你谈到的两种说法都正确,而且互不矛盾。
使役动词典型用法:
let/have/make sb do sth—— sb be made to do sth使/让/叫某人做某事
have sb/ sth doing 使某人或物处于某状态或不断做某事
have sth/sb done 【宾语sth/sb 是被动关系】
特殊使役动词 get sb to do sth
感官动词:
see/watch/notice/observe/find/catch/look at/ hear/listen to /feel 后面都可以接三种非谓语形式:
sb do sth 主动语态中用省略to的不定式,强调动作全过程;
sb/sth doing 强调动作正在进行
sb/sth done 过去分词,表明 宾语 sb/sth 与后面的动作是被动关系。
例如:
A cook will be immediately fired if he is caught smoking in the kitchen.
