Hi Believer
Maybe making the wording more specific will also help you understand.
Let's say that the following sentences describe your habits factually (i.e. the sentences tell you what is "real"):
1. I play chess one hour a day.
2. I listen to pop music four hours a day.
If the sentences above are "real", then the following sentences are not "real" (i.e. they are not factual statements about your habits):
1a. I play chess two hours a day.
2a. I listen to pop music three hours a day.
Sentences 1a and 2a are simply two untrue statements. They are not yet part of a single conditional sentence.
An IF-sentence talks about a condition, and then states the result if the condition is met.
You can present sentence 2 as an "unreal" condition this way:
- "If I listened to pop music three hours a day, ..."
To finish your IF-sentence, you then say what the result of fulfilling the "unreal" condition would be:
- "... I would play chess two hours a day."
Your original sentence was simply less specific about the amounts of time spent on each activity, but the concept of "real" vs "unreal" is the same:
