知识清单·大同版三年级上册 Unit3 In my schoolbag 知识梳理 知识点拨 【考点一】询问与回答书包内物品的句型 【考点二】单复数物品的表达 【考点三】have”和“has”的用法区别 【考点四】“文房四宝”相关表达 【考点五】询问物品数量的句型 考点一：询问与回答书包内物品的句型 1. 核心句型： —What do you have in your schoolbag?（你书包里有什么？）—I have + 物品.（我有……） 解析：这是日常询问和描述书包内物品的基础句型，“have”表示“拥有”，主语是第一人称“I”时用原形“have”。 例句：—What do you have in your schoolbag?—I have a book and a pencil case. 2. 拓展句型：描述他人拥有某物——He/She has + 物品. 解析：当主语是第三人称单数（he/she/单数人名）时，“have”要变为“has”。 例句：She has two erasers.（她有两块橡皮。） 【大显身手】 一、单项选择题。 （ ）1. —What do you have ____ your schoolbag?—I have a pen. A. on B. in C. at （ ）2. She ____ three notebooks. A. have B. has C. is （ ）3. —What is this?—____ a pencil case. A. It is B. They are C. This is （ ）4. I have ____ eraser and ____ book. A. a; an B. an; a C. an; an （ ）5. —What ____ they?—They are rulers. A. is B. are C. am 考点二：单复数物品的表达 —It is an eraser. —They are rulers. 规则：大部分可数名词变复数时，在词尾加“s”。 例：pencil→pencils（铅笔）、book→books（书）、eraser→erasers（橡皮）、notebook→notebooks（笔记本） 1. 单数物品：It is a/an + 物品. 解析：“it”指代单数物品，“a”用于辅音音素开头的单词前（如 a pen），“an”用于元音音素开头的单词前（如 an eraser）。 例句：It is an eraser.（它是一块橡皮。） 2. 复数物品：They are + 物品（复数）. 解析：“they”指代复数物品，物品名称需用复数形式（一般在词尾加“s”，如 pencil→pencils）。 例句：They are rulers.（它们是直尺。） 【大显身手】 一、判断并改错（对打“√”，错打“×”，并在横线上写出正确句子） 1. He have a pencil.（ ）_________ 2. I has two pens.（ ）_________ 3. It is a eraser.（ ）_________ 4. They is books.（ ）_________ 5. What do you has in your schoolbag?（ ）_________ 考点三：“have”和“has”的用法区别 “‌have”‌ 是英语中常用的动词，意思是“拥有”或“存在”。其用法和含义需结合具体语境分析： 语法结构解析‌ 主语是第一人称（I）、第二人称（you）或复数（we/they）时，用“have”。 例：I have a ruler.（我有一把直尺。）； They have two pencil cases.（他们有两个铅笔盒。） 主语是第三人称单数（he/she/it）时，用“has”。 例：He has a pen.（他有一支钢笔。）； It has a big schoolbag.（它有一个大书包。） 注：‌作为助动词‌：与过去分词连用构成现在完成时， 例： I have finished my homework.（我已经完成作业了）。 常见短语 1.‌have to‌：表示“不得不”，如 I have to go now.（我现在得走了）。 2.‌have got‌：口语中表示“得到”，如 I have got your message.（我已收到你的消息）。 特殊用法 ‌have sb/sth + 介词短语‌：表示“使某人/某物处于某种状态”，如 She has the book on the table.（她把书放在桌子上了）。 ‌have sth to do‌：表示“有责任或义务做某事”，如 We have to finish the project today.（我们今天必须完成项目）。 否定句‌：无直接对应的反义词，但可通过语境使用否定形式表达相反含义，如 I don't have time.（我没有时间）。 【大显身手】 一、根据提示补全句子 1. I ____（have/has）a schoolbag. It is blue. 2. —What do you have in your pencil case?—I have three ____（pencil/pencils）and one ____（eraser/erasers）. 3. She ____（have/has）a notebook.

A. a book B. paper C. a pencil case 考点五：询问物品数量的句型 — How many erasers are there? 有多少块橡皮？ —Two. 两块。 句型结构：How many + 复数物品 + are there?”意思是：有多少....? 这个句型是在表达物品的数量有多少的时候使用，其中涉及名词的单复数，以及根据实际数量回答问题。需注意“How many”后必须接可数名词复数，回答时需明确数量（如“Three.”“Two.”）。 注意：在本单元中没有频繁的在对话中出现，但是会作为题型去考查问答的方式，如36页的read and circle和34页的对话图片中的引导问题。 【大显身手】 1、 选择正确的单词填空 1. —How ______ (much/many) books do you have? 2. —How many ______ (pencil case/pencil cases) are there on the desk? 3. —How many rulers______ (do/does)your friend have? 4. —_______(What/How) many ______ erasers can you see in the schoolbag? 5. —How many notebooks _______(are/is) there in your pencil case? 二、情景对话匹配（将A栏的句子与B栏的答句用线连起来） （ ）1. —How many ______ are there in your schoolbag? —There are three.
