Давайте разберем этот текст и ответим на вопросы, используя правильные формы глаголов и временные конструкции.

1. Is Andy here? – I don’t know, I haven’t seen him today.
   Здесь используется Present Perfect (haven't seen), чтобы указать на то, что до настоящего времени я не видел Эндии.

2. Where are you going? – To the library. Would you like to borrow this magazine? – No, thanks. I have read it before.
   Вопрос о направлении требует использования Present Continuous (are going). "Would you like to borrow" – инфинитив. "I have read" также в Present Perfect, указывая на то, что действие произошло в прошлом и имеет значение для настоящего.

3. Betty’s bus arrives at 5 o’clock. I must go and meet her at the bus station.
   Здесь используется Present Simple (arrives) для описания расписания.

4. Have you seen my record book? I have been looking for it all morning.
   "Have you seen" – Present Perfect, "I have been looking" – Present Perfect Continuous, что показывает длительность действия.

5. Mike has been talking to his friend for an hour already.
   В этом предложении также используется Present Perfect Continuous (has been talking) для обозначения продолжительности.

9. They are playing football tonight.
   Present Continuous (are playing) указывает на запланированное действие.

10. Linda is disappointed. She has failed her test.
    Здесь Present Simple (is disappointed) описывает состояние, а Present Perfect (has failed) указывает на завершенное действие.
