The crow knows to disgorge its food in order to feed its parents .
鸦知反哺。
Crows cawed from the poplar trees overhead.
白杨树上的乌鸦在上空呱呱乱叫。
※A good healthy body is worth more a crown in gold. 健康的身体贵于黄金铸成的皇冠。 ※As the old cock crows, so doth the young. 有其父必有其子。 ※Crows do not pick crow's eyes. 同室不操戈。 ※Every cock crows on its own dunghill. 夜郎自大。 ※The crow thinks her own birds fairest. 乌鸦总以为自己的雏鸟最美丽。 ※The end crowns the work. 工作成败要看结果。 ※No cross, no crown. 无苦即无乐。 ※No pain, no palm; no thorns, no throne; no gall, no glory; no cross, no crown. 不劳则无获,共难才得福,有荣必有辱,无苦即无乐。 ※One crowded hour of glorious life is worth an age without a name. 光辉生活中忙迫的一个小时抵得上无为的一世。 ※Quietude is the crown of life. 安静是生命的皇冠。
