I have made up three examples below.
(1) If you have time, would you go fishing with me?
(2) Is there a situation in which you would fight a poisonous snake?
(3) I say to John,"While I work on my project in my bedroom, if someone made a lot of noise, would you quiet them down for me?"
Are my examples OK with two different tenses each? Thanks you for your help.
Hi, Ansonman: Sentences (1) are (2) are OK. Please let me know if you are perplexed as to why they are correct. Sentence (3), however, does not work well. It would be better (though still not a wonderful sentence) if you used the progressive in the "while"-clause: "While I am working on my project in my bedroom . . . ." Also, I would prefer "makes" in the "if"-clause and "will" in the main clause of (3), but it is not incorrect to use "made" and "would."
