Conditional sentences. “If” clause: future tense, “result” clause: “Would”
Sentences expressing future tense are considered to be unreal or imaginative conditional sentences. These sentences express an action in the future that will only happen if a certain condition is fulfilled by that time. It is not known for sure whether or not the action will be fulfilled, but the condition seems realistic.
For example, reconsider the following sentences:
If you will only help me in the kitchen, I would cook your favorite meal tomorrow.
In this sentence, the speaker is making a deal with their speaker that they will receive their favorite home-cooked meal in exchange for their help in the kitchen. This will only happen if the listener helps in the kitchen. Since it depends on a condition, the sentence is considered unreal. The sentence would be a real condition only if the speaker is certain they will receive help.
