Unit 1 Welcome back to school！同步练习-三年级下册英语专项培优训练 第一部分：Unit 1 Welcome back to school！培优核心必背知识点（做题培优核心，熟记再刷题） 一、单元核心培优主题：新学期返校问候交际、介绍自己和新朋友、认识不同国家国籍、区分男孩女孩人物称呼、简单身份问答与日常交流。二、培优必会核心单词（易混重点）：UK英国，Canada加拿大，USA美国，China中国，student学生，pupil小学生，teacher教师，boy男孩，girl女孩，new新的，friend朋友，today今天，welcome欢迎，where哪里，from来自。三、培优重点区分短语（考试易错）：welcome back to school欢迎回到学校，go back home回家，a new friend一个新朋友，my new teacher我的新老师，from China来自中国，in the UK在英国，a tall boy一个高个子男孩，a nice girl一个可爱的女孩。四、核心培优必考句型（灵活运用必考）：1. Welcome back to school! 欢迎回到学校！2. Nice to see you again. 很高兴再次见到你。3. Where are you from? 你来自哪里？I’m from+国家. 我来自……4. This is my new friend. 这是我的新朋友。5. He is a boy. She is a girl. 区分男他女她培优易错点。6. We have two new friends today. 我们今天有两位新朋友。五、培优做题关键口诀（秒杀易错题）：国家名称大写首字母，男He女She别乱用；from搭配国家地名，be from固定不改动；介绍别人用This is，打招呼匹配不乱选；单数is复数are，培优变形不出错。 第二部分：Unit 1八大培优专项同步练习题（题型丰富，培优拔高专用） 题型一：单项选择题培优专项（40题，易混辨析+语境拔高，核心必考） 仔细阅读每小题句子，结合单元培优知识点、语境交际、单词辨析、be动词用法、he/she区分、国家单词搭配，选出最佳答案，将序号填在括号内。本题侧重培优易错点辨析，基础+拔高分层出题，攻克平时易混丢分点。 1.
