解答

选B
因为all the lights were off不缺成分
而且and前后语序等是一致的前面说：已经检查了门已经锁了后面就应该接着：而且所有灯都关了
这里面不用问问题不用问为什么关、什么时候关、哪里关从结构上分析一下为什么是错的？and前后语序、时态都是一致的....前面叙述后面也是叙述.....................结构上也就这样解释=-=http://zhidao.baidu.com/question/229656384.html 她解释对吗？她解释的不对having checked不能分开解释你说“因为all the lights were off不缺成分”，那that 是引导什么从句？Having checked （that） the doors were closed,and that all the lights were off引导宾语从句
