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". 14. You **have waited** long? - Yes, I **have been standing** here for more than half an hour. - Здесь "to wait" становится "have waited", "to stand" — "have been standing". 15.
