1. Until the bloated colonel with the big fat mustache whirled upon him savagely with a purpling face, he offered the explanation that made him immortal
    直到后来，那个蓄着两大撒粗口髦的趾高气扬的上校猛然回过头来，涨红了脸，凶神恶煞般对他看着，这时他作了使他流芳百世的说明。

2. As the sun neared its setting and the fading light became a soft purpling where horizon met sky, we settled down, with no need of words, listening to the quietening sounds of day.
    夕阳西斜，天地相接的地方，渐暗的光线变成柔和的紫色。这时我们舒服地躺了下来，无需任何言语，只消聆听万籁渐静的声响。
