The umbrella will not only tell you what the weather will be like, but also let you know whether you have left it somewhere. Do you know how it works? The umbrella will be able to send a message to your smart phone. It says, "Hey, it's going to rain in fifteen minutes, so it's best for you to take your umbrella. " Besides, even if you are forgetful, you may never leave the umbrella on a bus or somewhere else again. The umbrella will send a warning(警告) to your smart phone if you are careless and leave it behind.
