《虱子真讨厌》，作者：谢丽尔·赖夫-斯奈德。 核心问题：关于头虱，我们需要知道哪些重要知识？

Who gets head lice? Head lice love to chomp on human heads. They have bugged people for thousands of years. Yet many people don't understand what they are or where they come from. Some people think head lice are a sign of a filthy home. Others think only people who don't wash enough get them.

谁会得头虱？ 头虱最爱在人的脑袋上觅食， 它们已经烦扰人类好几千年了。 但很多人还是不清楚它们是什么、从哪里来。 有些人觉得长头虱就代表家里很脏， 还有些人觉得只有不爱干净的人才会长头虱。

From Louse to Lice When you see more than one mouse you don't call them mouses, right? You call them mice. In the same way, One of these insects is called a louse But two or more are called lice. in fact Who gets lice has nothing to do with how clean your home or school is It's not about how often you wash or brush your hair It's not about your hair length either. Head lice affect people who are rich and people who are poor. They affect people all over the world

从“louse”到“lice”， 你看到不止一只老鼠的时候，不会把它们叫“mouses”对吧？ 你会叫它们“mice”。 同样的道理，一只这种小虫叫做“louse” 两只或更多就叫做“lice”， 其实呀，会不会长虱子，和你家或者学校干不干净一点关系都没有 和你洗头梳头勤不勤也没关系 和你的头发长短也不搭边， 不管是有钱人还是穷人，都可能会长头虱。 全世界的人都可能被头虱找上门

Name that louse. Different types of lice live on humans. They all feed on human blood. Body lice and head lice look almost the same, but head lice are a bit smaller. An adult head louse is about the size of a pencil point.

认识虱子的种类 寄生在人身上的虱子有好几种 它们都靠吸食人血生存 体虱和头虱长得几乎一模一样 不过头虱的个头要小一点 一只成年头虱差不多和铅笔尖一样大

Their small size makes them tough to spot and tough to catch. Strong claws on their legs help them hold tight to human hair.

它们个头太小了，所以很难发现，也很难捉到 腿上结实的小爪子能帮它们牢牢抓在人的头发上

How do we get head lice? Head lice usually spread when people touch heads. Sometimes, they spread when a person with head lice shares a hat, comb, or other item. The louse can hitch a ride on the shared item to reach a new person.

我们是怎么长头虱的呢？ 头虱通常在人们头挨头接触的时候传播 有时候，长头虱的人共用帽子、梳子或者其他物品也会传播头虱 虱子会搭这些共用物品的“顺风车”，跑到新的人身上去
