在英语中，可以用 "art teacher" 或 "art instructor" 来指美术班老师。这些词是从英语单词 "art" 和 "teacher" 或 "instructor" 派生出来的。

一些英文例句和中文翻译如下：

"My art teacher is really talented and has been teaching us new techniques every week."
(我的美术老师真的很有才华，每周都会教我们新技巧。)

"I really enjoy my art class because our instructor is so patient and explains everything clearly."
(我真的很喜欢我的美术课，因为我们的讲师非常耐心，并清楚地解释每件事。)

"I took an art class over the summer and my teacher was a professional artist who had a lot of experience."
(我在暑假参加了一个美术课，我的老师是一位专业艺术家，有很多经验。)
