Unit4 Our Memory语法讲解与练习 特殊疑问词（wh-）引导宾语从句精讲+专项练习 一、基础定义 由特殊疑问词（wh-/how系列）引导的宾语从句，对应主句“想知道/询问/明白”的具体信息，翻译为：……某人/某事/何时/何地/为何/如何……。 本单元三大类引导词： 疑问代词：what / who / whom / whose / which 疑问副词：when / where / why / how 疑问词组：how long / how far / how many / how much / how often / how soon 二、核心做题三要素（必考满分准则） 1. 连接词：保留原特殊疑问词，不增词、不丢词、不替换 特殊疑问句变宾语从句：去掉问号，保留疑问词，不用that/if/whether 2. 语序：永久陈述语序（中考第一易错点） 公式：特殊疑问词 + 主语 + 谓语 + 其他（绝对不倒装、不加do/does/did） ❌ 错误：I don’t know how can I improve my memory. ✅ 正确：I don’t know how I can improve my memory. 3. 时态：和that/if宾语从句规则完全一致 ① 主现从不限：主句现在时态，从句任意时态 ② 主过从必过：主句过去时态，从句统一倒退为过去相关时态 ③ 客观真理永一现：客观事实永远用一般现在时 三、各类引导词精讲+单元例句 1. what 引导（什么，做主语/宾语） I want to know what can help us remember things better.（错） ✅ I want to know what helps us remember things better. 我想知道什么能帮助我们更好地记忆。 2. who/whom 引导（谁） who 作主语；whom 作宾语（口语可通用who） I wonder who invented these memory skills. 我想知道是谁发明了这些记忆技巧。 3. which/whose 引导（哪一个/谁的） Can you tell me which way is the best to improve memory? 你能告诉我哪种方法是提升记忆力最好的方法吗？ 4. when/where/why/how 引导（何时/何地/为何/如何） He asks why memory is important for students. 他问为什么记忆力对学生很重要。 We want to know how we can train our brain. 我们想知道我们如何训练大脑。 5. how 疑问词组（高频拔高） how long（多久/多长）、how often（多久一次）、 how soon（多久之后）、how far（多远） I don’t know how long we can keep a good memory. 我不知道我们能保持良好记忆力多久。 四、必考句型转换规则（特殊问句变宾语从句） 四步变法（万能步骤） 1. 找疑问词，直接保留，作连接词 2. 去掉助动词 do/does/did 3. 动词还原时态 4. 改为“疑问词+主+谓”陈述语序，句末变句号 例题演示： 特殊问句：How do you remember new words? 宾语从句：I want to know how you remember new words. 五、三大从句终极对比（单元必考辨析） 1. that从句：陈述句变来，无疑问含义，that可省（特殊情况不省） 2. if/whether从句：一般疑问句变来，表“是否” 3. wh-特殊疑问从句：特殊疑问句变来，有具体疑问信息，无that/if/whether 六、高频易错点（90%学生扣分点） 1. ❌ 语序错误：从句仍用疑问语序（can/will/do提前） 2. ❌ 画蛇添足：特殊疑问从句前多加 that/if/whether 3. ❌ 时态不倒退：主句过去式，从句时态不变 4. ❌ 多余助动词：从句里残留 do/does/did 5. ❌ 混淆how词组：how long/how often/how soon误用 七、单元万能写作句型 1.
