主语为第三人称单数的动词变化主要体现在词尾的变化上, 其规律 大体有三点: 1. 一般情况下,直接在动词词尾+s ,例如:get→gets; take→takes 2. 以 s, sh, ch, x, o 结尾的动词,在词尾+ es,例如: teach→ teaches; go→goes 3. 以辅音字母+ y 结尾的动词,变 y 为 i,再+ es, 如:study→studies; try→tries 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? 学习很快乐 请及时采纳,谢谢 (≧◇≦)
watches?作动词时,意思是观看,名次是钟表的意思
he \she \it watches TV every night.
