Давайте разберем вашу задачу, где необходимо заменить инфинитивы на соответствующие формы настоящего времени. Я буду объяснять каждый шаг по порядку.

1. I am here too long. I want to get away.

   • "to be" меняется на "am" (настоящее время, 1-е лицо), "to want" становится "want".

2. What does he do for a living? He sings and plays the guitar.

   • Здесь "to do" преобразуется в "does" (первый вопрос), "to sing" и "to play" становятся "sings" и "plays" соответственно.

3. He plays for his friends or just for grumbling (чтобы не повторять "to think").

   • "to play" меняется на "plays".

4. Where does he get money? I don’t know... from Tommy? Is he abroad yet?

   • Здесь "to be" меняется на "is" в вопросе, "to get" на "get", и добавляем "don’t" к "know" для отрицательной формы.

5. No, he hasn't arrived yet. Mr. Smith is coming on Saturday.

   • "to arrive" становится "hasn't arrived". И "to be" — "is".

6. The old man has been sitting in front of the fire since dinner-time.

   • "to sit" здесь используется в форме "has been sitting" для обозначения действий, происходящих в течение времени.

7. I haven't had a holiday for two years.

   • "to have" превращается в "haven't had".

8. I have been trying all the afternoon to get a minute alone with you.

   • Используем "have been trying" для настоящего продолженного времени.

9. We are renting two rooms in Dabney Street and we are furnishing them now.

   • "to take" меняется на "are renting", "to furnish" на "are furnishing".

10. "What do you write him about?" she asked looking over my shoulder.

    • "to write" меняется на "do you write".

11. I am reading the book you are holding.

    • Здесь "to read" становится "am reading", "to hold" — "are holding".

12. You always forget something.

    • "to forget" становится "forget".

13. I have grown too fat.

    • "to grow" меняется на "have grown".
