我们小时候念书的时候，哪个小孩头上长虱子，第一小孩立刻被同学疏远，第二老师有时候会责怪孩子和家长不讲卫生，第三老师有时候也怕其他家长知道而捂着不讲。近日收到女儿学校的一封家长来信，觉得其处理方式十分妥当，十分值得学习。来信如下：
　　Dear Parents,
　　尊敬的各位家长
　　Please be alerted of several incidents of head lice at school.  These cases were reported to us and measures are being made by home and school to remedy and control the situation.
　　　请注意我们学校发现了几件头上长虱子的事情（说是 incidents而不指向学生）。有人向我们汇报了这些情况，学生和家庭都在采取措施控制局面。
　　Parents understandably feel panicked when they hear about head lice.  If you are like most parents, you are likely to ask, “How could this happen?” The fact is that any child, regardless of ethnic, social, or economic status, can get head lice.  Indeed, after the common cold, head lice are more common in childhood than all other issues.  Lice can invade and spread any place children spend time together – in school, day care, or playgroups.  About 10 million children get head lice each year.
　　听说头虱的事情后，家长自然会感到惊慌，这可以理解。您或许会和大部分家长一样问：“怎么会有这种事情？”事实上所有的孩子，不管是什么种族，什么社会阶层，什么经济状况，都有可能生虱子。事实上，生虱子是人童年最多发的问题之一，仅次于感冒。虱子会在孩子们共同相处的很多地方滋生、传播，比如学校，托儿所，儿童游乐场所。每年有1000万孩子的头上会生虱子。
　　If you find lice on your child’s head, examine other family members to see if lice might have spread to them.  To see the lice you might need a strong light and a magnifying glass.  Lice are about the size of a sesame seed and usually gather at the warmest points of the head – at the centerline of the crown, the nape of the neck, and behind the ears.  Lice eggs (also called nits) are tan or white and stick to individual hairs. Lice sometimes cause itching and head scratching, but a sure sign is finding the nits.  Head lice cannot jump or fly; they can only crawl.  Additional information is in the attached flier.  Thank you  for your cooperation in this matter.
　　　如果您在孩子的头上找到了虱子，那么就应该去查看家里其他成员，看有无传播。您必须在明亮的光线下，还要有个放大镜看。虱子一般是芝麻那么大，通常在头部比较暖和的地方，比如头顶发缝，发后稍，耳朵后。 虱子蛋一般是黑色或者白色，通常附着在单独的头发上。虱子会导致头发发痒，孩子们会用手去抓，到底有没有虱子，找一找有无虱子蛋便可分晓。头虱不会跳，也不会飞。它们只能爬。另请察看所附相关信息。感谢您的配合。
　　Sincerely yours,
　　　 此致敬礼
