"a dull lackluster life"
"a lusterless performance"
"staring with lackluster eyes"
"lusterless hair"
初秋的日子是黯淡、萧条的。
The day was cool and rather lustreless; the first note of autumn had been struck.这天天气阴凉,光线暗淡,秋色已开始来临。
Prince Bagration turned to the officer of the suite and stared at him with his lustreless eyes in silence.巴格拉季翁公爵把脸转向侍从军官,用那无神的目光默默地朝他瞥了一眼。
