Mother plant has a way of explaining words. 1 "Plant Mother has a way" is a poem about plants spreading seeds. Using metaphor and anthropomorphic rhetoric, this paper vividly introduces the methods of spreading seeds of dandelion, xanthium sibiricum and pea in rhythmic language. From the method of plant mother, we can feel the wonder of nature, stimulate more desire to know about plants, and cultivate the habit of observing things around us carefully.
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, intuitive and full of children's interest, which can not only stimulate students' enthusiasm for learning, but also help them 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".
Mother plant has a way of explaining words. I finished learning the lesson "Mother Plant has an idea" today. In the text, I learned that dandelion spreads its seeds by the wind. Xanthium sibiricum spreads seeds by small animals; Pea is a kind of seed, which spreads after being exposed to the sun when it matures. Mother plant really has a way! But is there another way?
With this question, I went home to check the information with my mother. I also learned a lot of new knowledge, knowing that plants probably have these ways of spreading seeds:
First, the wind mother-in-law helps. Besides dandelion, willow, elm and poplar also spread seeds by wind. White hairs flying all over the sky in spring are the seeds of willow trees.
Second, go with the flow. Coconut trees that grow on the seashore, when the coconuts mature, fall on the seashore and drift to other islands with the seawater, where they take root and grow. Seed propagation is complete. According to statistics, there are more than 100 kinds of plants that spread seeds only by ocean currents in the world!
Third, people sometimes help plants spread seeds. For example, when we eat fruit, we throw away the stone. When the seeds meet the right conditions, they will germinate and grow into fruit trees, such as apples, pears and watermelons.
Fourth, animals will also help. Animals and bird droppings often carry seeds of various plants. With their frequent migration, they will naturally take their seeds to other places, such as grape seeds.
5. Do your own thing. Like peas, when the fruit is ripe, after the fruit is cracked by the sun, the seed generate comes out, and its seeds are sent to all directions, thus completing the spread. Such as soybeans and impatiens.
Plants have no feet, but there are traces of plants all over the world. It seems that they can "travel around the world without their feet". Why? Because "mother plant has an idea"!
Plant mother has a way to explain the text. The third article "Plant mother has a way" is a poem that tells the way dandelion, xanthium sibiricum, pomegranate and pea spread seeds in an anthropomorphic way. This lesson trains students to read sentences and connect them to understand the content of this section. This lesson mainly cultivates students' ability to understand, summarize, read silently, read aloud and collect and use information, and stimulates students' love for nature.
The new curriculum standard points out that "students are the masters of Chinese learning, and Chinese teaching should stimulate students' interest in learning, pay attention to cultivating students' awareness and habits of autonomous learning, create good autonomous learning situations for students, respect students' individual differences, and encourage students to choose their own learning methods". Therefore, in teaching, I first use situational introduction to stimulate interest in learning. Show beautiful pictures of plants with music and ask students to guess the names of these plants. If you don't know them, you can give them interesting names according to their colors and shapes, which will arouse students' interest and love for plants. ) teacher: all kinds of plants are dotted with beautiful nature and dress up our lives. How do plants spread their seeds, grow and reproduce year after year, and let green cover the earth? Let's learn "Mother Plant has a way".
In order to help understand the key points and difficulties of this lesson, I will let students read the content since the enlightenment first, and then deepen their understanding of the text with the help of multimedia. Such as self-reading: this poem introduces several ways in which plants spread seeds. You can also imagine when reading, try to close your eyes and think, smell and listen, and try to feel what you can feel when reading. Then show it in different forms, such as: dandelion spreads seeds through video to let students know that dandelion spreads seeds by wind; The seeds spread by Xanthium sibiricum are displayed by projection; Pomegranate spreads seeds through pictures; Peas spread seeds on the basis of full reading and understanding of sentences, then exchange opinions at the same table, and then use videos to help students understand that peas jump away from their mothers, that is, spread seeds by elasticity.
Finally, it is concluded that there are all kinds of plants in nature, and the methods of spreading seeds by plants are also varied and strange. I hope you can be a careful child and a conscientious person, find more interesting things and phenomena in the embrace of nature and have more fun.
