If-sentences: real vs. unreal

VerbsRule 7 of 10

The rule

For a real future, use the present after if and "will" in the other half: "If it rains, we will cancel." For an unreal or imagined case, use the past after if and "would": "If I had more time, I would travel." Keep "will" and "would" out of the if-part in these patterns; only fixed polite phrases like "if you would follow me" break that rule.
