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。选项中有两项为多余选项。
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.
A. That's why you don't lose all of your hair at once.
B. Then they die.
C. Let's go on the way to get a haircut.
D. You have too many hairs growing
your head.
E. Each hair on your head grows from a root that is under your skin.
F. In fact, your hair is just part of all those interesting things of your body.
G. So, don't cut your hair too often.

【分析】
这是一道英语信息还原题，需结合上下文的逻辑关系、话题衔接来选择合适的句子。解题时先通读全文，把握文章主题是介绍身体（尤其是头发）的有趣细节；再逐一分析每个空的前后语境，匹配对应选项：
1. 空1前句提到“细节最让我们感兴趣”，后句开始讲理发相关的头发知识，需引出理发话题，对应选项C；
2. 空2后句围绕“root（发根）”展开说明，需先引出发根的来源，对应选项E；
3. 空3前句说旧头发细胞移动、硬化，后句指出头发无活细胞，中间需衔接细胞死亡的逻辑，对应选项B；
4. 空4前句提到头发生长脱落分不同阶段，需说明不会一次掉光的结果，对应选项A；
5. 空5后句说“对这些事情感到惊讶”，需总结头发是身体有趣部分，对应选项F。
【解析】
1. 空1：前文强调细节的吸引力，后文切入理发相关的头发知识，选项C“Let's go on the way to get a haircut.”起到过渡到理发话题的作用，符合逻辑，故选C；
2. 空2：后文围绕“root（发根）”展开说明，选项E“Each hair on your head grows from a root that is under your skin.”引出发根的来源，衔接下文，故选E；
3. 空3：前文提到旧头发细胞移动、硬化，后文指出头发无活细胞，选项B“Then they die.”说明细胞硬化后的结果（死亡），逻辑连贯，故选B；
4. 空4：前文说明头发生长、脱落分不同阶段，选项A“That's why you don't lose all of your hair at once.”解释了分阶段的结果（不会一次掉光），因果对应，故选A；
5. 空5：后文提到“对这些事情感到惊讶”，选项F“In fact, your hair is just part of all those interesting things of your body.”总结头发是身体有趣部分，引出下文的惊讶点，故选F。
