【解析】
试题分析：此题重点考查被动语态，由于主语是动作的承受者，该句要用被动语态，排除A、C；根据句意：“每天一定要浇花，否则他们会死掉”B答案语气太委婉，因此要用must be+过去分词，故选D

（1）现在时：无区别，但后者不常用。 （2）完成时;can没有完成时，此时要用have（has,had）been able to。 （3）将来时：can没有将来时，要用will be able to。 （4）过去时：could表示一般能力，was/were able to 表示在具体场合通过努力成功做成某事的能力。 二、may 和might 1、may的用法 （1）表示询问或说明一件事可不可以做。 （2）表示一件事或许会发生或某种情况可能会存在，通常用在肯定句和否定句中。 注意：表示可能性时，can’t语气强，表示“不可能”，may not语气弱，表示“可能不”。 2、might的用法 （1）表示询问或允许，指的是过去时间。 （2）表示可能发生的事，可以指过去时间，也可以指现在时间，语气更加不肯定，可能性比may小一些。 3、may与might的特殊用法 （1）“may+主语+动词原形”表示祝愿。 （2）“may/ might well+动词原形”表示（完全）能，很可能。 （3）“may/ might as well+动词原形”表示最好，满可以，倒不如。 （4）may be 是“情态动词+系动词be”结构，表示“可能有，可能在”，否定式为may not be。 maybe是一个词，为副词，意为“大概，或许，可能”，在句中作状语。
