How to write the composition of Unit 6 in the first volume of Grade Four?

The composition of Unit 6 in the first volume of Grade Four reads like this:

The stars are shining in the night sky. After finishing my homework, I casually opened the Chinese book. Inadvertently, my eyes fixed on a photo. A little girl of Han nationality and a grandmother of Miao nationality hugged each other tightly. I look at this painting, and a warm current slowly overflows in my heart. ...

In a small mountain village with continuous mountains, there is an old cabin at the head of the village. The cabin has been weathered and worn out. But when I walked into the room, the room was clean and tidy, especially warm.

An 80-year-old grandmother lives in the house. Her face is covered with wrinkles, like a dry ditch on the Huangshi Plateau. She is wearing Miao costumes, a brown lace scarf, a black robe embroidered with beautiful finale on the sleeve door, and white earrings on the earlobe! Grandma's children all go out to work and come home once or twice a year. Grandma has to do all the housework herself.

It was a sunny day. Grandma wanted to wash a lot of clothes, but she was too old to walk, so she was clumsy. Just as Grandma was in a hurry, she heard the cry of "Grandma, Grandma …" from outside, and then a little girl with croissants came in. She was panting, and the flowers on the croissant were flying like two butterflies.

She is a neighbor's little girl and has come to visit her grandmother. Seeing her sad face, I quickly took the clothes from her hand to wash them. She soaked the dirty clothes in the washbasin, and the washboard was next to the washbasin. She picked up the clothes, smoothed them, soaped them, and rubbed them with her strong little hands.

The movements were so skillful that the dirty clothes seemed to sing a happy song under the rubbing of the little girl, and the soap bubbles in the basin became excited and almost overflowed the basin. A dirty dress was cleaned by the little girl.

The little girl hung the washed clothes on the bamboo pole, and a gust of wind blew, and the clothes on the bamboo pole rippled like beautiful pictures. The old woman looked at the little girl's little hand, which was red with cold, and she was very distressed. She put her arms around the little girl, and her eyes were still full of moving tears.

The afterglow of the sunset filled the mountains, grandma's hut, grandma's face and her face was red. My eyes narrowed into a line, like a happy flower ... I gently closed the Chinese book and couldn't help thinking: it's not that relatives are better than relatives. Caring is the most beautiful emotion in the world. We should pass on this caring.
