Tense in predictive conditional sentences

Predictive conditional sentences are used to predict the future or to express future plans or possibilities. To form a predictive sentence, use a present-tense verb in the subordinate clause (the if or unless clause); in the independent clause, use the modal will, can, may, should, or might plus the base form of the verb.

Example sentence: If you practice regularly, your tennis game should improve. Explanation: The if clause is “If you practice regularly.” The result clause is “your tennis game should improve.”

TIP:In all types of conditional sentences (factual, predictive, and speculative), if or unless clauses do not use the modal verb will.

Example sentence with editing. Original sentence: If Jenna will pass her history test, she will graduate this year. Revised sentence: If Jenna passes her history test, she will graduate this year. Explanation: The verb “will pass” is changed to “passes.”
