Is it wrong to use the verb to walk in the progressive form?
I had to choose the correct verb in this exercise.
'Where are you walking/going to?' 'I am walking/going to my office.'
He likes walking/going.
He goes/walks a lot.
How often does your son go/walk there for the week-end?
"Where are you walking/going to?" is natural in AmE. The "to" is unnecessary, but you will hear it.
[AmE - not a teacher]
1: Why does he go?
2: I don't know. He likes going.
1: So how often does he go?
2: He goes a lot.
