thief的复数形式是什么? 英语
网友回答
【答案】 thieves
以-f或-fe结尾的名词,一般将-f,-fe去掉,加-ves.如：wife-wives,wolf-wolves,calf-calves.
这类名词还有：life,knife,self,shelf,leaf,thief,sheaf,half等.
名词scarf,wharf,hoof,handkerchief的复数形式或加-s或去掉-f加-ves,即scarfs或scarves,wharfs或wharves,hoofs或hooves,handkerchiefs或handkerchieves.
也有些以-f或-fe结尾的名词只加-s.如：cliff-cliffs,belief-beliefs,safe-safes,roof-roofs,chief-chiefs等.
