Unit6语法讲解及习题：Conditional sentences (1)（第一类条件句）2025-2026学年沪教版七年级英语上册

沪教（牛津）英语七上Unit6语法讲解及习题 Conditional sentences (1)（第一类条件句） 一、语法核心讲解 本单元语法重点是 第一类条件句（Conditional sentences (1)），用于谈论“可能发生的动作”以及“这些动作可能带来的结果”。 1. 基本结构与规则 核心结构：If + 一般现在时, 主句（一般将来时 / 情态动词 can / should + 动词原形） if从句（if-clause）：描述一个可能的条件或动作，动词用一般现在时。 主句（main clause）：描述这个条件下可能产生的结果，动词用一般将来时（will / be going to）或情态动词（can / should）。 位置灵活： if从句在前，主句在后：If you visit the park, you will have a lot of fun. 主句在前，if从句在后：You will get a bird's-eye view of the whole park if you ride on the cable car. 2. 时态规则（重中之重） if从句：无论主句时态如何，if从句中的动词必须使用一般现在时。 例：If you go to Beijing, you can visit the Summer Palace. 主句： 表示预测或结果：使用一般将来时（will / be going to）。 例：If you try the rides, you will get excited. 表示建议或能力：使用情态动词 can / should + 动词原形。 例：If you want to relax, you can go to the beach. 例：If you are brave enough, you should try the roller coasters. 二、综合练习题 题型1：单项选择 1.
