When you see lightning, get into a building quickly. When you are indoors, remember not to go near the doors or windows. 5. A room with no windows is the safest place. Don't wash your hands during a storm. Don't risk using anything that runs on electricity(电) either. Even if you really want to play computer games, don't! Try reading a book instead. 6.
If you can't get to a safe building, avoid open areas and stay away from trees. Find a low, dry place and stay low until the storm passes. 7. If you don't, the loud thunder may hurt your hearing.
Lightning does not strike(击中) people very often. 8. But if you do, call 120. Only trained workers know how to care for a person who has been hit by lightning.

逐空结合上下文逻辑分析：
1. 第4空：前文提到察觉到暴风雨来临的自然预警时不要等下雨，衔接B选项“立刻行动来保证安全”，符合行动指引的逻辑。
2. 第5空：前文提醒在室内不要靠近门窗，A选项的They指代门窗，说明门窗在暴风雨中很容易碎裂，和后文“没有窗户的房间是最安全的”衔接自然。
3. 第6空：前文提到暴风雨时不能使用用电设备，只能用看书这类安全的事替代，E选项“宁愿无聊也不要冒险受伤”符合语境。
4. 第7空：后文提到不按要求做的话雷声会损伤听力，对应F选项“另外，待在室外的时候记得捂住你的耳朵”，逻辑完全匹配。
5. 第8空：前文说明闪电很少击中人类，后文转折说如果真遇到这种情况要拨打120，衔接C选项“你几乎不会遇到这种事”，语义通顺。
