Unit 6 Travelling around Asia-2026-2027学年七年级英语上册语法专项（沪教版）

U6 Travelling around Asia 语法专项 章 语法概览 ★条件状语从句（一型Conditional sentences I) 语法精讲精练一 1.核心结构：主将从现 这是中考/期末考最核心、最基础的考点，即“主句用一般将来时，从句用一般现在时”。 结构公式：f+主语+动词一般现在时，主语+w训+动词原形 ★重要：千万不能出现“fwl.”的结构(f引导宾语从句时除外，详见后面易混点)。 If it rains(aim)tomorow,we will stay(stay)at home..(如果明天下雨，我们就待在家里。) If you study(study)hard,you will pass (pass)the exam. (如果你努力学习，你就会通过考 试。) 结构分解 主语(Subject) 从句(If-clause) 主句(Main clause) 一般现在时(Simple 一般将来时(Simple 时态 Present) Future) 例句1 We If it rains tomorrow will stay at home 例句2 You If you study hard will pass the exam 例句3（否 You 定) If you don't hurry up will miss the bus 例句4(be动 She If she is free this evening will come to my party 词) 例句5（情 He If he can swim will go to the beach 态动词) 记忆口诀：f从句用现在，主句将来不会改。或者 “主将从现”。 2.核心考点：f从句的位置与标点 f引导的从句可以放在主句之前或之后。 f从句在前：从句+逗号+主句 If you are late,the teacher will be angry f从句在后：主句+f从句（无逗号） The teacher will be angry if you are late 3.核心语法点：副词的“比较级”用在f句中 当句意表达“越…，就越…”时，使用he+比较级，he+比较级的结构，这其实是两 个并列的从句。 结构：The+比较级..，he+比较级. The more you read,the more you will leamn. (你读得越多，就会学到越多。) The harder you work,the better you will be..(你越努力，就会越好。) 4.易混难点辨析：f引导的宾语从句s.条件状语从句 这是中考语法填空和单选中的“陷阱”题。 从句类型 含义 时态规则 示例 I don't know if he will f条件状语 “如果” 主将从现 come. (我不知道是否他 从句 会来。) 根据需要，主从句时态保 I don't know if he will f宾语从句 “是否”(=whether) 持一致。常用一般将来 come.（我不知道是否他 时。 会来。) ★判断方法（核心技巧）： 看f后面的从句是回答“什么情况下发生？”（条件句一一用一般现在时），还是回答“什 么内容？”（宾语从句一一用将来时）。 如果…就…：Ifit1ains,I will stay.(条件，用一般现在时) 不知道是否…：I wonder if it will rain.(不知道的内容，用将来时) 5.拓展：unless替换f.not unless意为“如果不”，相当于f.not。 结构：Unless+一般现在时，主句+w训 You will fail the exam unless you study hard.(=If you don't study hard,you will fail.)( 不努力学习，你就会考试不及格。) We will go for a picnic unless it1ains.(=If it doesn't rain,we will go.)(除非下雨，否则我们会 去野餐。) 二、专项训练 (一)单项选择 1.Ifit sunny tomorrow,we to the park.
