Like most subordinate clauses introduced by a conjunction, the conditional clause can either go before the main clause, or after it.he verb of the main clause is in the future tense with  will  (or sometimes another modal). The verb of the conditional clause is in the simple present tense. Occasionally, the open conditional statement describes one potential state of reality or circumstance which is dependent on another.
