译林版五年级英语上册 Unit 4 Safety first 重要语法知识点归纳+专项巩固练习 第一部分 重要语法知识点 语法1 情态动词should用法（单元核心安全句型） 1. 含义：should 意为“应该”，用来给出安全方面建议、规定；否定形式 shouldn’t = should not，表“不应该”。 2. 固定句式：主语 + should / shouldn’t + 动词原形（无论主语单复数，后面动词一律不变形） 例句：We should keep to the right. / You shouldn’t run on stairs. 语法2 情态动词may用法 may 表示“也许、可能”，表推测；may后接动词原形；否定may not； 区分：should侧重规则建议，may侧重可能性推测。 语法3 祈使句（安全警示句，高频考点） 1. 肯定祈使句：动词原形开头，表安全指令：Warm up before swimming. 2. 否定祈使句：Don’t + 动词原形，表禁止危险行为：Don’t pull others on stairs. 语法4 动词&名词变形考点 1. 动词动名词：pull-pulling、push-pushing、jump-jumping、climb-climbing、swim-swimming，用于like doing或作定语； 2. 名词复数：stair → stairs（楼梯固定用复数形式）；swimming pool 游泳池（名词作定语只用单数swimming）； 语法5 单元固定安全短语搭配 warm up 热身；pull 拉；push 推；climb 攀爬；hurt 受伤；keep to the right 靠右走；out of the way 不挡路；right now 立刻；swimming pool 泳池；stairs 楼梯 语法6 介词固定搭配 from 从……；on stairs 在楼梯上；in the swimming pool 在泳池里； 语法7 副词slowly用法 slow（形容词，慢的）→ slowly（副词，缓慢地），副词修饰行走、跑动这类动词，放在动词后：walk slowly 慢慢走； 语法8 并列连词用法 肯定句用and连接并列动作；否定建议句用or连接禁止行为：You shouldn’t run or push on stairs. 语法9 时态区分 本单元以一般现在时表通用安全规则，无过去时考点，所有安全标语、建议均用原形动词。 第2部分 课后巩固习题 一、用所给单词的适当形式填空 1.
