Use this speaking activity for reviewing adverbs of frequency: always, usually, sometimes, rarely. Use after an introduction or review of these adverbs. Split Ss into pairs or small groups and ask each other the questions. I usually then do another follow-up activity where I tape adverbs around the wall, read out sentences (i.e. I drink alcohol) and the Ss go to the place which describes how often they do something. (i.e. I usually drink alcohol.) Works great!
