逐空结合上下文逻辑分析：
1. 第4空：前文提到如果发现风暴来临的预警，不要等下雨，B选项“立刻行动来保障安全”承接内容，提醒人们收到预警马上避险，逻辑通顺。
2. 第5空：前文提到在室内不要靠近门窗，A选项“它们很容易被弄坏”中的They指代前文的门窗，解释了不能靠近门窗的原因，和后文“没有窗户的房间是最安全的”衔接自然。
3. 第6空：前文提到风暴期间不要使用电器、不要玩电脑，可以用看书来代替，E选项“宁愿无聊也不要冒险受伤”承接内容，说明宁愿做无聊的事也不要冒险做危险的事。
4. 第7空：后文提到如果不这么做，响亮的雷声会损伤听力，F选项“另外，待在户外的时候记得捂住耳朵”对应后文避免雷声伤听力的内容，逻辑通顺。
5. 第8空：前文提到闪电很少击中人类，后文转折说明如果真的遇到这种情况要拨打120，C选项“你几乎不会看到这种事发生”衔接前后内容，符合语境。
剩余D、G两个选项不符合文中各处上下文逻辑，予以排除。
