解析：
【小题1】根据下文时间状语从句，当我昨晚给他们打电话时，可知主句为过去进行时态，填were having。
【小题2】短语look forward to盼望。其中to为介词，后面接名词或者动名词，故填receiving。
【小题3】句意：昨天李博士首先被要求介绍他去非洲的旅行。可知句子为过去时态，李博士是被要求的对象，用被动语态，故填was asked。
【小题4】结合语境可知下文描述的是将要发生的动作，故用将来时态，填will get。
【小题5】Would you please后接动词原形，表示请求别人做什么，其否定形式时在后面，动词前面加not，故填not disturb。
【小题6】情态动词后面的动词一般用原形，this passage是动作对象，故用被动语态，填be divide。
【小题7】句意：既然我们现在已经完成了作业。让我们休息一下吧！可知前文描述的是现在已经完成的动作，故用现在完成时态，主语是we，故填have done。
【小题8】结合语境可知下文描述是客观现实，故用一般现在时态，主语colour为抽象名词不可数，故谓语动词用单数，填relaxes。
