核心：根据主从句动作的时间关系（同时发生/先后发生）及动作性质（延续性/短暂性），选择正确 的连接词when或while 真题1（语法填空）： _my mother was cooking,I was doing my homework 答案：While 解析：从句'my mother was cooking”和主句'I was doing my homework'均为过去进行时，表示两个 延续性动作同时发生，故用while引导时间状语从句。 真题2（完形填空)： I was walking in the park I met an old friend. A.when B.while C.until D.as soon as 答案：A 解析：主句I was walking'”为过去进行时（延续性动作），从句'I met an old friend''为一般过去时 (短暂性动作)，表示主句动作进行过程中突然发生另一个动作，用whn引导时间状语从句。 考法二：状语从句连接词与时态综合运用 核心：结合语境判断状语从句类型，选择正确连接词并匹配时态规则（如主将从现、主过从过） 真题1（语法填空)： I_(call)you as soon as I(arrive)at the station tomorrow. 答案：will call arrive 解析：as soon as引导时间状语从句，遵循'主将从现”原则：主句用一般将来时will call,从句用 一般现在时arrive表将来。 真题2（单项选择)： _it rains this weekend,westay at home. A.Unless will B.If will C.Though would D.As would 答案：B 解析：if引导条件状语从句，”主将从现”规则下主句用will stay:unless表否定条件与句意矛盾， 6 高中沪外版 【句法专版】 状语从句系统讲解 though/as不表条件，故排除A/CD。 考法三：状语从句连接词辨析及用法综合运用 核心：结合语境区分不同类型状语从句的连接词，掌握时间、条件、目的与结果状语从句的关键用 法及易错点 真题1（单项选择）： Tom studied hard he could pass the final exam. A.so that B.such that C.so.that D.even if 答案：A 解析：从句“he could pass the final exam”含情态动词could,表目的“为了通过考试”，应用so that 引导目的状语从句。such that无此结构，so…that表结果，even if表让步，均不符合语境。 真题2（语法填空）： She didn't go to bedshe finished her homework last night. 答案：until 解析：“didn’t go to bed”为否定句，结合语境“直到完成作业才睡觉”，应用until引导时间状语 从句，表“直到…才”，符合“否定句+ntil+从句”结构。 解题小妙招 状语从句解题妙招 when/while分动作，延续同时用while,延续突遇短暂用when: 时态匹配看连接，主将从现是规则，if/as soon as要遵守： 从句类型辨关系，让步转折用hough,假设条件if来帮： 目的结果看so that,目的有情态，结果so.that: 连接词义先辨析，时态一致要牢记，综合应用没问题。 真题演练 演练一：单项选择试题（共10题) 1.We will have a picnic in the parkthe weather is fine tomorrow.
