Hello Jill, Hope I can help you here: -------------------------------------------------- Question 1: What does "back" mean in these two sentences? Could you please give me more similar examples? 1. Meanwhile, back in London, Palace Pictures was collapsing... 与此同时，伦敦的皇宫影业公司也正在分崩离析。 Back in Texas, we experience the hottest of summers. (Back in my hometown ( place of origin or first place I spoke about), we experience the hottest of summers). Back in my old neighborhood, we would play basketball until the late hours. (This means back in time and in a place I was before). 2.Later, back at home, the telephone rang. 随后，家里的电话响了。 (Home is your origin or it's the place you come from). Question 2: Can I use "Back in prison" to express the meaning that "When I was in prison"? (Yes, you could if the person already knows that you were in prison. Example: I went to prison in 1889. Back in prison, we would think of ways to spend our time.) Thanks for your help. -------------------------------------------------- Keep on learning! Regards, David
