C
After the haircut
It’s getting hot. You go to have your hair cut. The barber Tony cuts off part of your hair and sweeps it away, but your hair’s journey is not over after the haircut.
Have you ever thought of planting your old hair after it’s cut off? Some farmers do!
What comes up? Not wigs(假发), but bigger and tastier crops. Hair is full of nitrogen(氮) that helps plants to grow. When the cut hair is mixed into soil, the hair breaks down, slowly letting out nitrogen. Then it can help flowers and vegetables get big a little faster.
If you’ve got a wool sweater on, you’re wearing a sheep’s haircut. Sheep grow fine curly(卷曲的) fur called wool. All those curls make air pockets that trap heat, keeping the sheep warm. Farmers shear the sheep in summer, so the sheep don’t feel too hot. And we use the wool to make warm clothes, socks, and hats. Wool can even take in rain while remaining dry.
Wool doesn’t catch fire easily, either.
What does your hair say about you? Even many years after it has been cut off, hair still can tell surprising secrets because hair is composed of bits of old cells. It has traces(微量) of chemicals(化学物质) that were in body when the hair grew. When people are kept in the situation of dangerous chemicals, these traces remain in the hair, even long after they have disappeared from the body itself. Testing hair can help doctors know if there are dangerous chemicals in food and water. Hair can tell another important secret—whose hair is it? This can be used to help solve crimes.
Hair does so many things for us. It keeps us warm, helps farmers, shows mysteries, and provides endless styling fun. One thing is for sure—it’s not just for wigs any more.

### C
#### 理发之后
天气越来越热了。你去理发。理发师托尼剪掉你一部分头发并把它扫走，但理发之后，你的头发的旅程还没有结束。
你有没有想过在旧头发被剪掉之后种植它？一些农民会这么做！
会长出什么呢？不是假发，而是更大、更美味的庄稼。头发富含氮，氮有助于植物生长。当剪下的头发混入土壤中时，头发会分解，缓慢地释放出氮。然后它可以帮助花卉和蔬菜长得更快一点。
如果你穿着一件羊毛毛衣，你就穿着羊的“头发”。羊会长出叫做羊毛的细卷毛。所有这些卷曲的毛会形成气穴，留住热量，让羊保持温暖。农民在夏天给羊剪毛，这样羊就不会觉得太热。我们用羊毛制作保暖的衣服、袜子和帽子。羊毛甚至能吸收雨水同时保持干燥。
羊毛也不容易着火。
你的头发能透露关于你的什么信息呢？即使在头发被剪掉很多年后，它仍然能透露令人惊讶的秘密，因为头发是由旧细胞碎片组成的。它含有头发生长时体内存在的微量化学物质。当人们处于危险化学物质的环境中时，这些微量物质会留在头发中，即使在它们从身体本身消失很久之后也是如此。检测头发可以帮助医生了解食物和水中是否有危险化学物质。头发还能透露另一个重要秘密——这是谁的头发？这可以用来帮助破案。
头发为我们做了很多事情。它让我们保暖，帮助农民，揭示奥秘，还能带来无尽的造型乐趣。有一点是肯定的——它不再仅仅用来做假发了。
8. 我们可能在杂志的哪个部分读到这篇文章？
A. 自然。
B. 科学。
C. 历史。
D. 健康。
9. 划线部分“shear the sheep”是什么意思？
A. 给羊足够的食物。
B. 多次清洗羊。
C. 为羊找一个居住的地方。
D. 剪掉羊身上的羊毛。
10. 第四段的主要意思是什么？
A. 头发有助于保暖。
B. 头发检测很重要。
C. 头发能透露秘密。
D. 头发有助于破案。
