语法讲解：时间状语从句的用法解析及练习
<p> 状语从句在复合句中作状语，其位置较灵活，可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号，放在句末时状语从句前面往往不用逗号)。根据状语从句的含义，状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结，希望可以帮助到同学们有一更深的理解。</p><p> 时间状语从句的引导词</p><p> <span word="when">when</span>, <span word="before">before</span>, <span word="after">after</span>, <span word="as">as</span>, <span word="while">while</span>, <span word="till">till</span>/<span word="until">until</span>, <span word="since">since</span>，<span word="whenever">whenever</span></p><p> 时间状语从句的用法</p><p> 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。</p><p> 1. <span word="when">when</span>、<span word="as">as</span>、<span word="while">while</span>引导的时间状语从句分析：</p><p> (1) <span word="when">when</span>引导时间状语从句时表示当的时候，<span word="when">when</span>既可以指时间段也可指时间点，从句中既可用延续性动词又可用非延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。</p><p> 注意体会如下例句：<span word="Ill">Ill</span> <span word="call">call</span> <span word="you">you</span> <span word="when">when</span> <span word="I">I</span> <span word="get">get</span> <span word="there">there</span>. 我一到那里就给你打电话。// <span word="When">When</span> <span word="the">the</span> <span word="wind">wind</span> <span word="blows">blows</span>, <span word="all">all</span> <span word="the">the</span> <span word="doors">doors</span> <span word="rattle">rattle</span>. 只要风一吹，这门就吱嘎作响。// <span word="He">He</span> <span word="stopped">stopped</span> <span word="trying">trying</span>, <span word="when">when</span> <span word="he">he</span> <span word="might">might</span> <span word="have">have</span> <span word="succeeded">succeeded</span> <span word="next">next</span> <span word="time">time</span>. 他不再试了，其实他可能下一次就成功。// <span word="When">When</span> <span word="I">I</span> <span word="came">came</span> <span word="home">home</span> <span word="my">my</span> <span word="wife">wife</span> <span word="was">was</span> <span word="cooking">cooking</span> <span word="dinner">dinner</span>. 我回家时，妻子在做晚饭。</p>
