Zhu Kezhen (1890- 1974) was born in Shaoxing, Zhejiang. /kloc-entered Tangshan mine road school at the age of 0/6, and was admitted to the United States to study in 19 10.
After that, he studied meteorology in the geography department of Harvard University. After graduation, I returned to my motherland to serve and became an outstanding scientist.
This is an article telling a true story. The author interspersed appropriate arguments in the narrative to touch the lofty ideological realm of the characters; safe
Arrange a number of scenery descriptions, publicize the environmental atmosphere and the inner activities of the characters: this enriches the characters' images in many ways and increases the articles.
The glory of.
Pay attention to understand the meaning of the following words and read the correct pronunciation.

In spring, in Beihai Park, there is often an old man with a thin face and hale spirits who goes to work in the morning.
The north gate enters the garden, and the south gate exits. In the afternoon, after work, the south gate enters the garden and the north gate exits. The old man is outstanding.
Scientist Zhu Kezhen. From his residence to his office, he passed Beihai Park. He could have taken the bus.
Go by car, but he would rather walk through the park. He came and went in this way and spent many beautiful springs.
Did Zhu Kezhen go to Beihai Park to enjoy the scenery? No. He is here to observe phenology and do science.
Research. The purpose of his study of phenology is to master the changing laws of natural phenomena and understand the influence of climate change.
The influence of biology serves the socialist agricultural production.
He came to the shore of the North Sea and observed carefully: when the peach blossoms bloom, when Liu comes, and when the cuckoo is there.
I did it. He recorded the changes of these natural phenomena in detail. When you feel nervous at work or when you go out,
Let the wife help keep an eye on when the swallows fly, and let the daughter help observe when the ice in the North Sea freezes.
Hou Churong also asked his neighbor's children to report to him on the day when the first apricot blossom opened.
Every morning, when he gets together, he takes the pen thermometer in a copper sleeve to the yard.
Do morning exercises in the room. After doing morning exercises, I took the thermometer into the house and recorded the measured temperature. this
Thermometer, he often puts it in the small pocket on the left side of his coat. Sticked for a long time, covered with a small pocket.
It always wears out first. In this way, when making clothes, his wife asked the garment worker to make a small pocket cover.
Keep the cloth and change it.
After years of observation, he accumulated rich phenological records and drew a map of phenological changes in Beijing in spring.
Charts. This picture shows the spring phenological changes of 1950- 1972 in Beijing in the past 23 years.
The preface provides a scientific basis for compiling the natural calendar. In his works, we can see this kind of intentional picture.
A chart of meaning.
In order to make scientific research serve production better, Zhu Kezhen is not limited to observing in Beihai. He is 70 years old.
When I was a teenager, I put on wear-resistant tennis shoes and went to work in the field. Always go with that pen-like temperature.
Scale with compass, altimeter and camera. This is his Four Treasures of the Study. Wherever I go, I always go first.
Take out the compass to set the direction, then measure the height with an altimeter, the temperature with a thermometer, and then use a camera.
Some landscapes were photographed as materials for scientific research.
After in-depth investigation and practice, he wrote Some Features of Climate and Grain Production in China.
The relationship between material production, comprehensively analyzes the effects of light, temperature and precipitation on crop growth.
It is considered that China's agricultural production still has great potential, and some ways to give play to these potentials are pointed out.
It opens up new prospects for climate work and agricultural production.
"1February 6, 964, the temperature was 1℃-4.4℃, the air pressure was 764 mm, and there was half an inch of snow on the ground." India
Ke Zhen wrote a diary with a red pen. This afternoon 1: 30, I was invited to Chairman Mao's residence in Zhongnanhai.
Location. Chu Qing after the snow, lush trees, picturesque. He walked into Chairman Mao's bedroom, and Chairman Mao smiled.
Face him and shake his hand. He sat down in the chair in front of Chairman Mao's bed and was about to say hello when Chairman Mao spoke first.
Chairman Mao said that after reading his book "On the Relationship between Some Characteristics of China Climate and Food Crop Production", it was really.
Think of the agricultural eight-character constitution governing the land regardless of the sky; In addition to "soil, fertilizer, water, planting, density, safety, management and work"
In addition, the words "light" and "qi" can be added.
Chairman Mao talked with great interest about how sunlight can synthesize carbohydrates from water and carbon dioxide.
It's a pity that we tried hard and didn't make full use of it. Zhu Kezhen reported his research to Chairman Mao.
The process and results of the investigation. After a while, two scientists, Li Siguang and Qian Xuesen, were also invited to visit. house
The atmosphere is more active. Chairman Mao and three scientists talked extensively about the formation of the earth and biological evolution.
Climate change in qualitative era and historical era, macro-world and micro-world, dialectics of positive and negative electrons.
Law and so on. The three scientists listened attentively to Chairman Mao's words and got new enlightenment. Laughing and laughing during the dinner.
Life is already dusk. When he left, Chairman Mao said to everyone, What other works are there? Give them to him.
Look at that. The next day, Zhu Kezhen wrote a letter full of "the world climate fluctuation in the historical era"
And phenology to Chairman Mao.
The "kingdom of freedom" has no end, and the exploration of scientists will not stop. Zhu Kezhen, who is in his 70 s, is still
However, he tirelessly carried out scientific research. He learned from a large number of historical books, local chronicles and the days of the ancients in ancient China.
Looking for clues about ancient climate in notes, travel notes and poems, I wrote "Climate Change in China in the Past Five Thousand Years"
Preliminary study. This book is highly praised by academic circles at home and abroad. Its value lies in fully grasping history.
Making the past serve the present is very beneficial to long-term climate prediction. Zhu Kezhen is 83 years old.
Age, make new achievements in science and win new honors for the motherland.
1973 On May 27th, the swallow returned and the cuckoo reported for duty. The highest temperature of the day has been reached.
27 degrees. At 5 pm, Premier Zhou of the State Council met with Zhu Kezhen, head of the delegation of American scientists, in the West Hall of the Great Hall of the People.
Also participated. Premier Zhou kindly told him: "A preliminary study of climate change in China in the last five thousand years" was written by you.
Research, I saw it. You can also make some popular explanations for world climate change. "When parting, goodbye.
He said to him, "There is still14 time in 2 1 century, 19. When Guo is 100 years old, you will be 17 years old.
Zhang wrote a book until he was 92 years old. You can also write many books. "
Deeply moved, Zhu Kezhen greeted Premier Zhou with a smile. He thought, I also wrote 92 years old! However, he
My health is getting worse and worse. He is still concerned about climate change. He wrote in his diary of 65438+February 3 1 this year.
Tao: "The climate circles in the Soviet Union are publicizing the news that the earth is getting cold again, saying that Leningrad has been below 1940 in recent years.
1℃ I have pointed out in the Preliminary Study on Climate Change in China in the Last Five Thousand Years that this temperature is around 1℃.
The changes in the past 5000 years are extremely common, which is not evidence that the earth is getting cold. "He also used a red pen here.
At the beginning of the paragraph, write down the word "worried about the sky" as the title. This can be said to be his last work.
1February 6, 974 was the day before Zhu Kezhen died. When he was dying, he did not forget to do scientific research.
Record, with trembling handwriting, write down the weather on the bed: "The highest temperature is below zero.
1℃, minimum minus 7℃, easterly wind 1-2, sunny to cloudy. "At that time, he can't see it in person outside.
The temperature measurement was recorded according to the report of the Meteorological Bureau, so the words "local report" were also marked. This Zhuo
The Vietnamese scientist didn't break up with his beloved scientific research until the end of his glorious life. Taliu
Under the scientific heritage that people need. His research results will struggle in today's and future production.
And emits light for a long time in scientific experiments.
