二听四看一感觉,使役动词有三个。或:一感二听三使四看。
一感;feel 二听:hear,listen to
三使:make ,let ,have 四看:look at,see,watch,notice
使用口诀:感使动词真奇怪,to在句中象妖怪。 主动句里它走开,被动句里它回来。
动词let要除外,to词可来可不来。
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:
4.不规则动词(特殊情况):
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.
