&&&很多同学对英语复合句中的主、从句时态的一致性问题搞不清楚。今天，我们就来谈谈这个问题。相信同学们看了这篇文章之后，再遇到复合句中的主、从句的时态问题，就不会感到困难了。
&&主从复合句中时态的一致主要有以下几种情况：
&&一、在以when，after，as&soon&as等引导的时间状语从句以及以if，unless等引导的条件状语从句中，如果主句是一般将来时，从句则用一般现在时。例如：
&&I\'ll&tell&her&the&good&news&when&she&comes&back.当她回来的时候，我将把这个好消息告诉她。
&&If&it&doesn\'t&rain,&he&will&come&here&on&time.如果不下雨，他会按时来这儿的。
&&二、在含有宾语从句的主从复合句中，当主句的谓语动词为过去时态时，从句须用表示过去的某种时态。例如：
&&He&asked&when&they&would&go&to&the&party.他问他们什么时候将去参加聚会。
&&Miss&Green&said&she&had&been&to&Beijing&before.格林小姐说她以前曾经去过北京。
&&三、在宾语从句中，当主句的时态为一般现在时、现在进行时、现在完成时等时态时，后面从句时态不受主句限制，可根据情况，选用各种适合的时态。例如：
&&Do&you&know&when&we\'ll&have&a&football&match?你知道我们什么时候举行足球赛吗？
&&You&know&he&has&gone&to&Shanghai.你知道他已去上海了。
&&四、当宾语从句表述的是客观事实、科学真理、现在的习惯动作以及格言等时，其时态不受主句限制，而用一般现在时。例如：
&&The&teacher&told&us&that&light&travels&faster&than&sound.老师告诉我们光速比音速要快。
&&When&I&was&a&student,&my&teacher&often&told&us&that&time&and&tide&wait&for&no&man.当我还是学生的时候，老师常常告诉我们，岁月不等人。
&&五、在&since＋点时间&句型中，主句通常用现在完成时，从句用一般过去时。例如：
&&He&has&worked&at&the&factory&since&he&came&here.自从他来到这儿，他就一直在这家工厂上班。
&&另外，在句型&It\'s+段时间＋since＋从句&中，since后面的从句要用一般过去时。例如：
&&It\'s&a&long&time&since&we&met&last.自从我们上次见面以来已经有好长时间了。
&&六、在复合句中，如果主、从句表示的动作或状态都发生在过去，而且有先后，则在先的用过去完成时，在后的用一般过去时。例如：
&&When&he&got&there,&the&train&had&left.当他到那儿的时候，火车已经开了。
&&He&said&he&had&visited&the&school&before.他说他以前参观过那所学校。
