Объяснение:

• Present Perfect используется для действий, которые начались в прошлом и продолжаются до настоящего момента или для описания опыта, который влияет на текущее состояние (например, "have been," "have lost," "have taken").
• Present Continuous подходит для действий, которые происходят прямо сейчас или в процессе изменений (например, "am still working," "is doing," "are now living").
• Present Simple применяется для фактов или постоянных ситуаций (например, "know," "am happy").

Эти времена помогают передать разницу между текущими и законченными действиями, а также показать постоянные или временные состояния.
