Unit 3 At the zoo（专项训练）-2025-2026学年人教PEP版（2012）英语三年级下册

Unit 3 At the zoo同步专项练习 第一部分：Unit 3 At the zoo培优核心必背知识点（做题先熟记，刷题不丢分） 一、单元核心培优必会单词（形容词+动物+基础词汇，必考默写）：thin 瘦的，fat 胖的；肥的，tall 高的，short 矮的；短的，long 长的，big 大的，small 小的，giraffe 长颈鹿，so 这么；那么，children 儿童；孩子们，tail 尾巴，zoo 动物园，elephant 大象，panda 熊猫，monkey 猴子，bear 熊。二、培优必考反义词专项（考试单选、填空高频考点）：tall（高的）—short（矮的），long（长的）—short（短的），big（大的）—small（小的），fat（胖的）—thin（瘦的），牢记四组核心反义词，做题快速辨析不混淆。三、培优重点必考短语（课本同步高频常考）：at the zoo 在动物园里，look at 看一看，that giraffe 那只长颈鹿，this elephant 这头大象，so tall 这么高，long nose 长鼻子，short tail 短尾巴，big ears 大耳朵，small eyes 小眼睛，fat panda 胖熊猫，tall and thin 又高又瘦，short and fat 又矮又胖。四、核心交际描述句型（培优重中之重，区分用法不混用）：1. Look at the+动物. 看……（某物/某动物）。2. It’s+形容词. 它是……的（整体外貌描述，高矮胖瘦大小）。3. It has+身体部位. 它有……（局部身体特征描述，鼻子、耳朵、尾巴等）。4. It’s+形容词 and+形容词. 它又……又……。5. Wow! So cute! 哇！好可爱啊！五、培优做题秒杀口诀（攻克全单元易错点）：It’s后面加样子，高矮胖瘦全用上；It has后面加部位，鼻子耳朵尾巴放；长短大小反义词，对应记忆不迷茫；look at要牢记，看啥后面加the；单数名词用is has，句型搭配不出错。 第二部分：Unit 3九大培优专项同步练习题（题型超多，全面特训） 题型一：选出不同类单词专项（20题，单词辨析培优，夯实词义分类） 从每小题A、B、C三个选项中，选出一个与另外两个不同类的单词，将正确序号填在括号内，专攻单词归类混淆、词性分不清易错点，熟练区分形容词、动物名词、场景词汇差异，夯实做题基础。 1.
