英语…times more than…到底是几倍?

在我国外语界,对英语A is three times more than B的确切含义说法不一,大有令人莫衷一是之感。请看例子:例1 Your house is three times larger than mine.你的房子比我的房子大三倍(就是我的房子的四倍大小)此例句见于葛传椝先生编著的《英语惯用法词典》。葛先生强调:“只可以说‘Twenty-one is three times as much as seven.’不可以说Twenty one is three times morethan seven.”显而易见,他认为“…times mose than”是“多几倍”也即:“是n+1倍”。
