Original text: the front of the earth mountain, planted four citron, every year to bear a lot of citron, citron is "orange over Huainan is Hovenia" of Hovenia, but in fact, Hovenia and orange are two kinds of plants. The citron ripens in the fall. The aroma of citron is very strong, not good. But the citron flower smell is very good, bitter-sweet bitter-sweet. The flowers are white, with slightly thick petals, five out of five y lobed, like small wine marigolds, very pretty.

Analysis: this is a description of a plant, mainly its smell, not very good.

Structure: first, the location of the tree, and then write this plant compared to what it is. Focus on the odor of this plant.

imitation: in my old home, there are two kinds of toon trees, one is known as the toon, the one that is often eaten in the spring. The leaves of the tree are just sprouting in spring, so pick the young leaves and use them to scramble eggs or mix them with tofu, which are quite tasty. It can also be eaten as a pickle with salt. I didn't like the flavor when I was young, but I thought it tasted pretty good when I grew up. There is also a kind of called stink toon, its leaves can not be eaten, and there is a very special smell, may be so named, but the wood of this tree is still good.

The imitation of the experience: the original time, some want to write the picture, can only stay in the mind, but now after the imitation, only to find that some descriptions can really be written in a simple way, very simple, but the impression is quite deep.
