44、eft home.她想起她可能在离开家时没把门关上。(2)同位语从句的语气。在suggestion,advice,request,order等意为“建议,要求,命令”的名词后,同位语从句中的谓语动词通常用“should+动词原形”的虚拟语气结构,句中的should可以省略。如:The suggestion came from the chairman that the new rule(should)be adopted.主席提出建议,应采纳新规则。【活学活用】(1)I admired the fact that he would talk to students outside the cl
