In the family of the ducks, the lamellae are first used as teeth, then partly as teeth and partly as a sifting apparatus, and at last almost exclusively for this latter purpose.

在鸭科中，薄片首先用作牙齿， 然部分用作牙齿， 部分用作分器具， 最全用于者的目的。

The 'yellow ground' had to be smashed up with picks so that  it could be coarsely sieved in large wire frames, and the resulting large pieces removed by  buckets to be further sieved and scraped.

“黄土”需用镐击碎，以便在大铁丝中进行粗，用铲斗将出的大块物料取出，进行进一步的分和刮选。

Sometimes that character commands our respect, for its sieved residue is sound, and we do not hold it against a man that he goes in rags and cannot or will not work for a living.

有时，这种性格会赢得我们的尊重，因为它的分残留物是好的，我们不会因为一个人衣衫褴褛、不能或不愿工作谋生而反对他。
