Unit 12Section A单元知识点讲解2022-2023学年人教版英语七年级下册

Unit 12 What did you do last weekend? Section A 教材知识全解 讲透知识 查漏补缺 知识点一 感叹句的用法和结构 教材原文 How interesting!多有趣啊！ 本句是how引导的感叹句,how用来修饰形容词或副词,此类感叹句的结构为“How+形容词／副词(＋主语＋谓语)！”.如: How beautiful the girl is!这个女孩真漂亮啊！ How fast the boy is running!那个男孩跑得真快啊！ 拓展what也可以引导感叹句,what用来修饰名词.常见的结构有: What a/an+形容词+可数名词单数(+主语+谓语)！ What a beautiful girl she is!她是一个多么漂亮的女孩啊！ What+形容词＋不可数名词(＋主语＋谓语)！ What good weather it is! 多好的天气啊！ What+形容词＋可数名词复数(＋主语＋谓语)！ What hard-working students they are! 他们是多么努力的学生啊！ 例-All of my classmates have passed the PE test. -________ exciting the news is! A. What B. What an C. How D. How an 解析 本题考查感叹句的结构.感叹形容词exciting 要用how,再根据对应的结构“How+形容词／副词＋主语＋谓语！”可知答案为C. 答案 C 知识点二 由 stay up 归纳“动词＋up”短语 教材原文 I stayed up late to watch the soccer game.我熬夜到很晚看了足球赛. stay up是固定搭配,意为“熬夜”.如: She stayed up until 2:00 am.她熬夜到凌晨两点. 拓展常见的“动词＋up”结构的短语还有: get up起床,起来;look up查阅,向上看;give up放弃;cut up 切碎;grow up 长大;wake up 叫醒;put up搭建,张贴;pick up 捡起 例(2020黑龙江哈尔滨香坊区教育质量综合评价)-How was your weekend, Bill? -It was good, but I'm kind of tired now. I________ late to play computer games. A. put up B. looked up C. stayed up 解析put up 搭起,张贴;look up查阅,向上看;stay up熬夜.根据题干中的“我现在有点儿疲惫”可推断,我“熬夜”玩电脑游戏了,stayed up符合题意. 答案 C 知识点三run away的用法 教材原文The cat quickly ran away.那只猫飞快地逃跑了. run away意为“逃跑;跑开”,其中run意为“跑”,过去式是ran,属于不规则变化.如: The thief tried to run away, but he failed.那个小偷试图逃跑,但失败了. 例 用括号中所给词的适当形式填空 The young children________ (run) to the gate of the museum ten minutes ago. 解析 本题考查动词时态.根据 ten minutes ago 可知,该句的时态是一般过去时,run的过去式是ran. 答案ran 学科网（北京）股份有限公司 $
