Clothes是衣服、服装的泛称,通常指多件不同衣服(如:上衣、裤子、袜子等)的搭配。这个词本身是复数形式,Wiktionary指出,该词是:“plural only”,即:仅表示复数。相应的,clothes后面的系动词也该用复数,如:clothes are,clothes were,而不使用clothes is,或clothes was。
由于clothes本身是复数,因此前面不可使用“一件”(a piece of,an article of,或an item of)这样的修饰词。
例如:
These clothes are mine.(这些衣服是我的)
His clothes are in the closet.(他的衣服在柜子里)
The clothes were shipped yesterday.(衣服昨天已发货了)
如果你要表示一件衣服,可以用clothing。如:a piece of clothing,或an article of clothing。
