Sunshine Cambridge Foreign Languages School 动词的第三人称单数形式详解 一、什么是第三人称单数？ 人称分为三类：第一人称，第二人称和第三人称。 第一人称：I, we 第二人称：you 第三人称：he, she, it, they和人名类（如： Peter, Jane, Liu Yun, my father等）。 结合以上知识，第三人称单数就是he, she, it和单个的某人，也包括单个的小动物。 二、动词为什么要变成相应的三单形式？ 在一般现在时中，跟在第三人称单数后面的动词也要变成相应的三单形式。例如： I watch TV every day. 如果主语是三单，动词要变化： He watches TV every day. She watches TV every day. Jane watches TV every day. 三、动词三单的构成规则： 1．一般情况下，直接加-s，如：play-plays, see-sees, listen-listens 2．以s. x. sh. ch. o结尾，加-es，如：guess-guesses猜, wash-washes洗, watch-watches, go-goes, do-does做 3．以“辅音字母+y”结尾，变y为i, 再加-es，如：study-studies学习 4. 特殊变化：have-has 四、does和doesn’t 在句中的用法： 否定句：主语+ don’t / doesn’t +动词原形(+其它)。如： I don’t watch TV. 我不看电视。 当主语为第三人称单数时，要用doesn’t构成否定句。如： He doesn’t watch TV. 注意doesn’t 后面用动词原形watch, 而不是watches. 一般疑问句：Do( Does ) +主语+动词原形+其它。如： Do you watch TV? Yes, I do. / No, I don’t. 当主语为第三人称单数时，要用does构成一般疑问句。如： Does she watch TV? Yes, she does. / No, she doesn’t. 特殊疑问句：疑问词+一般疑问句。如： How do you go to school? How does Jane go to school? By bike. By bus. 专项练习 一、 写出下列动词的第三人称单数形式。 (每题2分) drink ___________ go __________ stay ___________ make __________ look __________ have_________ pass_________ carry _________ come__________ watch_________ plant__________ fly ___________ study__________ brush___________ do____________ teach__________ 第 1 页 共 2 页 阳光剑桥 Sunshine Cambridge Foreign Languages School play___________ eat___________ see___________ read___________ 二、用括号内动词的适当形式填空。(每题2分) 1.
