Ask sB Do还是to Do

ask sb. to do sth.要求某人做某事

没有ask sb do sth的用法, ask 的后面跟的是一个不定式短语.只有ask sb. to do sth. 请求某人做某事.I have to ask David to wait in the vestibule 我只好让大卫在前厅等著.He asked his doctor to tell him whether his operation had been successful. 他请求大夫告诉他,他的手术是否成功.希望采纳谢谢

ask sb to do sth的意思是让某人做某事ask sb for sth的意思是向某人索取某物意思不一样的

ask sb to do sth

ask sb. to do sth. 是正确用法.1、并没有ask sb. doing sth.这个说法, 请求别人做的事情是未发生的,不能用进行时.2、让某人做某事句型还有: make sb. do sth. ;let sb. do sth.;have sb. do sth;get sb. to do sth. 等.3、接双宾语句型:Subject

是ask sb to do 没有ask to do sth.如果硬是要说有只有被动的了 比如:sb be asked to do sth 某人被要求做某事

这是固定用法,及物动词后不加to,不及物动词要加to,ask属于不及物动词,所以应该是后者ask sb. to do sth

因为前者的两个sth可以用同一个do来执行 而后面的两个sth 各自有各自的do~ 比如穿衣和吃饭,动词不一样

ask sb. to do 是正确的!有问题可追问,期待帮你更多!

ask sb to do sth 让某人做某事.
