There are some mistakes. ※If you want to ask someone(including me) to correct them, post this entry to http://www.italki.com/entries/japanese .

1. What do you have at your school? ( I'm guessing that the question is trying to pursue some distinct or unique feature of the school) 2. What's at the department store? 3. ?? Confused with the Japanese. I'm guessing it's このきょうしつにだれがいますか　　Who's in the classroom? 4. What's at the zoo? ( What can you find at the zoo?) 5. The Japanese bit is a little off. おんがく　は　何　を　ききますか。 Good Job!!
