Power outages in the neighborhood are delaying our release of Film Friday - we'll be releasing the show later tonight instead of in the early afternoon as usual. In the meantime, why not try your hand at today's Advanced HSK test. These exercises about as difficult as the Advanced HSK gets. Your challenge is to identify which section in a lengthy text has an error in grammar or word choice.If you do poorly and are new to these questions, don't feel badly, but do try to figure out why you've gotten the answers wrong since you will be tested on them in other sections as well. If you need help, feel free to ask questions either here in the discussion section or over email with email@example.com. And those of you who do well deserve a pat on the back: even native speakers have difficult with these sorts of questions.
