Answer:
- There have been a lot of good programs on TV recently, haven't there?
- Yes, there have been.
Step-by-step explanation:
In this conversation, the first speaker is stating that there have been a lot of good programs on TV recently. They are asking the second speaker if they agree or if they have noticed the same thing. The second speaker responds with "Yes, there have been," indicating that they also agree with the statement.
The verb "have been" is used in this conversation to show that the action of having good programs on TV has been happening in the past. It is a present perfect tense, which is used to describe actions or situations that started in the past and continue up to the present moment. In this case, the action of having good programs on TV started in the past and is still happening. The auxiliary verb "have" is used with the pronoun "there" to form the present perfect tense. The pronoun "there" is used to refer to the existence of something or someone.
The second speaker's response confirms the first speaker's statement by using the same verb tense and the pronoun "there." They are acknowledging that there have indeed been a lot of good programs on TV recently.
Overall, this conversation demonstrates agreement between the speakers about the presence of good programs on TV and their use of the present perfect tense to describe this ongoing situation.
