With the First Conditional we are thinking about the future, and talking about a condition that is likely to happen and the possible result of this condition.
There is always a very real chance that the condition will happen.
For example, you get up in the morning and plan to go for a run, but the sky is getting cloudy. It’s not raining right now, but you think it might rain later. What will you do? If it rains, I will stay at home.
We use the Present Simple tense to talk about the condition. We use will + base verb or modal + base verb or imperative to talk about the result.
We don’t usuallyuse “will” or “won’t” in the “if” clause.
There are four basic English conditionals that we use to express possible or imaginary situations: Zero, First, Second, and Third.
Conditional sentences contain two clauses: the “if” (condition) clause, and the “result” clause. All conditionals have two easy, possible structures and either structure can be used without changing the meaning. We can put the “if” clause first, or the “result” first. Note that we only use a comma when the “if” clause come first.
For example: If a certain condition is true, then a specific result happens.
x = 10,
2x = 20
For example: A specific result happensif a certain condition is true.
2x = 20
x = 10
