【点睛】shall的用法。
1. shall作为助动词，一般用于第一人称Ⅰ和We，表示一个将来的动作，构成将来时态。
shall后面接动词原形。

如：Shall we begin our lesson? When shall he be able to leave the hospital?4. shall用于第二、第三人称，表示说话人给对方命令、警告、允诺或威胁。

句意：如果愤怒的女乘客和巴士司机保持冷静，这起导致15人死亡的事故本来是可以避免的。
could have done“本来能做而没有做”，且句子主语The accident和谓语动词avoid之间是被动关系，结合句意可知答案为D。
【点睛】情态动词+ have done结构：1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测，语气比较坚定，通常只用于肯定句。
如：It must have rained last night,for the ground is wet.2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定。
can和could一般用于否定句和疑问句，could的语气较can弱。
如：He can't have finished the work so soon.3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测，might的语气比may弱一点。
这种结构主要用于肯定句和否定句，疑问句改用can或could。
如：They may not have known it beforehand.4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情，或过去做某事纯属多余。
