D .can表示一种能力,表示会做,与他可能采用其他的方式去做,语气上矛盾
如果他们做这个工作，他将来某天可能就会做它。
这个题从搭配上看的话应该只有 be to 合理。
如果要接should will can 的话，应该去掉to ,
be to 有将做什么的意思。而且在if的从句中应该 不能用will,
所以用了be to 来表示将来。
你好:
be to do sth 意思是"将要做某事"
翻译; 如果他们要做这份工作, 他可以通过其他的方法做到
were to do 是指的过去的时间里要去做某事
if they were to do this work,he might do it some other way
如果他们去做这件事的话，他可能会用另外一种方式。
另外，can是情态动词，后面的动词要用动词原型。
to是介词
句子的构成：主语+谓语（动词）+宾语
此句中，they是主语，后面要跟动词做谓语，不能直接跟to，can是情态动词也不能独立做谓语，所以这里必须增加一个be动词，be to do是固定形式，表示将来时。
