What are the key words in the composition about my silly second uncle?

My second uncle

My second uncle is over 40 years old. He is an honest farmer. Although he is uneducated, he can do blacksmith work and is very popular in his village. He can be considered a capable person. The second uncle has never learned any crafts, but he has a good blacksmith job. After the rural joint production responsibility system, farmers were busy with one and a half acres of land and had a lot of free time, so the second uncle pooled some money and opened a blacksmith shop in front of his house. I was not very skilled at the beginning, so I just made small and inconspicuous things. The second uncle spent all day in the shop thinking about it. He took apart some things, took them apart and made them again. He kept studying, and slowly he was able to make many things. Some scrap steel can be made into plows, rakes, shovels and other practical agricultural tools through the hands of the second uncle. The farm tools made by the second uncle are exactly the same as the ones bought. Gradually, more and more villagers come here to make farm tools. . One time, I followed my second uncle to his shop. A farmer uncle came and asked my second uncle to make a windmill, because the autumn harvest was about to be crushed. The farmer uncle pressed me hard and said, "Let's make it tomorrow." "Second uncle agreed without saying a word. I asked my uncle, "Can you do it?" The second uncle said, "This is my first time making a windmill. Let me give it a try." It seemed that the second uncle was not sure. He squatted on the ground, holding his face with his hands. The black eyes rolled back and forth in their sockets. For a long time, the second uncle smiled and said: "Yes." Then there was a tinkling sound in the shop, sawing wind blades, drilling holes, and pulling out screws.

The welding started, and sparks flew everywhere. The second uncle was welding while inspecting the welded places. He was so serious and careful that I was afraid that the farmer uncle would not be able to see the goods. I only saw the second uncle’s face being burned by the fire. It turned into a red copper color, and beads of sweat kept rolling down, and he said distressedly: "Uncle, just slow down and do it." The second uncle said without moving his head: "It's nothing to be tired. The party's policies are good now. Encourage farmers to make more money. If they work slowly, can they become well-off? "Yes, my second uncle has made a lot of money with his hands in the past few years. He built a new tile-roofed house and bought a farm vehicle. He has all the household appliances and a telephone, and his life is prosperous. Although he is not yet rich, it has changed the old appearance of his family. In less than half a day, a beautiful windmill was ready. It was installed on the motor and tried. "Woo!" The windmill started to spin. The wind was very strong. I heard the uncle watching: "Master Li, how can you do that?" "The second uncle looked at the windmill and listened to the praises of the villagers. Needless to say, he looked so energetic. I really envy the second uncle's dexterous hands.

I am proud to have such an uncle.
