When someone is knitting a scarf or a sweater the phrase knit one purl two mightfit the context, but in this case the purl is a different word spelled PU R Land comes from a source meaning “twist.”
而当某位女士针织围巾或是毛衣的时候，她所用的口诀“正一针，倒两针（knit one, purl two）”也许挺符合本文的语境。 不过，这个例子里的单词purl拼写却完全不同——P U R L ——它的来源有着“旋转（twist）”的意思。
