B) Present Perfect Progressive

The present perfect progressive is the first grammar tense in the group of the perfect progressive tenses within the sixteen that there are in English and it’s going to be used to talk about an action that was carried into the past tense but that it had a continuity into the past itself and therefore we also have the certainty that the action keeps on being carried out into the present too. Grammatically we will have to use the auxiliary “have” or “has” followed by the participle been and finally the main verb in a gerund way (with the ending “ing” in all the verbs.)

Affirmative Way

Subject + have / has + been + verb in gerund + complement

Examples

• They have been organizing everything for Mary’s wedding
• We have been renewing all the furniture in our house
• He has been driving so fast lately and he might have an accident
• She has been taking care of her kids all the time

Negative way

Subject + haven’t / hasn’t + been + verb in gerund + complement

Examples:

• Helen hasn’t been getting good scores at school because she has been getting late
• They haven’t been getting on well lately due to some job problems
• He hasn’t been training for the next championship as it must be
• Karl and Sandy haven’t been asking for permission to their parents to go swimming
• You haven’t been doing what you were asked
