Jinan is a favorite place of nature, which embodies the beauty of Jinan in winter and the author's love for it. The meaning of the first sentence provides you with an understanding for your reference: one view is that the ontology is "red roof, yellow grass mountain" and the metaphor is "small gray shadow of flowers on the carpet". There are several aspects that are difficult to explain for this view: First, the understanding of vehicles. The central word of this sentence should be "small gray tree shadow", and "small flowers on the carpet" and "small flowers" are attributes. In other words: "Red roof, Huangcaoshan is like a small gray shadow"; In this way, the second question comes out. According to the definition of metaphor, metaphor is analogy. When describing something or explaining a truth, use other similar things or truths as examples. It is emphasized that there should be "similarities" between ontology and vehicles, so what are the similarities between "roof", "grass mountain" and "tree shadow"? Besides, there is a third aspect, that is, what is the explanation for the change of color? The roof is red, the grass hills are yellow, and the shadows of trees are gray. Do red and yellow change color in blue? Even if there is, will red and yellow turn gray at the same time? The second view is that the ontology is a' small gray shadow' and the metaphor is a' small flower on the carpet'. From this point of view, the metaphor is limited to the second half of the sentence, not the whole sentence, that is, "little ash tree image of flowers on the carpet", then the whole sentence means: "This crystal is covered with red roofs, Huangcaoshan, little ash tree image of flowers on the carpet." The essence of this sentence is: "crystal covers the roof, and the grass hills and trees shadow." Although this sentence is very consistent with the content of the article, it is not obviously a figurative sentence from the main part of the sentence. Moreover, the word order of this sentence is also difficult to explain. So this view is also difficult to convince the public. Later, I went to Jishou University to study and discuss this sentence with my classmates. Everyone has the same opinion. A classmate suggested that this sentence is a metaphor. Metaphor compares one thing to many things. This statement is obviously wrong. Finally, in the absence of a unified opinion, I consulted Professor Tang of Jishou University, and he gave me the answer: "The crystal is covered with red tops, and the yellow grass mountain" is the ontology, which is a metaphor for "the small gray shadow spent on the carpet". The metaphor process is: the crystal is like a carpet, and the red roof is like a small flower on the carpet; Huangcaoshan is like a small gray shadow on the carpet. For this statement, I once questioned the color change of "yellow" and "gray", but on second thought, the dead skin is still covered with a layer of Bo Xue, and it is also appropriate to use "gray" color.
