One morning, sunny, I harbored a happy mood, came to my house in the yard. The flowers in the yard is flourish, a breeze blowing, colorful flowers danced dance, it is refreshing. I think: the watered the flowers, I gingerly to per pot poured the water. After watering in the, I carry the flowers, touch the potted plant, the flowers are like seems very happy to me open a smiley face.
Suddenly, I saw an earthworm, with their feet to block the path of it, thought it would be "detour", can not think of it the "righteous" climbed to my feet. I wonder do earthworms couldn't see a thing? It is how to identify the direction of it?
Me with a problem, catch a worm to do the experiment. I fetched a basin exudes the fragrance of the flowers, bring a colorful toys, each put on left and right sides of the earthworm, and the worms are placed in the middle, see earthworms will move which things. Earthworms in the middle paused for a moment, slowly to the potted flower move in the past. I shall not the solution: do earthworms have no eyes?
So I went on to do an experiment. I put the potted flower replaced the onions. Who knows, the earthworm unexpectedly not hesitate to climb to the onions, which can be really strange. I think: the two experiments, earthworms crawled to the will smell things, earthworm identification method of direction will not smell related? This is just my guess, hasn't been confirmed. So, I went back home, lying on the bed to prove it.
I suddenly looked up and saw there was a thick book, the spine of the written "Encyclopedia" four words in the bookcase. I think: Yeah, I can go to check the Encyclopedia of < >! Really is "where is the friend's home, come without effort".
In the encyclopedia, said: as long as the earthworm in underground activities, eyes gradually degraded, can only rely on the sense of smell to identify the direction.
Someone said a sentence: "the truth was born in the one hundred question mark", through this matter, I have a deep feeling of this sentence. Life is everywhere in the classroom.
