勇往直前的英文说法是"advance boldly"。这个短语来源于英国作家威廉·莎士比亚的戏剧《哈姆雷特》中的一句台词：“The native hue of resolution / Is sicklied o'er with the pale cast of thought, / And enterprises of great pith and moment, / With this regard their currents turn awry, / And lose the name of action.--Soft you now, / The fair Ophelia!--Nymph, in thy orisons / Be all my sins remember'd.”（毅力的本性色彩被思想的苍白阴影覆盖，大举大动的企业也被这种影响扭曲，而失去了行动的名号，哦，良宵，美丽的奥菲利亚女神，在你的祈祷中，请记住我所有的罪过。）

  例句：

  1. He advanced boldly into the unknown territory.

  2. She took a deep breath and advanced boldly into her speech.

  3. We must advance boldly into the future, ready to face whatever challenges come our way.
