Unit3 Smart Learning语法讲解与练习 that/if/whether宾语从句详细讲解 一、宾语从句基础定义 放在动词、介词、形容词后，充当宾语的完整句子，叫做宾语从句。 宾语从句必考三要素（做题万能准则）： 1. 连接词：that/ if /whether（本单元只考这三类） 2. 语序：永远陈述句语序（主语在前，谓语在后，不倒装） 3. 时态：主现从不限、主过从必过、客观真理永一现 二、三大连接词 逐类精讲（单元核心） 1. that 引导宾语从句（陈述句变从句） （1）用法 当原句是陈述句,变为宾语从句时用that引导,无词义、不翻译、不作句子成分。 （2）省略规则（90%考点） ✅ 普通情况可省略：单个that从句,口语,书写均可省略 ❌ 绝对不能省略： ① 并列多个宾语从句,第二个及以后的that不可省 ② 从句位于句首时,that不可省 ③ 紧跟介词、插入语后,that不可省 （3）单元高频例句 I think (that) online learning is very useful. 我认为线上学习非常有用。 He said (that) he had learned a lot from smart learning. 他说他从智能学习中学到了很多。 The teacher told us that smart learning can improve our study efficiency. 老师告诉我们智能学习可以提升学习效率。（并列/正式句式不省that） 2. if / whether 引导宾语从句（一般疑问句变从句） （1）用法 原句是一般疑问句（是否问句）,变宾语从句用if /whether,翻译为“是否” 常用搭配动词：know/wonder/ask/find out/decide/doubt （2）通用规则 大部分场景if = whether 可互换 I wonder if/whether smart learning is helpful. 我想知道智能学习是否有帮助。 （3）必考:只能用 whether,不能用 if 的5种情况（中考满分必背） *从句后有 or not 时 I don’t know whether he will join the online class or not. ✅ *紧跟 介词 之后 It depends on whether you study hard. ✅ *不定式 to do 之前 I can’t decide whether to use this learning app. ✅ *句首引导宾语从句时 Whether he will accept the way is unknown. ✅ *与 or 连接并列从句时 I wonder whether we study online or study at school. ✅ 三、宾语从句三大核心规则（秒杀做题） 1. 语序规则（重中之重，必考错题点） 所有宾语从句,一律用陈述句语序：引导词+主语+谓语+其他 ❌ 错误：I wonder is he good at smart learning.（疑问语序） ✅ 正确：I wonder if he is good at smart learning.（陈述语序） 2. 时态规则（三句口诀背熟） ① 主现从不限：主句现在时态，从句根据实际情况用任意时态 I know that he studies online every day. ② 主过从必过：主句过去时态，从句统一用过去相关时态 He asked if I would use smart tools to study. ③ 客观真理永一现：从句是真理、客观事实，永远用一般现在时 The teacher said that the earth goes around the sun. 3. 否定前移规则（单元拔高考点） 主句主语为第一人称 I/We,谓语 think/believe/suppose/guess/expect,从句否定前移到主句 ❌ I think smart learning is not useless. ✅ I don’t think smart learning is useless. 四、高频易错点汇总 1. 分不清 if 两种含义：宾语从句中=是否；条件状语从句中=如果 2. 看到or not/介词/to do还用if (看到这几个标志词,直接用whether） 3. 从句误用疑问语序 五、单元万能写作句型 1. I think (that) smart learning makes our study more convenient. 我认为智能学习让我们的学习更便捷。 2. I wonder whether online learning is good for middle school students. 我想知道线上学习是否对中学生有益。 3. Many students don’t know if they should use learning apps in their free time. 很多学生不知道是否应该在空闲时间使用学习软件。 【巩固练习】 一、用正确连接词填空（that/if/whether） 1.
