什么情况下谓语动词用三单
谓语动词用不用“单三形式”，主要取决于句子的主语。以下几种情况可以使用动词单三形式：
1、第三人称单数he she it 做主语
2、非谓语动词(动词不定式，动名词)做主语
3、再就是比如时间，长度等作主语时当作单数来用
动词的第三人称单数形式（简称单三式）
1．一般在词尾加“-s”help-helps make-makes ride-rides know-knows
2．在s z x sh ch 结尾的词在词尾加“-es”push-pushes pass-passes watch-watches wash-washes
3．以“元音字母＋y”结尾时，加“-s”；以“辅音字母＋y”结尾时，变 y为i，再加“-es”play-plays stay-stays study-studies carry-carries
4．以“辅音字母＋o”结尾的词，多数在词尾加“-es”go-goes do-does
5．be动词的单三式为is 6．have动词的单三式为has
主语是单数形式时，或者主语是不可数名词时
