An Earthworm’s Home 蚯蚓的家

顧光才

蚯蚓通稱地龍，屬環節動物門，寡毛綱。蚯蚓種類很多，我國較常見的為巨蚓科環毛蚓屬。你對蚯蚓的生活環境以及生活方式了解多少呢？讓我們一起走進下文，來看看一條蚯蚓的自述吧！

Im an earthworm. Welcome to my home. I live in a wonderful place withplenty of food， fresh air， and just the right amount of moisture.

When some people come into my home， all they see is dirt. Soil is alot more than dirt. It includes 1）ground and partly 2）dissolved rocks and3）minerals.

Soil contains water and air， too. They are good things for me. I needwater to keep my skin moist. I get air from the soil. Can you believe it？ Ibreathe through my skin！

Soil also has 4）humus in it. Humus is small bits of dead plants andanimals. Humus is usually brown or black， so it can change the color of thesoil. Humus is food for me.

My home has different layers. The top layer is full of humus， lots of roots，and plenty of air and water. The middle layer has small rocks and somehumus. The bottom layer is made up of tree roots and bedrock. I mostly livein the top layers where there is food， air， and water.

I do a lot to fix up my home. When I eat humus， I grind it into even?smaller bits. In this way， plants can use it as food. But I do more than that.

When I crawl through the soil， I mix the layers. My tunnels help bring air，water， and food to other living things. Even the slime on my skin is good forthe soil.

Next time if you see an earthworm like me， think about how I care for thesoil， my home.

1） ground adj. 磨碎的

2） dissolve v. （使）溶解

3） mineral n. 礦物質

4） humus n. 腐殖質

我是一條蚯蚓。歡迎來到我家。我住在一個很好的地方，那里有充足的食物、新鮮的空氣和恰到好處的水分。

當一些人走進我家時，他們看到的都是泥土。土壤不僅僅是泥土，還包括磨碎的巖石和部分溶解的礦物質。

土壤也含有水和空氣，它們對我很好。我需要水來保持皮膚濕潤。我從土壤中獲得空氣。你能相信嗎？我通過皮膚呼吸！

土壤中也含有腐殖質。腐殖質是一小塊死去的動植物，通常呈棕色或黑色，因此它可以改變土壤的顏色。腐殖質是我的食物。

我家有不同的層次。頂層充滿了腐殖質、大量的根、充足的空氣和水。中層有小巖石和一些腐殖質。底層由樹根和基巖組成。我大部分時候生活在頂層，因為那里有食物、空氣和水。

我做了很多工作來修繕我的家。當我吃腐殖質時，我會把它磨成更小的小塊。通過這種方式，植物也可以用作食物。但我做的不止這些。

當我在土壤中爬行時，我會把不同的層次混合起來。我的洞穴通道有助于為其他生物帶來空氣、水和食物，甚至我皮膚上的黏液對土壤也有好處。

下次如果你看到我時，想一想我是如何愛護土壤和我的家。
