“往死练”的英文意思是“to practice to the point of obsession”。这个短语源自于某个类似“日日夜夜练习，直至死亡”的俗语，表示为了达到某个目标而练习过度。例如：

She spent hours practicing the piano every day, determined to become a concert pianist. She was determined to practice to the point of obsession.
I've been working on my basketball skills for hours every day. I'm determined to practice to the point of obsession so I can make the team.

中文翻译：

她每天花费几个小时练习钢琴，决心成为一名钢琴家。她决心往死练。
我每天花费数小时练习篮球技巧。我决心往死练，以便能够加入球队。
