Zhejiang Tide is qiantang bore.
Qiantang river tidal bore
Qiantang bore-the most spectacular tide.
In the history of our country, there are three famous tidal bore: Qingzhou tidal bore, Guanglingtao tidal bore and qiantang bore tidal bore.
Causes of tidal bore in Qianjiang River
The spectacular Qian Jiangchao is not only influenced by the gravity of the moon and the sun, but also related to the trumpet-shaped mouth of Qiantang River. Nearly 500,000 mu of reclaimed land east of Zheshan in Jiang Nanan, Qiantang blocked the estuary like a peninsula, making the section from Zheshan to Qiantang River 12 like a small belly bottle, and the tide is easy to enter but difficult to retreat. The outer mouth of Hangzhou Bay is 100 km wide, and it is only a few kilometers wide outside 12. The riverbed in the eastern part of the estuary suddenly rises and the beach is shallow. When a large number of tides flood in from the mouth of Qiantang River, the river surface shrinks rapidly, and secondly, it is related to excessive sediment deposition under Qiantang River, which blocks and rubs the tidal current and makes the front slope of the tidal current steep and gentle, thus forming a wave after catching up with the front wave, wave after wave, wave after wave. There are many beautiful scenery in the world, such as sunrise and sunset, spring goes and spring comes, clouds fall and snow falls, mountains, seas, lakes, places of interest, towns and villages, streets and courtyards ... which one is not worth eulogizing in poetic language, but writing landscape composition is a headache for primary school students. Why? One is that there are no good words and sentences in the chest, and the other is that the composition is in the wrong order.
The first unit of the ninth volume of six-year primary school Chinese published by People's Education Press focuses on the composition of training, which is to write the composition of scenery. According to the present situation of primary school students' landscape composition and the arrangement of textbooks, how should I train landscape composition?
First, close contact with the text to guide writing
Sunrise and sunset at sea, the charming Zhangjiajie in Unit 1 and the Three Pagodas in Dali are all good examples of writing about scenery.
Sunrise at sea writes down the process of sunrise in the order of things. "Afterglow" wrote a poetic afterglow in chronological order; The Three Pagodas in Dali describes the appearance of the three pagodas according to spatial order. Students should write landscape writing in a certain order and have seen various orders. Students also know that to write a landscape composition, we should "express our feelings in the landscape", describe it with emotion, expand our imagination, and try our best to use vivid language and appropriate techniques. Such as association, metaphor, exaggeration, etc. Only in this way can the boring scenery description become full of vitality and interest and attract readers. Of course, students also know that the article is so detailed and vivid, thanks to the careful observation of the author.
Second, read thousands of books and read sentences.
"A clever woman can't cook without rice." Only by studying thousands of books can we walk on the road of Wan Li. In order to write a good composition about scenery, it is imperative to accumulate a certain amount of vocabulary about scenery. It took two weeks to strengthen the training of words. Students like articles about landscapes and accumulate good words and sentences by reading aloud, reciting and abstracting.
Third, observe carefully and grasp the characteristics.
After the above two links, the students are ready to write a landscape composition. The following are practical exercises. As it happens, God helps me! It rained heavily that day and it was dark. Heavy rain poured in. I seized this opportunity to let the students observe this sudden rainstorm, and the students observed it very carefully. After that, the students wrote down the rainstorm in the order of things and wrote down its characteristics. One of the students wrote that when it was raining cats and dogs, thick raindrops fell violently on the roof, and the whole sky seemed to collapse. Lightning, thunder and storms seem to engulf the whole world. It's raining harder, and a huge bead curtain hangs on the ground. Another student wrote that it was sunny and rainy, and the heavy rain finally cleared up, and the rain gradually subsided. The trees stood up again in high spirits, the dark clouds gradually receded, and the sun smiled.
After this exercise, I asked the students to observe the campus and write down the campus scenery. When writing about the campus in autumn, the student captured the "ugly chrysanthemum" with keen eyes, and wrote with his unique perspective that the white flowers withered, but the ugly chrysanthemum shone alone. He wrote in his composition: colorful flowers in autumn don't want to fade first, but want to go on. At this time, the ugly chrysanthemum opened, and other flowers bowed their heads willingly when they saw the beautiful flowers of the ugly chrysanthemum.
Through the interlocking of these three links, students have written a satisfactory composition. Of course, this is not the end of the play, it is a matter of persistence. I believe that students will open their eyes to see the world, pay attention to observation, pay attention to life and keep wonderful in their future lives! Find it yourself.
