教学课件 冀教英语七年级上册 Unit3 语法专项—— 动词be与have/has的用法 全解精讲+分层练习 1 学习目标 掌握动词be(am/is/are)的含义、形式及基本用法 牢记have/has的含义、人称变化及用法区别 能熟练区分be动词与have/has的用法,避免混淆 掌握have/has的一般疑问句、否定句变法 能完成各类题型,在语境中正确运用两类动词 动词be·核心认知 动词be是英语中最基础的动词,核心含义是“是、在” 关键特点:随主语的人称和数变化,有3种形式:am、is、are 作用:用来表示人或事物的身份、状态、地点、年龄等 记忆口诀:我(I)用am,你(you)用are,is连着他她它 易错提醒:不可随意混用am、is、are,需结合主语判断 动词be·形式与主语对应表 主语人称/数 对应be动词形式 示例 第一人称单数(I) am I am a student. 第二人称单/复数(you) are You are my friend. 第三人称单数(he/she/it/单数名词) is He is tall. 复数(we/they/复数名词) are They are happy. 动词be·基本用法(一):表身份/职业 核心功能:用来介绍人或事物的身份、职业,说明“是什么” 基本结构:主语 + am/is/are + 职业/身份名词 例句1:I am a student.(我是一名学生。)—— 表身份 例句2:She is a teacher.(她是一名老师。)—— 表职业 拓展:可加from短语,补充身份背景,如I am a student from China. 动词be·基本用法(二):表特征/状态 核心功能:描述人或事物的外貌、性格、状态,说明“怎么样” 基本结构:主语 + am/is/are + 形容词 例句1:He is tall and thin.(他又高又瘦。)—— 表外貌 例句2:They are happy.(他们很开心。)—— 表心情状态 常见形容词:tall(高的)、happy(开心的)、old(老的)、new(新的) 动词be·基本用法(三):表地点/年龄 1. 表地点:说明人或事物所在的位置,后接介词短语 例句:The pen is in the bag.(钢笔在包里。) 2. 表年龄:说明人的年龄,后接数字+years old(可省略) 例句1:I am twelve years old.(我十二岁。) 例句2:She is ten.(她十岁。)—— 省略years old,更简洁 注意:地点和年龄前,be动词需根据主语正确选择 动词be·易错点辨析 1. 主语为this/that(单数),用is;these/those(复数),用are 错误:This are my book. 正确:This is my book. 2. 主语为单数名词(如the book),用is;复数名词用are 错误:The flowers is beautiful. 正确:The flowers are beautiful. 3. I后只能用am,不可用is/are;you后只能用are 动词have/has·核心认知 have/has是表示“拥有、具有”的动词,核心含义是“有” 关键特点:has是have的第三人称单数形式,随主语变化 作用:用来表示拥有物品、身体特征,也可表示经历/情感 记忆口诀:主语三单用has,其余人称全用have 区分:have用于多人/复数,has仅用于第三人称单数 have/has·形式与主语对应表 主语人称/数 对应形式 示例 I/we/you/they/复数名词 have I have a pen. he/she/it/单数名词 has She has long hair. 提示:第三人称单数=he/she/it+单数名词(如the dog, Tom) have/has·基本用法(一):拥有物品 核心功能:表示某人拥有某件物品,说明“有什么东西” 基本结构:主语 + have/has + 物品名词 例句1:I have a new schoolbag.(我有一个新书包。) 例句2:He has a bike.(他有一辆自行车。) 拓展:可加形容词修饰物品,如She has a nice toy. have/has·基本用法(二):拥有特征/情感 1. 表身体特征:描述人或动物的外貌、身体部位 例句:He has big eyes and a small mouth.(他有大眼睛、小嘴巴。) 2. 表情感/经历:拓展用法,符合七年级难度,表“经历、感受” 例句1:I have a good time today.(我今天过得很开心。) 例句2:She has a happy family.(她有一个幸福的家庭。) have/has·一般疑问句(重点) 两种变法,均可使用,重点掌握第二种(更常用) 1. 直接提前法:have/has提前,主语紧跟其后 例句:Have you a ruler?(你有尺子吗?)/ Has he a cat?(他有猫吗?) 2. 借助助动词法:第三人称单数用Does,其余用Do 例句:Do you have a ruler? / Does he have a cat?(更常用,易错点) have/has·否定句(重点) 两种变法,与一般疑问句对应,避免混淆 1. 直接加not法:have后加not(haven’t),has后加not(hasn’t) 例句:I haven’t a pen.(我没有钢笔。)/ She hasn’t a book. 2. 借助助动词法:don’t(其余人称)/ doesn’t(三单)+ have 例句:I don’t have a pen. / She doesn’t have a book.(更常用) 易错提醒:doesn’t后必须接have原形,不能写has be动词与have/has·核心区别(重点) 两者含义、用法完全不同,重点区分,避免混用 1. be动词:表“是、在”,强调状态、身份、地点,后接表语 结构:主语 + am/is/are + 表语(形容词/名词/介词短语) 2. have/has:表“拥有”,强调所属关系,后接宾语 结构:主语 + have/has + 宾语(物品/特征等) be动词与have/has·例句对比 通过对比,快速区分两种动词的用法 1. 表特征:She is tall.(be动词,表“她是高的”,状态) She has long hair.(has,表“她有长头发”,拥有) 2. 表身份/物品:He is a student.(be动词,表身份) He has a schoolbag.(has,表拥有物品) 3. 表地点/拥有:The book is on the desk.(be动词,表地点) I have a book.(have,表拥有) 基础练习1:用am/is/are填空 请根据主语,填入合适的be动词形式 1.
