I'm sorry I'm not from 'your elite of selected teachers'My sweet and respected teachers,
1 : ''She's busy with her studies''
2 : ''Find a girl of your same age''
3 : ''She asked me if I'd like to eat anything'' or ''She asked me if you'd like to eat anything'' (Both are correct. But 'I' refers to you,as the speaker of the sentence, and 'you' to other person).
4 : ''I'm improving spelling''
5 : ''I'll catch any of those boys''
6 : ''What should I use ''singular'' or ''plural'' after ''any''?please explain
You use plural forms in cases like this because you're referring to one random person within a group (in this case, a group of boys)
Note: I'd be happy if only selected teachers <moderatotrs> correct my sentences.
