棉羊在英语中被称为"cotton sheep"，因为它们能够产生棉花。这种羊与其他品种相比，体型较小，身体有着浓密的白毛，因此在棉花产地特别常见。例句如下：

The cotton sheep is a popular breed in cotton-growing areas because of its dense white coat.

Cotton sheep are smaller and have a thicker white coat than other breeds.

Cotton farmers often raise cotton sheep because of their ability to produce cotton.
