✔ 最佳答案
"Has" is used to form the Perfect Tenses, eg:-He has finished repairing (gerund) 3 cars. Has he finished his 10 mins. break?
The Present Perfect Continuous Tense:-
The present participle;
Express the duration of an action up to the present time.
The action is still continuing at the moment of speaking.
May continue into the future,eg:-
Steven has been repairing 3 cars plus 10 mins. break for 1 1/2 hrs.(and is still repairing.)
Or ---------since 09:00.
This tense, and the other Perfect Continuous Tenses, are particularly associated with the words "for" and "since".and is correct.

Steven has been repairing cars for a period of time. If you just said "Steven has been repairing cars." that will be a fragmented sentence. You have to state how long after he has been doing this activity and connect them together with the preposition "for." For example, Steven has been repairing cars for three hours.
