Как выбирать время

• Present Simple — постоянный факт, привычка или состояние:
  he is at work, nobody answers, they want to rest.
• Present Continuous — действие происходит сейчас или прямо в процессе:
  are you waiting, is snowing, is still sewing, is examining.
• Present Perfect — действие завершилось к настоящему моменту, важен результат:
  has just finished, has not come yet, has torn up.
  Также с глаголами состояния: have always been, have known.
• Present Perfect Continuous — действие началось раньше и длится до сих пор, важна длительность:
  have been standing for fifteen minutes, has been blowing since morning, have been rewriting for half an hour.

Проверка

Главные подсказки в задании: now / at the moment → Present Continuous; just / already / yet → Present Perfect; for / since / all day → Present Perfect Continuous, если действие длится. С глаголами be, know, want обычно не используем Continuous, поэтому в №12 — have always been, have known.
