1、小学五年级英语语法总结一、词语 1、名词 这里强调两点：不可数名词都默认为单数，所以总是用is 名词复数如何加后缀： 各种不同情况 一般情况 以s. x. sh. ch结尾 变化方法 直接加-s 加-es 例词 book-books bag-bags cat-cats bed-beds bus-buses box-boxes brush-brushes watch-watches peachpeaches glass-glasses 以“辅音字母变y为i, 再加family-families study-studies +y”结尾 -es 以“f或fe”结变f或fe为v，knife-knive
