1、!-第三人称单数是英语中的一种语法，也称“三单”或“单三”，用于一般现在时的句子，当动词在第三人称后时：情况方法示例一般情况+slet-lets;get-gets以s、x、ch、sh和o结尾+espass-passes;fix-fixes;watch-watches;teach-teacheswash-washes;go-goes;do-does以辅音字母+y结尾变y为i +esstudy-studies以元音字母+y结尾直接+splay-plays特殊情况不规则have-hasbe-is首先，咱们要搞清楚第一、第二、第三人称各是什么。第一人称就是“我”和“我们”。第二人称是“你”和“你们”。
