May I ask you to check if the informations given on webside "matichia" suggested are correct? I mean the part about usage of will and would after if, sentences: (7) - (12). Also if the sentence (10) is really related to 1st conditional.
The grammar on this site a.k, is not very good, and the information isn't correct. It even had me questioning my use of Grammar!
" If you will cook the fish, I shall prepare salad".
It should be " If you cook the fish, I will/shall prepare salad.
" If you would answer the phone, I shall have some rest"
This doesn't make sense. What i would say is:
" If you could/can answer the phone, then i can have a rest" OR " Would you answer the phone? Then i can have a rest.
" If she will keep on attending my classes, i will be able to teach her something"
This should be:
" If she keeps on attending my classes, i will be able to teach her something.
" If she would admit you were wrong that, I would admire her"
I think this should be interpreted as:
" If she would admit that you were wrong,I would admire her"
" If only it would stop snowing,I could go for a fighting"
Not much sense here! My example:
" If only it would stop snowing, then i could go for a walk"
" If you ( will ) close the door, we shall be able to watch tv"
I would say:
" If you close the door, we can watch tv." OR " If you close the door, we will be able to watch tv"
a.k I have tried to stick as close to the original sentence and Grammar as possible, but i don't think these are particularly good examples.
What may be grammatically correct, is not necessarily what a native speaker would say, as i'm sure you are aware.
I would say: " If she would just admit that you were wrong, then i would admire her for that.
Hope this helps a bit, and i haven't confused you too much!
