"Teacher Zhao excels in drawing" 或 "Teacher Zhao is skilled in drawing."

这句话的来源：来源于一般英语中描述某人擅长某项技能的表达方式。

例句：

"Teacher Zhao excels in capturing the essence of his subjects in his drawings."
(赵老师擅长在他的画作中捕捉他的主题的本质。)
"His skills in drawing have earned him recognition from both his peers and art lovers."
(他的绘画技巧使他受到了同行和艺术爱好者的认可。)

Note: 个人建议把“画画”翻译成drawing，因为它更专业，也更常见。
