阅读理解Nowadays, we have kinds of technologies to protect us from different disasters（灾难）. We even know where and when some disasters, like the typhoon, come. While most of the new technologies are far away from us, some around us can help people in disasters.
The drone（无人机）is one of them. It can be used to send food, water and other important things when a natural disaster happens. Very often the buildings are too dangerous for rescue teams to get in. They can make the drone fly into the buildings to search for those who are still alive first.
Social media is also a useful tool when it comes to natural disasters. With its help, people can know about the natural disasters before they hit. And some social media platforms allow people to mark themselves as safe after disasters so others can know their status.
Social media is also a place for up-to-the-minute news, so people can learn what is going on in the disaster areas. Besides, many social media platforms allow people to donate money to help people in disaster areas. The money will help them get back to their normal life as soon as possible. For example, livestreaming（直播）helped raise a lot of money for Henan after the flood in 2021.
Although these technologies can help when there is a natural disaster, we still need to prepare necessary tools and learn important skills to protect ourselves.
