动词变单三式的变化规则
(完整版)动词变第三人称单数规则

动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同。
1、大多数动词在词尾加“S”在清辅音后发音为[s],在浊辅音及元音后发音为[z]。
如:①stop-stops [s] ; make-makes [s]②read-reads [z] ; play-plays [z]2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz] 如: fly-flies [z];carry-carries [z]study-studies [z]; worry-worries3、以“s, x, ch, sh”结尾的,在词尾加“es”,发音为[iz] 如:teach-teaches [iz]; watch-watches [iz]4、以“o”结尾的动词,加“es”,读[z] 如:go-goes [z] do-does [z]下面几个动词变为单数时,原词的元音部分的发音发生了较大的变化,请注意记忆。
如:1、do [du:]-does [dz]2、say [sei]-says [sez]以不发音字母“e”结尾的开音节词,如果尾音是[s],[z]时,加“s”后字母“e”发音,与所加“s”一起读做[iz]。
如:close-closes [iz]be动词包括:am,is,are。
第三人称单数用is;过去式为was;复数用are,过去式为were.除上述规律外,还应注意下面三点:1. 动词have ,遇到主语是第三人称单数时,要用has;动词be 的第三人称单数形式是is。
2. 含有动词第三人称单数形式的句子变否定句时,要用doesn't + 动词原形,如:He goes to school at six in the morning. (变否定句)→ He doesn't go to school at six in the morning.3. 对含有动词第三人称单数形式的句子提问时,要用助动词does,如:She goes home at five every day. (对划线部分提问)→ When / What time does she go home every day?一般现在时中的第三人称单数形式在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。
