My plants

"Do you find that your plants are dying?" Mr. Li asked when he finished his class.
"What?" I shouted, I just bought the plants, two kinds of bamboo, from the flower market last week. I looked the plants carefully, I found that they are not healthy, one bottle with plants has some worms swimming in the water, and another plant has a black on the root, it seems has decomposed .

After thanked Mr. Li, I became to clipped the bamboo. I changed the water of the bottle and cut the broken root. Quickly, the water became clean and the bamboo looks more beautiful and greener.
