叙述过去的事情的过程中,描述一般事实,用什么时态?
整体是在叙述过去的事情,但其中某句话是描述一般事实,这时该用什么时态?　　　　比如,叙述过去一次逛公园的经历：　　Five days ago, I went to the park with Alice. It was a nice day. Alice phoned me and invited me to go to the park for a walk. Alice [was/is] a good friend of mine. She [was/is] a beautiful girl. How could I refuse such an invitation from a beauty? So I accepted it immediately.　　Alice这块都是一般事实,一直存在着的事实,并非只存在于“逛公园的时候”.该用一般现在时还是一般过去时呢?
