If + 从句，主句（逗号隔开） If she comes, I will tell you the news. 2. 主句 + if + 从句（不加逗号） I will tell you the news if she comes. 否定与疑问 · 否定：If you don’t get up early, you will be late. · 一般疑问：Will you join us if we have a picnic? 四、易混区分：if 两种含义 1. if = 如果（条件状语从句）→ 主将从现 2. if = 是否（宾语从句）→ 时态随主句，不受主将从现限制 例：I don’t know if he will come tomorrow.（宾语从句，可用 will） 五、高频易错点 1. 从句主语为第三人称单数，动词忘记变三单： ❌ If he go, I will follow. ✅ If he goes, I will follow. 2. 在 if 从句里错误添加 will； 3. 语序混乱，if 放句首不加逗号； 4. 混淆 if “如果” 和 “是否”，乱用时态规则。 【典例例题】 If it ____ fine tomorrow, we ____ to the mountain. A. is; will go B. will be; go C. is; go D. will be; will go 【命题解读】 考点三合一：①主将从现时态规则；②if 条件句时态区分；③be 动词主谓一致 线索：if 引导条件状语从句，遵循 “主将从现”；从句用一般现在时，主语 it 搭配 is；主句用一般将来时 will + 动词原形，排除 B、C、D。 结构规则：If + 一般现在时从句，主句 will/be going to + 动词原形；if 置于句首，从句末尾加逗号。 【易错警示】 ①不记 “主将从现”，从句误用 will（错选 B、D）； ②主句忘记使用将来时，前后都用一般现在时（错选 C）； ③if 放句首时遗漏逗号，书写丢分； ④混淆 if “如果”（条件句）与 if “是否”（宾语从句）时态规则。 【巩固提升1】 1．________ you love life, don’t waste time and enjoy every minute.

The most common way is face-to-face communication. When talking to our friends, family, or teachers in person, we can see their facial (面部的) expressions, body language, and hear their voices. This helps us understand not only the words they say but also their real emotions. When we’re sharing exciting news with a friend, a face-to-face talk makes the moment meaningful. Another form is communication through social media. Apps like WeChat, QQ, or Douyin help us to contact people far away easily. We can share photos of our trips, short videos of pets, or interesting ideas without difficulty. However, we can’t see the real-time reactions (反应) of the other person. When we send something on WeChat Moments, we have to wait for people’s comments (评论), likes, or replies to know if they find it interesting. Phone calls are also popular. We can have a quick conversation when we are busy, such as on the way to school or between after-school classes. Unlike face-to-face communication, we can’t see each other, but we can still feel the clear emotion through the tone (语气) of voice. In short, each form of communication has its own strengths and shortcomings (缺点). We should choose the right one according to different situations in our daily lives. 54．What is one of the most common forms of communication according to the passage? A．Through social media. B．Through phone calls. C．Face-to-face communication. D．By dropping a line. 55．What can we get from face-to-face communication? A．Only the words people say. B．Only the tone of their voice. C．The real feelings of people. D．The text messages people send. 56．What is the structure of the passage? A． B．C． D． 57．What can we infer (推断) from the passage? A．Phone calls are not useful at present. B．Social media is the best way to communicate. C．We should only use face-to-face communication. D．We should choose right communication forms by situations. 【答案】54．C 55．C 56．D 57．D 【导语】本文介绍了三种常见的沟通方式：面对面交流、社交媒体沟通和电话沟通。 【详解】54．第二段首句“The most common way is face-to-face communication.”直接点明最常见的沟通方式是面对面交流。 55．第二段“This helps us understand not only the words they say but also their real emotions.”直接说明面对面交流能让我们理解对方的话语还能理解其真实的情感。 56．第一段：开篇点题，指出人们有不同的沟通方式且都很重要；第二、三、四段：分别介绍面对面、社交媒体、电话三种具体的沟通方式，阐述各自特点；第五段：总结全文，强调每种沟通方式各有优劣，应根据场景选择合适的方式。对应D项。 57．最后一段末句“We should choose the right one according to different situations in our daily lives.”可推断，我们应该根据不同情况，选择合适的沟通方式。 19 / 21 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 专题05 if引导的条件状语从句 内容导航 01 复习目标→ 明考向、知权重、晓关联、以目标导学，以考向定标 02 知识重构 → 系统讲解核心知识，重构整合形成体系 脉络重构：快速扫描高频考点，定位薄区 典例破题：精选例题，呈现思路点拨+规范解答+方法提炼 巩固提升：趁热打铁练一练，强化巩固所学 03综合通关 → 综合演练，梯度设题；查漏补缺，闭环收官 知识点 常考考点 命题风向 if 引导的条件状语从句 1. 核心规则：主将从现（主句将来时，从句一般现在时） 2. 句式分类：零条件句（客观真理）、第一条件句（将来可能发生） 3. 句式变换：否定句、一般疑问句转换 4. 引导词辨析：if（如果） vs when（当…… 时） 5. 易错点：从句不使用 will，if 放句首时加逗号分隔 单选、句型转换；完形填空、书面表达，用于表达假设、条件、计划 脉｜络｜重｜构 考｜点｜精｜讲 一、核心定义 if 意为 “如果”，引导条件状语从句，表示主句动作发生的前提条件，分两类考点句型。 二、零条件句（客观真理 / 自然常识） 规则：主从句均使用一般现在时，描述永远成立的事实。 例句：If water boils, it turns into steam. 三、第一条件句（考试重中之重，主将从现） 时态铁律 从句（if 后面半句）：一般现在时，禁止使用 will 主句：一般将来时（will /be going to + 动词原形） 两种语序 1.

Their 43 (one) stop was Guizhou. They played two 44 (friend) basketball games with villagers in Taipan Village, Tàijiang County. The “competition” is different from the usual ones.

Ben I found a game dazi and we agreed to play games together. However, when I went online on time, I found that I couldn’t find him! I know we can’t trust (信任) online partners, but I still feel sad because he disappeared without telling me. Chen Fei I once met a great meal dazi. Thanks to him, I got to try delicious food and learn about fun places to visit. Sharing meals with someone like this makes the experience much more enjoyable!

People communicate in different forms and these forms are all important. The most common way is face-to-face communication. When talking to our friends, family, or teachers in person, we can see their facial (面部的) expressions, body language, and hear their voices. This helps us understand not only the words they say but also their real emotions. When we’re sharing exciting news with a friend, a face-to-face talk makes the moment meaningful. Another form is communication through social media. Apps like WeChat, QQ, or Douyin help us to contact people far away easily. We can share photos of our trips, short videos of pets, or interesting ideas without difficulty. However, we can’t see the real-time reactions (反应) of the other person. When we send something on WeChat Moments, we have to wait for people’s comments (评论), likes, or replies to know if they find it interesting. Phone calls are also popular. We can have a quick conversation when we are busy, such as on the way to school or between after-school classes. Unlike face-to-face communication, we can’t see each other, but we can still feel the clear emotion through the tone (语气) of voice. In short, each form of communication has its own strengths and shortcomings (缺点). We should choose the right one according to different situations in our daily lives. 54．What is one of the most common forms of communication according to the passage? A．Through social media. B．Through phone calls. C．Face-to-face communication. D．By dropping a line. 55．What can we get from face-to-face communication? A．Only the words people say. B．Only the tone of their voice.
