Unit1 We're friends 核心知识点（知识清单）-2025-2026学年译林版（三起）英语四年级下册

2026春译林版四下 Unit 1（We're friends） 核心知识点清单 一、核心句型：There be（表示“某地有某物”，即“存在有”） 1. There is（搭配：可数名词单数 / 不可数名词） · 基本结构：There is + 可数名词单数（a/an + 名词）/ 不可数名词 + （地点状语） · 例句：There is a bird in the tree. / There is some water in the bottle. · 核心规则：be动词的单复数由紧跟其后的名词决定，不可数名词永远搭配is。 · 高频易错点（必记）： ✘ 错误：There are some bread. / There is kite on the desk. ✔ 正确：There is some bread. / There is a kite on the desk. ✘ 混淆have与There be：The cup has tea.（侧重归属）→ There is tea in the cup.（侧重存在） 2. There are（搭配：可数名词复数） · 基本结构：There are + 可数名词复数 + （地点状语） · 例句：There are five apples in the bag. / There are many trees in the park. · 核心规则：可数名词复数前不加a/an，地点状语常放句末明确位置。 · 高频易错点（必记）： ✘ 错误：There is three cats. / There are in the classroom some students. ✔ 正确：There are three cats. / There are some students in the classroom. 3. 就近原则（There be句型的重难点） · 规则：当后接多个并列名词时，be动词的单复数仅由离它最近的名词决定。 · 例句：There is a pen and two books on the desk.（近的a pen是单数，用is）；There are two books and a pen on the desk.（近的two books是复数，用are） · 高频易错点：✘ 按名词总数量判断 → ✔ 只看“紧邻be动词”的那个名词。 二、核心句型：I want to share...（表达“想要分享”） 1. 基础搭配：want的两种用法 用法1：want + 名词/代词宾格（想要某物） · 结构：主语 + want(s) + 名词/代词宾格 · 规则：第三人称单数（he/she/it/单个人名）作主语时，want变wants；代词需用宾格（me/him/them等）。 · 易错点：✘ She want a ruler. / I want he. → ✔ She wants a ruler. / I want him. 用法2：want to + 动词原形（想要做某事） · 结构：主语 + want(s) + to + 动词原形 · 黄金规则：to后面的动词永远用原形，不受主语单复数影响。 · 易错点：✘ He wants play football. / She wants to plays basketball. → ✔ He wants to play football. / She wants to play basketball. 2. 固定短语：share ... with ...（和某人分享某物） · 结构：share + 分享的物品（名词/代词宾格） + with + 分享对象（人称代词宾格/名词） · 例句：I want to share my cake with Tom. / She shares her toys with us. · 核心规则：share是及物动词，后面必须先接分享的物品，再用with引出对象；with后接代词时，只能用宾格。 · 高频易错点（必记）： ✘ 介词误用：share my book to him → share my book with him ✘ 遗漏物品：I share with my friend → I share my apple with my friend ✘ 代词主格：share with she → share with her 3. 整合句型：I want to share ... with ... · 结构：I + want to + share + 物品 + with + 某人 · 解析：结合“want to do”和“share...with...”的核心规则，是本单元重点交际句型。 三、语法点：形容词作表语（描述人/物的特征） · 基本结构：主语 + be动词（am/is/are） + 形容词（+ 补充说明） · 例句：The girl is kind. / The apples are sweet and red. · 核心规则： a. be动词与主语保持一致：I→am，单数主语→is，复数主语→are； b. 多个形容词并列时，用and连接。 · 高频易错点：✘ The boys is tall. / She is happy but excited. → ✔ The boys are tall. / She is happy and excited. 四、核心句型：Why引导的特殊疑问句（询问原因） · 基本结构：Why + be动词（am/is/are） + 主语 + 其他？ · 回答规则：必须用Because开头，说明具体原因。 · 例句：—Why are you sad? —Because I lost my toy. / —Why is the dog angry? —Because it is hungry. · 高频易错点（必记）： ✘ be动词位置错误：Why the cat is scared? → Why is the cat scared? ✘ 回答遗漏Because：I'm late. I missed the bus. → I'm late because I missed the bus. 五、核心句型：How can you help me?（询问帮助方式） 1. 基础句型（第二人称） · 结构：How + can + you + help + 宾语（me/him/her等）？ · 回答结构：I/We + can + 动词原形 + 具体帮助方式。 · 例句：—How can you help me? —I can carry the books for you. 2. 拓展句型（第三人称） · 结构：How + can + he/she/they + help + 宾语？ · 黄金规则：can是情态动词，后面的动词永远用原形（help不变形），不受主语单复数影响。 · 高频易错点：✘ How you can help me? / How can she helps him? → ✔ How can you help me? / How can she help him? 六、程度副词：very / so / too（修饰形容词/副词） 副词 核心含义 关键用法 高频易错点 very 非常（程度深） 放在形容词/副词前；修饰动词时需说“very much”（放句末） ✘ I very like English. → ✔ I like English very much. so 如此（程度极深，可接结果） 放在形容词/副词前；可搭配“so...that...”；可接so many/much ✘ The book is very interesting that I read it twice. → ✔ The book is so interesting that I read it twice. too 太……（程度过甚，含否定） 放在形容词/副词前；隐含“超出合适范围” 混淆so与too：The bag is so heavy.（仅表程度）→ The bag is too heavy.（拿不动，含否定） 七、“许多”的表达：many / much / a lot of / lots of / a lot 1. 修饰名词的表达（核心区分可数/不可数） 表达 适用名词 使用场景 易错点 many 可数名词复数 否定句、疑问句为主 ✘ many milk → ✔ much milk much 不可数名词 否定句、疑问句为主 ✘ much apples → ✔ many apples a lot of / lots of 可数复数/不可数 肯定句、口语书面语通用；lots of更口语化 ✘ a lot books / lots books → ✔ a lot of books / lots of books 2. 修饰动词的表达：a lot · 用法：表示“非常、很”，仅修饰动词，放动词后。 · 例句：He knows a lot about animals. / I like music a lot. · 易错点：✘ He knows lots of about English. → ✔ He knows a lot about English. 八、语法点：人称代词宾格（me / him / her / us / them） · 核心功能：作动词宾语或介词宾语，表示动作的承受者。 · 常用搭配： a. 动词后：want him、help me、like them； b. 介词后：with us、for her、to them。 · 高频易错点：动词/介词后，坚决不用主格（I/he/we等）→ ✘ want she / with they → ✔ want her / with them。 译林版四年级下册 Unit 1 单元过关精品卷 （满分100分 时间40分钟） 班级：________ 姓名：________ 得分：________ 一、英汉互译（每小题1分，共10分） 1. 又大又强壮 ________________2. 用牙齿咬网 ________________ 3. 成为好朋友 ________________4. 走过 ________________ 5. 从那时起 ________________ 6. get out ________________ 7. make a hole ________________8. just then ________________ 9. in the net ________________ 10. share…with… ________________ 二、选出不同类的一项（每小题1分，共5分） ( ) 1.
