第一人称改为第三人称时
谓语动词要作相应的变化
如果是
一般现在时,第一人称变为第三人称单数时:
1 be 动词中的am要改为is , 如 I am a student . -> He/ She is a student .
have 改为has , 如 I have a pen . -> He / She has a pen .
2
实义动词作谓语时,变第三人称单数时谓语动词要加s / es,动词第三人称单数的变化规则是:
1)一般在词尾加s,如 open - opens
2)以s ,x ,ch ,sh ,o 结尾时,直接 在后面中es ,如 pass - passes ; fix - fixes ; watch - watches ; wash - washes , do - does
3)以
辅音字母加y 结尾时,变y 为i 再加es,如 carry - carries
例句:
1) I go to school on foot . -> He goes to school on foot .
2) I help Jim clean the windows . -> She helps Jim clean the windows.
3) I do my homework in the evening.-> He does his homework in the evening .
如果是
一般过去时,实义动词作谓语时都是用过去时(不受人称和数的影响)如
I did my homework just now.
He did his homework just now .
