Conditionals in English


Conditionals or 'if clauses' describe the result of something that might happen (in the present or future) or might have happened but didn't (in the past) . 
There are four kinds of conditional structure:
  • The Zero Conditional: it expresses what always happens if or when a certain action takes place. 
    (if + present simple, ... present simple)
    If you heat water to 100 degrees, it boils.

  • The First Conditional:  We use the first conditional to talk about something that will happen (the result)if a particular condition (which is likely to happen) is met. 
    (if + present simple, ... will + infinitive)
    If it rains tomorrow, we'll go to the cinema.
