① Different kinds of cloth are produced in that factory. 那家工厂生产各种各样的布料。
② My aunt bought me two pieces of cloth yesterday. 我姑妈昨天给我买两块布。

Ⅱ. clothes “衣服”，没有单数形式，不能单独与数词直接搭配。如不能说hour clothes, 但可以说many/ these/ a few clothes,它总是以复数形式出现，因此只能说: The clothes are… 如：

Ⅳ. dress 通常指外面穿的衣服。一般指妇女和儿童服装，还指礼服或某种特殊的服装。是可数名词。如：
① Who’s that girl in red dress? 穿红衣服的那位姑娘是谁?
② What size dress do you wear? 你穿几号衣服?
③ He doesn’t care much about dress? 他不太讲究衣着。(他不讲穿)。
④ He is in full dress. 他穿着礼服。
