What's your favorite magazine ?   Off hand , I'd say the Reader's Digests is my favorite .   What kind of magazine is it ?   It's instructive and inspiring .   Really ? It is a weekly , isn't it ?   No , it's a semimonthly .   Does it enjoy popularity among the young generation ?   Yes , it's so popular that it's sold out as soon as it reaches the bookstores .   Oh , I think I should try to read one .
