First Conditional Error Correction

This first conditional error correction exercise helps you catch the mistakes learners make most often with real future possibilities. The biggest problem is usually putting will after if, but learners also mix first conditional with the zero conditional, forget the present simple in the if-clause, or build the main clause with the wrong future form.

Wrong: "If Emma will see Jack tonight, she'll tell him." Correct: "If Emma sees Jack tonight, she'll tell him."
Wrong: "If the shop closes early, we take the train home." Correct: "If the shop closes early, we will take the train home."

It also trains smaller proofreading details that often get missed in fast reading: third-person singular forms like doesn't, is, and saves, plus the base verb after will in result clauses. That matters because many learners know the rule in theory but still miss the exact word that makes the sentence wrong.

Because you edit the wrong chunk inside full sentences, this route trains quick proofreading and rule-checking instead of simple gap-fill production. Some sentences are already correct, so you also practise not over-correcting valid first-conditional patterns with might, can, or an imperative main clause.
