This pair of pants is().Can I()?

问题描述:

This pair of pants is().Can I()?
enough cheap;try on them
cheap enough ;try them on
enough cheap ;try on it
cheap enough;try it on
为什么用it,it不是指不可数的吗?pants是可数名词啊,用them为什么不行.

选择第四个答案.因为enough要放在形容词后,因为是pair of pants,主语是pair of pants,重点强调pair,因为pair是单数,所以后边的代词指代pair of pants,也要用单数it代替.
