蚯蚓通稱地龍，屬環(huán)節(jié)動(dòng)物門，寡毛綱。蚯蚓種類很多，我國(guó)較常見(jiàn)的為巨蚓科環(huán)毛蚓屬。你對(duì)蚯蚓的生活環(huán)境以及生活方式了解多少呢？讓我們一起走進(jìn)下文，來(lái)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(zhì)

4） humus n. 腐殖質(zhì)

我是一條蚯蚓。歡迎來(lái)到我家。我住在一個(gè)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(dāng)一些人走進(jìn)我家時(shí)，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(zhì)。

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

土壤中也含有腐殖質(zhì)。腐殖質(zhì)是一小塊死去的動(dòng)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(zhì)是我的食物。

我家有不同的層次。頂層充滿了腐殖質(zhì)、大量的根、充足的空氣和水。中層有小巖石和一些腐殖質(zhì)。底層由樹(shù)根和基巖組成。我大部分時(shí)候生活在頂層，因?yàn)槟抢镉惺澄铩⒖諝夂退?/p>

我做了很多工作來(lái)修繕我的家。當(dāng)我吃腐殖質(zhì)時(shí)，我會(huì)把它磨成更小的小塊。通過(guò)這種方式，植物也可以用作食物。但我做的不止這些。

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

下次如果你看到我時(shí)，想一想我是如何愛(ài)護(hù)土壤和我的家。
