5 Euros to whoever can give me an sentence example of the present perfect continuous tense using the verb "to walk".

How can I teach all this stuff if I have no clue what it is? It´s a question that young, lazy English teachers like myself have probably been asking since the dawn of time (or at least like ´95 or something).

I guess I am going to have to break down and learn it. But am I the only one that cringes when thinking about past participles and the future perfect tense? I had to look up the definition of "adverb" the other day. I don´t know what´s worse, the fact that I had to look it up or the fact that as I sit here typing this, I can´t remember the answer. Quickly, someone tell me when a sentence can end with a preposition....

And, to make matters worse, the Spanish learn by "grammar". That is how they learn their language and how they like to learn English, so a common question could be "well, what is the past particple of that verb"? Talk about getting caught with your pants down...I was just glad they asked my friend, not me. But he was fucked.
