how much is that pair of socks?回答是it is还是they are

优质解答

不能用单数代词代替pair,尽管它做主语谓语用单数.
要用They are.

追问：

回答是代替pair一条讲时不可以吗

追答：

不可以. pair 一词一般不用it, one 一类的词代替
如:
This pair of glasses is broken. I'll have to buy a new [pair]
不能说:
This pair of glasses is broken. I'll have to buy a new [one].

此句不用it, 与例句同理!

追问：

一般不用it,one代替这是语法现象吗

追答：

是的
