有一次科学程老师带领我们去挖土。接着老师给了我们每人一个铲子，老师一声令下，我们蜂拥而至的跑到教学楼后面。我用手捏一捏，湿湿的，又拿了一点闻闻，好臭为什们呢？有的小朋友说：“有的`人在这里大小便”。我不知道便问老师，老师说：“是因为树上的叶子落在土地上，腐烂了，才会臭”。“哦原来如此”突然我们班上的一名同学大叫起来：“啊！是条蚯蚓”。大家纷纷跑来，：“呀是条蚯蚓”。在大家的帮助下，我们将蚯蚓埋了起来。
Once science teacher Cheng led us to dig earth. Then the teacher gave each of us a shovel. At the teacher"s command, we rushed to the back of the teaching building. I pinch it with my hand. It"s wet and I smell it. Why is it so smelly? Some children said, "some people urinate here.". I do not know to ask the teacher, the teacher said: "because the leaves fall on the ground, rotten, will stink.". "Oh, I see." suddenly one of our classmates shouted, "ah! It"s an earthworm. Everyone came and said, "ah, it"s an earthworm.". With your help, we buried the earthworm.
