Life in the future未来的⽣生活Dear Mum and Dad, I still cannot believe that I am taking up this prize that I won last year. I have to remind myself constantly that I am really in AD 3008. Worried about the journey, I was unsettled for the first few days. As a result, I suffered from “Time lag”. This is similar to the “jet lag” you get from flying, but it seems you keep getting flashbacks from your previous time period. So I was very nervous and uncertain at first. However, my friend and guide, Wang Ping, was very understanding and gave me some green tablets which helped a lot. Well-known for their expertise, his parents' company, called "Future T ours", transported me safely into the future in a time capsule.亲爱的爸爸妈妈，我仍然不不敢相信我正在接受我去年年赢得的这个奖。
我不不得不不时时提醒⾃自⼰己，我真的在公元3008年年。
我很担⼼心这次旅⾏行行，在最开始的⼏几天很不不安。
