六、任务型阅读。
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.
