Before teaching, teachers can ask students to collect large numbers in real life through different channels, or make full use of the information provided by textbooks to guide students to discuss with the help of existing knowledge and experience, to understand the size of100000 and100000, and to feel the significance of large numbers. Students can collect a lot of relevant data and learn more information while learning reading materials. Reading and writing numbers is the focus of this unit.
The main content of "tide watching"
This is a reading text. Through what I have seen and heard, this paper introduces the magnificent and peculiar natural landscape of Qiantang River, which is called "the wonder of the world".
The central idea of tide watching
This paper introduces the tide of Qiantang River, which has been called "the wonder of the world" since ancient times, and expresses the author's thoughts and feelings of loving nature and the great rivers and mountains of the motherland.
The content of Watching the Tide and the characteristics of its language description;
Although this article only has more than 200 words, it describes the majestic scene of the Qiantang River tide, the moving scene of the water army exercise, the superb tidal-making skills of Wuzhong athletes and the grand occasion of watching the tide. The beauty of nature and the beauty of humanity are intertwined, giving people an immersive feeling and edifying people with beauty.
The language of this paper is very distinctive, which can be realized by taking the description of the magnificent scene of Qiantang River tide as an example. In this paper, the spectacular tides of Qiantang River from far to near are depicted by figurative metaphor and artistic exaggeration. The beauty of menarche "like a silver line", the strange sight of "Yucheng Snow Ridge" when the tide approached, and the loud noise of "thunder and explosion" left an indelible impression on people. Lenovo also led to Yang Wanli's famous sentence "Silver in the sea is the country, jade in the river is the waist", which added poetic meaning to Qiantang Kong.
