知识清单·精通版三年级上册 Unit4 Friends 知识梳理 知识点拨 【考点一】形容词性物主代词 【考点二】介绍某人的外貌的表达 考点一:形容词性物主代词 This is his nose. Her name is Lisa. 解析:这两个句子均为 主系表结构,核心语法重点是 形容词性物主代词 his/her 的用法 :修饰名词、表 “某人的” 所属关系,his 指代男性 “他的”,her 指代女性 “她的”。 (一)结构拆解:主系表结构 = 主语 + 系动词 + 表语 1.句子 1:This is his nose.(这是他的鼻子。) (1)主语:This(指示代词,“这、这个”,指代近处的单数事物) (2)系动词:is(be 动词的单数形式,连接主语和表语) (3)表语:his nose(“他的鼻子”,名词短语作表语,说明主语的归属) (4)his(形容词性物主代词,“他的”,修饰名词 nose,表 “属于他的”) (5)nose(名词,“鼻子”,单数形式,被 his 修饰) 2.句子 2:Her name is Lisa.(她的名字叫莉萨。) (1)主语:Her name(“她的名字”,名词短语作主语) (2)her(形容词性物主代词,“她的”,修饰名词 name,表 “属于她的”) (3)name(名词,“名字”,单数形式,被 her 修饰) (4)系动词:is(be 动词的单数形式) (5)表语:Lisa(人名,“莉萨”,说明主语 “名字” 的具体内容) (二)核心语法点:his/her 的用法(三年级重点掌握) 1.词性:形容词性物主代词(“形容词性” 说明必须修饰名词,不能单独使用) 2.核心功能:表 “所属关系”,即 “某人的”,后接名词构成名词短语。 3.指代对象与用法规则: (1)his:指代男性(he 的物主形式),后接名词,表 “他的……” 例句:his pen(他的钢笔)、his book(他的书) (2)her:指代女性(she 的物主形式),后接名词,表 “她的……” 例句:her ruler(她的尺子)、her bag(她的书包) (3)关键规则:his/her 必须放在名词前面,不能单独说 “his is nose”(错误),要加名词 “his nose”(正确)。 (三)简单搭配示例(贴合三年级词汇): (1)his + 身体部位:his eye(他的眼睛)、his ear(他的耳朵) (2)her + 物品 / 信息:her pencil(她的铅笔)、her age(她的年龄) (四)易混点区分(三年级必记) 1.区分 his/her 与 he/she(避免混淆人称代词和物主代词): (1)he(他)、she(她):人称代词,作主语,后面接系动词或实义动词(如 He is Tom. 他是汤姆。She likes cats. 她喜欢猫。) (2)his(他的)、her(她的):物主代词,作定语,后面必须接名词(如 his bag 他的书包、her desk 她的书桌) (五)注意事项 1.his/her 后面必须跟名词,不能单独使用(如 “这是她的” 要说 “This is her book”,不能说 “This is her”)。 2.选择 his 还是 her,要看指代的人是男性还是女性(指代男孩用 his,指代女孩用 her)。 3.句子中 be 动词用 is,因为主语都是单数(this、her name)。 【大显身手】 一、单项选择题。 ( )1. This is ______ book. He likes reading it. A. he B. his C. him D. she ( )2. ______ name is Lily. She is my classmate. A. Her B. She C. him D. his ( )3. Look! That is ______ pen. It’s red. A. she B. him C. his D. he ( )4. ______ mother is a teacher. We all like her. A. Him B. Her C. He D. she ( )5.—What’s ______ name? —He is Tom. A. her B. she C. his D. him 考点二:介绍某人的外貌的表达 This is his hair. And this is his mouth. 解析:这两个句子是 介绍某人外貌的基础主系表句型,核心结构为 “This is + 物主代词 + 身体部位名词”,用于清晰描述男性的外貌特征(头发、嘴巴),句子含义为 “这是他的头发。并且这是他的嘴巴。” (一)核心语法点:介绍外貌的基础句型(三年级重点掌握) 1.核心句型结构(必背): (1)单数身体部位:This is + 物主代词(his/her/my/your) + 身体部位名词(单数 / 不可数) 例句:This is her eye.(这是她的眼睛。)、This is my nose.(这是我的鼻子。) (2)复数身体部位:These are + 物主代词 + 身体部位名词(复数) 例句:These are his ears.(这是他的耳朵。)、These are your hands.(这是你的手。) 2.物主代词与指代对象的匹配(外貌描述关键): (1)描述男性外貌:用 his(他的)+ 身体部位(如 hair、mouth、eye) 例句:This is his face.(这是他的脸。) (2)描述女性外貌:用 her(她的)+ 身体部位 例句:This is her hair.(这是她的头发。) (3)描述自己外貌:用 my(我的)+ 身体部位 例句:This is my mouth.(这是我的嘴巴。) 3.身体部位名词的单复数规则(贴合三年级词汇): (1)不可数名词:hair(头发,整体概念)、hair 通常不用复数(特殊情况 “几根头发” 用 hairs,三年级暂不要求) (2)可数名词单数:mouth(嘴巴)、eye(眼睛)、nose(鼻子)(单个部位用单数) (3)可数名词复数:ears(耳朵)、hands(手)、legs(腿)(成对部位用复数) 4.连接词 And 的用法:用于连接两个并列的外貌描述句,表 “并且、还有”,使描述更有条理。 例句:This is his head. And this is his neck.(这是他的头。并且这是他的脖子。) (二)易混点区分(三年级必记) 1.区分 This is 与 These are: This is + 单数 / 不可数身体部位(如 hair、mouth) These are + 复数身体部位(如 ears、hands) 错误:This is his ears.(应为 These are his ears.) 2.区分 his 与 her: 描述男孩 / 男性:用 his(如 Tom 的外貌→This is his hair.) 描述女孩 / 女性:用 her(如 Lily 的外貌→This is her mouth.) (三)注意事项 1.描述外貌时,物主代词要与描述对象的性别一致(男性用 his,女性用 her)。 2.身体部位名词的单复数要与指示代词(This/These)、系动词(is/are)保持一致。 3.hair 作 “头发” 讲时,三年级阶段按不可数名词处理,不用加 s。 4.用 And 连接多个外貌描述句时,前面句子结尾用句号,And 开头首字母大写。 【大显身手】 一、语法填空。 1.This is ______ (his/her) face. He is my brother. 2.Look! This is her ______ (eye/eyes). It’s big. 3.This is ______ (his/her) hair. She has long hair. 4.These are his ______ (hand/hands). They are small. 5.This is ______ (his/her) nose. It’s red. 写作指引 一、写作。 假如你是 Baobao,现在要向朋友介绍一下你的外貌。请你写一段话,要求: 1. 语句通顺,语法正确;2.不少于5句话;3.句子要短,用你学过的简单词。 (一)写作指导: 1.核心句型:牢记 “This is my + 单数身体部位”(如 This is my nose.)和 “These are my + 复数身体部位”(如 These are my eyes.),确保句型正确。 2.常用词汇:运用学过的形容词(big/small/long/red/black)搭配身体部位,让描述更生动(如 long black hair, big eyes)。 3.写作结构:先问候自我介绍,再逐一描述 2-3 个单数部位和 1-2 个复数部位,最后加一句简单感受,逻辑清晰且符合三年级表达习惯。 (二)核心词汇和句型(选三年级学过的简单词) 1.身体部位(三年级必学) 单数:hair(头发)、eye(眼睛)、nose(鼻子)、mouth(嘴巴)、face(脸) 复数:eyes(眼睛)、ears(耳朵)、hands(手)、legs(腿) 2.外貌特征词(简单形容词) big(大的)、small(小的)、long(长的)、short(短的)、black(黑色的)、brown(棕色的)、red(红色的) 3.核心句型(介绍外貌基础主系表结构) (1)This is my + 单数身体部位.(这是我的……) 例句:This is my nose.(这是我的鼻子。) 例句:This is my face.(这是我的脸。) (2)This is my + 单数身体部位. It’s + 形容词.(这是我的……。它是…… 的。) 例句:This is my hair. It’s long.(这是我的头发。它是长的。) 例句:This is my mouth. It’s small.(这是我的嘴巴。它是小的。) (三)范文: Hello! I’m Baobao. This is my hair. It’s long and black.
