cloth/cloths/clothes

cloth 是不可数名词, 意为“布料”“织物”(material made from cotton, wool, etc)。

I wanted to have a suit made so I bought three and a half yards of cloth. (NCE, Book 2, L. 81) 我想让人给我做一套衣服，所以我买了三码半布料。

当 cloth 用来指特定用途的布(tablecloth, deskcloth)时, 它是个可数名词, 可以有复数形

式cloths:

1. She cleaned the window with an old cloth. 她用一块破布擦窗户。

2. Have you any cloths for polishing the furniture? 你有擦家具的布吗?

clothes[kləuðz]则是指“衣服”，只有复数形式：

1. He wore ready-made clothes. 他穿着做现成的衣服。

2. He soon changed into the dead man's clothes. (NCE, Book 2, L. 81) 他立即换上了死者的服装。

因此,上面的广告应写成:Children's clothes for sale.
