1、动词第三人称单数形式 主语有三单,动词也有三单,快点来习惯,体会在心里,一定要过关.一、 概念动词第三人称单数：主语是第三人称单数，即谓语动词的发出者是it、she、he、可数名词单数、不可数名词等表示单数概念的词时，实义动词后面要加-s或-es。注意：假设主语不是第三人称单数形式，就直接用动词原形；假设主语是三单，后有will等情态动词修饰时，动词也用原形。二、 动词三单变化规那么只有一般现在时才有第三人称单数动词第三人称单数的变化规那么及发音规律，同名词单数变复数大致一样，请认真观察。1、 大多数实义动词在词尾加“s，在清辅音后发音为/ s / ，在浊辅音及元音因素后发音为 / z /。

2、如：speakspeaks /s/ ; comecomes /z/ ; playplays /z/2、 以辅音字母加“y结尾的动词，要先将“y变为“i，然后再加“es，读/z/。 如：studystudies /z/ ; flyflies /z/ 3、 以“s，x，ch，sh结尾的动词，在词尾加“es，发音为/ iz / 。 如：teachteaches /iz/ ; watchwatches /iz/ 4、 以“o结尾的动词,在词尾加“es。 常出现的两个以“o结尾的动词go与do后加“es，读/z/ 。 如：gogoes /z/ ; dodoes /z/ 5、 记住最为特别的be的三单is

3、 ；have的三单是has。注意1下面两个动词变三单时，原词的元音局部的发音发生了较大的变化，要记忆。 如：do/du:/ does/d z/ ; say/sei/ says /sez/ 2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： closecloses iz 三、 动词第三人称单数的句子构造。1、 肯定/否认句 三单+is +表语 . 三单+动词第三人称单数+其他 . 三单+is+not+表语 . 三单+doesnt +动词原形+其他 .2、 一般疑问句 1当谓语动词是be动词时，一般疑问句构造为“Is+三单+表语？。它的肯
