Alia was disappointed. She had been sick when everyone else selected their courses. She had hoped for science, but by the time she chose, the science classes had already been full. She had to take the art class. Alia loves science because it uses facts and rules to explain how things work, but art is so unscientific(不科学的).
The first class project was drawing self-portraits(自画像). Some students drew using mirrors, while others worked from photos. She saw her classmates looking carefully at their faces and then drawing slowly. Alia, however, felt out of place.
The teacher walked over and said,“Every portrait starts with a circle. Then we add lines and a triangle to place the eyes, nose, and mouth.” He drew a few small portraits to show the detailed steps. Alia noticed the features on the faces of the portraits were in almost the same places. Alia nervously began her own self-portrait. She found it interesting to measure where to put her eyes and mouth. She drew the basic shape of a head, and then used lines to add the features. She had to pay attention to every detail. One wrong line could mess everything up.
Alia was surprised by how much effort drawing required. It required measuring, noticing details, and showing the basic nature of something. It made her realize art could be scientific in its own way. She understood that art also has its rules and steps, just like science. By the end of the project, Alia felt thankful for the experience. It allowed her to see art in a new light.
