Hi Pelin, 1. Yes that sentence structure is correct. 2. I would not use that particular structure - its a bit formal. Are you looking for British or American English. I would remove the up". I.e. Why are you closing so early? OR Why are you closing the store so early? 3. Correct 4. Its ok, but its passive voice. Try : The list has everything I need written on it. Think SVO (subject , verb , object). 5. These are incomplete sentences, by themselves. I would need to better understand the context, what is written/says on "it". I.e. The instructions are written on the paper. Hope this helps
