Immediate future: using be about to and Parallel verbs

(a) Ann’s bag are packed, and she is wearing her coat. She is about to leave for the airport.
(b) Shhh. The movie is about to begin
The idiom “be about to do something” expresses an activity that will happen in the immediate future, usually within minutes or seconds. In (a): Ann is going to leave sometime in the next few minutes.

Parallel verbs 

(a) Jim makes his bed and cleans up his room every morning.
Often a subject has two verbs that are connected by and. We say that the two verbs are parallel: v + and + v. makes and cleans = parallel verbs
(b) Ann is cooking dinner and (is) talking on the phone at the same time.
(c) I will stay home and (will) study tonight
(d) I am going to stay home and (am going to) study tonight.
It is not necessary to repeat a helping verb (an auxiliary verb) when two verbs are connected by and.
