Betty: Oh, what a funny photo! When did you take it?
Ben: Last year, at my school’s New Year Eve party.
Betty: Who is playing the guitar?
Ben: Duncan. He often plays the guitar at the parties. He can play the guitar very well.
Betty: What are the girls doing?
Ben: They are singing an old English song. The girls perform in our School Theatre. Look! Jim and Ann are dancing. They are good dancers. They dance in our School Dancing Club.
Betty: I see. And what do you do after classes?
Ben: I like taking photos. Do you like my photo?
Betty: It’s great.

Теперь разберём, почему используются именно такие времена.

1. Who is playing the guitar? – Present Continuous
   Вопрос про действие, которое происходит прямо на фото / в данный момент. Поэтому используем форму is playing:
   who + is + playing.

2. He often plays the guitar at the parties. – Present Simple
   Здесь говорится о привычке, регулярном действии. Есть слово-показатель often, поэтому ставим plays (he plays).

3. What are the girls doing? – Present Continuous
   Вопрос о том, что девочки делают сейчас (на фото). Поэтому:
   are + doing → are doing.

4. They are singing an old English song. – Present Continuous
   Продолжающееся действие в момент фотографии:
   are + singing → are singing.

5. The girls perform in our School Theatre. – Present Simple
   Это факт о них, их постоянная деятельность. Поэтому perform (Present Simple для общего факта, привычного действия).

6. Look! Jim and Ann are dancing. – Present Continuous
   Слово Look! почти всегда сигнализирует о действии, происходящем прямо сейчас. Поэтому are dancing.

7. They dance in our School Dancing Club. – Present Simple
   Это уже не про «сейчас», а про постоянное занятие, кружок, клуб. Поэтому dance.

8. What do you do after classes? – Present Simple
   Вопрос о регулярных действиях после уроков. Поэтому do you do.

9. I like taking photos. – Present Simple
   Постоянное предпочтение, увлечение – like.

10. Do you like my photo? – Present Simple
    Вопрос о мнении, отношении – тоже Present Simple: do you like.

Так в этом диалоге Present Continuous показывает действия «на картинке / сейчас», а Present Simple – привычки, факты и постоянные занятия.
