Question

Since when ________ the boys __________ the match? (play) fill in the blanks with present perfect continous form of the verb given in brackets.​

Answer 1

Answer:

have, been playing

Explanation:

'Since when have the boys been playing the match?' will be the complete sentence.

Following is the general method used for present perfect continuous tense.

Have/Has + Subject + been + Verb-ing + Object
Since when have the boys been playing the match

So, here, the subject is underlined i.e., 'boys' and the object is underlined, 'match'. Have, been and -ing after the verb is used because of the sentence's present perfect continuous tense.
