In two weeks, 46 people walked through Gansu, Qinghai and Inner Mongolia provinces, and crossed the Qinghai-Tibet alpine region, southeast monsoon region and northwest arid region, with a journey of more than 3,000 kilometers. During this period, I learned knowledge through the academic report system, and experienced the rich and colorful landform types in this area through on-the-spot investigation, experienced the unique national culture of Mongolia and Tibet, and enhanced friendship through various forms of networking activities. Now, the joint internship has been successfully concluded. I sorted out my notes and 30-page summary report, and I thought of harvest, joy, professionalism, collision and full gratitude.

In order to prepare for this internship selection exam, I reviewed the relevant knowledge of physical geography. In the next fourteen days, field investigation and measurement proved my book knowledge. At the same time, nature is complex and diverse, and the single knowledge in textbooks has derived many changes and forms of nature. During the internship, the teacher patiently explained the comprehensive geographical knowledge such as geomorphology, pedology, botany, hydrology and meteorology. , led us to investigate the material composition and structural characteristics of the Yellow River terrace and the Hongshui River accumulation terrace, measured the oblique bedding tendency of the ancient sand dunes in Qinwangchuan Basin, and drew the ancient rose map. Excavate, observe and measure the profiles of calcareous soil, gray cinnamon soil of mountain forest and alpine shrub meadow soil; Investigate the remains of ancient glaciers and understand the morphological characteristics of special glacial landforms such as ice bucket, blade ridge and tinder; Crossing Qilian Mountain and Hexi Corridor, the vertical variation law of geology, landform and vegetation types along the way was investigated. Viewing the "bull's-eye model" of salt lake deposition in arid area from the sedimentary profile of Zhuyeze Lake: comparing the similarities and differences between Tengger Desert and Badain Jaran Desert, Benkangdanxia and Zhangye color cracks; Investigate the ancient and modern dikes on the northeast bank of Qinghai Lake; Visit Hong Yashan Reservoir, Haixi Town atomic city, Wuwei Leitai, Confucian Temple and Tang Tian Temple; The experience of tasting white yak yogurt, roast whole sheep, highland barley wine and Wuwei's "three sets of cars" made me deeply understand the significance of Mr. Li Jijun's inscription on the glacier scratch stone "Reading the general principles of poverty in thousands of books and being close to the people in Wan Li", and realized the spiritual inheritance of Huan Zi people's seeking truth from facts, being down-to-earth, being diligent in thinking and studying hard.

In the northwest, we can see both dense vegetation and barren grassland. In the west, which is fragile in ecology and sensitive to climate change, the ecological environment problem is one of the most concerned focuses of human beings. A series of chain reactions, such as land degradation, serious desertification, biological community degradation, abnormal climate, deterioration of hydrological conditions, environmental pollution, destruction of living facilities and construction projects, have sounded the alarm for us. Minqin Oasis in Gansu is shrinking, Populus euphratica forest and Liu Honglin in the lower reaches of Tarim River in Xinjiang are extinct, grassland in Alashan area of Gansu is degraded, Haloxylon ammodendron forest disappears ... A series of grim facts tell us that nature needs to be feared. Learning geography is not to conquer the earth, but to better understand and protect the law.

The cross-integration of multi-disciplines and the "hodgepodge" of geography and history make us curious all the way on the journey, while the wonderful sparks generated by the cultural collision between Hong Kong and the mainland make the originally tired road full of laughter. Baa Baa Da Lei's song, the refreshing tenderness of Mongolian woman Rina, the dialect collision in Hebei, Jiangxi, Northeast China, Nanjing, Shandong, Xinjiang, Henan and Guangdong, the quotations from Duan Ziku, the mixture of Chinese and English in the teacher's explanation, Alice's 20th birthday party ... Fourteen days are very long, on the way of measuring the footsteps, in the corner of endless learning. Fourteen days is very short. How can a teacher with friendship and patience be willing to say goodbye? We all agree that we should go a long way, go to many places, learn more knowledge and appreciate more beauty and grandeur.

Finally, I would like to thank Wang Naiang's witty and knowledgeable teachers, Li Zhuolun, Cai Qiheng, Xu Yong and Wu, who accompanied me day and night as mentors and friends, Master Bao, who is hardworking and funny, and Li Xuejie, who is busy caring about her members, and the opportunity to get 46 of us together during the 20/0/4 summer vacation, leaving unforgettable memories.

Go to three provinces, cross thousands of miles, and spend more than ten days on rivers and mountains;

Climb the snow-capped mountains, cross the grassland and measure four kilometers;

Digging profiles, looking at bedding, and exploring underground for hundreds of millions of years;

Look at Danxia, look at the bad land, there are differences between true and false, and similarities are different;

Advance and retreat of river terraces, lakeshore and side lake;

Going to Kyushu from heaven to earth is both natural and humanistic;

Crossing Qilian, desert and Silk Road, visiting ancient and modern times;

The friendship between the two sides of the strait, live together day and night, hand in hand through the two plateaus.

Time flies, the past is like a song, thank you for accompanying me all the way!
