Unit 3-2026年新三年级英语暑假自学课 （单元知识整合） 一、必会词汇 schoolbag 书包book 书notebook 笔记本pencil 铅笔pen 钢笔ruler 直尺 eraser 橡皮 pencil case 铅笔盒 one 一 two 二 three 三 four 四 five 五 six 六 seven 七 eight 八nine 九ten 十 二、重点短语 6 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 in my schoolbag 在我的书包里 in the pencil case 在铅笔盒里 have a schoolbag 有一个书包 how many 多少 one book 一本书 two pencils 两支铅笔 three erasers 三块橡皮 三、核心句型 1. What is in your schoolbag? 你的书包里有什么？ 2. I have a schoolbag. 我有一个书包。 3. I have a pencil and a ruler. 我有一支铅笔和一把直尺。 4. She has three pencils. 她有三支铅笔。 5. How many erasers are there? 有多少块橡皮？ 6. It is a notebook. 它是一本笔记本。 7. They are pens. 它们是钢笔。 辨析:1. I have… / She has… 区别 第一人称用 have（我/我们有）；第三人称单数 she/he/人名 用 has（她/他有），不能混用。 2. 单数用 It is… 复数用 They are… 单个物品用 It is…；两个及以上物品要用 They are… 3. How many + 可数名词复数 how many 后面一定要跟名词复数，如 how many pencils，不能说 how many pencil。 4. a / an 用法 辅音发音开头用 a（a book, a pen）；元音发音开头用 an（an eraser, an apple）。 重难点突破（have/has和there be句型区分和用法） 1. have & has 用法 - I / You / We / They + have - He / She / It / 单个人名 + has 2. 可数名词单复数 一般名词直接加s：pencil→pencils pen→pens book→books 3. There is / There are 初步认知 There is + 单数物品（有一个……） There are + 复数物品（有多个……） 4. a/an 不定冠词用法 元音音素开头单词前用 an，辅音音素开头用 a。 【进阶训练】用所给词适当形式填空。 1. I ______ (have) a new schoolbag. 2. She ______ (have) three pencils. 3. How many ______ (book) do you have? 4. This is ______ (an) ruler. 5. They are seven ______ (pen). 解析：1. have：主语是第一人称I，后面固定用 have。 2. has：主语She是第三人称单数，要用has。 3. books：How many 后必须接名词复数，book变books。 4. a：ruler以辅音音素开头，用a，不用an。 5. pens：seven 七，后面接可数名词复数，pen变pens。 . 知识演练场 一、单项选择 ( ) 1.
