I have seen many users of italki with Russian flag asked about 埃及， 沙漠，骆驼…… At first, I thought it's a same person who asked these question. For several times, I clearly remember I saw someone answered his/her question, and I saw a question in another day, when no one had answer him/her yet. I even thought I had traveled through time. I am curious is them example sentences in Chinese language textbook? What is the name of it?
