When I was orphaned express will remind of

When I was orphaned是个状语从句,因此这里的express是个名词.直译是：当我孤独的时候,特快专递将提醒你.（一但我孤独,你就会收到特快专递）显然你并没有收到特快专递的提示.意思就是“我现在真的不孤独.”
从语法上讲,请注意when I 后面用的是was 后面主句用的是will.可以确定I was orphaned是与事实相反,也可以映证 “我并不孤独.”
类似的有：If I were happier than now,I would be twins.(如果我现在能更快乐,我就变成双胞胎了）显然说话的人不是个双胞胎,这句话的意思就是“我此时不可能更快乐了”或“我快乐到极点了”
