The whole poem consists of five sections, which are developed according to the idea of "asking questions-specific introduction-prompting observation". The first section stimulates students to think: what methods do plants use to spread seeds; The second, third and fourth sections describe the methods of spreading seeds by Taraxacum mongolicum, Xanthium sibiricum and Pistacia tonkinensis respectively. The fifth part encourages students to observe carefully and discover new knowledge. Text illustrations, combined with beautiful poems, vividly describe three ways in which plants spread seeds. Pictures are vivid and intuitive, full of children's interest, which can not only stimulate students' enthusiasm for learning, but also help students understand things and keywords.
The outstanding feature of this paper is that it uses anthropomorphic methods to write plants and seeds as "mother" and "child" respectively. The connection of "mother and child" is easy to touch the emotional world of children, stimulate imagination and lead to thinking. In the first section, the word "travel" means that the seeds leave the plant mother and fall to other places, and the word "cosmopolitan" means that the plant seeds take root and sprout in various places. The second to fourth sections specifically introduce the self-conditions, external conditions and modes of spreading seeds of three plants. Among them, "parachute", "thorn nail" and "pod" are the conditions of plants themselves; "Wind", "animal hair" and "sun" are external conditions; "Riding", "hanging" and "exploding" are three ways of plant seed transmission. In this paper, dandelion and xanthium sibiricum are compared to "parachute" and "barbed armor" respectively, and their shapes are accurately and vividly outlined. Use the words "prepare", "give" and "put on" to give the vegetative feelings and write the spirituality of plants; The onomatopoeic word "pa" accurately describes the sound of pod bursting. In addition, poetry emphasizes the rhyme "A" and is catchy to read.
Another feature of this poem's language is its flexibility and diversity. For example, it is also said that the seeds leave the plant mother, and different expressions are adopted in the poem: "Children will start in the wind", "Children will go to fields and valleys" and "Children will skip from their mothers". In the fifth section, there are many ways for plants to spread seeds, but only three of them are introduced in this paper. There are countless plants in nature, and it is difficult to give examples of ways to spread seeds. Therefore, the author uses the overlapping words "many, many" to summarize them, skillfully uses "unbelief" to arouse readers' impulse to find out, and uses "careless children can't get it" to express the meaning that "children who observe carefully will get it".
