Conditional Clauses

Правило для 1st conditional:
Данное предложение относится к первому типу условных предложений (1st Conditional). Такие предложения выражают реальное условие: если будет одно, то будет и второе. Предложения состоят из двух частей: условие (начинается с If, время Present Simple) и следствие/результат (время Future Simple).

Если перестанет идти дождь, мы поиграем в теннис.
Условие и результат в предложении могут стоять в любом порядке.

Правило для 2nd Conditional:
Данное предложение относится ко второму типу условных предложений (2nd Conditional). Такие предложения описывают воображаемые ситуации, которые противоречат реальности. Очень маловероятно, что они произойдут. Предложения состоят из двух частей: возможное условие (начинается с If, время Past Simple) и возможный результат (время Future in the past = would + инфинитив глагола без to/could/might).

Условие и результат в предложении могут стоять в любом порядке.

Правило для 3rd Conditional:
Данное предложение относится к третьему типу условных предложений (3rd Conditional). В этих предложениях условие относится к прошедшему времени и не может быть выполнено никаким образом. Предложение состоит из двух частей: условие в прошлом (начинается с If, время Past Perfect) и неосуществленный результат (время Future Perfect in the past = would + have + 3-я форма глагола).
If I had known about your problems, I would have helped you.
