题目内容：

Tom often __goes__(go) to school on foot.But today is rain.He __is going to go__ (go) to school by bike.这里is going to go可以改为went 或是will

优质解答

这里不能用is going to go必须改为will
be going to do 不能说be going to go (重复了go,不对）又如I'm going to Qingdao today
不能用went.如果是today was rainy,he went to school by bike 就对了
