“突破界限”
用英语怎么说？

Warhol began his studies in 1945 but struggled through his first-year courses. To refine his draftsmanship, he took a summer drawing class while working alongside his brother selling produce from a truck. He sketched customers in his spare moments, and these sketches earned him a scholarship. During college, Warhol started experimenting with his famous blotted-line technique, combining drawing with printmaking. Throughout his career, Warhol had a deep fascination with self-portraits. He often recreated his own likeness using photobooth strips and colorful silkscreens. His nephew recalled that the inspiration for "Nosepicker" came from his father's complaints about children picking their noses. Although some people found the topic inappropriate, Warhol believed that being offensive could work in the art world. He possessed a keen sense of humor and was never afraid to push boundaries.

沃霍尔于1945年开始学习，但艰难度过了第一年的课程。为了精进画功，他在和哥哥一起从卡车上卖农产品的同时，参加了暑期绘画班。他在空闲时间为顾客素描，这些素描为他赢得了奖学金。在大学期间，沃霍尔开始尝试他著名的吸墨线条技术，将绘画与版画制作相结合。在沃霍尔的整个职业生涯中，他都对自画像有着深深的迷恋。他经常利用照相亭底片和彩色丝网印刷来重现自己的肖像。他的侄子回忆说，《抠鼻子》的灵感来自他父亲对孩子们抠鼻子的抱怨。尽管有些人认为这个主题不合适，但沃霍尔相信，在艺术界，具有冒犯性可能行得通。他有着敏锐的幽默感，并且从不害怕突破界限。
