An allergy is something which triggers an allergic reaction. This is the immune system defending the body against attack by bacteria and viruses.

Sometimes the systems goes wrong, and is triggered by some quite normal food, or caused when the family pet comes into the room. That is what the ordinary person calls an 'allergy'.

过敏 是 引发 过敏反应的 原因。这是 免疫系统 保护 身体 免受 细菌 和 病毒的 攻击。

有时 免疫系统 会 出错,由 一些 很正常的 食物 触发,或者 家里的 宠物 进入房间时 引起。这就是 一般人 所说的 “过敏症”。
