zero and 1st conditional

zero and 1st conditional

1. 1st conditional

   • It is used to refer to the present or future when the situation is real
   • The type 1 conditional refers to a possible condition and its probable outcome
   • In these sentences, the "if" clause takes the "simple present" and the main proposition the "simple future"

2. zero

   • It is used when the time we are referring to is now or always and the situation is real and possible.
   • In conditional sentences of type 0, the term "if" can normally be replaced by "when" without changing the meaning.
   • The verb tense of both propositions is the "simple present"
