A.Because B.Although C.If D.Unless 答案：B 解析：句意为“尽管雨下得很大，我们仍然准时到达了车站”。前后句为让步关系，“虽然尽管”用 although,且不能与but连用，符合让步状语从句用法。 真题2（语法填空）： You will succeed you keep working hard.(填引导词) 答案：if/as long as 解析：句意为“如果你/只要你继续努力，你就会成功”。表示条件关系，“如果”用f或“只要”用 as long as,符合条件状语从句“主将从现”规则。 考法二：状语从句连接词辨析与时态一致性综合判断 9年级专项复习教科版（五四制） 【状语从句专练】 知识点全解 核心：结合不同类型状语从句的连接词用法（如时间、条件、让步等），同时依据从句时态规则（如 主将从现、主过从过等)，判断句子中连接词选择及动词时态的正确性 真题1（单项选择)： it rains tomorrow.we stay at home A.If,will B.Unless,will C.As,do D.Though,are going to 答案：A 解析：根据句意“如果明天下雨，我们就待在家里”，此处为条件状语从句，应用“主将从现”规 则，主句用一般将来时，从句用一般现在时，if符合语境：unless表示“除非”，代入后逻辑不符： s引导时间或原因状语从句，此处不适用：though引导让步状语从句，与句意不符。 真题2（句子改错）： Although he is very busy,but he always helps me with my English. 答案：去掉but 解析：though/although引导让步状语从句时，不能与but连用，可保留but去掉Although,或直接 去掉but,此处修改为“Although he is very busy,he always helps me with my English.” 考法三：状语从句连接词综合辨析与时态应用 核心：结合语境区分不同类型状语从句的连接词，掌握？主将从现”等时态规则及易混点（如 when/while/as、if/unless、so that表目的/结果的区别) 真题1（单项选择)： the teacher came in,we were talking loudly.We all stopped at once. A When B While CAs D Since 答案：A 解析：句中'came in'”为短暂性动词，强调”老师进来时（动作发生）我们正在说话'，主从句动作 先后发生，符合when可接短暂性动词且表动作先后的用法：while需接延续性动词，as强调”一 边…一边”，since表”既然”，均不符合语境。 真题2（语法填空)： You will not improve your English you practice reading every day.My teacher always says practice makes perfect. 答案：unless 解析：句意”你不会提高英语 你每天练习阅读”，结合语境可知后句是前句的否定条件，即” 如果不练习就不会提高’，unless表示”除非；如果不’，相当于”if...not'',符合条件状语从句的逻辑： 且主句为将来时，从句用一般现在时”practice'”,符合”主将从现”规则。 解题小妙招 9年级专项复习教科版（五四制） 【状语从句专练】知识点全解 引导词辨析妙招 引导词选要看关系，时间条件让步析： because表原因，although让步不与but遇： f条件主将从现，so后形副such名； 语境含义是关键，逻辑通顺才可以。 真题演练 演练一：单项选择试题 1.We will go for a picnic the weather is fine tomorrow.
