Hey there, little buddy! Let me tell you why we get a cold.
Did you know that there are tiny things inside our bodies called "viruses" and "bacteria"? They're like little troublemakers, and sometimes they can make us sick. When these little troublemakers get into our nose, mouth, or eyes, our body fights with them.
你好啊，小朋友，我们为什么会感冒呢？听我给你解释一下。
你知道吗，我们的身体里有很多小小的东西叫做“病毒”和“细菌”？它们就像是一群小小的坏家伙，有时候会惹我们生病。当这些小坏家伙进到我们的鼻子、嘴巴或眼睛里，我们的身体就会和它们打架。
Our body has a superhero team called the "immune system." They work really hard to fight those little troublemakers, but sometimes the troublemakers can still make us feel unwell. When we have a cold, we might sneeze, have a runny nose, and our throat might hurt.
我们的身体有一个特别厉害的队伍叫做“免疫系统”，就像是个超级英雄队伍。它们会努力打败这些小坏家伙，但有时候小坏家伙还是会弄痛我们。当我们感冒时，我们可能会打喷嚏、流鼻涕，喉咙也会痛。
So, getting a cold happens because our body is having a battle with those troublemakers, and sometimes it can make us feel not so good. But don't worry, we can drink lots of water, rest well, and make our body stronger to fight those little troublemakers!
所以，感冒是因为我们的身体在和坏家伙打架，有时候会让我们不舒服。但别担心，我们可以多喝水、好好休息，让我们的身体变得更强壮，抵抗这些小坏家伙哦！
