The Use of Zero Conditional Sentences
We use zero conditional sentences to describe habits and regular actions. In the if-clause usually the present simple or the present continuous tense is used.
Examples: 1. When Susan is feeling happy, she dances. — Когда Сьюзан чувствует себя счастливой, она танцует. 2. If I miss the train, I usually take a taxi. — Если я не успеваю на поезд, то я обычно беру такси.
We can also use zero conditionals to give instructions depending on certain conditions (the if-clause with the imperative mood).
Example: If you are free, come over for dinner. — Если вы свободны, приходите на обед.
