素描是造型艺术的基础，是画家认识自然、研究自然、表现自然的开端。他们从素描中得到对自然规律的理解，得到多因素表现自然的形式和技法，又通过素描找到自身风格雏形和艺术价值。一个画家总是从步入素描开始走进艺术家殿堂的。所以，在基础教学中，素描教学显得尤为重要。? Drawing is the foundation of plastic arts, and it is the beginning of the artist’s understanding of nature, the study of nature, and the expression of nature. They get an understanding of the laws of nature from the sketches, get the natural forms and techniques of multi-factors, and find their own prototypes and artistic values ​​through sketches. An artist always starts walking into the artist’s hall from the sketch. Therefore, sketch teaching is especially important in basic teaching. ?
