Question

‘amount’作为‘金额’解释时是否可数?

Answer 1

比如翻译这么一句话：两张发票上的金额不同.（指本应相同的,一式两联的发票）以下那几句正确?1）The amounts on the two invoices differ from each other.2）The amount on the two invoices differ from each other.3) The amount on the two invoices differs fromeach other.4）The amount of the two invoices are different.我知道如果换成invoice为主语就避免了以上的疑问,即The two invoices differ in amount.但还是想知道amount作主语的情况,以及相应的动词形式.
