动词第三人称单数形式讲解,一、什么是第三人称单数？ 人称可分为三类：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、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，也包括单个的动物、东西等。,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、动词三单的变化规则：1、一般情况下直接加s，如speak-speaks, like-likes, play-plays 2、以s, x, sh, ch, o 结尾的加es，如 wash-washes, go-goes, do-does, watch-watches 3、以辅音字母+y 结尾的，改y 为i 再加es，如 study-studies，try-tries 4、特殊变化，如 have-has,四、does和doesnt 在句子中的用法 否定句：主语+dont/doesnt+动词原形+（其他）。如： I dont watch TV. 我不看电视。 当主语为第三人称单数时，要用doesnt 构成否定句。如： He doesnt watch TV. 他不看电视。 注意doesnt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+（其他）。如： Do you watch TV? Yes, I do. / No, I dont. 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 doesnt.,A、写出下列动词的第三人称单数。 drink _ go _ stay _ make _ have_ pass_ carry_ come_ plant_ fly _ study_ brush_ look _ teach_ watch_,B、用括号内动词的适当形式填空。 1.He often _(have) dinner at home. 2.We _ (not watch) TV on Monday. 3.Nick _ (not go) to the zoo on Sunday. 4._ they _(like) the World Cup? 5._ your parents _(read) newspapers every day? 6.The girl _(teach) us English on Sundays. 7.She and I _(take) a walk together every evening. 8.Mike _(like) cooking. 9.They _(have) the same hobby. 10.My aunt _(look) after her baby carefully.,C、选出正确的答案： 1.
