Re: Please help me
Lisa, it would be helpful if you gave your threads more useful titles, like any + singular noun.
I would like to add the comment that the normal construction doesn't use the singular, but it's possible in emphatic situations.
A: There's a spider! Squash it!
B: Spiders are beneficial, so leave it alone. Besides, I don't see a spider.
A: No, it's right there. Eeek! Do something!
B: I don't see a spider! There is no spider!
A: It's right here, between us! (running away)
B: For heaven's sake, there isn't any spider there!
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
