路（先想 “3 个关键信息”） 关键部分 思考方向（举例） 1. 开头：点明主题 最喜欢的职业是什么，即自己想成为什么 2. 中间：具体介绍 想在什么地方工作、做什么工作、如何帮助他人 3. 结尾：总结感受 对这份职业的看法、自己的决心 第二步：拆解写作结构（分 “开头 - 中间 - 结尾”，每部分写 1-2 句） 开头：用核心句型引出自己的理想职业，1 句即可； 中间：介绍工作地点和具体工作内容，1-2 句； 结尾：表达对这份职业的喜爱和自己的决心，1 句即可。 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： I want to be a(n)... 我想成为一名…… He/She is a(n)... 他/她是一名……（可用于举例或补充） What does he/she do? 他/她是做什么工作的？（可用于举例） I will work in/on... 我将在……工作（拓展句型） I want to help people. 我想帮助人们。 （二）范文： My Dream Job I want to be a doctor.
