．——There is a lot of smoke coming out of the teaching-building there．

——Really? It be a fire, most probably．

A．can B．ought to C．have to D．must

为什么选ought to不选can。不是表示猜测吗？

有most probably,表明肯定性很大，按预期强弱，这四个由强到弱应该是must ,ought to, have to, can.
但是用must，表示一定，后面的most p就不用了，所以不选。have to 的意思不对，一般用法，sb has/have to do.或 it has to be like this仅此两用法。can 没有ought to语气强。所以综上，选ought

can表示猜测用在否定句中

can表示可能可以表示还未发生的事有将来的意思而题目是这儿有…………是已经发生的事所以选ought to
