Unit 3 Yummy food（期中知识清单）英语外研版三起三年级下册（新教材）

知识清单·外研版三起三年级下册 Unit3 Yummy food 知识梳理 知识点拨 【考点一】一般疑问句 Do you like...? 及其回答 【考点二】We've got... 句型与名词复数 【考点三】Let's... 祈使句 考点一：一般疑问句 Do you like...? 及其回答 —Do you like apples? —No, I don't. I like grapes. 解析 1. 问句结构：Do + 主语 (you/we/they) + 动词原形 (like) + 宾语? Do 是助动词，用于一般现在时、主语为非第三人称单数（you/we/they）的疑问句中。 like 是实义动词，意为“喜欢”，后接可数名词复数或不可数名词。 2. 答句结构： 肯定回答：Yes, 主语 + do. 否定回答：No, 主语 + don't (do not). 答句主语要与问句主语保持一致（you → I/we）。 3. 易错点： 主语是第三人称单数（he/she/Tom）时，问句要变为 Does he/she like...?，答句为 Yes, he/she does. / No, he/she doesn't. like 后接可数名词时，通常要用复数形式表示一类事物（如 apples, grapes）。 【大显身手】 1. —Do you like ______ (tomato)? —Yes, I do. 2. —Does your sister like chicken? —No, she ______. (do not) 3. I like ______ (strawberry). They are sweet. 4. —Do you like rice? —______ A. Yes, I am. B. No, I don't. C. Yes, it is. 5. （句型转换）I like carrots.（改为否定句） I ______ ______ carrots. 考点二：We've got... 句型与名词复数 —Now we've got eggs. 解析 1. 句型含义：We've got = We have got，意为“我们得到了/我们有……”，用来表示拥有或获取某物。 2. 名词复数变化规则： 一般情况：直接加 s → apple → apples 以 s/x/ch/sh 结尾：加 es → box → boxes 以 辅音字母 + o 结尾：加 es → tomato → tomatoes, potato → potatoes 以 辅音字母 + y 结尾：变 y 为 i 再加 es → strawberry → strawberries 3. 易错点： tomato 和 potato 的复数是 tomatoes 和 potatoes，容易误写为 tomatos。 fish 表示“鱼肉”时不可数，表示“鱼的条数”时单复数同形。 【大显身手】 1. We've got three ______ (egg). 2. I've got two ______ (orange). ( )3. Look! We've got some ______. A. strawberrys B. tomatoes C. noodle 4. We've got corn.（改为一般疑问句） ______ you ______ corn? 5. She has got a ______ (carrot).（改为复数句） They have got some ______. 考点三：Let's... 祈使句 Let's make a salad together! Let's get ready for lunch together, too! 解析 1. 句型结构：Let's + 动词原形 + 其他，意为“让我们……吧”，用来提出建议或邀请。 2. 用法说明： Let's = Let us，后必须接动词原形。 常与 together 连用，强调“一起做某事”。 3. 易错点： 不要写成 Let's to do...，Let's 后直接跟动词原形。 反义疑问句：Let's... 后用 shall we?；Let us... 后用 will you?。 【大显身手】 1. Let's ______ (go) to the farm. 2. Let's ______ (make) a sandwich. 3. Let's ______ ready for breakfast. A. get B. to get C. getting 4. Let's eat noodles.（改为否定句） Let's ______ ______ noodles. 5. —Let's pick grapes! —______ ______!（好主意！） 写作指引 My Favorite Breakfast 写作指导及范文 一、写作 请以“My Favorite Breakfast”为题，写一篇英语短文，介绍自己最喜欢的早餐，需包含：常吃的早餐食物；食物的味道与营养；吃早餐后的心情与感受。 要求：1. 句子通顺，思路清晰有条理。2. 不少于 50 字。 （一）写作指导（分 3 步，可直接套用） 第一步：梳理写作思路（先想 “3 个关键信息”） 关键部分 思考方向（举例） 1. 时间、事物、喜好 早上通常吃什么早餐 2. 细节介绍 食物口感、好不好吃、有什么营养 3. 心情感受 吃完早餐开心吗？能活力满满吗？ 第二步：拆解写作结构（分 “开头 - 中间 - 结尾”，每部分写 1-2 句） 第三步：必用核心句型 写作时优先用这些前单元学过的句型，既符合要求又不易出错： My favorite...is...
