12．Just at that moment I had a “time lag” flashback and saw the area again as it had been in the year AD 2008.就在那一时刻，我得了时间滞后症，在我脑海里，这个地方又闪回到公元2008年。

1) time lag指乘坐时间太空舱穿梭未来时由于速度极快而产生的“时间滞后症”，与jet lag喷气式飞行时差综合症，即乘飞机跨越时区时人体的生物钟或昼夜生理节律仍然停留在原时区的状态类似。

2) as it had been in the year AD 2005 是方式状语从句,修饰主句I saw the area again ;

as it had been 是由as it be变来的， as it be表示 “按照原状, 照旧, 像 ”

The situation is as it was before.形势还是原来那样.

13. Then Wang Ping flashed a switch on a computer screen, and a table and chairs rose from under the floor as if by magic. 王平闪了一下电脑屏幕上的开关，于是一张桌子和几把椅子就像魔术般地从地面升了起来。

1） 本句有两个句子并列，前两者之间用逗号隔开最后两者之间用and连接；

2) 后面的一个分句使用了倒装句，主要是为避免头重脚轻，使句子平衡，同时也可使前后联系得更加紧密，正常语序是a switch on a computer screen flashed；

3) 此处as if 引导的是一个省略的方式状语从句，其完整句子是as if a table and chairs rose from under the floor by magic

4）switch 用作名词表示“开关；转换”。用作动词表示“转换，改变”。

She made the switch from full-time to part-time work when her first child was born.。

第一个孩子出生后，她就由全日工作改为非全日工作。
