How to rewrite The Return of the Wild Goose with explanatory words

Just delete those narratives and descriptive sentences: the geese return (explanatory text) When a flock of geese broke through the fog of the March warm current, spring came. Birds flying south in October (165438+) fly high above our heads, and even when they find their favorite beaches and swamps, they are almost silent. Crows are usually considered to fly in a straight line, but compared with geese flying 200 miles south to the nearest Great Lakes, their flight is curved. When the geese arrive at their destination, they sometimes wander on the wide water and sometimes run to the newly harvested corn fields to pick up corn kernels. Once the first group of geese came here, they clamored to invite every group of migrating geese. Within a few days, they were everywhere in the swamp. In April 1946, 1 1, we recorded 642 geese. By observing the gathering routine of spring geese, people noticed that all lonely geese have a * * * nature: they frequently fly and sing, and their voices are melancholy, so people came to the conclusion that these lonely geese are sad and single. My students and I noticed the number of each goose team. Six years later, in the interpretation of The Lonely Goose, a lot of unexpected things happened. From the numerical analysis, it is found that occasionally there are more geese than 1 composed of 6 or multiples of 6. In other words, the geese are some families, or the aggregation of some families. Those lonely geese are only roughly in line with our previous imagination. They are survivors who have lost their loved ones. Dull numbers can arouse the sadness of bird lovers. On April nights, when the weather is warm enough to stay outdoors, people only hear the sound of snipes flapping their wings, the cry of distant owls, or the gurgling sound from the nose of affectionate American sandpipers. Then, suddenly, the harsh goose cry appeared, accompanied by a rapid and chaotic echo. There is the sound of wings flapping on the water, and the sound of fins flapping. From Pleistocene [early Quaternary, from 6.5438+06 million years ago to 6.5438+00 million years ago. Since March, geese have migrated from China Sea to Siberia, from Euphrates River to Volga River, from Nile River to Murmansk, and from Lincolnshire to Spitsbergen Islands.
