2、已经开走了.bythetime意思是“到…的时候”,相当于when,后接过去时的句子时,主语的谓语动词用过去完成时态.过去完成时态的用法：1、表示过去的过去，通常由by引导的短语做时间状语或者由by/when/before引导的从句做时间状语从句①Bytheendoflastyear,IhadlearnedaboutonethousandEnglishwords.②Bythetimehewastwenty,hehadwonabouttenmedals.③WhenIgotthere,theyhadalreadyleft

4、区别现在完成时表示的动作发生在过去，但侧重对现在产生的结果或造成的影响，与现在有关，其结构为“助动词have(has)+过去分词”；过去完成时则是一个相对的时态，它所表示的动作不仅发生在过去，更强调“过去的过去”，只有和过去某时或某动作相比较时，才用到它。本课出现的主要动词的过去式和过去分词ringrangrunggetgotgottengowentgoneleaveleftleftstartstartedstartedbewas/werebeentaketooktakenrunranrunwakewokewoken
