动词变为第三人称单数形式的规则：
(1)在一个句子中,如果主语人称既不是你,也不是我,而是另外的一个人,这时的人称叫做第三人称单数.
(2)在第三人称单词的句子中,动词要使用第三人称单词形式.
(3)动词变为第三人称单数形式,要遵循以下规则：
①一般情况下,在动词的后面直接加s.如：
read--reads make—makes write—writes
②以字母s,x,o ,sh ,ch结尾的动词,在词尾加es.如：
do—does wash—washes teach—teaches go—goes pass—passes
③以y结尾的动词分为两个情况：
A:以元音字母加y结尾的动词,在词尾直接加s.如：play—plays buy--buys
B:以辅音字母加y结尾的动词,要把y变为i,再加es.如：study--studies
④特殊变化：have—has He ______ three new teachers.
一般词尾加s：（清清；浊浊；元浊）
ch,s,sh后+ es：读/iz/
o结尾 + es：go,do—goes/g əu z/,does/ d ʌ z/
辅+ y结尾变i加es：读/z/
特殊：have—has

现在进行时
百科名片
现在进行时表示动作发生的时间是“现在”，动作目前的状态是“正在进行中”。所谓“正在进行中”，是指在谈到这件事的时候，这个动作还在进行中。至于它是什么时候开始的，什么时候会停下来，不是我们关心的。所以“正在进行时”的事件，可能发生几年了，也可能只有几分钟。仍在进行中这是“正在进行时”的关键所在。它是一件持续进行的事情。
