动词单三变化规则

1.一般情况下,直接在动词词尾+s:

2.以s,x,sh,ch,o结尾的动词,在词尾+ es:

3.以辅音字母+ y 结尾的动词,先把y变为i,再加es:

变否定句时遵循的规则

含有动词第三人称单数形式的.句子变否定句时,要在动词前面加上doesn’t 或does not,动词的第三人称单数形式要还原成原形:格式为doesn’t/does

not+ 动词原形,如:

He goes to school at six in the morning. (变否定句) 就变换为:

He doesn't go to school at six in the morning.

2.变一般疑问句:把含有动词第三人称单数形式的变成一般疑问句时,要借用助动

词does,如:

She goes home at five every day.(变疑问句)就变换为:

Does she go home at five every day? -- Yes,she does./No,she doesn’t.
