zero conditional

zero conditional

1. use: it always happens

2. if + simple present,.....simple present

   • simple present,.....if + simple present

3. example:

   • if water reaches 100 degrees,it boils
     • people die if they don t eat

4. inversion:the 'if' in this conditional can usually be replaced by 'when' without changing the meaning

   • when water reaches 100 degrees,it boils
