询问几个动词

let sb do sth
have sb do sth/have sth done
tell sb to do sth
get sb do sth/get sth done
say sth
like to do sth/like doing sth
need to do sth/need doing (need to be done)

let+动词原形
have sb.do/done
tell sb. to do
get sb. done/doing
say to sb
like doing/to do
need do/to do

楼上的都对
我还补充一下
need也可以作情态动词need do sth. 否定是needn't do sth.
