Как выбрать время

Present Simple используем для:

• привычек и регулярных действий: every day → He takes;
• фактов и законов: Water doesn’t boil at 80°C;
• расписаний: The bus leaves at 6:30 pm;
• глаголов состояния и мнения: like, think → doesn’t like, don’t think.

Present Continuous используем:

• для действия прямо сейчас: now, Be quiet → is sleeping, isn’t watching;
• для запланированного действия в ближайшем будущем: this weekend, next week → is visiting, are leaving;
• с always, если говорящий подчёркивает раздражающую привычку: He is always biting his nails.

Формулы

• Present Simple:
  he/she/it + глагол + s → takes, leaves
  do/does + not + глагол → doesn’t boil

• Present Continuous:
  am/is/are + глагол-ing → is sleeping, are leaving
