I need your help urgently, please!!!

Hi, I am an English teacher, I am 40 years old.

I am working with my Intermediate students now using Face2Face Intermediate teaching material. I find it quite useful, but for one thing.

Intermediate Work Book Unit 1A Be happy, Exercise 2b (make questions) page 5
b) Have you been clubbing in the last month?

Why Present Perfect Continuous is used speaking about the past (last month)? I have never ever come across with such usage of Present Perfect Continuous Tense, please, explain me the rule, since I need it before 10 Feb 2013 to explain it to my students,

thank you very much,

It is 'in the last month' - i.e., in the thirty or so days leading up to the moment of speaking.

Feeling chirpy to have learnt, again, something new I hope this question of mine is related to the post above!

Is there such a difference between 'during next week', and 'during the next week' with one of them, perhaps, meaning 'during the seven days from now', and the other one meaning 'during the seven days starting from the coming Saturday'?
