名词变复数及练习题 (2)ppt课件

1、名词单数变复数口诀 (一)规则变化 名词单数变复数，直接加-s占多数； s,x,ch,sh来结尾，直接加上-es； 词尾是f或fe，加-s之前先变ve； 辅母+y在词尾，把y变i再加-es； 词尾字母若是o，常用三个已足够， 要加-es请记好，hero,tomato,potato。,1,1.英语名词有单数和复数的区别，单数表示“一”， 复数表示“多于一。”名词由单数变复数，多数是规则的变， 直接加-s，例如：bookbooks,girlgirls。 但以-s,-z,-x,-ch,-sh结尾的名词，变成复数时加-es, 例如：busbuses,buzzbuzzes,boxboxes, watch
