一般现在时(实意动词).pptxVIP

一.第三人称单数形式的词尾变化.

在一般现在时中,当主语是第三人称单数形式时,行为动词用第三人称单数形式,即加-s或–es.具体方法如下:

一般情况下,直接加1s.如:2work---worksplay---plays3rain---rainssee---sees4

以sh,ch,s,x或o结尾的词后加-es.如:01wash---washesteach---teaches02fix---fixes03do---does04go---goes05

以辅音字母加-y结尾的,先把y变成i,再加es.如:study---studiesfly---fliescarry---carries
