动词第三人称单数形式讲解【1】 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speakspeaks, likelikes, playplays 2、以s, x, sh, ch, o 结尾的加es,如 washwashes, gogoes, dodoes, watchwatches 3、以辅音字母+y 结尾的,改y 为i 再加es,如 studystudies,trytries 4、特殊变化,如 havehas 四、does和doesn’t 在句子中的用法 否定句:主语+don’t/doesn’t+动词原形+(其他)。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. 他不看电视。 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+(其他)。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? By bike. How does Jane go to school? By bus. 五、动词第三人称单数形式的练习 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________ 2022年3月23日;第1页共2页 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. 11.You always _______(do) your homework well. 12.She _______(go) to school from Monday to Friday. 13.Liu Tao _______(do) not like PE. 14.The child often _______(watch) TV in the evening. 15.Su Hai and Su Yang _______(have) eight lessons this term. 16.
