问题 What will happen if the alarm is switched on?

选项 A、The windows and doors will be opened automatically.
B、Lights will flash throughout the building.
C、The ambulances will be sent to save people’s lives.
D、That emergency power system will switched off.

答案B

解析 题干问的是如果警报打开,会发生什么。根据听力原文可知一旦发生火灾,你要做的第一件事就是通过拉下白色开关启动警报,这样会提醒消防署,随着警报铃声的响起,你将会看到所有楼层的闪光灯被激活,因此警报打开后闪光灯会照亮整个建筑,故选B。
