if it's rainy or snowy

[hirashin]

Dear, native English speakers,
I am marking examination papers of Eigo Hyougen (Lit. English Expressions) now.
I come across a lot of unfamiliar expressions my students use.
Since I don't know much about English, I often can't judge if they are correct
or used. Would you help me?

Q1 I think (a) would be correct. But how about the others?
(a) The students come here whether it rains or snows.
(b) The students come here whether it's rainy or snowy.
(c) The students come here whether rainy or snowy.
(d) The students come here whether rain or snow.
(e) The students come here if it rains or snows.
(f) The students come here if it's rainy or snowy.
(g) The students come here if rainy or snowy.
(h) The students come here if rain or snow.
(i) The students come here rainy or snowy.
(j) The students come here rain or snow.

Q2 I think (a) would be right. But how about the others?
(a) Could you help me with the cooking?
(b) Could you help me do the cooking?
(c) Could you help me doing the cooking?

Q3 I think (a) would be all right. But how about the others?
(a) I go to the movies once or twice a month.
(b) I go to the movies once or twice every month.
(c) I go to the movies once or twice in a month.

Q4 I think (a) would be all right. But how about (b)?
(a) I sometimes watch DVDs in my spare/free time.
(b) I sometimes watch DVDs during my spare/free time.

Thanks in advance.

Hmmm even for native speaker, it's tough to know what is correct vs what sounds correct. Anyway here are my opinions.

(a) The students come here whether it rains or snows.
Good.

(b) The students come here whether it's rainy or snowy.
Good.

(c) The students come here whether rainy or snowy.
(d) The students come here whether rain or snow.
They don't sound too bad actually but I think it's not correct without the "it's."

(e) The students come here if it rains or snows.
(f) The students come here if it's rainy or snowy.
(g) The students come here if rainy or snowy.
(h) The students come here if rain or snow.
(k) The students come here if it's raining or snowing
I think it's wrong unless you say "even if." These imply that the students don't come when the weather is nice. As if they are going to a special place for bad weather only.

(i) The students come here rainy or snowy.
I think this is grammatically incorrect. In any case it sounds wrong to me. Plus it has the same problem as above.

(j) The students come here rain or snow.
I think this is grammatically incorrect. But not sure... there is a common phrase in English of "rain or shine." You can say "The students come here rain or shine" and it sounds natural to me.

(a) Could you help me with the cooking?
Perfect.

(b) Could you help me do the cooking?
Good.

(c) Could you help me doing the cooking?
Incorrect.

(a) I go to the movies once or twice a month.
(b) I go to the movies once or twice every month.
Perfect.

(c) I go to the movies once or twice in a month.
(e) I go to the movies one or two times in a month.
It sounds incorrect to me (but not terrible).

(a) I sometimes watch DVDs in my spare/free time.
(b) I sometimes watch DVDs during my spare/free time.
(d) I go to the movies one or two times a month.
(f) I go to the movies one or two times every month.
Perfect.

Thank you very much for your help, mdchachi. It's a great help.

Thanks for your thanks. BTW there's a thank you icon you can click on posts so you don't necessarily have to write "thank you" all the time.

I thought the same thing as md with Q1. Are they supposed to just make sense gramatically or are they meant to express a certain idea?
