六、信息还原。
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有一项为多余选项。
The science of you
You already know that you are an amazing person, but it's not just your wonderful personality. Your body itself is an unusual machine.
Lots of information has been written on the subject of "you". You might wonder about your body. Most people think that the big picture of how your body systems work together is important to understand. Sometimes the details interest us the most. 1
Why don't haircuts hurt? Snip, snip—the scissors fly around your head. Your hair grows from living cells, but the hair that's cut is not alive. What's the story here?
2 The root produces hair cells in a special tube called follicle(毛囊). When new hair cells are made at the root, they push older hair cells up the follicle.
As older hair cells move towards the surface of your skin, they change. They join together and harden. 3 The strand(股) of hair that comes out of your head does not have living cells in it. That's why a haircut doesn't hurt!
You probably have about 100,000 hairs on your head right now. Hair strands grow all the time, then fall out and start to grow again. They usually do this in different stages. 4
5 You might be wide-eyed at one of these things. If you want to know more about them, keep reading.

解析
【分析】
本题为英语信息还原题，需结合上下文语境梳理语篇逻辑，匹配对应选项。先通读全文，明确文章围绕人体（尤其是头发）的有趣细节展开，再逐一分析每个空前后的语境，找到逻辑衔接的选项：
1. 空1前强调“细节最让我们感兴趣”，后文开始讲解理发相关的头发细节，需过渡句衔接；
2. 空2后介绍发根与毛囊的作用，需引出头发生长根源的内容；
3. 空3前讲老头发细胞的变化，后说明理发不疼的原因，需衔接老细胞的最终状态；
4. 空4前讲头发生长、脱落分阶段，需对应分阶段的结果；
5. 空5前讲完头发细节，后提到“这些事情中的一件”，需扩展到身体其他有趣事物的过渡句。
【解析】
1. 空1：前文提到细节最受关注，后文切入头发相关的理发细节，选项C（Let's go on the way to get a haircut.）起到过渡作用，故1选C；
2. 空2：后文介绍发根在毛囊产生细胞，选项E（Each hair on your head grows from a root that is under your skin.）引出头发的生长根源，与后文衔接紧密，故2选E；
3. 空3：前文讲老细胞移动、变硬，后文说明头发无活细胞，选项B（Then they die.）衔接老细胞的变化结果，符合逻辑，故3选B；
4. 空4：前文提到头发生长、脱落分阶段，选项A（That's why you don't lose all of your hair at once.）对应分阶段的结果，即不会一次掉所有头发，故4选A；
5. 空5：前文讲完头发细节，后文提到“这些事情中的一件”，选项F（In fact, your hair is just part of all those interesting things of your body.）将头发细节扩展到身体其他有趣事物，衔接自然，故5选F。
【答案】
