This is a typical sentence using the be going to do sentence pattern, when changing from a positive sentence to a negative sentence, you only need to add not after the be verb. However, it should be mentioned that in the be going to do sentence spike posture type, try to avoid the two verbs go at the same time. The proper expression of the original sentence should be they're going skating。

do they go to work by bus?
Because a general interrogative sentence is a sentence that comes with yes or no. Its structure is: the verb be auxiliary verb modal verb + subject + other components.
So do they go to work by bus?Instead of how do they go to work?Because the latter is a special interrogative sentence.
They go to work by busInstead of yes.
Don't you know if I explain it that way?
-
do they go to work by bus ?.
When the predicate verb is an action verb or a substantial verb, do or does should be added before the subject, and the original verb will be restored to its original form.
Hope to help you.
