When you hit the big two-zero, it's reasonable to stop and look back at all you've accomplished in life. And from our perspective it looks pretty good. Today marks the publication of our twentieth fill-in-the-blanks exercise, and the fiftieth sample test we've produced for students preparing for the first level of China's standard test in mandarin proficiency. That's more than 700 questions on the finer points of Chinese grammar and word usage at the beginner level alone. All available 24/7 from the comfort of your WiFi-enabled bathroom.

Our test for today focuses on verb complements. If you've been following us from the beginning and have already gone through our massive test archive, you've seen these before and shouldn't find this too challenging. If you haven't brace yourself though. Take a deep breathe, click through to the quiz section and ace this puppy. In the meanwhile I'll go chase those kids off my lawn again. They've taken to congregating there in the hopes of catching a glimpse of Apple and Echo.
